Electronic device and its display component, backlight module

Abstract

The invention discloses a backlight module. The backlight module comprises a back frame, an optical module, a flexible printed circuit board, a light source and a supporting piece, wherein the back frame comprises a bottom wall and a side wall which is in bend connection with the bottom wall, and a containing space is formed through the bottom wall and the side wall; the optical module is arrangedon the bottom wall and located in the containing space; the flexible printed circuit board is arranged on an area which is not covered with the optical module of the bottom wall, and is partly overlapped with the optical module; the light source is arranged on one surface, away from the bottom wall, of the flexible printed circuit board, and is opposite to the side edge, towards the side wall, ofthe optical module; the supporting piece is arranged on the light source and / or the optical module and used for supporting a display panel. The invention also discloses a display module and an electronic device. According to the mode, under the condition that the width occupied by a non-display area of the backlight module can be reduced, the stability when the backlight module supports the display panel is guaranteed.

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.
