    Abstract: A thin-film transistor having a protection layer for a planarization layer. The protection layer prevents reduction of the planarization layer during an ashing process, thereby preventing the formation of a steeply tapered via hole through the planarization layer. In this manner, the via hole may be coated with a conductive element that may serve as a conductive path between a common electrode and the drain of the transistor.

    Abstract: An electronic display for providing a visual or video output for an electronic device. The electronic device includes a transistor layer configured to activate a first pixel row and a second pixel row. For each pixel in the first pixel row and the second pixel row, the transistor layer includes a switch transistor, a pixel electrode, and a common electrode. The electronic device further includes a pixel controller for selectively activating each pixel. The pixel controller includes a first gate line, a first drive line, and a second drive line. During operation, the first gate line provides a charge to the pixel electrode for a first pixel in the first pixel row and for a second pixel in the second pixel row, and the first drive line activates the switch transistor for the first pixel, and the second drive line activates the switch transistor for the second pixel.

    Abstract: An electronic device may have a housing and a display in the housing. The display may have one or more curved edges such as curved edges associated with rounded corners in the display and housing. The display may have an array of pixels. The display may include full-strength pixels and may have a band of antialiasing pixels having selectively reduced strengths to visually smooth content displayed along the curved edges. The pixels may be organic light-emitting diode pixels, liquid crystal display pixels, or other display pixels. Organic light-emitting diode pixels may have drive transistors and associated organic light-emitting diodes. Selectively elevated series or opaque light blocking structures of selectively reduced areas may be used to selectively reduce the strength of the antialiasing pixels. Liquid crystal display pixels may include electrodes of different shapes and/or opaque layer openings of different sizes to form antialiasing pixels in desired patterns.

    Abstract: A display is provided that includes an array of display pixels and gate driver circuitry for providing data and gate line signals to the display pixels. Gate driver circuitry may include gate driver circuits that generate the gate line signals. A gate driver circuit may include at least a buffer transistor, a bootstrapping capacitor coupled to the buffer transistor, a pulldown transistor coupled in series with the buffer transistor, and an isolation transistor coupled to the gate of the pulldown transistor. The buffer transistor may directly receive a first clock signal, whereas the isolation transistor may directly receive a second clock signal that is complementary to the first clock signal. The pulldown transistor is substantially larger than the buffer transistor. The buffer transistor is substantially larger than the isolation transistor. Configured as such, clock loading is minimized while the pulldown transistor is sized to provide the desired fall time performance.

    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: A display may have upper and lower display layers. A layer of liquid crystal material may be interposed between the upper and lower display layers. The display layers may have substrates. The display layers may include a color filter layer having an array of color filter elements on a glass substrate and a thin-film transistor layer having a layer of thin-film transistor circuitry on a glass substrate. Dielectric layers within the display layers such as dielectric layers within the thin-film transistor layer may have differing indices of refraction. Reflections and color shifts due to index of refraction discontinuities may be minimized by interposing graded index dielectric layers between adjacent layers with different indices. The graded index layers may be formed from structures with a continuously varying index of refraction or structures with a step-wise varying index of refraction.
