The Touch display devices have applied in many fields. Most people pay more attention to its performance configuration and reflect the software applications required during operation; but less people will pay attention to its interface, because applications in different industries will have professional corresponding interfaces. now let's take a look at the different application interfaces of different touch display devices.
As the I/O device of the computer, which is the input and output device, the display 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 for the output of old computers. Both the output and transmission are analog signals. The transmission process is also one time analog conversion and one time analog digital conversion. If the signal is lost, the display is fuzzy.
The digital signal transmitted by DVI interface can transmit large resolution video signal without conversion and signal loss when connecting to computer.
The HDMI interface also transmits digital signals. The video quality is basically the same as that of the DVI interface, but it can also transmit audio.
Three display interfaces are set at the same time, because the display is also one of the adaptive products. The display definition in the market is getting higher and higher, but the early products are not completely eliminated. The display requirements and working environments of different fields are different, so the display interfaces of applications are also different.
Regarding the all-in-one tablet, distinguish between Windows system and Android system. The motherboard architecture is X86 architecture motherboard and ARM architecture motherboard, which determines that the interfaces between the two will be different.
On the Android all-in-one tablet with standard A64 Motherboard, the lower bezel interface is DC, USB, TF/SIM, HDMI/MICRO USB, RJ45, Audio, UBOOT, COM1, COM2; Upper baffle interface: COMX2, WIFI, grounding column.
On the X86 all-in-one tablet with standard CX-J1900 motherboard, the lower panel: DC, VGA, HDMI, USBX2, LAN, audio input, audio output, COMX2; Upper baffle: COMX2, WIFIX2, grounding column.
The difference between the all-in-one tablet and the display is the network connection and external connection interface of the device, RJ45 network interface and LAN interface, and USB interface can be used as the input/output interface (USB2.0 and 3.0 are optional, and the transmission rate is different). The host is integrated with processing and display, while 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. The interface design has an evolutionary process, whether it is power transmission or signal transmission, and tends to be of higher quality and efficiency. Considering the increasingly wide applicability of interfaces, the future interfaces may no longer be biased towards professionalism, and versatility may become its future.
