To buy a stage rental LED display, please choose a high refresh rate LED screen
Before buying an LED display, you should know the proper nouns and parameters, such as brightness, contrast, refresh rate, current, driver chip, IP56, etc.,
If you want to buy stage rental LED screen. The refresh rate is very important, so what is the relationship between the refresh rate and the LED display?
In fact, the refresh rate is the number of times the screen is refreshed per second. Each display video is actually a pair of still pictures, which has nothing to do with slideshows.
The reason why we can feel that this is a continuous motion picture is because the producer uses the visual stop effect of the human eye itself, and the previous picture stays in the picture.
The impression in the brain has not disappeared, and the next picture will follow, and the difference between the two pictures is very small, and an action needs to be displayed by many pictures.
The screen replacement frequency is what we call the refresh rate.
The refresh rate, the rate at which the LED display is updated, is usually expressed in Hertz (Hz).
When the refresh rate of the LED display is higher than 1000Hz, the human eye cannot distinguish it. When the refresh frequency is above 3,000Hz, it is a high-efficiency LED display.
display screen. The higher the refresh rate, the more stable the screen display will be and the smoother the video playback will be. And when recording or photographing, the screen display will be clearer without flicker or water.
Wave fringes and other phenomena exist.
When the "refresh rate" of the LED display screen is low, in addition to the occurrence of water stripes during photography and photography, it will also cause tens of thousands of bulbs to flicker at the same time.
When viewing the images, the human eye may feel uncomfortable, or even cause damage to the eyes.
The refresh rate is due to the different choices of driver chips. When using a common driver chip, the full-color refresh rate is 960Hz, and when using a dual-latch driver chip, the refresh rate is above 1920Hz. When using a high-definition high-end PWM driver chip, the refresh rate is as high as 3840Hz or more or 7680Hz.
ASRAM's existing LED products use high-definition high-end PWM driver chips, with a refresh rate of ≥3840Hz, and the screen display is stable and smooth, without ripples, freezes, and blindness.
Feel the flickering feeling, not only can you enjoy the high-quality LED screen picture, but also effectively protect your eyesight, you can watch as long as you want, and your eyes are not tired at all!
