Problems solved by technology

[0002] The display screen is generally used to display text, pictures and other information, which is convenient for users to read information. Conventional display screens mainly rely on changing the brightness of the screen to facilitate users. Generally, the light transmittance cannot be adjusted. However, this will increase the power consumption of the screen.
