Abstract: A display includes a display area that emits light and a border region surrounding at least a portion of the light emitting region. A light guide plate is overlaying the display area. A lighting module is operatively interconnected with the light guide plate to provide light to the light guide plate and positioned within the border region, and a one camera module is operatively interconnected with the light guide plate to sense light from the light guide plate and positioned within the border region. The display determines a position of a touch on the light guide plate by determining a location of frustrated total internal reflection within the light guide plate as a result of the touch on the light guide plate.

Abstract: Aspects of the present invention are related to systems, methods and apparatus for determining the orientation of a text line or a page in a document image. According to a first aspect of the present invention, an image of text blobs may be generated from a text mask associated with a document image. From the text-blob image, pixel-wise horizontal differences may be accumulated and compared to accumulated pixel-wise vertical differences. Text line orientation may be determined as horizontal when the accumulated pixel-wise horizontal differences are less than the accumulated pixel-wise vertical differences. According to a second aspect of the present invention, page orientation may be determined by reconciling an estimated text-line orientation with document language information.
