AI Technical Summary
Technical Problem
In the prior art, the sensor amplifier of the display panel still performs pre-charging or pre-discharging operations under the same input data, resulting in unnecessary power consumption.
Method used
The control circuit determines whether the sensing amplifier should perform pre-charge or pre-discharge operations based on the input data of the previous cycle and the current cycle. It uses a master-slave flip-flop architecture and digital logic circuits to compare data and control the operation of the sensing amplifier.
Benefits of technology
It effectively reduces unnecessary power consumption and improves the energy efficiency of the display panel.
