    Abstract: A display may have an array of organic light-emitting diode display pixels operating at a low refresh rate. 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. One or more on-bias stress operations may be applied before threshold voltage sampling to mitigate first frame dimming. Multiple anode reset and on-bias stress operations may be inserted during vertical blanking periods to reduce flicker and maintain balance and may also be inserted between successive data refreshes to improve first frame performance. Two different emission signals controlling each pixel may be toggled together using a pulse width modulation scheme to help provide darker black levels.

    Abstract: A display may have rows and columns of pixels. Gate lines may be used to supply gate signals to rows of the pixels. Data lines may be used to supply data signals to columns of the pixels. The data lines may include alternating even and odd data lines. Data lines may be organized in pairs each of which includes one of the odd data lines and an adjacent one of the even data lines. Demultiplexer circuitry may be configured dynamically during data loading and pixel sensing operations. During data loading, data from display driver circuitry may be supplied, alternately to odd pairs of the data lines and even pairs of the data lines. During sensing, the demultiplexer circuitry may couple a pair of the even data lines to sensing circuitry in the display driver circuitry and then may couple a pair of the odd data lines to the sensing circuitry.

    Abstract: A display may have an array of pixels arranged in rows and columns. The pixels may be organic light-emitting diode pixels that each include an organic light-emitting diode and thin-film transistor circuitry for controlling the diode or may be other suitable display pixels. The pixels may form an active area of the display that displays images. Display driver circuitry may be provided in an inactive border area of the display. The display may include vertical gate lines. The display may also include data lines. The data lines may include vertical data line portions and orthogonal horizontal data line portions coupled to the vertical data line portions with vias. During operation, data from the display driver circuitry may be provided to rows of the pixels using the data lines while the vertical gate lines supply control signals to columns of the pixels.

    Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

    Abstract: A display may have rows and columns of pixels that form an active area for displaying images. A display driver integrated circuit may provide multiplexed data signals to demultiplexer circuitry in the display. The demultiplexer circuitry may demultiplex the data signals and provide the demultiplexed data signals to the pixels on data lines. Gate lines may control the loading of the data signals into the pixels. The display may have a length dimension and a width dimension that is shorter than the length dimension. The data lines may extend parallel to the width dimension and the gate lines may extend parallel to the length dimension such that there are more data lines than gate lines in the display. A notch that is free of pixels may extend into the active area. Data lines extending parallel to the width dimension of the display may be routed around the notch.
