Liquid crystal display device and manufacturing method as well as detection and improvement device thereof

Abstract

The invention provides a liquid crystal display device and a manufacturing method as well as a detection and improvement device thereof. The liquid crystal display device comprises a substrate, a pixel electrode and a common electrode, wherein the pixel electrode and the common electrode are arranged on the substrate and are spaced by a first distance; and the liquid crystal display device further comprises a sensing capacitor arranged on the substrate, wherein the sensing capacitor comprises a first electrode and a second electrode which are arranged on the substrate, and the first electrode and the second electrode are spaced by a second distance associated to the first distance. In the invention, by arranging the sensing capacitor on the liquid crystal display device, the capacitance of the sensing capacitor can be detected conveniently, and gamma regulation is facilitated, so that the influence of dimensional change to the transmissivity of the liquid crystal display device is ameliorated and the identical display effect can be achieved by different displayer individuals.

Description

technical field [0001] The present invention relates to a display device, in particular to a liquid crystal display device and a manufacturing method, a detection device and a method for a liquid crystal display device, and a device and method for improving the transmittance of a liquid crystal display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has the advantages of low voltage, low power consumption, large amount of displayed information, easy colorization, etc., and has been widely used in electronic computers, electronic notebooks, mobile phones, cameras, high-definition televisions and other electronic devices. The device's display unit. Unlike cathode ray tubes or plasma display devices, liquid crystal panels do not emit light by themselves, but rely on controlling the reflection and transmission of external light to form different contrasts to achieve display purposes. In the prior art, the liquid crystal molecules defle...

Problems solved by technology

[0006] However, there will be certain deviations in the production process in the process of mass production of displays, which will cause deviations between the actual structure of some displays and the standard structure, resulting in differences in the transmittance of these displays

At this time, if this technical problem is to be solved, the structure of the display device needs to be changed, or the finished product with errors should be discarded, and a new display device should be remade, which greatly increases the production cost of the display device.
