[0018] (III) Beneficial Effects

[0019] One of the above technical solutions has the following advantages or beneficial effects:

[0020] 1) To address the issue that existing capacitive touchscreens are simply glued together, causing debris to easily adhere to the undamaged screen or substrate when one glass component is damaged, making cleaning difficult and potentially scratching the undamaged screen or substrate, thus causing inconvenience, a tempered glass layer is added on top of the touch glass layer for enhanced protection. Protective films made of plastic are also glued to the top and bottom of the touch glass layer to ensure flexibility. This prevents debris from adhering to the touch glass layer or substrate when the tempered glass layer breaks, facilitating subsequent repairs.

[0021] 2) To address the issue that in existing technologies, before the screen is placed in a protective bag or box, or after it has been removed from its protective casing, the sides are easily scratched during storage, transportation, or assembly. This can severely impact the screen's transmission or display performance, causing considerable inconvenience. Additionally, the screen's cables are prone to breakage, rendering the screen unusable. To address this, a side protective layer is provided to wrap the screen and prevent side scratches. A U-shaped protective frame, connected at one end to the side protective layer, wraps both sides of the cables, increasing their protection. During assembly, if the frame and side protective layer need to be removed, the side protective layer can be easily and quickly removed by pulling the frame. Attached Figure Description
