Abstract: In one embodiment, a circuit for driving an electronic component includes a first conduction path and a second conduction path connected in parallel. Each of the first and second conduction paths includes a field-effect transistor. The first field-effect transistor lies along the first conduction path, and the second field-effect transistor lies along the second conduction path. The circuit can be used in an electronic device that includes a radiation-emitting electronic component or a radiation-responsive electronic component. During a first time period, current flows through the first conduction path and the first electronic component while a second conduction path of a driving unit is off. During a second time period, current flows through the second conduction path and the first electronic component while the first conduction path of the driving unit is off.

Abstract: A display for an electronic device may be calibrated and corrected for pixel-to-pixel variations in intensity. Radiation-sensing elements used for the calibration are not incorporated as circuit elements within the pixel circuits and may lie outside the pixels. Waveguides, reflectors, or the like may be used to optically couple the radiation-emitting elements of the pixels to the radiation-sensing elements. The radiation-sensing elements may be part of an apparatus separate from the electronic device or may be embedded within the electronic device. Many different methodologies may be used for correcting intensities to achieve better homogeneity in intensity among the pixels within a display.

Abstract: Different radiation-emitting elements can be supplied different power supply potentials during operation of a display. In a display for an electronic device, a full-color pixel can include a red subpixel, a green subpixel, and a blue subpixel. The subpixels may have light-emitting diodes that comprise organic active materials with different compositions that degrade over time at different rates. By using different power supply potentials for the different subpixels, better intensity and color control can be obtained for an electronic device.
