Abstract
Certain embodiments are directed to techniques (e.g., a method, an apparatus, and non-transitory computer readable medium storing code or instructions executable by one or more processors) for mitigating the flicker on the displays at low driving frequencies due to drops of the voltage holding ratio of the materials for the display. The techniques to compensate for flicker in a liquid crystal display can include generating a dynamic waveform for the backlight of the display. The dynamic waveform can be synchronized with the driving rate of the liquid crystal display such that the luminosity of the backlight increases during periods when the voltage-holding ratio drops in the materials of the display. In this way, a liquid crystal material can be utilized in a display to generate reduced power consumption with liquid crystal rate minimizing the flicker in response to the drops of the voltage-holding ratio.
