发光键盘、背光模组及发光基板
By forming a protruding structure on the light-emitting substrate, the upper surface of the light-emitting unit is made flush with or lower than the upper surface of the light guide plate, thus solving the problem of inconsistent light emission in existing backlit keyboards and achieving an overall improvement in the consistency of light emission.

AI Technical Summary
Existing backlit keyboards have issues such as overly bright symbols above LEDs, overly dark symbols in the corners of keycaps, inconsistent brightness around keycaps, and inconsistent illumination between single and multiple keys.
A protruding structure is formed on the light-emitting substrate, with the protruding structure corresponding to the light-emitting unit. The upper surface of the light-emitting unit is flush with or lower than the upper surface of the light guide plate, which increases the amount of light entering the light guide plate and improves the overall consistency of light emission.
By increasing the amount of light emitted by the light-emitting unit entering the light guide plate, the overall light emission consistency of the backlit keyboard is improved.
