*1 LCD module functions at the minimum frame cycle of 8.33 ms(Maximum frame frequency of
120 Hz).
Owing to the characteristics of LCD module, “shadowing” will become more eminent as frame
frequency goesup, while flicker will be reduced.
According to our experiments, frame cycle of 8.33 ms Min. or frame frequency of 120 Hz Max.
will demonstrate optimum display quality in terms of flicker and “shadowing”. But since
judgment of display quality is subjective and display quality such as “shadowing” is pattern
dependent, it is recommended that decision of frame frequency, to which power consumption of the
LCD module is proportional, be made based on your own through testing on the LCD module with
every possible patterns displayed on it.
The intervals of one LP fall and next must be always the same, and LPs must be input
continuously.
The intervals must be 70μs Max.
