The LCD display screen 16 is driven by the main processing module to set a custom screen background or to display internal keyboard information, including but not limited to battery level, backlight brightness, backlight mode, backlight speed, wireless connection status, and input mode, in order to further improve the user experience.

[0036] Furthermore, the broken code screen 15 and LCD display screen 16 are tilted based on ergonomic principles, with a tilt angle range of 10°-45°, to optimize the user's viewing experience and reduce neck pressure during use. At the same time, they can alleviate visual fatigue when using the keyboard for a long time and improve user comfort. The broken code screen 15 and LCD display screen 16 adopt an embedded structure design to avoid screen damage caused by accidental collisions during use, thereby extending the service life of the keyboard.

[0037] Furthermore, the multifunctional keyboard provided by this utility model also includes a key positioning plate 32. The key positioning plate 32 is provided with a plurality of positioning plate insertion holes 321 corresponding one-to-one with the keyboard keys 31. The plurality of keyboard keys 31 are inserted and cooperated with the plurality of positioning plate insertion holes 321, so that the keyboard keys 31 are limited by the positioning plate insertion holes 321 during use, thereby making it less prone to shaking and improving the stability of the keyboard during use.

[0038] Furthermore, the keyboard key 31 includes a keyboard switch 311 and a keyboard keycap 312. The keyboard switch 311 includes an upper keyboard switch 3111 and a lower keyboard switch 3112. The upper keyboard switch 3111 is inserted into the positioning plate insertion hole 321 and extends out of the mounting cavity through the key positioning area 13. The upper keyboard switch 3111 has a switch insertion part, and the keyboard keycap 312 is detachably connected to the switch insertion part, so as to improve the user experience by replacing different keyboard keycaps 312. The lower keyboard switch 3112 is connected to the control PCB board, so that the tablet computer or mobile phone can be controlled to input information by pressing the keyboard key 31. The keyboard keycap 312 is made of double-layer injection molding process, and its surface is coated with... The keyboard features a wear-resistant finish to enhance durability and prevent character fading. The top of the keycaps 312 is recessed, conforming to ergonomic principles to enhance the tactile feel of the keys and improve typing accuracy. LEDs can be installed inside the keyboard switches 311, allowing for different lighting effects depending on the input mode, as adjusted by the keyboard adjustment lever 14. The LED status is displayed on the LCD screen 16 for easy adjustment. The key positioning area 13 has multiple key positioning holes 131 corresponding to the keyboard keys 31. These holes facilitate the extension of the upper keyboard switches 3111 beyond the first keyboard shell 1 for connection to the keycaps 312, improving installation convenience.
