Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laptop computer technology, specifically a laptop keyboard with built-in lighting function. Background Technology
[0002] A laptop is a portable computer that integrates a display screen, host, keyboard, and other components. Its keyboard is usually located on the C-side of the chassis (i.e., the panel where the keyboard is placed after opening). It consists of keycaps, a support structure, and a PCB circuit board, and is used for input operations. The core of the illumination function of a laptop keyboard with built-in lighting (i.e., a backlit keyboard) is that micro LED beads are soldered on the keyboard PCB circuit board (1-2 corresponding to each key, with more in the larger key area to avoid dark areas). When the beads are powered on, they emit light, which shines through the light-transmitting character areas laser-engraved on the keycaps (non-character areas are shielded from light). At the same time, the PCB board is connected to the laptop motherboard via a ribbon cable to obtain power. Some models also integrate a dimming chip on the motherboard, which supports adjusting the brightness or switching the lighting mode (such as single-color constant light, breathing light effect, etc.) via shortcut keys. The entire module is directly embedded into a reserved groove on the C-side of the laptop, realizing the integration of lighting and input functions.
[0003] The backlit keyboards of current laptops are usually embedded as a whole module on the C-side of the chassis. They are connected to the C-side by clips and fixing screws (some screws are located in the battery compartment or the bottom of the chassis, requiring the bottom cover or even the battery to be removed before they can be accessed). The keyboard module's ribbon cable is directly plugged into the motherboard interface. This makes the disassembly of the keyboard module quite cumbersome and inconvenient. In actual operation, users need to use special tools to pry open the bottom cover and disconnect the battery ribbon cable before they can proceed. Moreover, the ribbon cable itself is relatively thin, and if too much force or the angle is incorrect during disassembly, the ribbon cable can easily be damaged. Once the ribbon cable is damaged, the entire keyboard module may not be able to function properly. Utility Model Content
