Title:
VEHICLE-MOUNTED DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/159490
Kind Code:
A1
Abstract:
A vehicle-mounted display device, comprising a display panel (1), which comprises a display surface and a non-display surface opposite the display surface; a metal backboard (2), which is arranged on the side where the non-display surface is located, the metal backboard (2) being grounded; and a circuit board assembly (3), which comprises a first circuit board (31) located on the side of the metal backboard that is away from the display panel, wherein the first circuit board is in signal connection with the display panel by means of a first flexible circuit board, and comprises a first front surface opposite the metal backboard, and a first back surface facing the metal backboard; the first front surface is provided with a circuit pattern; at least one surface of the first circuit board is provided with a first copper exposure region; and the first copper exposure region is electrically connected to the metal backboard by means of a first conductive mechanism. By means of the vehicle-mounted display device, the influence of electromagnetic interference on components on the circuit board can be avoided, thereby solving the problems of the display panel showing a white screen and black screen at some frequency bands. In addition, the display device is easy to manufacture, thereby avoiding the problem of increased costs.
