A display device includes a display substrate and a backplane substrate. The display substrate includes an array of micro-LEDs forming individual pixels. The backplane substrate includes a plurality of pixel logic hardware modules. Each pixel logic hardware module includes a local memory element configured to store a multi-bit pixel intensity value of a corresponding micro-LED for an image frame. The backplane substrate is bonded to a backside of the display substrate such that the pixel logic hardware modules are physically aligned behind the array of micro-LEDs and each pixel logic hardware module is electrically connected to a micro-LED of the corresponding pixel.

Micro-LED display

A modulated light source comprises a laser diode and a drive circuit coupled operatively to the laser diode. The laser diode is configured to lase upon passing an above-threshold current for an accumulation period. The drive circuit is configured to draw a priming current through the laser diode over a priming period, the priming current being insufficient to cause the laser diode to lase during the priming period, but sufficient to shorten the accumulation period. The drive circuit is further configured to draw the above-threshold current through the laser diode after the priming period, thereby triggering emission from the laser diode following a shortened accumulation period.

Laser diode priming to reduce latency

A system for dynamically adjusting a bias voltage for a laser diode or a light emitting diode is provided. An output voltage of the laser diode is measured and a level of a supply voltage applied to the laser diode is adjusted to change the bias voltage to the laser diode to manage power usage and avoid saturation of the laser diode. Also, a junction temperature of a laser diode may be estimated by mapping a measured output voltage and known current to device characteristic data based on temperature and the supply voltage adjusted in order to bias the laser diode to compensate for a temperature change. Further, data indicating an intensity level of data to be rendered by the laser diode is used to adjust the second supply voltage to bias the laser diode in advance of rendering the data.

Dynamic supply voltage control circuit for laser diode

A system includes operational circuit blocks associated with configurable counter circuits. A configurable counter circuit is configured to control event signal when counting expires and includes a mode input configured to receive a setting of a programmable control event asynchronous mode and a programmable control event synchronous mode. Depending on the programmed mode and whether a control event has occurred in a previous synchronization period, the configurable counter circuit processes an associated operation responsive to issuance of a synchronization instruction or to issuance of a subsequent control event.

Configurable synchronized processing of multiple operations

An electronic device includes a configurable pulse generator configured to generate a programmable master pulse train. One or more functional circuits of the electronic device includes a programming interface to receive one or more a programmable slave pulse parameters for the one or more functional circuits. The programmable slave pulse parameters are dependent upon the programmable master pulse train. A slave pulse generator generates a slave pulse for one of the functional circuits based on the one or more programmable slave pulse parameters corresponding to the functional circuits relative to the programmable master pulse train.
