Problems solved by technology

If the pixel transistor in each pixel unit is damaged, the corresponding pixel unit will not work normally
In addition, if any source line is damaged, it will cause the two rows of pixel units to fail to work normally.

Embodiment Construction

[0026] In the drawings, when an element is referred to as being “connected” or “coupled” to another element, it may be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.

Abstract

The invention provides a pixel structure. The pixel structure comprises a first pixel unit and a second pixel unit. A first data signal of a source electrode driver can be output to the first pixel unit by a first source electrode line and can be output to the first pixel unit by a first control switch and a second source electrode line. A second data signal of the source electrode driver can be output to the second pixel unit by a second control switch and a second source electrode line or by a third source electrode line. As the second source electrode line can be shared by the first pixel unit and the second pixel unit, the pixel structure not only has self-repair function but also reduces the number of source electrode lines.

Description

【Technical field】 [0001] The invention relates to a pixel structure of a liquid crystal display, and in particular to a pixel structure with repairing function. 【Background technique】 [0002] Generally speaking, a flat-panel display is mainly composed of a display panel and a plurality of driver ICs. The display panel has a pixel array, and the pixels in the pixel array are connected by corresponding scanning lines and corresponding data lines. driven by. In order to make flat-panel display products more popular, the industry is in full swing to reduce costs. In recent years, a data-driven chip half source driver architecture design has been proposed, which mainly uses the layout of the pixel array to reduce the cost. Data drives chip usage. [0003] figure 1 is a schematic diagram of a known liquid crystal display. Please refer to figure 1 , the pixel array is described by taking the pixel units P1-P4 as an example. During the first scan period, the gate driver 101 c...
