Because my children have learned about it in online classes, the biggest difference between the Little Genius Eye Protection Tablet and ordinary tablets is its screen. The salesperson said that it is a self-developed nine-layer scattering screen that can absorb the light emitted by the screen. The light reflected from the environment is evenly scattered through this screen, making the light seen by the human eye softer and less dazzling. Personally, I think it is more reliable than ordinary tablets that can adjust the brightness and contrast across the board.
