Fig. 2 is a top view of a display panel according to an embodiment of the invention, fig. 3 is a schematic diagram of a pixel arrangement in the display panel according to the embodiment of the invention, please refer to fig. 2 and fig. 3, a display panel 100 according to an embodiment of the invention includes a plurality of pixel columns L arranged in a display area along a first direction D1 and a plurality of pixel rows H arranged along a second direction D2, sub-pixels P in the same pixel column L are arranged along the second direction D2, and the first direction D1 intersects the second direction D2;
the sub-pixel P comprises a first color resistor 10, the color of the first color resistor 10 in the same pixel column L is the same, and the color of the first color resistor 10 in two adjacent pixel columns L along the first direction D1 is different;
the display region includes a first edge B1 extending along the second direction D2, the pixel columns L include an edge pixel column BL adjacent to the first edge B1 and a center pixel column ZL on a side of the edge pixel column BL away from the first edge B1;
in the same edge pixel column BL, at least some of the sub-pixels further include a compensation structure 20 disposed around the first color resistor 10, and the color of the compensation structure 20 is different from the color of the first color resistor 10.
It should be noted that fig. 2 only illustrates a structure of the display panel provided by the present invention by taking a display panel with a rectangular structure as an example, in some other embodiments of the present invention, the display panel may also be embodied in a shape with an irregular edge, such as a rounded rectangle, and the present invention is not limited to this specifically. Fig. 3 only illustrates the pixel arrangement by taking a part of the sub-pixels in the display panel as an example, and does not represent the actual number of sub-pixels included in the display panel, nor represents the actual shape and size of the sub-pixels, and in some other embodiments of the present invention, the number, shape and size of the sub-pixels can be adjusted according to the actual situation.
With continued reference to fig. 2 and fig. 3, in the display panel provided in the embodiment of the present invention, a plurality of pixel columns L arranged along the first direction D1 are disposed in the display area, the colors of the first color resists 10 corresponding to the sub-pixels in the same pixel column L are the same, and the colors of the first color resists 10 corresponding to the sub-pixels in two adjacent pixel columns L along the first direction D1 are different. The pixel columns L include an edge pixel column BL adjacent to the first edge B1 and a center pixel column ZL on a side of the edge pixel column BL away from the first edge B1. Particularly, for the edge pixel column BL, the compensation structure 20 is disposed in at least a part of the sub-pixels in the edge pixel column BL, and the compensation structure 20 is disposed around the first color resistor 10 to compensate the color of the light emitted from the first color resistor 10 in the edge pixel column BL, so that the phenomenon of red edge or blue edge due to color mixing of non-corresponding pixels of the sub-pixels in the edge pixel column BL is improved, and therefore, the problem of poor display of the display panel in the corresponding region of the edge pixel column BL is improved, which is beneficial to improving the display effect of the display panel.
In the related art, when the pixel arrangement shown in fig. 1 is adopted, assuming that RGBRGB … … RGB is repeatedly arranged, when a white image is displayed on the display panel, referring to fig. 4, a red sub-pixel located at the leftmost edge region will emit a part of red light at the left side of the pixel without color mixing with the red sub-pixel, and thus will appear red at the left edge region; the blue sub-pixel at the rightmost edge region will emit a part of blue light at the pixel to which the blue sub-pixel is not mixed at the right side thereof, and thus the blue sub-pixel at the right edge region will exhibit a blue-emitting phenomenon, wherein fig. 4 is a light distribution diagram of the display panel in a white picture line in the related art.
In the display panel provided by the embodiment of the invention, at least part of sub-pixels in the edge pixel column BL are improved, the compensation structure 20 with a color different from that of the first color resistor 10 is arranged around the first color resistor 10, and the compensation structure 20 compensates the light emitted by the edge pixel column BL under the display of a white picture, so that the phenomenon that the position of the edge pixel column BL presents an abnormal color under the white picture is weakened. When the first color resistor 10 corresponding to the edge pixel column BL is a red color resistor, the red color phenomenon at the edge can be weakened or eliminated; when the first color resists 10 corresponding to the edge pixel columns BL are blue color resists, it is beneficial to weaken or eliminate the phenomenon of edge bluing. Therefore, the present invention introduces the compensation structure 20 into the edge pixel rows BL to improve the display effect of the display panel under the white frame.
It should be noted that fig. 3 only shows the scheme of disposing the compensation structure 20 in a part of the sub-pixels in the edge pixel column BL, in some other embodiments of the present invention, the compensation structure 20 may be disposed in each sub-pixel of the edge pixel column BL, for example, referring to fig. 5, and fig. 5 shows another schematic pixel arrangement diagram in the display panel provided in the embodiment of the present invention, so as to implement a compensation function for the light of each sub-pixel in the edge pixel column BL.
In an alternative embodiment of the present invention, please refer to fig. 3 and 5, in the sub-pixels provided with the compensation structure 20, the area of the first color resistor 10 is smaller than the area of the first color resistor 10 corresponding to the sub-pixels in the central pixel row ZL.
Specifically, in the display panel provided in the embodiment of the invention, when the compensation structure 20 is disposed in the sub-pixel corresponding to the edge pixel row BL, the area of the first color resist 10 in the sub-pixel provided with the compensation structure 20 is smaller, specifically smaller than the area of the first color resist 10 corresponding to the sub-pixel of the center pixel row ZL. When the area of the first color resistor 10 in the edge pixel column BL is reduced, the display brightness corresponding to the edge pixel column BL is reduced, and the brightness of the light with a specific color (for example, red or blue) appearing at the edge is weakened to a certain extent, and when the compensation structure 20 is disposed around the portion of the first color resistor 10, the compensation structure 20 can also mix the color of the light passing through the corresponding first color resistor 10, and further weaken the phenomenon that the area corresponding to the edge pixel column BL displays an abnormal color, thereby being beneficial to improving the display effect of the display panel.
In an alternative embodiment of the present invention, fig. 6 is an AA cross-sectional view of the display panel corresponding to fig. 5, and the compensation structure 20 is made of a transparent material.
The display panel provided by the embodiment of the invention can be embodied as a liquid crystal display panel, for example, the liquid crystal display panel includes an array substrate and a color film substrate which are oppositely arranged, wherein a black matrix BM is arranged on the color film substrate, the black matrix BM defines a plurality of pixel openings K, and the first color resist 10 is filled in the pixel openings K. Usually, a transparent material, such as OC glue 30, is further disposed on the side of the color filter far from the black matrix to planarize the color filter substrate. It should be noted that fig. 6 only shows a part of the film layer structure on the color filter substrate, and does not show the array substrate, and the film layer structure of the array substrate may refer to the prior art, which is not limited in the present invention. For the edge pixel column BL, the size of the pixel opening corresponding to the sub-pixel of the edge pixel column BL can be kept consistent with the size of the pixel opening corresponding to the sub-pixel of the middle pixel column L, and the size of the first color resist 10 of at least part of the sub-pixels in the edge pixel column BL is made smaller, which is equivalent to that the corresponding pixel opening is not filled with the part of the first color resist 10. When the OC glue 30 is manufactured, the OC glue 30 fills the region of the pixel opening not filled by the first color resist 10, and the OC glue 30 is reused as the compensation structure 20. The OC glue 30 is a transparent material, and when the OC glue 30 is reused as the compensation structure 20, a new film structure does not need to be introduced into the display panel, so that the color mixing compensation of the light of the sub-pixels in the edge pixel column BL can be realized, and the whole manufacturing process of the display panel can be simplified. When transparent materials such as OC glue and the like are adopted as a compensation structure, the brightness of sub-pixels in an edge pixel column is improved to a certain extent.
Fig. 7 is a schematic diagram illustrating another pixel arrangement in the display panel according to the embodiment of the invention, and fig. 8 is a cross-sectional view of a BB of the display panel corresponding to fig. 7, which shows that the area of the pixel opening corresponding to the sub-pixel in the edge pixel column BL is smaller than the area of the pixel opening corresponding to the sub-pixel in the center pixel column ZL.
In an alternative embodiment of the present invention, at least some of the sub-pixels in the edge pixel column BL include a first pixel aperture K1, the first pixel aperture K1 is disposed with the compensation structure 20 and the first color resist 10, and the area of the first pixel aperture K1 is S1; in the central pixel row ZL, the area of the pixel opening K0 corresponding to the sub-pixel is S2, where S1 < S2.
Specifically, in the display panel provided by the embodiment of the present invention, in the same sub-pixel provided with the compensation structure 20, the first color resistance 10 and the compensation structure 20 are located in the same pixel opening, and when the compensation structure 20 is made of a transparent material such as OC glue 30, since the transmittance of the first color resist 10 is about 20%, and the transmittance of the compensation structure 20 corresponding to the transparent material may reach or approach 100%, that is, the transmittance of the compensation structure 20 is 5 times of the transmittance of the first color resist 10, even when the area of the first color resist 10 is reduced compared to the area of the first color resist 10 in the sub-pixels of the central pixel row ZL, the brightness of the sub-pixels corresponding to the edge area is very bright, a large difference may occur in the brightness of the pixels corresponding to the central pixel row ZL, and although the display abnormality such as left red, right blue may be improved, a new problem may occur. Therefore, in the embodiment of the present invention, the area of the first pixel opening K1 corresponding to the sub-pixel having the compensation structure 20 in the edge pixel column BL is made smaller than the area of the pixel opening K0 corresponding to the sub-pixel in the center pixel column ZL, so as to reduce the luminance of the sub-pixel having the compensation structure 20 in the edge pixel column BL, thereby improving the problem of edge abnormal display such as left red, right blue, and the like, and simultaneously being beneficial to reducing the display luminance difference between the edge pixel column BL and the middle pixel column L, thereby being beneficial to improving the overall display effect of the display panel.
Fig. 9 is a schematic diagram of another pixel arrangement in the display panel according to the embodiment of the present invention, in which the pixel openings corresponding to some of the sub-pixels in the edge pixel column BL have smaller areas than those of the pixel openings corresponding to the sub-pixels in the central pixel column ZL, and the pixel openings corresponding to some of the sub-pixels have equal areas to those of the pixel openings corresponding to the sub-pixels in the central pixel column ZL.
In an alternative embodiment of the invention, referring to fig. 9, at least a portion of the sub-pixels in the edge pixel row BL include a second pixel opening K2, only the first color resist 10 is disposed in the second pixel opening K2, and the area of the second pixel opening K2 is the same as the area of the single pixel opening K0 in the central pixel row ZL.
Specifically, when the area of the first pixel opening K1 filled with the sub-pixels of the compensation structure 20 in the edge pixel column BL is made smaller, in order to avoid the phenomenon that the overall brightness of the edge pixel column BL is reduced due to the reduction of the area of the first pixel opening K1, the area of the pixel opening (i.e., the second pixel opening K2) corresponding to at least some of the sub-pixels in the edge pixel column BL is kept unchanged, and the area of the pixel opening K0 corresponding to the sub-pixels in the center pixel column ZL is the same, which is beneficial to neutralizing the overall brightness of the edge pixel column BL, reducing the display brightness difference between the edge pixel column BL and the center pixel column ZL, and improving the abnormal display phenomenon of the edge region such as left red, right blue and the like, and is beneficial to improving the overall display effect of the display panel.
In an alternative embodiment of the present invention, with continued reference to fig. 9, the first pixel apertures K1 and the second pixel apertures K2 are alternately arranged along the second direction D2 in the same edge pixel column BL.
When the pixel openings corresponding to the sub-pixels in the edge pixel column BL include the first pixel opening K1 with a smaller area and the second pixel opening K2 with an area equal to that of the pixel opening K0 of the sub-pixel of the center pixel column ZL, optionally, along the second direction D2, the first pixel opening K1 and the second pixel opening K2 are alternately arranged to avoid the phenomenon that the same edge pixel column BL is locally too bright or too dark, so that while the phenomenon of edge abnormality display such as left red, right and blue is improved, the uniformity of the display brightness of the edge pixel column BL is also improved.
It should be noted that fig. 9 only shows an embodiment in which one first pixel opening K1 and one second pixel opening K2 are alternately arranged in the edge pixel column BL, in some other embodiments of the present invention, a manner in which n first pixel openings K1 and n second pixel openings K2 are alternately arranged may also be adopted, where n > 1, for example, two first pixel openings K1 and two second pixel openings K2 are alternately arranged, and the uniformity of the display luminance of the edge pixel column BL can also be improved.
Fig. 10 is a schematic diagram of another pixel arrangement in a display panel according to an embodiment of the present invention, where the embodiment shows a scheme that at least three pixel columns L located in an edge region are all designed differently from a central pixel column ZL, it should be noted that fig. 10 only shows pixel arrangements of a left edge region and a central region adjacent to the left edge region in the display panel, and does not show a pixel arrangement of a right edge region, and a left edge may be referred to for the pixel arrangement of the right edge region, which is not specifically limited by the present invention.
Referring to fig. 10, in an alternative embodiment of the invention, the pixel columns form at least one edge pixel column group BLZ and a center pixel column group ZLZ, and the edge pixel column groups BLZ are located on two sides of the center pixel column group ZLZ along the first direction D1;
the edge pixel column group BLZ includes at least three pixel columns, and each sub-pixel in the same edge pixel column group BLZ includes a first color resistance 10 and a compensation structure 20.
With reference to fig. 10, in the display panel according to the embodiment of the invention, in addition to the differential design of only the edge pixel column BL, the differential design of the sub-pixels in the pixel columns in the edge pixel column group BLZ can be performed. When the size of the pixel opening of at least some of the sub-pixels in the edge pixel column BL is reduced to reduce the size of the corresponding first color resistance 10, when the sub-pixel at the left edge is mixed with the sub-pixel at the right edge, or when the sub-pixel at the right edge is mixed with the sub-pixel at the left edge, a phenomenon of poor color mixing effect due to different amounts of light rays with different colors of color mixing may occur.
Fig. 11 is a schematic diagram of another pixel arrangement in a display panel according to an embodiment of the present invention, where the embodiment shows a scheme that a same edge region of the display panel includes at least two edge pixel column groups. It should be noted that fig. 11 only shows the pixel arrangement of the left edge region and the central region adjacent to the left edge region in the display panel, and does not show the pixel arrangement of the right edge region, and the left edge may be referred to for the pixel arrangement of the right edge region, which is not specifically limited in the present invention.
In an alternative embodiment of the present invention, referring to fig. 11, the edge pixel column group includes a first edge pixel column group BLZ1 and a second edge pixel column group BLZ2, and the second edge pixel column group BLZ2 is located between the first edge pixel column group BLZ1 and the center pixel column group ZLZ along the first direction D1;
in at least some pixel rows, the pixel opening areas of the sub-pixels in the first edge pixel column group BLZ1 and the sub-pixels in the second edge pixel column group BLZ2 are the same and are smaller than the pixel opening area of the sub-pixels in the center pixel column ZL, and the area of the first color barrier 101 in the first edge pixel column group BLZ1 is larger than the area of the first color barrier 102 in the second edge pixel column group BLZ 2.
It should be noted that, in the embodiment of the present invention, the first edge pixel column group BLZ1 and the second edge pixel column group BLZ2 are located on the same side of the display panel, and are applicable to two edge regions of the display panel that are oppositely disposed along the first direction D1.
When the display panel includes the first edge pixel column group BLZ1 and the second edge pixel column group BLZ2 between the first edge pixel column group BLZ1 and the center pixel column group ZLZ, the pixel opening areas of the sub-pixels in the first edge pixel column group BLZ1 and the second edge pixel column group BLZ2 may be the same and smaller than the opening area of the sub-pixels in the center pixel column group ZLZ, at least some of the pixel rows. Therefore, the pixel openings in the first edge pixel column group BLZ1 and the second edge pixel column group BLZ2 can be made in a uniform specification and size, which is beneficial to simplifying the manufacturing process of the display panel. At this time, the area of the first color resistor 101 corresponding to the sub-pixel in the first edge pixel column group BLZ1 is set to be larger than the area of the first color resistor 102 in the second edge pixel column group BLZ2, so that the area of the compensation structure 201 in the first edge pixel column group BLZ1 is smaller than the area of the compensation structure 202 in the second edge pixel column group BLZ2, that is, in the direction from the edge region to the central region, the area of the pixel aperture corresponding to each edge pixel column group BLZ is kept unchanged, the area of the compensation structure 20 is increased, the area of the compensation structure 20 is positively correlated with the luminance of the sub-pixel, therefore, the luminance of the edge region is gradually increased, that is, the luminance is gradually increased from the edge region to the central region, the luminance change is slow from the edge pixel column BL to the central pixel column, and the difference between the pixel columns L adjacent to the edge of the display region is avoided, the display brightness of the edge area and the display brightness of the central area have obvious difference, so that the whole display effect of the display panel is improved.
It should be noted that, in the same edge pixel column group BLZ, the area of the first color resistor 10 and the area of the compensation structure 20 are the same in the three sub-pixels in the same pixel row, so as to avoid the abnormal color mixing problem.
Fig. 12 is a schematic diagram illustrating another pixel arrangement in a display panel according to an embodiment of the present invention, where the embodiment shows another scheme that a same edge region of the display panel includes at least two edge pixel column groups BLZ. It should be noted that fig. 12 only shows the pixel arrangement of the left edge region and the central region adjacent to the left edge region in the display panel, and does not show the pixel arrangement of the right edge region, and the left edge may be referred to for the pixel arrangement of the right edge region, which is not specifically limited in the present invention.
In an alternative embodiment of the present invention, referring to fig. 12, the edge pixel column group includes a first edge pixel column group BLZ1 and a second edge pixel column group BLZ2, and the second edge pixel column group BLZ2 is located between the first edge pixel column group BLZ1 and the center pixel column group ZLZ along the first direction D1;
in at least some pixel rows, the pixel opening area of the sub-pixels located in the first edge pixel column group BLZ1 is smaller than the opening area of the sub-pixels located in the second edge pixel column group BLZ 2; in the edge pixel column group BLZ, the ratio of the area of the compensation structure 20 in at least some of the sub-pixels to the area of the first color resist 10 is the same.
It should be noted that, in the embodiment of the present invention, the first edge pixel column group BLZ1 and the second edge pixel column group BLZ2 are located on the same side of the display panel, and are applicable to two edge regions of the display panel that are oppositely disposed along the first direction D1.
When the display panel includes the first edge pixel column group BLZ1 and the second edge pixel column group BLZ2 located between the first edge pixel column group BLZ1 and the center pixel column group ZLZ, along the direction in which the edge region points to the center region, the area of the pixel openings in different edge pixel column groups tends to increase, and at the same time, in the sub-pixels located in the same row in the sub-pixels corresponding to different edge pixel column groups BLZ, the ratio of the area of the compensation structure 20 to the area of the first color resistor 10 may be set to be the same, for example, the ratio of the area of the compensation structure 201 to the first color resistor 101 of the BLZ1 in the first edge pixel column group is equal to the ratio of the area of the compensation structure 202 to the first color resistor 102 in the second edge pixel column group BLZ2, and thus, the larger area of the pixel opening, the corresponding display luminance will be larger. Therefore, in the direction from the edge region to the central region, the display brightness of the edge region tends to become gradually larger, so that the brightness change is slow from the edge pixel column BL to the central pixel column, thereby avoiding the problem that the display brightness of the edge region is obviously different from the display brightness of the central region when only the pixel column L adjacent to the edge of the display region is subjected to differential design, and being also beneficial to improving the overall display effect of the display panel.
Fig. 13 is a schematic diagram illustrating another pixel arrangement in a display panel according to an embodiment of the present invention, where the embodiment shows another scheme that a same edge region of the display panel includes at least two edge pixel column groups BLZ. It should be noted that fig. 13 only shows the pixel arrangement of the left edge region and the central region adjacent to the left edge region in the display panel, and does not show the pixel arrangement of the right edge region, and the left edge may be referred to for the pixel arrangement of the right edge region, which is not specifically limited in the present invention.
In an alternative embodiment of the present invention, with continued reference to fig. 13, in the edge pixel column group BLZ adjacent to the center pixel column group ZLZ, the area of the pixel opening corresponding to at least a part of the sub-pixels is the same as the area of the pixel opening corresponding to the sub-pixels in the center pixel column group ZLZ, and only the first color resists 10 are disposed in the pixel openings corresponding to the part of the sub-pixels in the edge pixel column group BLZ.
Specifically, fig. 13 illustrates an example of a scheme in which the same side edge of the display panel includes three edge pixel column groups BLZ and each edge pixel column group BLZ includes three pixel columns L, and in some other embodiments of the present invention, the same side edge of the display panel may further include other numbers of edge pixel column groups BLZ, which is not limited in this disclosure. When at least two edge pixel column groups BLZ are disposed in the same side edge region of the display panel, the pixel aperture area of a part of sub-pixels in the edge pixel column group BLZ adjacent to the center pixel column group ZLZ may be made large, and set to be the same as the pixel aperture area of sub-pixels in the center pixel column group ZLZ, for example, in the edge pixel column group BLZ adjacent to the center pixel column group ZLZ along the second direction D2, two adjacent rows of sub-pixels may be respectively set to be the pixel aperture K2 having a larger area (the same as the pixel aperture K0 in the center pixel column group ZLZ) and the pixel aperture K1 having a smaller area, so as to further reduce the display luminance difference between the edge pixel column group BLZ and the center pixel column ZLZ, so that the display luminance in the edge region and the center region can be smoothly transited, and the display effect of the display panel as a whole can be further improved.
It should be noted that fig. 13 shows that pixel openings with different sizes are alternately arranged in the edge pixel column BL adjacent to the center pixel column ZL along the second direction D2, the present invention does not limit the position of the sub-pixels with larger pixel openings in the edge pixel column BL, and may adopt a mode that one row of pixel openings K2 with a larger area is alternately arranged with one row of pixel openings K1 with a smaller area, or adopt a mode that two or more rows of pixel openings K2 with a larger area are alternately arranged with two or more rows of pixel openings K2 with a smaller area, so as to reduce the luminance difference with the center pixel column group ZLZ, and at the same time, to facilitate improving the overall image brightness uniformity of the edge pixel column group BLZ.
It should be noted that, in the above embodiment, the same pixel column L group includes sub-pixels with different three colors, for example, the three colors may be red, green, and blue, respectively, the sub-pixels in the same edge pixel column may be embodied as red, green, or blue, and the pixel arrangement may be embodied as RGB, GRB, BGR, or the like. After the transparent compensation structure is introduced into the edge pixel column or the sub-pixels in the edge pixel column group, no matter what color the edge pixel column presents, the introduction of the compensation structure is beneficial to improving the phenomena of red, blue or green emitting at the edge area of the display panel, and the overall display effect of the display panel is improved.
The above embodiments show the solution that the compensation structure is made of transparent material, and in some other embodiments of the present invention, the compensation structure may also be made of colored material, and the following embodiments will be described in detail.
Fig. 14 is a schematic diagram of another pixel arrangement in a display panel according to an embodiment of the present invention, which illustrates a scheme of non-transparency of the color of the compensation structure 20.
In an alternative embodiment of the present invention, referring to fig. 14, the sub-pixels include a first color sub-pixel P1, a second color sub-pixel P2 and a third color sub-pixel P3, and the sub-pixels in the edge pixel column BL are at least one of the first color sub-pixel P1, the second color sub-pixel P2 and the third color sub-pixel P3; the color of the sub-pixels in the edge pixel column BL is the same as the color of the first color resist 10 provided in the sub-pixels.
When the color of the first color resist 10 in the edge pixel column BL is the first color, the color of the compensation structure 20 is the second color or the third color.
With continued reference to fig. 14, the compensation structure 20 disposed in the sub-pixel of the edge pixel column BL may be made of a material having a color different from that of the first color resist 10 in the corresponding sub-pixel, in addition to the transparent material. Optionally, the colors of the first color resistors 10 in the display panel include a first color, a second color and a third color, and when the color of the first color resistor 10 corresponding to each sub-pixel in the edge pixel column BL is the first color, the color corresponding to the compensation structure 20 may be the second color or the third color. After the light passes through the first color resistor 10 and the corresponding compensation structure 20, the light corresponding to the color of the first color resistor 10 and the light corresponding to the color of the compensation structure 20 are respectively emitted, the light with two different colors can be mixed, and white light is emitted under a white display picture, so that the phenomenon that the display panel is displayed in an abnormal manner such as red or blue in the corresponding area of the edge pixel is improved, and the whole display effect of the display panel is favorably improved.
Alternatively, the compensation structure 20 may be made of the same material as the color resistor, on one hand, no new material needs to be introduced into the display panel, and on the other hand, the compensation structure 20 may be made in the same process step while the color resistor of the second color or the third color is made, thereby being further beneficial to simplifying the manufacturing process of the display panel.
Of course, the above embodiment only takes the color of the first color resist 10 in the edge pixel column BL as the first color, and the color of the compensation structure 20 as the second color or the third color as an example for explanation, in some other embodiments of the present invention, the color of the first color resist 10 in the edge pixel column BL may also be the second color or the third color, and the color of the compensation structure 20 may also be another color different from the second color or the third color, which is not specifically limited in the present invention.
It should be noted that the first color, the second color and the third color can be embodied as red, green and blue to realize the color display function of the display panel.
In an alternative embodiment of the present invention, please refer to fig. 14 and fig. 15, in which fig. 15 is a CC cross-sectional view of the display panel corresponding to fig. 14, the display panel includes a plurality of pixel openings K, and the first color resists 10 and the compensation structures 20 are located in the pixel openings K;
the area of the single pixel opening K1 corresponding to the edge pixel column BL is the same as the area of the single pixel opening K0 corresponding to the center pixel column ZL.
Specifically, when a colored material is used as the compensation structure 20, the pixel aperture area K1 corresponding to the sub-pixel in the edge pixel row BL is the same as the pixel aperture area K0 corresponding to the sub-pixel in the center pixel row ZL, that is, the pixel aperture areas of the sub-pixels on the display panel are the same, and a differential design is not required, which is beneficial to simplifying the manufacturing process of the display panel.
In addition, the implementation reduces the area of the first color resistor 10 corresponding to at least part of the sub-pixels in the edge region without changing the area of the pixel opening, and fills the compensation structure 20 with a different color around the part of the first color resistor 10, when the light passes through the part of the sub-pixels, the areas corresponding to the first color resistor 10 and the compensation structure 20 emit light with different colors respectively, and the two light with different colors are mixed, so that the phenomenon that the display panel emits abnormal red or abnormal blue in the edge region can be improved.
In the liquid crystal display panel, different pixel electrodes are usually arranged in the area corresponding to each sub-pixel, a common electrode is also arranged in the display panel, the common electrode receives a constant voltage signal, and a driving voltage is provided for the pixel electrodes, so that a voltage difference is generated between the pixel electrodes and the common electrode, the liquid crystal can be driven to deflect, and light can pass through the area corresponding to the sub-pixel, thereby realizing the display function.
In an alternative embodiment of the present invention, fig. 16 is a schematic structural diagram of a pixel electrode in a sub-pixel provided with a compensation structure 20, in the sub-pixel P provided with the compensation structure 20, the sub-pixel P includes a first pixel electrode 41 and a second pixel electrode 42, the first pixel electrode 41 overlaps with the first color resist 10, and the second pixel electrode 42 overlaps with the compensation structure 20 along a direction perpendicular to the light exit surface of the display panel; the first pixel electrode 41 and the second pixel electrode 42 are connected to different pixel driving circuits, respectively. It should be noted that, in order to clearly show the corresponding relationship between the compensation structure 20 and the second pixel electrode 42, the compensation structure 20 is not filled in fig. 16, and in fact, the compensation structure 20 may be embodied as a color resist structure of another color different from the color of the first color resist 10.
Specifically, in the sub-pixel provided with the compensation structure 20, when the compensation structure 20 adopts a color resistor with a color different from that of the corresponding first color resistor 10, two pixel electrodes may be disposed in the region corresponding to the sub-pixel, wherein the first pixel electrode 41 corresponds to the first color resistor 10, and the liquid crystal in the region where the first color resistor 10 is located can be driven to deflect by the voltage formed between the first pixel electrode 41 and the common voltage; the second pixel electrode 42 corresponds to the compensation structure 20, and a voltage formed between the second pixel electrode 42 and the common electrode can drive the liquid crystal in the region where the compensation structure 20 is located to deflect. Alternatively, the first pixel electrode 41 and the second pixel electrode 42 may be connected to different pixel driving circuits, and the voltages on the first pixel electrode 41 and the second pixel electrode 42 are controlled by the different pixel driving circuits, respectively. Assuming that the color of the first color resistor 10 is a first color and the color of the compensation structure 20 corresponding thereto is a second color, when the display panel displays a pure color picture, for example, the color of the display picture is the first color, only the pixel driving circuit corresponding to the first pixel electrode 41 is controlled to apply the pixel voltage to the first pixel electrode 41, only the liquid crystal in the region corresponding to the first color resistor 10 is deflected, but not the second pixel electrode 42 corresponding to the compensation structure 20, and the liquid crystal in the region corresponding to the compensation structure 20 is not deflected, and at this time, the color displayed by the sub-pixel is only the first color without doping the second color, thereby being beneficial to improving the pure color picture display effect of the display panel. On the contrary, when the color of the display panel displaying the pure color picture is the second color, only the pixel driving circuit corresponding to the second pixel electrode 42 is controlled to apply the voltage to the second pixel electrode 42, but not to apply the voltage to the first pixel electrode 41, only the liquid crystal in the area corresponding to the compensation structure 20 is deflected, the liquid crystal in the area corresponding to the first color resistor 10 is not deflected, and at this time, the color displayed by the pixel is only the second color without doping the first color, which is also beneficial to improving the pure color picture display effect of the display vertical panel.
When the display panel displays a white picture, the pixel driving circuit connected with the first pixel electrode 41 can be respectively controlled to apply a voltage signal to the first pixel electrode 41, and the pixel driving circuit connected with the second pixel electrode 42 can be controlled to apply a voltage signal to the second pixel electrode 42, so that liquid crystals in the region corresponding to the first color resistor 10 and the region corresponding to the compensation structure 20 can both deflect, and after light passes through the first color resistor 10 and the compensation structure 20, light rays with different colors can be mixed to form white light.

It should be noted that fig. 17 only shows that one edge pixel column group BLZ is disposed on the same side of the display panel, and in some other embodiments of the present invention, two or more edge pixel column groups may also be disposed on the same side of the display panel, which is not limited in this respect.
Specifically, fig. 17 shows a scheme in which the compensation structures 20 are provided in the sub-pixels in each of the plurality of pixel columns in the edge pixel column group BLZ, and fig. 17 explains an example in which the same edge pixel column group BLZ includes three pixel columns L. The compensation structure 20 is arranged in each sub-pixel in the edge pixel column group BLZ, so that the problem that the brightness of the edge pixel column BL is obviously different from the brightness of other pixel columns L when the compensation structure 20 is arranged only in the edge pixel column BL is solved, and the overall brightness uniformity of the display panel is improved while the red or blue phenomenon in the edge region of the display panel is improved. Furthermore, in the edge pixel column group BLZ, the areas of the first color resistors 10 corresponding to the sub-pixels are set to be the same, and the areas of the set compensation color resistors are also the same, so that the color mixing effect of the light of different sub-pixels in the same pixel unit is improved, and the color cast phenomenon is avoided.
With continued reference to fig. 17, in an alternative embodiment of the present invention, the compensation structures 20 corresponding to two sub-pixels adjacent to each other along the first direction D1 in the same edge pixel column group BLZ have different colors.
Assuming that, among the three pixels L included in the edge pixel column group BLZ, the first color resist 10 located in the first pixel column (the pixel column BL in the edge-most region) is the first color, the first color resist 10 located in the second pixel column (the pixel column L located in the middle of the three pixel columns) is the second color, and the color of the first color resist 10 located in the third pixel column (the pixel column close to the central pixel column group ZLZ among the three pixel columns) is the third color, the compensation structure 20 in the first pixel column is the third color, the compensation structure 20 in the second pixel column is the first color, and the compensation structure 20 in the third pixel column is the second color, that is, the colors of the compensation structures 20 in the two adjacent pixel columns are different, this is favorable to improving the color mixing effect of the sub-pixels adjacent to each other in the first direction D1 in the edge pixel column group BLZ, and is more favorable to improving the red or blue phenomenon of the display panel in the edge area.
