Embodiment Construction

[0022] An anti-static device for PDP module repair, which is divided into three parts: the display screen anti-static grounding system, the backplane and PCB anti-static grounding system, and the human body anti-static grounding system. figure 1 Shown:

[0023] A horizontal screen support surface 26 is used as a support during maintenance of the display module, and the conductive cloth 25, the first electrostatic grounding wire 27, the grounding resistor 22 and the earth 23 form an anti-static grounding system for the display screen. The conductive cloth 25 has extremely low on-resistance, and it is a good conductor of electrostatic charge. The connection between the conductive cloth 25 and the first electrostatic grounding wire 27 is by pasting the conductive cloth 25 to the stripped bare wire of the first electrostatic grounding wire 27, and then winding the wire around their connection points to achieve a firm and reliable connection. It is even possible to use an electric sol...

Abstract

The invention discloses an anti-static device and method for repairing a PDP module. Static charge above on a display module is discharged to the ground through a ground wire by using the static charge ground discharging principle so as to reduce accumulation of the static charge on the display module. The invention has the advantages that a display screen anti-static ground system, a backplate and PCB (Printed Circuit Board) anti-static ground system and a human body anti-static ground system are used to discharge the static charge above the display module to the ground, thereby reducing theaccumulation of the static charge when the display module is repaired, reducing the acting time of static voltage and current and effectively reducing damage to the products caused by static electricity; besides, the single static ground wire is directly connected with the ground without connecting with other ground wires, thereby effectively preventing safety accidents such as leakage backflow and guaranteeing personal safety of maintenance personnel.

Description

Technical field [0001] The invention relates to an antistatic device and method for repairing a PDP module. Background technique [0002] The display module needs to be repaired in the process of PDP display module and complete machine manufacturing, research and development test and after-sales service. In the repair process, product protection is the most important part of the repair project. If the product protection is done improperly, the original failure point is repaired, but a new failure is accidentally caused elsewhere. The final product is still not repaired. In this way, product protection engineering is a necessary engineering technology for maintenance engineering. It is one of the key technologies that affect the success or failure of product maintenance, maintenance efficiency and maintenance quality. [0003] Electronic product protection is divided into mechanical impact protection, thermal shock protection, environmental and chemical corrosion protection, ele...
