Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
Please refer to Fig. 1, a kind of display screen guard assembly 10 provided by the embodiment of the utility model, for protecting outdoor liquid crystal
Display screen 20 is set to including UV resistance film 11, glass cover-plate 12 and the anti-reflection film 13 reflected for weakening light, glass cover-plate 12
Between UV resistance film 11 and anti-reflection film 13, UV resistance film 11 has the first side 111 that connect with glass cover-plate 12 and back to the
One side 111 is arranged and the second side 112 for being arranged towards outdoor liquid crystal display screen 20.
20 surface of liquid crystal display sets the display screen guard assembly 10 outdoors, and UV resistance film 11 has UV resistance effect,
Can be avoided strong ultraviolet radiation declines 20 resistance of outdoor liquid crystal display screen, and power consumption increases, colour changed into yellow, clarity decline,
The problem of screen is dimmed, blackening, improves the performance of outdoor liquid crystal display screen 20.In addition, the setting of anti-reflection film 13 can increase
Light reflection is reduced while light transmittance, while effectively weakening the shortcoming that strong illumination causes surface to bleach display is imitated
Fruit is more true to nature.
As preferred embodiment, UV resistance film 11 is connect by bonding way with glass cover-plate 12.Further, prevent
The first side 111 of ultraviolet film 11 is bonded on glass cover-plate 12 by optical cement.Specifically, UV resistance film 11 includes carrier
