Problems solved by technology

The light emitted by the light source is scattered, but the larger the angle, the smaller the intensity of the light. Therefore, the position between the two light sources is very easy to appear dark areas due to insufficient light, which affects the display of the display panel.

Abstract

The invention discloses a backlight module and an electronic device. The backlight module comprises a light guide plate, a plurality of light sources and brightening layers. The light guide plate comprises a light inlet face and a light outlet face. The light sources are arranged on the side, with the light inlet face, of the light guide plate and are arranged at intervals. Each brightening layeris arranged between every two adjacent light sources and used for improving the luminance between the two adjacent light sources, so that it is avoided that a dark area appears between two adjacent light sources. Therefore, the backlight module is uniform in outlet light, and the light and shade parallax is avoided.

Description

technical field [0001] The present application relates to the field of backlights of electronic devices, in particular to a backlight module and an electronic device. 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-type backlight module, that is, the light emitted by the light source enters the light guide plate from the side of the light guide plate, and is guided by the light guide plate. Then provide backlight for the display panel of the electronic device. The light emitted by the light source is scattered, but the larger the angle, the lower the intensity of the light. Therefore, the position between the two light sources is very easy to appear dark areas du...
