Problems solved by technology

Among them, precision metal masks are used in the traditional manufacturing process, and the mass production process requires 5 to 6 manufacturing processes, which cost a lot of money
In addition, in the traditional process, the method of adding white light and color photoresist is used to realize full-color display, but because of its low efficiency, and the device needs to adopt a stacked structure, the driving voltage of the device is further increased, thereby reducing the power consumption of the device

Abstract

The present application discloses a full-color display device and a manufacturing method thereof. The full-color display device includes a first electrode layer formed on a first substrate; a light-emitting layer formed above the first electrode layer and includes first A light-emitting layer and a second light-emitting layer, the first light-emitting layer includes light-emitting materials of the first color and the second color, the second light-emitting layer includes light-emitting materials of the third color, and the first color, the second color, and the third color form three primary colors; The second electrode layer is formed above the light emitting layer; the color filter layer is formed above the second electrode layer at a position corresponding to the first light emitting layer. Through the above method, the present application can realize full-color display and improve the display ratio of the panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a full-color display device and a preparation method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) is known as the successor to cathode ray tube (CRT) and liquid crystal display (LCD) due to its advantages of fast response, wide temperature range, self-illumination, and flexible display. And the third-generation display technology after light-emitting diodes (LEDs). [0003] With the continuous increase of market demand, the development and production of flexible OLED has become a hot field in the development of the display industry. Due to the increasing requirement of the panel resolution in the market, how to improve the panel resolution is still the bottleneck of the current manufacturing process. Among them, precision metal masks are used in the traditional manufacturing process, and the mass production process requires 5 to 6 manufa...
