    Abstract: An electronic device display may have an array of pixel circuits. Each pixel circuit may include an organic light-emitting diode and a drive transistor. Each drive transistor may be adjusted to control how much current flows through the organic light-emitting diode. Each pixel circuit may include one or more additional transistors such as switching transistors and a storage capacitor. Semiconducting oxide transistors and silicon transistors may be used in forming the transistors of the pixel circuits. The storage capacitors and the transistors may be formed using metal layers, semiconductor structures, and dielectric layers. Some of the layers may be removed along the edge of the display to facilitate bending. The dielectric layers may have a stepped profile that allows data lines in the array to be stepped down towards the surface of the substrate as the data lines extend into an inactive edge region.

    Abstract: Systems and electronic displays with improved contrast even under bright-light conditions are provided. Such an electronic display may include a self-emissive pixel (e.g., OLED or μ-LED) with a corresponding liquid crystal switchable retarder pixel. A liquid crystal layer of the switchable retarder pixel may be tuned to an “on” state or an “off” state. In the “on” state, the switchable retarder pixel may allow outside light that enters the pixel to reflect back out of the pixel. This may add to the amount of light that appears to be emitted from that pixel. In the “off” state, the switchable retarder pixel may block the outside light that enters the pixel from reflecting back out of the pixel. This may reduce the amount of light that appears to be emitted from that pixel. Selectively controlling the switchable retarder pixels may allow for increased contrast even under bright-light conditions.

    Abstract: An organic light-emitting diode display may have an array of pixels. Each pixel may have an organic light-emitting diode with an anode and cathode. The anodes may be formed from a patterned layer of metal. Thin-film transistor circuitry in the pixels may include transistors such as drive transistors and switching transistors. Data lines may supply data signals to the pixels and horizontal control lines may supply control signals to the gates of the transistors. A switching transistor may be coupled between a voltage initialization line and each anode. The voltage initialization lines and capacitor structures in the thin-film transistor circuitry may be formed using a layer of metal that is different than the layer of metal that forms the anodes.

    Abstract: This application sets forth a circuit configuration for a light emitting diode (LED) or organic light emitting diode (OLED) display. The circuit configuration allows for the pulse-width modulation (PWM) of each emission signal sent to each line of the display. The PWM of each emission signal is accomplished using a gate-in-panel (GIP) controller of the display. The GIP controller uses an arrangement of shift register outputs and a programmable clock input to control an output of an inverter that provides the emission signal. The programmable clock input can be programmed according to a desired timing or duty cycle for the emission signal. In this way, by limiting the duty cycle of the emission signal, dimming and other display features can be exhibited by the LED or OLED display.

The light-emitting diodes may be inorganic light-emitting diodes formed from separate crystalline semiconductor structures. An array of pixel control circuits may be used to control light emission from the light-emitting diodes. Each pixel control circuit may be used to supply drive signals to a respective set of the light-emitting diodes.

    Abstract: 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 compensating and programming operations. The array of display pixels may have rows and columns. Row lines may be used to apply row control signals to rows of the display pixels. Column lines (data lines) may be used to apply display data and other signals to respective columns of display pixels. Display driver circuitry may simultaneously compensate multiple rows of the display pixels for drive transistor threshold voltage variations by supplying a common reference voltage over the data lines during a common compensation period. The display data may then be loaded into the rows sequentially before simultaneously commencing emission in each of the compensated and programmed rows.
