FIELD OF INVENTION

The present invention relates to the field of display, and in particular, to a display panel and a display device.

BACKGROUND OF INVENTION

Organic electroluminescent diode (OLED) display has become the mainstream display product on the market due to its flexibility, self-illumination, wide viewing angles, etc. It is praised as the most promising display technology after the liquid crystal display (LCD). OLED light-emitting devices adopt a sandwich structure. Electrons and holes are injected into an organic light-emitting layer when current is applied to both ends, and different organic light-emitting materials emit different colors of light under excitons excitation, thereby the OLED light-emitting devices are applied to various display products.

With the improvement of the standard of living, electronic terminal products have higher requirements for the resolution of display panels, and the 4K and 8K resolutions concepts have been reported successively. Therefore, how to improve a pixel structure of the current display panel has become an urgent problem to be solved. In the conventional OLED panel, the pixel arrangement is mostly arranged by single-substrate RGB. This method requires high mask and evaporation process. The method of improving the resolution of the display panel is mainly by improving the mask and the evaporation process. However, as the requirement for resolution of the product increase, the pixel density becomes greater and greater, a mask and an evaporation process encounter bottleneck. A high-precision mask is easily broken during a stretching process, and color mixing is likely to occur during the evaporation process.

Technical Problem

An object of the present invention is to solve the technical problem that the resolution of the current display panel cannot meet the high-end requirements of a user.

SUMMARY OF INVENTION

To achieve the above object, the present invention provides a display panel, including: a first substrate; and a second substrate disposed opposite to the first substrate; two pixel layers including a first pixel layer and a second pixel layer; wherein the first pixel layer is disposed on a surface of one side of the first substrate; and the second pixel layer is disposed on a surface of the second substrate facing the first pixel layer.

Further, the pixel layers each includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

Further, the red sub-pixel is square; the green sub-pixel is square, and the blue sub-pixel is rectangular.

Further, a side length of the red sub-pixel is equivalent to a side length of the green sub-pixel.

Further, a sum of areas of the red sub-pixel and the green sub-pixel in the pixel layer is equivalent to an area of the blue sub-pixel.

Further, two or more red sub-pixels and two or more green sub-pixels of the same pixel layer are disposed in a same line; a green sub-pixel is disposed between any two adjacent red sub-pixels, and two or more blue sub-pixels of the same pixel layer are disposed in a same line.

Further, the two adjacent red sub-pixel and green sub-pixel of one pixel layer are disposed opposite to the blue sub-pixel of another pixel layer.

Further, the display panel further includes: a first transparent electrode disposed between the first substrate and the first pixel layer; and a second transparent electrode disposed on a surface of the first pixel layer away from a side of the first transparent electrode.

Further, the display panel further includes: third transparent electrode layer disposed on a surface of the second pixel layer away from a side of the second substrate; reflective electrode disposed on a surface of the second pixel layer away from a side of the third transparent electrode layer; and mirror disposed between the second substrate and the reflective electrode.

To achieve the above object, the present invention also provides a display device including the display panel described above.

Beneficial Effect

The present invention provides a display panel and a display device. The display panel includes two pixel layers, a red sub-pixel and a green sub-pixel on any pixel layer can form a pixel unit with a blue sub-pixel of the same pixel layer or another pixel layer. It improves an arrangement of the pixel units, increases the number of pixel units, increases the pixel density per unit area, and significantly improves the resolution of the display device. The highest resolution of the display device of the present invention is twice the resolution of the prior art single substrate display device.
