Title:
DRIVING CIRCUIT OF OLED DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2017/197701
Kind Code:
A1
Abstract:
A driving circuit of an OLED display panel provided with a plurality of control signal output units (10), and a plurality of pixel light-emitting driving units (20) arranged in an array. The plurality of control signal output units (10) respectively receive different feedback control signals (SFB) for reflecting ageing information of organic light-emitting diodes (D1) in different display areas of an OLED display panel. Each control signal output unit (10) outputs an adjustable light-emitting control signal (EM) to a corresponding pixel light-emitting driving unit (20) according to the received feedback control signal (SFB). Therefore, the light-emitting time of the corresponding pixel light-emitting driving unit (20) in a frame picture period is self-adaptively adjusted according to the ageing degree of the OLED, such that the reduction of brightness caused by the ageing of the OLED can be compensated, and the problem of uneven brightness of the OLED display panel is resolved.
