摘要： The present invention relates to an improved solid-state imaging device having pixel amplifiers. The higher definition of the device results in the increase in number of pixels as large as not less than two million. When a solid-state imaging device having such a large number of pixels is provided with pixel amplifiers, there arise various problems associated with a power source and a power supply line as well as a problem inherent to the pixel amplifier type of solid-state imaging device. The present invention provides a solid-state imaging device in which noises or the like are prevented and a picture or image quality having high definition can be obtained, by suppressing a voltage drop of the power supply line and by compensating fluctuations in outputs of the pixel amplifiers.

摘要： A solid-state imaging device includes a vertical CCD shift register for transferring electric charge. The electrode of the vertical CCD located nearest to the substrate is extended outside of the region of the vertical CCD to a region of a layer where isolation is required. The layer is thus imparted with two functions, that is, the function of the CCD electrode and that of the iolation electrode. An overflow transistor is also provided to discharge excess charge produced by high intensity light.

摘要： A solid-state imaging device is constructed by integrating a plurality of face plate elements of an imager in the shape of a matrix on a semiconductor substrate. The face plate elements are formed of photodiodes, in which charges corresponding to incident light are accumulated. The charges are converted into currents or voltages by a plurality of amplifying means disposed in the matrix and which are provided adjacent to the photodiodes. The currents or the voltages obtained through conversion are delivered out of the matrix through signal lines. To the signal lines a correlated double sampling circuit is connected, and this curcuit detects a difference in outputs of the amplifying means between a case when the charges of the photodiodes are not present in the input portions of the amplifying means and a case when they are present therein.

摘要： In a display mode, a signal driving circuit (DAC) transmits image signals to the pixels selected by a scanning circuit for display and first switches of switch units. Then, a power supply circuit supplies a current corresponding to the transmitted signal to the pixels. Then, organic EL elements provided in the pixels are driven to emit light, thereby displaying an image. In order to correct the deterioration of the organic EL elements, first, a constant current flows from a current source to the organic EL elements of the pixels selected by a scanning circuit for detection and second switches and a voltage corresponding to the constant current applied to the organic EL element is detected. The detected voltage is input to an AD converter through a buffer amplifier, and the AD converter converts the voltage into a digital value, and transmits the digital value to a signal correction control unit. When the organic EL element deteriorates, the detected digital value varies. Therefore, the signal correction control unit corrects the signal from the signal driving circuit, thereby correcting the deterioration of the organic EL element.
