Patent ID: 8823627

Claim:
A module comprising: a display panel; and a display control device capable of adjusting a frame frequency of the display panel, the display control device comprising: an interface which receives display data from an external device to be coupled to the display module; a memory which stores the display data; a register capable of storing from the external device a division ratio, a number of a second clock signal per a scanning period, and a number of active lines of the display panel; a signal generator which divides a first clock signal by the division ratio to generate the second clock signal, and which generates a signal having the frame frequency based on the second clock signal, the number of the second clock signal per the scanning period and the number of active lines of the display panel stored in the register; a voltage generator which generates a plurality of driving voltage signals, and a data line driver which converts the display data into one of the plurality of driving voltage signals generated by the voltage generator to be provided to the display panel according to the frame frequency.
