Title:
ACTIVE-MATRIX ORGANIC LIGHT-EMITTING DIODE DISPLAY MODULE
Document Type and Number:
WIPO Patent Application WO/2020/098196
Kind Code:
A1
Abstract:
Provided is an active-matrix organic light-emitting diode (AMOLED) display module. Cathodes of the AMOLED display module are distributed in a display area of an entire panel in a uniformly arranged manner through a second conductive layer, such that a common ground voltage signal (VSS) can be uniformly introduced onto the cathodes; and each OLED assembly can access the consistent common ground voltage signal (VSS) through the cathodes, and thus a difference value between a working voltage (VDD) on each of the OLED assemblies and a voltage of the common ground voltage signal (VSS) is consistent, and the brightness of each of the OLED assemblies can stay uniform, thereby improving the brightness uniformity of the display area of the panel, and improving the display picture quality of the AMOLED display module.
