OLED panel, manufacturing method and device thereof, and OLED display device

Abstract

The application discloses an OLED panel, its manufacturing method, device and OLED display device. The OLED panel includes: a substrate and a plurality of sequentially arranged RGB three-color sub-pixels formed on the substrate, wherein the plurality of sequentially arranged RGB three-color sub-pixels are provided with a plurality of RGB liquid outlets on the surface The cylinder is rotated and printed following the moving speed of the substrate; the arrangement of the plurality of RGB liquid outlets is the same as the arrangement of at least one cycle of RGB three-color sub-pixels on the substrate. In this application, the RGB three-color sub-pixels are simultaneously printed on the substrate in a letterpress printing manner, so as to maximize the utilization rate of the organic light-emitting paint forming the sub-pixels, simplify the production process and cycle, and improve production efficiency.

Description

technical field [0001] The present application relates to the field of display panel manufacturing, in particular to an OLED panel and its manufacturing method, device, and OLED display device. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) displays are famous for their thinness, active light emission, fast response speed, wide viewing angle, rich colors and high brightness, low power consumption, and high and low temperature resistance. It is recognized by the industry as the third generation of display technology after liquid crystal display (LCD). Active OLED (ActiveMatrix OLED, AMOLED) is also called active matrix OLED. AMOLED can realize large size and high The resolution panel is the focus of current research and the development direction of future display technology. [0003] In the prior art, most of the industry adopts evaporation technology to form sub-pixels on the OLED panel. However, evaporation technology ...

AI Technical Summary

Problems solved by technology

However, evaporation technology requires many complex processes to form qualified panels, and this technology requires supporting equipment for making screens. The investment in supporting equipment is large, the manufacturing process is relatively complicated, and the quality of screens is difficult to control. Cleaning the panel also requires a special cleaning machine, and the cleaning is also quite complicated

Complicated multiple processes, difficult to control the quality of the screen, and complex cleaning, these problems have resulted in a low yield rate of products obtained by forming sub-pixels on the substrate by evaporation technology, and a low utilization rate of organic light-emitting coatings that form sub-pixels. The production cycle is long and the production efficiency cannot be improved, which has a great impact on the mass production of OLED panels
