Abstract
The invention relates to a power supply module and a method for producing the same. The power supply module comprises at least one luminescent unit, a light guide plate and at least one optical coupling assembly; the at least one luminescent unit is suitable for emitting a light beam; the light guide plate is provided with a first light emitting surface, a first bottom surface and at least one first light incidence surface, the first light emitting surface is opposite to the first bottom surface, and the first light emitting surface is connected with the first bottom surface through the first light incidence surface; the optical coupling assembly is provided with a second light incidence surface and a second light emitting surface, the luminescent unit is arranged by the side of the second light incidence surface, the light beam enters the optical coupling assembly through the second light incidence surface, the light beam leaves the optical coupling assembly through the second light emitting surface and enters the light guide plate through the first light incidence surface, the first light incidence surface is contacted with the second light incidence surface, and the quantity of the luminescent unit, the first light incidence surface and the optical coupling assembly is identical. By adopting the power supply module, the luminescent efficiency can be improved, the production efficiency can be increased, and the cost can be reduced.
Description
technical field [0001] The present invention relates to a light source module and a method for manufacturing the light source module, and in particular to a light source module with an optical coupling component and its manufacturing method. Background technique [0002] The development and progress of display technology in recent years has led to the popularization of various displays, and has gradually played an indispensable role in the daily life of modern people, such as computer screens, smartphones and e-book screens, often used such as light-emitting diode displays (Light Emitting Diode Display, LED display), organic light emitting diode display (Organic Light Emitting Diode Display, OLED) or electrophoretic display (Electrophoretic Display) and other displays. In order to improve the display quality and increase the convenience of use, the display has been developed towards a thinner and more portable trend. [0003] Wherein, since the liquid crystal display panel ...
