Description

Wood grain display module assembly Technical Field The utility model mainly relates to the technical field of vehicle-mounted display screens, in particular to a wood grain display module. Background With the rapid development of the automobile industry, especially new energy automobiles, the design of automobile interiors is increasingly focused on intelligence and aesthetic properties. Conventional large screen display devices, while powerful, may destroy the overall feel and aesthetics of the interior trim. Therefore, the display structure of the vehicle-mounted wood grain decorative cover plate module is provided. The design looks like a wood veneer when not in use, integrates with automotive interior, is attractive and elegant, can display driving information and the like through a display area when in use, and has practicability and attractive appearance. Partial wood grain module, such as the wood grain module used for display screen decoration, has limited light transmittance, so that the decoration effect appears darker, and is not bright and clear enough. In the occasion that needs the printing opacity in order to demonstrate pattern, characters or light effect, such as motormeter dish plaque etc., lower luminousness can influence pattern, characters or light's display effect. Disclosure of utility model The utility model mainly provides a wood grain display module for solving the technical problems in the background art. The technical scheme adopted for solving the technical problems is as follows: The wood grain display module comprises a wood grain cover plate, an optical transparent adhesive tape, a flexible circuit board binding glass, an ultra-strong acrylic foam tape, a backlight module and a back plate, wherein the wood grain cover plate is bonded with the flexible circuit board binding glass through the optical transparent adhesive tape, the flexible circuit board binding glass is connected with the backlight module through the ultra-strong acrylic foam tape, the backlight module is connected with the back plate through another layer of ultra-strong acrylic foam tape, the wood grain cover plate is located at the outermost layer of the module and used for displaying wood grain appearance and has light transmittance, and the back plate is located at the innermost layer of the module and used for supporting and protecting internal structures. Further, the thickness of the wood grain cover plate is between 0.5 and 3 millimeters. Furthermore, the optical transparent adhesive is a base material-free double-sided adhesive, the thickness is between 0.05 and 0.5 millimeter, and the light transmittance is not lower than 95 percent.
