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. The light emitted by the light emission areas irradiate the LCD unit. The light reflected by reflective members of the LCD unit passes through the transparent areas of the organic EL layer and reaches to the viewer.

Fingerprint image entry device having no ground electrode provided in a position with which a finger is in a direct contact, wherein accurate fingerprint image can be entered independently of the initial electrostatically charged condition of the finger. The device comprises an electrode which is in the form of mesh or comb for radiating a high frequency wave toward a finger, a plurality of signal sensing electrodes for forming electrostatic capacitance between the electrodes and the finger and a signal switching means for consecutively connecting each of these signal sensing electrodes to a signal sensing circuit.

In an image sensor apparatus, a light emitting section is composed of a plurality of light emitting elements provided in a longitudinal direction of said image sensor apparatus. An optical section has an uneven structure, and changes the direction of light such that the light emerges from the optical section in a substantially parallel manner and converges to a linear region along the longitudinal direction. Here, the uneven structure includes a plurality of convex or concave portions, and a length of each of the plurality of convex or concave portions of the uneven structure in the longitudinal direction is smaller than a separation between adjacent two of the plurality of light emitting elements. An image sensor section transmits the converged light to a manuscript and for sensing a light reflected from the manuscript.

The present invention intends to provide a method for liveliness detection and fitness measurement using information optically extracted from a fingertip. For liveliness detection, the present method examines the change in a color index of a finger at its touching portion measured while the finger is being pressed onto an inspection surface and while the finger is released from the same surface. If the change is equal to or larger than a predetermined value, the finger is regarded as a live finger. For fitness measurement, an index indicative of the stiffness of the blood vessel of the finger is obtained from the change in the color index of the finger at its touching portion against the change in the contact area of the finger while the finger is being pressed onto the inspection surface.
摘要:
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. The thickness of the fingerprint input unit is approximately 1–2 mm, determined by the sum of the thickness of the planar light source and that of the color image sensor.

A conventional liquid crystal display comprises a number of components, so that a manufacturing cost cannot be reduced. Furthermore, a large-area substrate has problems in shipping. According to this invention, a liquid-crystal panel is prepared by forming individual optically functional films, a TFT device and a light-emitting device on a long thin film and then laminating the film by a transfer process. A base film to be a substrate in a liquid-crystal panel preferably has a thickness of 10 μm to 200 μm, a curvature radius of 40 mm or less as a measure of flexibility and a coefficient of thermal expansion of 50 ppm/° C. or less. Furthermore, it more preferably gives a variation of ±5% or less in mechanical and optical properties to a thermal history at 200° C.
