Title:
PIXEL CIRCUIT, ORGANIC ELECTROLUMINESCENT DISPLAY PANEL AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/101504
Kind Code:
A1
Abstract:
A pixel circuit, an organic electroluminescent display panel and a display apparatus. In a reset and compensation stage, a charging control module (1) of the pixel circuit conducts a data signal end (Data) and a first input end of a reset control module (3), and the reset control module (3) carries out reset processing and reference voltage compensation processing on the control end and the output end of a driving module (2). In a data writing stage, the charging control module (1) writes data signals input by the data signal end (Data) into the first input end of the reset control module (3). In a light-emitting stage, a light-emitting control module (4) conducts the output end of the driving module (2) and the input end of a light-emitting device, the data signals input to the driving module (2) and the reference voltage signals compensated to the driving module (2) are integrated to drive the light-emitting device (5) to emit light. Therefore, the driving current that drives the light-emitting device (5) to emit light is irrelevant to the power voltage signals (VDD), influences on the luminance of the light-emitting device (5) due to attenuation of the power voltage signals input to the pixel circuit are eliminated, and the display effect of the display panel is ensured.
