Problems solved by technology

[0006] However, since the common electrode is usually set on the frame of the LCD, with the development trend of LCD narrow frame design, the width of the common electrode is becoming narrower and narrower, and the ability to withstand the charge is getting weaker and weaker, and the charge on the data line cannot be completely rapid. Released to the common electrode, it is also easy to cause a delay in the operation of the pixel unit, resulting in flickering, poor crosstalk or electrostatic discharge damage to the LCD

Abstract

The invention relates to the technical field of liquid crystal display. The invention discloses a discharge protection circuit and a display panel; the discharge protection circuit is arranged on thedisplay panel; the display panel comprises a display area and a non-display area; the non-display area comprises a plurality of virtual gate lines; the display area comprises a plurality of data lines; the discharge protection circuit comprises a plurality of virtual gate lines arranged in rows, a plurality of data lines arranged in columns and a plurality of discharge protection units arranged incolumns, wherein each discharge protection unit is provided with a plurality of discharge protection elements, each discharge protection unit is connected with a plurality of virtual gate lines and one data line, and the plurality of discharge protection elements connected with one same virtual gate line form one of discharge paths of the display panel. Therefore, charges on the data lines can bequickly released, working delay of the pixel units is avoided, the conditions of flickering, poor crosstalk or electrostatic discharge damage of a display device are avoided, and meanwhile, the areaof a non-display area of the display panel is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a discharge protection circuit and a display panel. Background technique [0002] Liquid Crystal Display (LCD) occupies an important position in the flat panel display field due to its advantages of lightness, thinness, low power consumption, high brightness and high image quality. Wherein, the array substrate in the liquid crystal display panel of the LCD includes pixel units and data lines, the data lines are connected to the pixel units, and the operation of the pixel units is controlled through the data lines. During the power-off process of the display device, charge accumulation may occur on the data line, resulting in a delay in the operation of the pixel unit, flickering, poor crosstalk, or electrostatic discharge damage to the LCD. Therefore, it is necessary to discharge the charge on the data line through a discharge protection circuit . [0003] The ex...
