Embodiment Construction

[0039]The term 3-D or 3D may be used to describe a visual representation or display technique for reproducing three-dimensional moving images with an optical illusion of depth. Given an image for the left eye and an image for the right eye, the viewer's visual cortex can analyze the two images into a three-dimensional image.

[0040] Three-dimensional (3D) display technology employs 3D image processing and presentation technology for devices capable of displaying 3D images. Instead, a device capable of displaying 3D images should use special viewing equipment to present three-dimensional images to the viewer.

[0041] Examples of 3D image processing and rendering may include stereoscopic image / video capture, multi-view image / video capture using multiple cameras, processing of two-dimensional images and depth information, and the like. Examples of devices capable of 3D image display may include liquid crystal displays (LCDs) provided with suitable hardware and / or software supp...

Abstract

The present invention provides a 3D LCD using a spectrum method. The 3D LCD which forms and displays a 3D image using light sources comprises: a 1st light source that forms an image for a left eye; a 2nd light source that forms an image for a right eye; and a control unit that is connected to the 1st and 2nd light sources and drives the light sources in turn, wherein the RGB spectrum bands of each light source overlap to a degree that does not cause interference between the RGB spectrum bands. Preferably, the 1st and 2nd light sources include an LED. More preferably, the 1st and 2nd light sources are installed on a light source unit for a back light unit. Selectively, the 1st and 2nd light sources comprise at least one light source body respectively. Therefore, the invention can: produce a 3D image of which brightness and definition are more improved than a 3D LCD using a polarization method; display the 3D image at a cheaper cost than a 3D LCD using a time-sequential method; and improve user satisfaction by increasing user convenience. In addition, the invention is able to simplify the fabrication processes of the 3D LCD and reduce fabrication costs as the 3D image can be produced through the spectrum method by using little-changed conventional LCD production processes.

Description

technical field [0001] The present disclosure relates to liquid crystal displays (LCDs), and more particularly, to 3D LCDs for providing stereoscopic images. Background technique [0002] In recent years, as interest in stereoscopic image services has increased, devices for providing stereoscopic images have continued to develop. Among methods for realizing such a stereoscopic image, there is a stereoscopic method. [0003] The basic principle of the stereo method is a scheme in which images arranged perpendicular to each other are input to the left and right eyes of a person in a separate manner, and the image input to the left eye and the image input to the right eye are separately input in the human brain. combined to generate a stereoscopic image. At this time, the images arranged perpendicular to each other indicate that one of the two images does not interfere with each other. [0004] For specific methods for eliminating interference, there are polarization methods...
