Abstract

The invention provides a method and a display device for processing abnormality of a multimedia signalwith the method comprising: determining whether an abnormality occurs in a multimedia signal received through a multimedia signal input interface of a display device (100); outputting a preset when an abnormality occurs in the received multimedia signal The picture signal is sent to the central processor of the display device, and the central processor outputs the preset picture signal to the display screen of the display device, wherein the preset picture signal includes multimedia signal abnormal prompt information (102). According to the above method, when an abnormality occurs in the received multimedia signal, a picture signal including the abnormality prompt information of the multimedia signal is output to the central processor, and the central processor outputs the picture signal to the display screen of the display device, so as to prevent a screen or bright line from appearing on the screen, and the user may also be prompted to see an abnormality in the multimedia signal.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multimedia signal abnormality processing method and a display device. Background technique [0002] At present, many display devices (such as head-mounted display devices, TVs, computers, tablet computers, etc.) have multimedia signal input interfaces, and the multimedia signal input interfaces can be HDMI (High Definition Multimedia Interface, high-definition multimedia interface, HDMI for short) input interface , DVI (Digital Visual Interface, digital display interface, DVI for short) input interface, etc. Connect external devices (head-mounted display devices, TVs, etc.) through the multimedia signal input interface, and receive and display multimedia signals transmitted by the external devices. The multimedia signals may include video signals, audio and video signals, and the like. When the multimedia signal input interface is in poor contact with the external device, tha...
