In a back lighting device for a side light type panel, one end portion of a specular or light diffusing/reflecting film covering a linear light source is bonded to one end portion of a light conducting plate which is on the side of its light emerging surface and is in proximity of the linear light source, and a light diffusing/reflecting film is laid through an air layer on the part of the rear surface of the light conducting plate which corresponds to the junction. The back lighting device of the invention is small in size, large in effective light emitting area when compared with its external dimensions, and excellent in the distribution of luminance. Hence, it can be used as a back light device that is highly efficient in converting power to luminance.

摘要:
A back lighting device for a liquid crystal display has a light scattering coating in the form of dots covering the light emitting surface of a photo-conductive plate. The coating covers 3-50% of the surface nearest an end thereof adjacent a linear light source and covers 80-100% of the surface farthest from the light source. The variation of the coating rate across the surface produces uniform distribution of emitted light from the back lighting device.
摘要:
The plastic mold decapsuling apparatus comprises an etchant bottle; a heat tank; an etchant reservoir disposed in the heat tank; at least one decapsuling plastic mold holder; a first etchant feeding pump for selectively circulating the etchant from the etchant bottle to the etchant reservoir and discharging waste etchant; and a second etchant feeding pump for feeding the etchant from the reservoir to the plastic mold holder. Since the etchant bottle can be set as it is without transferring the etchant into another vessel, the etchant handling work is safe. Since a required amount of etchant can previously be heated in a reservoir within the heat tank, it is possible to continuously supply a predetermined amount of etchant heated to a constant temperature, thus improving the speed of decapsuling work. Futher, since the etchant is circulated through the decapsuling plastic mold holder, it is possible to firmly decapsule plastic mold devices by use of a relatively mild etchant such as fuming nitric acid.
