Booster Efficiency
By Booster Stages (3X, 4X, 5X, 6X) and Booster Efficiency (Level1~2) commands, we could easily set the best Booster
performance with suitable current consumption. If the Booster Efficiency is set to higher level (level2 is higher than level1),
The Boost Efficiency is better than lower level, and it just need few more power consumption current. It could be applied to
each multiple voltage Condition.
When the LCD Panel loading is heavier, then the Performance of Booster will be not in a good working condition. We could
set the BE level to be higher. We do not need to change to higher Booster Stage, and just need few more current.
The Booster Efficiency Command could be used together with Booster Stage Command to choose one best Boost output
condition. We could see the Boost Stage Command as a large scale operation, and see the Booster Efficiency Command
as a small scale operation. These commands are very convenient for using.
