Abstract

This invention relates to organic laser light element, which comprises one first organic transistor tube, one second film transistor tube and at least one organic function layer, wherein, the function layer is set between first and second organic film transistor tubes; it exerts voltage on first and second organic film transistor to generate level difference to make the electron move in the function layer to send light.

Description

technical field [0001] The present invention relates to a light-emitting device, and in particular to an organic electroluminescent device (OEL Device) and its pixel structure, pixel array and driving method. Background technique [0002] With the advancement of multimedia, the importance of displays as an interface between humans and computers is increasing day by day. Among them, the flat panel display (FPD) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation has gradually become the mainstream of the market. [0003] The so-called flat panel displays include liquid crystal displays (Liquid Crystal Display, LCD), organic electroluminescent displays, and plasma displays (Plasma Display Panel, PDP). Among them, the organic electroluminescence display has self-luminescence (Emissive), and can be divided into small molecule organic electroluminescence display (small molecule OLED, SM-OLED) and po...
