Problems solved by technology

[0003] Since the touch circuit board 240 of the above-mentioned conventional touch-type luminous keyboard 200 adopts a commonly used circuit board and has a certain thickness, the thick and heavy touch circuit board 240 does not meet the requirements in terms of lightness and thinness of today's portable electronic devices. , and it is not suitable for large keyboards in terms of cost. Therefore, these shortcomings need to be improved
