Abstract

The invention provides an AMOLED drive device which comprises an AMOLED drive circuit, a scanning drive signal source, a data driving signal source and a data driving signal source control module. The AMOLED drive circuit comprises a first semiconductor controllable switch, a second semiconductor controllable switch, an energy-storage capacitor and an organic light-emitting diode; the scanning drive signal source is used for generating scanning drive signals; the data driving signal source is used for generating data driving signals; and the data driving signal source control module is used for controlling the working mode of the data driving signal source. The AMOLED drive device carries out division on gray-scale value of each pixel, thereby reducing data volume of each PWM drive signal, and reducing transmission speed for a drive chip and requirement for storage speed of a storage device.

Description

technical field [0001] The invention relates to the field of electronic display, in particular to an AMOLED driving device. Background technique [0002] Due to the advances in process technology and materials of flat-panel displays, organic light-emitting diodes (AMOLED, Active-matrixorganiclight-emittingdiode) will slowly become the mainstream of future displays. [0003] figure 1 Shown is a conventional AMOLED driving circuit, which includes a first semiconductor controllable switch T1, a second semiconductor controllable switch T2, an energy storage capacitor C1 and an organic light emitting diode D1. One end of the second semiconductor controllable switch T2 is connected to the first control voltage VDD, the other end is connected to the anode of the organic light emitting diode D1, the negative electrode of the organic light emitting diode D1 is connected to the second control voltage VSS, the first semiconductor controllable The source of the switch T1 is connected ...
