Description

Organic Light-Emitting Stereoscopic Display

technical field

The invention relates to the technical field of flat panel display, in particular to an organic light-emitting three-dimensional display.

Background technique

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 require a backlight and has the characteristic of self-luminescence. OLEDs use very thin layers of organic materials and glass substrates that emit light when an electric current passes through them. Therefore, OLED displays can significantly save power, can be made lighter and thinner, can withstand a wider range of temperature changes than LCD displays, and have a larger viewing angle. OLED display is expected to become the next-generation flat panel display technology after LCD, and it is one of the most concerned technologies in flat panel display technology at present.

Generally, whether a display can display full color is one of the important bases for testing whether the display is competitive in the market, so many full-color technologies are also applied to OLED displays. At present, the method for producing a full-color OLED display mainly includes a pixel juxtaposition method (RGB side by side), that is, using fine metal mask (FMM) technology to vapor-deposit the color light-emitting layer of each pixel. However, a full-color organic light-emitting display manufactured by pixel juxtaposition usually needs to use multiple fine metal masks to sequentially form a hole transport layer, a color light-emitting layer, etc., and the manufacturing process is difficult to align and the steps are complicated. In particular, when the OLED's PPI (Pixel Per Inch, dots per inch) is higher, the pixel pitch is smaller, and the use of a fine metal mask to evaporate the color light-emitting layer is more likely to cause color mixing problems, resulting in a lower yield.

The technical focus of making high-PPI OLED displays lies in the high-definition metal reticle with fineness and good mechanical stability, and the key to the high-definition metal reticle lies in the arrangement of pixels and sub-pixels. Fig. 1 is a schematic structural diagram of OLED display pixels in the prior art. As shown in Fig. 1, the display includes a plurality of pixels 100, each pixel 100 is composed of a plurality of sub-pixels, and each pixel 100 includes three sub-pixels of R, G, and B. pixel, the B subpixel of pixel (1, 1) is located in the lower half of the pixel, and its G subpixel and R subpixel are located in the upper half of the pixel, and the G subpixel is located on the left, and the R subpixel is located in the Right. The B sub-pixel of the pixel (1, 2) laterally adjacent to the pixel (1, 1) is located in the lower half of the pixel, while its G sub-pixel and R sub-pixel are located side by side in the upper half of the pixel, and the R sub-pixel The pixel is on the left, and the G sub-pixel is on the right, that is, the pixel structure of the pixel (1, 2) and the pixel (1, 1) is horizontally mirrored; the pixel (2, 1) vertically adjacent to the pixel (1, 1) ) is located in the upper half of the pixel, and its G pixel and R pixel are located side by side in the lower half of the pixel, and the G sub-pixel is located on the left, and the R sub-pixel is located on the right, that is, the pixel (2, 1 ) and the pixel structure of the pixel (1, 1) are vertically mirrored; it can be seen from Fig. The structure is the same as the pixel structure of even rows respectively. The sub-pixels of the same color in adjacent rows and/or adjacent columns are arranged together, so that one mask opening can be used during evaporation, that is, one mask opening can evaporate multiple pixels, so that in the opening Under the condition of a certain size, more pixels can be vapor-deposited to increase the pixel density, that is, to improve the resolution of the organic light-emitting display.

However, since the same sub-pixels of four adjacent pixels are arranged together, a jagged phenomenon will occur when displaying an image, which greatly affects the display effect.
