Abstract:
A corner cut liquid crystal display (LCD) device including a LCD panel and a backlight. The LCD panel includes adjacent panel portions of different width that collectively define a corner cut profile shape for the LCD panel. The backlight includes a light guide and light sources that emit light into the light guide. The backlight directs the light from the light sources toward the LCD panel. The light guide includes adjacent light guide portions of different width that define the corner cut profile shape. Each light guide portion illuminates a corresponding LCD panel portion. The LCD device can be incorporated into a head-mounted display (HMD). The corner cut profile shapes of two adjacent LCD devices, one for the left eye and one for the right eye, may define an open region for placement of other components or parts of the user, such as the user's nose when wearing the HMD.
