Outdoor full-color led display appears inconsistent brightness? Point-by-point correction can help you solve it! Let’s take a look at it:
Principle of calibration:
Point-by-point correction is a technique for uniform brightness and color fidelity of the led display screen. Each pixel data is collected by the relevant device, and the feedback system is processed to reduce the difference. This technology allows different batches of products to be stitched together to make the picture look natural.
The calibration technology is divided into single box and field correction, which are suitable for the correction of small screen and large screen respectively. In addition, it is divided into brightness correction and chromaticity correction. The brightness correction can adjust the intensity of the illumination, and the chromaticity correction can accurately measure the brightness and chromaticity of the LED. In different batches of led screens with the same dominant wavelength, it is necessary to adjust the brightness and chromaticity, which can ensure the brightness and the color effect.
The most important thing is that for the tail-end products, the price stands an absolute advantage. Through the point-by-point correction, it is not only different from the first-product display, but also has a favorable price, and also improves the use value of the LED display products.
