Embodiment Construction
[0018] First, the definitions of two technical terms are given.
[0019] The "viewing angle" refers to the angle formed by the line of sight of the human eye and the vertical direction of the display surface.
[0020] "Exit angle of light" refers to the angle formed by the light emitted by a light-emitting element, such as a light-emitting diode, and the vertical direction of the display surface.
[0021] As mentioned in the background art, the brightness of common display products with anti-privacy function (hereinafter referred to as anti-privacy display products) is relatively low. Specifically, common anti-peep display products are usually realized based on the principle of shutters, that is, the light emitted by the light-emitting element is blocked when it hits the blades of the shutter, and can pass through when it hits the gap between the blades, so as to realize display with a narrow viewing angle. , so as to realize the privacy protection function. The shaded part ...
