An image processing device includes: a gain calculation section determining a gain, on the basis of a first partial image in a first frame image that includes a process target line; and a correction section correcting pixel luminance information regarding the process target line, on the basis of the gain.

Display device, image processing device, and image processing method

A display includes: a display section; and a display driving section driving the display section based on a first image data set and a second image data set that alternate with each other. The display driving section drives the display section by performing a first scan with use of a first block as a driving unit in accordance with the first image data set and a second scan with use of a second block as a driving unit in accordance with the second image data set. The first block is composed of a plurality of consecutive pixel lines, and the second block is composed of a plurality of consecutive pixel lines and is different from the first block.

Display, image processing unit, and display method involving frame rate conversion and blur reduction

A projection type liquid crystal display unit includes (a) a first frame () having a first surface () formed with a first opening (), (b) a second frame () having a second surface formed with a second opening (), and (c) a liquid crystal display panel () sandwiched between the first and second frames () such that an incident light passes through the second opening (), the liquid crystal display panel () and the first opening () in this order. The first and second frames () are both composed of resin, and the first surface () of the first frame () is roughened.

Projection type liquid crystal display unit with reflected incident light

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.

Reflection type liquid crystal display device

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.

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.

Light conductor, lighting apparatus, and liquid crystal display

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.

A reflective or semi-transmissive type LCD device reduces a moir&#xe9; 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&#x2212;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&#x2212;1) modified basic irregularity patterns is formed by the N sub-patterns circularly shifted one by one.

Projection type liquid crystal display unit

A liquid crystal display device has a fluorescent lamp and a driving circuit as a back light. A closed container, a discharge gas sealed in the closed container, first discharge electrodes, and second discharge electrodes are included in the fluorescent lamp. The driving circuit repeats a first step of causing electric discharge in first discharge areas by applying a voltage having a negative polarity to the first discharge electrodes and a voltage having a positive polarity to the second discharge electrodes, and a second step of causing electric discharge in second discharge areas which are different from the first discharge areas by applying a voltage having a positive polarity to the first discharge electrodes and a voltage having a negative polarity to the second discharge electrodes.
