摘要： A light waveguide has a rectangular plate shape and is configured to totally reflect internal light arriving at an angle greater than a critical angle. Light emitting parts are disposed at corners of the light waveguide. Each of the light emitting parts emits light once in a period. A first light receiving part is disposed along a first side surface of the light waveguide, and receives light emitted from the light emitting parts adjacent to a second side surface facing the first side surface of the light waveguide. The second light receiving part is disposed along the second side surface of the light waveguide, and receives light emitted from the light emitting parts adjacent to the first side surface. A detecting part detects a touch position based on an amount of the light received by the first and second light receiving parts.

摘要： The present invention relates to a touch module including a light emitting part, a light waveguide, a frustration layer, and a light receiving part. The light emitting part emits light and is disposed along a first direction. The light waveguide includes a first side surface and a second side surface and transmits light incident to the first side surface to the second side surface. The light emitting part is disposed on the first side surface, and the second side surface is disposed opposite to the first side surface along a second direction substantially perpendicular to the first direction. The frustration layer is disposed over the light waveguide and contacts the light waveguide in response to a touch to frustrate a total internal light reflection. The light receiving part is disposed on the second side surface of the light waveguide to detect a position of the touch. The frustration layer includes a plurality of frustration parts, the total internal light reflection is frustrated at a contact surface between a frustration part and the light waveguide, and an area of a first frustration part differs from an area of a second frustration part that is spaced apart from the first frustration part.
