Utility model content
The purpose of this utility model is to provide a kind of touch button device.
Touch button device provided by the utility model, comprise touch-screen, printed circuit board (PCB) and light-emitting diode, described touch button device also comprises the first flexible circuit board, the two ends of described first flexible circuit board are fixed on a printed circuit and are formed a ledge structure, and described light-emitting diode is fixed in described first flexible circuit board.
Described touch-screen is provided with sensing array device, and described light-emitting diode is connected with described sensing array device circuit by the first flexible circuit board.Described touch-screen is provided with protective glass layers, and described light-emitting diode and described protective glass layers lean.Described cover glass is also provided with one deck light guiding film.Described light-emitting diode is arranged in the first flexible circuit board by surface installation technique.Described touch-screen is also provided with the second flexible circuit board be connected with printed board circuit for realizing touch-screen, and described first flexible circuit board and the second flexible circuit board are bound mutually and realizing circuit is connected.
Touch button device provided by the utility model, make light-emitting diode more close to touch-screen, translucent effect is better, between light-emitting diode and printed circuit board (PCB), also leave the space can designing other components and parts, save design space, be conducive to frivolous property and the portability design of electronic equipment.
Accompanying drawing explanation
Fig. 1 is the touch button device structural representation of the existing light-emitting diode set-up mode mentioned in background technology;
Fig. 2 is the structural representation of the touch button device described in the present embodiment.
