A display system of a display includes a first light emitting diode, a second light emitting diode, a current source, and at least one transistor. The first and the second light emitting diodes emit light. The current source provides a constant current to the first light emitting diode and the second light emitting diode. Moreover, the at least one transistor removes the current or shunts the current towards the first light emitting diode, the second light emitting diode, or both. Removing the current or shunting the current towards the first light emitting diode, the second light emitting diode, or both, may blend outputs of the first light emitting diode and the second light emitting diode.

Super pixel architecture for high dynamic range

A pulse width modulation and amplitude modulation driving system for a display panel, including related circuits and methods of operation, are described. In an embodiment, a display panel includes a thin film transistor layer comprising a plurality of subpixel circuits. Each subpixel circuit may include a drive transistor, a comparator, and a switch. A plurality of light emitting diodes (LEDs), such as micro-LEDs, may be connected to the plurality of subpixel circuits. Each subpixel circuit can control an LED based on a current amplitude controlled by the drive transistor and a current pulse width controlled by the comparator and the switch. Other aspects are also described and claimed.

Emission control apparatuses and methods for a display panel

A display device may include pixels that display image data. The display device may also include a circuit that receives pixel data having a gray level for at least one pixel, such that the pixel data corresponds to a frame of the image data and the frame includes sub-frames. The pixel data causes the circuit to provide at least one current pulse to the at least one pixel according to a first order of the sub-frames. The circuit may also receive a second order of the sub-frames, such that the second order is mapped with respect to the first order, and at least one current pulse is provided to the at least one pixel according to the second order. As such, visual artifacts depicted on the display are reduced.
