Abstract

The embodiment of the invention provides a driving circuit and a display device, the driving circuit comprises an integrated power supply management circuit and a source electrode driving circuit, the source electrode driving circuit comprises a positive frame amplifier and a negative frame amplifier, the input end of the positive frame amplifier is connected with the integrated power supply management circuit, and the output end of the positive frame amplifier is used for outputting a positive polarity driving signal during positive frame driving; the input end of the negative frame amplifier is connected with the integrated power management circuit, and the output end of the negative frame amplifier is used for outputting a negative polarity driving signal during negative frame driving; and at least one of the positive frame amplifier and the negative frame amplifier is an adjustable amplifier with an adjustable voltage conversion rate, and the source electrode driving circuit is configured to improve or reduce the voltage conversion rate of the adjustable amplifier according to the charging difference of the positive frame driving and the negative frame driving. According to the design, the charging difference of positive frame driving and negative frame driving can be balanced by adjusting the voltage conversion rate of the adjustable amplifier, and the charging rates of positive and negative frames can be balanced even under the condition that the charging time is relatively short, so that the problem of generation of residual images can be avoided.

Description

technical field [0001] The embodiments of the present application relate to the technical field of liquid crystal display devices, and in particular to a source driving circuit, an array substrate and a display device. Background technique [0002] In the liquid crystal display panel, a voltage difference is formed between the pixel electrode and the common electrode, and the voltage difference controls the rotation of liquid crystal molecules in the form of an electric field, thereby controlling the transmittance of light, so as to realize the display of different gray scales. If the data signals of the same polarity are always applied to the pixel electrodes, the liquid crystal molecules are likely to be polarized, which is easy to cause image sticking. applying a positive polarity data signal and a negative polarity data signal; [0003] However, with the increase of the frame rate of the display panel, the charging time is getting shorter and shorter, which is prone to ...
