    Abstract: A method and device for modulating a brightness-grayscale curve of a display device are provided. The method includes determining an applicable standard brightness-grayscale curve for eye perception; obtaining theoretical brightness values corresponding to respective grayscales of the display device based on the applicable standard brightness-grayscale curve for eye perception and at least one of an eye pupil change factor, an environmental factor and a factor related to the display device; modulating brightnesses of the display device according to the theoretical brightness values corresponding to the respective grayscales of the display device. The above method is a solution to the problems of low grayscale details, backlighting, high grayscale saturation, and transition-color unevenness. The problem is solved that a visible grayscale in a dimmed session is no longer distinguishable in a bright environment. And a quantifiable standard for modulation control is provided.

    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.
