※ The intervals of one LP fall and next must be always the same, and LPs must be input continuously.
*1 When LCD module is operated by high speed of XCK(Shift clock), (t
*2 LCD module functions at the minimum frame cycle of 8.33 ms(Maximum frame frequency of 120 Hz).
*3 According to our experiments, frame cycle of 8.33 ms Min. or frame frequency of 120 Hz Max. will
The intervals must be 70μs Max.
Owing to the characteristics of LCD module, “shadowing” will become more eminent as frame frequency
goes up, while flicker will be reduced.
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
