Because the color film of the first pixel is a transparent color film, the corresponding backlight transmittance is the largest relative to a non-transparent color film, the area of the first pixel is set to be the smallest, namely the area of the pixel opening area corresponding to the transparent color film is the smallest, the light transmission amount is less, and meanwhile, the area of the pixel corresponding to the non-transparent color film is increased, so that the transmitted light is increased, and the color cast problem caused by too much light output of the pixel corresponding to the transparent color film is avoided.

Detailed Description
As described in the background section, the display panel in the prior art is prone to color shift, and has a problem of large power consumption of the backlight module.
The inventors found that the reason for the above phenomenon is specifically: fig. 1 is a schematic diagram of a display panel in the prior art; the display panel comprises a backlight module (BL)01 and a Color Film (CF) substrate 02 which are arranged oppositely, wherein a black matrix 03 is arranged on the color film substrate 02, an opening of the display panel is formed by a hollow part of the black matrix 03, and a color film and a transparent color film with different colors are arranged at the opening position of the black matrix 03, so that different pixels emit different lights to form a display picture.
One design of a display panel in the prior art is: the backlight module 01 adopts a blue backlight, and color films arranged in an opening of the black matrix 03 comprise a red quantum dot color film 021, a green quantum dot color film 022 and a transparent color film 023, wherein the red quantum dot color film 021 excites red light after absorbing blue light, a red pixel is formed at a position corresponding to the red quantum dot color film 021, green light is excited after the green quantum dot color film 022 absorbs blue light, a green pixel is formed at a position corresponding to the green quantum dot color film 022, and a blue pixel is formed at a position corresponding to the transparent color film 023. Because the transparent color film 023 absorbs less blue light, and the red light and the green light are emitted by exciting the red quantum dot color film 021 and the green quantum dot color film 022 by the blue light, the light transmittances of pixels corresponding to the red quantum dot color film 021 and the green quantum dot color film 022 are lower, and the light transmittances of pixels corresponding to the transparent color film are higher, so that the whole picture is displayed to be bluish, and the color shift problem is caused.
Accordingly, the present invention provides a display panel comprising:
the pixel array comprises a plurality of pixels arranged in rows and columns, a plurality of data lines extending along the column direction and a plurality of scanning lines extending at least along the row direction;
the plurality of pixels includes a first pixel, a second pixel, and a third pixel; wherein,
the first pixel and the second pixel are positioned in the same column and are connected with the same data line;
the first pixel comprises a first transparent color film, the second pixel comprises a second non-transparent color film, and the third pixel comprises a third non-transparent color film;
the area of the first pixel is smaller than that of the second pixel, and the area of the third pixel is larger than that of the second pixel.
The display panel provided by the invention sets the area of the first pixel to be the minimum, namely the area of the pixel opening area corresponding to the transparent color film is the minimum, the light transmission amount is less, and simultaneously, the area of the pixel corresponding to the non-transparent color film is increased, so that the transmitted light is increased, the color cast problem caused by too much light output amount of the pixel corresponding to the transparent color film is avoided, and simultaneously, the area of the pixel corresponding to the non-transparent color film is increased, so that the integral transmittance of backlight is increased, the brightness of the backlight module can be reduced, the power consumption of the backlight module is further reduced, and the display panel can meet the technical development.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 2 and fig. 3, fig. 2 is a schematic top view of a display panel structure according to an embodiment of the present invention; fig. 3 is a schematic top view of another display panel structure according to an embodiment of the invention. An embodiment of the present invention provides a display panel, including a plurality of pixels arranged in rows and columns, a plurality of Data lines Data extending along a column direction (i.e., Y direction in fig. 2 and 3), and a plurality of scan lines Gate extending at least along a row direction (i.e., X direction in fig. 2 and 3); the plurality of pixels includes a first pixel P1, a second pixel P2, and a third pixel P3; the first pixel P1 and the second pixel P2 are located in the same column and connected to the same Data line Data; the first pixel P1 includes a first transparent color film, the second pixel P2 includes a second non-transparent color film, and the third pixel P3 includes a third non-transparent color film; the area of the first pixel P1 is smaller than that of the second pixel P2, and the area of the third pixel P3 is larger than that of the second pixel P2.
In order to illustrate the difference between the non-transparent color film and the transparent color film in this embodiment, in fig. 2 and fig. 3, the transparent color film is set to be in an unfilled mode, and the non-transparent color film is set to be in a filled slash mode.
Optionally, in this embodiment, the area of the first pixel is 0.3 to 0.7 times, inclusive, of the area of the third pixel, and the area of the second pixel is 0.7 to 1 times, inclusive, of the area of the third pixel, inclusive, of the area of the second pixel, exclusive of the area of the third pixel. The inventor finds that, when the area of the first pixel is smaller than 0.3 times of the area of the third pixel, the backlight transmittance of the pixel corresponding to the transparent color film is small, which affects the brightness of the backlight, and the thin film transistor and other structures arranged in each pixel need to occupy a certain area, so the area of the first pixel cannot be too small. When the first pixel area is 0.7 times or more the third pixel area, the effect of increasing the backlight transmittance is not significant.
In this embodiment, the specific arrangement of the first pixel, the second pixel and the third pixel is not limited, and in one embodiment of the present invention, as shown in fig. 2 and 3, the display panel includes a plurality of pixel rows arranged along the column direction Y; each pixel row comprises a first column of pixels and a second column of pixels; wherein the first column of pixels comprises a third pixel P3, and the second column of pixels comprises a first pixel P1 and a second pixel P2; in the row direction X, the first pixel P1 and the second pixel P2 located in the same column overlap with the same third pixel P3, respectively.
As shown in fig. 2 and 3, the specific arrangement of the first pixel P1, the second pixel P2, and the third pixel P3 is not limited in this embodiment. It should be noted that, in the present embodiment, only the area of the first pixel P1 is limited to be smaller than the area of the second pixel P2, and the area of the second pixel P2 is limited to be smaller than the area of the third pixel P3, so how to realize that the area of the first pixel P1 is smaller, and the area of the third pixel P3 is larger, which is not limited in the present embodiment.
In one embodiment of the present invention, the plurality of pixels may be rectangular in shape, and the first, second, and third pixels P1, P2, and P3 may be arranged to have the same width and different length, so that the areas of the respective pixels are different. In the present embodiment, as shown in fig. 2, the length in the row direction X direction is defined as the width W of the pixel; the length in the column direction Y direction is defined as the length L of the pixel. As shown in fig. 2 and 3, the width of the first pixel P1 is the same as the widths of the second pixel P2 and the third pixel P3, the length of the third pixel P3 is larger than that of the second pixel P2, and the length of the second pixel P2 is larger than that of the first pixel P1.
In another embodiment of the present invention, the first pixel P1, the second pixel P2 and the third pixel P3 have different widths and lengths, which is not limited in this embodiment. The shape of the plurality of pixels may be other shapes such as a polygon and a circle, which is not limited in this embodiment.
In an embodiment of the present invention, the first transparent color film corresponds to the blue pixel, the second non-transparent color film and the third non-transparent color film are quantum dot color films, respectively, the backlight employs a blue backlight, and the red quantum dot color film is excited by the blue backlight to emit red light, and the green quantum dot color film is excited to emit green light. That is, in the embodiment of the present invention, the first pixel is a blue pixel, the second pixel is a red pixel, and the third pixel is a green pixel, or the first pixel is a blue pixel, the second pixel is a green pixel, and the third pixel is a red pixel. Specifically, whether the pixel with the largest area is the red pixel or the green pixel is set according to actual requirements, for example, when the green transmittance does not meet the actual requirements and the red pixel can meet the actual requirements, the green pixel can be set as the pixel with the largest area, that is, the green pixel is the third pixel and the red pixel is the second pixel. When the transmittance of the green pixels meets the actual requirement and the transmittance of the red pixels does not meet the actual requirement, the red pixels can be made to be larger than the green pixels, so that the red light emitting amount is improved, and the actual requirement is met.
It should be noted that, since the first Pixels and the second Pixels are located in the same column and connected to the same data line, one data line can be reduced compared to the standard RGB pixel arrangement in the prior art, so as to reduce the area occupied by the data line, so as to provide more Pixels, thereby improving the PPI (pixel Per inc, the number of Pixels Per Inch, also referred to as pixel density) of the display panel.
In this embodiment, the extending direction of the data lines is the column direction Y direction, but the extending direction of the scan lines is not limited in this embodiment, at least one scan line extends along the row direction X direction, and other scan lines can be adaptively adjusted according to the arrangement mode of the pixels.
