ABSTRACT:
A method and a system to reduce the power consumption of a LCD driver have been achieved. In order to save power a logic circuitry is connected to the output of a RAM automatically comparing displayed data on a line by line during the scan and, on detection of no data change, keeping the output pins static. In the case a COMMON row contains zero data only the corresponding common output is not selected and does not switch the display and hence saves the charging current for said row of data. This logic circuit is an extension to standard prior art circuitry controlling a LCD display.
