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 . For example, the optical accessory 100 is directly fabricated on the display surface S of the display device 10 , or is detachably arranged on the display device 10 , but the present invention is not limited thereto. For example, the optical accessory 100 may be a screen pendant mounted on the display device 10 to cover the display surface S. As shown in FIG.

[0034] Specifically, 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 control film 114 . In this embodiment, t...

Abstract

The present invention provides an optical accessory, which is arranged on a display surface of a display device. The optical accessory includes an optical film stack and at least one electrode element. The optical film stack includes a plurality of optical films with different refractive indices and at least one optical control film. At least one electrode element is correspondingly electrically connected to at least one optical control film, wherein the reflectivity of the optical film stack to ambient light is less than or equal to 1%, and the at least one optical control film is suitable for increasing the reflectivity to ambient light by applying a voltage greater than or equal to 1%.

Description

technical field [0001] The present 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.) are often coated with anti-reflection layers to reduce reflections caused by ambient light and reduce visibility. In a specific method, 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 a general electronic screen, the coated anti-reflection layer is a passive optical functional layer. In other words, there is no further control to produce other kinds of optical effects. If it can be changed to an active optical function layer, the electronic screen can provide more uses when being viewed, for example, security functions such as discoloration or privacy pro...
