Abstract

The invented structure includes electric current source, data line, scan line, DC voltage signal wire, several storage capacitors, several switch transistors and a drive transistor, in which said several storage capacitors are formed into a series-connection structure, its function is that when the film transistor circuit structure is changed into closed period from opened period, one storage capacitor of them can make the electric potential of junction between several storage capacitors be lowered by means of negative reaction effect and can make the current passed through luminescent component be reduced so as to implement current regulation function.

Description

technical field [0001] The invention relates to an active current-adjustable thin film transistor circuit structure, in particular to a pixel circuit applied to an active light-emitting component and its display array panel. Background technique [0002] Organic Light Emitting Diode (OLED) has self-illumination characteristics, and can display images without a backlight system, and has become the focus of attention in display components in recent years. In addition, OLEDs have many superior optical properties, such as: high contrast, high brightness, wide viewing angle, color saturation, and fast response time. In addition, organic light emitting diodes have the advantages of thinness and low power consumption, so that organic light emitting diodes are widely used in the display field. [0003] The known technology of the display driving mode is a transistor voltage driving circuit structure, and the voltage signal controls two thin film transistors. This voltage driving m...
