Abstract:
The present invention relates to a manufacturing method and a structure of organic light-emitting diode display panels. By precisely controlling the positionnullshape and thickness of the organic light-emitting layer of pixels, the conventional cross talk problem can be solved and a better quality and longer lifetime for the OLED can be obtained. This method is to form a plurality of long grooves on a substrate, then fill the grooves with a conducting material to form a plurality of first electrode lines. A cavity matrix is formed on the first electrodes. Each individual cavity of the cavity matrix corresponds to a pixel. An organic light-emitting layer is filled in the cavities. Repeat the above steps three times, and a red-green-blue three-color organic light-emitting matrix can be obtained. A plurality of second electrode lines are formed on the organic light-emitting layer. The second electrode lines are horizontally parallel for connecting the organic light-emitting layer with the same horizontal position. Hence, a full-color organic light-emitting diode display panel can be obtained.
Abstract:
A light-emitting device (52, 80, 110, 128, or 130) suitable for a flat-panel cathode-ray tube display contains a light-emissive region (66) formed over a plate (64). The light-emissive region contains a plurality of light-emissive particles (72). Part of the outer surface of each light-emissive particle is conformally covered with one or more coatings (74, 82, 84, 112, and 114). The coatings variously provide light-reflection, gettering, intensity-enhancement, and contrast-enhancement functions.
Abstract:
A multicolored linear light source is disclosed. In an embodiment the multicolored linear light source (100) comprises a linear light source (100) emanating light of a first spectrum, and regions of photoluminescent material (102,104,106). The light of the first spectrum interacts with regions of photoluminescent material (102,104,106) to give light of a different spectrum. The composition of different regions of photoluminescent material is different, providing light of different spectra in different regions.
Abstract:
A field emission device has pixels with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light, giving the display the advantages of easy focusing, no dark spots, high brightness, and enhanced light emitting performance. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a high precision spacer to maintain a fixed distance between the cathode and the anode, enabling the device to be manufactured at reduced cost and high good yield.
Abstract:
A film for display device, a filter for display device including the film, and a display device including the filter are disclosed. The film for display device includes a plurality of first portions positioned to be spaced with a predetermined distance therebetween, and a plurality of second portions transmitting light. Each second portion is positioned between the first portions. A refractive index of the first portion is larger than a refractive index of the second portion.
Abstract:
A PDP capable of lowering a discharge initiating voltage with a weak discharge always stabilized during an initialization period even if a Xe partial pressure ratio to a total pressure in discharge gas is increased, improving an image quality with the occurrence of an initializing bright point prevented, preventing the lowering of a light emission efficiency and brightness, and improving brightness; and a production method for simply producing the PDP. The PDP comprises a front panel and a rear panel disposed facing each other with a discharge space provided between them. A fluorescent layer is formed in the area on the discharge space side of the rear panel, and a fluorescent film as a high γ portion is formed in part of the area of its surface. The fluorescent film is formed of a material higher in secondary electron emission coefficient γ than a fluorescent material constituting the fluorescent layer. Part of the surface of the fluorescent layer is covered with the fluorescent film, with the other part facing the discharge space.
