Problems solved by technology

At present, in the process of mass production of AMOLED, due to the immaturity of TFT substrate technology, the yield rate of AMOLED production is low, which restricts the reduction of AMOLED panel cost; on the other hand, the life of OLED light-emitting materials is not as good as Satisfactory, there is still a lot of room for improvement in the life of AMOLED
From a certain point of view, the production yield and lifespan of AMOLED are the bottleneck restricting its large-scale development, and the purpose of the technical solution of the present invention is also to solve the above bottleneck

Embodiment 1

[0024] figure 2 It is a structural schematic diagram of Embodiment 1 of the present invention. As shown in the figure, each pixel unit 100 in the TFT array substrate of the display of the present invention includes a pixel group 2-1, and the pixel group 2-1 consists of an odd sub-pixel 2-2 and an even sub-pixel 2-3 Each pixel body of the odd and even sub-pixels includes a switching TFT, a driving TFT and an OLED device, wherein the odd sub-pixel 2-2 is electrically connected to the odd scanning line 2-4 and the data line 2-6 respectively, and the odd sub-pixel 2 -2 Obtain switching instructions through the odd scan line 2-4, and obtain display data through the data line 2-6 to realize the light-emitting display function; the even sub-pixels 2-3 are electrically connected to the even scan line 2-5 and the data line 2-6 respectively , the even sub-pixels 2-3 obtain switching instructions through the even scanning lines 2-5, and obtain display data through the data lines 2-6 to...

Embodiment 2

[0028] Figure 4 It is a structural schematic diagram of Embodiment 2 of the present invention. As shown in the figure, compared with Embodiment 1, the pixel group 4-1 in this embodiment includes three sub-pixels: A sub-pixel 4-2, B sub-pixel 4-3 and C sub-pixel 4-4, A, B The three sub-pixels A, C are electrically connected to the A scanning line 4-5, the B scanning line 4-6, and the C scanning line 4-7, and at the same time, the three sub-pixels A, B, and C are all electrically connected to the data line 4-8. During the working process of the display, the three sub-pixels A, B, and C emit light in turn, and each completes the display of a frame of image, thereby prolonging the overall life of the display. And only when three sub-pixels in the same pixel group fail at the same time, the display will have permanent dead pixels. Others are the same as embodiment 1.

Abstract

The invention relates to an active matrix organic light-emitting display, in particular to an active matrix organic light-emitting display with alternating working sub-pixels. In the technical scheme of the invention, the purpose on prolonging the integral service life of the display is achieved through dividing each pixel unit in a TFT (Thin Film Transistor) array substrate into two or more sub-pixels and making each sub-pixel alternatively emit light, meanwhile, the probability on the occurrence of permanent dead pixels on the screen can be reduced, and therefore, the product yield is improved.

Description

technical field [0001] The invention relates to an active matrix organic light emitting display, in particular to an active matrix organic light emitting display with alternate working sub-pixels. Background technique [0002] In recent years, flat-panel displays, especially liquid crystal displays (LCDs) and organic light-emitting displays (OLEDs), have been widely used in display terminals such as mobile phones, digital cameras, notebook computers, and flat-screen TVs due to their light weight and small size. Due to its superior brightness, viewing angle performance, response speed and display effect, OLED is recognized as the next generation flat panel display, especially the advantages of active matrix organic light emitting display (AMOLED). AMOLED achieves a light-emitting display function by forming an OLED pixel device on a thin-film transistor (TFT) array substrate. At present, in the process of mass production of AMOLED, due to the immaturity of TFT substrate tech...
