Description

technical field [0001] The present invention relates to an analog snubber circuit, and more particularly to an analog snubber circuit using a common electrode. Background technique [0002] A display panel generally has a substrate and a plurality of pixel elements formed thereon. These pixel elements are basically arranged in a matrix, and the columns of the matrix have gate lines, and the rows of the matrix have data lines. The display panel is driven by a driving circuit including a gate driver and a data driver. The gate driver generates a plurality of gate signals (scanning signals) to act on the gate lines sequentially to turn on the pixel elements column by column. The data driver generates a plurality of source signals (data signals), that is, sequentially sampled image signals, and these signals are transmitted to the data line at the same time, and cooperate with the gate signals to display images on the panel. [0003] In this driving circuit, a multi-stage shi...

Problems solved by technology

Generally speaking, the narrowing of the channel width and length of thin film transistors will reduce the saturation current and impair the stability of thin film transistors.
