Abstract
A display panel and control methods thereof are provided. In one example, the display panel includes, a first substrate and a second substrate opposite to each other, and a solution encapsulated between the first substrate and the second substrate. In some examples, the solution includes opaque charged particles. In some examples, the first substrate includes a first electrode, the first electrode including a plurality of discrete sub-electrodes, and the second substrate includes a second electrode. Further, the control method may include adjusting an electric field between each of the plurality of discrete sub-electrodes and the second electrode, causing the opaque charged particles to undergo a gathering motion or a scattering motion.
