Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display device and a signal source detection method in the display device. Background technique [0002] Display devices are used to display various information, and are widely used in office, teaching, entertainment, business presentations, etc. Existing display devices include cathode ray tube (CRT) displays, liquid crystal displays (LCD), light emitting diode (LED) displays, plasma displays (PDP), projectors, and other types. [0003] At present, the types of video signals that can be displayed by display devices are increasing day by day. Therefore, some display devices, especially large-screen display devices such as projectors, usually have more than one signal source interface, which can receive different types of video from multiple signal source devices. The signal is displayed. Taking a projector as an example, it usually has the following types of s...
