Problems solved by technology

[0013] The result of the periodic arrangement of pixels is that the blue sub-pixels in the pixel array are arranged in a straight line, so that the corresponding metal mask must use the aforementioned slit or the aforementioned slot opening method, but as mentioned above, the slit and slot opening methods All have defects, which lead to the opening of the blue metal mask in the pixel array arrangement of IGNIS, which seriously affects the further improvement of the sub-pixel aperture ratio and PPI.
[0014] In addition, organic light-emitting display devices generally reduce the aperture ratio of sub-pixels as the resolution increases, resulting in increased operating brightness of monochrome devices and shortened display life.

Embodiment 1

[0069] image 3 It is a schematic diagram of the first embodiment of the pixel structure of the organic light emitting display of the present invention. like image 3 As shown, the display includes a plurality of pixels 300, and each pixel 300 is composed of a plurality of sub-pixels. Each pixel 300 includes an R sub-pixel region 301 , an R light-emitting region 302 , a G sub-pixel region 303 , a G light-emitting region 304 , a B sub-pixel region 305 , and a B light-emitting region 306 . The size of each pixel is H×H.

[0070] In this embodiment, the R, G, and B sub-pixels of each pixel are all quadrilateral, and the sub-pixels are arranged in a "pin" shape or an inverted "pin" shape. The length and width of the R and G sub-pixels are both 1 / 2H, while the B sub-pixel has a width of H and a height of 1 / 2H, that is, the area of ​​the B sub-pixel is twice that of the G sub-pixel or the R sub-pixel.

[0071] Wherein, each pixel unit in this embodiment may be composed of an odd...

Embodiment 2

[0082] like Figure 5 A second embodiment of the invention is shown. In this embodiment, the display includes a plurality of pixels 500, and each pixel is composed of a plurality of sub-pixels. The shape of each sub-pixel is a triangle. Preferably, as Figure 5 As shown, each sub-pixel is an isosceles right triangle, and the right angles of every four sub-pixels are arranged relative to each other to form a pixel. The four sub-pixels constituting one pixel include one R sub-pixel 501 , one G sub-pixel 503 and two B sub-pixels 502 , wherein the two B sub-pixels 502 are disposed opposite to each other. In this way, the area of ​​the B sub-pixel 502 is also twice that of the R sub-pixel 501 or the G sub-pixel 503, thereby ensuring the display effect of the display.

[0083] like Figure 5 As shown, the figure only shows a part of the organic light emitting display, and the number of pixels in an actual product is not limited to this. The first row, the second row, the first...

Embodiment 3

[0094] For Example 2, we can replace some sub-pixels of colors with other colors, such as Image 6 In the illustrated third embodiment of the present invention, each pixel 600 in this embodiment is composed of R sub-pixels 601 , G sub-pixels 603 , B sub-pixels 602 and W (white) sub-images 604 respectively. This example and Figure 5 Compared with the illustrated embodiment, one of the B sub-pixels is replaced with a W sub-pixel 604, and the positions of the R sub-pixel and the G sub-pixel are exchanged. The advantage of this embodiment is that since each pixel includes one W sub-pixel, it can display white more pure and achieve higher brightness.

[0095] Specifically, as Image 6 As shown, the display includes a plurality of pixels 600, each pixel being composed of a plurality of sub-pixels. The shape of each sub-pixel is a triangle. Preferably, as Image 6 As shown, each sub-pixel is an isosceles right triangle, and the right angles of every four sub-pixels are arranged...

Abstract

The invention discloses a pixel structure and an organic light emitting displayer using the same. The pixel structure comprises a plurality of pixels, wherein each pixel is composed of a plurality of sub-pixels, and one or more pixels constitute a pixel unit. Through the reasonable pixel distribution structure, the sub-pixels of every two adjacent pixels share an opening of a Mask for evaporation, the area of the opening of the Mask can be increased during evaporation, the technology manufacturing difficulty of the Mask is lowered, and the evaporation technology difficulty is also lowered. No gap needs to be reserved while evaporation is performed on the sub-pixels of every two adjacent pixels of the Mask, the requirement for the aperture ratio is met, and meanwhile the real high PPI can be achieved. In addition, strength of the Mask can be enhanced through the pixel structure, so that the Mask is not prone to deformation in a use process, the product yield is increased, service life of the Mask is prolonged, and cost is reduced.

Description

[0001] This application is a divisional application for an invention patent application with the application number of 201310747572.1 and the filing date of December 31, 2013, entitled "A Pixel Structure and an Organic Light Emitting Display Using the Pixel Structure". technical field [0002] The present invention relates to the technical field of organic light-emitting display, in particular, to a pixel structure and an organic light-emitting display using the pixel structure. Background technique [0003] OLED (Organic Light-Emitting Diode, organic light-emitting diode) is an active light-emitting device. Compared with the traditional LCD (Liquid Crystal Display, liquid crystal display) display method, the OLED display technology does not need a backlight and has the characteristics of self-illumination. OLEDs use very thin layers of organic materials and glass substrates that emit light when an electric current flows through them. As a result, OLED displays can signific...
