[0009] The inner walls of the iron frame and the plastic frame are precisely polished with grinding equipment to avoid light leakage from the backlight layer. At the same time, the molds supporting the iron frame and the plastic frame are high-precision molds, which make the connection process between the plug-in board and the plug-in seam tighter and better in preventing light leakage.

[0010] In a preferred solution, an end cover is provided on an outer wall of one side of the iron frame, and symmetrically distributed heat dissipation holes are provided on both sides of the outer wall of one side of the end cover, and the heat dissipation holes are used in conjunction with the backlight layer.
