Problems solved by technology

[0004] However, since the stereoscopic display device is in its infancy, an objective standardized system for measuring the optical characteristics of the stereoscopic display device does not yet exist, thereby making it difficult to provide consumers with information on the optical characteristics of the stereoscopic display device
In this regard, 3D video broadcasting and stereoscopic display devices have not been popularized as expected even though there is much attention on stereoscopic display devices as next-generation display devices

Abstract

An optical measuring apparatus and method for a stereoscopic display device are capable of measuring optical characteristics of the stereoscopic display device. The optical measuring apparatus includes a test image supplier for generating a 3D test signal, a 3D display for displaying left-eye image and / or right-eye image based on the 3D test signal supplied from the test image supplier, an image selection member for selectively transmitting the left-eye image and right-eye image to be displayed on the 3D display, and a light measuring device that measures luminance of the image transmitted via the image selection member and calculates 3D image crosstalk of the left eye image and the right eye image based on the measured luminance.

Description

technical field [0001] The present invention relates to a stereoscopic display device, and more particularly to an optical measurement device and method for a stereoscopic display device that facilitates measuring the optical characteristics of the stereoscopic display device. Background technique [0002] This application claims the benefit of Korean Patent Application No. 10-2010-0107234 filed on October 29, 2010, the contents of which are hereby incorporated by reference as if fully set forth herein. [0003] With the practical application of 3D video broadcasting, a stereoscopic display device, as a next-generation display device, has attracted attention in recent years. Therefore, there is an increasing need to measure the optical characteristics of stereoscopic display devices and inform consumers of the superiority of the product. [0004] However, since stereoscopic display devices are in their infancy, an objective standardized system for measuring the optical char...
