Problems solved by technology

The LED light effect control of the current keyboard has an external signal from the control module and is controlled independently. It is separated from the keyboard by a spacer. The control module and the keyboard occupy a certain amount of space on the keyboard, which cannot effectively reduce the thickness of the keyboard, which is not conducive to the product. The development of thinness and miniaturization, while the existing keyboard lines are complex, which also limits the miniaturization of circuit boards

Embodiment

[0017] A keyboard backlight module in this embodiment includes a substrate, and the substrate can be made of PET, PC or PMMA material, and a circuit board is arranged on the substrate, and the circuit board is covered with a light guide plate. There are keyboard keys on the light plate, and light sources (usually LEDs) corresponding to the keys are set under the light guide plate. Through holes for the light of the light source to penetrate are arranged on the light guide plate, so that the keyboard emits light when the keys are pressed down. The structure of the current keyboard backlight module is generally as follows. This embodiment improves the above structure to reduce the overall thickness of the keyboard, so as to facilitate its miniaturization and thinning. details as follows:

[0018] The circuit board adopts a flexible circuit board, figure 1 It is an overall block diagram of the circuit on the flexible circuit board, and the IC chip 1 is integrated on the flexible...

Abstract

The invention discloses a keyboard backlight module, which comprises a flexible circuit board, wherein the flexible circuit board is provided with a uniform data interface; and the flexible circuit board is provided with a plurality of surface-mount LEDs connected in series. The problem of complicated keyboard circuits is solved, the keyboard circuits are simplified and integrated, the space of the whole keyboard is reduced, and the keyboard is thinned; and the design of products is facilitated.

Description

technical field [0001] The invention relates to a backlight module, in particular to a keyboard backlight module in which a keyboard and a control module are integrated. Background technique [0002] The keyboard backlight module is arranged on the back of the keyboard, and is used to provide the required light effect for the keyboard. The LED light effect control of the current keyboard has an external signal from the control module and is controlled independently. It is separated from the keyboard by a spacer. The control module and the keyboard occupy a certain amount of space on the keyboard, which cannot effectively reduce the thickness of the keyboard, which is not conducive to the product. The development of thinning and miniaturization, while the existing keyboard circuit is complicated, also limits the miniaturization of the circuit board. Contents of the invention [0003] In order to overcome the above disadvantages, the purpose of the present invention is to p...
