Identification signal detecting method and apparatus

An identification signal detection method, comprising touch key array controller, and the controller connected to the signal and the antenna array is capable of transmitting a wireless signal; touch key array antenna arrays and signal superposed in the same region and alternately operate respective operation detection signal. An identification signal detecting apparatus including a touch key array controller, and the controller connected to the signal and the antenna array is capable of transmitting a wireless signal; touch key array antenna arrays and signal superposed in the same operating region, the controller controls the touch capable comprises and an alternating array of keys each array antenna signal detection operation of the timing controller. Since the touch key array antenna arrays and signal superimposed on the same operating area, greatly reduces the space occupied by the planar area of ​​the circuit board, so as to facilitate other functional member is provided; second antenna array and the array of touch keys operate alternately, they work signals between each other without forming mutual interference, but also to save power consumption.
