Description

Technical Field

[0001] The utility model relates to a liquid crystal display module, and more precisely, to a liquid crystal display module with a glue frame protection structure. Background Art

[0002] In the existing liquid crystal display module, the glue frame is arranged on the periphery of the backlight iron frame. Since the glue frame is relatively soft and prone to deformation, static electricity can easily enter from the upper edge, thus affecting the stability and reliability of the liquid crystal display module.

[0003] Chinese invention patent document CN108490665A discloses an inlaid liquid crystal display screen. The inlaid liquid crystal display screen is arranged on a window on the side wall of a sealed cabin. The window includes an inner layer of glass, an outer layer of glass, and a window frame. The inner layer of glass and the outer layer of glass are arranged with a gap therebetween. The window frame surrounds the outer edges of the inner layer of glass and the outer layer of glass, and the window frame is fixedly connected to the side wall. The liquid crystal display screen includes a fixedly connected display area and a bracket. The bracket is fixedly connected to the window frame so that at least a part of the display area extends into the gap between the inner layer of glass and the outer layer of glass, and the liquid crystal panel of the display area faces the inner layer of glass. The display area includes a reflective sheet, a light guide plate, an optical film, a buffer material, and the liquid crystal panel stacked in sequence. The bracket is provided with a light emitting unit, and the light emitting unit faces the light guide plate. A light shielding film is attached to the sides of the light guide plate and the optical film to prevent side leakage of light. A buffer layer is provided between the reflective sheet and the outer layer of glass to achieve buffer protection of the inlaid liquid crystal display screen. The liquid crystal panel is attached to the inner layer of glass to avoid reflection of the light emitted by the liquid crystal panel by the inner layer of glass. An OCA optical adhesive is provided between the liquid crystal panel and the inner layer of glass to achieve attachment of the liquid crystal panel to the inner layer of glass. The window frame is fixedly arranged on the side wall, and the bracket is fixedly connected to the window frame by being fixedly connected to the side wall. The bracket further includes a heat dissipation unit and a control unit. Both the light emitting unit and the control unit are in contact with the heat dissipation unit, and the control unit is electrically connected to the liquid crystal panel. A groove is provided on the bracket for accommodating the light emitting unit, and the opening of the groove faces the light guide plate. A heat dissipation guide bar is provided between the heat dissipation unit and the side wall and / or the window frame.

[0004] Obviously, by disposing the display screen between the inner glass and the outer glass, the patent realizes the inlaid installation function of the display screen. Through the fixed connection between the bracket and the window frame, the fixing and display functions of the display screen are realized, and the liquid crystal display screen can dissipate heat through the bracket and the window frame, and its heat will not be trapped between the inner glass and the outer glass. By arranging the liquid crystal panel towards the inner glass, the inlaid liquid crystal display screen of the present application can be viewed by the people in the cabin. At the same time, both the inner glass and the outer glass provide good protection for the inlaid liquid crystal display screen, making the inlaid liquid crystal display screen of the present application not easily damaged. However, this structure cannot solve the existing problems of the glue rack. Summary of the Utility Model

[0031] As described in the background art, for the liquid crystal display module in the prior art, the glue frame of the existing liquid crystal display module is arranged on the periphery of the backlight iron frame. Since the glue frame is relatively soft and easily deformed, static electricity is also easily introduced from the upper edge, thereby affecting the stability and reliability of the liquid crystal display module.

[0032] To solve this technical problem, the present utility model provides a liquid crystal display module with a glue frame protection structure, which includes an upper iron frame 1 and a backlight iron frame 2.

In addition, since the TFT panel 3 and the glue frame 4 are completely wrapped by the upper iron frame 1 and the backlight iron frame 2, the overall strength of the liquid crystal display module can be effectively improved, and its seismic performance can be improved, thereby effectively improving the reliability of the liquid crystal display module.
