Patent JP-2002236301-A (JP)
Title: Continuous light source
Inventor: YAMADA HIDEKAZU
IPC: H01S5/065
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a multi-wavelength continuous light source or a single- wavelength continuous light source with a favorable SN ratio. SOLUTION: By using a distributed Bragg reflector-accumulated mode-locked semiconductor laser 31, a large number of continuous light beams with a favorable SN ratio can be generated. By using a normal dispersion flat optical fiber 33, little degradation of the SN ratio is caused over the whole region of a spread spectrum, the intensity of the generated continuous light is made large, and the variation of the light intensity depending on the wavelength is minimized. The optical frequency spectrum of a repetitive light pulse train generated with the laser 31 consists of the longitudinal modes of a frequency interval corresponding to the repetition frequency. When this pulse train is amplified with a light amplifier 32 and sent into the normal dispersion flat optical fiber 33 by maintaining a large intensity, the optical spectrum turns into a broadband optical spectrum while the pulse train is propagating through the optical fiber. The single-wavelength- or the multi-wavelength continuous light source is obtained by taking out one or a large number of one longitudinal mode from the broadband optical spectrum by using a wavelength demultiplexer 34.

Title: Method for driving display device, and display device using the method
Inventor: TSUDA KAZUHIKO
IPC: G09G3/36
Filed: 2001-03-01
Abstract: PROBLEM TO BE SOLVED: To drive a matrix type display device while making sufficient power reduction and high display quality sufficiently suppressive in flickering compatible. SOLUTION: In a pause period T2, the potentials of data signal lines and a counter electrode of a liquid crystal panel are made almost equal to the respective centers of the voltage amplitudes in a scanning period T1. Thus, the effective voltages applied to the liquid crystal layer are almost equalized both in the scanning period T1 and the pause period T2. Moreover, in the pause period T2, AC-driving of the counter electrode is stopped first (point d), and then a source driver is brought into high impedance state (point e). Thus, a steady-state current flowing through an amplifier in the source driver in the pause period T2 can be reduced. Therefore, low power consumption can be achieved while eliminating the flickers generated in each scanning period T1 and keeping favorable display quality.
