Title:
OLED DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/148559
Kind Code:
A1
Abstract:
An OLED display device, comprising: an OLED display panel (1) and a first driving circuit (2) electrically connected to the OLED display panel (1), direct current signal lines (12) being provided in a display area (10) of the OLED display panel (1), and a first direct current signal output end (21) and a second direct current signal output end (22) respectively located at two opposite ends of the OLED display panel (1) being provided in a non-display area (20). One of two adjacent direct current signal lines receives signals from the first direct current signal output end (21), and the other receives signals from the second direct current signal output end (22); in this way, in the signal transmission process, the directions of change in impedance on two adjacent direct current signal lines are opposite, so that the display unevenness of two adjacent columns of sub-pixels can be mutually compensated, reducing the impact of a voltage drop of the direct current signal lines on the display uniformity of the OLED display device, and improving the display quality of the OLED device.
