Jan Bernkopf 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: 7911130
    Abstract: Evaporated receptacles for inkjet deposited polymeric light-emitting diode (PLED)/organic light-emitting diode (OLED) and a method of making the same. The evaporated receptacles are formed via a shadow mask vacuum deposition process. The method of forming a light-emitting display includes forming an electrode on a substrate, forming a receptacle structure over the electrode via a shadow mask vacuum deposition process, and delivering a quantity of polymeric solution, which contains a light-emitting material, into the receptacle via a standard inkjet deposition process.
    Type: Grant

  • Patent number: 7535171
    Abstract: A system and method for improving light extraction from luminescent devices such as light-emitting flat-panel displays (for example, light-emitting diode (OLED) flat-panel displays) or flat panel lamps. The system includes a material with negative index of refraction, preferably with n=?1. The presence of such material on the exit surface of the electro-optic devices such as flat panel display or lamp with light-generating medium sandwiched between materials with refractive index n>1 fully removes TIR and results in light outcoupling efficiency of about 100%.

  • Patent number: 6844673
    Abstract: Methods and apparatuses for fabricating an electroluminescent display structure. A method including coupling a frontplane to a backplane wherein a frontplane top surface laminates to a backplane top surface. The frontplane and the backplane are fabricated separately. A first electrode layer which is transparent is disposed over the frontplane. A display medium which produces electro-optical effects upon a voltage application is disposed over the first electrode. A second electrode layer which is pattered is disposed over the display medium. The second electrode layer includes a plurality of connecting regions. The backplane is electrically active to provide driving signals for the display medium wherein the backplane includes a plurality of output pads to match the plurality of connecting regions.

  • Patent number: 5353133
    Abstract: A flat-panel display system and a display method utilizing microprojection techniques whereby each pixel of the display acts as its own micro-projector. The micro-projector utilizes a reversed Schlieren optical arrangement. A flat fiber-optic illuminator and an illumination method provide collimated light for the display. A layer of light scattering material such as polymer dispersed liquid crystal (PDLC) is interposed between the illuminator and the rear-projection screen of the display. The scattering layer, when in a first state, allows the collimated light to pass through openings in an aperture plate that is part of the microprojection display. In a second state, the scattering layer scatters the collimated light. Side and vertical walls of the aperture plate absorb most of the scattered light resulting in a high contrast ratio for the display. The degree of scattering can be controlled to provide for a gray scale for the display.
