follows the PLM-100 model, which has been discontinued. The PLM-
A55 features a light weight of about 150g, less than half of the
PLM-100's 370g. Sony expects its monthly output will reach 5,000
units.
A magnesium alloy is used for the display part to make it
lighter, and a wire alloy is used for the head-belt, Sony said.
The screen display specifications are the same as for the PLM-
100. It uses two 0.7-in. liquid crystal displays (LCDs) with
180,000 pixels. Sony said that users can experience a virtual
viewing level of a 52-in. screen set two meters in front of the
viewer.
Power source boxes are sold separately. When the NP-F550 for a
lithium-ion battery is attached, the display can play
continuously for up to two hours and 20 minutes, or the same
duration as for the PLM-100. If another power source box (EBP-L7)
for 1.5V batteries is attached, it can play for about two hours
using six alkaline dry cells.
Olympus Optical Co., Ltd. announced a similar type of HMD, called
Eye-Trek, on April 14, and it is slated to ship the device from
June 20.
