ABSTRACT:
A method for preventing direct current shock to a liquid crystal display module. In the method, a driving signal of a liquid crystal display, generated by processing signals input from a host via an interface, is enabled only after the lapse of a time period beginning when a voltage is first supplied to the liquid crystal display module from a power source. Accordingly, DC shock to the LCD module is precisely prevented.
