Infrared receivers for universal infrared 3D TV shutter eyewear unveiled

While the majority of LCD 3D televisions sold today use active shutter glasses to separate the images intended for the left and right eyes and despite efforts to standardise the technology used to synchronize the 3D TVs with their corresponding active shutter glasses, the industry is far from this goal. As a result there exists a large number of incompatible IR and RF protocols from various manufacturers.

The lack of a standard has led to the development of a market for universal 3D TV eyewear capable of functioning with any 3D TV using active eyewear technology.

The TSMP6000 and TSMP77000 integrate a photodiode, amplifier, and signal conditioning IC into a single tiny package reducing the weight of 3D glasses, and their ultra-low current consumption maximises the battery life. The TSMP6000 and TSMP77000 are surface-mount devices that can be mounted in a side or top view. They both have a viewing angle of ± 50°, which allows for significant head movement without signal loss. They have high spectral sensitivity from 800 nm to 950 nm and can receive carrier frequencies from 20 kHz to 60 kHz. The TSMP77000 measures 2.3 mm x 3.0 mm x 6.8 mm and has dual lenses while the TSMP6000 measures 4.0 mm x 5.3 mm x 7.5 mm and has a single lens.

Samples of the new TSMP6000 and TSMP77000 are available now.
