<p>Disclosed is a light guide circuit board module for an illuminating keyboard of a laptop, which comprises a three-layer structure or a two-layer structure. The three-layer structure comprises an upper-layer circuit board, a spacer layer and a lower-layer circuit board which are arranged in sequence from top to bottom, wherein illuminating LEDs are stuck in the upper-layer circuit board; the spacer layer or the lower-layer circuit board is a light guide plate; and circuitry which functions as keyboard keys is printed on the lower-layer circuit board. The two-layer structure comprises an upper-layer circuit board and a lower-layer circuit board, wherein illuminating LEDs are stuck in the upper-layer circuit board; the lower-layer circuit board is a light guide plate; and circuitry which functions as keyboard keys is printed on the lower-layer circuit board. The present invention can avoid the increased laptop thickness caused by the purpose of obtaining a laptop keyboard illuminating function, thereby providing a guarantee for achieving an extra-thin laptop design for keyboard components.</p> |
