Abstract

The invention provides a light source module comprising a substrate and a plurality of light-emitting units. The light-emitting units are arranged on the surface of the substrate, and each light-emitting unit comprises a first light-emitting element, a second light-emitting element, a first reflecting element, a second reflecting element and a packaging structure. The packaging structure comprises a main body part and a first groove. The main body portion covers the first light-emitting element and the second light-emitting element. According to the light source module, the light emitting uniformity of the light source module can be improved.

Description

technical field [0001] The present invention relates to a backlight module, and in particular to a light source module. Background technique [0002] With more and more applications of non-self-illuminating displays (for example, liquid crystal displays), the design of the backlight module also needs to be adjusted for different applications. In order to meet the requirements of large-size, high dynamic range (HDR) and high-contrast displays, the backlight module needs to have a local dimming function. Therefore, the direct-lit type backlight module using light-emitting diodes as the main light source has gradually become the mainstream of the market. Since the total thickness of this type of backlight module is thin (for example, the light distance is less than 10 mm), the LEDs are usually covered by a packaging layer with a light-emitting structure to achieve a more uniform light-emitting effect on the light-emitting surface of the backlight module. However, when the lig...
