摘要： A display has rows and columns of pixels (22). A data line (Dn) in each column provides image data signals to the pixels of that column. Each row has first and second control lines (select[m], monitor[m]) coupled to the gates of first and second respective transistors (SE, MO) in each pixel. A third transistor in each pixel servea as a drive transistor (DR) and is coupled in series with a light-emitting diode (30) between positive and ground power supply voltages (VDD, VSS). A display driver circuitry in the display characterizes each of the light-emitting diodes in a column using the data line in an adjacent column from that light-emitting diode. Each of the drive transistors in a column is characterized using the data line in that column and the data line in an adjacent column.

摘要： An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross¬ talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have a steep sidewall, a sidewall with an undercut, or a sidewall surface with a plurality of curves to disrupt continuity of the OLED layers. A control gate that is coupled to a bias voltage and covered by gate dielectric may be used to form an organic thin-film transistor that shuts the leakage current channel between adjacent anodes on the display.

摘要： An electronic device such as a head-mounted device may have displays. The display may have regions of lower (L) and higher (M, H) resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

摘要： 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.

摘要： 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.
