Title:
COMPENSATION CIRCUIT AND ORGANIC LIGHT-EMITTING DIODE DISPLAY
Document Type and Number:
WIPO Patent Application WO/2018/072312
Kind Code:
A1
Abstract:
Provided are a compensation circuit (10) and an organic light-emitting diode display (20), said compensation circuit (10) comprising: a drive switch transistor (T3), used for driving a load; a reset energy-storage element (12), which couples with the to-be-reset terminal of the drive switch transistor (T3); a reset charging circuit (11), which: couples with the reset energy-storage element (12); at least outputs successively a quick-charge signal (Vini_H) and a reset initial signal (Vini) to the reset energy-storage element (12) when the drive switch transistor (T3) is being reset; the quick-charge signal (Vini_H) is used for rapidly charging the reset energy-storage element (12); the reset initial signal (Vini) is used for adjusting to a preset voltage the voltage of the to-be-reset terminal that the reset energy-storage element (12) outputs to the drive switch transistor (T3). The described means enables quick charging of the reset energy-storage element (12), shortens the time to charge the reset energy-storage element (12) during the reset stage, and improves reset efficiency.
