Description

Glasses-free 3D display pixel unit and device with 2D or 3D switching function

technical field

The utility model relates to a display unit and its device, in particular to a naked-eye 3D display pixel unit and a device with 2D or 3D switching function.

Background technique

Since the distance between the pupils of the left eye and the right eye of ordinary people is about 6.0cm to 7.0cm, the image information received by the retinas of the two eyes is slightly different due to the difference in viewing angle, and the human brain has the ability to fuse the image information of two different viewing angles to generate depth perception. Function, so the human eye will form a stereoscopic visual effect when viewing objects.

In the field of stereoscopic display technology, existing technologies are mainly divided into: glasses-type and naked-eye 3D display technologies. The naked-eye 3D display technology uses a lenticular lens and a slit grating (parallax barrier) for most display products.

Generally speaking, naked-eye 3D display technology needs to be paired with a liquid crystal display panel to present a three-dimensional image. Not only is the process complicated and costly, but the pixel alignment and assembly accuracy of the grating and the liquid crystal panel are extremely high. Especially for large-size display screens, the defect rate and manufacturing and assembly costs of naked-eye 3D display products with gratings are relatively high, and because the process of liquid crystal panels and grating lenses has its area size constraints, it is not suitable for large-scale display screens. The area shows the application of the product.

Because the grating lens is installed in front of the liquid crystal panel to realize naked-eye 3D, 2D images or texts will be affected. Existing technologies for switching between 2D/3D display modes are mostly implemented by optoelectronic components or moving optical devices, but are not commonly used in current products. Similarly, if the LED display screen implements 2D/3D switching by using a method similar to that of adding a grating lens such as a lenticular lens grating and a slit grating to the front of the liquid crystal panel, similar shortcomings will also occur.

In CN203930226U, a naked-eye 3D display pixel unit is used to form a multi-view naked-eye 3D display device. Its optical package includes an optical guiding area and a light mixing area, and the light mixing area can mix the light emitted by the sub-pixel unit in the optical package through reflection, refraction or total reflection, and guide it to The optical guide area, the optical guide area and the sub-pixel unit correspond to each other, and the optical guide area can guide the light emitted by the sub-pixel unit so that it is deflected and converged to different directions, or blocked by a baffle The function is to guide the optical package out of the body, so that the pixel unit effectively emits the parallax images of the left and right eyes, and then reaches the eyes of the viewer, so that the human brain perceives the parallax images and fuses them into a stereoscopic image.

Because the naked-eye 3D display pixel unit is minimized to the device level, the 3D display pixel units can be arranged vertically and horizontally to form a display unit module or box according to the application and indoor/outdoor installation site needs, and multiple display unit modules can be spliced into different Large-area display screens with area size, convex arc, concave arc or free-form surface shape do not need to install optical lenses in parallel in front of the display screen, and are not limited by the size of the lens area at all, and can be freely expanded and seamlessly spliced to meet different shapes Display screen with size needed.

In addition, naked-eye 3D display pixel units can be matched with full-color LEDs, which are alternately arranged in adjacent rows and columns on the circuit substrate to form a display unit module, and assembled into a large-area screen. This system can switch between 2D and 3D image display modes by turning on or off the naked-eye 3D display pixel unit and full-color LED interactively. When the full-color LED is on, the naked-eye 3D display pixel unit is off, and the screen displays 2D images at this time. Conversely, when the naked-eye 3D display pixel units are turned on, the screen displays 3D images at this time.

Therefore, it is possible to play 2D content in the full-color LED area of the display screen and play naked-eye 3D content in the naked-eye 3D display pixel unit area at the same time. Or switch the 2D/3D display mode in real time on the full screen according to the program content. This kind of device needs to be composed of naked-eye 3D display pixel units and LED display devices adjacent to each other, but it is necessary to control the brightness and color consistency of two adjacent different components. In addition, because the naked-eye 3D display pixel units and LEDs are adjacently arranged to display 3D and 2D information respectively, the result will reduce the resolution of 2D and 3D images.

In view of this, how to make a naked-eye 3D display pixel unit capable of sending 2D information and 3D parallax images at the same time, and a high-resolution large-area display device that can be evenly arranged at a very small pitch, so that it has 2D or 3D images With the playback, the content display can be dynamically switched between functions, and it has the function of displaying 2D and 3D content in different areas of the display screen at the same time. This function is necessary when various 2D or 3D video contents are mixed and played, and it is also the deficiency of current glasses-type 3D and other existing stereoscopic display technologies.

As shown in the figure, in the first embodiment, the naked-eye 3D display pixel unit 1 of the present invention includes a pixel unit 110 , an optical mixing area 120 , an optical guiding area 130 and a control circuit (not shown).

In other words, the pixel unit 110 included in the naked eye 3D display pixel unit 1 of the present invention further includes a red light emitting unit 110a, a green light emitting unit 110b and a blue light emitting unit 110c, and a red light emitting unit 110a, a green light emitting unit 110b and a blue light emitting unit 110a. Each light emitting unit 110c includes a substrate 111 , a first electrode layer 112 , a first doped layer 113 , a second doped layer 114 and a plurality of second electrode layers 115 .

More specifically, the first electrode layer 112 is disposed on the substrate 111, the first doped layer 113 is disposed on the first electrode layer 112, the second doped layer 114 is disposed on the first doped layer 113, and the plurality of first doped layers The two electrode layers 115 are respectively disposed on the second doped layer 114 opposite to each other without being connected.

It is worth mentioning that the number of the second electrode layer 115 in the accompanying drawings of the present utility model is two as an example; in addition, when the first electrode layer 112 is an N-type electrode layer, the second electrode layer 115 is a P-type electrode layer. electrode layer; on the contrary, if the first electrode layer 112 is a P-type electrode layer, the second electrode layer 115 is an N-type electrode layer.

In other words, the optical mixing area 120 included in the naked-eye 3D display pixel unit 1 of the present invention is set on the pixel unit 110; and the optical guiding area 130 is set on the optical mixing area 120; Among them, the control circuit is used to electrically connect the pixel units 110, and control the pixel units 110 to project and form a corresponding 2D image or 3D image according to the 2D image signal or the 3D image signal.

Further, the present invention can apply lenticular lens grating, slit grating or other optical lens designs to the optical guide area 130 using microlens design and manufacturing techniques. In this embodiment, the optical guiding area 130 and the optical mixing area 120 can be made of different materials, or made of the same material, which can be adjusted according to the manufacturing process or depending on the display requirements. Adjust and design. The light-emitting surface of the optical guiding area 130 can be: a combination of plane, inclined surface, curved surface or double layers, such as: a combination structure such as a lenticular grating, a slit grating, or a double-layer lens design, to guide the light emitted by the pixel unit 110. The light is sent to different directions or is shielded by the baffle, and the light is emitted from the middle of the gap.

In more detail, when the control circuit sends a 2D image signal to the pixel unit 110, the pixel unit 110 will project light (2D image information) at a direct angle through the optical light mixing area 120 and the optical guide area 130; furthermore, the viewer's Both eyes will receive the 2D image information projected by the pixel unit 110 .

It is worth mentioning that when the control circuit transmits the 3D image signal to the pixel unit 110, the control circuit will alternately control the second electrode layers 115a, 115b to form corresponding electric fields with the first electrode layer 112, so that the pixel unit 110 can The light (3D image information) is respectively projected at two relative deflection angles in a staggered time sequence. Each 3D image information passes through the optical light mixing area 120 and the optical guide area 130 to the left eye and the right eye of the viewer, and the viewer passes through the Binocular parallax combines 3D image information in the brain to form a 3D image.

Furthermore, when the control circuit controls the second electrode layer 115a and the first electrode layer 112 to form an electric field at the first time point T1, the pixel unit 110 can project 3D image information according to the deflection angle corresponding to the second electrode layer 115a ( As shown in FIG. 2(a), the 3D image information is projected toward the left angle), and when the control circuit controls another second electrode layer 115b to form an electric field with the first electrode layer 112 at the second time point T2, the pixel unit 110 can project 3D image information according to another deflection angle corresponding to the second electrode layer 115b (as shown in FIG. 2( b ), 3D image information is projected toward the right angle).

From the above, it can be known that the pixel unit 110 of the present invention can project 3D image information from two different angles alternately in time sequence when displaying 3D images, because when one of the second electrode layers 115 and the first electrode layer 115 When an electric field is formed between the electrode layers 112, the projection angle of the pixel unit 110 will be biased towards the direction of the second electrode layer; therefore, it is only necessary to switch between different second electrode layers 115 and the first electrode layer 112 to form an electric field through the control circuit, The 3D image information can be projected at different angles interlacedly.

In addition, although the pixel unit 110 projects the 3D image information at a deflection angle when interlacedly projecting the 3D image information, in order to increase the offset angle of the projected 3D image information, the 3D image information needs to be further optically mixed.
