  • Patent number: 10803775
    Abstract: A display apparatus according to one embodiment comprises pixels each comprising a liquid crystal display element (LC element) and an organic EL display element (EL element). The EL element comprises an anode and a cathode electrically separated from each electrode of the LC element. Each pixel comprises a first transistor which changes the magnitude of a current flowing through the EL element based on the potential of a first bus line; a second transistor which electrically separates the first bus line and the LC element; and a third transistor which electrically connects the first and second transistor with the first bus line. A method for driving a display device according to one embodiment reduces the potential difference between the pixel electrode and the counter electrode before turning off the second transistor during switching from display by the LC element to display by the EL element.

  • Patent number: 10126237
    Abstract: An inspection apparatus comprises an illumination system (12) for illuminating a target structure with illuminating radiation and a collection system for collecting the illuminating radiation after it has been scattered by the target structure. A programmable spatial light modulator (713) comprises an array of movable mirror elements (742) in a conjugate pupil plane (P?) of the illumination system. Between the array of mirror elements and the target a common optical path is defined forming part of the illumination system and the collection system. Each mirror element is movable between a first position where it reflects illuminating radiation into the common optical path and a second position where it reflects radiation from the common optical path toward a detector (19, 23). Various combinations of illumination aperture and collection aperture can be defined without the light losses associated with beam splitters and transmissive spatial light modulators.

  • Patent number: 10095099
    Abstract: A display screen includes a filter layer, a fluorescent layer having parallel fluorescent stripes, and an attachment layer between an excitation side of the fluorescent layer and a first side of the filter layer to attach the excitation side of fluorescent layer to the filter layer while providing vertical separation therebetween. The attachment layer includes attachment regions that are separated from each other by lateral spacings such that excitation-side air gaps are formed between areas of the fluorescent layer and the filter layer that correspond to the lateral spacings. During display operation, excitation light received on a second side of the filter layer propagates through to the first side of the filter layer, and at least a portion of the excitation light that propagates from the second side of the filter layer travels through the excitation-side air gaps to excite the fluorescent stripes.

  • Patent number: 9953591
    Abstract: Systems, apparatuses, and methods for driving a split display with multiple display pipelines. Frames for driving a display are logically divided into portions, a first display pipeline drives a first portion of the display, and a second display pipeline drives a second portion of the display. Each display pipeline generates dither noise for each frame in its entirety but only utilizes dither noise for the portion of the frame which is being driven to its respective portion of the display. This approach prevents visual artifacts from appearing at the dividing line between the first and second portions of the display.
