Embodiment Construction

[0021] Next, an ideal embodiment of the device for displaying the state of external input according to the present invention will be described in more detail with reference to the accompanying drawings.

[0022] figure 2 It is a schematic diagram showing an explanation of the device for displaying the state of external input according to the present invention.

[0023] refer to figure 2 It can be seen that various external input devices such as VTR, DVD, and set-top box can be connected through the external input receiving device 12 . For example: when the user operates the VTR, the above-mentioned external input receiving device 12 receives the synchronization (SYNC) signal of the VTR.

[0024] The synchronous signal detection device 11 can periodically detect (DETECTING) the received synchronous signal, and confirm the external input terminal that inputs the synchronous signal.

[0025] In addition, when the user wants to confirm the external input terminal that is curr...

Abstract

The invention is related to device in use for displaying external input state. The device is capable of affirming state of external input through OSD image plane, or affirming state of external input of current synchronizing signal, even not affirming the connected terminals. The said device includes: being connected to multiple external input devices, the external input reception device (EIRD) is in use or receiving signal; synchronizing signal detection device (SSDD) in use for detecting the synchronized signal output from EIRD; being located in front of image display device, multiple LED displays are in use for displaying states of external inputs; microcomputer in use for turning on / off multiple LED displays corresponding to the said external inputs based on practical situation of synchronized signal detected by SSDD.

Description

technical field [0001] The present invention relates to a device for displaying the state of an external input. Specifically, it is about being able to confirm the status of the external input one by one through the OSD (On Screen Display) screen, or even if the connection terminal is not confirmed, it is easy to check the external input of the current synchronization signal. A device for displaying the status of an external input for confirmation. Background technique [0002] Currently, various types of televisions are being widely used in a broadcasting environment that provides digital broadcasting. For example: PDP (Plasma Display Panel) TV, LCD (Liquid Crystal Display) TV, projection TV, etc. [0003] Such a TV set can receive various external input signals, and in many cases, it is designed to receive more than 10 external input signals. [0004] As an example of external input, TV sets are generally equipped with COMPONENT (R, G, B), VIDEO (signal, sound; R, L), S...
