Description

Liquid crystal display screen capable of improving display quality

Technical Field

The utility model belongs to the technical field of the liquid crystal display technique and specifically relates to an improve display quality's liquid crystal display.

Background

From the view of different positioning division levels of the display, the liquid crystal display screen also has different types of division, mainly comprising three types of TN (Twisted Nematic), IPS (In-Plane-Switching) and VA (Vertical Alignment multi-quadrant Vertical Alignment). The VA-type display screen also belongs to a soft screen, and the VA panel shows plum patterns only by touching the panel with fingers, and the TN panel shows water ripples. The VA panel is a panel type with more applications in medium and high-end liquid crystal displays, and panel enterprises such as Fushitong, Samsung, Qimei electronics, Youda photoelectricity and the like all adopt the panel technology. The VA type display screen has the characteristics that the tolerance and the contrast are higher, the high contrast of 3000:1 can be achieved, the black and white in the picture are purer, and the problems of light leakage and the like can not occur.

The upper and lower ITO (indium tin Oxide, tin-doped indium Oxide) electrodes of each display block of the conventional VA-type display screen all adopt uniform electrodes, and after power is applied, all liquid crystal molecules of the same display block are parallel to each other, so that the polarization direction of polarized light incident parallel to the liquid crystal molecules will not be deflected and cannot pass through a liquid crystal cell.
