Abstract
The embodiment of the invention provides a mask, a silicon-based OLED display panel and a preparation method thereof. The mask comprises a mask body, which comprises an open pore area, wherein the open pore area comprises a plurality of open pores, and the open pores are formed by adopting a laser drilling process. According to the invention, the size of the open pore formed by adopting the laser drilling process is small, the light-emitting layer meeting the size of a light-emitting device in a silicon-based OLED display panel can be formed when the mask is used for masking, then light-emitting layers of different colors can be formed after the light-emitting layer is prepared by adopting the mask, and the silicon-based OLED display panel does not need to be provided with a light filtering layer, so that the light transmittance of the silicon-based OLED display panel is further improved; and correspondingly, normal color display can be ensured without too high light emitting brightness of the light emitting device in the silicon-based OLED display panel, so that the power consumption of the silicon-based OLED display panel is reduced.
Description
technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a mask, a silicon-based OLED display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, the application of organic light-emitting display technology is becoming more and more extensive. Silicon-based organic light-emitting display panels have the advantages of small pixel size and high pixel density, and are widely used in military sites, VR / AR, and autonomous driving. [0003] At present, micro-display technology generally adopts a silicon-based OLED display panel structure with a white light-emitting layer and a color filter. However, due to the low transmittance of the color filter, the light-emitting devices in the silicon-based OLED display panel require higher brightness and performance normal color display. Contents of the invention [0004] The invention provides a mask pla...
