Excuse me, what is the difference between the matrix backlight LED of Skyworth flat-panel TV and the healthy full-screen TV?

Healthy full-screen scene change and photosensitive scene change edge adjust the clarity and layering of image quality according to the strength of signal source. Photosensitive screen changing is an external photosensitive technology, which can be combined internally according to the brightness of indoor brightness level TV screen to save energy and protect eyes.
