Problems solved by technology

[0010] Therefore, the resolution of the display device and the brightness of the 3D image are affected
In addition, since two projectors are used to form the images L and R, the volume of the device increases
Also, the projector needs to be enlarged to form a 3D image, and therefore, the manufacturing cost of the projector also increases

Embodiment Construction

[0030] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. The examples are described to aid in the understanding of the invention and are not intended to limit the invention in any way.

[0031] refer to figure 2 A projection system according to an embodiment of the present invention includes a projector 100 for enlarging and projecting an image formed by a display panel 105 and a screen 120 for providing a certain viewing area and displaying the image in a 3D image form.

[0032] The projector 100 includes a display panel 105 that processes incident light according to an input image signal to form an image, a polarization conversion device 110 that converts in synchronization with the image signal input to the display panel 105, and a projection lens that magnifies and projects the image onto a screen 120 Unit 115.

[0033] The display panel 105 may be a polarization-based liquid crystal display (LCD) or a ferro ...

Abstract

A screen and a projection system for producing a projection-type 3D image. The screen separates an image projected from a projector into fields for realizing a 3D image, and includes a birefringence device changing a refractive index according to a polarization direction of an incident beam and a lenticular lens array producing a 3D image using the beam that passed through the birefringence device.

Description

technical field [0001] The present invention relates to a projection-type three-dimensional (3D) image screen and a projection system including the screen, more particularly, to a screen that uses a projector to display a 3D image and improves the resolution of the 3D image, and a projection system including the screen system. Background technique [0002] 3D images are realized based on the principle of stereoscopic display. Binocular parallax, the characteristic obtained by separating the left and right eye positions from each other by 65 mm, is the most important factor in achieving the stereoscopic effect. The 3D image display can be displayed by using a display method with or without glasses. [0003] In the case of 3D image display using the wearing glasses method, the polarization directions of the left and right images on the projector are different from each other, and the user sees the 3D image by wearing the polarized glasses. Alternatively, the left and right ...
