As shown in fig. 1, in the conventional VR display device, the display panel includes an array substrate and a color filter substrate, the array substrate includes a first substrate 111 and metal traces 112 disposed on the first substrate 111, the color filter substrate includes a second substrate 121, and a color resist layer and a black matrix layer 122 disposed on the second substrate 121, the color resist layer includes a red color resist 122a, a green color resist 122b and a blue color resist 122c, and after light is emitted from the backlight module and transmitted between the metal traces 112 passing through the array substrate, the light passes through the liquid crystal layer and the color filter substrate to be displayed, but for an edge area of the display panel, due to a larger exit angle, liquid crystals in a blue light-transmitting area corresponding to a blue sub-pixel are deflected, so that the light 13 reaches the green pixel, and as can be seen from fig. 1, the light 13 is emitted from the green color resist 122b, and similarly, light of other pixels is also disordered, resulting in the occurrence of light mixing and thus display unevenness. To solve this problem, the prior art proposes the technical solution shown in fig. 2, by increasing the width of the black matrix, the original light irradiated to the green color resistor 122b is shielded by the black matrix 122, and the light cannot be emitted, and at this time, although the problem of partial light mixing is solved, due to the loss of light and aperture ratio, the aperture ratio of the display panel is small, and the light with a large viewing angle cannot be emitted. Therefore, the prior VR display device has the technical problem of uneven display caused by light mixing at a large visual angle.
In view of the above technical problems, embodiments of the present application provide a liquid crystal display panel and a liquid crystal display device to alleviate the above technical problems.
As shown in fig. 3, an embodiment of the present application provides a liquid crystal display panel, where the liquid crystal display panel 2 includes:
the array substrate 21 comprises non-light-transmitting regions 251 corresponding to the metal wires 212 and light-transmitting regions 252 arranged between the non-light-transmitting regions 251;
the color film substrate 23 is arranged opposite to the array substrate 21, and comprises a color resistance layer 232 and a black matrix layer 233, wherein the black matrix layer 233 is arranged between the color resistance layers 232;
the liquid crystal layer 22 is arranged between the array substrate 21 and the color film substrate 23;
at least in the edge area 242 of the liquid crystal display panel 2, at least some color resists in the color resist layer 232 are disposed in a staggered manner with respect to the corresponding light-transmitting areas 252.
The embodiment of the application provides a liquid crystal display panel, this liquid crystal display panel is through at least at marginal zone, make at least partial colour drag in the colour drag layer and the setting of corresponding printing opacity district dislocation, then when liquid crystal display panel sent the light at large visual angle, because colour drag and the setting of corresponding printing opacity district dislocation for light can jet out from the colour drag, and can not because the too big dispersion of light angle is to adjacent colour drag, reduce liquid crystal display panel's marginal mixed light, improve display panel's demonstration homogeneity.
It should be noted that the color resistors and the corresponding light-transmitting areas in the color resistor layer refer to that light rays pass through the light-transmitting areas on the array substrate first and then pass through the corresponding color resistors when passing through the display panel, and in this process, each light-transmitting area has a corresponding color resistor, for example, the light-transmitting area corresponding to the blue sub-pixel corresponds to the blue color resistor, the display panel displays normally only when the light rays normally pass through the light-transmitting areas and the blue color resistors corresponding to the blue sub-pixel, and when the light rays pass through the green color resistors from the light-transmitting areas corresponding to the blue display, the color mixture problem of the existing display device may exist, and therefore, the color resistors and the corresponding light-transmitting areas in the color resistor layer refer to the light-transmitting areas and the corresponding color resistors corresponding to the same pixel.
The color resistance in the color resistance layer and the corresponding light transmission area are arranged in a staggered way, that is, the color resistance of the color resistance layer and the corresponding light transmission area are not arranged correspondingly, for example, in general arrangement, the areas of the color resists corresponding to the light-transmitting region and the color resist layer are equal or have a certain area difference, but the light-transmitting region and the color resist layer are symmetrically arranged correspondingly, in the embodiment of the application, the color resistors and the light-transmitting areas are staggered, so that the color resistors at least partially do not correspond to the corresponding light-transmitting areas, and the color resistors and the corresponding light-transmitting regions are asymmetrically arranged, taking the liquid crystal display panel shown in FIG. 3 as an example, it can be seen that the overlapping area 26 of the light-transmitting region 252 corresponding to the blue sub-pixel and the blue color filter 232c is smaller than the area of the light-transmitting region 252, and is smaller than the area of the blue color resistor 232c, and the light-transmitting region 252 corresponding to the blue sub-pixel is asymmetrically arranged with the blue color resistor 232c, i.e. the light-transmitting region corresponding to the blue sub-pixel and the blue color resistor are arranged in a staggered manner.
In one embodiment, the width of at least one of the color resistance layer and the black matrix layer is gradually changed, and the size of the overlapping area of the color resistance in the color resistance layer and the corresponding light-transmitting area is gradually changed. Through making the width gradual change of at least one in colour drag layer and the black matrix layer, then can be so that when colour drag and the printing opacity district in the colour drag layer set up, because the width gradual change of colour drag layer and black matrix layer, the colour drag changes with the overlapping area who corresponds the printing opacity district, the colour drag misplaces with the printing opacity district that corresponds, and the colour drag gradually changes with the area of the overlapping area of the printing opacity district that corresponds, can make the overlapping area change of colour drag and the printing opacity district that corresponds along with the change of angle, thereby make the light that sees through the printing opacity district can reach corresponding colour drag.
The problem of increasing the width of the black matrix may result in a decrease in the aperture ratio of the display panel. In one embodiment, as shown in fig. 3, the width of the color resistor in the color resistor layer 232 is not changed from the middle region 241 of the liquid crystal display panel to the edge region 242 of the liquid crystal display panel, and the width of the black matrix in the black matrix layer 233 is sequentially increased (for example, the width of the black matrix is changed from L1 to L2, and L1 is smaller than L2). Through making the width of the color resistance in the color resistance layer unchangeable, the aperture opening ratio of the liquid crystal display panel is unchangeable, and the aperture opening ratios in different areas are equal, and the width of the black matrix in the black matrix layer is increased in sequence, so that the color resistance and the corresponding light transmission area are arranged in a staggered mode, and along with the increase of the visual angle, the staggered degree of the color resistance and the corresponding light transmission area is increased, the light rays with large visual angles are normally emitted, and color mixing is avoided.
Specifically, as shown in fig. 3, it can be seen that the divergence angle of the light is larger in the large viewing angle direction, but in the embodiment of the present application, the color resistors and the corresponding light-transmitting regions are arranged in a staggered manner, so that the light can be normally diverged, for example, the light emitted from the light-transmitting region 252 corresponding to the green pixel in fig. 3 normally passes through the green color resistor 232b, so that the light is normally diverged, and the problem of light mixing cannot occur.
In one embodiment, the width of the color resistor in the color resistor layer is constant from the middle area of the liquid crystal display panel to the edge area of the liquid crystal display panel, and the width of the black matrix in the black matrix layer is reduced in sequence. The width of the black matrix is reduced in sequence, so that the color resistance of the color resistance layer is staggered with the corresponding light-transmitting area, and the light can irradiate the corresponding color resistance layer to avoid color mixing.
In one embodiment, as shown in fig. 4, from the middle region 241 of the liquid crystal display panel to the edge region 242 of the liquid crystal display panel, the width of the color resistor in the color resistor layer 232 is not changed, the width of the black matrix in the black matrix layer 233 is sequentially decreased (for example, the width of the black matrix is changed from L3 to L4, and L3 is greater than L4), and the width L3 of the black matrix 233 in the middle region 241 of the liquid crystal display panel is greater than the width L5 of the non-light-transmission region 251. The width of the black matrix is reduced in sequence, the width of the black matrix in the middle area is larger than that of the non-light-transmitting area, the color resistance is staggered with the corresponding light-transmitting area, the color resistance is deviated to the edge area relative to the corresponding light-transmitting area, and when light at a large visual angle is dispersed, the corresponding color resistance can be dispersed without the color mixing problem.
In one embodiment, the width of the color resistor in the color resistor layer is unchanged from the middle area of the liquid crystal display panel to the edge area of the liquid crystal display panel, the width of the black matrix in the black matrix layer is sequentially reduced, and the width of the black matrix in the middle area of the liquid crystal display panel is smaller than or equal to the width of the non-light-transmission area. When setting up the black matrix, can also make the width of black matrix be less than or equal to the width of non-printing opacity district for light can disperse to corresponding colour resistance to the middle zone, avoids light colour mixture to appear.
For example, when designing the red color resists, the green color resists, and the blue color resists, the sizes of the red color resists, the green color resists, and the blue color resists are different, and in this case, the width of the color resists is not changed, which means that the widths of the red color resists are equal, the widths of the green color resists are equal, and the widths of the blue color resists are equal, from the middle region of the liquid crystal display panel to the edge region of the liquid crystal display panel.
It should be noted that, in order not to change the size of the display panel, when the width of the black matrix is changed, the width of the black matrix may gradually change, and meanwhile, the overall width of the black matrix is made to be consistent with the original width, so that the size of the display panel is not increased, but the width of the black matrix may also be increased by increasing the size of the display panel, which is not limited in the embodiment of the present application.
In one embodiment, as shown in fig. 5, the width of the black matrix in the black matrix layer 233 is constant from the middle region 241 of the lcd panel to the edge region 242 of the lcd panel, and the widths of the color resistors in the color resistor layer 232 are sequentially increased (e.g., the width L7 of the blue color resistor 232c is greater than the width L6 of the red color resistor 232 a). The width of the black matrix is unchanged, the width of the color resistor is increased in sequence, the color resistor and the corresponding light-transmitting area are arranged in a staggered mode, the width of the color resistor is increased in sequence, the quantity of light which can pass is increased in the direction of a large visual angle, the brightness of the large visual angle is improved, and therefore the display uniformity of the liquid crystal display panel is improved.
Specifically, when the widths of the color resistors in the color resist layer are sequentially increased, the widths of the different color resistors of the same pixel may be sequentially increased, for example, as shown in fig. 5, the widths of the red color resistor, the green color resistor, and the blue color resistor of the same pixel are sequentially increased, and the widths of the color resistors are sequentially increased based on a single color resistor, so that the widths of the color resistors in the color resist layer are sequentially increased, the brightness of a large viewing angle is improved, and the display uniformity of the liquid crystal display panel is improved.
Specifically, when the widths of the color resistors in the color resistor layer are sequentially increased, the widths of the color resistors may be sequentially increased based on a single pixel, for example, if the single pixel includes a red color resistor, a green color resistor, and a blue color resistor, the size of the color resistor of the same pixel is not changed, and by increasing the widths of the color resistors of adjacent pixels, even if the variation of the widths of the color resistors of the adjacent pixels is the same, the widths of the color resistors in the color resistor layer are sequentially increased, at this time, the sizes of the red color resistor, the green color resistor, and the blue color resistor in the single pixel may have a state where the width of the green color resistor is smaller than the width of the red color resistor, but the widths of the color resistors in the color resistor layer as a whole are still sequentially increased.
Specifically, when the widths of the color resistors in the color resistance layer are sequentially increased, the widths of the color resistors can be sequentially increased by using the color resistors of the same color as a reference, for example, if each pixel includes a red color resistor, a green color resistor, and a blue color resistor, the widths of the red color resistors can be sequentially increased, the widths of the green color resistors can be sequentially increased, and the widths of the blue color resistors can be sequentially increased, so that the widths of the color resistors in the color resistance layer are sequentially increased.
In one embodiment, as shown in fig. 6, the width of the black matrix in the black matrix layer 233 is constant from the middle region 241 of the lcd panel to the edge region 242 of the lcd panel, and the widths of the color resistors in the color resistor layer 232 are sequentially decreased (e.g., the width L9 of the blue color resistor 232c is smaller than the width L8 of the red color resistor 232 a). The width of the color resistor on the color resistor layer is reduced in sequence, so that the color resistor and the corresponding light-transmitting area are arranged in a staggered mode, light can penetrate through the corresponding color resistor, and color mixing is avoided.
Specifically, the width of the color resistance layer in the middle area of the liquid crystal display panel is greater than the width of the light-transmitting area. The width of the color resistance layer in the middle area of the liquid crystal display panel is larger than that of the light transmission area, so that the aperture opening ratio of the display panel can be kept unchanged along with the reduction of the width of the color resistance layer, and the aperture opening ratio is prevented from being reduced while light mixing is avoided.
Specifically, the width of the color resistor layer in the middle area of the liquid crystal display panel is smaller than or equal to the width of the light-transmitting area. The width of the color resistor layer in the middle area is smaller than or equal to the width of the light transmission area, so that the color resistor and the corresponding light transmission area are arranged in a staggered mode, and the problem of light mixing of the liquid crystal display panel is avoided.
Specifically, the manner in which the widths of the color resistors are sequentially decreased is similar to the manner in which the widths of the color resistors are sequentially increased described in the above embodiments, and details are not described here again.
It should be noted that, in the above embodiments, the width of the color resistor is not changed, the width of the black matrix is gradually changed, or the width of the color resistor is gradually changed, and the width of the black matrix is not changed, but the embodiments of the present application are not limited thereto, for example, when the color resistor and the corresponding light-transmitting area are dislocated, light cannot pass through the liquid crystal to reach the color resistor, and at this time, light can reach the color resistor by adjusting the color resistor and the black matrix simultaneously, so as to avoid light mixing, and the liquid crystal display panel can normally display.
It should be noted that, although the foregoing embodiments have been described in detail by taking the example that the widths of the color resistors or the black matrixes gradually change, the embodiments of the present application are not limited thereto, for example, when the color resistors and the corresponding light-transmitting regions are misaligned, light cannot pass through the liquid crystal to reach the color resistors, and the width of a certain color resistor or black matrix can be adjusted to avoid light loss.
The problem that changing the color resistance and the width of the black matrix may cause the size of the liquid crystal display panel to change. In one embodiment, as shown in fig. 7 and 8, from the middle region 241 of the lcd panel to the edge region 242 of the lcd panel, the area of the overlapping region 26 of the color resist layer 232 and the corresponding light-transmitting region 252 is equal, and the overlapping region 26 of the color resist layer 232 and the corresponding light-transmitting region 252 is located on the left side of the color resist layer 232 (e.g., the overlapping region 26 of the blue color resist 232c and the light-transmitting region 252 in fig. 8 is located on the left side of the blue color resist 232 c) or on the right side of the color resist layer 232 (e.g., the overlapping region 26 of the blue color resist 232c and the light-transmitting region 252 in fig. 7 is located on the right side of the blue color resist 232 c). Through making the overlap area that the colour resistance layer and the printing opacity district that corresponds equal for printing opacity district or the whole skew of colour resistance layer, thereby make colour resistance and the printing opacity district dislocation set that corresponds, at the divergent in-process of light, avoid producing the mixed light, improve the homogeneity that shows.
Specifically, when the overlapping area of the color resistor and the corresponding light-transmitting area is located on the left side of the color resistor layer, light can be diffused into the corresponding color resistor when being diffused to a large visual angle, light mixing is avoided, and the brightness of the large visual angle is improved.
Specifically, when the overlapping area of the color resistor and the corresponding light-transmitting area is located on the right side of the color resistor layer, light can be diffused into the corresponding color resistor, and light mixing is avoided.
Specifically, in the above embodiment, the color resistors and the corresponding light-transmitting areas are entirely shifted, but the embodiment of the present invention is not limited thereto, for example, as can be seen from fig. 7 and 8, taking the edge area on the right as an example, when the overlapping area of the color resistors and the corresponding light-transmitting areas is located on the right side of the color resistors, the light will be diffused toward the middle area, so that in the edge area on the left side, the overlapping area of the color resistors and the corresponding light-transmitting areas is located on the right side of the color resistors, and in the edge area on the right side, the overlapping area of the color resistors and the corresponding light-transmitting areas is located on the left side of the color resistors, so that the light can be diffused with a large viewing angle, and in the middle area, the middle area of the liquid crystal display panel can be normally displayed by changing the widths of the color resistors and the black matrix.
In one embodiment, as shown in fig. 9, the widths of the light-transmitting regions 252 sequentially increase from the middle region 241 of the liquid crystal display panel to the edge region 242 of the liquid crystal display panel (e.g., the width K1 of one light-transmitting region is smaller than the width K2 of another light-transmitting region in fig. 9). The width through making the printing opacity district increases in proper order for the look hinders with the printing opacity district dislocation set that corresponds, and because the width in printing opacity district increases in proper order, to the light at big visual angle, can pass the printing opacity district and reach the look that corresponds and hinder, avoids the colour mixture, and improves the luminance at big visual angle, improves and shows the homogeneity.
Specifically, the width of the light transmission area is sequentially increased, the width of the light transmission area can be increased through the width without changing the metal wiring, the width of the light transmission area is increased through increasing the distance between the metal wiring, therefore, the impedance of the metal wiring is not changed, and the color resistance and the corresponding light transmission area are arranged in a staggered mode.
Specifically, when the width of the light-transmitting area is increased in sequence and the width of the metal wiring is not changed, the width of the light-transmitting area in the middle area can be smaller than the width of the color resistor, so that the size of the liquid crystal display panel can not be increased when the width of the light-transmitting area is increased in sequence.
In one embodiment, as shown in fig. 9, the widths of the metal traces 212 are sequentially decreased from the middle region 241 of the lcd panel to the edge region 242 of the lcd panel (for example, the width K3 of one metal trace is greater than the width K4 of another metal trace in fig. 9). The width of walking the line through making the metal reduces in proper order for when the width in increase printing opacity district, can not increase the size of liquid crystal display panel, and can make light see through and reach the colour resistance that corresponds behind the printing opacity district, avoid appearing mixing the light, improve and show the homogeneity.
Specifically, the width of the metal trace in the middle area may be smaller than or equal to the width of the corresponding black matrix, so that the size of the liquid crystal display panel may not be changed when the width of the metal trace is sequentially reduced. The width of the metal wire in the middle area can be larger than that of the corresponding black matrix, so that when the width of the metal wire is reduced, the impedance of the metal wire can be prevented from being increased.
In one embodiment, as shown in fig. 10, the widths of the light-transmitting regions 252 decrease sequentially from the middle region 241 of the liquid crystal display panel to the edge region 242 of the liquid crystal display panel (e.g., the width K6 of one light-transmitting region is greater than the width K5 of another light-transmitting region in fig. 10). The width through making the printing opacity district reduces in proper order for printing opacity district and the color that corresponds hinder dislocation set, make light can disperse to the color that corresponds hinder after passing the printing opacity district, avoid appearing mixing of light, improve and show the homogeneity.
Specifically, the width of the light transmission area is sequentially reduced, the width of the light transmission area can be increased by not changing the width of the metal wiring, and the width of the light transmission area is increased by reducing the distance between the metal wiring, so that the impedance of the metal wiring is not changed, and the color resistance and the corresponding light transmission area are arranged in a staggered mode.
Specifically, when the width of the light-transmitting area is sequentially reduced and the width of the metal wiring is not changed, the width of the light-transmitting area in the middle area can be larger than the width of the color resistor, so that the size of the liquid crystal display panel can not be changed when the width of the light-transmitting area is sequentially reduced.
In one embodiment, as shown in fig. 10, the widths of the metal traces 212 are sequentially increased from the middle region 241 of the lcd panel to the edge region 242 of the lcd panel (for example, the width K8 of one metal trace is smaller than the width K9 of another metal trace in fig. 10). The width of walking the line through making the metal increases in proper order for when reducing the width in printing opacity district, can not change the liquid crystal display panel size, and can make light see through and reach the colour resistance that corresponds behind the printing opacity district, avoid appearing mixing light, improve and show the homogeneity.
Specifically, the width of the metal wiring is sequentially increased, so that the width of the metal wiring in the middle area is smaller than the width of the corresponding black matrix, and the size of the liquid crystal display panel can not be changed by increasing the width of the metal wiring. The metal routing in the middle area can be equal to or larger than the width of the black matrix, and the impedance of the metal routing is prevented from being increased.
In one embodiment, the width of the color resistor in the color resistor layer is constant from the middle area of the liquid crystal display panel to the edge area of the liquid crystal display panel, and the width of the black matrix in the black matrix layer is constant. When the width of the light-transmitting area and/or the width of the metal wire are/is changed to enable the light-transmitting area and the corresponding color resistors to be arranged in a staggered mode, the sizes of the color resistors and the black matrix can be unchanged, and therefore the aperture opening ratio of the liquid crystal display panel is unchanged.
Specifically, when the color resistor and the light-transmitting area are arranged in a staggered manner, the offset of the black matrix can be as follows: the black matrix is shifted by the height of the liquid crystal layer tan (viewing angle). Therefore, light can penetrate through the color resistor and the corresponding light-transmitting area, and color mixing is avoided.
It should be noted that, the above embodiments respectively describe the color resistors, the black matrix, the metal wires, and the light-transmitting regions in detail, but the embodiments of the present application do not limit a certain feature to only belong to a specific embodiment, for example, when the width of the color resistor in the color resistor layer is unchanged from the middle region of the liquid crystal display panel to the edge region of the liquid crystal display panel, and the width of the black matrix in the black matrix layer is sequentially increased, the size of the metal wires may be unchanged, and the size of the light-transmitting region may be unchanged, but the size of the metal wires and the size of the light-transmitting region may also be changed, so that light can pass through the light-transmitting region and the corresponding color resistors, thereby avoiding light mixing. Similarly, when the metal wires and/or the metal wires are described, the corresponding color resistors and the black matrix can be changed or not changed, so that light can pass through the light-transmitting area and the corresponding color resistors, mixed light is avoided, and the description is omitted.
It should be noted that, in the above embodiments, the metal trace refers to the light shielding portion of the light-transmitting region on the side of the array substrate, the metal trace is not limited to a trace, and may also be an electrode, for example, the metal trace includes a gate, a source, a drain, a scan line, and the like. Therefore, when the size of the metal trace is changed, the width of the area that is actually shielded from light is changed without actually limiting to change a certain element, and details thereof are not repeated herein.
It should be noted that, in the drawings, there is a case where the color resistance does not correspond to the liquid crystal, which is to specifically describe the change of the color resistance, the black matrix, the light-transmitting area and the metal wiring, but in an actual design, if the color resistance does not correspond to the liquid crystal, all light rays cannot be transmitted, the color resistance is not set to be not corresponding to the liquid crystal, if the color resistance does not correspond to the liquid crystal, the light rays can still be transmitted, the positions of the color resistance and the liquid crystal can be set according to requirements, and details are not described herein.
It should be noted that, after the color resistor and the light-transmitting region are dislocated, light rays at a position right above the light-transmitting region can be shielded, but because the optical lens cannot use the light rays, the light rays are easy to generate stray light to enter human eyes, and the contrast is reduced, so that the display effect can be improved by shielding the light rays.
It should be noted that, in the above embodiments, only the color resistance layer, the black matrix layer, and the metal traces are described in detail. However, it can be understood that the liquid crystal display panel includes a plurality of film layers, for example, in fig. 3, the array substrate further includes a first substrate 211, the color filter substrate further includes a second substrate 231, and the color resist layer 232 includes a red color resist 232a, a green color resist 232b, and a blue color resist 232 c.
