  LCDThe most common places are shopping malls with surveillance cameras that monitor the safe driving of vehicles on the road, as well as high-end buildings and elevators that are equipped with LCD monitors to ensure the safety of internal personnel. If there is a fire or elevator malfunction in some parts of the building, someone on the other end of the monitor will immediately react to solve the problem.

How to choose a better oneLCDWell, to see if the brightness of the screen is uniform, many people will look at the data specification manual, but some things are more subjective when looking at the actual product. The LCD monitor is very bright in the center of the screen, but the brightness decreases by 25% near the edges. So when making a purchase, the best and most effective method is to compare the LCD monitor row by row one-to-one. Once again, I would like to remind readers that data is not the entirety of product performance. The key is whether the brightness is uniform, which cannot be found in the product specification manual. The uniformity of brightness is closely related to the number and configuration of light sources and mirrors, and the brightness will inevitably be darker in places far away from the light source. A high-quality monitor should have a relatively even brightness in its image.

A brighter product does not necessarily mean a better product. If the image is too bright, it can actually reduce the contrast between pure black and pure white. If the brightness of the CRT monitor is set to maximum, the white screen will not show pure black and rich color levels. The situation of LCD displays is not much better, so the brightness and contrast need to be matched perfectly to present a more beautiful picture quality. Choosing a user-friendly LCD monitor is much better than a machine that frequently malfunctions. I believe no one wants to see their product repeatedly have problems. Everyone should consider purchasing oneLCDBe sure to pay attention to the above issues when doing so.
