Abstract
Disclosed are a method, a system, and an intelligent terminal of processing the touch failure of the touch screen after it is powered on. The method includes: powering on the touch screen by a main board; reading an ID pin of the touch screen by a main control chip upon detecting a touch operation of the user clicking the touch screen; downloading software firmware by the main control chip to the chip of the touch screen through an IIC; determining, by the main control chip, whether interruption or an IIC signal of the touch screen is normal by the main control chip; if the interruption of the touch screen is normal, performing a power-on operation by the main control chip; and if the IIC signal of the touch screen is normal, performing a power-on operation by the main control chip.
