There are many types of LED display video cables, which are mainly used to transmit video signals to ensure that the LED display can display images normally.
The following are some common types of LED display video cables and their detailed introduction:
I. AV cable (RCA cable)
* Definition: AV cable is a cable used to transmit analog video signals, also known as RCA cable.
* Features: It usually consists of three wires, namely red, white and yellow plugs, corresponding to the right channel, left channel and video signal respectively. The resolution of AV cable is low and the image quality is relatively poor, but it has high reliability and stability.
* Application scenario: It is still widely used in some occasions where image quality and delay are not required.
II. S-Video cable (S terminal cable or Y/C cable)
* Definition: S-Video cable is an analog video signal transmission cable.
* Features: Transmitting the brightness signal (Y) and the chrominance signal (C) separately helps to improve image clarity, especially in scenes with bright colors and high contrast. But it performs generally in terms of transmission distance and anti-interference ability.
* Application scenarios: Suitable for occasions with certain requirements for image clarity.
III. VGA cable
* Definition: VGA cable is a special cable used to connect the VGA interface of a TV or monitor and the VGA interface of a graphics card.
* Features: The VGA interface is a D-type interface with a total of 15 pinholes, divided into three rows, five in each row. This interface design makes the VGA cable have better stability and compatibility when connected.
* Application scenarios: Widely used in various computer display devices and projectors and other devices, especially when connecting old devices or performing basic projection displays.
IV. DVI cable
* Definition: DVI cable is a digital video interface cable.
* Features: Mainly used to connect computer monitors, projectors and other devices to transmit digital signals to ensure image quality and stability. It has the advantages of fast speed, clear picture, stable signal and wide applicability.
* Application scenarios: In some occasions that require higher resolution and refresh rate, such as professional graphic design, e-sports games, etc., DVI cable is a good choice.
V. HDMI cable
* Definition: HDMI cable is the abbreviation of high-definition multimedia interface cable.
* Features: It can transmit uncompressed high-definition video and multi-channel audio data with high quality, without the need for digital/analog or analog/digital conversion before signal transmission, ensuring the highest quality audio and video signal transmission.
It has the advantages of high-quality transmission, long-distance transmission, high bandwidth, ease of use, intelligence and wide compatibility.
* Application scenarios: It is widely used in home theaters, game entertainment and other occasions that require high-definition display.
VI. DisplayPort (DP cable)
* Definition: DisplayPort is a high-definition digital display interface standard.
* Features: It supports simultaneous transmission of video and audio, with higher bandwidth and higher resolution support capabilities.
It has the advantages of high bandwidth, high resolution and high refresh rate support, multi-screen output, good stability and good compatibility.
* Application scenarios: It is suitable for occasions that require high-performance display and transmission effects, such as professional graphics processing, multimedia production, etc.
VII. Other specific types of cables
* IDC cables, LVDS cables, etc.: These cables are also common in the internal connections of LED displays and are used for data transmission and signal connections. They are flat and thin, making them easy to wire inside the display.
Purchase suggestions
1. Clarify your needs: Choose a suitable video cable based on the resolution, refresh rate, and other requirements of the LED display.
2. Consider the transmission distance: Signal attenuation and interference issues need to be considered during long-distance transmission.
3. Pay attention to cable quality: Choose a cable brand with reliable quality and stable performance.
4. Refer to user reviews: Understand other users' reviews and professional reviews to make a more informed choice.
In summary, there are many types of LED display video cables, and each cable has its own unique characteristics and application scenarios.
When purchasing, you need to choose according to actual needs to ensure the normal operation and optimal display effect of the LED display.
