摘要： A backlight assembly includes a light guide plate (100), containing a plurality of dots (110). Each dot (110) includes a first reflecting surface (111) and a second reflecting surface (112), respectively configured to reflect a first incident light such that reflected light emerges in a first preset direction in a narrow viewing angle mode, and to diffusely reflect a second incident light such that the reflected light emerges dispersedly in a wide viewing angle mode. A first light source(201) can be disposed over a lateral side of the light guide plate (100) and facing the first reflecting surface (111), to provide the first incident light on the first reflecting surface (111) in the narrow viewing angle mode. A second light source (202) can be disposed over another lateral side of the light guide plate (100) and facing the second reflecting surface (112) to provide the second incident light on the second reflecting surface (112) in the wide viewing angle mode.

摘要： A visual range adjustment component and a driving method thereof, a visual range adjustment device, and a display device are disclosed. The visual range adjustment component includes a first substrate (110); a second substrate (120); an electrolyte layer (130); and a plurality of electrochromic elements (200). Each of the plurality of electrochromic elements (200) includes a first transparent electrode (140), two second transparent electrodes (150) and an electrochromic layer (170); the first transparent electrode (140) is located on a side of the first substrate (110) facing the second substrate (120), and the second transparent electrode (150) is located on a side of the second substrate (120) facing the first substrate (110); the electrolyte layer (130) is arranged to be in contact with the first transparent electrode (140), the second transparent electrode (150), and the electrochromic layer (170), respectively; the first transparent electrode (140) and the two second transparent electrodes (150) respectively drive the electrochromic layer (170) to change color through the electrolyte layer (130) to adjust a visual range.
