  • Publication number: 20150243689
    Abstract: The present disclosure relates to a thin film transistor substrate having two different types of thin film transistors on the same substrate, and a display using the same. A display includes a first thin film transistor including a poly crystalline semiconductor layer, a first gate electrode on the poly crystalline semiconductor layer, a first source electrode, and a first drain electrode; a second thin film transistor including a second gate electrode, an oxide semiconductor layer on the second gate electrode, a second source electrode, and a second drain electrode; and an intermediate insulating layer including a nitride layer and an oxide layer on the nitride layer, the intermediate insulating layer disposed on the first gate electrode and the second gate electrode and under the oxide semiconductor layer.

  • Publication number: 20150187851
    Abstract: An organic light-emitting diode display can include an improved aperture ratio by configuring a circuit pattern between neighboring subpixels in a symmetrical fashion such that the subpixels share signal lines. Each pixel of the organic light-emitting diode display is formed in a symmetrical fashion with respect to one contact area, the number of reference connecting patterns can be reduced and therefore the area occupied by an opening area for each pixel can be made wider, thus leading to an improved aperture ratio.

  • Publication number: 20150187810
    Abstract: A display device including a first substrate. The first substrate including an active region and a dummy region formed in an outer edge of the active region, the active region including a plurality of pixel regions and being configured to implement an actual image, the dummy region including a gate in panel (GIP) circuit, control signal lines, a ground, and common lines. The GIP circuit is overlapped by at least a part of the control signal lines, the ground, and the common lines with an insulating layer interposed therebetween. The display device further includes a thin film transistor (TFT) for a shift register is provided in each of a plurality of stages of the GIP circuit; and a source contact hole and a gate contact hole of each TFT for the shift registers, the source contact hole and the gate contact hole being formed along a corresponding control signal line.

  • Publication number: 20150161956
    Abstract: A liquid crystal display device includes a display panel including gate lines and data lines, the gate lines and the data lines intersecting, and pixels defined at the intersections of the gate lines and data lines, a gate driver to sequentially output a gate driving signal to the gate lines, a data driver to sequentially output a data signal to channels, a switching controller to electrically connect one of the channels with two or more of the data lines, the switching controller including a switch for each of the channels, wherein the two or more data lines are adjacent, one is directly connected to the channel and the other is connected to the channel through the switch, and a timing controller to provide a selection signal to the switch which controls the connection between the other of the two or more data lines and the channel.
