Description

Technical Field

[0001] The utility model relates to the field of display technology, and in particular to an anti-peeping oncell-AMOLED display screen and a smart watch. Background Art

However, if smart watches are used in public places, it is inevitable that there will be security issues such as leakage of personal information and related technical information, so anti-peeping settings are required. The existing method is to apply a layer of anti-peep film on the outside of the display cover to protect privacy, but since the cover of smart watches often has the structural characteristics of 2.5D and curved on all sides, the effect of adding anti-peep film on the flat surface of the cover is not good, the edges are not well attached, dust is easily infiltrated, and even warping and falling off are easy.
