Latest Patents

One of Okuda's latest patents is for an "Auto-zero applied buffer for display circuitry." This innovative system includes a pixel that emits light based on a signal provided to it. The system features a buffer circuit with a differential pair stage, a cascade stage, and an output stage. The differential pair stage receives a common mode voltage signal through a first switch, which operates in response to a specific signal. This design allows the differential pair stage to couple a capacitor to the output stage, effectively reducing offsets caused by various circuit components. The output stage then delivers the common mode voltage to the pixel when the first signal is present.

Another notable patent is for a "Digital to analog converter." This device incorporates a resistor string with multiple resistors and voltage taps. It selects a specific voltage tap based on gray level data for a pixel in a display. The device includes two amplifiers connected to either end of the resistor string, ensuring that each tap amplifier provides a reference voltage derived from the voltage between the two amplifiers.
