Embodiment Construction

[0027] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0028] The present invention is aimed at the existing narrow-frame display panel. Since the electrostatic protection design cannot be placed during the design process of the narrow-frame panel, static electricity is easily introduced into the metal wiring around the display panel and the display area to cause electrostatic damage to the device, further affecting the pro...

Abstract

An antistatic display panel and a preparation method thereof are provided. The display panel comprises a display area, and a driving chip fixed on the surface of a flexible circuit board is bound to the lower edge of the display area. A pin on the driving chip is electrically connected with an electrostatic discharge circuit, and the pin forms a closed loop with the electrostatic discharge circuit. The display panel and the preparation method have the advantage that the pin on the driving chip and the electrostatic discharge circuit form the closed loop, thereby effectively protecting an internal signal line of the narrow bezel display panel, further reducing the risk of electrostatic damage to the panel and further increasing the product yield.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an antistatic display panel and a preparation method. Background technique [0002] At present, with the development of mobile display technology towards higher image quality, higher degree of detail, thinner and lower power consumption, display screens need to be cut from large glass into small display screens. Because a large amount of static electricity is easily generated during the cutting process, the static electricity is easily introduced into the peripheral metal wiring of the liquid crystal panel and the display area, causing electrostatic damage to the device, which in turn causes abnormal display, greatly affecting the product yield. Existing COG (chip on Glass, chip bound on glass substrate) products will carry out electrostatic protection design, but as the frame shrinks day by day, so that the display area increases, the traditional electrostatic protection design...
