Claim:
1. A flat self-luminous touch switch, comprising: a self-luminous touch unit, including at least one flat self-luminous pixel and a pixel driving interface, wherein the flat self-luminous pixel is implemented by a self-luminous structure selected from a group consisting of EL, PLED, and OLED; and a switch control unit, including a first driving interface and a second driving interface, wherein, the first driving interface is coupled with the pixel driving interface to provide at least one pixel driving signal and transmit a capacitive touch detection signal; and the second driving interface provides an analog switch channel and/or at least one digital output signal according to a detection result of the capacitive touch detection signal; wherein the at least one electrode of each of the at least one flat self-luminous pixel is directly used as at least one capacitive touch sensing element, and wherein the switch control unit performs both a capacitive touch detection procedure and a display procedure, and performs the capacitive touch detection procedure with the at least one flat self-luminous pixel being powered by pre-stored electric energy of an auxiliary capacitor of an interruptible pixel driving circuit to maintain a display status when the switch control unit is disrupted from the at least one flat self-luminous pixel by the interruptible pixel driving circuit.
