There are many brands TFT LCD display on market, are you curious about how to choose? You refer to follow parameters:
1. Brightness: Brightness is an important indicator of the LCD display. The low brightness caused by technical reasons will directly affect the visual experience of the LCD display, let alone the experience. The indicator of brightness is usually expressed in cd/m2. The image performance that can be obtained by a liquid crystal display reaching 200cd/m2 may already surpass that of a traditional CRT display. Of course, the higher the brightness indicator, the higher the display contrast, and the color of the picture. The brighter and brighter it is, the brightness of the current mainstream 15-inch LCD monitors is mostly 200~350cd/m2. Technically speaking, LCD brightness and its uniformity are related to the number, brightness and arrangement of backlight tubes.
2. Contrast: because the contrast is difficult to measure accurately by the instrument, it often becomes one of the more controversial indicators. But one thing is the consensus of the industry - greater contrast is not better, and it must be matched with brightness to create beautiful colors. Only a suitable contrast ratio can make the liquid crystal display the ideal gray scale and color scale, so as to realize the full and rich image effect.
3. View angle: This indicator defines the range of the picture that can be viewed. If the viewing angle is relatively small and the user's line of sight is slightly off (that is to say, it is not facing the screen), because the brightness of the picture outside the viewing angle area is weak, the display picture cannot be seen clearly or even at all.
4. Response time: This indicator determines the performance of the LCD display for fast moving pictures. The short response time will result in a clean picture, and the long response time may lead to afterimages, tailing and other phenomena, especially when playing fast pictures. When the time is too long, a 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 LCD monitors. While still incomparable to CRT monitors, there is no longer any noticeable smearing when watching DVDs and playing most games. For this indicator, it should be noted that many manufacturers use the half-time response time instead of the full-time method.
5. Appearance: the reason why the LCD screen has attracted the attention and favor of consumers is that in addition to its own characteristics such as no radiation, the novel shape design and the fact that it does not take up too much space are its highlights. When choosing a style you like.
