- the light shielding structure in the embodiment of the present disclosure has a one-to-one correspondence with the light source in the backlight, and is configured to block the light emitted by the corresponding light source in the backlight, thereby realizing All black mode.
- the liquid crystal molecules in the liquid crystal display are negative liquid crystals
- the long axis of the liquid crystal molecules is parallel to the upper substrate and/or the lower substrate, and there is no potential difference between the first electrode and each electrode unit, so the liquid crystal The liquid crystal molecules in the layer are not deflected, and no lens structure is formed in the liquid crystal layer.
