In some embodiments, the light source mounting station can be formed at the same time as the circuitry is etched on the flexible wiring board 400.

The operation method of the controllable display flexible touch key 10 is as follows:

when a user touches the key touch area, the conductive layer 101 transmits a touch signal to the control panel 500 through the flexible circuit board 400, the control IC of the control panel 500 detects the touch signal, analyzes and sends an execution instruction through a preset program, on one hand, the flexible circuit board 400 controls the light source assembly such as an LED lamp bead to be opened or closed independently, on the other hand, household products execute or cancel the preset action of the character area corresponding to the key touch area, and therefore, the function control of the household products is realized, meanwhile, the display light source is controlled independently, and the controllable display touch function is achieved.
