Problems solved by technology

However, the current general-purpose integrated circuit output voltage is generally only up to 16V, and the voltage gap felt by the liquid crystal is not enough to drive the electrode spacing greater than 16um, so that the penetration rate of the wider electrode spacing is not good, and it is impossible to use wider electrode spacing. Electrode spacing to further improve the problem of side view color shift

Abstract

A pixel driving circuit is electrically coupled between a first data line and a second data line and between a first scan line and a second scan line, and includes a first switch, a second switch, a third switch, a fourth switch, a liquid crystal capacitor electrically connected between the first switch and the second switch, a first capacitor electrically connected to the first switch, a second capacitor electrically connected to the second switch, a first storage capacitor, a second storage capacitor and at least one switching unit. The first storage capacitor is electrically connected to the third switch and supplied by a reference voltage. The second storage capacitor is electrically connected to the fourth switch and supplied by the reference voltage. The at least one switching unit is used for redistributing charges in the pixel driving circuit.

Description

technical field [0001] The present invention relates to a pixel driving circuit, in particular to a pixel driving circuit with better transparency. 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 wa...
