Abstract
An overlay panel that includes a front display portion arranged over surface area of a display device. The overlay panel further includes a guiding portion that comprises light guides arranged in a specific pattern. The light guides are arranged such that an input portion of each light guide is aligned with pixels or sub-pixels of the display device and an output portion of each light guide is coupled to the front display portion. The arrangement of each light guide transfers an excitation, caused by the set of pixels or sub-pixels, from the input portion to the output portion and causes the front display portion to display an image that covers a bezel portion and the display portion of the display device. Each pixel in the image is scaled by an equal scaling factor with respect to each pixel in display portion.
