As we all know, the quality of the core components of the LED display will directly affect the display effect of the screen. For example, power supply, driver chip, LED lamp beads, etc.
Chainzone contains other products and information you need, so please check it out.
For the refresh rate and gray scale of the LED display, the LED driver chip directly determines the visual performance of the display.
Among the current LED driver chips, the latest technology is &#;ScrambledPWM (S-PWM) technology&#;.
If you want to learn more, please visit our website vms led display.
S-PWM technology is a technology that improves the traditional pulse width modulation (PWM). into several shorter on-times to increase the overall visual update rate.
The LED display screen of the S-PWM driver chip is photographed with a high-speed shutter of a digital camera, and there will still be no horizontal black scanning lines and color block distribution.
Its visual refresh rate and grayscale performance are far superior to LED displays using traditional switch-type driver chips.
