4.2 Resolution

The resolution of a display determines the sharpness of the virtual image seen by the viewer (Figure 7). Resolution is determined by the combination of the FOV and the pixel density of the display. A typical human eye resolves about 1 arcminute per pixel. That means that a person with 20/20 vision can resolve a maximum of 60 pixels in a 1° FOV. A WVGA (854 x 480) resolution DLP chipset enables up to a 14° HFOV in which the viewer will be unable to discern the individual pixels in the virtual image.
