The present disclosure relates to a collimated light source assembly, a method for manufacturing a collimated light source assembly, and a display device. The collimated light source assembly includes: a photoelectric conversion unit; at least one light emitting unit, each light emitting unit is suitable for emitting light; and a light collimating structure located in the light emitting direction of the at least one light emitting unit, wherein the light collimating The structure is configured such that a part of light emitted from each light emitting unit passes as a collimated light beam, and another part of light emitted from each light emitting unit is received by the photoelectric conversion unit. According to the collimated light source assembly, the display device and the method for manufacturing the collimated light source assembly of the present application, the photoelectric conversion unit is used to recycle other light that cannot be used to generate the collimated light beam, thereby reducing the light loss of the light emitting unit and increasing the light output. The utilization efficiency is high, and the required collimated beam can be obtained at the same time.
Description
technical field [0001] Embodiments of the disclosure relate to a collimated light source assembly, a display device, and a method of manufacturing a collimated light source assembly. Background technique [0002] Various light sources are used in lighting, LCD display backlight, light boxes, etc. In addition to lasers, the general light source is usually a scattering light source with a large light emitting angle, and the emitted light is emitted uniformly within a large angle range without a specific direction. However, in some applications, it is only necessary to use the light beam emitted from the light source with a certain direction or within a predetermined divergence angle range. For example, in an LCD display using a light-emitting unit such as LED or OLED as a backlight source, if the light emitted by the light source is collimated and controlled, a collimated beam emitted in a predetermined direction can be generated to meet specific application scenarios such as...
