AI Technical Summary
In current LCD displays, dynamic dimming technology makes it difficult to efficiently and accurately detect and adjust backlight brightness to avoid screen burn-in, while expensive brightness detection equipment increases detection costs.
The estimated peak brightness of the target image is obtained and input into the peak brightness fitting model for correction. The peak brightness of the display device is automatically detected by the software algorithm, and the estimated peak brightness is determined by combining the backlight matrix and diffusion matrix. The model is then corrected using machine learning models such as neural networks.
It enables automatic detection of peak brightness of display devices, improving detection efficiency, reducing costs, and ensuring detection accuracy without the need for expensive brightness detection instruments.
