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.

摘要： A light guide plate has a bottom surface including flat surfaces (FSs) and a plurality of prism patterns (PPs) disposed alternately with the FSs, a light emitting surface (LES) and a light incident surface (LIS). Each FS is at a first distance respectively from the LES and the first distances gradually decrease along a direction away from the LIS. Each PP has a first slanted surface (FSS) and at least a groove having a second slanted surface (SSS) and a third slanted surface (TSS). The two opposite sides of the FSS are spaced out a second distance apart. The two opposite sides of the SSS are spaced out a third distance apart. The specific value of dividing a first orthogonal projection of the second distance on an axis perpendicular to the FSs by a second orthogonal projection of the third distance on the axis is between 0.5 and 1.5.
