Description

Electronic device

This creation is about an electronic device. More specifically, the present invention relates to an electronic device having a reflective layer.

With the development of technology, many electronic devices today integrate camera modules to achieve versatile use. For example, many notebook computers have a photographic lens on top of the screen for video.

However, when the user uses the aforementioned photographic lens, the user can only view the image through the image of the camera back to the screen. In addition to the delay problem, the user cannot observe himself without turning on the photographic lens. Furthermore, when the photographic lens is used in a situation where the external ambient light is insufficient, it is difficult for the user to view the user by the video lens, either by the user or by the user. Therefore, how to solve the above problems has become an important issue.

In order to solve the above problems, the present invention provides an electronic device including a housing, a display panel, a backlight module, and a reflective layer. The display panel and the backlight module are disposed in the housing, and the backlight module has a light emitting surface facing the display panel. The reflective layer is disposed on the display panel, and the display panel is located between the reflective layer and the backlight module.

In an embodiment of the present invention, the reflective layer comprises a glass substrate And a metal film, and the metal film is applied to the glass substrate by a non-conductive vacuum metallization (NCVM) method. The metal film may be disposed between the display panel and the glass substrate, or the glass substrate may be disposed between the display panel and the metal film. The light from the backlight module can penetrate the reflective layer.

In an embodiment of the present invention, when the backlight module does not provide light, external light that is directed toward the reflective layer is reflected by the reflective layer. When the electronic device is in a fill mode, the backlight module provides a portion of the light passing through the reflective layer to form at least one bright region and at least one dark region on the reflective layer. In an embodiment of the present invention, the electronic device further includes an imaging lens disposed on the housing and corresponding to the dark area. The electronic device can be, for example, a notebook computer, a tablet computer, a smart phone, or a display screen.
