Now for the children, parents can spare no expense to buy LED lights, eye-protection LED table lamps and other products, there may be serious stroboscopic! This strobe is caused by the lower refresh rate, the naked eye is not noticeable. However, if used for a long time, it will cause visual fatigue and even headache! In the field test session of the 315 party, the host demonstrated a very simple way to verify the strobe of the LED light, that is, use the camera of the mobile phone to align the light bulb, pay attention to The flashing on the screen of the mobile phone can detect whether the LED light is qualified in one step.
In the same way, the LED display with the same illumination technology, the refresh rate also represents the performance of the product, viewing comfort and shooting effect. When the refresh rate is not enough, the lamp will produce stroboscopic light, which will appear on the LED display screen, which is the water ripple we often say. This is the difference between a good screen and a normal screen. We can take out the mobile phone and use the LED display to shoot a shot against the product. The high and low standing points: the LED display with low refresh rate immediately appears.
In order to shoot the LED display without water ripple, it can be solved by using high-definition high-order PWM driver IC. Up to 3840Hz refresh rate, take pictures of waterless ripples, mobile phone casually shoot, according to the demon mirror to make a strong photo.
At present, Powerful Color has been upgraded to high-definition high-order PWM driver ICs in P3 and below, high-density T-series, standard series (rental), indoor S-series, and A-series. Do LED big screen, find powerful giant color, no water ripple, no LED screen that will flash.
