Touch display devices are used in many fields. When inquiring about purchasing similar products, most people pay more attention to its performance configuration and reflect the software applications needed during operation; some people also pay attention to its interface, because of different industries. The application will have a professional corresponding interface. Today, let’s take a look at the differences in the application interfaces of different touch display devices.
The interface of touch terminal products depends on the motherboard model.
The monitor is equipped with a JWS2483 model motherboard as standard, and the design interfaces include TOUCH, HDMI, DVI, VGA, audio input, audio output, DC, and it also has expansion interface functions.
As the I/O device of the computer, the monitor can receive the host signal and form an image. The way to receive and output the signal is the interface we want to introduce. Excluding other conventional interfaces, the main interfaces of the monitor are VGA, DVI, and HDMI.
- VGA is mainly used in old-fashioned computer output. The output and transmission are all analog signals. The transmission process is also a digital-to-analog conversion and an analog-to-digital conversion. If the signal is lost, the display will be blurred.
- The digital signals transmitted by the DVI interface can transmit high-resolution video signals, and there is no need for conversion when connecting to a computer, and the signal will not be lost.
- What the HDMI interface transmits is also a digital signal, and the video quality is basically the same as that achieved by the DVI interface transmission, but it can also transmit audio.
Three display interfaces are set at the same time, because the display is also a kind of adaptive product, and the display resolution in the market is getting higher and higher, but the early products are not all eliminated. The display requirements of different fields and the working environment are different, so the display interfaces of the applications are also differentiated.
The difference between the all-in-one machine and the monitor lies in the network connection and the external connection port of the device, the RJ45 network interface and the LAN interface, and the USB interface can be used as the input and output interface (USB2.0, 3.0 is optional, and the transmission rate is different). The host, processing and display are integrated, and the display mainly receives signals and outputs information.
Different fields have different requirements for the functions and expansion of touch display products, which determines the design of the motherboard interface. Interface design has an evolutionary process, whether it is power transmission or signal transmission, it tends to be higher quality and more efficient. Considering that the applicability of the interface is getting wider and wider, the future interface may no longer be biased towards professionalism, and universality may become its future.
