1. An electronic device, comprising:
a panel including:
a plurality of scan electrodes;
a plurality of data electrodes intersected with the plurality of scan electrodes to define a plurality of pixels; and
a cholesteric liquid crystal layer disposed between the plurality of scan electrodes and the plurality of data electrodes,
wherein, in a writing mode, a user input touches at least one pixel disposed in a writing area, and a first voltage difference is applied to the at least one pixel disposed in the writing area in response to the user input, and a second voltage difference is applied to at least a portion of the other pixels disposed in a non-writing area in response to the user input, and in an erasing mode, the user input touches at least one pixel disposed in an erasing area, and a third voltage difference is applied to the at least one pixel disposed in the erasing area in response to the user input, where the first voltage difference is different from the second voltage difference, and the first voltage difference is different from the third voltage difference,
wherein in the writing mode, the panel displays a writing according to the user input, and in the erasing mode, the panel erases at least part of the writing according to the user input;
wherein the first voltage difference is a second voltage value, the second voltage difference is a first voltage value or a data voltage, and the third voltage difference is a fourth voltage value, where Vd<V1<V2<V4, Vd stands for the data voltage, V1 stands for the first voltage, V2 stands for the second voltage, and V4 stands for the fourth voltage.
