Abstract
Official abstract text for this publication.
The present invention discloses shutter glasses and a 3D display system. The shutter glasses include a first polarizer, a second polarizer, a normally-white LCD panel, and a normally-black LCD panel. A thickness of the normally-white LCD panel is not the same as a thickness of the normally-black LCD panel, and an optical compensation film is installed between the first polarizer and the liquid crystal layer of the normally-black LCD panel and/or between the second polarizer and the liquid crystal layer of the normally-black LCD panel in order to compensate for a dispersion occurred when the liquid crystal layer of the normally-black LCD panel is in a dark mode. In this way, the present invention can not only shorten the response time of the shutter glasses to reduce the power consumption, but also reduce the 3D crosstalk.
First claim
Opening claim text (preview).
What is claimed is: 1. A shutter glasses, comprising: a frame; a liquid crystal display panel, installed inside the frame, the liquid crystal panel comprising stacked a normally-white LCD panel and a normally-black LCD panel, wherein a thickness of the normally-white LCD panel is not the same as a thickness of the normally-black LCD panel; a first polarizer, installed between the normally-white LCD panel and the normally-black LCD panel; and a second polarizer; wherein the…
