For example, the first color resistance may also be referred to as a second color resistance, and similarly, the second color resistance may also be referred to as a first color resistance without departing from the scope of embodiments of the present invention.
An embodiment of the present invention provides a color film substrate, as shown in fig. 1, fig. 1 is a top view of the color film substrate provided in an embodiment of the present invention, the color film substrate includes a substrate 1, the substrate 1 includes a main display area 2 and a camera component setting area 3, where the main display area 2 is an area corresponding to a conventional display area of a color film substrate where a display panel performs picture display, and the camera component setting area is an area corresponding to a setting position of a camera component of the display panel in the color film substrate.
As shown in fig. 2, fig. 2 is a cross-sectional view taken along a direction A1-A2 in fig. 1, the color filter substrate further includes a filter layer 4 disposed on the substrate 1, and the filter layer 4 includes a light shielding portion 5, a first filter portion 6, and a second filter portion 7. Wherein, the shading part 5 can be a black matrix and is used for limiting a plurality of sub-pixel opening areas 8, and the sub-pixel opening areas 8 are light outgoing areas of the sub-pixels; the plurality of sub-pixel opening areas 8 include a first opening area 9 located in the main display area 2 and a second opening area 10 located in the image pickup module setting area 3; the first filter part 6 is located in the main display area 2, the first filter part 6 includes a first color resistor 11, at least a part of the first color resistor 11 is located in the first opening area 9, and the first color resistor includes, for example, a red color resistor, a green color resistor, and a blue color resistor; the second filter portion 7 is located in the image pickup device installation area 3, the second filter portion 7 includes a second color resist 12 and a light-transmitting portion 13, the light-transmitting portion 13 is located in the second opening area 10, and at least a portion of the second color resist 12 is located in the second opening area 10, and the second color resist illustratively includes a red color resist, a green color resist, and a blue color resist.
Also, for the first and second open areas 9 and 10 emitting the same color light, the volume of the second color resist 12 in the second open area 10 is smaller than the volume of the first color resist 11 in the first open area 9.
To camera shooting subassembly setting area 3, when display panel is in the display mode, the light that the sub-pixel sent sees through second color resistance 12 and jets out to realize normal demonstration, when display panel is in the mode of making a video recording, the sub-pixel of camera shooting subassembly setting area 3 is luminous not, external environment light sees through second color resistance 12 and incides to the camera shooting subassembly in, second color resistance 12 carries out the filtration of certain degree to external environment light, and then utilizes camera shooting subassembly to gather external environment light, realize the function of making a video recording.
In the color filter substrate provided in the embodiment of the present invention, the light-transmitting portion 13 is disposed in the second opening region 10 of the image pickup device installation region 3, and the light-transmitting portion 13 occupies a certain space in the second opening region 10, so that the volume of the second color resist 12 filled in the second opening region 10 can be reduced to a certain extent and is smaller than the volume of the first color resist 11 filled in the first opening region 9 of the main display region 2. Therefore, when the display panel is in the image pickup mode, the external environment light penetrates through the second color resistor 12 and enters the image pickup assembly, so that the filtering degree of the second color resistor 12 to the external environment light can be reduced, the quantity of the light entering the image pickup assembly is increased, the imaging effect is effectively optimized, and the image pickup quality is improved.
Moreover, by adopting the color film substrate provided by the embodiment of the invention, the light transmission performance of the camera component setting area 3 is improved, and meanwhile, the number of sub-pixels of the display panel arranged in the camera component setting area 3 does not need to be reduced, so that the normal color display of the camera component setting area 3 is ensured, the higher pixel density of the camera component setting area 3 is also ensured, and the camera component setting area 3 still has good display performance.
Alternatively, referring to fig. 2 again, in the second opening region 10, the light-transmitting portion 13 and the second color resist 12 are stacked in a direction perpendicular to the plane of the substrate 1, and the second color resist 12 is located on a side of the light-transmitting portion 13 opposite to the substrate 1; further, for the first opening area 9 and the second opening area 10 which emit light of the same color, the thickness of the second color resist 12 is smaller than that of the first color resist 11 in the direction perpendicular to the plane of the base substrate 1.
When the transparent portion 13 and the second color resist 12 are arranged as described above, when a color filter substrate is manufactured, the transparent portion 13 having a certain thickness is formed in the second opening region 10, and then a photoresist material is applied to form the first color resist 11 and the second color resist 12. Because the photoresist material has certain fluidity, after coating the photoresist material, the thickness of the photoresist material filled in the second opening area 10 is smaller than that of the photoresist material filled in the first opening area 9, so that the thickness of the formed second color resistor 12 is smaller, when the display panel is in a camera shooting mode, the filtering degree of the second color resistor 12 to the external environment light is effectively reduced, and the light transmittance of the camera shooting component setting area 3 is optimized.
Further, as shown in fig. 3, fig. 3 is a schematic structural diagram of the light-transmitting portion provided by the embodiment of the present invention, in a direction perpendicular to the plane of the substrate 1, the thickness of the light-shielding portion 5 is T1, the thickness of the light-transmitting portion 13 is T2, and T1 and T2 satisfy: t2 is more than or equal to 1.3 × T1. Setting the minimum value of T2 to 1.3 × T1 allows the light-transmitting portion 13 to be completely filled in the groove defined by the light-shielding portion 5, so that when the second color resist 12 is formed by applying a photoresist material subsequently, the second color resist 12 can have a smaller thickness, thereby improving the light-transmitting performance of the image pickup device installation area 3 to a greater extent.
Further, referring to fig. 3 again, in the direction perpendicular to the plane of the substrate 1, the thickness of the light-transmitting portion 13 is T2, the thickness of the first color resist 11 is T3, and T2 < T3. When the light-transmitting portion 13 and the second color resist 12 are stacked, if the thickness of the light-transmitting portion 13 is larger than the thickness required for the first color resist 11, after a resist material having a certain thickness is coated on the light-transmitting portion 13, the resist material on the light-transmitting portion 13 flows to other regions, and it becomes difficult to form the second color resist 12 on the light-transmitting portion 13. Therefore, by making the thickness of the light-transmitting portion 13 smaller than the thickness required for the first color resist 11, it is possible to ensure that the photoresist material remains on the light-transmitting portion 13 in the process of forming the first color resist 11 and the second color resist 12, thereby improving the reliability of forming the second color resist 12.
In addition, in the embodiment of the present invention, after the light-transmitting portion 13 is additionally provided to reduce the thickness of the second color resistor 12 in the second opening area 10, when the display panel is in the display mode, after the light emitted by the sub-pixel passes through the second color resistor 12, the filtering degree of the light by the second color resistor 12 is correspondingly reduced, so that the color gamut of the picture displayed in the image pickup device installation area is reduced, and the brightness is increased.
When the first color resistor 11 and the second color resistor 12 in the color filter substrate respectively include a red color resistor, a green color resistor, a blue color resistor, and a white color resistor, the inventor compared the color gamut and brightness of the optical component setting area and the main display area 2 under the condition that the thickness T3 of the first color resistor 11 is 2.4 μm, the thickness T1 of the light shielding portion 5 is 1.1 μm, the thickness T2=1.3 × T1 of the light transmitting portion 13, and the thickness of the second color resistor 12 is about 1.0 μm:
referring to table 1, a in the table indicates that the main display area 2,B indicates that the camera module setting area 3,x and Y respectively indicate the abscissa and the ordinate in the CIE1931 chromaticity value test chart, and Y indicates luminance, it can be seen from table 1 that, after the thickness of the second color resistor 12 is adjusted as described above, the color gamut corresponding to the camera module setting area 3 is about 50% of the color gamut of the main display area 2, and the luminance corresponding to the camera module setting area 3 is 1.5 times the luminance of the main display area 2. Since the color gamut is within the visually acceptable color display range over 30% of the color gamut of the main display area 2, the thinning of the second color resist 12 does not significantly affect the display performance of the camera module installation area 3.
TABLE 1
Alternatively, as shown in fig. 4, fig. 4 is another cross-sectional view taken along a direction A1-A2 of fig. 1, the second opening area 10 is divided into a first area 14 and a second area 15, the light-transmitting portion 13 is located in the first area 14, and at least a portion of the second color resistor 12 is located in the second area 15. In practical applications, one second opening area 10 may include only one first area 14 and one second area 15 as shown in fig. 4, or may include a plurality of first areas 14 and a plurality of second areas 15, and the number of the first areas 14 and the number of the second areas 15 included in different second opening areas 10 may be the same or different.
When the light-transmitting portion 13 and the second color resist 12 are arranged as described above, in the process of manufacturing a color filter substrate, the light-transmitting portion 13 may be formed in the second opening region 10, and then the second color resist 12 is formed, or the light-transmitting portion 13 may be formed in the second opening region 10, and then the second color resist 12 is formed in the second opening region 10. This kind of mode of setting has reduced the area occupied of second colour resistance 12 in second open area 10 to when display panel was in the mode of making a video recording, effectively reduced the second colour resistance 12 to the filtration degree of external environment light, improved the light permeability of the subassembly setting area 3 of making a video recording.
Further, the area of the second opening region 10 is S1, the area of the first region 14 is S2, and S2 is 0.22 × S1 or more. Exemplarily, as shown in fig. 5, fig. 5 is a schematic area diagram of a light-transmitting portion provided by an embodiment of the present invention, a width of the second opening region 10 perpendicular to an extending direction thereof is L1, and a width of the first region 14 perpendicular to the extending direction thereof is L2, so that S1 and S2 satisfy that L2 ≧ 0.22 × L1, such that S1 and S2 satisfy that S2 ≧ 0.22 × S1.
The minimum value of S2 is set to 0.22 × S1, and the light transmission portion 13 occupies a larger area in the second opening region 10, so that the occupied area of the second color resist 12 in the second opening region 10 is effectively reduced, and the light transmission performance of the image pickup device installation region 3 is improved to a greater extent. And when S2 is more than or equal to 0.22 multiplied by S1, compared with the main display area 2, the brightness of the camera shooting component setting area 3 can be improved by more than 50 percent, thereby effectively improving the display brightness of the camera shooting component setting area 3.
Alternatively, as shown in fig. 6, fig. 6 is another schematic structural diagram of the light-transmitting portion 13 provided in the embodiment of the present invention, where the second color resistor 12 includes a second red color resistor 16, a second green color resistor 17, and a second blue color resistor 18, and correspondingly, the second opening area 10 includes a second red light opening area 19 provided with the second red color resistor 16, a second green light opening area 20 provided with the second green color resistor 17, and a second blue light opening area 21 provided with the second blue color resistor 18.
Referring to FIG. 6 again, the areas of the first regions 14 of at least two of the second red, green and blue open areas 19, 20 and 21 are different according to the chromaticity and white point requirements of the display panel when displaying a picture, for example, the area of the first region 14 in the second blue open area 21 is smaller than the area of the first region 14 in the second red and green open areas 19 and 20. And/or, as shown in FIG. 7, FIG. 7 is another schematic diagram of the structure of the light-transmitting portion provided by the embodiment of the present invention, according to the brightness center and visual effect of the picture displayed by the display panel, the positions of the first areas 14 of at least two second opening areas 10 of the second red light opening area 19, the second green light opening area 20 and the second blue light opening area 21 are different, for example, the second opening area 10 includes a first side and a second side which are oppositely arranged, the first area 14 of the second green light opening area 20 is located at the first side of the second green light opening area 20, and the first area 13 of the second red light opening area 19 is located at the second side of the second red light opening area 19.
Optionally, referring again to fig. 7, the second color resistor 12 includes a second red color resistor 16, a second green color resistor 17 and a second blue color resistor 18, and correspondingly, the second opening area 10 includes a second red light opening area 19 having the second red color resistor 16, a second green light opening area 20 having the second green color resistor 17 and a second blue light opening area 21 having the second blue color resistor 18. Further, the image pickup device installation area 3 includes a white light opening area 23 provided with a white color resist 22, and in the second green light opening area 20, the second green color resist 17 is located on the side of the light transmitting portion 13 adjacent to the white light opening area 23.
When the camera component setting area 3 includes the white light opening area 23 for emitting white light, the light emitting luminance of both the white light opening area 23 and the second green light opening area 20 is high, and if the light transmitting portion 13 in the second green light opening area 20 is close to the white light opening area 23, the white light emitted through the light transmitting portion 13 of the second green light opening area 20 and the white light emitted from the white light opening area 23 are easily converged together to form a bright point, which is recognized by human eyes. For this reason, the second green color filter 17 is disposed on the side of the light-transmitting portion 13 close to the white light opening area 23, so that the light-transmitting portion 13 of the second green light opening area 20 can be separated from the white light opening area 23, and the light rays emitted from the two can be prevented from converging to form a bright point.
In addition, in the embodiment of the present invention, since the light-transmitting portion 13 has a mutually independent film structure provided corresponding to each second opening region 10, in the process of forming the light-transmitting portion 13, after a light-transmitting material for forming the light-transmitting portion 13 is applied to the base substrate 1, it is necessary to expose and develop the light-transmitting material, and then etch the light-transmitting material into a desired pattern. For this purpose, the light-transmitting portion 13 may be formed of an epoxy resin or the like doped with a photoresist.
It should be noted that, when the image pickup device installation area 3 includes the white light opening area 23, the white resistors 22 may also be independent film structures respectively disposed corresponding to the white light opening areas 23, in which case, the white resistors 22 may be formed of the same material as the light transmission portion 13, for example, the white resistors 22 and the light transmission portion 13 may be formed of epoxy resin doped with a photoresist.
Alternatively, as shown in fig. 8, fig. 8 is another structural schematic diagram of the white color resistor provided in the embodiment of the present invention, the white color resistor 22 may also be a whole film structure covering the main display area 2 and the image pickup device setting area 3, and at this time, the white color resistor 22 does not need to be exposed and developed in the manufacturing process, so the white color resistor 22 may be formed by using a light-transmitting material without doped photoresist. Since light of any color can be emitted through the white color resist 22, even if the white color resist 22 is entirely covered, normal display in the main display area 2 and the image pickup device installation area 3 is not affected.
Based on the same inventive concept, an embodiment of the present invention further provides a display panel, as shown in fig. 9, where fig. 9 is a schematic structural diagram of the display panel provided in the embodiment of the present invention, and the display panel includes: the color film substrate 100; an array substrate 200 disposed opposite to the color filter substrate 100; the liquid crystal 300 is filled between the color filter substrate and the array substrate, wherein the specific structure of the color filter substrate 100 has been described in detail in the above embodiments, and is not described herein again. In addition, referring to fig. 9 again, the display panel may further include a light guide plate 400 and a camera assembly 500 located on a side of the array substrate 200 opposite to the color filter substrate 100, wherein a position of the camera assembly 500 corresponds to a position of the camera assembly setting area 3 in the color filter substrate 100.
In the display panel provided in the embodiment of the present invention, the light-transmitting portion 13 is additionally disposed in the second filtering portion 7 of the color filter substrate 100, so as to reduce the volume of the second color resistor 12 filled in the second opening region 10, and when the display panel is in the image capturing mode, the external environment light is incident to the image capturing component through the second color resistor 12, so that the filtering degree of the second color resistor 12 on the external environment light can be reduced, and further, the quantity of light incident to the image capturing component is increased, the imaging effect is effectively optimized, and the image capturing quality is improved.
