Abstract: A pixel element includes an emissive pixel element; and a driving circuit, coupled to the emissive pixel element, comprising: a memory circuit; a current source circuit; and a modulation circuit, coupled to the memory circuit, the current source circuit and the emissive pixel element, configured to control the current source circuit to inject a modulation current into the emissive pixel element according to modulation signals received from the memory circuit.

Abstract: A light-emitting device has power supply pads, driving pads, data pads, and pixels, all fabricated on a silicon substrate. Each pixel has power, driving, and data terminals that connect to the corresponding pads to receive power, driving, and data signals, respectively. Each pixel further includes light-emitting diodes (LEDs) and a control circuit. The control circuit, integrated within each pixel on the silicon substrate, regulates the operation of the LEDs in that pixel based on the received driving and data signals, thereby enabling individual pixel-level control within the device.
