Silicon-based OLED displayer module and its preparation method

Abstract

The invention provides a silicon-based OLED displayer module, which comprises a silicon-based OLED module and a PCB board electrically connected with the silicon-based OLED module; the silicon-based OLED module comprises a transparent packaging layer, a thin film packaging layer, an LED lighting layer and a silicon-based back plate which are orderly distributed from top to bottom; the silicon-based back plate comprises a back plate main body and a driving electrode layer arranged between the OLED lighting layer and the back plate main body; conductive through holes aligned regularly are arranged on the back plate main body, insulation layers are deposited on the surfaces of the conductive through holes, and conductive pillars are arranged in the conductive through holes. The silicon-basedOLED displayer module cancels the Bonding zone of the silicon-based back plate, reduces the dimension of the silicon-based OLED displayer module, improves the composing rate, and further reduces the preparation cost of the silicon-based OLED displayer module.

Description

technical field [0001] The invention relates to a silicon-based OLED display module and a preparation method thereof, belonging to the field of OLED display manufacture. Background technique [0002] Compared with CTR (CathodeRay Tube, cathode ray tube) display or TFT-LCD (Thin Film Transistor-Liquid Crystal Display, thin film transistor liquid crystal display), OLED (Organic Light-Emitting Diode) display has lighter and thinner With features such as appearance design, wider viewing angle, faster response speed, and lower power consumption, OLED displays have gradually attracted people's attention as a next-generation display device. [0003] In the prior art, the conventional preparation method of a silicon-based OLED display module is: preparing an OLED device on a silicon-based backplane integrated with circuits; then, encapsulating the OLED device with a thin film; finally, using a transparent cover plate to encapsulate the thin film. Parallel encapsulation of the OLED ...

Problems solved by technology

[0004] In the prior art, the metal leads are often arranged on the surface of the silicon-based backplane, so when making the OLED layer and the thin film encapsulation layer on the silicon-based backplane, it is necessary to use a metal mask to cover the bonding area of ​​the metal leads to prevent the formation of the OLED layer. And the material of the thin film encapsulation layer is formed into a film in the Bonding area. However, with the continuous development of encapsulation technology, the OLED layer and the thin film encapsulation la
