Abstract: PROBLEM TO BE SOLVED: To obtain a metal oxide conductor this film, which is low in specific resistance, is low also in light transmittance, is low in the contact resistance between the conductor thin film and a copper thin film, has little irregularity in the contact resistance and has uniform characteristics. SOLUTION: A metal oxide conductor thin film which has a thickness of 1000 to 1200 Å, a specific resistance of 300 to 400 Ωcm, a light transmittance of 85% or higher and the contact resistance between the conductor thin film and a copper thin film of 1.0×10-6 Ωcm or lower is formed. Such the metal oxide conductor thin film is obtained by a forming method, where at the beginning of the formation of the conductor thin film, the conductor thin film is formed by a sputtering method in a non-oxidizing atmosphere, then the conductor thin film is formed by the sputtering method in an oxidizing atmosphere containing enriched oxygen. By adopting this conductor thin film, as the specific resistance of the conductor thin film is low and the light transmittance of the conductor thin film is high in the case where the conductor thin film is used as a transparent pixel electrode, the conductor thin film has the advantage capable of obtaining a high-luminance liquid crystal display image plane. Moreover, in the case where the conductor thin film is used as a protective film for the terminal parts of a liquid crystal display device, as the contact resistance between the conductor thin film and a copper wiring is low and an irregularity in the contact resistance is also little, the conductor thin film has the advantage capable of obtaining the liquid crystal display device of a stable operation.

Abstract: PROBLEM TO BE SOLVED: To obtain a data interface device, a panel driver and a monitor where EMI can be suppressed by transmitting data in a way that a transmission rate can be changed within a prescribed range of the transmission rate. SOLUTION: In a liquid crystal display panel driver, a source drive IC 22 is connected to a timing controller 26 through 1st and 2nd buses, and a frequency divider 30 is provided between the timing controller 26 and a clock modulator 28. R, G, B data as to odd number order pixels are fed to the source drive IC 22 through a 1st internal bus FIB and R, G, B data as to even number order pixels are fed to the source drive IC 22 through a 2nd internal bus SIB. Thus, the timing controller 26 can separate odd number order pixel data from video data ERD, EGD, EBD received from an external bus. Data delivered through the 1st and 2nd internal buses have a frequency that is a half of data on the external bus.

Abstract: PROBLEM TO BE SOLVED: To increase a display area of an image display panel and reduce the number of components by inserting a flat display module into a hinge frame. SOLUTION: A side wall 11 of a liquid crystal display module 10, that is, a metal sash is formed with a plurality of recesses 12, 13. A hinge frame 60 is formed with fixed projections 61, 62 at places corresponding to the recesses 12, 13 of the liquid crystal display 10 to be inserted into the recesses 12, 13. The recesses 12, 13 and the fixed projections 61, 62 can be formed in the square pillar shape or any other shape. The recesses can be formed directly in the side wall 11 of the metal sash. However, a recess-formed member can be installed on the side wall 11 of the metal sash to prevent the damage of the metal sash. Due to this structure, the number of components can be reduced. Moreover, even when the liquid crystal display cannot be supported by screws because of a small thickness of the display, it can be joined to the hinge frame by the side faces.

Abstract: PROBLEM TO BE SOLVED: To make it possible to remove flicker and after-image and to simplify circuit constitution by providing a gate driver or the like capable of outputting one of a first voltage and a second voltage and allowing the first voltage to change before continued gate signal lines are activated. SOLUTION: The device has a data driver 32 for driving signal lines SL1-LSm provided on a liquid crystal panel 30 and a gate driver 34 for driving gate lines GL1-GLn provided on the liquid crystal panel 32. Further, relating to this active matrix liquid crystal display device, the falling part of scanning signal is changed in a form selected from linear, exponential and step functions by supplying a high gate voltage to a level shift of the gate driver 34 in the alternating current form. Thereby, a field through voltage is sufficiently suppressed and then formation of flicker and after-image can be avoided and, at the same time, the circuit constitution is extremely simplified.
