Abstract

The invention provides a light-emitting element driving circuit, a pixel circuit, a display panel, and a display. When the frame of the driving circuit (5T1C) is cooperated with a proper operating waveform, the current cross an organic light emitting diode cannot change along the power supply voltage (Vdd) under the influences of current, resistance, and voltage drops, and cannot change along the threshold voltage shift (Vth shift) for driving the thin film transistor of the organic light emitting diode. Therefore, the brightness uniformity of the organic light emitting diode display using the same can be greatly improved.

Description

technical field [0001] The present invention relates to a plane display technology, and in particular to a light-emitting element driving circuit, a pixel circuit, a display panel and a display. Background technique [0002] Due to the rapid progress of the multimedia society, the technologies of semiconductor devices and display devices have also undergone rapid progress. As far as the display is concerned, since the active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode, AMOLED) display has no viewing angle limitation, low manufacturing cost, high response speed (about a hundred times higher than that of liquid crystal), power saving, self-illumination, It can be used for DC drive of portable machines, has a wide operating temperature range, is light in weight, and can be miniaturized and thinned along with hardware devices to meet the characteristic requirements of displays in the multimedia era. Therefore, the active matrix organic light ...
