Embodiment 1

[0037] figure 1 is a schematic diagram of a display detection method of a display device according to an embodiment of the present invention, as shown in figure 1 As shown, the display detection method of the display device in this embodiment includes the following steps:

[0038] Step S1: Obtain the image displayed on the screen collected by the image acquisition device, the image displayed on the screen is generated based on the image detection signal input to the signal source interface of the display device to be detected; the image detection signal is generated based on the standard image.

[0039] For example, in this embodiment, the display device to be detected (such as a television set, a computer display screen or an advertising screen, etc.) is equipped with a plurality of signal source interfaces to be compatible with multiple signals that can be received, for example, ATV (Analog TV, input Analog) signal, AV (audio Audio and Video Video) signal, DP (DisplayPort, ...

Embodiment 2

[0052] figure 2 is a schematic diagram of a display detection system of a display device according to an embodiment of the present invention, such as figure 2 As shown, the display detection system of this embodiment includes a display device to be detected, an image acquisition device, a signal source generation device and a display detection device.

[0053] The display device to be detected is a device capable of displaying various information, such as a TV, a computer display (LCD, liquid crystal display, etc.) The image displayed when the signal source interface receives signals from different information sources is tested for example, image clarity, image contrast, image color, image loss, deformation, etc. Among them, each display device will be equipped with multiple signal source interfaces to be compatible with receiving Various signal sources, for example, at least one of ATV signal, AV signal, DP signal, DTMB signal, DVI signal, HDMI signal, MHL signal, VGA sign...

Abstract

The invention discloses a display detection method, device and system for display equipment. According to the display detection method of the display equipment, the display equipment comprises a signal source interface, the display detection method comprises the following steps that an image, collected by an image collection device, displayed on a screen is obtained, and the image displayed on thescreen is generated on the basis of an image detection signal input into the signal source interface; and the image acquired by the image acquisition device is analyzed to obtain a display detectionresult. The display detection method provided by the invention can be used for replacing workers to detect the display equipment so as to avoid manual detection errors, such as missing detection, wrong detection and the like.

Description

technical field [0001] The present invention relates to the field of equipment detection, in particular to a display detection method, device and system for display equipment. 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] At present, the types of signals that can be displayed by display devices are increasing day by day. Therefore, some display devices, especially liquid crystal display devices such as televisions, usually have more than one signal source interface, which can receive multiple signal sources for display. When the display device has been assembled and is inspected before leaving the factory, workers generally inspect each signal source interface and functio...
