Abstract

The invention relates to a display driving circuit, a display panel and a crosstalk elimination method, the display driving circuit comprises a CF substrate common electrode and a source electrode driving circuit, and a feedback line of the CF substrate common electrode is connected with a target gamma voltage output end of the source electrode driving circuit and is grounded through a grounding capacitor. The target gamma voltage output end of the source electrode driving circuit is used for following the voltage of the feedback line of the common electrode of the CF substrate, generating a bright line at the display linear crosstalk position through gamma voltage adjustment, and counteracting the linear crosstalk. The feedback line of the common electrode of the CF substrate is connected with the target gamma voltage output end of the source electrode driving circuit, so that the gamma voltage of the target gamma voltage output end is reduced, and a white line (namely, a bright line is accurately generated at the joint) is generated at the linear crosstalk position until black linear crosstalk at the linear crosstalk position is counteracted; therefore, linear crosstalk which cannot be eliminated in a traditional scheme can be eliminated, and the purpose of high reliability of horizontal crosstalk elimination is achieved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display driving circuit, a display panel and a method for eliminating crosstalk. Background technique [0002] With the rapid development of the display panel field, people's demand for large-size and high-resolution display panels is increasing day by day, and the requirements for the display effect of display panel products are getting higher and higher. Existing research has found that in the display panel, due to the excessive resistance of the common electrode and the excessive coupling capacitance between the common electrode and the data line, the voltage jump on the data line causes the voltage on the common electrode to be unstable, which makes the voltage on the common electrode unstable. The display panel has the problem of horizontal crosstalk, which leads to display problems such as uneven brightness and flickering of the picture, resulting in poor ...
