Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
fig. 1 is a schematic structural diagram of a display panel 0 in a narrow-frame display device provided in the related art, and as shown in fig. 1, the display panel 0 includes a color film substrate 01 and an array substrate 02 formed in a box-to-box manner, and a liquid crystal 03 located between the color film substrate 01 and the array substrate 02. In the display panel 0, the distance between the color filter substrate 01 and the array substrate 02 in the edge area a is greater than the distance between the color filter substrate 01 and the array substrate 02 in the central area B, so that the box thickness of the edge area a of the display panel 0 is greater than that of the central area B. Further, the color film substrate 01 may include a substrate 011 and a plurality of color filter units 012 formed on the substrate 011 and arranged in an array, where each color filter unit 012 includes a red color filter block R, a green color filter block G, and a blue color filter block B. And the thicknesses of all the color blocks in the display panel 0 are equal.
However, since the larger the cell thickness of the display panel is, the greater the light transmittance of the display panel is, the luminance of the light emitted from the edge area a of the display panel 0 is higher, and the luminance of the light emitted from the central area B is lower, which affects the display effect of the display panel. And because the absorption rate of each film layer in the display panel to the red light allowed to pass through by the red light color blocking block R is small, and the absorption rates of the green light allowed to pass through by the green light color blocking block G and the blue light allowed to pass through by the blue light color blocking block B are large, when the white light emitted by the backlight passes through the edge area a of the display panel 0, more red light can pass through, and less green light and blue light can pass through, so that the edge area a of the display panel 0 is yellow.
As shown in fig. 2, an embodiment of the present invention provides a display panel 1, where the display panel 1 may include: the color filter substrate 11 may include a substrate 111 and a plurality of color resist units 112 formed on the substrate 111 in an array arrangement, and each color resist unit 112 may include at least two color resist blocks.
the color resistance units 112 include at least one color resistance adjusting unit X, and in the color resistance adjusting unit X: the thickness of the first color block is larger than that of the second color block; the absorption rate of light with a wavelength corresponding to the first color resist block is less than that of light with a wavelength corresponding to the second color resist block, and it should be noted that the predetermined film on the display panel 1 may be a film on the display panel different from a film on which a plurality of color resist units are located (i.e., a color film formed on the substrate 111), such as the substrate 111, the array substrate 12, a liquid crystal (not shown in fig. 2), and a polarizer (not shown in fig. 2).
to sum up, in the color resistance adjusting unit in the color filter substrate of the display panel, the thickness of the first color resist block is greater than that of the second color resist block, and the absorption rate of the hierarchical structure formed by overlapping all the preset films on the display panel to the light with the wavelength corresponding to the first color resist block is smaller than that to the light with the wavelength corresponding to the second color resist block, that is, when the absorption rate of the hierarchical structure to the light with the wavelength corresponding to the first color resist block is different from that to the light with the color corresponding to the second color resist block, the thickness of the color resist block is adjusted (that is, the absorption rate of the color resist block to the light is adjusted) so that the absorption rate of the display panel to the light with the wavelength corresponding to the first color resist block is the same as that to the light with the color corresponding to the second color resist block, and thus the light flux of the area corresponding to the first color resist block on the display panel is the same as the light flux of the area corresponding to the second color resist, the yellowing phenomenon of the display panel is improved, so the display effect of the display panel is improved.
The first color block may allow light with a wavelength corresponding to the first color block to pass through, and the second color block may allow light with a wavelength corresponding to the second color block to pass through. The first color block may include a red color block R, which may allow red light to pass through; the second color block may include a green color block G that may allow green light to pass therethrough and a blue color block B that may allow blue light to pass therethrough.
Optionally, with continued reference to fig. 2, the box thickness of the edge region P of the display panel 1 may be greater than the box thickness of the central region Q of the display panel 1, and the at least one color resistance adjusting unit X may be located in the edge region P of the display panel 1. For example, the box thickness of the display panel 1 may be a distance between the color filter substrate 11 and the array substrate 12, and the distance between the color filter substrate 11 and the array substrate 12 in the edge region P is greater than that between the color filter substrate 11 and the array substrate 12 in the central region Q. That is, when the display panel 1 is a narrow-frame display panel, the box thickness of the edge region P of the display panel 1 is greater than that of the central region Q, and the yellowing phenomenon of the edge region P of the display panel 1 is more obvious, and the at least one color resistance adjusting unit X is disposed in the edge region P of the display panel 1, so that the yellowing phenomenon of the edge region P can be effectively eliminated.
Further, the thickness of each color resist block in the color resist unit 112 of the central region Q may be equal. The thickness of the second color resist block may be greater than the thickness of each color resist block in the color resist unit 112 of the central region Q of the display panel 1. For example, each color resistance unit on the color film substrate 11 includes a red color resistance block R, a green color resistance block G, and a blue color resistance block B, and the thicknesses of the red color resistance block R, the green color resistance block G, and the blue color resistance block B in the central region Q may be equal to each other and are all smaller than the thickness of the first color resistance block or the thickness of the second color resistance block in the edge region P, that is, in the color resistance blocks on the color film substrate 11, the thickness of the red color resistance block R in the edge region P is the largest, and the thickness of the green color resistance block G in the edge region P may be equal to the thickness of the blue color resistance block B in the edge region P, and are both smaller than the thickness of the red color resistance block R in the edge region P and are both larger than the thickness of any color resistance block in the central region Q.
In the related art, the hierarchical structure composed of all the preset film layers in the display panel has a small absorption rate to red light and a large absorption rate to green light and blue light, so that the display panel in the related art is yellow. In the embodiment of the invention, the thickness of the first color blocking block is larger than that of the second color blocking block, the absorptivity of the first color blocking block to red light is larger than that of the second color blocking block to blue light or green light, and when the absorptivity of the hierarchical structure to red light, blue light and green light is different, the absorptivity of the whole display panel to red light, blue light and green light tends to be the same by adjusting the absorptivity of the color blocking blocks to red light, blue light and green light, so that the yellow phenomenon of the display panel is reduced, and the display effect of the display panel is improved.
Because the light transmittance of the edge area of the narrow-frame display panel is greater than that of the central area, in the related art, the brightness of the edge area of the display panel is greater than that of the central area, and the proportion of the red light, the green light and the blue light in the transmitted light changes along with the increase of the box thickness, wherein the proportion of the red light in the transmitted light increases along with the increase of the box thickness, so that the yellowing phenomenon of the edge area of the display panel is obvious; in the embodiment of the invention, the thickness of all the color blocks in the edge area is set to be larger than that of each color block in the central area, namely, the luminous flux of the edge area of the display panel is reduced, the luminous flux of the central area of the display panel is improved, the brightness of the edge area and the brightness of the central area are effectively adjusted, the brightness of the edge area of the display panel and the brightness of the central area tend to be consistent, the thickness of the red color block in the edge area is larger than that of the red color block in the central area, the proportion of red light in transmitted light in the edge area is greatly reduced, the phenomenon of yellowing of the edge of the display panel is weakened, and the display effect of the display panel is improved.
In addition, in the color resistance units arranged in the central area in the embodiment of the present invention, the thicknesses of the color resistance blocks are all equal, and in practical applications, in order to better improve the display effect of the display panel, the thicknesses of the red color resistance block in the color resistance units arranged in the central area may also be set to be greater than the thicknesses of the blue color resistance block and the green color resistance block, and less than the thicknesses of the blue color resistance blocks arranged in the edge area.
to sum up, in the color resistance adjusting unit in the color filter substrate of the display panel, the thickness of the first color resist block is greater than that of the second color resist block, and the absorption rate of the hierarchical structure formed by overlapping all the preset films on the display panel to the light with the wavelength corresponding to the first color resist block is smaller than that to the light with the wavelength corresponding to the second color resist block, that is, when the absorption rate of the hierarchical structure to the light with the wavelength corresponding to the first color resist block is different from that to the light with the color corresponding to the second color resist block, the thickness of the color resist block is adjusted (that is, the absorption rate of the color resist block to the light is adjusted) so that the absorption rate of the display panel to the light with the wavelength corresponding to the first color resist block is the same as that to the light with the color corresponding to the second color resist block, and thus the light flux of the area corresponding to the first color resist block on the display panel is the same as the light flux of the area corresponding to the second color resist, the yellowing phenomenon of the display panel is improved, so the display effect of the display panel is improved.
As shown in fig. 3, an embodiment of the present invention provides a method for manufacturing a display panel, which may be used to manufacture the display panel 1 shown in fig. 2, and the method for manufacturing the display panel may include:
Step 301, forming an array substrate;
step 302, forming a plurality of color resistance units arranged in an array on a substrate to obtain a color film substrate, where each color resistance unit includes at least two color resistance blocks, the plurality of color resistance units includes at least one color resistance adjusting unit, and in the color resistance adjusting unit: the thickness of the first color block is larger than that of the second color block;
Step 303, performing box-to-box forming on the color film substrate and the array substrate to obtain a display panel, wherein a hierarchical structure is formed by overlapping all preset film layers on the display panel, the absorption rate of light with a wavelength corresponding to the first color resist block is smaller than that of light with a wavelength corresponding to the second color resist block, and the preset film layers are different from the film layers where the plurality of color resist units are located.
In summary, in the display panel manufactured by the method, in the color resistance adjusting unit in the color filter substrate, the thickness of the first color resist block is greater than that of the second color resist block, and the absorption rate of the light with the wavelength corresponding to the first color resist block by the hierarchical structure formed by overlapping all the predetermined films on the display panel is smaller than that of the light with the color corresponding to the second color resist block, that is, when the absorption rate of the light with the wavelength corresponding to the first color resist block is different from that of the light with the color corresponding to the second color resist block by the hierarchical structure, the thickness of the color resist block is adjusted (that is, the absorption rate of the color resist block to the light is adjusted) so that the absorption rate of the light with the wavelength corresponding to the first color resist block by the display panel is the same as that of the light with the color corresponding to the second color resist block, and thus the light flux of the area corresponding to the first color resist block on the display panel is the same as that of the light flux of the area corresponding to the second color resist block, the yellowing phenomenon of the display panel is improved, so the display effect of the display panel is improved.
In the embodiment of the present invention, when step 302 is executed, a first gray mask and a second gray mask need to be used, where the first gray mask may include: the non-shielding area is used for allowing all light rays to pass through and the second shielding area is used for allowing part of light rays to pass through, and the non-shielding area corresponds to the area on the substrate base plate, where the first color block is formed; the second gray mask may include: the first shielding area that partial light can pass through to and the third shielding area that partial light can pass through, first shielding area corresponds with the area that forms the second colour and hinders the piece on the substrate base plate. The second shielding region and the third shielding region both correspond to the central region of the substrate base plate, the light transmittance of the first shielding region is simultaneously greater than the light transmittance of the second shielding region and the light transmittance of the third shielding region, and the light transmittance of the second shielding region is equal to the light transmittance of the third shielding region.
the first color block may allow light with a wavelength corresponding to the first color block to pass through, and the second color block may allow light with a wavelength corresponding to the second color block to pass through. For example, each color resistance unit on the color film substrate includes a red color resistance block, a green color resistance block, and a blue color resistance block, the first color resistance block may include a red color resistance block, and the red color resistance block may allow red light to pass through; the second color block may include a green color block that may allow green light to pass and a blue color block that may allow blue light to pass.
Specifically, the cell thickness of the edge region of the display panel is greater than the cell thickness of the central region of the display panel, and as shown in fig. 4, the first gray mask may include a red gray mask 41, and the second gray mask may include a green gray mask 42 and a blue gray mask 43.
the red gray mask 41 may include: an unobstructed area 411 through which all light can pass, and a second obstructed area 412 through which some light can pass. The green gray mask 42 may include: a first blocking area 421 through which a part of light can pass, and a third blocking area 422 through which a part of light can pass. The blue gray mask plate 43 may include: a first blocking area 431 through which a part of light can pass, and a third blocking area 432 through which a part of light can pass.
The non-shielding region 411 corresponds to a region where the edge region P of the substrate base 111 forms the red color block R, the first shielding region 421 corresponds to a region where the edge region P of the substrate base 111 forms the green color block G, the first shielding region 431 corresponds to a region where the edge region P of the substrate base 111 forms the blue color block B, the second shielding region 412, the third shielding region 422, and the third shielding region 432 correspond to a central region of the substrate base, specifically, the second shielding region 412 corresponds to a region where the central region Q of the substrate base 111 forms the red color block R, the third shielding region 422 corresponds to a region where the central region Q of the substrate base 111 forms the green color block G, and the third shielding region 432 corresponds to a region where the central region Q of the substrate base 111 forms the blue color block B.
Among the non-shielded region 411, the first shielded region 421, the first shielded region 431, the second shielded region 412, the third shielded region 422 and the third shielded region 432, the light transmittance of the non-shielded region 411 is the highest, the light transmittances of the second shielded region 412, the third shielded region 422 and the third shielded region 432 may be equal to each other, and at the same time, the light transmittances may be smaller than those of the first shielded region 421 and the first shielded region 431, and the light transmittances of the first shielded region 421 and the first shielded region 431 may be equal to each other.
For example, as shown in fig. 5, the light shielding mode of the shielding region in the above-mentioned gray mask (the red gray mask 41, the green gray mask 42, or the blue gray mask 43) may be a halftone mask (HTM) mode or a single plate mask (SSM) mode.
In step 302, when a plurality of color resist units arranged in an array are formed on a substrate, a first gray mask may be used to form a first color resist block on the substrate by a patterning process, and a second gray mask may be used to form a second color resist block on the substrate by the patterning process, where the first color resist block and the second color resist block are both formed in an edge region of the substrate.
Specifically, as shown in fig. 6-1, a plurality of red color resist blocks R arranged in an array may be formed on the substrate 111 by a single patterning process using a red gray mask 41.
