Abstract
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.
