Vehicle-mounted display screen electrostatic protection structure

Abstract

The invention discloses a vehicle-mounted display screen electrostatic protection structure, and relates to the field of vehicle-mounted display screen electrostatic protection, the vehicle-mounted display screen electrostatic protection structure comprises an LCD display module, a display screen upper cover is arranged above the LCD display module, a display screen rear cover is arranged below the LCD display module, and the display screen upper cover and the LCD display module are bonded through optical cement. A metal conductive layer and a conductive ink layer are arranged between the display screen upper cover and the optical cement, the display screen rear cover is arranged around the bottom and the side face of the LCD display module, and an insulating layer is further arranged in an edge gap between the LCD display module and the display screen rear cover; the LCD display module comprises a light source, a light guide plate, a reflector plate, an optical film, a circuit board and a chip. The metal conductive layer is formed by arranging a circle of metal wire around the edge of the bottom of the display screen upper cover. By arranging the metal conductive layer, the conductive ink layer and the insulating layer, the electrostatic protection capability of the vehicle-mounted display screen is improved, and the problem of splash screen and blurred screen of the display screen caused by static electricity is solved.

Description

technical field [0001] The invention relates to the field of vehicle-mounted display screens, and more particularly, to an electrostatic protection structure for vehicle-mounted display screens. Background technique [0002] As vehicle-mounted displays have higher and higher requirements for display effects, full lamination has become a mainstream technology, and products with narrow bezels are increasingly favored by customers. In the traditional vehicle full lamination technology, the display module (LCD display module) is used to attach the touch screen. The LCD display module contains an upper metal frame or conductive cloth, which has electrostatic protection for the chip of the flexible circuit board and the flexible circuit board. . [0003] However, with the optimization of process and cost, it is a trend to use flexible circuit boards and touch bonding, but this design leads to the lack of metal frame or conductive cloth protection for the chips and circuit boards ...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a vehicle-mounted display screen static protection structure, which has the characteristics of being able to solve the problem of static electricity jumping to chips or circuit boards, causing the display screen to have a flickering screen.
