  • Patent number: 6816140
    Abstract: A displaying device, which can reduce the power consumption, compared with a conventional displaying device in which the reduction of the power consumption is difficult because light is extracted from each of light emitting elements in time series, and also can prevent a displayed image from deteriorating caused by light entering from the outside or a light loss in a waveguide array, is provided. In the displaying device, a light emitting array controls each of light emitting elements. A waveguide array is formed by patterning a photosensitive resin formed on a supporting substrate having a light absorbing layer. A light extracting section extracts light at the same time form a predetermined selected region of the plural light emitting elements. The light extracting section also provides an antireflection layer on the surface facing to an observer. The extracting efficiency at the light extracting section is corrected corresponding to a light loss in the waveguide array.

  • Patent number: 6781647
    Abstract: A LCD device includes a LCD unit and a front light unit disposed in front of the LCD unit. The front light unit has a transparent electrode, an organic EL layer and a patterned non-transparent electrode. The non-transparent electrode has a mesh structure for defining light emission areas and transparent areas of the organic EL layer, which are arranged alternately.

  • Publication number: 20030044051
    Abstract: A color image sensor sequentially acquires a plurality of fingerprint images when a finger is pressed against the detector surface. A color information extraction unit detects the finger color in synchronization with the input of the plurality of fingerprint images. An areal information extraction unit detects a physical quantity representing the pressure applied by the finger to the color image sensor when the plurality of fingerprint images are acquired, particularly, the quantity related with the area of the finger in contact with the detector surface. A living body identification unit determines whether the finger is a live or dead one by the analysis of correlation between the physical quantity and the finger color. According to this configuration, even if the finger color does not change much, it is possible to distinguish living bodies from dead ones if there is a sufficient correlation with information such as the area of the fingerprint that reflects the finger pressure.
