CPU frenqency change effect on LCD display

During test on the driver of LCD, we found the cpu frenquency changed depending on the algorithm which can save the power of CPU usage, but this affect on Sharp LCD flick all the time when the frenquency of cpu changes.

the solution on this we find out is a workaround method, which is: whenever the LCD is woken up, the frenquency will be set to steady, and release the setting when LCD sleeps.
