IPC: G02F1/13
Filed: 1992-03-05
Abstract: PURPOSE:To eliminate bright spot defects without decreasing the aperture ratio or increasing leaking of charges during off-time by forming a light shielding thin film on a display electrode to convert bright spot defects into black defects for a defective picture element electrode which gives bright spot defects during display. CONSTITUTION:A metal cobalt light shielding film 11 is formed, for example, to 3000Angstrom  thickness on an indium oxide (ITO) transparent picture element electrode 4 in the defect picture element part 10 having malfunctional thin film transistors 5. When this metal cobalt shielding film 11 is observed from the front surface of the liquid crystal display body, it wholly coveres the defective picture element part 10 with the light shielding layer 9 formed on a facing substrate 6. Thereby, even when the thin film transistor 5 does not operate in the defect picture element or no charge is given, light transmitting through the defect picture element part 10 is prevented. This gives no bright spot defects but black defects during operation of the liquid crystal panel.

Filed: 1989-02-28
Abstract: PURPOSE:To make it possible to effectively supply appropriate load power to an electric discharge lamp by selecting only one combination among combinations of feedback windings with a plurality of corresponding power supplies and installing power selection switches connected to an inverter. CONSTITUTION:Power selection switches 180, 182 connected to an inverter are installed by selecting only one combination among the combinations of feedback windings 136, 138 with a plurality of corresponding power sources 110, 116.

Filed: 1988-02-29
Abstract: PURPOSE:To improve the reliability of the quantitative measuring instrument by comparing a measured value of an unknown sample with the product of noise width and a factor and inhibiting the value from being displayed in case of being smaller than the product value. CONSTITUTION:When the factor K is inputted from an input means 11, a factor storage means 7 inputs and stores the factor K. A density calculating means 6 calculates density from the measured value F by using a calibration curve. The current measured value F is compared with the product K.N of the noise width N and factor K so as to judge whether or not the calculated density is secured. When the measured value exceeds the K.N, the measured value is displayed on a CRT together with the sample number. When the measured value is smaller than the K.N, it is decided that the density is not secured and the measured value is not displayed or displayed together with a warning mark as well as the sample number and density. Consequently, the reliability of the quantitative measuring instrument is improved.
