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.

Abstract: Disclosed is a display device including a substrate, a bottom shield metal layer, a driving transistor, and an organic light emitting diode (OLED). The bottom shield metal layer is on the substrate, and is coupled to a voltage source. The driving transistor is above the bottom shield metal layer. The driving transistor includes a first terminal (e.g., a source terminal), and a second terminal (e.g., a drain terminal). The first terminal of the driving transistor is coupled to a reference voltage for setting a voltage value at the first terminal. The coupling of the bottom shield metal layer to the voltage source is independent of the coupling of the first terminal to the reference voltage. The OLED includes an electrode that is coupled to the first terminal of the driving transistor.
