An output buffer, gate drive circuit and control method thereof

Abstract

The present disclosure discloses an output buffer, a gate electrode driving circuit and a method for controlling the same. The output buffer includes a first transistor, a second transistor and an input signal control unit. The input signal control unit controls an input signal to obtain a pull-up signal and a pull-down signal, which are input to input terminals of the first transistor and the second transistor, respectively. The above output buffer uses the input signal control unit to divide one input signal into two signals, i.e., the pull-up signal and the pull-down signal.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an output buffer, a gate drive circuit and a control method thereof. Background technique [0002] In digital integrated circuits, buffers are generally divided into two types: input buffers and output buffers. The input buffer temporarily stores the data sent by the peripheral so that the processor can take it away; the output buffer is used to temporarily store the data sent by the processor to the peripheral. [0003] The connection diagram of the commonly used output buffer is as follows: figure 1 As shown, the CMOS buffer is composed of an even number of inverters, and the device size of each stage is enlarged to improve the driving load capability of the buffer. The output P of the input signal IN and CK after passing through the two-input NAND gate is used as the input of the output buffer, and the output buffer includes two transistors, the first transist...

Problems solved by technology

However, when the width-to-length ratio of the device is large, the conduction current will also become large, resulting in a large corresponding short-circuit current power consumption, and a large proportion in the overall power consumption.
