Patent ID: 11119590

Abstract:
An opto-electronic module includes a circuit board, a light-emitting assembly, a contact sheet, a light shielding structure, and an outer block. The circuit board has a surface and a groove on the surface. The light-emitting assembly includes a light guide plate and a light-emitting element set. The contact sheet is above the light guide plate. The light shielding structure is above the light guide plate or below the contact sheet. The light shielding structure has an opening. The opening corresponds to a microstructure. The outer block is at an outer periphery of the light guide plate, there is a gap between the outer block and the light guide plate, and the outer block is between the contact sheet and the circuit board. One end of the groove is in communication with the gap, and the other end of the groove is in communication with the environment outside the opto-electronic module.
