Problems solved by technology

However, the output voltage of the current general-purpose integrated circuit is only up to 16V, and the voltage gap felt by the liquid crystal is not enough to drive the electrode spacing larger than 16um, so that the penetration rate of the wider electrode spacing is not good, and wider electrodes cannot be used. Spacing to further improve side view color cast

Abstract

The invention discloses a pixel drive circuit and a drive method thereof. The pixel drive circuit is electrically coupled between a first data line and a second data line, and between a first scanning line and a second scanning line. The pixel drive circuit includes a first switch, a second switch, a third switch, a fourth switch, a first sub-capacitor, a second sub-capacitor, a fifth switch, a sixth switch, a first capacitor and a second capacitor. The first capacitor is coupled between the second terminal of the fifth switch and a reference voltage terminal; and the second capacitor is coupled between the second terminal of the sixth switch and the reference voltage for re-distributing storage charge. According to the technology scheme provided in the application, liquid crystal molecules are driven by a stonger electronic field, a larger inclined angle is provided, further better penetration performance is provided, and side visual color deviation is minimized.

Description

technical field [0001] The invention relates to a pixel driving circuit, in particular to a pixel driving circuit for improving pixel transmittance. Background technique [0002] As liquid crystal display devices continue to develop towards large-size display specifications, in order to overcome the viewing angle problem under large-size displays, the wide viewing angle technology of liquid crystal display panels must also continue to improve and break through. At present, technologies that can meet the requirements of wide viewing angle include multi-domain vertical alignment (MVA), multi-domain horizontal alignment (MHA), twisted nematic plus viewing angle expansion film (TN+film) and transverse electric field (In Plane Switching, IPS) . [0003] The liquid crystal display using the technologies listed above can achieve the purpose of wide viewing angle, but there will be a problem of color washout. Generally speaking, the so-called color shift means that when the user w...
