Electronic device having at least one cholesteric liquid crystal layer

An electronic device, comprising:

• a first panel, including:
• a plurality of first electrodes;
• a plurality of second electrodes intersecting with the plurality of first electrodes to define a plurality of pixels;
• and
• a cholesteric liquid crystal layer disposed between the plurality of first electrodes and the plurality of second electrodes,
• wherein the plurality of pixels operate through a plurality of phases,
• wherein at least one of the plurality of phases is a low wave phase,
• wherein, when one of the plurality of pixels operates in the low wave phase at a first temperature, a first voltage waveform is applied to one of the plurality of first electrodes and a second voltage waveform is applied to one of the plurality of second electrodes, so that the cholesteric liquid crystal layer corresponding to the one of the plurality of pixels receives a first voltage difference, and the first voltage difference is not equal to zero, and
• wherein, when the one of the plurality of pixels operates in the low wave phase at a second temperature different from the first temperature, the cholesteric liquid crystal layer corresponding to the one of the plurality of pixels receives a second voltage difference to present substantially same brightness as presented at the first temperature, and the first voltage difference is different from the second voltage difference.
