The Differences between LCD Screen and LED Screen

Most clients always confuse the differences between the LCD screens and LED screens in our daily sales work. Kerchan will give a brief introduction based on the below characteristics.

First of all, the application place of  LCD Screen and LED Screen: 

The key factor for indoor and outdoor applications is the changeability of light. Eyes are very sensitive to brightness. Due to the weak light indoors, the brightness of the screen should be lower. According to the International standard, the brightness of more than 700cd/ ㎡ will harm the eyes. While owing to the strong sunshine in the open air, only the high brightness of the screen can present the image clearly which can be seen by people.

The best eye viewing effect can be achieved by the LCD screen brightness from 450 cd to 700 cd with uniform brightness and colour saturation. 

With intense brightness, the image on the LED screen is still clear even though the sun illuminates directly. It can adjust the screen brightness function automatically to obtain a good play effect in the different illumination environments. So it can be used indoors and outdoor. But with the self-luminous display technology, the screen brightness of the LED screens is generally very high. If you want to control the brightness to conform to human eyes for the best viewing effect, an LCD screen is the better choice.

Secondly, the LCD screen is better than the LED screen in the features of lifetime, response time, and power consumption. 

Except that, the view angle of the LCD screen is over 178 degrees with the image vertical adjustment technology, wider than the LED screen.

Every coin has two sides. Therefore, when to choose an LCD screen or LED screen is depending on the application environment and product quality of the manufacturers.
