Description

Display panel and display device
Technical Field
The present invention relates to display technologies, and in particular, to a display panel and a display device.
Background
With the development of display technology, users have higher and higher requirements for the quality of the picture displayed by the display device.
Conventional display screens typically use Red Green Blue (RGB) pixels to form the minimal repeating unit and full colors by color matching. However, the luminance of the display panel using the RGB pixels is relatively low, and in order to increase the luminance of the display panel, in the prior art, a white sub-pixel is added to the RGB pixels, and the luminance of the display panel is increased by the white sub-pixel. Fig. 1 is a schematic diagram of a pixel arrangement of an RGBW display panel in the prior art, and referring to fig. 1, in a conventional red, green, blue, and white (RGBW) display screen, a blue sub-pixel in a part of RGB repeating units is replaced by a white sub-pixel, but since a yellow sub-pixel is formed by a red sub-pixel and a green sub-pixel, a yellow color of the repeating unit in the display panel is likely to be yellow when displaying white. The prior art typically synthesizes a normal white color by reducing the brightness of the red and green sub-pixels to match the blue sub-pixels; or the normal white color can be ensured by reducing the size of the white sub-pixel and increasing the size of the blue sub-pixel. Obviously, the transmittance of the RGBW display panel is also reduced to some extent by the above method.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As described in the background section, in the RGBW display panel shown in fig. 1, although the display luminance of the display panel is improved by replacing the blue sub-pixel with the white sub-pixel in the partial repeating unit, since the partial repeating unit can only light the red sub-pixel and the green sub-pixel when displaying the white sub-pixel, at this time, the light emitted by the red sub-pixel and the green sub-pixel will be mixed into yellow light, so that the partial repeating unit in the display panel has a problem that the color is yellowish when displaying white, and thus the display image has a deviation and the display quality is poor.
In view of the above problem, an embodiment of the present invention provides a display panel, and fig. 2 is a schematic structural diagram of a display panel provided in an embodiment of the present invention, and referring to fig. 2, the display panel includes a pixel array 10, where the pixel array 10 includes a plurality of first repeating units 11 arranged in an array; the first repeating unit 11 includes a first color sub-pixel 111, a second color sub-pixel 112, and a white sub-pixel 110, and light emitted from the first color sub-pixel 111 and the second color sub-pixel 112 may be mixed to form white light.
The pixel array 10 of the display panel is generally composed of a plurality of repeating units arranged in an array, and when the display panel displays a picture, the repeating units arranged in an array respectively display different colors, and then the different colors are combined to form the picture, and each repeating unit is a pixel structure with a definite position and color value in the display panel. The display panel provided by the embodiment of the invention is provided with a plurality of first repeating units 11 arranged in an array, wherein the first color sub-pixels 111 and the second color sub-pixels 112 are single-color sub-pixels, and when the display panel displays a picture, the light emitting colors of the first repeating units 11 can be adjusted by adjusting the brightness of the single-color light emitted by the first color sub-pixels 111 and the second color sub-pixels 112. The white sub-pixel 110 can be turned on to provide white light when displaying a picture, so as to increase the brightness of the display picture. In the first repeating unit 11, the first color sub-pixel 111, the second color sub-pixel 112 and the white sub-pixel 110 are arranged in various combinations, and for example, the first color sub-pixel 111 and the second color sub-pixel 112 may be arranged in close proximity to ensure that the first color sub-pixel 111 and the second color sub-pixel 112 cooperate to display white light. When the first color sub-pixel 111 is a blue sub-pixel and the second color sub-pixel 112 is a yellow sub-pixel, the color arrangement order of the color sub-pixels in the first repeating unit 11 may be white, yellow and blue. Preferably, there are and only the first color sub-pixel 111, the second color sub-pixel 112 and the white sub-pixel in the first repeating unit 11.
In the display panel provided in the embodiment of the present invention, the plurality of first repeating units arranged in an array are arranged in the pixel array, the first color sub-pixel, the second color sub-pixel and the white sub-pixel are arranged in the first repeating unit, and lights emitted by the first color sub-pixel and the second color sub-pixel can be mixed to form white light, so that on one hand, the white sub-pixel in the first repeating unit improves the light emitting brightness of the display panel; on the other hand, the light emitted by the first color sub-pixel and the light emitted by the second color sub-pixel can be mixed to form white light, so that the problem that color deviation can occur when white is displayed in the first repeating unit is avoided, and the display quality of the display panel is ensured.
With continued reference to fig. 2, optionally, the display panel further includes a plurality of second repeating units 12 in addition to the first repeating units 11 arranged in an array, and the plurality of first repeating units 11 and the plurality of second repeating units 12 are arranged in an array; the second repeating unit 12 includes a third color sub-pixel 113, a fourth color sub-pixel 114, and a first color sub-pixel 111. The light emitted from the third color sub-pixel 113, the fourth color sub-pixel 114, and the first color sub-pixel 111 may be mixed to form white light.
Since the third color sub-pixel 113, the fourth color sub-pixel 114 and the first color sub-pixel 111 in the second repeating unit 12 can be mixed to form white light, the third color sub-pixel 113, the fourth color sub-pixel 114 and the first color sub-pixel 111 can also control the respective light emitting brightness to enable the second repeating unit to realize full color light, thereby ensuring the display of full color pictures of the display panel. There are various arrangement combinations of the third color sub-pixel 113, the fourth color sub-pixel 114 and the first color sub-pixel 111 in the second repeating unit 12, for example, the second repeating unit 12 may be designed according to the arrangement order of the first color sub-pixel 111, the third color sub-pixel 113 and the fourth color sub-pixel 114, when the first color sub-pixel 111 is a blue sub-pixel, the third color sub-pixel 113 and the fourth color sub-pixel 114 are respectively a red sub-pixel and a green sub-pixel, and thus the color arrangement order of the color sub-pixels in the second repeating unit 12 is blue-red-green. Of course, since the plurality of first repeating units 11 and the plurality of second repeating units 12 are arranged in an array, the arrangement of the color sub-pixels of the second repeating units 12 can be properly designed according to the arrangement of the color sub-pixels of the first repeating units 11, and will not be discussed here. Preferably, there are and only the third color sub-pixel 113, the fourth color sub-pixel 114 and the first color sub-pixel 111 in the second repeating unit 12.
The pixel array 10 shown in fig. 2 may be a liquid crystal pixel array, or an organic light emitting pixel array, fig. 3 is a cross-sectional structural view of a display panel according to an embodiment of the present invention, and referring to fig. 3, wherein, when the pixel array 10 is a liquid crystal pixel array, the liquid crystal display panel may include a backlight module 20, an array substrate 21, a liquid crystal layer 23, a color filter (color resist) 22 and a color filter substrate 24, wherein the color sub-pixels in the first repeating unit 11 and the second repeating unit 12 are each distinguished by different colors through a filter, the sub-pixel structures are distinguished by liquid crystal cells in the liquid crystal layer 23, and for the control of each color sub-pixel, the liquid crystal in the liquid crystal box can be driven, and the light transmittance of the liquid crystal in the liquid crystal box to the backlight is changed, so that the color sub-pixels are turned on and off. In the liquid crystal pixel array, the lighting of the color sub-pixels is essentially the process of adjusting the transmittance of the liquid crystal in the liquid crystal cell to the maximum. Fig. 4 is a cross-sectional structural view of another display panel according to an embodiment of the present invention, referring to fig. 4, in a case that the pixel array 10 is an organic light emitting pixel array, the organic light emitting pixel array is composed of a plurality of organic light emitting units 30 arranged in an array, the organic light emitting units 30 may be disposed on a substrate 31 and covered by an encapsulation structure 32, each organic light emitting unit 30 can independently emit light and can be independently controlled, each organic light emitting unit 30 is a color sub-pixel, and a light emitting material of a light emitting layer in the organic light emitting unit 30 determines a color of the color sub-pixel.
With continued reference to fig. 3 and 4, no matter what display panel is, for the first color sub-pixel, the second color sub-pixel, and the white sub-pixel in the first repeating unit, and the first color sub-pixel, the third color sub-pixel, and the fourth color sub-pixel in the second repeating unit, the pixel driving circuit 40 may be respectively and correspondingly disposed, and each sub-pixel may be driven by the pixel driving circuit 40 to independently emit light, so as to realize independent control and driving of each color sub-pixel, thereby realizing display of different pictures.
In the display panel shown in fig. 2, the first repeating units 11 and the second repeating units 12 may be alternately arranged in the row direction, but it is of course possible to arrange the first repeating units 11 and the second repeating units 12 alternately in the column direction, and it is also possible to arrange the first repeating units 11 and the second repeating units 12 alternately in the row and column directions at the same time. Fig. 5 is a schematic structural diagram of another display panel according to an embodiment of the present invention, fig. 6 is a schematic structural diagram of another display panel according to an embodiment of the present invention, and referring to fig. 2, fig. 5 and fig. 6, where in the pixel array of the display panel shown in fig. 2, the first repeating units 11 and the second repeating units 12 are alternately arranged along the row direction, in the pixel array of the display panel shown in fig. 5, the first repeating units 11 and the second repeating units 12 are alternately arranged along the column direction, and in the pixel array of the display panel shown in fig. 6, the first repeating units 11 and the second repeating units 12 are alternately arranged not only along the row direction but also along the column direction. By arranging the first repeating units 11 and the second repeating units 12 alternately, the first repeating units 11 having the white sub-pixels can be ensured to be uniformly distributed in the pixel array 10, so that the brightness of the display panel is increased more uniformly. In the arrangement of the first repeating unit 11 and the second repeating unit 12 shown in FIGS. 2, 5 and 6, the smallest repeatable unit of the display panel of which it is composed is also very different, and for the display panel shown in fig. 2, the smallest repeatable unit 13 of which is composed of one second repeatable unit 12 and one first repeatable unit 11 adjacent in the row direction, for the display panel shown in fig. 5, the smallest repeatable unit 13 thereof is composed of one second repeatable unit 12 and one first repeatable unit 11 adjacent in the column direction, and for the display panel shown in fig. 6, the minimum repeatable unit 13 is composed of four repeated units which are overlapped in a crossing way in two adjacent rows and two adjacent columns, comprising two first recurring units 11 located diagonally and two second recurring units 12 located diagonally.
Since the same first color sub-pixels 111 are present in the first repeating unit 11 and the second repeating unit 12, in order to simplify the manufacturing process of the display panel, referring to fig. 2 and 6, two first color sub-pixels 111 in adjacent first repeating units 11 and second repeating units 12 may be disposed to be adjacent, wherein two first color sub-pixels 111 in the first repeating unit 11 and the second repeating unit 12 adjacent in the column direction shown in fig. 2 are adjacent, and two first color sub-pixels 111 in the first repeating unit 11 and the second repeating unit 12 adjacent in the row direction shown in fig. 6 are adjacent. Fig. 7 to 9 are schematic structural diagrams of three display panels provided in an embodiment of the present invention, and referring to fig. 7 to 9, regarding the arrangement manner of each sub-pixel in the first repeating unit 11 and the second repeating unit 12 in the pixel array 10, the sub-pixels may also be disposed in two first repeating units 11 and second repeating units 12 adjacent to each other in the column direction, and the sub-pixel 111 of the first color in the first repeating unit 11 and the sub-pixel 111 of the first color in the second repeating unit 12 are disposed adjacent to each other in the column direction; and/or in two first repeating units 11 and second repeating units 12 adjacent in the row direction, the first color sub-pixel 111 in the first repeating unit 11 and the first color sub-pixel 111 in the second repeating unit 12 are adjacently arranged in the row direction. Wherein, in the pixel array shown in fig. 8 and 9, the two first-color sub-pixels 111 in the first repeating unit 11 and the second repeating unit 12 are adjacent in the column direction; in the pixel array shown in fig. 6, two first-color sub-pixels 111 in the first repeating unit 11 and the second repeating unit 12 are adjacent in the row direction; in the pixel array shown in fig. 7, two first-color sub-pixels 111 in the first repeating unit 11 and the second repeating unit 12 are adjacent in both the row direction and the column direction.
It should be noted that the sub-pixels in the first repeating unit 11 and the second repeating unit 12 are not limited to the arrangement shown in fig. 2 and fig. 5 to 7, and for example, the white sub-pixel in the first repeating unit 11 may be disposed between the first color sub-pixel and the second color sub-pixel, which is not described herein.
Specifically, regarding the colors of the first color sub-pixel, the second color sub-pixel, the third color sub-pixel, and the fourth color sub-pixel in the first repeating unit and the second repeating unit, it is generally considered that three primary colors of white light are red, green, and blue, and thus, the third color sub-pixel, the fourth color sub-pixel, and the first color sub-pixel in the second repeating unit may be one of a red sub-pixel, a green sub-pixel, and a blue sub-pixel and may be different from each other. For example, the first color sub-pixel may be a blue color sub-pixel, and the third color sub-pixel and the fourth color sub-pixel are a red color sub-pixel and a green color sub-pixel, respectively, and the second color sub-pixel in the first repeating unit 11 must be a yellow color sub-pixel to ensure that the light emitted from the first color sub-pixel and the light emitted from the second color sub-pixel in the first repeating unit can be mixed to form white light.
It is obvious that the first color sub-pixel determines the color of the second color sub-pixel, and for example, when the first color sub-pixel is a red sub-pixel, the second color sub-pixel is a cyan sub-pixel, and the third color sub-pixel and the fourth color sub-pixel include a blue sub-pixel and a green sub-pixel. When the first color sub-pixel is a green sub-pixel, the second color sub-pixel is a magenta sub-pixel, and the third color sub-pixel and the fourth color sub-pixel comprise a red sub-pixel and a blue sub-pixel.
Referring to fig. 7 to 9, it should be noted that, although the first color sub-pixel and the second color sub-pixel are disposed in the first repeating unit to form white light by light emission mixture, the first repeating unit cannot display colors of the third color sub-pixel and the fourth color sub-pixel, for example, when the first color sub-pixel, the second color sub-pixel, the third color sub-pixel and the fourth color sub-pixel are respectively a blue sub-pixel, a yellow sub-pixel, a red sub-pixel and a green sub-pixel, when the display panel needs to display a green or red picture, the first repeating unit can only light the white sub-pixel when the first repeating unit cannot display the green or red, and when the display panel needs to display a blue picture, the first repeating unit can light the blue sub-pixel and the white sub-pixel when the display panel obviously displays a green or red picture, when compared with other, for example, blue, pictures, the color brightness is relatively weak, thereby affecting the display effect of the display panel. In view of the above, an embodiment of the present invention provides a display panel, and fig. 10 is a schematic structural diagram of another display panel provided in an embodiment of the present invention, and referring to fig. 10, optionally, areas of the third color sub-pixel 113 and the fourth color sub-pixel 114 are both larger than an area of the first color sub-pixel 111. At this time, when the display panel displays the color screens of the third color sub-pixel and the fourth color sub-pixel, since the third color sub-pixel and the fourth color sub-pixel in the second repeating unit are both larger than the area of the first color sub-pixel, the color brightness when the color screens of the third color sub-pixel and the fourth color sub-pixel are displayed can be relatively improved to a certain extent.
Of course, in order to ensure the color brightness of the display panel when displaying the color image of the third color sub-pixel and the fourth color sub-pixel, the display brightness of the third color sub-pixel and the fourth color sub-pixel may be increased, specifically, for the liquid crystal display panel, the transmittance of the filter of the third color sub-pixel and the fourth color sub-pixel with respect to the filter of the first color sub-pixel may be increased, and for the organic light emitting display panel, the driving current of the third color sub-pixel and the fourth color sub-pixel may be increased, so as to increase the light emitting brightness. At this time, the areas of the sub-pixels in the first repeating unit and the sub-pixels in the second repeating unit of the display panel may be set to be equal.
In order to further improve the display brightness of the display panel, the white sub-pixel may have the largest area among the first color sub-pixel, the second color sub-pixel, the third color sub-pixel, the fourth color sub-pixel, and the white sub-pixel.
As shown in fig. 2 and fig. 5-10, only four repeating units are exemplarily shown in the pixel array of the display panel, that is, two first repeating units 11 and two second repeating units 12 are included, and an embodiment of the present invention further provides a display panel, and fig. 11 is a top view of another display panel provided by an embodiment of the present invention, referring to fig. 11, which includes a display area 100 and a non-display area 200 surrounding the display area 100, wherein a pixel array composed of a plurality of first repeating units 11 and a plurality of second repeating units 12 is located in the display area 100, and the repeating units in the pixel array compose a display screen according to the assigned positions and color values. As shown in the figure, preferably, in the pixel array, the color sub-pixels of the first repeating unit 11 are arranged in the order of white sub-pixel, yellow sub-pixel and blue sub-pixel, and the color sub-pixels of the second repeating unit 12 are arranged in the order of red sub-pixel, green sub-pixel and blue sub-pixel. Also, in the display panel, the minimum repeatable unit 13 is composed of four repeating units in which two adjacent rows and two adjacent columns are overlapped with each other, and includes two first repeating units 11 located at diagonal positions and two second repeating units 12 located at the other two diagonal positions.
Fig. 12 is a schematic structural diagram of a display device according to an embodiment of the present invention, and referring to fig. 12, the display device 1 includes any one of the display panels 2 according to the embodiment of the present invention. Since the display device adopts the display panel provided by the above embodiment, the display device also has the beneficial effects of the display panel.
