Abstract

The invention discloses a light emitting device and a backlight module provided with the light emitting device. The backlight module includes a light guide structure and the light emitting device, the light guide structure includes two light guide members and a reflection sheet arranged between the light guide members. The light emitting device is arranged adjacent to the light guide structure and includes an insulating carrier and two light sources arranged on the insulating carrier. The insulating carrier includes a positioning groove structure, the edge of the reflecting sheet is arranged in the positioning groove structure, the two light sources are respectively corresponding to the two light guide members, and the light emitted by the two light sources can respectively enter into the corresponding light guide members respectively. Therefore, the light emitting device as a single structure can supply the light required by the two light guide member respectively at the same time, and the combination accuracy of the light guide structure and the light emitting device is improved by means of the positioning structure on the light emitting device.

Description

technical field

[0001] The invention relates to a light-emitting device and a backlight module, in particular to a light-emitting device capable of providing dual light sources and a backlight module provided with the light-emitting device to provide double backlights. Background technique

[0002] With the diversification of consumers' usage habits, display devices that provide front and rear dual screens on a single device structure have come into the market. Generally, the backlight module of dual screens has a design structure that uses a single light emitting device to provide light to two light guide plates at the same time, or uses a single light emitting device to provide light to a light guide plate, and then utilizes a semi-transparent and semi-reflective design to divert the light in the light guide plate Introducing another design structure of the light guide plate, or adopting a design structure in which two light emitting devices respectively correspond to a li...
