Abstract

The invention provides an AMOLED drive method, and the method comprises the steps: enabling the gray scale value of each pixel of each picture frame to be divided into n parts, so as to obtain n PWM drive signals of an organic light-emitting diode, wherein n is a positive integer which is greater than or equal to one; enabling the drive time of each picture frame of the organic light-emitting diode to be divided into n sub drive time parts; enabling n sub drive time parts of each picture frame to be corresponding to PWM drive signals in a one-one manner; enabling all PWM drive signals of each picture frame to be transmitted to the organic light-emitting diode in the corresponding sub drive time part, so as to carry out picture display drive. The method provided by the invention divides the gray scale value of each pixel, thereby reducing the data size of each PWM drive signal and reducing the requirements for the transmission speed of a drive chip and the access speed of a storage unit.

Description

technical field [0001] The invention relates to the field of electronic display, in particular to an AMOLED driving method. 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 ...
