Latest Patents
One of his latest patents is titled "Addressing and redundancy schemes for distributed driver circuits in a display device." This invention relates to a display device that includes a control circuit, an array of light-emitting diode (LED) zones, and an array of zone integrated circuits distributed throughout the display area. The zone integrated circuits may comprise integrated LEDs, driver circuits, and at least one redundant driver circuit. In this design, a non-operational driver circuit is bypassed, allowing the neighboring driver circuit to assume the LED driving responsibility. This neighboring driver circuit may be another driver circuit or the redundant driver circuit.
Another notable patent is "Display device with selectable LED current levels based on brightness data." This invention describes a display device that comprises a control circuit and multiple LED channels coupled to a shared supply voltage. The control circuit obtains respective brightness levels for each LED channel and determines a group current level sufficient to drive all channels based on these brightness levels. It also configures driver circuits to drive the LED channels according to the group current level and respective duty cycles, ensuring optimal performance.
