[0007] The PCB board is also provided with a pad area, and the pad area is arranged adjacent to the metal PIN needle.

[0008] It also includes an extension portion, which is disposed on the pad area.

[0009] The extending portion is arc-shaped.

[0010] It also includes an LCD display module, which is connected to the metal PIN needle.

[0011] The LCD display module includes a first glass plate, and the first glass plate is connected to the metal PIN needle.

[0012] The LCD display module further includes a second glass plate, and the second glass plate is disposed on the first glass plate.

[0013] The LCD display module also includes a first polarizer, and the first polarizer is arranged on the first glass plate.

[0014] The LCD display module also includes a second polarizer, and the second polarizer is arranged on the second glass plate.

[0015] The cross section of the hollow area is a rectangular cross section.

[0016] Compared with the prior art, the utility model has at least the following advantages:

[0017] By setting the hollow area and the soldering groove, when replacing the LCD display module, after heating and melting the solder, you only need to push the metal PIN needle into the hollow area to separate the LCD display module from the PCB board. At the same time, no tin slag will remain in the soldering groove, making replacement or installation very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
