Title: Back light unit
Inventor: SHIBATA KATSUHIKO
IPC: G02F1/133
Filed: 1992-07-17
Abstract: PURPOSE:To make the screen easy to see and reduce the power consumption by providing an automatic dimming circuit which analyzes display data and performs control so that the brightness is increased for a relatively dark gradational display or decreases for relatively bright hues. CONSTITUTION:Two right and left fluorescent tubes which are arranged in parallel across a light guide plate are put in a semicylindrical reflecting plate and their reflected lights face the light guide plate to operate as the light source of a liquid crystal display panel. A voltage which is supplied to the fluorescent tubes is adjusted to adjust the brightness as the back light unit. The automatic dimming circuit, on the other hand, receives hue data from a personal computer as a signal source and generates a control signal for setting the brightness low for bright hues whose mean value is high over the entire surface or high for dark hues. Thus, the brightness of the back light unit is automatically adjusted corresponding to the display screen to make the screen easy to see and the brightness is suppressed for the bright screen, so the power consumption is reducible.

CONSTITUTION:The surface of a semiconductor substrate including diffusion layer 12 and a thermal oxide film 13 is coated with a polycrystallien silicon 14 by a vapor phase growth method. After the first insulation film 17 such as a nitride film has been formed by a vapor phase growth method, the first insulation film 17 and polycrystalline silicon film 14 are selectively removed by etching except for a draw out electrode section and a wiring electorde section. Then, thermal oxidation is performed with the first insulation film 17 as a mask to form a thermal oxide film 18 only on the side of the polycrystalline silicon. Then, the first insulation film 17 grown only on the surface of the polycrystalline silicon electrode is removed by etching. The thermal oxide film 18 as the second insulation film is left without being etched so that the draw out electrode of polycrystalline silicon and the side of the wiring lectrode are coated with a thermal oxide film. After that, a polycrystalline silicon and metal silicide are formed in the same manner as in a conventional manufacturing method.

IPC: H01S3/08
Filed: 1990-07-19
Abstract: PURPOSE:To prevent the beam profile of a laser from being fluctuated and to enhance the stability of a pulse by a method wherein a grating is installed inside an airtight chamber. CONSTITUTION:The refractive index of a gas can be adjusted by changing the pressure of the gas or the composition of the gas inside an airtight chamber 7. Consequently, when the wavelength of a laser beam is fixed to a wavelength corresponding to the blaze angle of a grating 1, the grating 1 can be used at maximum efficiency and a narrow band can be achieved efficiently. As the grating 1, an echelle grating is optimum. At the grating, the vertical angle of grooves is nearly vertical and the grating having a large blaze angle can be manufactured. Its efficiency and its resolving power are high. Since a free spectral range is small, it is possible to easily adjust the laser wavelength inside the airtight chamber to a wavelength corresponding to the blaze angle.
