Abstract
The present disclosure provides a smoke detecting circuit and a display panel using the smoke detecting circuit. The circuit includes a smoke sensor, a smoke detecting module, and a first switch module. When the circuit is triggered on fire or smoking because of a short circuit, the smoke sensor is able to detect a smoke signal, the smoke detecting module is able to export a controlling signal immediately to control disconnection of the first switch module, cutting off a power source of a load, and protecting the load immediately while an accident happens. The load can be a display panel. The smoke detecting circuit is used for detecting the smoke signal of the display panel, without any additional external multi-function card, which reduces the installation space of the display panel with an easier arrangement of flat cables, and protects the display panel right away from accidents.
