Abstract: A virtual reality display device that can include a first pixel array and a second pixel array. Pixels of the pixel arrays can have a response time that is less than 2 msec, where the response time for a pixel is a sum of a first amount of time for brightness of the pixel to rise from 10% of white luminance to 90% of white luminance and a second amount of time for response time to fall from 90% of white luminance to 10% of white luminance. Additionally, the first pixel array can be separated from the second pixel array by a gap, and a distance from a center of the first pixel array to a center of the second pixel array is between 58 mm to 72 mm.
