Embodiment Construction

[0033] figure 1 A schematic diagram of an optical accessory disposed on a display surface of a display device according to an embodiment of the present invention. Please refer to figure 1 . This embodiment provides an optical accessory 100 for being disposed on the display surface S of the display device 10 . The optical accessory 100 is, for example, directly fabricated on the display surface S of the display device 10 , or detachably disposed on the display device 10 , but the present invention is not limited thereto. For example, the optical accessory 100 may be a screen hanger mounted on the display device 10 to cover the display surface S. As shown in FIG.

[0034] In detail, in this embodiment, the optical accessory 100 includes an optical film stack 110 and at least one electrode element 120 . The optical film stack 110 includes a plurality of optical films 112 with different refractive indices and at least one optical regulation film 114 . In this embodiment, the ...

Abstract

The invention provides an optical accessory used for being arranged on a display surface of a display device. The optical accessory comprises an optical film stack and at least one electrode element. The optical film stack comprises a plurality of optical films with different refractive indexes and at least one optical regulation and control film. The at least one electrode element is correspondingly and electrically connected to the at least one optical regulation and control film, the reflectivity of the optical film stack to ambient light is smaller than or equal to 1%, and the at least one optical regulation and control film is suitable for increasing the reflectivity to the ambient light to be larger than or equal to 1% by applying voltage.

Description

technical field [0001] The invention relates to an optical device, in particular to an optical accessory. Background technique [0002] Generally speaking, the surface of electronic screens (such as computer monitors, robots, smart phones or tablet computers, etc.) is often coated with an anti-reflection layer to reduce the reflection caused by ambient bright light and reduce visibility. Specifically, a single layer or multiple layers of material can be coated between the transparent substrate and the air to reduce the reflection at the interface between the glass and the air. [0003] However, in general electronic screens, the coated anti-reflection layer is a passive optical functional layer. In other words, other types of optical effects cannot be produced through further control. If it can be changed to an active optical function layer, the electronic screen can provide more uses when viewed, such as color changing or privacy functions such as anti-peeping. Therefore...
