Abstract: A reflection type display apparatus has a front light unit (FLU), and includes a display panel, a light guide disposed on the upper surface of the display panel, a light transparent adhesive layer attaching the lower surface of the light guide to the upper surface of the display panel, and a light source located at a side of the light guide for emitting light to the light guide. A protection window covers the light guide and the light source. By covering the display panel installed on the lower surface of the protection window and the light guide with a moisture-proof and light-shield film, moisture-proofing and light-shielding effects are obtained simultaneously. Further, by forming a light absorption layer at the edge of the light guide adjacent to the light source, generation of a hot spot at the edge of the light guide may be inhibited.

Abstract: A touch screen includes a display screen having an upper surface that provides picture information, and an optical module that emits rays in directions that can be parallel with the upper surface of the screen. When an object, such as a stylus, pen or a finger is placed on the screen to select a portion of the picture information provided on the screen, at least a portion of the rays are reflected off of the object and detected in order to determine a position of the object on the screen. The position of the object can be calculated in various ways including calculating a position of the object based on a phase delay of the reflected rays, or based on an intensity of the reflected rays, or based on an incidence angle of the reflected rays.
