Patent number: 11410606Abstract: A vertically stacked pixel circuit is provided that includes a high voltage device for driving a pixel on an upper silicon layer, and low voltage circuitry (such as matrix addressing circuitry, data storage circuitry and uniformity compensation circuitry) on a lower silicon layer. The circuitry on the upper and lower silicon layers are electrically connected via a through-silicon via. This unique arrangement allows the high voltage device for driving a pixel to be physically located on top of the larger number of low voltage devices in the lower silicon layer in order to achieve a substantial reduction in overall pixel emission area. The vertically stacked pixel circuit is particularly suited for organic light-emitting diode microdisplays.Type: GrantFiled: February 16, 2021Date of Patent: August 9, 2022Assignee: eMagin CorporationInventor: Ihor Wacyk

Patent number: 11149340Abstract: In a method for designing and fabricating a micro-lens array, a design is finalized by varying certain features of a shadow mask, varying a distance between a source of lens-forming material and the shadow mask, and varying other parameters until the features and distances result in the formation of a micro-lens having desired shape, etc. A shadow mask in accordance with the design is then fabricated and is appropriately positioned with respect to a micro-display and a source of lens-forming material. A plume of lens-forming material is then generated under reduced pressure and which propagates toward the shadow mask, directly patterning the micro-lenses on sub-pixels of the micro-display.Type: GrantFiled: January 26, 2018Date of Patent: October 19, 2021Assignee: eMagin CorporationInventors: Ilyas I.

Patent number: 10741129Abstract: An image rendering system comprising a pixel array and variable-density column and row scanner circuits is disclosed. The variable-density column and row scanner circuits enable software-based reconfiguration of the active display area within the available screen area of the display. In addition, a hardware restore-to-black function is provided that enables pixels outside of the desired image region to be driven to black without their requiring image data or excitation. As a result, the functionality of the functionality of the display can be reconfigured to match the desired image region on a frame-by-frame basis. Therefore, displays in accordance with the present invention can operate at higher frame rates and with less power consumption that prior-art displays.Type: GrantFiled: August 1, 2017Date of Patent: August 11, 2020Assignees: eMagin Corporation, UNITED STATES OF AMERICA, AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: Ihor Wacyk, Hyuk Sang Kwon, Russell Draper, David Fellowes

Patent number: 10297645Abstract: A full-color display panel is provided comprising a repeating super-pixel block including four pixel units, wherein each of the pixel units has a first sub-pixel configured to emit a first color light, a second sub-pixel configured to emit a second color light, and a third sub-pixel configured to emit a third color light. The first or second sub-pixel abuts the same-color sub-pixel of the adjacent pixel unit thereof to form at least a double-sized sub-pixel area. The third sub-pixel abuts the same-color sub-pixel of all adjacent pixel units thereof to form at least a quadruple-sized sub-pixel area. The first color light, the second color light, and the third color light are one of emitted through or from respective organic layers of the first color sub-pixel, the second color sub-pixel and the third color sub-pixel.Type: GrantFiled: September 6, 2017Date of Patent: May 21, 2019Assignee: eMagin CorporationInventor: Ihor Wacyk
