Active matrix display device, scanning drive circuit and scanning drive method thereof

Abstract

The invention discloses a scanning drive circuit of an active matrix display device, the active matrix display device and a scanning drive method of the active matrix display device. The scanning drive circuit comprises a delay module, wherein the input end of the delay module receives input signals is formed by initial clock pulse signals and start pulse signals in an integrated mode, delays the input signals in a two-part mode, enables a first output end to output enable control signals and enables a second output end to output the delay clock pulse signals. Therefore, the active matrix display device, the scanning drive circuit and the scanning drive method of the active matrix display device can reduce the number of transmission lines, reduces the number of output pins of a sequential control chip and input pins of a scanning drive chip, and reduces the cost of chip encapsulation.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a scanning driving circuit of an active matrix display device, an active matrix display device and a scanning driving method thereof. Background technique [0002] At present, there are three control signals for the scanning driver chip, which are used to control the opening and closing of each row of the active matrix display device, which are the start pulse signal (start voltage pulse, STV), the clock pulse signal (clock voltage pulse, CKV) and enable control signal (output enable, OE). see figure 1 , figure 1 It is a schematic diagram of the waveform of the scanning drive in the prior art. Such as figure 1 As shown, the start pulse signal STV is used to control the start of the first row, the clock pulse signal CKV is used to control the switching frequency of each row, and it starts to act when the rising edge of the start pulse signal STV is detected, enabling the cont...
