    摘要: Embodiments of the invention provide display substrate, method for testing the same and display apparatus. The display substrate includes pixel regions arranged in matrix and test unit, each pixel region being provided with first electrode, wherein the test unit includes at least two test sub-units; first electrodes provided in adjacent pixel regions correspond to electrode block, and electrode blocks are electrically isolated from each other and divided, in accordance with their positions, into at least two test groups whose number is the same as that of the test sub-units; the electrode blocks of a same test group are provided spaced apart from each other in both row and column directions, and all the electrode blocks in the same test group are connected to one test sub-unit. The test unit can accurately test open or short defect existing in the display substrate, thereby improving test accuracy and lowering production costs.

    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 touch display panel and a display device are disclosed. The touch display panel includes a plurality of touch signal lines and a plurality of data lines disposed in a display area, and a plurality of lead terminals disposed in a peripheral area. The plurality of lead terminals includes a plurality of first terminals respectively connected to the plurality of data lines and a plurality of second terminals respectively connected to the plurality of touch signal lines. The plurality of lead terminals are arranged in a matrix. The first terminals and the second terminals are provided in a row direction or a column direction so as to be consistent with the sequence in which the data lines connected to the first terminals and the touch signal lines connected to the second terminals are arranged.
