What is the difference between an industrial display and an ordinary liquid crystal display? They look the same in appearance, but the industrial display is obviously more advantageous in terms of image and stability. Next, the Flat Panel Display Factory will take you to see its specific differences.
First, the overall stability (including the use time, anti-interference, etc.)
When a monitor constitutes a closed-circuit monitoring system, it usually requires 24 hours a day, 365 days a year without interruption (and the TV usually only works a few hours a day), and the application environment of some monitors may be harsh, which requires the monitor Higher reliability and stability. Compared with televisions, in design, the current, power consumption, temperature and resistance to electrical interference, the ability and margin of electrical shock, and the average time between failures of the display are much larger than those of the TV. At the same time, the display must also use full The shielded metal casing ensures electromagnetic compatibility and interference performance; in the selection of components, the components used in the display have higher voltage, current, temperature, humidity and other characteristics than the components used in televisions; Debugging, especially the process requirements of components and the aging of the whole machine, the requirements of the display are also higher. The aging of the whole machine when the TV is manufactured is usually energized for about 8 hours at normal temperature on the assembly line. The high-humidity sealed environment aging line is energized for more than 24 hours to ensure the stability of the whole machine.
Second, the use of machine materials
Due to the requirements of the use environment, the material portion of the Industrial Display housing is metallic. And the internal board and line are all industrialized design, not easy to age; the embodiment of energy saving and environmental protection concept: low energy consumption design; environmental protection materials use. The structured appearance is convenient for industrial needs such as splicing and combination installation.
In contrast, the entire LCD TV housing is designed with non-metallic materials. The internal board line is designed for civilian use, and prolonged startup will easily cause aging of the parts. In addition, the appearance of civilian televisions is mostly irregular, with sound systems and external arc systems as auxiliary facilities for hearing and vision. The overall appearance and effect of construction will be greatly reduced.
Third, the degree of color reproduction
If the definition is mainly determined by the amplitude-frequency characteristics of the video channel, the degree of reduction is mainly determined by the phase of the chrominance and luminance signals of the three primary colors of red (R), green (G), and blue (B) in the display. Decide. Because the monitor usually observes static images, the color reproduction of the display is higher than that of the television. Therefore, the display channel of the professional display should have accurate compensation in brightness, chroma processing and R, G, and B processing. Circuit and delay circuit to ensure that the phase of the bright / color signal and R, G, B signal are synchronized.
On the contrary, due to the requirements of the use environment of the LCD TV, the image is displayed after being polished. It cannot completely reflect the actual effect.
Fourth, the port
LCD displays mostly use industrial ports such as the RGB BNC color difference belt self-locking interface and professional DVI-D video interface; on the other hand, LCD TVs do not have BNC self-locking color difference input interfaces and DVI-D interfaces.
According to the above points, we can know that the differences between industrial displays and ordinary LCD displays vary from the materials used, stability, and color reproduction. The above is the detailed introduction of the Industrial Touch Panel PC supplier. Hope to help everyone.
