    Abstract: A display is provided that has upper and lower polarizers, a color filter layer, a liquid crystal layer, and a thin-film transistor layer. The color filter layer and thin-film transistor layer may be formed from materials such as glass that are subject to stress-induced birefringence. To reduce light leakage that reduces display performance, one or more birefringence compensation layers may be incorporated into the display to help compensate for any birefringence effects. The compensation layers may include a birefringence compensation layer attached to the color filter layer or the thin-film transistor layer. A display may include an upper compensation layer attached to the color filter layer and a lower compensation layer attached to the thin-film transistor layer. The compensation layer may be formed from glass or polymer materials that have a negative photo-elastic constant.

    Abstract: An active matrix liquid crystal display having an array of pixels is provided. The display includes a thin film transistor (TFT) for each pixel. The TFT has a gate electrode, a source electrode overlapping with a first area of the gate electrode, and a drain electrode overlapping with a second area with the gate electrode. The display also includes a color filter layer disposed over the TFT. The color filter layer has a first via hole to expose a portion of the drain electrode. The display further includes a metal layer disposed over the color filter layer and covering the gate electrode. The metal layer is configured to connect to the drain electrode through the first via hole. The display also includes an organic insulator layer disposed over the metal layer. The organic insulator layer has a second via hole to expose a first portion of the metal layer and a third via hole to expose a second portion of the metal layer.

    Abstract: An electronic device may be provided with a display mounted in a housing. The display may include a color filter layer, a liquid crystal layer, and a thin-film transistor layer. The color filter layer may form the outermost layer of the display. A color filter layer substrate in the color filter layer may have opposing inner and outer surfaces. A layer of patterned metal on the inner surface may form metal alignment marks. The metal alignment marks may include alignment marks for color filter elements, alignment marks for a black matrix layer that is formed on top of the color filter elements, and post spacer alignment marks. The layer of patterned metal may also form structures such as logo structures that are visible on the outer surface in an inactive border region of the display.

    Abstract: An electronic device with a display may be provided with an array of pixels each of which includes subpixels formed from organic light-emitting diodes. The electronic device may have support structures such as a head-mountable frame or other head-mountable support structure. Optical structures such as lenses may be provided through which the array of pixels is viewable by a user. The array of pixels and the lenses or other optical structures may be supported by the head-mounted support structure. Light spreading structures may overlap the array of pixels to enhance the fill factor of the pixels. The light spreading structures may be formed from a fiber bundle layer, an array of microlenses, or other optical structures that laterally spread light that has been emitted by the organic light-emitting diodes and thereby enhances the fill factor of the pixels.

    Abstract: Pixels in an organic light-emitting diode (OLED) display may be microcavity OLED pixels having optical cavities. The optical cavities may be defined by a partially transparent cathode layer and a reflective anode structure. The anode of the pixels may include both the reflective anode structure and a supplemental anode that is transparent and that is used to tune the thickness of the optical cavity for each pixel. Organic light-emitting diode layers may be formed over the pixels and may have a uniform thickness in each pixel in the display. Pixels may have a conductive spacer between a transparent anode portion and a reflective anode portion, without an intervening dielectric layer. The conductive spacer may be formed from a material such as titanium nitride that is compatible with both anode portions. The transparent anode portions may have varying thicknesses to control the thickness of the optical cavities of the pixels.
