Patents by Inventor Lech Michalski

Lech Michalski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10839734
    Abstract: Techniques, devices, and systems are provided that allow for driving a device such as an OLED in various pulsed modes in which a momentary luminance greater than an apparent luminance at which the OLED is to be driven is used. The use of one or more pulsed modes allows for the lifetime of the OLED to be extended and reduces image sticking. Pulsed modes are also provided that allow for color tuning of the device by activating different portions of one or more emissive areas of the device.
    Type: Grant

  • Patent number: 8664970
    Abstract: A method for accelerated life testing of organic devices is provided. The lifetime of each of one or more individual organic emissive devices is measured at a non-heating current density. Based upon the measured lifetimes of the one or more devices, the device lifetime is determined for a selected luminance. An organic emissive panel is also obtained having a second organic stack that consists essentially of the one or more organic layers of the first organic stack. The junction temperature of the organic emissive panel is then determined at a heating current density. Based upon the junction temperature and the device lifetime of the one or more individual organic emissive devices, the expected lifetime of the organic emissive panel is then determined at the heating current density.

  • Publication number: 20120235701
    Abstract: A method for accelerated life testing of organic devices, and in particular large area organic emissive devices, is provided. The first method comprises obtaining one or more individual organic emissive devices, each having a first organic stack comprising one or more organic layers. The lifetime of each of the one or more individual organic emissive devices is measured at one or more temperatures at a non-heating current density. Based upon the measured lifetimes at the non-heating current density of the one or more devices, the device lifetime is determined for a selected luminance. An organic emissive panel is also obtained having a second organic stack that consists essentially of the one or more organic layers of the first organic stack. The junction temperature of the organic emissive panel is then determined at a heating current density.

  • Patent number: 6055089
    Abstract: A sealed insulated glass unit is provided with an electrochromic device for modulating light passing through the unit. The electrochromic device is controlled from outside the unit by a remote control electrically unconnected to the device. Circuitry within the unit may be magnetically controlled from outside. The electrochromic device is powered by a photovoltaic cells. The photovoltaic cells may be positioned so that at least a part of the light incident on the cell passes through the electrochromic device, providing a form of feedback control. A variable resistance placed in parallel with the electrochromic element is used to control the response of the electrochromic element to changes in output of the photovoltaic cell.
