Abstract:
1. A liquid crystal display control circuit comprising: a counter, inputted with a display control signal for controlling a display status of a display unit and a display clock signal corresponding to an image data to be displayed on the display unit, for counting a number of clock pulses of the display clock signal in 1 cycle of the display control signal and for outputting the number of clock pulses of the display clock signal in 1 cycle of the display control signal as a first count value, and for counting a number of clock pulses during a cycle of the display control signal as a second count value; a reference count value circuit inputted with the first count value, for calculating a reference count value based on the first count value; and a comparator for generating a driver control signal that changes a current capacity of the driver unit, wherein the driver control signal has a first value when the reference count value is greater than the second count value and the driver control signal has a second value when the reference count value is less than the second count value.
