Abstract: A light source module and a display module are provided. The light source module includes: a substrate; a plurality of first light sources spaced on the substrate, each of the plurality of first light sources being configured to emit visible light; a depth sensor on the substrate; and a first blocking member configured to shield visible light but transmit invisible light. The depth sensor includes a second light source configured to emit invisible light and a light receiving member configured to sense invisible light, an orthographic projection of the second light source on the substrate is located within an orthographic projection of a gap between two adjacent first light sources on the substrate, an orthographic projection of the first blocking member on the substrate at least partially covers the orthographic projection of the second light source on the substrate.
