Abstract
Full-color micro-OLED display structure and its preparation process, relating to the technical field of full-color micro-organic light-emitting display devices with silicon wafers as substrates, especially the top-emission full-color micro-OLED display structure and its preparation process formed by laser transfer printing technology, its characteristics The method is to prepare a light-emitting layer by using a laser transfer printing method, and then use it in a full-color micro OLED display. A full-color micro-OLED display structure and its preparation process of the present invention adopts laser transfer printing technology and is applied to the full-color micro-OLED display structure. Compared with the traditional OLED display structure using a color filter layer, the light output rate is obviously improved.
Description
technical field [0001] The invention relates to the technical field of a full-color micro-organic light-emitting display device with a silicon chip as a substrate, in particular to a top-emitting full-color micro-OLED display structure formed by laser transfer technology and a preparation process thereof. Background technique [0002] The OLED display structure has a series of characteristics such as self-illumination, low-voltage DC drive, full curing, wide viewing angle, light weight, large-size and bendable panels, simple process, etc., and has the potential of low cost, which can meet the needs of today's information technology. The era's requirements for higher performance and greater information capacity of display technology have become one of the hottest topics in the scientific and industrial circles. [0003] Micro-OLED display refers to organic light-emitting devices driven by silicon-based CMOS with a display size of less than 1 inch, with pixels up to 800×600 or...
