An EL element (60) comprises an anode (61), a cathode (67), and an emissive element layer (66) interposed between the two electrodes. A TFT is connected to the anode (61) at its source electrode (33s). The peripheral portion of the anode (61) and the entire region over the TFT are covered with a planarizing insulating film (17), and a part of the exposed portion of the anode (61) is connected to the emissive element layer (66). According to the above arrangement, it is possible to prevent disconnection of the emissive element layer (66) which may be caused by an uneven surface created by the thickness of the anode (61), and to avoid formation of a short circuit between the anode (61) and the cathode (67).

Field sequential light source modulation for a digital display system
ActiveUS20070035707A1Improve display qualityHigh resolutionTelevision system detailsStatic indicating devicesData streamImaging processing
A digital display system consists of an image modulator and multiple light modulators. An image processing system processes an incoming data stream, scans processed data to an image modulator and controls for the light modulators. Other user inputs and sensors are used to affect the processing and controls. The timing for scanning the processed data into the image modulators is controlled along with the intensity and wavelength of the light modulators. The display system may implement a spatial and temporal image processing, digital shutter controls, rolling shutter controls, sequential color output, adaptive dynamic sensor feedback, frame rate matching, motion compensated field sequencing and a variety of other techniques to produce a high quality display output. The resulting display has improved image consistency, enhanced color gamut, higher dynamic range and is better able to portray high motion content.

Image and light source modulation for a digital display system
ActiveUS20070035706A1Improve display qualityImprove consistencyTelevision system detailsProjectorsDisplay deviceSystem configuration
Image processing enhances display quality by controlling both the image modulator and the light sources to produce the best possible visual images. The image processing system utilizes a combination of user inputs, system configuration, design information, sensor feedback, pixel modulation information, and lighting control information to characterize the display environment on a per pixel basis. This per pixel characterization information is combined with one or more frames of the incoming real time display data. The image processing system processes each incoming pixel and produces a modified corresponding output pixel. Each pixel of each frame is processed accordingly. In addition to producing modified output pixels, the image processing system produces control information for the light sources. The light source control information can control individual lamps, tubes or LEDs, or can control a block or subset of the light sources. The resulting display has improved image consistency, enhanced color gamut, higher dynamic range and is better able to portray high motion content.
