  • Patent number: 11735127
    Abstract: A driving method for driving an electrophoretic display comprising four types of particles, the first type of particles and the third type of particles are positively charged, and the second type of particles and the fourth type of particles are negatively charged, the method comprises the steps of: (i). applying a first driving voltage to the pixel of the electrophoretic display for a first period of time at a first amplitude to drive the pixel to a color state of the fourth type of particle at the viewing side; and (ii). applying a second driving voltage to the pixel of the electrophoretic display for a second period of time, opposite to that of the first driving voltage and a second amplitude smaller than that of the first amplitude, to drive the second type particle towards the non-viewing side.

  • Patent number: 8749723
    Abstract: A driving method for a panel structure including at least two liquid crystal layers is disclosed. The liquid crystal layers display different colors. When the panel structure includes a first liquid crystal layer and a second liquid crystal layer, the first and the second liquid crystal layers are initialized. A light source is utilized to emit the first and the second liquid crystal layers to write data to at least one of the first and the second liquid crystal layers. When the panel structure further includes a third liquid crystal layer, the first, the second and the third liquid crystal layers are first initialized. A light source is utilized to emit the first, the second and the third liquid crystal layers to write data to at least one of the first, the second and the third liquid crystal layers.
