How to choose a right display – power consumption

Square power consumption is a square meter area of the LED display generated by the power consumption. We usually say that the power unit in KWH, for example, the power consumption of one square meter LED display is 300 watts, and then the display of each square meter per hour will consume 300 KWH of electricity, that is, 0.3 KWH. LED display power consumption generally has two indicators: one is the maximum power consumption, and one is the working consumption. The maximum power consumption is the power consumption when LED display reaches its maximum brightness. Then, how to determine the maximum power consumption merely by eyes?

The method is simple: look at the number of power supply behind the cabinet, multiplied by the maximum power consumption. According to the cabinet size can calculate the maximum power consumption per square meters, generally, using 200W and 300W power supply.

And the working consumption means the consumption of broadcast advertising video, text, picture, because the working consumption has a direct relationship with playback content, it is difficult to have an exact value, but according to our experience, generally it equal to the 1/3 of maximum power consumption Lower power consumption represents lower cost for use and smaller heat, the size of the heat depends on the size of the current, a direct impact on the display life and stability. Energy-saving LED display using 4pcs of 200watt power supply per square meter, so the maximum power consumption will not exceed 680 watts per square meter. Because the effective output for power supply is basically 85%.

How to choose a right display – viewing angle

Refresh rate refers to the number of times the LED display information is displayed every second under a certain brightness and gray scale. 

For outdoor LED display, generally we use the DIP or SMD LED. The DIP LED has small vertical viewing angle and high brightness. The vertical viewing angle of SMD is much larger than the DIP, but its brightness is smaller than the DIP LED. From the user's point of view, the user should be based on the audience viewing side and the surrounding light environment of the LED screen to select a different perspective LED. For indoor LED display because of its low brightness requirements, generally the viewing range is wide, so the SMD LED is the best choice.

 

For reducing the cost, some of the LED manufacturers use the small chips to make the LEDs, but for small chip LEDs, if we need a certain brightness, it has to be a small viewing angle packaging. So in order to have a good rightness, those LEDs may be brightness enough, but the viewing angle might be smaller than regular LEDs. This will lead to a high brightness when the audience are watching from the front side, but an image when the audience are watching from a large viewing angle. Large size chip LED does not require a small viewing angle package, because its brightness is qualified. Therefore, a qualified LED with large chip large angle (normally 110) high brightness and low current is the best.

How to choose a right display – refresh rate

Refresh rate refers to the number of times the LED display information is displayed every second under a certain brightness and gray scale. The refresh rate might be lower when a display goes to lower brightness and higher gray scale. Low refresh frequency leads to fluttering visual phenomenon in human eyes; and scan lines in camera. Usually the qualified refresh rate for human eyes should be more than 300Hz, which is as long as the refresh rate is more than 300Hz, with the naked eye human will not see any fluttering on display. If we use the camera to shoot the display, different camera settings require different refresh rate. Generally, at least more than 600Hz would be qualified to have a video without scan lines. With a digital camera, the refresh rate could be easily detected. if it is with a high refresh, the picture the camera shot will be clear, without snowflake points and scan lines. This is especially important when it comes to rental screens and TV broadcasts displays. Under normal circumstances, the 2000Hz can meet the requirements of high speed camera, such as the perimeter display in stadium. High refresh can improve the brightness and color of the display effect, but not the higher the better, over-high refresh rate like 5000hz means nothing to human eyes and normal TV live and broadcast. With a certain diver IC, the refresh rate is in conflict with gray scale, but PWM diver IC can do better in having both high refresh rate and high gray scale.
