Abstract

The invention discloses a display equipment detection method, device and system, the display equipment comprises a signal source interface, and the detection method comprises image detection and sounddetection; the image detection comprises the following steps: acquiring an image displayed on a screen collected by an image collection device, wherein the image displayed on the screen is generatedbased on an image detection signal; analyzing the image acquired by the image acquisition device to obtain a display detection result; the sound detection comprises the following steps: obtaining an audio output by the display equipment and collected by an audio collection device, wherein the audio output by the display equipment is generated based on an audio detection signal; analyzing the audiocollected by the audio collection device to obtain a sound detection result; wherein the image detection signal and the audio detection signal are respectively input into the signal source interface,or the image detection signal and the audio detection signal are contained in a video detection signal input into the signal source interface.

Description

technical field [0001] The invention relates to the field of equipment detection, in particular to a detection method, device and system for a 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) and other types. [0003] However, the existing display devices can not only display images on the screen, but also play sounds at the same time, and the types of signal sources input to the display devices are increasing day by day. For example, LCD screen display devices such as TVs can receive various image signals, audio signals Or a signal source such as a video signal. When the display device has been assembled, the quality inspection before leaving the factory is generally carried out by ...
