Abstract: Integrated touch screens are provided including drive lines formed of grouped-together circuit elements of a thin film transistor layer and sense lines formed between a color filter layer and a material layer that modifies or generates light. The common electrodes (Vcom) in the TFT layer can be grouped together during a touch sensing operation to form drive lines. Sense lines can be formed on an underside of a color filter glass, and a liquid crystal region can be disposed between the color filter glass and the TFT layer. Placing the sense lines on the underside of the color filter glass, i.e., within the display pixel cell, can provide a benefit of allowing the color filter glass to be thinned after the pixel cells have been assembled, for example.

Abstract: A display may have an array of pixels controlled by display driver circuitry. Gate driver circuitry supplies gate line signals to rows of the pixels. The gate driver circuitry may include blocks of gate driver circuits each having an output coupled to a respective one of the gate lines. The gate driver circuits of each block are coupled in a chain to form a shift register. Each block has a local block-level gate start pulse generator. The display driver circuitry has a display driver circuit that supplies a gate start pulse clock to each of the local block-level gate start pulse generators. The local block-level gate start pulse generators create gate start pulses that are applied to the first gate driver circuit in each shift register. The display driver circuit may delay the gate start pulse clock when it is desired to implement an intraframe pause.

Abstract: An electronic device may have a flexible display with portions that are bent along a bend axis. The display may have display circuitry such as an array of display pixels in an active area. Contact pads may be formed in an inactive area of the display. Signal lines may couple the display pixels to the contact pads. The signal lines may overlap the bend axis in the inactive area of the display. During fabrication, an etch stop may be formed on the display that overlaps the bend axis. The etch stop may prevent over etching of dielectric such as a buffer layer on a polymer flexible display substrate. A layer of polymer that serves as a neutral stress plane adjustment layer may be formed over the signal lines in the inactive area of the display. Upon bending, the neutral stress plane adjustment layer helps prevent stress in the signal lines.

Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The first (upper) stage may be a high resolution display panel that is operated at a first refresh rate while the second (lower) stage is a low resolution display panel that is operated at a second refresh rate that is greater than the first refresh rate. In particular, the second stage may be configured to provide localized dimming that is synchronized to one or more moving objects in the video frames to be displayed to help reduce the perceived motion blur. The localized dimming may be provided via insertion of a black image portion that only overlaps with the moving objects, a blanking row that tracks the moving objects, a black frame, etc.

Abstract: Setting a slew rate, e.g., a rising time or a falling time, of a scanning signal can be performed with a first operation, and a shunting resistance of the scanning line can be set with a second operation. A scanning system that scans a display screen, a touch screen, etc., can set a desired slew rate during a first period of time and can set a desired shunting resistance during a second period of time. A gate line system can sequentially scan gate lines to display an image during a display phase of a touch screen. The gate line system can, for example, increase the falling times of gate line signals. After the falling gate line signal has stabilized, for example, the gate line system can decrease the shunting resistance of the gate line.

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.
