摘要： A light guide plate capable of guiding a light beam from a light emitting device and a backlight module using the light guide plate are provided. The light guide plate includes a light-transmissive substrate and optical structures. The light-transmissive substrate has a first surface, an opposite second surface, and an incident surface connecting the first and the second surface. The light beam enters the light-transmissive substrate through the incident surface and is emitted out of the light-transmissive substrate through the first surface. The optical structures are disposed on the second surface. Each optical structure has a first total internal reflection (TIR) surface, a second TIR surface, and a third TIR surface. The second TIR surface connects the first and third TIR surfaces. Part of the light beam from the incident surface is totally internally reflected by any adjacent two of the first, second, and third TIR surfaces in sequence.

摘要： A touch display apparatus including a display unit, a light confinement element, at least one light emitting device, and at least one optical detector is provided. The light confinement element is disposed beside the display unit, and has first and second total internal reflection (TIR) surfaces, and a light incident surface connecting the first and second TIR surfaces. The light emitting device is disposed beside the light incident surface and capable of emitting a light beam which enters the light confinement element through the light incident surface. The first and second TIR surfaces are capable of repeatedly totally reflecting the light beam in the light confinement element, for confining the light beam between the first and second TIR surfaces. When a touch object contacts the first TIR surface, the TIR effect is spoiled, and the touch object reflects a part of the light beam to the optical detector.
