Description

COA type liquid crystal display
Technical Field
The invention relates to the technical field of display, in particular to a COA type liquid crystal display.
Background
Liquid Crystal Displays (LCDs) have many advantages such as thin body, power saving, no radiation, and are widely used, for example: liquid crystal televisions, mobile phones, Personal Digital Assistants (PDAs), digital cameras, computer screens, notebook computer screens, or the like, are dominant in the field of flat panel displays.
An active Thin Film Transistor-liquid crystal display (TFT-LCD) is the most common liquid crystal display in the mainstream market at present, and can be roughly divided into the following according to the driving manner of the liquid crystal: twisted Nematic (TN) or Super Twisted Nematic (STN) types, In-Plane Switching (IPS) types, and Vertical Alignment (VA) types. Among them, the VA mode lcd has a very high contrast ratio compared to other types of lcds, and has a very wide application in large-size displays such as tv.
Although TFT-LCDs have many advantages, there are many places where improvement is needed, for example, too small a viewing angle is one of the important problems affecting the display quality of TFT-LCDs. The display panel has a color shift phenomenon with a larger viewing angle, which is also called a large viewing angle color shift. The large viewing angle color shift is a phenomenon that when the liquid crystal display panel (especially, a VA-type liquid crystal display panel) is observed at a large angle, the color of the liquid crystal display panel is greatly shifted from that observed from the front, for example, when the liquid crystal display panel is observed at a normal viewing angle, but when the liquid crystal display panel is observed at a large viewing angle (60 °), the color of the liquid crystal display panel is abnormal, and the liquid crystal display panel is washed out by water.
At present, in order to solve the problem of color shift of the liquid crystal display panel with a large viewing angle, various designs for realizing Low color shift (Low color shift) of the liquid crystal display panel have been proposed, and for example, the 2D1G technology, the 3T technology, and the charge sharing (charging) technology are all common technologies for solving the problem of color shift of the VA-type liquid crystal display panel at present. The main common point of these designs is that each sub-pixel of the liquid crystal display panel is divided into a main (main) pixel area and a sub-pixel area, and then the difference of the liquid crystal molecule deflection angles of the main pixel area and the sub-pixel area is realized by various methods to improve the large viewing angle color cast. Among them, the 2D1G technology is to provide signals to the Main pixel area and Sub pixel area separately, thereby bringing the possibility of improving the display effect of large viewing angle by using different Gamma curves (Gamma curves). Both the 3T and Charge sharing technologies essentially divide a sub-pixel display area into two parts with different brightness, and adjust the gamma curve of oblique viewing by using the difference of oblique viewing brightness when different front viewing brightness is used.
Techniques based on the above principle are often achieved by capacitive coupling or multi-TFT control, where capacitive coupling based methods are widely used, but they also have some problems, such as: 1. the degree of capacitive coupling is different in different manufacturing processes, is influenced by the difficulty of adjusting the thickness and the size precision of the conductive layer in the manufacturing process and is difficult to adjust and control; 2. the sub-pixel voltage (Vsub) generated by coupling is not necessarily linear at different voltages, and Vsub is affected by the semiconductor and its process characteristics at different gray scales, and even if the same design is adopted, the improvement effect is different in different devices and processes; 3. by dividing the pixels into different regions and adopting different voltage driving modes, the aperture ratio of the LCD can be reduced, so that the transmittance of the display is reduced.
Generally, a liquid crystal display includes a housing, a liquid crystal panel disposed in the housing, and a Backlight Module (Backlight Module) disposed in the housing. The Liquid Crystal panel is mainly composed of a Thin film transistor Array (TFT Array) substrate, a Color Filter (CF) substrate, and a Liquid Crystal Layer (Liquid Crystal Layer) disposed between the two substrates, and has an operation principle of applying a driving voltage to the two glass substrates to control the rotation of Liquid Crystal molecules of the Liquid Crystal Layer, and refracting light of the backlight module to generate a picture. The CF substrate mainly includes a color resist layer for forming colored light by a color resist unit (R/G/B), and a Black Matrix (BM) for preventing light leakage at the edges of pixels.
The Color-filter-on-Array (COA) technology is an integrated technology for directly manufacturing a Color filter layer on an Array substrate, can effectively solve the problems of light leakage and the like caused by alignment deviation in a liquid crystal display device box aligning process, and can remarkably improve the display aperture ratio. In addition, the prior art proposes a technical scheme of designing a Black Matrix (BM) on a TFT array substrate (BM on array, BOA), so as to continuously reduce the difficulty of the color filter substrate side.

Detailed Description
To further illustrate the technical means and effects of the present invention, the following detailed description is given with reference to the preferred embodiments of the present invention and the accompanying drawings.
Referring to fig. 1, the present invention provides a COA type liquid crystal display, which includes an array substrate 1 and a transparent substrate 2 disposed opposite to each other, a color photoresist layer 3 disposed on a side of the array substrate 1 facing the transparent substrate 2, a black matrix layer 4 disposed between the color photoresist layer 3 and the transparent substrate 2, a liquid crystal layer 5 disposed between the array substrate 1 and the transparent substrate 2, and a backlight module 6 disposed below the array substrate 1.
Wherein, the color photoresist layer 3 includes at least two photoresist units 35 with different colors; each photoresist unit 35 corresponds to a sub-pixel structure; the light-blocking units 35 in the color light-blocking layer 3 are connected to each other.
The black matrix layer 4 has pixel openings 45 corresponding to the light resistance units 35 one by one; the black matrix layer 4 includes a plurality of black light-shielding bars 46, and the plurality of black light-shielding bars 46 surround the plurality of pixel openings 41; each black shading strip 46 is correspondingly located above the connection between two adjacent photoresist units 35.
It should be noted that, in the prior art, the connection between two adjacent photoresist units 35 in the color photoresist layer 3 may be stacked on each other, which may cause poor Liquid Crystal (LC) inversion at the edge of the pixel; in addition, under the influence of the fringe electric field of the pixel electrode or the common electrode on the array substrate 1, dark fringes often occur at the edge position of the pixel, and the inclination angle of the liquid crystal at the position in the liquid crystal layer 5 is deviated from the central area. This deviation often results in low front-view transmittance and high side-view transmittance in the relevant region. In addition, as can be seen from the optical path diagram of fig. 2, the transmission area of each sub-pixel in front view depends on the width L of the corresponding pixel opening 41, the light transmission area width in front view is L, and the light transmission area width of the sub-pixel in side view is L-d tan θ + σ, where d is the distance from the color resist layer 3 to the upper surface of the black matrix layer 4, θ is the side view angle, and σ is a revised parameter value, so that the ratio of the side view transmitted light intensity to the front view transmitted light intensity of the sub-pixel is 1- (d tan θ - σ)/L, when the black shading strip 46 is widened, the width L of the corresponding pixel opening 41 changes, the width L of the pixel opening 41 changes the transmission area of the corresponding sub-pixel, and it can be seen from the above formula that the ratio of the side view transmitted light intensity to the front view transmitted light intensity of the sub-pixel depends on the width L of the pixel opening 41 and the width L of the color resist layer 3 to the upper surface of the black matrix layer 4 A distance d. Therefore, within a certain range, increasing the width of the black mask 46 to decrease the width L of the corresponding pixel opening 41 can decrease the ratio of the side-view transmittance to the front-view transmittance of the corresponding sub-pixel.
Based on the above principle, the widths of the pixel openings 45 corresponding to the photoresist units 35 with at least two different colors are different, so as to improve the ratio of the side-view transmitted light intensity to the front-view transmitted light intensity of the corresponding sub-pixels, thereby improving the color shift of the viewing angle of the liquid crystal display panel.
Specifically, the color photoresist layer 3 includes three photoresist units 35 of different colors, namely a red photoresist unit 31 corresponding to a red sub-pixel, a green photoresist unit 32 corresponding to a green sub-pixel, and a blue photoresist unit 33 corresponding to a blue sub-pixel.
Specifically, the pixel openings 45 of the black matrix layer 4 respectively corresponding to the red, green and blue photoresist units 31, 32 and 33 are the first, second and third pixel openings 41, 42 and 43.
Specifically, for example, the conventional liquid crystal display panel generally has a problem of color shift in skin color viewing angle, and the reason for this is mainly that the luminance of the blue sub-pixel in oblique view is excessively large relative to the luminance of the red sub-pixel and the green sub-pixel. Then to ameliorate this problem, it is desirable to reduce the ratio of side-view transmitted light intensity to front-view transmitted light intensity for the blue sub-pixel.
Therefore, in the embodiment of the present invention, the width of the third pixel opening 43 corresponding to the blue sub-pixel is preferably smaller than the width of the first pixel opening 41 and the width of the second pixel opening 42. The ratio of the side-view transmitted light intensity and the front-view transmitted light intensity of the blue sub-pixel is reduced, and the problem of visual angle color cast of the liquid crystal display panel is further improved.
Specifically, the width of the third pixel opening 43 is less than 92% of the width of the first pixel opening 41; the width of the third pixel opening 43 is less than 92% of the width of the second pixel opening 42.
Specifically, the width of the black light-shielding bar 46 is 10 to 35 μm, and the width of the pixel opening 41 is 50 to 100 μm.
Specifically, the present invention may also adopt a BOA design, where the black matrix layer 4 is disposed on the color photoresist layer 3, and the liquid crystal layer 5 is disposed between the black matrix layer 4 and the transparent substrate 2. Or,
the black matrix layer 4 is arranged on one side of the transparent substrate 2 facing the array substrate 1, and the liquid crystal layer 5 is arranged between the black matrix layer 4 and the array substrate 1.
The COA type liquid crystal display has at least two different colors of light resistance units 35 corresponding to different pixel openings 45, and can reduce the ratio of side-view transmission light intensity and front-view transmission light intensity of corresponding sub-pixels by reducing the width of the pixel openings 45.
In summary, the present invention provides a COA type liquid crystal display, which includes an array substrate, a transparent substrate, a color photoresist layer and a black matrix layer, wherein the color photoresist layer includes at least two photoresist units with different colors, the black matrix layer has pixel openings corresponding to the photoresist units one by one, and the widths of the pixel openings corresponding to the at least two photoresist units with different colors are different.
As described above, it will be apparent to those skilled in the art that other various changes and modifications may be made based on the technical solution and concept of the present invention, and all such changes and modifications are intended to fall within the scope of the appended claims.
