As shown in fig. 1-3, the display apparatus provided by the present invention includes a display device layer 100 and a lenticular layer 200 disposed on the display device layer 100.

One side of the display device layer 100 is the light emitting side 100-a. To ensure uniform light emission of the display device layer 100 and to facilitate cooperation with other device layers, the light emitting face 100-a is a straight face.

The lenticular layer 200 includes a plurality of lenticular structures 201, and the plurality of lenticular structures 201 are disposed on the light emitting surface 100-a at equal intervals along the first direction. A plurality of lenticular structures 201 have a secondary display region 202 therebetween, the secondary display region 202 being formed by a spaced region between two adjacent lenticular structures 201.

A plurality of groups of first light emitting areas 300 and a plurality of groups of second light emitting areas 400 capable of being displayed in a partitioned mode are arranged in the display device layer 100, a group of first light emitting areas 300 are correspondingly arranged in each pillar structure 201, and a group of second light emitting areas 400 are correspondingly arranged in each auxiliary display area 202.

The first light emitting region 300 includes a plurality of sub-pixels capable of emitting light, and the second light emitting region 400 includes a plurality of sub-pixels capable of emitting light.

Note that the sub-pixel types in the first light emitting region 300 include at least one of R pixels (red pixels), G pixels (green pixels), B pixels (blue pixels), and W pixels.

Similarly, the sub-pixel type in the second light emitting region 400 includes at least one of R pixels (red pixels), G pixels (green pixels), B pixels (blue pixels), and W pixels.

A display image is formed by emitting light in accordance with a predetermined instruction through a plurality of and various sub-pixels in the plurality of first light emitting areas 300.

A display image is formed by emitting light in accordance with a predetermined instruction through a plurality of and various sub-pixels in the plurality of second light emitting areas 400.

The lenticular structure 201 is used for performing 3D display, so that the lenticular structure 201 is a lenticular lens structure, and according to the light splitting principle of the lens, the contents of different pixel positions in the synthesized parallax image displayed on the light emitting surface 100-a are projected to the eyes of the viewer at different angles, so that the viewer can feel a stereoscopic effect.

The sub display area 202 is used for 2D display, and therefore, the display surface of the sub display area 202 in the space area is a straight surface and parallel to the light emitting surface 100-a. That is, the display may be performed directly by the light emitting surface 100-a in the space region, or may be performed by providing a planar light transmitting structure in the space region.

The first direction is any direction in a plane parallel to the light emitting surface 100-a. For example, the first direction may be a longitudinal direction of the display device layer 100, or the first direction may be a width direction of the display device layer 100, or a direction of an angular bisector of the longitudinal direction and the width direction of the display device layer 100.

In order to ensure the display effect, the first light emitting region 300 corresponding to the lenticular structure 201 is located below the lenticular structure 201, and the sub-pixels of the first light emitting region 300 are all disposed on the same plane as far as possible, and the plane is parallel to the light emitting surface 100-a and is located within the coverage area of the lenticular structure 201 as far as possible.

Similarly, the second light emitting region 400 corresponding to the auxiliary display region 202 is located below the auxiliary display region 202, and the sub-pixels in the second light emitting region 400 are all disposed on the same plane, and the plane is also parallel to the light emitting surface 100-a and is as far as possible within the coverage area of the auxiliary display region 202.

In the prior art, when the display device is switched between 2D display and 3D display, external force is often adopted to intervene, so that the polarization orientation of liquid crystal molecules in the display device is adjusted or the distance between the lenticular grating device and the display screen is adjusted, and as can be known, a certain time is required for completing the operation, thus delay occurs in the switching process of 2D display and 3D display, real-time display cannot be realized, and the use experience of a viewer is reduced.

In the display device provided by the invention, the lenticular layer 200 formed by a plurality of equidistant lenticular structures 201 is arranged on the light emitting surface 100-a of the display device layer 100, and the first light emitting area 300 and the second light emitting area 400 which can be displayed in a partitioned manner are arranged in the display device layer 100, so that each lenticular structure 201 is arranged corresponding to one first light emitting area 300, and each auxiliary display area 202 is arranged corresponding to one group of second light emitting areas 400.

Based on the above-described arrangement, when 3D display is required, all the first light-emitting areas 300 are controlled to display, light-transmitting display is performed by the lenticular structure 201, and all the second light-emitting areas 400 do not display content; when 2D display is required, all the second light emitting regions 400 are controlled to display, and the sub display regions 202 in the interval region where the lenticular structure 201 is not provided display, and all the first light emitting regions 300 are not displayed.

It can be understood that the present display device can realize switching between 2D display and 3D display only by controlling whether the first light emitting area 300 and the second light emitting area 400 are displayed or not. Compared with the prior art, the display device provided by the invention does not need to have structural change in the display process, so that the time for switching the 2D display and the 3D display can be greatly shortened or even completely omitted, and the viewing experience of a user is improved.

Referring to fig. 4, in some embodiments, a light shielding region 203 is further disposed between the secondary display region 202 and the adjacent lenticular structure 201, and the light shielding region 203 adopts an opaque arrangement.

It should be noted that, since the light shielding region 203 is disposed in a light-tight manner and is located between the lenticular structure 201 and the auxiliary display region 202, the light overflowing from the first light emitting region 300 corresponding to the lenticular structure 201 toward the auxiliary display region 202 is blocked by the light shielding region 203, so that a portion of the light of the first light emitting region 300 is projected into the auxiliary display region 202 to be displayed when the second light emitting region 400 is not displayed in the first light emitting region 300, thereby affecting the display effect. Similarly, the light shielding region 203 can also avoid a portion of the light in the second light emitting region 400 from being projected into the lenticular structure 201 for display.

It should be noted that, the opaque arrangement referred to in the present application means that light of any wavelength is not transmitted.

The light shielding region 203 is disposed between the secondary display region 202 and the lenticular structure 201, i.e., one or both sides of the secondary display region 202 have the light shielding region 203 disposed. In order to improve the display effect of the display device, a light shielding region 203 is generally disposed on both sides of the sub display region 202.

Wherein the light shielding region 203 is also formed by a portion of the spacing region between two adjacent lenticular structures 201. For example, the interval region may be divided into three regions including a first region, a second region and a third region distributed along the first direction, the first region being the light shielding region 203, the second region being the sub display region 202, and the third region being the light shielding region 203.

In order to ensure that the display look and feel of the 2D display and the display look and feel of the 3D display differ little in resolution, it is necessary to provide the area of the light emitting surface 100-a occupied by the sub display area 202 to be the same as the area of the light emitting surface 100-a occupied by the lenticular structure 201. Therefore, the area of the light emitting surface 100-a occupied by the spacing region formed between the adjacent lenticular structures 201 is greater than or equal to the area of the light emitting surface 100-a occupied by the individual lenticular structures 201.

Further, the area of the light emitting surface 100-A occupied by the sub display area 202 is larger than the area of the light emitting surface 100-A occupied by the light shielding area 203.

In some embodiments, the light shielding region 203 is formed by blackening a partial region of the space region.

It can be understood that, in this embodiment, the light shielding region 203 is substantially a black-out region on one side or two sides of the sub-display region 202, and the black-out region on one side or two sides of the sub-display region 202 is not transparent, so that the light crosstalk between the first light emitting region 300 and the second light emitting region 400 can be prevented, and the display effect of the display device can be improved.

Specifically, when the sub display area 202 is directly displayed with the light emitting surface 100-a, the blackening process is directly performed on the light emitting surface 100-a.

Specifically, when the sub-display area 202 is formed of the planar light-transmitting portion 202-a provided in the space region, the blackening process is performed on the surface of the planar light-transmitting portion 202-a when the planar light-transmitting portion 202-a is provided integrally with the lenticular structure 201. When the planar light-transmitting portion 202-a and the lenticular structure 201 are provided as separate bodies at intervals, the blackening process may be performed in the interval region between the planar light-transmitting portion 202-a and the lenticular structure 201; or on both the planar light-transmitting portion 202-a and the spaced area between the planar light-transmitting portion 202-a and the lenticular structure 201.

In other embodiments, the light shielding region 203 is formed as a light shielding member disposed between the secondary display region 202 and the lenticular structure 201. That is, by providing a light shielding member in the interval region between the sub-display section 202 and the lenticular structure 201, the light shielding member therebetween is provided so as to be opaque, thereby avoiding crosstalk between the display of the lenticular structure 201 and the display of the sub-display section 202.

Specifically, when the sub-display area 202 is directly displayed with the light emitting surface 100-a, the light shielding member is directly disposed on the light emitting surface 100-a and is located between the lenticular structures 201 of the sub-display area 202.

Specifically, when the sub-display area 202 is formed by the planar light-transmitting portion 202-a provided in the space region, the light shielding member is provided on the surface of the planar light-transmitting portion 202-a close to the lenticular structure 201 when the planar light-transmitting portion 202-a is integrally connected to the lenticular structure 201. When the planar light-transmitting portion 202-a and the lenticular structure 201 are disposed separately at intervals, the light shielding member is disposed between the planar light-transmitting portion 202-a and the lenticular structure 201. That is, the lenticular layer 200 may be a structure including a light shielding member, a lenticular structure 201, and a planar light transmitting portion 202-a.

It should be noted that the light shielding member may be a light-tight sheet-like structure or a strip-like structure, or may be a light shielding layer coated on the light emitting surface 100-a or the planar light transmitting portion 202-a.

In some embodiments, the sub-pixels in the first light emitting region 300 are located on a focal plane of the pillar lens structure 201, the focal plane is a first plane where the focal point of the pillar lens structure 201 is located, and the first plane and the light emitting surface 100-a are parallel to each other.

The sub-pixels in the first light emitting region 300 are all disposed on the focal plane of the lenticular structure 201, and are substantially controlled by the distance between the sub-pixels and the lens surface of the lenticular structure 201. The sub-pixels in the first light emitting region 300 are substantially equivalent to light emitting sources, and the light emitting sources are located on the focal plane of the lenticular structure 201, so that light emitted by the light emitting sources is located at an optimal refraction position, and light spots are avoided to form, so that an optimal display effect is achieved.

In other embodiments, to maintain uniformity of the display device layer 100 and reduce manufacturing process difficulty, the sub-pixels in the second light emitting region 400 are also located at the focal plane of the lenticular structure 201.

In some embodiments, the sub-pixels in the first light emitting region 300 are all located within the projection of the lenticular structure 201 on the first projection plane. The sub-pixels in the second light emitting region 400 are all located in the projection of the sub-display area 202 on the first projection plane. The first projection plane is perpendicular to the thickness direction of the display device layer 100, and the projections of the lenticular structure 201 and the sub-display area 202 on the first projection plane are all projections taken along the thickness direction of the display device layer 100.

The light emitting surface 100-a of the display device layer 100 is perpendicular to the thickness direction of the display device layer 100. The projection of the lenticular structure 201 and the secondary display screen on the first projection plane can be regarded as the projection of the lenticular structure 201 and the secondary display area 202 on the light emitting plane 100-a in the thickness direction of the display device layer 100.

The sub-pixels in the first light emitting area 300 are all located in the projection of the lenticular structure 201 on the first projection plane, that is, the sub-pixels in the light emitting first light emitting area 300 are all located in the coverage area of the lenticular structure 201, so that the first light emitting area 300 and the auxiliary display area 202 do not display an overlapping range, thereby weakening the influence of the light emitted by the sub-pixels of the first light emitting area 300 on the auxiliary display area 202, avoiding display interference caused by light crosstalk, and improving 3D display effect.

Similarly, the sub-pixel regions in the second light-emitting region 400 are all located in the projection of the secondary display region 202 on the first projection plane, that is, the sub-pixels in the second light-emitting region 400 can be made to be located in the coverage area of the secondary display region 202, so that the second light-emitting region 400 and the lenticular structure 201 do not display an overlapping range, thereby weakening the influence of the light emitted by the sub-pixels in the second light-emitting region 400 on the secondary display region 202, avoiding display interference caused by light crosstalk, and improving 2D display effect.

In some embodiments, in order to improve the overall display effect of the display device, the technical solutions of the above embodiments are reasonably applied to the same display device. For example, in order to avoid light crosstalk between the first light emitting region 300 and the auxiliary display region 202, the sub-pixels in the first light emitting region 300 are located in the projection of the lenticular structure 201 on the first projection plane, and the sub-pixels in the second light emitting region 400 are located in the projection of the second lenticular structure 201 on the first projection plane; meanwhile, the shading area 203 is arranged between the auxiliary display area 202 and the cylindrical lens structure 201, so that the possibility of crosstalk of light rays of different display areas is further avoided, and the display effect of the display device is improved.

Further, on the basis of the above embodiment, the sub-pixels in the first light emitting region 300 are disposed on the focal plane of the lenticular structure 201.

More recently, in addition to the above embodiments, the sub-pixels in the second light emitting region 400 are also disposed on the focal plane of the lenticular structure 201.

Referring to fig. 1,2, 3 and 5, in some embodiments, the width of the pillar 201 is an integer multiple of the width of the sub-pixel, and the width of the pillar 201 is at least twice the width of the sub-pixel and more, so as to distribute at least two or more sub-pixels along the width of the pillar 201.

The width of the lenticular structure 201 is the length of the short side of the face of the lenticular structure 201 contacting the light emitting face 100-a. The pitch of the lenticular structure 201 is the width of the lenticular structure 201. That is, the pitch of the lenticular lens is twice or more the sub-pixel width.

It can be seen that the width of the pillar 201 is T, the width of the sub-pixel is d, where t=n×d, and N is greater than or equal to 2.

In some embodiments, the pitch Y between the lenticular structures 201 is the width of the lenticular structures 201, i.e. the pitch of the lenticular structures 201 is the pitch Y between two adjacent lenticular structures 201, i.e. the width of the spacing region between two lenticular structures 201.

In some embodiments, the first light emitting region 300 is provided with N sub-pixels along the width direction of the lenticular structure 201.

Specifically, the width (pitch) t=n×d of the lenticular structure 201. That is, N sub-pixels are provided in the width direction of the lenticular structure 201.

In some embodiments, the width of the sub-display area 202 is the width of the lenticular structure 201, wherein the second light emitting area 400 is provided with N sub-pixels along the width direction of the sub-display area 202.

The spacing between two adjacent lenticular structures 201 is y=t, y=t=n×d.

It can be understood that, by making the number of sub-pixels of the first light emitting region 300 and the second light emitting region 400 in the width direction of the lenticular structure 201 the same, the amount of display information of the secondary display region 202 can be made the same as the amount of display content information on the lenticular structure 201, so that the display device can be switched between 2D and 3D, the sense of difference between the two displays is reduced, and a user obtains a more user experience.

Referring to fig. 6-7, in some embodiments, the lenticular layer 200 further includes a plurality of planar light-transmitting portions 202-a, wherein the plurality of planar light-transmitting portions 202-a are disposed between two adjacent lenticular structures 201, and one planar light-transmitting portion 202-a has a sub-display area 202, or one planar light-transmitting portion 202-a is a sub-display area 202.

The planar light-transmitting portion 202-a has a light-transmitting structure that does not refract light, i.e., has a light-incident surface and a light-emitting surface that are parallel to each other, and both of the light-incident surface and the light-emitting surface are parallel to the light-emitting surface 100-a on the display device layer 100.

In some embodiments, the planar light-transmitting portion 202-a is spaced apart from the lenticular structure 201, i.e., the lenticular layer 200 includes a plurality of lenticular structures 201 and a plurality of planar light-transmitting portions 202-a, but the lenticular structure 201 and the planar light-transmitting portions 202-a are provided separately. The area formed by the light-emitting surface of the planar light-transmitting portion 202-a is the sub-display area 202.

The planar light-transmitting portion 202-a and the lenticular structure 201 have a space therebetween, which may be used for a black coating process or for providing a light shielding member.

In order to maintain the uniformity of the lenticular layer 200 as a whole, the thickness of the light shielding member is the same as the thickness of the planar light transmitting portion.

In another embodiment, the planar light-transmitting portion 202-a and the lenticular structure 201 are arranged at intervals, and the lenticular layer 200 is a light-transmitting layer, wherein the light-transmitting layer has cylindrical lens structures protruding from the surface of the light-transmitting layer at intervals, so as to form the lenticular structure 201; the light-transmitting layer is also provided with a plane protruding part protruding from the surface of the light-transmitting layer and positioned between the two cylindrical lens structures 201, and the plane protruding part forms the plane light-transmitting part 202-A; wherein, there is a space between the plane protruding part and the column protruding part, which can be used for black coating treatment or setting up the shading piece.

In other embodiments, the lenticular layer 200 is also a light-transmitting layer, and the light-transmitting layer also has the above-mentioned cylindrical lens structures and the planar protrusions, but there is no space between the planar protrusions and the cylindrical lens structures.
