摘要:
Signal lines for supplying signal currents to respective pixel circuits having light emitting elements are arranged. A signal line driving circuit generates, on a signal line, a signal current corresponding to the image data, by switching bit weighting currents output from bit weighting current source circuits provided for respective bits of the image data, using a switch circuit turned on/off dependent on the corresponding bit. Each current source circuit has a function of correcting the level of the bit weighting current output from itself, based on a reference current of the bit weighting current supplied from a reference current line. Therefore, even when the characteristics of TFTs forming respective current source circuits vary widely, variation in signal currents among the signal lines can be suppressed, and unevenness in emission luminance can be suppressed.

An imaging apparatus including at least an imaging device having a plurality of photoelectric transfer devices arranged in matrix-shape to detect a light irradiated to each photoelectric transfer device and transfer to electric signal, and imaging means for imaging an image of a photogenic object on a surface of the imaging devices. The imaging means images at least two similar images of the photogenic subject on different area of the surface of the imaging device, and the imaging apparatus further includes electric signal processing means to form one image of photogenic subject from at least two images of photogenic subject. Since a plurality of images of photogenic subject can be formed on the imaging device by a plurality of image formation lenses, a thinner imaging apparatus can be realized.

Each of pixels arranged in a matrix is divided into sub pixels. Horizontal scanning lines and vertical scanning lines are arranged corresponding to rows and columns of the sub pixels, so that each sub pixel can be independently on and off. Each pixel includes a sub pixel connection circuit arranged between the sub pixels. A sub pixel connection circuit connects the pixel electrodes of corresponding sub pixels in accordance with a sub pixel connection signal input from a data line in synchronization with activation of vertical scanning line.

A method for manufacturing a thin-film semiconductor includes polycrystallization to focus visible light pulse laser into a line shape on a surface of an object to be irradiated, and repeat irradiation with displacing the visible light pulse laser such that a line-shaped irradiated region is overlapped with a region irradiated at a next timing in a width direction of the line-shaped irradiated region, to form a polycrystalline silicon film on the surface of the object. The step of polycrystallization applies ultraviolet light pulse laser onto a second irradiated region partially overlapping the first irradiated region while or before the visible light pulse laser is applied to the first irradiated region.

A spontaneous light emitting display device with low power consumption suppresses fluctuation in characteristics of driving elements of light emitting pixels and has no fluctuation in light emitting luminance of a light emitting element. For each of light emitting pixels arranged in a matrix, a respective photoelectric converting portion detects light emitted from the corresponding light emitting pixels is provided, so that a current flowing to the light emitting pixels is controlled by using a voltage produced from the respective photoelectric converting portion. The device suppresses luminance variation of the light emitting pixel even when the conversion gain of the photoelectric portion varies.
