Problems solved by technology

[0003] Before assembling the circuit board, the plasma display panel is in a state of static electricity. The panel with static electricity is working on the production line. On the one hand, the static electricity may cause damage to the equipment and cause certain harm to the operator; The damage and failure of the precision IC bound on the panel affects the quality, life and pass rate of the panel (First Pass Yield (FPY) is an indicator to measure the quality level of the production line, which is used to describe the production quality and work quality. or a certain state of test quality

Abstract

The invention discloses a method and a device for removing residual charge of a display screen, and relates to technology of plasma display. The method mainly comprises steps of manufacturing a brush-shaped structure by utilizing a soft conductive material; installing the brush-shaped structure on a worktable in a display screen production line; grounding the brush-shaped structure; placing the display screen on a conveying mechanism on the worktable; and driving the display screen to pass through the brush-shaped structure by the conveying mechanism. The device basically comprises a brush head, bristles and a grounding conductor, wherein the bristles are made of the soft conductive material and are fixed on the brush head; one end of the grounding conductor is connected with the bristles in a coupled manner; and the other end of the grounding conductor is grounded.

Description

technical field [0001] The invention relates to plasma display technology, in particular to a method and device for removing residual charges on a display screen. Background technique [0002] Plasma display is a kind of display that uses gas discharge to generate ultraviolet rays, and then excites phosphors to emit visible light to display images. Plasma display panel is the main structure to realize discharge and light emission. It is composed of two substrates, front and rear. Composed of horizontal SUS electrodes and SCAN electrodes, as well as a dielectric layer and a dielectric protective film above, the rear substrate is provided with a vertical ADD electrode and a barrier structure, and the discharge is carried out in the space formed by the front and rear substrates and barriers. [0003] Before assembling the circuit board, the plasma display panel is in a state of static electricity. The panel with static electricity is working on the production line. On the one h...
