[0002] The principle of liquid crystal displays (LCDs) is based on the physical properties of liquid crystals. Voltage is used to control the display area; where there is electricity, there is a display, thus allowing graphics to be shown. LCDs are characterized by their thinness, suitability for direct driving of large-scale integrated circuits, and ease of achieving full-color display. They are currently widely used in many fields, including in-vehicle music players, portable computers, digital cameras, and PDA mobile communication tools.

[0003] However, in practical use, it is difficult to see the position of the LCD screen and operate it when the screen is off in low-light environments. There is a need for a structure that can be integrated with the LCD screen to illuminate and indicate the position, thereby improving the practicality and applicability of the LCD screen. Therefore, it is necessary to design a new type of digital LCD screen. Utility Model Content
