20100102706 | ELECTROLUMINESCENT DEVICE WITH INCREASED FILL FACTOR - An electroluminescent device including at least two spaced-apart electrodes wherein at least a portion of each of the two spaced-apart electrodes overlap within a first area and a second portion of the two spaced-apart electrodes do not overlap within a second area; a light-emitting layer having a first resistivity formed between the two electrodes, the light-emitting layer disposed to overlap at least a portion of both the first and second areas; a carrier-diffusing layer formed between the light-emitting layer and one of the spaced-apart electrodes; the carrier-diffusing layer disposed to overlap the light-emitting layer in at least a portion of both the first and second areas; and wherein the carrier-diffusing layer has a second resistivity selected to be lower than the first resistivity to cause light to be produced by the light-emitting layer within the first and second areas. | 04-29-2010 |
20100156271 | FLUORESCENT SCREEN AND IMAGE DISPLAY APPARATUS - An apparatus includes light emitting members; anode electrodes disposed on the light emitting members in an overlapping manner; a partition member disposed between adjacent light emitting members; a resistance member disposed on the partition member, the resistance member connecting adjacent anode electrodes to each other; and a feeding electrode connecting the resistance member to a power supply, wherein the feeding electrode is disposed on a base adjacent to the partition member, and the feeding electrode is connected, on the base, to the resistance member and to a power supply. | 06-24-2010 |
20100244661 | LATERAL FIELD EMISSION DEVICE - 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. | 09-30-2010 |
