Nov 5, 2000: APEC announces new shutterglasses model
Here's what APEC says:
" WD05 is the first LCS glasses which is capable of blocking the incident image completely even in a circumstance that the installation angle of LCS is as large as 20 degree. For any existing LCS, the leakage, which results in part of the ghosting
image, becomes severe when the installation angle of LCS is larger than 7 degree. This is the reason why the current 3D glasses always looks flat. With the capability of large installation angle, the design of WD05 is extremely slim and cool."
