Problems solved by technology

[0007] There are existing patents that use quantum dots as light-color conversion materials and combine them with blue light-emitting layers to realize a quantum dot light-emitting diode display device and display device. However, it is very difficult to form sub-pixel units of single-color quantum dots at present, although theoretically possible It can be formed by photolithography or printing technology, but the related technology is not yet mature enough for mass production, and it is difficult to achieve high resolution

Abstract

The invention provides a color display device and a manufacturing method thereof. The color display device comprises a color filtering base plate, an OLED base plate and quantum dot encapsulation glue, wherein the color filtering base plate and the OLED base plate are oppositely arranged and are adhered together via the quantum dot encapsulation glue. Triggered by blue light emitted out by the OLED base plate, the red light quantum points and green light quantum points in the quantum dot encapsulation glue emit out red light and green light respectively. After the red light and the green light are mixed with ground blue light, write light is formed. After the white light is transformed via a color filtering sheet, red, green and blue light are formed, thereby achieving color display. The light purity of the quantum points is high and colors can be controlled via diameters of the quantum points, thereby increasing color gamut and improving display quality of the color display device. The color display device is simple to manufacture and easy to operate and the manufactured color display device has quite wide gamut and quite high display quality.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color display device and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) displays have been more and more used in flat panel displays in recent years due to their advantages of thinness, wide viewing angle, fast response speed, and high contrast ratio. Currently, the mainstream OLED technologies include Samsung's AMOLED (Active-matrix organic light emitting diode) technology and LG's WOLED (white OLED) technology. AMOLED forms an RGB three-color light source through mask evaporation to achieve full-color display. WOLED, on the other hand, forms a white light source by evaporating blue and yellow light-emitting layers, and adds an RGB color filter to achieve full-color display. Similar to WOLED, the use of blue-emitting OLEDs combined with light-color conversion materials to produce RGB three-color light is also one of the tec...
