Abstract

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.

Dependent claims

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 normally-black LCD panel comprises a first substrate and a second substrate, a liquid crystal layer of the normally-black LCD panel is sandwiched between the first substrate and the second substrate, the first substrate is close to the first polarizer, the second substrate is close to the second polarizer, and the optical compensation film is installed between the first substrate and the first polarizer and/or between the second substrate and the second polarizer in order to compensate for a dispersion occurred when the liquid crystal layer of the normally-black LCD panel is in a dark mode,
wherein a thickness of the optical compensation film is determined according to a variance trend of the dispersion of the liquid crystal layer of the normally-black LCD panel, and the thickness is determined to be thicker when the variance trend is larger.
