Disclosed is a display device adapting a resolution improvement device capable of effectively improving a resolution in a projecting display device and a method thereof. A display device according to the present invention comprises: a light source; an image forming means for forming an image using a light emitted from the light source and an input image signal; a projection means for projecting an image formed in the image forming means on a screen; a displacement means for displacing an image displayed on the screen to be displaced; a driving means for driving the displacement to be moved; and an input signal applying means for applying an input signal to the driving means for the displacement means to be rotated in a predetermined direction. According to the present invention, different images are displayed on a screen periodically. It seems that the greater number of pixels is used than the real number in a sense of sight. Thus, the present invention has an effect of improving a resolution with the same number of pixels.

Display device and method thereof

A system for improving the resolution of a display device by using human visual characteristics wherein an image can be displayed at a more improved resolution than an actual physical resolution, thereby achieving the same effect as that where the resolution is physically improved. An image signal corresponding to one frame is separated into a first image signal and a second image signal, and a first image and a second image are formed based on the first image signal and the second image signal. The first image and the second image are respectively displayed at a first location and a second location. As a result, a viewer can view the image with an improved resolution.

Display device for improving an image resolution of projection-type display device

A concept of improving a resolution by using human's visual characteristics is provided. Bu the present invention, an image can be displayed at a more improved resolution than an actual physical resolution, thereby obtaining the same effect that the resolution is physically improved. An image signal corresponding to one frame is split into a first image signal and a second image signal, and a first image and a second image are formed based on the first image signal and the second image signal. Then, the first image and the second image are respectively displayed at a first location and a second location. As a result, a viewer can view the image at an improved resolution.

Display device having resolution improving apparatus for project-type display device

There is provided a projection display device with an angle shifter, in which the picture quality can be improved by reducing a visual pixel gap between an imaging element and a projection lens. The projection display device includes a light source for emitting a light, an imaging element for forming an image by using the light and an input image signal, a projection lens for enlarging and projecting the image on a screen, and the angle shifter disposed between the imaging element and the screen. The angle shifter periodically changes an incident angle of the light enlarged and projected on the screen. The angle shifter includes an angle shifting plate to visually remove gaps between the pixels of the imaging element.

Apparatus and method for projection type display

A light width controller is disclosed including a light width controlling mirror of a refractive index n2, the mirror having: a first surface of an angle a1 with respect to horizontal; a second surface of a different angle a2 with respect to horizontal; and a reflection layer for reflecting light incident on the second surface. The first and second surfaces are not parallel. Light that has passed through a medium of a refractive index of n1 smaller than n2 and then has passed through the first surface is incident upon, and then reflected from, the second surface. Also, an image projector utilizing such a light width controller is disclosed.

Light width controller and image projector employing the same

An image projector for obtaining a full color and cooling a lamp and the LCD, including a lamp for generating parallel light, an image displaying device for displaying a video signal, a rotating shaft rotatably disposed at the projector body, a steamboat paddle wheel-shaped color filter, disposed in such a way of receiving visual rays from the lamp onto its surface, for passing through light with a selected bandwidth having a predetermined wavelength such as Red, Green, Blue as well as simultaneously substantially cooling the image displaying device by fanning action; and a projection lens for forming an image displayed onto the image displaying device and onto a screen.

Image projector

A lamp changing system is an LCD projector, comprising a reflective facet, a rotary plate having a plurality of arc-tubes and blocks disposed thereon, and a cam member having an upper cam and a lower cam, whereby upon rotating the cam member, an old arc-tube is separated from and new arc-tube is replaced for the old arc-tube as a light source for the LCD projector.
