Abstract: A system and device for driving high resolution monitors while reducing artifacts thereon. Utilization of Z-inversion polarity driving techniques to drive pixels in a display reduces power consumption of the display but tends to generate visible horizontal line artifacts caused by capacitances present between the pixels and data lines of the display. By introducing a physical shield between the pixel and data line elements, capacitance therebetween can be reduced, thus eliminating the cause of the horizontal line artifacts. The shield may be a common voltage line (Vcom) of the display.

Abstract: A display may have an array of pixels arranged in rows and columns. Each pixel may have a transistor for controlling the amount of output light associated with that pixel. The transistors may be thin-film transistors having active areas, first and second source-drain terminals, and gates. Gate lines may be used to distribute gate control signals to the gates of the transistors in each row. Data lines that run perpendicular to the gate lines may be used to distribute image data along columns of pixels. The gate lines may be connected to gate line extensions that run parallel to the data lines. The data lines may each overlap a respective one of the gate line extensions. Vias may be used to connect the gate line extensions to the gate lines. The gate line extensions may all have the same length.

Abstract: A touch screen display may include gate line driver circuitry coupled to a display pixel array. The display may be provided with intra-frame pausing (IFP) capabilities, where touch or other operations may be performed during one or more intra-frame blanking intervals. In one suitable arrangement, a gate driver circuit may include multiple gate line driver segments each of which is activated by a separate gate start pulse. Each gate start pulse may only be released at the end of an IFP interval. In another suitable arrangement, dummy gate driver units may be interposed among active gate driver units. Gate output signals may propagate through the dummy gate driver units during the IFP internal. In another suitable arrangement, each active gate driver unit may be provided with a buffer portion that protects at least some transistor in the gate driver unit from undesired stress.

Abstract: A method is provided for fabricating a thin-film transistor (TFT). The method includes forming a semiconductor layer over a gate insulator that covers a gate electrode, and depositing an insulator layer over the semiconductor layer, as well as etching the insulator layer to form a patterned etch-stop without losing the gate insulator. The method also includes forming a source electrode and a drain electrode over the semiconductor layer and the patterned etch-stop. The method further includes removing a portion of the semiconductor layer beyond the source electrode and the drain electrode such that a remaining portion of the semiconductor layer covers the gate insulator in a first overlapping area of the source electrode and the gate electrode and a second overlapping area of the drain electrode and gate electrode.

Abstract: A display may have a color filter layer and a thin-film transistor layer. A layer of liquid crystal material may be located between the color filter layer and the thin-film transistor layer. Column spacers may be formed on the color filter layer to maintain a desired gap between the color filter and thin-film transistor layers. Support pads may be used to support the column spacers. Different column spacers may be located at different portions of the support pads to allow the support pad size to be reduced while ensuring adequate support. Lateral movement blocking structures such as circular rings may be used to prevent column spacer lateral movement. Subspacers located over pads may be used to create friction that retards lateral movement. Lateral movement may also be retarded by receiving column spacers in trenches or other recesses formed on a thin-film transistor layer.
