摘要： A white cold-cathode fluorescent lamp, which is used as an illumination backlight for liquid crystal, is replaced by cold-cathode fluorescent lamps that emit red, green and blue lights, respectively. Since a liquid crystal picture is illuminated by the fluorescent lights in a time-sequential manner, a multi-color display can be provided without spatially dividing liquid crystal pixels using a color filter; and as it is not necessary for one pixel to be divided into three color cells, the size of a pixel can be reduced. Furthermore, in the liquid crystal display device, a phosphor having a short emission life is employed to coat the interior of the cold-cathode fluorescent lamp and enable the cold-cathode fluorescent lamp to be turned on and off rapidly, so that degradation of display colors due to slow fluorescence decay can be prevented and moving pictures can be displayed.
摘要翻译： 用作液晶的照明背光的白色冷阴极荧光灯由分别发出红色，绿色和蓝色光的冷阴极荧光灯代替。 由于液晶图像以荧光灯以时间顺序的方式照亮，所以可以提供多色显示器，而不需要使用滤色器空间分割液晶像素; 并且由于不需要将一个像素划分为三个彩色单元，因此可以减小像素的尺寸。 此外，在液晶显示装置中，采用具有短发光寿命的荧光体来涂覆冷阴极荧光灯的内部，并使得冷阴极荧光灯能够快速地导通和关闭，使得显示器的劣化 可以防止由于慢荧光衰减引起的颜色，并且可以显示运动图像。

摘要： This invention provides a method and apparatus for accurately measuring the flying height of a magnetic head at high speed by using a white lamp and a color CCD camera. The invention entails substituting tentative refraction coefficients and extinction coefficients representative of colors in theoretical equations expressing the relationship between interference light intensity and flying height, thereby optimizing the parameters by non-linear regression. The flying height of a magnetic head is measured by using the coefficient thus determined. Also, this invention enables determination of flying height at very high speed through effecting the above optimization in consideration of constants associated with the shape of the head under consideration, and adapting the above theoretical equations.

摘要： A high-sensitivity apparatus having simple constitution that measures the flying height of a magnetic head. Light emitted from a white light source 25 is directed to the gap between a disk 23 and a head 21, and subjected to multiple reflection between the disk 23 and the head 21. Reflected light from an opaque object, which may be either the disk 23 or the head 21, is divided into at least three components having respective wavelength regions which are directed to different photodetectors 35, 36, and 37 for the respective wavelength regions. An estimation device 38 estimates the flying height of the head according to the least-square method from the outputs of the photodetectors using functions prepared in advance for the respective wavelength regions, and correlates the disk-head gap and the reflected light intensities detected by the respective photodetectors. Real-time calculation according to the least-square method is performed by means of a table look-up technique or a tracking servo technique.
