Electronic device and its display component, backlight module

Abstract

The invention discloses a backlight module. The backlight module includes a light guide plate, a light source, a dodging element, a flexible circuit board, a shading adhesive tape, and a refraction layer, wherein the light guide plate includes an incident end portion and a main body portion of the light guide plate; the light source is arranged at one side, depart from the main body portion of thelight guide plate, of the incident end portion; the dodging element is arranged on the main body portion of the light guide plate; the flexible circuit board is partially arranged on an area, which is not covered by the dodging element, on the light guide plate; a reserved gap is formed between the end portions, approaching to each other, of the flexible circuit board and the dodging element; theshading adhesive tape is covered on the flexible circuit board, and is covered on part of the area of the dodging element; and the refraction layer is arranged in the non-display area of the backlight module, and is used for deflecting the light directly illuminated to the refraction layer to the shading adhesive tape and shielding the light by means of the shading adhesive tape. The invention also discloses an electronic device and a display assembly. By means of the backlight module, on the premise of reducing the width occupied by the non-display area of the backlight module, light leakageof the backlight module can be avoided.

Description

technical field [0001] The invention relates to the technical field of backlights of electronic devices, in particular to an electronic device, a display component thereof, and a backlight module. Background technique [0002] At present, with the development of science and technology, electronic devices such as smart phones have gradually become necessities in people's lives. [0003] The backlight module is an important part of an electronic device. At present, the backlight module of portable electronic devices such as smartphones usually adopts a side-entry backlight module, that is, the light emitted by the light source enters the light guide plate from the side of the light guide plate, so that the The display panel of the electronic device provides backlight.

[0003] The backlight module is an important part of an electronic device. At present, the backlight module of portable electronic devices such as smartphones usually adopts a side-entry backlight module, that is, the light emitted by the light source enters the light guide plate from the side of the light guide plate, so that the The display panel of the electronic device provides backlight. However, since the light source and some related structures of this side-type backlight module need to be arranged on the side of the light guide plate, it occupies a large non-display area, which is not conducive to narrow borders and The realization of the full screen, how to shorten the width of the backlight module in the non-display area without affecting the normal display of the backlight module and the display panel, has become the focus of attention.
