Company patents

Ignis Innovation Inc.

Ignis Innovation Inc. surprisingly shows a significant decline in its core 'Display Drivers' category, which still constitutes 93.0% of its portfolio, with a -51.9% YoY drop in 2024, suggesting a potential shift away from its primary historical focus. Concurrently, the company appears to be deprioritizing several other areas, including a complete cessation of patenting in 'Organic Electronics (OLED)', 'Photometry / Spectrometry', and 'Specialty Semiconductor Devices (Legacy)' in 2024, each experiencing a -100.0% YoY decline.

PIXEL CIRCUIT, DISPLAY, AND METHOD

Filed:2023-04-20Pub:2023-08-17
Applicant:IGNIS INNOVATION INC.

A pixel circuit for an active matrix organic light emitting diode (AMOLED) and other active matrix displays is disclosed. The pixel circuit is programmed by the voltage supplied through a data line. An electrical current through a light emitting device for a known LED voltage and a pixel current for a pixel programed with a known data signal can be measured by a readout circuit through the data line. A 7T1C implementation enables to pre-charge the drive transistor to a reference voltage in each drive cycle, and to pre-set the light emitting device to a reference voltage prior to emission in each cycle.

AMOLED DISPLAYS WITH MULTIPLE READOUT CIRCUITS

Filed:2023-03-15Pub:2023-07-06
Applicant:IGNIS INNOVATION INC.

The OLED voltage of a selected pixel is extracted from the pixel produced when the pixel is programmed so that the pixel current is a function of the OLED voltage. One method for extracting the OLED voltage is to first program the pixel in a way that the current is not a function of OLED voltage, and then in a way that the current is a function of OLED voltage. During the latter stage, the programming voltage is changed so that the pixel current is the same as the pixel current when the pixel was programmed in a way that the current was not a function of OLED voltage. The difference in the two programming voltages is then used to extract the OLED voltage.
