Title: Optical transmitter
Inventor: AOKI MASAHIRO
IPC: H04B10/516
Filed: 2003-01-14
Abstract: <P>PROBLEM TO BE SOLVED: To realize an economic optical transmitter or particularly a high performance optical transmitter using a multiple quantum well type MZ modulator which is suitable for a high speed optical transmission and has a simple structure, and more particularly to generate a high speed optical signal of high signal quality in which the cross point of an optical waveform is disposed at a center between a mark and a space in response to the change of operating conditions.  <P>SOLUTION: The cross point position of a modulated light is controlled by deviating the cross point position in the rise/fall of the output electric signal of an optical modulator driver circuit from a center in the non-linearity of the modulation curve of the MZ modulator using the multiple quantum well type. Even when the design, etc. of not only the cross point regulation under predetermined conditions but also the operating wavelength, the operating temperature and the multiple quantum well structure, are changed, the cross point regulation is realized by the same method. Particularly, the push-pull operation of the feature of the MZ modulator is realized.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Character display method and system
Inventor: IWATA SATOSHI
IPC: G09G3/36
Filed: 2003-01-23
Abstract: <P>PROBLEM TO BE SOLVED: To display characters of high quality with a display system of low contrast by resetting RGB values gradated according to a view angle of a display panel.  <P>SOLUTION: In this flat panel display system composed of a rectangular subelement of RGB, character images are inputted, gradated to gradated values of a subpixel corresponding to the subelement of the display system by applying a given smoothing treatment, to convert pixel unit coordinates into rectangular RGB element coordinate. When an angle viewing one element of the display system (view angle) has a certain value or higher, the character contrast is emphasized by a contrast enhancement function, to reset luminance of the subpixel adjacent to the character body to a lowest luminance. Thus, the area of the lowest luminance level is enlarged to improve the character contrast. In place of using the contrast enhancement function, the luminance of the subpixel may be reset by a resetting table constituted of resetting values.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
