Image display apparatus and image display method

Abstract

An image display apparatus that displays an image on the basis of image signals of sub-pixels of first, second, and third color components forming a pixel includes a first light modulating unit that modulates light of the first color component on the basis of the image signal of the sub-pixel of the first color component, a second light modulating unit that modulates light of the second color component on the basis of the image signal of the sub-pixel of the second color component, and a third light modulating unit that modulates light of the third color component on the basis of the image signal of the sub-pixel of the third color component. The first to third light modulating units are provided such that display sub-pixels corresponding to the sub-pixels that use the lights modulated by the first to third light modulating units shift in a first direction that is a horizontal direction or a vertical direction of the image.

Description

technical field [0001] The present invention relates to an image display device and an image display method. Background technique [0002] In recent years, high-performance image display devices such as large-screen televisions and projectors have spread widely, and in these image display devices, high-quality display images have become more important. In order to increase the image quality of such an image display device, it is necessary to improve the sense of resolution of a person observing a displayed image. [0003] Patent Document 1 discloses a technique for improving the brightness, resolution, and the like of a screen by combining two projectors and synthesizing the display screens of the projectors. More specifically, disclosed is a technique of shifting the sub-pixels of two images by half a pixel and overlapping the images to form one image. [0004] Furthermore, Patent Document 2 discloses such a projector: in addition to the three primary colors of R, G, and ...

AI Technical Summary

Problems solved by technology

[0007] However, in the technique disclosed in Patent Document 1, since two projectors are used, there is a problem of cost increase.

[0008] In addition, in the technology disclosed in Patent Document 2, since it is a so-called four-panel type, it is necessary to prepare four liquid crystal display devices, and there is a problem of cost increase.
