Looking back at the recent years, the TV field seems to have experienced an unforgettable stage of rejuvenation. When the traditional "big-back" TV almost drove the entire television field. The advent of LCD TVs can be said to have brought our country’s television industry back from the edge of the cliff. Nowadays, with increasingly clear picture resolution. Can we transfer this high definition to the monitor ?
We can do a comparison. Under normal circumstances, TVs receive RF signals from TV stations. For this kind of signal size, the general signal is transmitted to about 6 MB, and the TV is clear. The degree is usually also above 400 lines. However, for the monitor, the definition of clarity is more than that required by the television. Therefore, a professional monitor must have a higher bandwidth compensation capability and a higher circuit capacity than a TV set in the transmission channel. The capacity for these expansions is basically that TV does not yet have, so its pursuit of clarity is clearly better than that of ordinary TVs. It also fulfills the task of monitoring some common television functions that are difficult to achieve.
When we select TVs, the degree of clarity and color reproduction is often the two focus issues that we most frequently focus on. For these two problems, if we mainly attribute the influencing factors of the video resolution to the amplitude characteristics of the video channel, the degree of color reduction mainly depends on the phases of the three primary color signals and luminance signals in the monitor. Decided.
Perhaps some friends may ask, in our high-definition television, we observe the color situation has reached a very real level, is it also very different from the monitor? Here, we can still not consider the contrast gap. Just from the point of view of performance and application features, the monitor usually observes images as still images, so the processing power of the monitor color reproduction is higher than that of ordinary televisions. Therefore, on the professional monitor's brightness and color processing, the three primary colors are more accurate than the ordinary home television with more accurate compensation circuit and delay circuit. This ensures that the luminance and chrominance signals are synchronized with the three primary color processing times. This is somewhat wasteful if applied to televisions.
For the current television market, although the old traditional TV has disappeared. But if you want to say that the current LCD TV technology is pure, it still has a big difference compared with traditional TV. In a typical home application, the working time of the television is generally only a few hours a day. And if you use this frequency to monitor, you can use it to describe it.
For a monitor device, its working hours can be calculated in days, and it is even possible to maintain uninterrupted working conditions for more than 306 days a year. Sometimes even in a relatively harsh environment to achieve all-weather work. This requires a higher level of reliability and stability of surveillance cameras.
In addition, compared with ordinary home televisions, the monitor's high requirements in design are still far beyond these. The current, power, temperature, immunity to interference, and electrical shock, as well as the average time to failure, are far greater than those of ordinary TVs. In addition, in terms of pressure resistance, current resistance, temperature and humidity adaptability, etc., the characteristics of the monitor are also higher than those of the television.
At this point, we can see from the performance aging test: Under normal circumstances, a qualified TV set is aged at the time of manufacture, usually at the normal temperature for about 8 hours at the production line; In the high-temperature, high-humidity, and sealed evaluation line, it will take more than 24 hours to test the changes. The gap between these two has apparently been self-evident.
