    摘要: A display may have an array of organic light-emitting diode display pixels. Each display pixel may have a light-emitting diode that emits light under control of a drive transistor. Each display pixel may also have control transistors for compensation and programming operations. Each display pixel may have six thin-film transistors and one capacitor. One of the six transistors may serve as the drive transistor and may be compensated using the remaining five transistors and the capacitor. The capacitor may have a first terminal coupled to the gate of the drive transistor and a second terminal coupled to the light-emitting diode. In one embodiment, two scan control signals and two emission control signals may be used for each row of display pixels. In another embodiment, a single scan control signal and a single emission control signal may be formed for each row of display pixels.

    摘要: A liquid crystal display may have a layer of liquid crystal material. The display may have an array of display pixel circuits. The display pixel circuits may each include a display pixel electrode that applies electric fields to a corresponding portion of the liquid crystal material. Thin-film transistor circuitry and other structures in the display pixels may control operation of the display pixels circuits. The thin-film transistor circuitry may be configured to handle operation of the display at multiple refresh rates. To accommodate multiple refresh rates, each pixel circuit may include a pair of transistors. A first transistor is used to apply data signals from a data line to the display pixel electrode. A storage capacitor is used to maintain the data signal on the electrode. The second transistor may be used to adjust the capacitance of the storage capacitor depending on the refresh rate of the display.

    摘要: A liquid crystal display having an outer layer such as a thin-film transistor layer and an inner layer such as a color filter layer may be mounted in a metal device housing. Transparent conductive coating material may be formed on display layers. The transparent conductive coating material may include a layer on the upper surface of the thin-film transistor layer, a layer on the lower surface of the color filter layer, and an edge coating that extends between the upper surface layer and lower surface layer. Electrostatic discharge protection structures for the display may include a conductive elastomeric gasket that couples the upper surface layer to an inner surface of the housing, a conductive tape that couples the lower surface layer to the inner surface, and a conductive material on the inner surface that contacts the edge coating.

    摘要: A liquid crystal display may have a thin-film transistor layer with an array of pixel electrode structures for applying electric fields to a liquid crystal layer. The liquid crystal display may also have a color filter layer with an array of color filter elements. The color filter elements may allow the display to display color images. The color filter layer may be interposed between the thin-film transistor layer and a backlight. The liquid crystal layer may be sandwiched between the thin-film transistor layer and the color filter layer. The color filter layer may have a transparent substrate on which the color filter elements are formed. Black masking structures may be formed on a transparent overcoat layer that covers the color filter elements. Black column spacers may be formed from the same layer of material that forms the black masking structures.

    摘要: An electronic device may be provided with a display that has a layer of liquid crystal material interposed between a color filter layer and a thin-film-transistor layer. The thin-film-transistor layer may have a substrate with an upper surface and a lower surface. A circular polarizer may be formed on the upper surface. Thin-film transistor circuitry such as gate driver circuitry may be formed on the lower surface. A display driver circuit may be mounted on an inactive border region of the lower surface of the thin-film transistor substrate. Display pixels may form an array in a central active region of the display. A grid of metal gate and data lines may distribute signals from the display driver circuit and gate driver circuitry to the display pixels. A grid of non-reflecting lines may be interposed between the grid of metal lines and the lower surface.
