摘要： A photo sensor is disposed on the same substrate as that of a display area. External light sensed by the photo sensor is inputted into a luminance adjustment controller, and luminance necessary to maintain constant contrast is obtained. A correction value corresponding to the luminance to be adjusted is outputted as a white reference voltage or a value of a CV power source to be fed back to the display area. Constant contrast of the display area can be maintained even when surrounding light intensity varies. Moreover, an amount of electric current is adjusted according to the ambient light, leading to reduction in power consumption and extension of operating life.

摘要： The invention is directed to repairing of a defective portion caused by a short circuit without generating a dark spot by a pin hole. Laser beams are irradiated to an irradiating region set in a peripheral region of a foreign substance. This prevents damaging of an organic EL element which the foreign substance adheres to and formation of the pin hole. By irradiating laser beams to the peripheral region at a distance from the foreign substance, energy of the laser beams spreads concentrically around the irradiating region, and is also supplied to the foreign substance indirectly. Therefore, the high resistive region can be formed between an anode layer and a cathode layer so that the defective portion caused by the short circuit by the foreign substance can be repaired.

摘要： Since a photosensor using a diode is incapable of perform refresh because of the structure, and the leak characteristics are unstable, the diode is not suitable for the photosensor. On the other hand, in a photosensor using a thin film transistor, since light quantity is very small, there has been a problem that feedback is difficult. A detection circuit converting an output current into a voltage is added to a photosensor using a thin film transistor. Thus, it is possible to convert a very small current into a voltage in a desired range enabling feedback. In addition, by varying resistors, capacitors, and the number of TFTs connected in the photosensor included in the circuit, it is made possible to change the sensitivity of the photosensor.
摘要翻译：由于使用二极管的光电传感器由于结构不能进行刷新，并且泄漏特性不稳定，所以二极管不适用于光电传感器。另一方面，在使用薄膜晶体管的光电传感器中，由于光量非常小，所以存在反馈困难的问题。使用薄膜晶体管将输出电流转换为电压的检测电路加到光传感器上。因此，可以将非常小的电流转换成能够进行反馈的期望范围内的电压。此外，通过改变电阻器，电容器以及连接在包括在电路中的光电传感器中的TFT的数量，可以改变光电传感器的灵敏度。

摘要： Conventionally, in the case where optical sensors are included in a display device, separate modules manufactured in separate steps are included in the same casing. However, reduction in the number of parts and in costs cannot be achieved, and reduction in size and thickness of the display device has not been realized. An optical sensor is realized by use of a TFT provided on an insulating substrate. The TFT is used as the optical sensor by detecting a photocurrent generated by incident ambient light when the TFT is off. By increasing a gate width W of the TFT, a region where the photocurrent is generated is increased, and the optical sensor with good sensitivity is realized. Moreover, since the optical sensor can be realized by use of a TFT provided on a glass substrate, the optical sensor can be provided on the same substrate as that of an EL display device.

摘要： A computer-readable storage medium having stored therein an information processing program to be executed by a computer is provided. The information processing program causes the computer to function as: preferential display object placing means for placing a preferential display object in an imaging range of a virtual stereo camera in a virtual three-dimensional space; stereoscopically visible image rendering means for taking the virtual three-dimensional space using the virtual stereo camera, and rendering a stereoscopically visible image of the virtual three-dimensional space; and display control means for causing the display apparatus to display the stereoscopically visible image rendered by the stereoscopically visible image rendering means. The stereoscopically visible image rendering means renders the preferential display object by using a parallax based on a first depth from the virtual stereo camera, according to a preference order based on a second depth, shallower than the first depth, from the virtual stereo camera.

摘要： Disclosed is a light-emitting display having a plurality of pixels wherein each pixel comprises a light-emitting device (100) having a light-emitting element layer which is formed between a first electrode and a second electrode and contains at least a light-emitting layer. An insulating layer (30) is formed between the light-emitting device (100) and a surface of a first or second substrate on the viewing side of the display, and the insulating layer (30) is provided with recesses and projections in at least one or more pixel regions, thereby forming an optical path length adjusting portion (32). By forming such an optical path length adjusting portion (32) in a pixel region, there is an increase in the interference conditions for the light emitted from the light-emitting device (100) to the outside, thereby averaging the interference.

摘要： A concave and convex portion is formed on the surface of the planarization insulating film. The surface of the anode also has a concave and convex portion, reflecting the concave and convex structure of the planarization insulating film. The hole transportation layer, the emissive layer, the electron transportation layer and the cathode are disposed on the anode through vacuum evaporation. The surface of the hole transportation layer, the emissive layer, the electron transportation layer, and the cathode has the concave and convex structure, respectively, reflecting the concave and convex structure on the surface of the anode. The effective light-emitting area of the emissive layer is larger than that of a conventional device. That is, a higher brightness can be achieved by increasing the effective light-emitting area of the EL device. Also, the life span of the EL device is extended while keeping its brightness at a conventional level.
