Abstract: Devices and methods for increasing the aperture ratio and providing more precise gray level control to pixels in an active matrix organic light emitting diode (AMOLED) display are provided. By way of example, one embodiment includes disposing a gate insulator and an interlayer dielectric material between a gate electrode of a thin-film transistor of a driving circuit and a channel of the thin-film transistor. The improved structure of the driving circuit facilitates a higher voltage range for controlling the gray level of the pixels, and may increase the aperture ratio of the pixels.

Abstract: A display may be provided with integral touch functionality. The display may include a common electrode layer having row electrodes arranged in rows and column electrodes interposed between the row electrodes of each row. The row electrodes may be electrically coupled by conductive paths. The row and column electrodes may be coupled to touch sensor circuitry that uses the row and column electrodes to detect touch events. Each electrode of the common electrode layer may cover a respective portion of an array of pixels. Each pixel of the display may have a respective aperture. The conductive paths that electrically couple row electrodes of the common electrode layer may cover or otherwise block some light from passing through pixels, resulting in reduced apertures. Dummy structures may be provided for other pixels that modify the apertures of the other pixels to match the reduced apertures associated with the conductive paths.

Abstract: This application relates to methods and apparatus for refreshing a display device at various frequencies. Specifically, multiple areas of the display device can be refreshed concurrently at different frequencies. In this way, when static content is being displayed in certain areas of the display device, those certain areas can be refreshed at a lower rate than areas displaying dynamic content such as video or animation. By refreshing at lower rates, the energy consumed by the display device and subsystems associated with the display device can be reduced. Additionally, processes for reducing flicker when refreshing the display device at different refresh rates are disclosed herein.

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: An electronic device may include a display having an array of organic light-emitting diode display pixels that produce light that forms an image. Color filter elements may be used to allow the display to present color images. Each display pixel may have a red subpixel, a blue subpixel, a green subpixel, and a white subpixel. To adjust the color coordinates of the white pixel and thereby ensure that the light from the white pixel has a desired white point, part of the white subpixel may be overlapped by an area of colored color filter material. The white subpixel may, for example have a rectangular white area within which a patch of blue color filter material may be provided to make the white light from the white subpixel more bluish than it would be without the patch of blue color filter material.

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.
