There are many brands of LCD screens on the market, and there are various styles, so you will inevitably encounter some difficulties when choosing. Next, the editor will show you a simple and easy-to-understand method when choosing an LCD screen.
1. Look at the brightness: brightness is an important indicator of liquid crystal displays. The low brightness caused by technical reasons will directly affect the visual experience of liquid crystal displays, and the experience is even more difficult to talk about. The brightness index is usually expressed in cd/m2, and the image performance that can be obtained by a liquid crystal display up to 200cd/m2 may already surpass traditional CRT monitors. Of course, the higher the brightness index, the higher the display contrast, and the color of the screen. The brighter and brighter the current mainstream 15-inch LCD monitors are, the brightness is mostly 200350cd/m2. Technically speaking, the brightness and uniformity of liquid crystal displays are related to the number, brightness and arrangement of the backlight tubes.
2. Look at contrast: Because contrast is difficult to accurately measure with instruments, it often becomes one of the most controversial indicators. But one thing is the consensus of the industry-the greater the contrast is not the better, it must be matched with the brightness to create beautiful colors. Only an appropriate contrast can make the LCD display ideal gray scale and color scale, so as to achieve a full and rich image effect.
3. Look at the viewing angle: This indicator defines the range of the screen that can be viewed. If the viewing angle is relatively small, and the user's line of sight is slightly biased (that is, not directly facing the screen), the display screen cannot be seen clearly, or even cannot be viewed at all, because the brightness of the screen outside the viewable area is weak.
4. Look at the response time: This indicator determines the performance of the liquid crystal display for fast moving pictures. Short response time will result in a clean picture. Long response time may lead to afterimages and tailing of the display, especially when playing fast pictures. When the time is too long, the delay will inevitably occur, which has become a major obstacle to enjoying DVDs and playing games. The indicator unit of this technology is ms, and 25ms has become the standard response time of most liquid crystal displays. Although it is still incomparable with CRT monitors, there is no longer any obvious tailing phenomenon when watching DVDs and playing most games. For this indicator, it should be noted that many manufacturers use half-process response time instead of full-process time.
5. Look at the appearance: The reason why liquid crystal displays have attracted the attention and favor of consumers is that in addition to their own characteristics such as non-radiation, the novel shape design and not taking up too much space are the highlights. When choosing the style you like.
These are some very intuitive things, we can experience directly through vision. If we can't meet these basic conditions, the other parameters will be useless no matter how good. Therefore, it is important to look at several parameters when choosing the LCD screen.
