The LCD Shutter Panel is a electronic unit including 2 LCD high speed shutter panels. The electronic control generates an internal 120 Hz synchronization signal and a square wave with 0V DC offset, which is output to the 2 LCD shutter panels. This 120 Hz signal is permanently available as an output from the electronic control and is available as a TTL square wave with a duty cycle of 50% for the synchronisation of other electronic devices. This signal can be directly connected to the next LCD electronic control in order to daisy chain several devices.
When an external sync is detected the internal 120 Hz is disabled and the sync output is still available but at the frequency of the external sync.
The projection screen can be any white screen. There is no need for a special silver coated screen which is needed for polarization projection solutions.
The LCD Shutter Panel is available as a OEM system without projectors or as a turnkey solution including projectors, ceiling mount and installation.
The LCD shutter panel system consists of the following:
- 2 x LCD shutter panels
- 1 x Electronic control box
- Connection cables
- External power supply
