Patent number: 10497299Abstract: A display presents information with pixels driven at overdrive voltages set based upon a user configuration and sensed environmental conditions. Varied overdrive voltages provide adaptable display responses with proportional power consumption so that power consumption is reduced where visual images of a display content have reduced need for rapid display response. For example, reduced bandwidth availability that impacts display resolution allows reduced overdrive voltages that scale to visual content resolution.Type: GrantFiled: September 13, 2017Date of Patent: December 3, 2019Assignee: Dell Products L.P.Inventors: Stefan Peana, Chung-Jen Chen, Kenneth W.

Patent number: 10049614Abstract: An OLED degradation compensation system includes a display system having an OLED display device. A computing device is coupled to the display system and includes an OLED display device adjustment database storing an OLED table that is associated with a usage time of the OLED display device and that includes OLED compensation information that is based upon the usage time. An OLED display device use tracking engine in the computing system determines usage data for the OLED display device. An OLED display device adjustment engine in the computing system retrieves the usage data determined by the OLED display device use tracking engine, uses the usage data to select the OLED table in response to the usage data corresponding to the usage time associated with the OLED table, and causes at least one OLED in the OLED display device to be powered using the OLED compensation information in the OLED table.Type: GrantFiled: October 28, 2015Date of Patent: August 14, 2018Assignee: Dell Products L.P.Inventors: Stefan Peana, Jace Files, Kenneth W.
