Abstract
The utility model discloses a liquid crystal glazing and disconnect-type liquid crystal instrument display screen that is shaded for car mainly comprises preceding frame, cover plate glass, double faced adhesive tape, optical cement, liquid crystal glazing, die-casting backlight unit, backshell, screw. The liquid crystal glass and the cover plate glass are fixedly connected by optical cement. The cover plate glass is fixedly connected with the die-casting backlight assembly through double-sided adhesive bonding. The front frame and the rear shell are fixedly connected with the die-casting backlight assembly through buckles and screws. There is no direct connection between the die-cast backlight assembly and the liquid crystal glass. The utility model discloses parts such as preceding frame and backshell and die-casting subassembly in a poor light produce the assembly relation, do not directly produce with liquid crystal glazing and be connected. The deformation of the front frame and the rear case is absorbed by the die-cast backlight assembly, and the deformation of the liquid crystal glass is not directly caused, thereby reducing the occurrence of MURA.
Description
Technical Field
The utility model relates to an automobile display screen specifically is a liquid crystal glazing and split liquid crystal instrument display screen is shaded for car.
Background
The liquid crystal instrument display screen is a very important part of an automobile, and a traditional liquid crystal instrument is assembled in an instrument structure or completely attached to cover glass after a whole group of liquid crystal TFT modules of a TFT (thin film transistor) manufacturer are purchased.
The traditional liquid crystal instrument has a single structure, and cannot overcome the deformation transmitted by a front frame, a rear shell, a loading support and the like, so that the problem of the MURA of the display screen cannot be fundamentally solved. At present that high definition, large-screen display show the prevalence, the long-term MURA problem that can't solve of traditional liquid crystal instrument structure seriously influences the demonstration impression and the volume production quality of complete machine.
Disclosure of Invention
The liquid crystal instrument aims to solve the technical problem that the MURA cannot be fundamentally solved for a long time. The utility model provides a liquid crystal instrument display screen structure, through the instrument structure of liquid crystal glazing and backlight unit disconnect-type, reduce the incidence of display screen MURA problem by a wide margin, experience for the better demonstration of user.
The utility model provides a technical scheme that its technical problem adopted is:
a liquid crystal glass and backlight separated liquid crystal instrument display screen for an automobile mainly comprises a front frame, cover plate glass, double-sided adhesive tape, optical adhesive, liquid crystal glass, a die-casting backlight assembly, a rear shell and screws.
The liquid crystal glass is fixedly connected with the cover plate glass in an optical adhesive bonding mode, the cover plate glass is fixedly connected with the die-casting backlight assembly in a bonding mode through the double-faced adhesive, the front frame and the rear shell are fixedly connected with the die-casting backlight assembly through the buckles and the screws, and the die-casting backlight assembly is not directly connected with the liquid crystal glass.
Further, be provided with on the die-casting subassembly in a poor light and detain position, screw post, there are buckle and screw via hole on preceding frame and the backshell, preceding frame and backshell are shaded fixed connection through buckle and screw and die-casting.
Further, the whole instrument display screen is fixed with the vehicle body instrument desk through screws by utilizing the installation characteristics of the die-casting backlight assembly. The stress and deformation of the loading are absorbed by the die-casting backlight assembly and are not directly transferred to the liquid crystal glass.
The beneficial effect of the invention is that,
compare with traditional liquid crystal instrument display screen before, the utility model discloses, parts such as preceding frame and backshell produce the fitting relation with die-casting backlight unit, do not directly produce with liquid crystal glazing and be connected. The deformation of the front frame and the rear case is absorbed by the die-cast backlight assembly, and the deformation of the liquid crystal glass is not directly caused, thereby reducing the occurrence of MURA. From the source, only apron glass passes through the optical cement contact with liquid crystal glazing, through the double faced adhesive tape contact between other parts and the apron to reduce part and liquid crystal glazing's contact, finally reduce the transmission of part deformation to liquid crystal glazing, thereby reduce the MURA problem that whole machine produced by a wide margin, improve display effect.

Detailed Description
Referring to fig. 1 to 5, the assembling relationship between the liquid crystal glass and the backlight separated instrument display screen described in the present invention will be described. The cover plate 1 and the liquid crystal glass 3 are attached together through the optical adhesive 2, the die-casting backlight assembly 5 is bonded with the cover plate glass 1 through the double-sided adhesive tape 4, and the liquid crystal glass 1 and the die-casting backlight assembly 5 are kept away from the space up and down, left and right without rigid contact. The front frame 6 and the rear shell 7 are connected with the die-cast backlight assembly through buckles and screws, and are not assembled with the liquid crystal glass. The deformation of the front frame 6 and the rear shell 7 can be corrected and absorbed by the die-casting backlight assembly 5 with higher strength, the die-casting backlight assembly 5 and the cover glass 1 are only in flexible connection of double-faced adhesive tape, a little deformation of the die-casting backlight assembly can be absorbed by the double-faced adhesive tape and the cover glass 1, and a little deformation of the cover glass 1 can be absorbed by the optical adhesive 2. The deformation of the front frame 6 and the rear case 7 and the loading can be absorbed by the die-cast backlight assembly 5, and the liquid crystal glass cannot generate deformation enough to cause MURA after the layer obstruction and the soft contact buffer. The transmission from each part deformation to between liquid crystal glazing 3 has been solved from the design source, and finally the MURA problem large scale of instrument display screen reduces, and complete machine display effect promotes by a wide margin.
Various modifications and changes may be made by those skilled in the art to the present invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
