Abstract

The invention relates to an active organic LED display making method, firstly providing a base plate with a luminous region and a nonluminous region, pixel structure formed in the light region; then forming a drive circuit in the nonluminous region, the drive circuit connected with the pixel structure; then setting a cap above the base plate and gluing the cap on the base plate, wherein the cap covers the luminous region and exposes the drive circuit. It can directly test or repair the drive circuit.

Description

technical field [0001] The present invention relates to a flat panel display and its manufacturing method, and in particular to an active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode, AMOLED) display and its manufacturing method. Background technique [0002] An organic light-emitting diode is a photoelectric element that can convert electrical energy into light energy and has high conversion efficiency. Its common applications are indicator lights, display panels, and the like. Due to the characteristics of organic light-emitting diode devices, such as no viewing angle, simple manufacturing process, low cost, high response speed, wide operating temperature range and full color, etc., which meet the requirements of display characteristics in the multimedia era, it has become a research boom in recent years. [0003] An active organic light emitting diode is currently under active development. An organic light emitting layer and a cathode la...
