Problems solved by technology

With the improvement of display quality requirements, more and more attention has been paid to full-color organic light-emitting displays. Full-color organic light-emitting displays generally use sub-pixels formed by red light-emitting layers, green light-emitting layers, and blue light-emitting layers to mix colors to achieve For full-color display, resolution and contrast are an important factor in determining the display quality. However, due to the limitation of the organic layer forming process, the improvement of the resolution of the organic light-emitting display has also encountered a bottleneck. Therefore, it is necessary to provide an easy-to-achieve existing process. , a pixel arrangement that can increase resolution and reduce cost

Embodiment 1

[0040] figure 2 It is a schematic diagram of an arrangement of pixel units in a display panel according to an embodiment of the present invention. Please refer to figure 2, each pixel unit contains a sub-pixel whose long axis is along the column direction, its color is blue or white; direction, which is colored red or green). By adding white diamond-shaped sub-pixels, high brightness can be achieved while improving display resolution, and light utilization efficiency can be improved.

[0041] The green resin transmittance is 60%, the red resin transmittance is 18%, and the blue resin transmittance is 6%. For RGB pixel units arranged in three primary colors, and the pixel areas of each color are the same, RGB The total transmittance of the pixel unit is only 1 / 3*60%+1 / 3*18%+1 / 3*6%=28%.

[0042] Please refer to figure 2 , in the direction of each column, RGB pixel units and RGW pixel units are arranged at intervals, because blue gives the darkest visual effect, and the i...

Embodiment 2

[0045] image 3 It is a schematic diagram of arrangement of pixel units in a display panel according to Embodiment 2 of the present invention. Please refer to image 3 , similar to Embodiment 1, in the direction of each column, the RGB pixel units and the RBW pixel units are arranged alternately, wherein the red diamond-shaped sub-pixels (R) and the blue diamond-shaped sub-pixels (B) of the RGB pixel units and the RBW pixel units are arranged In the same way, the green diamond-shaped sub-pixel (G) in the RGB pixel unit is replaced by a white diamond-shaped sub-pixel (W) in the RBW pixel unit. In the two pixel units, the red diamond-shaped sub-pixels (R) and the blue diamond-shaped sub-pixels (B) are arranged at intervals to form sub-pixel columns, and the green diamond-shaped sub-pixels (G) and white diamond-shaped sub-pixels (W) are arranged at intervals with the above-mentioned sub-pixels Columns of adjacent sub-pixel columns. That is, in the RGB pixel unit, the long axis...

Embodiment 3

[0047] Figure 4 It is a schematic diagram of arrangement of pixel units in a display panel according to Embodiment 3 of the present invention. Please refer to Figure 4 , similar to Embodiment 1 and Embodiment 2, in the direction of each column, RGB pixel units and BGW pixel units are alternately arranged, wherein RGB pixel units and BGW pixel units include blue diamond-shaped sub-pixels (B) and green diamond-shaped sub-pixels (G) The arrangement is the same, and the red diamond-shaped sub-pixel (R) of the RGB pixel unit is replaced by a white diamond-shaped sub-pixel (W) in the BGW pixel unit. In the two types of pixels, the blue diamond-shaped sub-pixels (B) and the green diamond-shaped sub-pixels (G) are arranged at intervals to form sub-pixel columns, and the red diamond-shaped sub-pixels (R) and white diamond-shaped sub-pixels (W) are arranged at intervals with the above-mentioned sub-pixel columns Adjacent sub-pixel columns. In the RGB pixel unit, the long axis of th...

Abstract

The invention provides a pixel unit, a display panel applying the pixel unit, a display method and a display device. The pixel unit is formed by splicing three rhombus sub pixels, and every two adjacent rhombus sub pixels are symmetric about the adjacent sides of themselves. The size of the rhombus sub pixels is larger, the rhombus sub pixels can be obtained on an existing production line, and the rhombus sub pixels can be produced through an existing mature technology, so that the product yield is higher, popularization difficulty is small, and the application prospect is wide.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel unit and a display panel using the same, a display method, and a display device. Background technique [0002] In the field of image display, the RGB three-color system is the most widely used color rendering system. In this color rendering system, a pixel unit generally includes sub-pixels of three different colors of red, green and blue. By controlling the sizes of the three color components of RGB corresponding to the three sub-pixels in a certain pixel unit, the Controls the color and brightness displayed by the pixel. Figure 1A It is a schematic diagram of arrangement of RGB pixel units in the prior art RGB three-color system. Where RGB is arranged in rows sequentially, and RGB are arranged in columns respectively. In the direction of the vertical line, since there is only one color in this arrangement, color unevenness is likely to occur, resulting in co...
