1. A method of processing touch failure of a touch screen at power-on of a touch screen, comprising:
powering on the touch screen is by a main board;
reading an ID pin of the touch screen by a main control chip upon detecting a touch operation of a user clicking the touch screen;
downloading software firmware by the main control chip to a chip of the touch screen through an inter-integrated circuit (IIC);
determining, by the main control chip, whether interruption of the touch screen is normal and whether an IIC signal of the touch screen is normal by the main control chip;
in response to determine that the interruption of the touch screen is normal, performing a power-on operation by the main control chip; and
in response to determine that the IIC signal of the touch screen is normal, performing the power-on operation by the main control chip.
