Brain-Computer Interfaces (BCI) based on the detection of Steady-State Visual Evoked Potentials have proven to be highly efficient. Compared to other BCI paradigm, they usually provide the best information transfer rate. However, this type of BCI requires visual stimuli. These stimuli can be on LEDs or on a computer screen. LEDs can allow flickering lights of high frequencies while flickering lights on an LCD screen can be an integrated as a part of the user interface. We propose a new method for enabling reliable visual stimuli over 20Hz on a classical LCD screen.
