Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Embodiment 1:
As shown in figure 1, figure 2, figure 3, figure 4 and figure 5, a kind of touch sensible charactron provided by the invention, including charactron modeling
Rubber shell 1 is equipped with charactron pcb board 2 on charactron plastic casing 1, is equipped in the front of charactron pcb board 2 according to the figure of eight point
7 LED luminescence chips 3 of cloth are equipped with 10 pins 4 on charactron pcb board 2, and it is conductive that output is equipped on each pin 4
Electrode 5, and wherein 7 pins 4 are connect with the negative pole end of 7 LED luminescence chips 3 respectively, one of pin 4 and all LED
The positive terminal of luminescence chip 3 is connected to digital input terminal I, removes 7 LED luminescence chips 3 in the front of charactron pcb board 2
Full wafer is equipped with one layer of copper sheet conductive layer 6 at position, and the copper sheet conductive layer 6 is connect with a pin 4 of charactron pcb board 2
