Abstract: Disclosed is a semiconductor device capable of realizing a reduction in the area of each pixel without degrading noise resistance. A switching transistor (13) and a signal accumulation capacitor (15) are formed on a semiconductor substrate (base semiconductor region) (11) of a first conduction type, on the basis of each unit region for constituting a pixel Px. The switching transistor (13) has a structure in which a source region (13S) and a drain region (13D) of a second conduction type are formed on the semiconductor substrate (11), and a gate electrode (13G) is formed on the region between the source region (13S) and the drain region (13D), with an insulating layer (12a) therebetween. The signal accumulation capacitor (15) has a structure in which high-concentration semiconductor regions (15D) and (15S) of the first conduction type are formed on the semiconductor substrate (11), and an electrode (15G) is formed on the region between the semiconductor regions (15D) and (15S), with an insulating layer (12b) therebetween. A structure may be adopted in which a bias semiconductor region (17) is not provided, and the semiconductor regions (15D) and (15S) are made to serve also as the bias semiconductor region.

Abstract: The method involves providing a first time period for application of an electrical signal for selecting one of two states, and a second time period for holding the selected state, either without application of the electrical signal, or with the application of an electrical signal for selection of none of the states using the memory characteristic of the ferroelectric liquid crystal or antiferroelectric liquid crystal during a common pixel selection period. The electric signal for selecting one of the two states is a pulse signal of positive polarity w.r.t. a reference level. The electric signal for selecting the other of the states is of negative polarity. A spatial light modulator and a method of driving a spatial light modulator are also claimed.

Abstract: PROBLEM TO BE SOLVED: To solve such a problem that potentials of two data lines making a pair can not be made equal to each other because of influences of a parasitic capacitance or the like of the data lines when the data lines are simply subjected to precharging at a reference voltage and hence operation of reading out a sustaining voltage of a pixel over two data lines to compare can not be accurately carried out. SOLUTION: The potentials of data lines 55-1, 55-2 making a pair are made equal to each other by supplying a predetermined DC voltage Vguard to data lines 55-1, 55-2 prior to reading out a first measurement signal TSIG1 from each unit pixel in a first pixel group (e.g. a group of pixels in a first column) to the first data line 55-1 and prior to reading out a second measurement signal TSIG2 from each unit pixel in a second pixel group (e.g. a group of pixels in a second column) to the second data line 55-2, and by short-circuiting the data line 55-1 and the data line 55-2 through a switch 46.

Abstract: PROBLEM TO BE SOLVED: To properly detect a defect of a pixel cell drive circuit before completion as a semiconductor device, even if the ratio of wiring capacitors to pixel capacitors increases.
SOLUTION: When a semiconductor device constituting a liquid crystal display is inspected, electric charges accumulated in pixel capacitors to be connected to a plurality of pixel switches selected from among all the pixel capacitors connected to one data line are read out of the same one data line, at the same time. Consequently, variations in the potential obtained on the data line can be made large. Then the potential variation obtained on the data line is amplified and outputted as a larger one, to be used for inspection. Consequently, potential variation, corresponding to a defective state of the pixel cell driving circuit, can be detected accurately in spite of a decrease in the ratio of pixel capacitors to wiring capacitors accompanying a smaller size or higher fineness of the liquid crystal display device.

Abstract: PROBLEM TO BE SOLVED: To display a high quality image by preventing image quality deterioration even when a display region is divided into a plurality of display regions in a display device in which writing time to a pixel is very short such as a liquid crystal display device of a dot sequential driving method using a single crystal silicon transistor as a switching device. SOLUTION: In a matrix driving type display device in which gate lines X in a column direction and data lines Y in a row direction are arranged in a matrix form and pixels P are arranged at intersections of the gate lines and the data lines, the display region is divided into two or more regions 1A and 1B driven independently from each other and wiring layouts of signal lines 8A and 8B which transmit display data (d) to respective regions 1A and 1B are made approximately symmetric with a division border line of the regions 1A and 1B as a center line. The display device is equipped with a control means 12 in which writing actions of the display data (d) to the pixels P adjoining each other across the division border line are performed almost at the same timing.

Abstract: PROBLEM TO BE SOLVED: To apply a scanning signal voltage (a gate voltage) that is equal to or greater than a breakdown voltage, to a switching element (a pixel switch) which drives a pixel cell while making the potential difference between pre scribed terminals of the switching elements to be equal to or less than the breakdown voltage, for example. SOLUTION: AVD1 which is equal to or less than gate breakdown voltage of a switching element and AVD2 which is equal to or greater than the gate breakdown voltage are selectively used as the voltage that scans scanning lines. Then, within a horizontal blanking interval, a data line is a precharged after scanning of the scanning lines is started by AVD1. Thereafter, the scanning voltage is changed to AVD2. A voltage corresponding to the precharging voltage is generated in a pixel capacitor. A potential difference which does not exceed the breakdown voltage is therefore generated between the terminals of the switching elements even though AVD2 which exceeds the breakdown voltage is applied to the pixel switch.

Abstract: PROBLEM TO BE SOLVED: To prolong the life of a light source, to realize excellent color reproduction, to improve the utilization efficiency of light, to reduce power consumption and to miniaturize the device. SOLUTION: Illuminating light beams of red, green and blue emitted from light emitting diodes 12R, 12G and 12B respectively pass through a relay lens and a field lens, irradiate video display light valves 11R, 11G and 11B, are spatially intensity-modulated, synthesized by a synthesizing prism 10 and enlarged and projected to a screen 17 by a projection lens 15. The shape of the light emitting parts of the light emitting diodes 12R, 12G and 12B is made the same as or similar to the shape of a video display area on the light valves 11R, 11G and 11B so that the shape of luminous flux irradiating the video display area on the valves may be the shape corresponding to the shape of the video display area on the screen.

Abstract: PROBLEM TO BE SOLVED: To facilitate control of brightness and to provide an electron emission source driven by a simple circuit, by achieving a simplified circuit design and low power consumption, and by keeping the stable amount of electron emission. SOLUTION: An electron emission source includes several current source circuits 24 and is provided with a current drive part in which each of the current source circuits 24 is electrically connected in parallel with a cathode electrode. In this electron emission source, a current flowing into the cathode electrode selectively drives the several current source circuits 24 which constitute the current drive part, and the amount of electron emission is set by discretely running current.

Abstract: PROBLEM TO BE SOLVED: To eliminate a battery effect to be a cause of asymmetry of a liquid crystal response, to dispense with offset voltage to be applied to driving voltage and to secure high reliability even when long term driving is performed, in a reflection type liquid crystal display element. SOLUTION: A coating layer 43 consisting of a conductive thin film of the same material as a transparent electrode is formed on the surface side opposed to the transparent electrode of a pixel electrode 42A. Thereby, the battery effect between electrodes opposed to each other is extinguished, asymmetry of the liquid crystal response is canceled and offset voltage conventionally needed is not needed. As a result, long term reliability when the reflection type liquid crystal display element is driven can be enhanced. COPYRIGHT: (C)2004,JPO
