  • Publication number: 20170133410
    Abstract: The present disclosure provides an array substrate and a display device that can suppress the adverse effects in display due to difference in gray-scale luminance of adjacent two rows caused by variation in capacitance of adjacent two rows of TFTs as the result of displacement of the data lines. Scan lines and data lines crossing each other are arranged on the array substrate.

  • Publication number: 20170104105
    Abstract: The present invention discloses an array substrate, a display panel and a display device. The array substrate includes a substrate, a gate line and a data line arranged on the substrate, and a thin film transistor arranged in an overlapping region where the gate line and the data line are overlapped; wherein an orthogonal projection of the thin film transistor on the substrate covers an orthogonal projection of the overlapping region of the gate line and the data line on the substrate. Because of design of a location of the thin film transistor according to the present invention, the opening ratio can be increased, the slightly rubbing region adjacent to the thin film transistor can be reduced; and, because of the closed channel region, levels at various positions of the thin film transistor can be uniform, and a bigger contact area provided for the supporting post, thereby increasing supporting ability of the supporting post and compressive property of the panel.

  • Publication number: 20150338710
    Abstract: An array structure and a method for manufacturing the same, an array substrate and a display device are provided, the array structure comprises signal input pads (3, 4) and a gate insulating layer (1), wherein the gate insulating layer (1) has grooves (P) in which the signal input pads (3, 4) are located. The grooves (P) function to accommodate the signal input pads (3, 4) for a test such as an array test and a cell test due to a position of the grooves (P) being lower than other layer structures. By means of the groove design, it is possible to decrease a difference of heights of the signal input pads and the display region, increase flatness of the display panel, further improve the uniformity of the aligning, improve the Mura defect caused by the aligning difference due to the height difference during the aligning process, and improve the product properties.
