An organic electroluminescence (EL) display device assembly includes a substrate, an organic EL portion, an optical loss prevention layer, and a fine space layer. The organic EL portion has a first electrode layer, an organic luminescent layer, and a second electrode layer which are each patterned and stacked on the upper surface of the substrate. The optical loss prevention layer is used to increase light bleeding efficiency. The fine space layer is formed between the optical loss prevention layer and a layer facing the optical loss prevention layer and is filled with a gas or evacuated.

In order to obtain a satisfactory image by making a peak luminance of an image to be displayed large and suppressing an occurrence of unnecessary period, there is provided a display driving method for driving a display with a plurality of scanning wirings and a plurality of modulation wirings, comprising: a step of supplying a scan selection signal to a scanning wiring selected out of the plural scanning wirings for each horizontal scanning period; and a step of supplying a modulation signal modulated in accordance with image data to the plural modulation wirings for each horizontal scanning period, in which the selection period of the scan selection signal varies between at least two horizontal scanning periods in a vertical scanning period.

A system and method are presented for use in imaging the patient's retina. A light source unit is provided including a light emitting diode (LED) arrangement comprising multiple LEDs of different wavelength ranges. A light guide arrangement is used with the LEDs arrangement and is configured for coupling light from the LEDs and providing output light beams of a desired shape. The illuminating light is directed towards a region on the retina, and light returned from the illuminated region is collected and directed to an image detector unit. The invention enables the use of LED light at high intensity as required in the eye retina imaging, while maintaining the required high-quality imaging. Also, the invention provides for simultaneous or quasi-simultaneous as well as high-speed imaging in FA and ICG imaging procedures, thereby satisfying a long felt need in ophthalmology. Also, the invention provides for automated illumination or light exposure control to optimize overall light exposure to the patient eye and best acquired image quality in terms of brightness, contrast and image signal-to-noise ratio.

On a substrate, the pattern of the first conductive layer is defined, that is, a gate line combination including gate pads, scanning lines and gate electrodes. A gate insulating layer, a semiconductor layer, a doped semiconductor layer and a second conductive layer are deposited on the substrate and the above-mentioned gate line combination in sequence. A photoresist layer is overlaid on the second conductive layer. The photoresist layer within the aperture areas is fully exposed. Using a half-tone mask or a slit pattern to make parts of the photoresist layer lying on the gate pads and the gate electrodes are not exposed to its full depth. As a result, the photoresist pattern formed varies in thickness. After being processed with drying etching and wet etching for several times, all the layers previously deposited within the aperture areas can be totally etched and removed. However, as regards the layers deposited on the gate pads and the gate electrodes, etching only takes place in those layers above the semiconductor layer. Then, an organic protection layer is laid on the substrate and the above-mentioned structure, and the holes, which are to function as the passageways for the transparent conductive layer to contact the metallic layer, are defined on the organic protection layer. Then, the gate pads are exposed out of holes above them, using dry etching again. Lastly, the pattern of the transparent conductive layer is defined on the organic protection layer and in the plurality of holes.
