Note)
1. In this documentation, all reliabilities are specified for timing specification based on refresh rate of 60Hz.
However, LP140WD1 has a good actual performance even at lower refresh rate( eg. 40Hz or 50Hz) for
power saving mode, whereas LP140WD1 is secured only for function under lower refresh rate.
60Hz at Normal mode, 50Hz ,40 Hz at Power save mode. Don’t care Flicker level (power save mode).
