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:
Devices, storage media, and methods for compensating for aging and temperature variations using dual-loop compensation are provided. The compensating for temperature and aging variations of one or more pixels of the display using a coarse scan loop updated at a faster rate. Compensation also includes compensating for aging variations of the one or more pixels of the display using a fine scan loop updated at a slower rate.
Abstract:
A charge pump that can be configured to operate in a first mode and a second mode is disclosed. The charge pump can comprise a charging capacitor coupled to a first node and configured to transfer a first DC voltage to the first node. The charge pump can also comprise a first output node and a second output node coupled to the first node. During the first mode, the first output node can be configured to output a second DC voltage based on the first DC voltage, and the second output node can be configured to output a third DC voltage based on the first DC voltage. During the second mode, the first output node can be configured to output the second DC voltage, and the second output node can be configured to output an AC voltage, the AC voltage being offset by the third DC voltage.
