    摘要: Provided is a liquid crystal grating including: a first substrate; a second substrate opposite to the first substrate; a liquid crystal layer between the first substrate and the second substrate; a first electrode structure on the first substrate; and a second electrode structure on the second substrate. The first electrode structure and the second electrode structure are configured to receive control signals, the control signal including a first set of control signals and a second set of control signals; to cause the liquid crystal grating to have a first grating pitch in response to the first set of control signals; and to cause the liquid crystal grating to have a second grating pitch in response to the second set of control signals, the second grating pitch being different from the first grating pitch.

    摘要: A display panel, a fabrication method thereof and a display device are provided. The display panel has a display region (100) and a frame region (200). The display panel comprises an array substrate (01) and an opposed substrate (02) provided opposite to each other; a pattern of peripheral circuits and wires (03) is provided within the frame region (200) on a side of the array substrate (01) facing the opposed substrate (02), a pattern of a black matrix (04) is provided on the side of the array substrate (01) facing the opposed substrate (02) and/or on a side of the opposed substrate (02) facing the array substrate (01), and an orthogonal projection of the pattern of the peripheral circuits and wires (03) on the array substrate (01) does not overlap an orthogonal projection of the pattern of the black matrix (04) on the array substrate (01); and a sealant (05) which has underwent a curing treatment is provided in the frame region (200) and between the array substrate (01) and the opposed substrate (02), and the sealant (05) includes a substance formed of a thermochromic material which has changed its color in a process of the curing treatment.

    摘要: An array substrate, a driving method thereof and an electronic paper. The array substrate includes a base substrate; a plurality of gate lines and a plurality of data lines disposed on the base substrate, the plurality of gate lines and the plurality of data lines being insulated from each other and extending across each other; a gate driving circuit disposed on the base substrate and electrically connected with the gate lines; and a data driving circuit disposed on the base substrate and electrically connected with the data lines. During a display period of a frame, the gate driving circuit is configured to load gate scanning signals to respective gate lines sequentially; and while each gate line is loaded with a respective gate scanning signal, the data driving circuit is configured to transmit data signals to the data lines.
