Abstract: Disclosed embodiments provide an LED package and electronic display. An LED package can include an LED that emits red, green, blue and IR (infrared), where the IR portion is configured as either an emitter or (reversed biased) as a receiver. An electronic display includes multiple LED packages with the IR portions configured in a combination of transmitters and receivers. Thus, disclosed embodiments enable electronic displays that can serve as interactive video walls and floors that present a high-definition image along with interactive capabilities. Thus, disclosed embodiments serve to reduce cost and complexity in manufacture and deployment of such displays.

Abstract: Method, apparatuses, and systems are described to display image data to a sub- pixel within a micro-LED (mLED) display. A sub-pixel image data value is stored at the sub-pixel. The sub-pixel is turned to an ON state. A shared row counter value Is provided to the sub-pixel, The shared row counter value and the sub-pixel image data value are compared at the sub-pixel. The sub-pixel is turned to an OFF state if the shared row counter value is equal to or greater than the sub-pixel image data value.

Abstract: A display pixel may include an organic light-emitting diode, one or more emission transistors, a drive transistor, a gate setting transistor, a data loading transistor, and an initialization transistor. The drive transistor may be implemented as a semiconducting-oxide transistor to mitigate threshold voltage hysteresis to improve first frame response at high refresh rates, to reduce undesired luminance jumps at low refresh rates, and to reduce image sticking. The gate setting transistor may also be implemented as a semiconducting-oxide transistor to reduce leakage at the gate terminal of the drive transistor. The initialization transistor may also be implemented as a semiconducting-oxide transistor so that it can be controlled using a shared emission signal to reduce routing complexity. The remaining transistors in the pixel may be implemented as p-type silicon transistors. Display pixels configured in this way can support in-pixel threshold voltage compensation and on-bias stress phase to further mitigate the hysteresis.
