An image display device having such a constitution can alleviate lowering of display quality attributed to transmission delay or voltage drop of a scanning signal. | 03-04-2010 |
20100164375 | Organic electroluminescent display device and method of repairing a defective pixel of the device - The present invention provides an organic electroluminescent display device and a method of repairing a defective pixel of an organic electroluminescent display device which can realize the repairing a defective pixel to a light emitting pixel by electrically separating a leak portion which generates a defective pixel. To be more specific, a peeling suppression layer is formed between an anode and an organic light emitting layer formed on a main substrate, and a cavity is formed between the main substrate and the peeling suppression layer due to the evaporation generated by an absorption of laser beams thus electrically separating a defective portion so as to repair a black-dot defective pixel to form a light emitting pixel. | 07-01-2010 |
20100213456 | Organic Electroluminescence Display Device - An organic electroluminescence display device is disclosed wherein plural organic electroluminescence elements each having an anode, a cathode and an organic layer sandwiched in between the anode and the cathode, the plural organic electroluminescence elements including organic electroluminescence elements developing different colors in a row direction, and at least one of the organic layers having an outer edge of a conic section at an end portion in a column direction thereof, the outer edge of the conic section becoming narrower gradually in its width in a row direction of vapor deposition thereof toward an extreme end at an end portion in a column direction thereof. The organic electroluminescence display device can improve the vapor deposition accuracy and the degree of design freedom. | 08-26-2010 |
20110001767 | IMAGE DISPLAY DEVICE - An image display device includes signal lines; a video signal generating means which generates a video signal based on gray level information from the outside; a compensation signal generating means which generates a compensation signal based on the gray level information; a selecting means which alternately supplies the video signal and the compensation signal to the signal lines; and a plurality of pixel circuits which are connected to the signal lines. The compensation signal generating means generates the compensation signal based on the gray level information such that the larger the time integration of the potential of the video signal is, the smaller the time integration of the potential of the compensation signal is. | 01-06-2011 |
