Abstract

The invention discloses an interactive display based on a carbon-based circuit, which comprises a display substrate and a plurality of pixel units positioned on the display substrate, and the carbon-based circuit is arranged between the pixel units and the display substrate. The invention also provides a manufacturing method of the interactive display, which comprises: preparing the carbon nano material film on the display substrate firstly, preparing the carbon-based circuit by using the carbon nano material film as a channel material then, and then preparing the pixel unit on the display substrate with the carbon-based circuit. According to the interactive display based on the carbon-based circuit, non-contact touch of the pixel resolution level can be achieved, the display can activelyconduct detection and active feedback on the outside world, then the display effect is controlled, and in addition, the health condition of a user is monitored through emitted and reflected infrared signals.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a carbon-based circuit-based interactive display and a manufacturing method thereof. Background technique [0002] In addition to the display function, the existing display can also be equipped with some other functions, to a certain extent, realize the real-time control of some pixels of the screen by the external control signal. For example, "touch display" is to control the display state and image through external contact with the screen. At present, this kind of touch display has been widely used in display terminals in many occasions, but the contact touch display screen used in public places usually has hygienic problems such as germ transmission and cross-infection caused by multi-person touch panels. [0003] In addition, existing displays cannot realize signal interaction between different areas inside the screen, and cannot control the display effects of each area at ...
