Abstract
Embodiments of the present disclosure provide a display panel and a driving method thereof. The display panel includes a first substrate and a second substrate which are aligned and assembled into a cell, wherein the first substrate includes a first base body, a total internal reflection structure and a first electrode are provided at a side of the first base body facing to the second substrate, and the second substrate includes a second base body and a second electrode which is provided at a side of the second base body facing to the first substrate. The display panel further includes cholesteric liquid crystal provided between the first and second substrates, charged light-absorbing particles are mixed in the cholesteric liquid crystal, and a refractive index of the cholesteric liquid crystal is smaller than each of refractive indexes of the total internal reflection structure and the light-absorbing particles.
