[0007] Furthermore, the optical film includes a brightness enhancement film, a diffusion film, and a reflective film.

[0008] Furthermore, the lamp beads are LED light source type.

[0009] Furthermore, a heat sink is also included. A plug hole is provided on the side of the outer frame. The heat sink is buckled with the outer frame through the plug hole. The surface of the heat sink is provided with heat dissipation holes in the shape of long strips.

[0010] Furthermore, the heat sink is made of aluminum alloy.

[0011] Furthermore, it also includes a protection frame and a glass plate. The protection frame is arranged on a side of the outer frame close to the liquid crystal panel, and the glass plate is embedded in the middle of the protection frame.

[0012] Furthermore, a protective gasket is also included, and the protective gasket is embedded in the socket.

[0013] Compared with the prior art, the utility model has the following technical effects: 1. The device is configured with buckle grooves and snap buckles to allow the outer frame and the liquid crystal panel to be buckled together. The structure is simple, the connection is stable, and it is convenient to disassemble and assemble. The outer frame and the liquid crystal panel are then adhered to each other through the single-sided tape, so that the liquid crystal panel and the outer frame fit closely to ensure the flatness of the device.

[0014] 2. A heat sink is provided on the outer frame so that the heat sink conducts the heat on the device to the surrounding air for heat dissipation, thereby achieving a cooling operation and allowing the device to operate normally for a long time. BRIEF DESCRIPTION OF THE DRAWINGS
