Embodiment Construction

[0026] The light transmittance of OCB liquid crystal depends on the electric field applied to the liquid crystal. When the electric field applied to the liquid crystal changes before the liquid crystal starts to react, the liquid crystal is affected by the viscosity coefficient and elastic coefficient of its own material, and its alignment direction will be affected by the change of the electric field. In other words, the alignment of the liquid crystal is determined by the average value of the moment of the electric field applied to the liquid crystal per unit time, and the above moment is proportional to the square of the electric field, because the light transmittance is related to the arrangement of the liquid crystal, so The light transmittance is related to the root mean square value of the driving voltage. Its formula is as follows:

[0027] V RMS = { ∫ 0 ...

Abstract

The invention discloses a pixel structure, comprising a substrate, an insulation layer, a protective layer, a pixel electrode, a common voltage connecting line and a selecting line, wherein the insulation layer is formed on the substrate, the protective layer is arranged on the insulation layer, and the pixel electrode is arranged on the protective layer, the common voltage connecting line and theselecting line are arranged between the substrate and the insulation layer, the common voltage connecting lien and the pixel electrode form a storage capacitor, the selecting line and the pixel electrode form a coupling capacitor. Because of that a liquid crystal capacitor obtains a pulse signal from the coupling capacitor, the mean square root of the pixel voltage is higher than a threshold voltage, the white-state voltage can be closer to the threshold voltage, therefore the light transmittance of liquid crystal at white picture is improved.

Description

[0001] This application is a divisional application of the Chinese patent application with the application number "200710106333.2", the application date is May 15, 2007, and the invention title is "Optical Compensation Bending Mode Liquid Crystal Display Pixel and Its Driving Method" technical field [0002] The present invention relates to an Optically Compensated Bend Mode Liquid Crystal Display (OCB LCD), and in particular to a pixel structure of an Optically Compensated Bend Mode Liquid Crystal Display. Background technique [0003] In order to match the modern life style, the volume of video or image devices is becoming thinner and lighter. Although the traditional cathode ray display (CRT) still has its advantages, due to the structure of the internal electronic cavity, the display is bulky and takes up space, and there are still problems such as radiation damage to the eyes when displaying. Therefore, the flat panel display (Flat Panel Display), such as liquid crystal...
