摘要： Input/output areas of device elements are provided at opposite ends of the original substrate, and two function areas are provided between the opposite input/output areas. The original substrate composing a large-size device is cut along lines in such a way that the input/output areas and the function areas are separated from one another. As a result, those portions of the original substrate where no function areas are to be formed are reduced, thereby contributing to effective utilization of the surface of the substrate for increasing the number of sensor substrates that can be yielded from it. The process is improved in the shape and layout of the substrates for electronic devices to be obtained by cutting the large-area device formed on the substrate and it hence is capable of yielding a greater number of electronic device elements from the large-area device.

摘要： A measurement pattern is moved on a display, and an image of the measurement pattern is captured by making a visual field of an image sensor follow the scroll of the measurement pattern. On the basis of the captured image, a motion picture response curve is obtained. Then, the motion picture response curve is transformed into an MTF (modulation transfer function). A normalized spatial frequency value N_Sf(a %) at which an MTF value starts declining by a predetermined percentage from a highest luminance portion of the MTF is determined. Then, the motion image quality of the display is evaluated on the basis of the normalized spatial frequency value N_Sf(a %). Thus, the evaluation of the motion image quality of the display can be achieved on the basis of an intuitively understandable motion image quality evaluation index.

摘要： A test pattern is moved on a screen 5 subject to measurement with the field of view of an image sensor pursuing the motion of the test pattern so as to observe BEW. Subsequently, the field of view 33 of the image sensor is moved at the same velocity vc as in the foregoing observation to capture an image of a static pattern PE, and a blur width W along the scrolling direction that appears in a distribution profile of the captured image is observed. Based upon the blur width W and the exposure time of the image sensor for capturing the image of the static pattern PE, the moving velocity of the test pattern at the time of observation of the BEW is estimated, and by using the moving velocity, the BEW is normalized. Evaluation of the moving image quality of the screen is carried out by using the normalized N BEW. The moving velocity of the original test pattern can thus be estimated easily and accurately, and accordingly, the moving image quality of the screen can be evaluated accurately.

摘要： Impurity is removed from gas, the resultant gas is introduced into a cell 15, and the intensity of light transmitted through the cell 15 is measured as a reference. Gas containing impurity of which concentration is known, is introduced into the cell 15, and the intensity of light transmitted through the cell 15 is measured with the temperature and pressure maintained at those used at the measurement of the reference light intensity. Then, the absorbance of the impurity is obtained according to the ratio of the two light intensity data obtained by the two measurements above-mentioned. The impurity absorbance thus obtained is stored, in a memory 20a, as a function of an impurity concentration. Gas containing impurity of which concentration is unknown, is introduced into the cell 15, and the intensity of light transmitted through the cell 15 is measured with the temperature and pressure maintained at those used at the measurements above-mentioned. The absorbance of the impurity is obtained according to the last-measured light intensity and the reference light intensity. The absorbance thus obtained is applied to the function, thereby to obtain the impurity concentration.

摘要： A screen motion image quality measuring/evaluating apparatus according to the present invention comprises: a rotatable mirror 2; a camera 3 for capturing a screen through the mirror 2; and a control unit 6. The control unit 6 is arranged to control such that when it is detected based on a change in the luminance of a screen 5 that a test pattern contained in a motion image displayed on the screen 5 has passed a predetermined position of the screen 5, a trigger for rotation is given to the mirror 2, and such that after the start of rotation of the mirror 2, the mirror 2 rotates as keeping pace with the movement of the test pattern. Without electric synchronism of rotation with a motion image signal, a trigger for rotation can be given to the mirror 2. Thus, the quality of a motion image on the screen can be measured with a simple structure.

摘要： A system is disclosed, which comprises a rotatable mirror 2, a camera 3 for taking an image of a screen 5 through the mirror 2, a photodetector 4 having a detection range covering a part of the screen 5, and a control section 6. At a time when a measuring pattern included in a moving image displayed on the screen 5 is detected by the photodetector 4, a detection signal is outputted from the photodetector 4. Based on the detection signal, the control section triggers the mirror 2 to rotate, and after the mirror 2 starts rotating, the control section 6 controls so that the mirror 2 rotates to follow the motion of the measuring pattern. It is possible to obtain images that trace the motion of the moving image on a detector plane of the camera 3 without resorting to electrical synchronization of the rotation of the mirror and moving image signals, and to measure the moving image quality of displays with a simple structure.
