摘要： A judging unit compares data in a dither table for each display pixel with a numerical value of low-order 2 bits of an input signal (12 bits) and outputs 1 to an adder when the numerical value of the low-order 2 bits of the input signal is larger than the data in the dither table, while outputting 0 to the adder in other cases. The adder adds the value outputted from the judging unit to an uneven luminance correction value read from a correction memory, so that the uneven luminance correction value is corrected. A multiplier multiplies the input signal by the uneven luminance correction value after the correction.

摘要： A liquid crystal display including includes a surface light source device of side light type for backlighting a liquid crystal panel. A primary light source supplies light to a guide plate. Emission from an emitting face impinges on a polarization separating element through a prism sheet. A polarization component which is directionally corresponding to a transmission polarization plane M12 is supplied to the liquid crystal panel. Reflection at the polarization separating element provides returning light which is subject to inside reflection by projection rows formed on a back face of the guide plate, thereby causing the guide plate to emit afresh recycling light. This recycling light, which is rich with the polarization component directionally in accordance with transmission polarization plane M12, impinges again on the polarization separating element. The projection rows formed on the back face run in a direction (first direction) which is generally vertical with respect to an incidence face of the guide plate while obliquely crossing with respect to both reflection polarization plane M2 and transmission polarization plane M12 of the polarization separating element. Projection rows formed on an inner face of the prism sheet run in another direction (second direction) which is generally parallel with respect to the incidence face of the guide plate. The polarization separating element and the prism sheet may be unified.

摘要： A light regulation element regulates both the travelling direction and diffusion state of a light emitted from a surface light source device. Lights from a cylindrical light source 2 such as a cold cathode tube is introduced in a light guide 1. The light guide 1 has an emission surface 1a on the side opposite to a reflection element 4, and a light regulation element 3 is arranged in opposition to the emission surface 1a. Protrusions 3a are formed on one surface or both surfaces of the light regulation element 3. Coated on the surface on the light emission side of the light regulation element 3 is a light diffusion layer 5. The turbidity of the light diffusion layer 5 falls within a range from 1900 cm−1 to 2400 cm−1 . The light emitted from the emission surface 1a of the light guide penetrates the light regulation element 3, thereby causing the light travelling direction to be regulated. Then, the light whose travelling direction has been regulated penetrates the light diffusion layer 5, thereby causing a light diffusion. The light diffusion layer 5 is formed, for example, by mixing fine particles of a glass having a light penetrability or of a synthetic resin such as acryl and silicone, or fine hollow particles of glass, acryl resin or the like, or air bubbles in a coating material having a light penetrability.

摘要： A light incident into a wedge type light scattering conducting element from a light incident surface of the light scattering conducting element is converted into a light flux having a directionality and is output from a light output surface. The output light is input to a wedge type emitting direction characteristic adjusting element arranged with a positional relationship complementary to the light scattering conducting element. A prism shaped irregularity for adjusting a propagating directionality of the light in longitudinal/transverse directions is formed on a light input surface/light output surface of the wedge type emitting direction characteristic adjusting element. The wedge type emitting direction characteristic adjusting element has a weakened scattering power depending on requirements, thereby a degree of directionality sharpness of the light emitted from a surface light source device is adjusted. Various modifications are provided for the light scattering conducting elements, and regions having different scattering powers are combined for various patterns. The device is useful for A backlight source.

摘要： A wedge shaped parallelized light flux element made of a light scattering guide of an emitting directionality has a specified ranged effective scattering irradiation parameter and correlation distance "a". A light incident into the parallelized light flux element from a fluorescent lamp arranged facing a light incident surface of the parallelized light flux element is emitted from a light output surface as a parallelized light flux G1 by composite factors including forward scattering of the inside, repeated reflection on wedge shaped two sides, critical angular condition and boundary face transmittance for the light output surface. A total amount of parallel light flux G1 emitted from the parallel light flux emitting section F is reflected on a two side prism surface of two prism reflection element PR thereby being converted into sectional area enlarged light fluxes G2 and G3. They are incident on a liquid crystal panel LP through a light diffusion plate DF, and utilized as a backlight. Reflective appearance of a light supply source for supplying a light to the light scattering guide is prevented by forming a reverse slope portion or the like on back surface of the light output surface in adjacent to the light incident surface of the parallelized light flux element.

摘要： This invention relates to the shape of a skirt below the piston head of a piston in an engine cylinder and continuous with it. The skirt has a basic configuration comprising at least two type of elliptical horizontal cross-section with a short axis parallel to said piston pin, and a barrel-shaped vertical cross-section smaller at its top and bottom. A T-shaped projection is also provided on the lateral surfaces of the skirt corresponding to the two ends of the long axis of said ellipse, this projection consisting of a vertical piece and two side pieces situated on either side of the vertical piece. When the engine is running, the skirt comes into contact with the inner surface of the cylinder via this projection. The vertical section of the lower part of the skirt from below the lower edge of the two side pieces to the lower edge of the skirt is inclined toward the inside of said barrel-shaped vertical section so that the skirt is joined smoothly to the projection below the two side pieces. Accumulation of pressure on the edge of the projection is thereby prevented, which reduces frictional resistance and prevents wear between the piston and the cylinder.
