Abstract: A display device 18 may include a plurality of pixels 56 that display image data on a display 18, a digital-to-analog converter 84 that outputs a voltage that corresponds to a luminance value to be depicted on a first pixel 56, and a circuit 100 that amplifies the voltage and outputs an amplified voltage to the first pixel 56. The circuit 100 may include a capacitor C1 that receives the voltage via the digital-to-analog converter 84 and an amplifier 92 coupled to the capacitor C1. The amplifier 92 generates the amplified voltage based on the voltage stored the capacitor C1. The circuit 100 also include switches 102, 104, 106 that couple a first terminal of the capacitor C1 to an output of the amplifier 92 during a first amount of time and couples a second terminal of the capacitor C1 to the output of the amplifier 92 after the first amount of time expires

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: Display panel redundancy schemes and methods of operation are described. In an embodiment, and display panel includes an array of drivers (e.g. microdrivers), each of which including multiple portions to independently receive control and pixel bits. In an embodiment, each driver portion is to control a group of redundant emission elements.
