Abstract: A display device includes an encapsulating structure disposed on an array substrate, a bottom cover accommodating therein the array substrate and the encapsulating structure, and at least one heat dissipation pattern disposed between the encapsulating structure and the bottom cover. The heat dissipation pattern may include a porous framework layer and a heat emission layer composed of particles coated on the framework layer. This heat dissipation pattern may allow heat transfer from the encapsulating structure to the bottom cover to be performed more quickly and efficiently.

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.
