    Abstract: An array substrate includes a base substrate and a plurality of pixel units disposed on a base substrate, and at least one pixel unit includes a plurality of thin film transistors, a first electrode, and a second electrode. The plurality of thin film transistors include at least one first thin film transistor including a first active pattern, a first gate, a first source and a first drain. The first electrode is disposed in a same layer as the first active pattern, the first electrode is coupled to the first drain, and the second electrode is disposed in a same layer as the first gate. Orthographic projections of any two in a group consisting of the first electrode, the second electrode, and the first drain on the base substrate have an overlapping region.

    Abstract: A display panel includes a first substrate and a second substrate which are arranged opposed to each other. The space between the first substrate and the second substrate is separated into a plurality of sub-pixel regions. Within each sub pixel region, a first electrode, a first fluid layer, a second fluid layer, a hydrophobic dielectric layer and a second electrode are arranged in this order. The first fluid layer is made of hydrophilic liquid. The second fluid layer is made of ink. When no electric field is applied between the first electrode and the second electrode, the ink spreads over the surface of the hydrophobic dielectric layer. When an electric field is applied between the first electrode and the second electrode, the ink aggregates to expose the hydrophobic dielectric layer.
