  • Patent number: 7391488
    Abstract: In a reflection type liquid crystal display device having a front light and a reflection type liquid crystal panel including a reflection electrode of uneven structure, average tilt angles of the uneven structure of the reflection electrode are changed to form a high directivity reflective region having a characteristic reflecting an incident light from the front light in a vertical direction and a wide viewing angle reflective region having a characteristic reflecting an outside light incident slantingly from the front in a vertical direction, thereby forming the high directivity reflective region and the wide viewing angle reflective region to be mixed in the reflection electrode in the same display device.

  • Publication number: 20060274162
    Abstract: An image processing apparatus has: a frame memory storing a signal of a previous image in a previous one frame, and a correction processing unit configured to receive signals of the previous image and a current image, correct a signal level of the current image based on a difference of signal levels between the previous and current images, execute the correction by applying a first correction mode where a relationship between the signal level of the previous image and an amount of correction of the signal level of the current image is common to three primary colors or a second correction mode for correcting the current image by applying another amount of correction so as to complete an optical response of liquid crystal in the entire primary colors within one frame display period when an input image transits from the previous image to the current image.

  • Patent number: 7119860
    Abstract: A light-reflection type liquid crystal display device includes (a) a liquid crystal display panel, (b) a polarizer mounted on the liquid crystal display panel, (c) a light-guide mounted on the polarizer, (d) a resin layer sandwiched between the polarizer and the light-guide for fixing the polarizer and the light-guide to each other, (e) a light-source arranged adjacent to an end of the light-guide for supplying light to the light-guide, and (f) a frame having a bottom and a wall defining an opening which has the same contour as that of the light-guide. The light-guide is positioned relative to the polarizer by being lowered along an inner wall of the frame through the opening onto the polarizer.

  • Patent number: 7066635
    Abstract: Light is input into an incident surface portion from a fluorescent lamp, and most of the light propagates in repetition directions. Since a length of an emission portion of the fluorescent lamp is shorter than that of the incident surface portion, there are areas to which no light propagates and dark portions generate in the repetition directions of a string of prisms. Since these dark portion generate out of the display area, a display quality is improved.

  • Patent number: 6993820
    Abstract: A method is provided for manufacturing a support frame of a rectangular display panel within a short working time. The method includes a process of taking out L-shaped component members each having convex portions and concave portions arranged alternately at an end portion in a manner that each of the convex portions and concave portions is bilaterally symmetrical, while a shear droop and a burr are formed on an end portion and process of fitting and coupling end portions of L-shaped component members by placing the convex portions and the concave portions in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions and that that the convex portions and the concave portions are pushed towards each other and by pressing the convex portions and the concave portions using a pair of metal molds.

  • Patent number: 6980271
    Abstract: A reflective or semi-transmissive type LCD device reduces a moiré generated by the irregularity pattern of the reflector plate of the LCD panel. A front light has an optical guide plate in which prism grooves are arranged in an arrangement direction. The pattern of the reflector plate is formed by blocks, each of which includes a basic irregularity pattern for one pixel or its element, and (N?1) modified basic irregularity pattern or patterns each formed by modifying the basic irregularity pattern. All the basic irregularity patterns in each block are arranged in a direction perpendicular to the arrangement direction. The basic irregularity pattern is continuous at either end thereof in the arrangement direction. The basic irregularity pattern is divided in the arrangement direction into N sub-patterns. Each of the (N?1) modified basic irregularity patterns is formed by the N sub-patterns circularly shifted one by one.
