For example, when the blue light emitting diode emits light to excite quantum dots to generate green light and red light, and then the blue light is mixed with the light to generate white light to realize normal display of the display panel, a part of the quantum dots can be sacrificed due to edge region cutting, as shown in fig. 1, a part of the quantum dots 10 in the edge region are incomplete, and the incomplete quantum dots 10 are excited by the blue light to emit less red light and less green light, so that more blue light can be emitted in the edge region after mixing, which causes the display picture in the edge region to emit more blue light, and in the actual viewing process, the phenomenon that the periphery of the display picture emits blue light can occur, which affects the display quality of the display panel.
Therefore, it is an urgent technical problem to be solved by those skilled in the art how to improve the display quality of the display panel by improving the phenomenon that the periphery of the display screen of the display panel is biased to a certain color of light.

Detailed Description
The following describes in detail a specific embodiment of a display panel and a display device according to an embodiment of the present invention with reference to the drawings.
An embodiment of the present invention provides a display panel, as shown in fig. 2, which may include: the display device comprises subpixels arranged in an array along a first direction and a second direction intersecting the first direction, wherein the subpixels correspond to at least three different colors, for example, subpixels comprising three colors of red R, green G and blue B, and the first subpixel corresponds to the first color; the display panel comprises a central area and a peripheral area surrounding the central area, and the peripheral area comprises at least one annular sub-area m gradually extending from the edge of the display panel to the center of the display panel; in each annular sub-region m, the aperture ratio of the first sub-pixel 101 is smaller than the aperture ratios of the sub-pixels corresponding to other colors.
In the display panel provided by the embodiment of the invention, in the peripheral area of the display panel, the aperture ratio of the first sub-pixel is set to be smaller than the aperture ratios of the sub-pixels corresponding to other colors, so that the aperture ratio of the sub-pixel corresponding to the first color in the peripheral area is reduced, and light emitted by the sub-pixel corresponding to the first color in the peripheral area is reduced, so that when the quantum dot backlight is excited by light of the first color, the phenomenon that the peripheral area of the display screen of the display panel is biased towards the light of the first color can be effectively improved. For example, the first sub-pixel correspondingly emits blue light, and the blue sub-pixel in the peripheral area is set to be smaller than the aperture opening ratio of the red and green sub-pixels, so that when the quantum dot backlight source is excited by the blue light emitting diode, the light emitted by the blue sub-pixel in the peripheral area is correspondingly reduced, and after the light emitted by the red sub-pixel and the light emitted by the green sub-pixel are mixed, the phenomenon that the peripheral area of a display picture is biased to blue light can be effectively improved, and the display quality of the display panel can be improved.
In practical implementation, as shown in fig. 2, in the display panel provided in the embodiment of the present invention, in each annular sub-region m, the length of the first sub-pixel 101 along the first direction and/or the second direction is smaller than the length of the sub-pixels corresponding to other colors along the first direction and/or the second direction. Specifically, in the display panel provided in the embodiment of the present invention, the aperture ratio of the first sub-pixel is set to be smaller than the aperture ratios of the sub-pixels corresponding to other colors, and specifically, the length of the first sub-pixel along the first direction and/or the second direction is set to be smaller than the length of the sub-pixels corresponding to other colors along the first direction and/or the second direction, so that the light emitting area of the first sub-pixel is smaller than the light emitting areas of the sub-pixels corresponding to other colors, and thus, light emitted by the first sub-pixel can be reduced during display, and a phenomenon that a peripheral area of a display screen deviates from light of the first color is effectively improved.
In practical implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 2, the first color may be blue, that is, the first sub-pixel 101 may be a blue sub-pixel. Specifically, the color corresponding to the first sub-pixel may be blue, and the aperture ratio of the blue sub-pixel in the peripheral area is set to be smaller than the aperture ratios of the other colors, so that the phenomenon that the peripheral area of the display screen is blue can be effectively improved. Of course, the first sub-pixel can also correspond to other colors, so that the phenomenon that the peripheral area of the display screen deviates light corresponding to the color is improved.
In a specific implementation, in the display panel provided in the embodiment of the invention, as shown in fig. 3, in each annular sub-area, the widths L of the black matrixes at two sides of the first sub-pixel (B sub-pixel) may be equal. Specifically, the widths of the black matrixes at both sides of the first sub-pixel may be set to be equal, and when the aperture ratio of the first sub-pixel is reduced, the width of the first sub-pixel in the first direction and/or the second direction (fig. 3 illustrates the width in the second direction) may be correspondingly reduced by the same width from left to right with reference to the central symmetry axis.
In a specific implementation, in the display panel provided in the embodiment of the present invention, along an extending direction from the center to the edge of the display panel, widths of the black matrices on both sides of the first sub-pixel in each annular sub-area gradually increase. Specifically, the display panel based on the quantum dot backlight has a gradual change in the bluing in the peripheral area, that is, the display screen is more inclined to a certain color closer to the edge. Taking a blue led-excited quantum dot backlight as an example, as shown in fig. 4, the ordinate is the position of the test point on the CIE1931xy chromaticity diagram, Wx and Wy respectively represent the abscissa and ordinate of the test point on the chromaticity diagram, and the smaller the two are, the shorter the wavelength of the color on the chromaticity diagram is, the closer the wavelength to blue is, the more blue phenomenon occurs. Therefore, as can be seen from fig. 4, in the area on the display panel within 5mm from the edge, the blue light emission phenomenon of the display screen is more obvious, and the blue light emission of the display screen is stronger closer to the edge line, so that the display panel provided by the embodiment of the present invention can gradually increase the width of the black matrix at the two sides of the first sub-pixel in each annular sub-area along the extending direction from the center of the display panel to the edge, as shown in fig. 3, the aperture ratio of the first sub-pixel, that is, the blue sub-pixel, is smaller closer to the edge (the arrow in fig. 3 points to the edge from the center of the display panel), so that the blue light emission of the blue sub-pixel in the peripheral area can be effectively reduced, and the blue light emission phenomenon in the peripheral area of. Taking the display panel including red, green and blue sub-pixels as an example, the aperture ratio of each sub-pixel located in each annular sub-region can satisfy the following formula:
(Tr*Ar):(Tg*Ag):(Tb*Ab)＝(Tr*Ar1):(Tg*Ag1):(Tb*Ab1)；
wherein, Tr, Tg and Tb are the aperture penetration rates of the red, green and blue sub-pixels respectively; ar, Ag and Ab are respectively the aperture opening ratios of red, green and blue sub-pixels in the central area of the display panel; ar1, Ag1, and Ab1 are aperture ratios of the red, green, and blue subpixels in each of the annular sub-regions.
In practical implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 5a, the widths d of the black matrixes between the sub-pixels located in the central region C are equal; the width L of the black matrix at both sides of the first sub-pixel in each annular sub-region m is greater than the width d of the black matrix at both sides of the first sub-pixel in the central region C. Specifically, in the display panel provided by the embodiment of the present invention, (for example, in fig. 5a, the first sub-pixel is a blue pixel), widths of the black matrixes at two sides of the first sub-pixel in each annular sub-area may be set to be greater than widths of the black matrixes at two sides of the first sub-pixel in the central area, so that a size of the first sub-pixel in each annular sub-area relative to the first sub-pixel in the central area is reduced, an aperture ratio of the first sub-pixel is reduced, a light emitting area of the first sub-pixel in the peripheral area is reduced, light emitted by the first sub-pixel is reduced, and a phenomenon that the peripheral area of a display screen of the display panel is biased toward light of the first color is effectively improved. In addition, while the aperture ratio of the first sub-pixel is reduced to increase the width of the black matrix at two sides of the first sub-pixel, the aperture ratio of the sub-pixels of other colors adjacent to the left and right of the first sub-pixel can be increased, for example, the display panel comprises sub-pixels of three colors of red, green and blue, the first sub-pixel is a blue sub-pixel, the aperture ratio of the blue sub-pixel is reduced in the peripheral area, the aperture ratio of the red and green sub-pixels at two sides of the blue sub-pixel can be increased, and the phenomenon that the peripheral area of the display screen of the display panel is biased towards blue light is effectively improved; of course, according to the practical production requirement, the aperture ratio of the red and green sub-pixels may be as large as that of the central area, or slightly reduced, as long as the aperture ratio of the blue sub-pixel in the peripheral area is smaller than that of the other sub-pixels, and the phenomenon that the display screen is shifted to blue in the peripheral area can be improved.
In practical implementation, in the display panel provided by the embodiment of the present invention, as shown in fig. 5b and 5C, the widths d of the black matrixes between the sub-pixels located in the central region C are equal; the width L of the black matrix at both sides of the first sub-pixel in each annular sub-region m is less than (as shown in fig. 5 b) or equal to (as shown in fig. 5C) the width d of the black matrix at both sides of the first sub-pixel in the central region C. Specifically, in the display panel provided by the embodiment of the present invention, the widths of the black matrixes at two sides of the first sub-pixel in each annular sub-area may be set to be less than or equal to the widths of the black matrixes at two sides of the first sub-pixel in the central area, and the aperture ratios of the sub-pixels of the colors other than the first sub-pixel in each annular sub-area are greater than the aperture ratio of the sub-pixel of the corresponding color in the central area. Therefore, the aperture ratio of the first sub-pixel in the peripheral area can be reduced, the light emitted by the first sub-pixel is reduced, and the phenomenon that the peripheral area of the display picture of the display panel is deviated to the light of the first color can be effectively improved when the display panel normally emits light by being mixed with other colors.
In a specific implementation, in the display panel provided in the embodiment of the present invention, the display panel includes sub-pixels of three colors, namely, red, green, and blue, as an example for description, and in practical applications, the display panel provided in the embodiment of the present invention may also include: red, green, blue and white or red, green, blue and yellow. That is, the display panel provided by the embodiment of the present invention may be applied to a display panel with three primary colors or four primary colors, and specifically, may be selected according to actual production needs, and is not limited herein.

An embodiment of the present invention provides a display panel and a display device, where the display panel includes: the color filter comprises sub-pixels arranged in an array along a first direction and a second direction intersecting the first direction, wherein the sub-pixels correspond to at least three different colors, and the first sub-pixel corresponds to a first color; the display panel comprises a central area and a peripheral area surrounding the central area, and the peripheral area comprises at least one annular sub-area gradually extending from the edge of the display panel to the center of the display panel; in each annular sub-area, the aperture ratio of the first sub-pixel is smaller than the aperture ratios of the sub-pixels corresponding to other colors. In this way, in the peripheral area of the display panel, the aperture ratio of the first sub-pixel is set to be smaller than the aperture ratios of the sub-pixels corresponding to other colors, so that the aperture ratio of the sub-pixel corresponding to the first color in the peripheral area is reduced, and the light emitted by the sub-pixel corresponding to the first color in the peripheral area is reduced, so that when the quantum dot backlight is excited by the light of the first color, the phenomenon that the peripheral area of the display screen of the display panel is biased towards the light of the first color can be effectively improved.
