TFT-LCD pixel structure

Abstract

The invention relates to a TFT-LCD pixel structure, comprising film transistors, a grid line, a data line and a pixel electrode which are arranged in a pixel area; the grid line is arranged at the middle part of the pixel area and forms a memory capacitor together with the pixel electrode; the data line is arranged vertically corresponding to the grid line and arranged at one side of the pixel area; at least one of the film transistors is arranged at the crossing of the grid line and the data line and connected with the pixel electrode; furthermore, the film transistors have the quantity of two, and both are connected with the pixel electrode. The TFT-LCD pixel structure cancels the common electrode line, forms the memory capacitor by the grid line arranged at the middle part of the pixel area and the pixel electrode, and effectively reduces the relevant badness caused by the common electrode line; furthermore, the TFT-LCD pixel structure forms two film transistors within one pixel area, and the two film transistors are connected with one pixel electrode so that the TFT-LCD pixel structure has the advantages of quick response, high reliability and the like.

Description

Technical field [0001] The invention relates to a thin film transistor liquid crystal display, in particular to a pixel structure of a thin film transistor liquid crystal display. Background technique [0002] Thin film transistor liquid crystal displays (TFT-LCDs) have the characteristics of small size, low power consumption, no radiation, and relatively low manufacturing costs, and occupy a dominant position in the current flat panel display market. At present, with the large-scale development trend of TFT-LCD, the panel size is getting larger and larger, so the probability of various defects in production is also increasing. At the same time, with the increase of the pixel area, the impact of poor pixels on the picture quality is also increasing. Therefore, for large-scale TFT-LCDs, the probability of various defects in production should be minimized, and the reliability of individual pixel work should be improved. [0003] TFT-LCD includes a color filter substrate and an arra...

AI Technical Summary

Problems solved by technology

However, the actual production shows that the common electrode line of the existing TFT-LCD pixel structure causes quite a lot of defects and is difficult to repair

For example, it is easy to cause disconnection of the common electrode line during production, short circuit between the common electrode line and the deleted line, or short circuit between the common electrode line and the data line.

Once the above defects appear, it will be difficult to repair, and the repair success rate is low

In addition, the common electrode line also needs to be equipped with a corresponding common electrode line drive circuit, which also causes a certain degree of cost increase
