Abstract: PROBLEM TO BE SOLVED: To provide a cold cathode fluorescent lamp apparatus easily lighting and having little leak current. SOLUTION: A cold cathode fluorescent lamp 10 is provided with an internal electrode 17c and an internal electrode 17d disposed on an inner face, and an external electrode 18a and an external electrode 18b disposed on the outer face side. The internal electrode 17c and the internal electrode 17d are driven by a DC driving circuit 22, and the magnitude of a current is controlled by a constant current circuit 23. The external electrode 18a and the external electrode 18b are driven by an AC driving circuit 26. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To improve viewing angle characteristics of a liquid crystal display, and also improve a display characteristic of a moving image. SOLUTION: The image display apparatus 10 includes an interpolation part 11 for up-converting a screen rate, an overdrive part 12, a viewing angle improvement processing part 13 which converts one gradation of an input video signal into a video signal expressed by composition of liquid crystal densities of two or more temporally continuous fields, and a source driver 15 for driving the liquid crystal display 16. The viewing angle improvement processing part 13 converts the input video signal into a video signal composed of a 1st field set to a signal value corresponding to a higher gradation and a 2nd field set to a signal value corresponding to a lower gradation. The overdrive part 12 corrects the level according to the response of the liquid crystal to (a) signal value(s) of one or both of the 1st and 2nd fields, if a temporal change in the gradation occurs on the input video signal in the same spatial position.
