The price of LED display receiving cards varies depending on factors such as brand, model, function and market supply and demand, so it is impossible to give a fixed price.
However, I can provide you with some approximate price ranges and detailed introductions based on the current market situation.
Price range
The price of LED display receiving cards ranges from tens of yuan to hundreds of yuan, and there are even higher prices. The specific price depends on the performance, brand, quality and market positioning of the receiving card. Here are some specific examples:
Linxingyu RV908M32 receiving card: The price is about 83 yuan, supports 32 scans, is a kind of LED display control card, and can be used with linsn908 sendable card.
Huidu Technology HD-R708 receiving card: The price is about 63 yuan, full-color LED display receiving card, used for electronic video billboard control.
Colorite 75E synchronous receiving card: The price ranges from tens of yuan to hundreds of yuan, depending on the purchase channel and promotional activities. It is a multi-function control card suitable for indoor and outdoor advertising screens.
NOVA Technology Control Card DH7516S: The price is high, but the performance is excellent. It is a full-color synchronous asynchronous receiving card that also supports the sending function and is suitable for high-end LED displays.
Detailed introduction
The LED display receiving card is a key component in the LED display control system.
It is responsible for receiving image data from the sending card and converting this data into signals suitable for LED screen display. The main functions of the receiving card include:
1. Data reception: Receive image data from the sending card through a network cable or other communication methods.
2. Data processing: Convert the received data according to a specific protocol and format so that the LED screen can display correctly.
3. Signal output: Output the processed signal to the driving circuit of the LED screen to drive the LED lamp beads to emit light.
When choosing an LED display receiving card, the following factors need to be considered:
Resolution and pixel pitch: Determine the carrying capacity of the receiving card (that is, the number of pixels that each receiving card can control) according to the resolution and pixel pitch of the LED screen.
Scanning mode: Static scanning and dynamic scanning have different requirements for receiving cards. Static scanning requires more control signals, while dynamic scanning can reduce the number of control signals through time division multiplexing.
Brand and quality: Receiving cards from well-known brands usually have better performance and longer service life, but the price may also be higher. When choosing, you need to weigh the actual needs and budget.
Functional requirements: Choose receiving cards with synchronous, asynchronous, WiFi, 4G and other functions as needed to meet different application scenarios and needs.
In summary, the price of LED display receiving cards varies depending on many factors, and the specific price needs to be inquired and compared according to the actual situation.
When choosing, you need to consider factors such as resolution, pixel pitch, scanning mode, brand and quality, and functional requirements.
