    摘要： A liquid crystal device has a light source and liquid crystal elements which selectively transmit light emitted by the light source. The liquid crystal device comprises: the light source, being an electroluminescent device, having a transparent electrode disposed on a light output side of the light source, an electrode opposite to the transparent electrode, and an electroluminescence emission layer interposed between the transparent electrode and the opposite electrode; voltage supply means connected to the transparent electrode in order to feed a reference voltage to the transparent electrode; and driving voltage application means for applying a driving voltage to the opposite electrode. The driving voltage application means comprises a separate excitation type driving circuit using the capacitance of the electroluminescent device itself to produce an alternating current, and pulse generating means for generating a pulse responsive to an input signal to turn on and off a switch of the separate excitation type driving circuit. The pulse generating means includes a multivibrator and a capacitor and a resistor determine the width of the pulse.

A second photosensor portion includes a plurality of photoelectric converting devices and provides reference signals from light reflected from a reference member, or light received directly from a light source.

Preferably, reference signals from the converting devices of the second photosensor are used by the correction circuitry to correct the electrical signals from substantially adjacent converting devices of the first photosensor portion. A single converting device of the second photosensor portion may be used to correct either one or more of the converting devices of the first photosensor portion.

    摘要： An electroluminescent device comprising a first electrode, a second electrode and an electroluminescence emission zone, the electroluminescence emission zone being made of a first electroluminescence emission layer, a second electroluminescence emission layer, and a transparent electrode which is interposed between the first electroluminescence emission layer and the second electroluminescence emission layer. At least either the first electrode or the second electrode is a transparent electrode. The first electroluminescence emission layer and the second electro luminescence emission layer emit light by applying a driving voltage to the transparent electrode with both the first electrode and the second electrode connected to a power supply for a reference voltage. In an image sensor using such an electroluminescent device as a light source, the electric field produced by the driving signal of the electroluminescent device does not escape outward, presenting no interfering noise to the image sensor. The resulting light quantity is almost double that of devices with only a single electroluminescent layer, substantially enhancing a resulting image. As a result, a high S/N ratio image sensor may be fabricated.

    摘要： To eliminate non-read time in a photoelectric converting device, a photoelectric converting section is provided in which a plurality of photoelectric conversion elements, switching elements, matrix signal wirings, and gate drive wirings are arranged on the same substrate such that the photoelectric converting section generates parallel signals. A drive switching section is provided for applying drive signals to the gate drive wirings. A read switching section is provided for converting the parallel signals which are transferred from the matrix signal wirings into a serial signal, and for outputting the serial signal. The read switching section comprises a plurality of transfer switches respectively connected to the matrix signal wirings. The transfer switches are preferably activated together, simultaneously. A plurality of read capacitors are also provided in the read switching section to store the charges transferred through the matrix signal wirings. The read switching section also includes a plurality of read switches for reading out carriers stored in the plurality of read capacitors. The read switching section also includes reading circuitry for reading the read switches by sequentially switching the read switches so that a period of driving the transfer switches and a period of driving a first one of the read switches are partially overlapped.
