Differenza 1: nitidezza dell'immagine
Commercial liquid crystal display products (LCD advertising machine, touch all-in-one machine) have the function of intuitively reflecting the image quality, in addition to the full 19201080/38402160 resolution. For the selection of display equipment in the field of broadcasting and television, the liquid crystal display is the preferred display. , The resolution of professional monitors is automatically adjusted according to the display output (regardless of whether it can be supported horizontally and vertically); its high reliability and high-definition display capability will ensure that you can record and edit the high-definition audiovisual and video signals in complete display. In front of him. Ordinary display devices only support several common TV resolutions specified in the manual for effect processing, and special resolutions will cause screen blurring.
La seconda differenza: pannello LCD
Regardless of the TFT liquid crystal panels used in commercial and civilian displays, the differences between them are mainly manifested in the size of liquid crystal molecules, imaging processing and color, brightness and contrast, and viewing angles.
Le molecole di cristalli liquidi che compongono un normale display a cristalli liquidi sono più grandi di quelle di un display commerciale, perché la distanza di visualizzazione di un display commerciale non è generalmente superiore a 1 metro. La cosa più importante è mostrare i dettagli, quindi le molecole di cristalli liquidi che lo compongono sono ovviamente più piccole. Il costo del pannello è anche più costoso. I normali display a cristalli liquidi vengono utilizzati principalmente per rappresentare l'intero schermo e non richiedono molto piccole parti. Ancora più importante, l'uso di cristalli liquidi-di grandi molecole può ridurre i costi.
Differenza 3: Stabilità
Commercial liquid crystal display products usually need to operate 24 hours a day to meet the needs of displaying various information, and the environment is much harsher than that of civilian display equipment, which places higher requirements on product performance.
Compared with ordinary display devices, in terms of design, the current, power consumption, temperature, and resistance to electrical interference, electrical shock, and margin of commercial displays, as well as the average barrier-free use time, are far greater than the former. At the same time, commercial displays must use a fully shielded metal shell to ensure electromagnetic compatibility and interference performance. In the selection of components, the components used in commercial displays have higher withstand voltage, current, temperature, humidity and other characteristics than TV sets. Components used.
In addition, the requirements for installation and debugging, especially the process requirements of components and the aging of the whole machine, are also higher. When ordinary display equipment is manufactured, the aging of the whole machine is usually about 8 hours when the assembly line is energized at room temperature, while the aging of the whole machine of the commercial display needs to be energized and aged for more than 24 hours on the aging streamline in a closed environment with high temperature and high humidity to ensure the whole machine The stability.
Differenza quattro: interfaccia
Because of the connection requirements, commercial LCD products (LCD advertising machines, touch all-in-ones) generally customize motherboards and software according to user needs, and do diversified development according to user scenarios and application functional requirements. One-to-one implementation of firmware, Rewriting of software functions; not standardized TV products.
