Abstract
Provided is a touch display device, including: a curved display screen and at least two optical pair transistor groups. The display screen has a curved first edge and a curved second edge. The optical pair transistor group includes a plurality of through-beam units. Each through-beam unit includes an emitter, disposed on an outer side of the first edge, and a receiver, disposed on an outer side of the second edge. A light outlet of the emitter is oriented towards a light inlet of the receiver. The at least two optical pair transistor groups include a first optical pair transistor group and a second optical pair transistor group. An extension direction of a light ray emitted by the through-beam unit in the first optical pair transistor group is intersected with an extension direction of a light ray emitted by the through-beam unit in the second optical pair transistor group.
