LCD refresh methodology S128240C

Dear Terry,

Thanks for your reply, as for our previous discussion regarding display refresh timing for highlighting one pixel it requires 250nsec, when we are loading the new data to LCD pixels.

Once after data is loaded (full DDRAM is filled) in the LCD and no new data is loaded in it, in that case the data what is loaded last will be hold in the ram and that data we can see on LCD, by frequent refreshing, can you please let me know how often the display refreshing is being done internally, what is the methodology for refreshing.

Actually this question is not related to software/hardware it is being done internally by the ssLCD driver ST7529, but we need to know in detail how that is being done.

Thanking you
