One, clarity
For definition resolution, it is undoubtedly one of the most important aspects of our choice of LED display. Devices with higher resolutions naturally receive more attention. Dejian Optoelectronic recommends that before buying equipment, we must select the resolution distribution according to our needs.
Second, the degree of color reproduction
Friends who are familiar with security know that color reproduction is an indispensable and important function in ensuring high-definition surveillance.
Third, the degree of gray demand
The gray scale on both sides of the resolution card is actually an important tool to respond to color reproduction. For this part of the link, we can better grasp the LED display display device for detailed identification of the color of some objects with less differences, so as to more fully grasp the working conditions of the device.
Fourth, the distinction of contrast
For display devices, the higher the contrast, the stronger the image layering. Today, the large LED display on the market can achieve a contrast ratio of more than 1000:1.
Fifth, the viewing angle can not be ignored
The viewing angle as a part of the security industry's LED large screen will affect the image viewing effect, and even create blind spots for visual viewing.
