Display driving method and system and display terminal

Abstract

The invention discloses a display driving method and system and a display terminal, and the display driving system comprises a panel which comprises a plurality of pixel units arranged in an array; the gate driving circuit is used for controlling the on or off of each row of pixel units; the source electrode driving circuit comprises a plurality of source electrode driving units, one source electrode driving unit is used for providing display data for the pixel units located in the same column, and the polarities of the display data provided for the same pixel unit are opposite when adjacent frames are displayed; and the control circuit is connected between the source electrode driving unit and the pixel units, and is used for writing an intermediate voltage into the pixel electrodes of the plurality of pixel units in the corresponding row for pre-charging when one row of pixel units is conducted, and then writing display data into the pixel electrodes of the plurality of pixel units in the corresponding row. The data voltage is provided for the pixel units step by step, so that overhigh instantaneous voltage change is avoided, voltage disturbance to other signals is further avoided, and finally bad residual images are avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display driving method, system and display terminal. Background technique [0002] With the popularization of electronic products, display devices are becoming more and more diversified. Liquid Crystal Display (LCD) has many advantages such as lightness, thinness, energy saving, etc., and is widely used in high-definition electronic equipment. [0003] The panel in the liquid crystal display device includes a pixel array, the pixel array includes a plurality of pixel units, each pixel unit has a first substrate, a second substrate opposite to each other, and liquid crystal molecules located therebetween, the first substrate and the second An electric field is generated between the common electrode on the substrate and the pixel electrode, and the electric field controls the rotation of the liquid crystal molecules, thereby changing the light transmittance of ea...

Problems solved by technology

However, when the positive and negative frame transitions, the polarity change of the display data provided by the source drive circuit to the pixel unit will generate a large instantaneous voltage difference, and then it is easy to disturb the common voltage received in the pixel unit during display, which will cause positive and negative frame The voltage value of the displayed data is uneven during display, and the voltage asymmetry for a long time will further lead to the polarization of the liquid crystal molecules, and finally the afterimage phenomenon will appear
