Abstract

The invention provides a light source module, a manufacturing method thereof and a display device. The light source module comprises a substrate and a plurality of light-emitting units arranged on the substrate, each light-emitting unit is composed of a reflection cup, a first LED and a second LED, in the same reflection cup groove, the first LED is arranged at the focus position of the reflection cup groove, and at least part of light emitted by the first LED is emitted in a collimation mode after being reflected by the inner wall of the groove; the second LED is arranged at a non-focus position of the groove of the reflecting cup, and light emitted by the second LED is reflected by the inner wall of the groove and then is scattered and emitted; the first LED and the second LED in each light-emitting unit are independently controllable, and when the first LED is controlled to independently display, narrow-view-angle display can be achieved for peep prevention; and when the second LED is controlled to display, wide-viewing-angle display can be realized for shared display.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a light source module, its manufacturing method and a display device. Background technique [0002] With the development of display technology, the light output angle of existing flat panel displays is very large. The large viewing angle brings excellent user experience to consumers in some applications such as TV products, but in some applications such as personal mobile products or special In the application occasion, it will cause the leakage of personal information or privacy, or in the car display, passengers watching videos will interfere with the driver, resulting in danger. In response to this problem, the technology development of anti-peeping or switching viewing angle display has been put on the agenda. Contents of the invention [0003] The purpose of the present application is to provide a light source module, a manufacturing method thereof, and a displ...
