Visual Stimulus Displays – CRT Replacement

VIEWPixx

New display toolbox optimized for the needs of vision researchers

The VIEWPixx is a complete display toolbox which has been conceived specifically to replace CRTs in vision science labs. The VIEWPixx features high-performance industrial LCD glass and a panel controller designed specifically to support vision research. Our innovative LED backlight design features superior display uniformity, and a wide color gamut exceeding that of any CRT.  The VIEWPixx also includes an array of peripherals which often need to be synchronized to video during an experiment.  The VIEWPixx also includes an array of peripherals which often need to be synchronized to video during an experiment. These include a stereo audio stimulator, a button box port for precise reaction-time measurement, triggers for electrophysiology equipment, and even a complete analog I/O subsystem.

Because we implemented the video controller and peripheral control on the same circuit board, you can now successfully synchronize all of your subject I/O to video refresh with microsecond precision.

As with all VPixx Technologies products, the VIEWPixx is field upgradable. If you need a new feature in order to follow some exciting new direction in your research, we can develop the functionality in our labs, then email you an update for your VIEWPixx.

 

VIEWPixx3D

The VIEWPixx /3D is a complete display toolbox which has been optimized for stereoscopic and other dynamic visual stimuli. The VIEWPixx /3D features LCD glass with the fastest possible pixel response and a panel controller which has been specifically designed for vision research. Our innovative scanning LED backlight design eliminates ghosting, has superior display uniformity and features a wide color gamut exceeding that of any CRT. In addition the VIEWPixx /3D includes an array of peripherals which often need to be synchronized to video during an experiment. These include a stereo audio stimulator, a button box port for precise reaction-time measurement, triggers for electrophysiology equipment, and a complete analog I/O subsystem.

VIEWPixx/ECG

The VIEWPixx /EEG is an affordable high quality display which has been optimized for triggering external data acquisition systems to precisely timed visual stimuli. The VIEWPixx /EEG features LCD glass with the fastest possible pixel response and a panel controller specifically designed for neurophysiology, cognition and psychophysics research. Our innovative scanning LED backlight design eliminates ghosting and has superior display uniformity.  In addition the VIEWPixx /EEG includes 24 TTL output triggers for synchronizing external data acquisition systems such as EEG and eye trackers with microsecond precision.  The triggers can also be used to initiate external stimulators such as TMS.  The levels of the 24 TTL outputs are controlled by the 8-bit RGB components of the display’s top-left pixel.  This strategy is simple to program with any stimulus generation software and guarantees perfect synchronization between video and external hardware.
