Display module and method for manufacturing same, and display device

A method for manufacturing a display module, comprising:

• providing a shell;
• and
• disposing a display panel, a first light emitting component and a fingerprint recognition sensor in the shell;
• wherein the display panel is connected to the shell;
• the first light emitting component is connected to the display panel and is configured to emit light of a target wavelength;
• the fingerprint recognition sensor is disposed between the shell and the display panel and is fixedly connected to the shell;
• an orthographic projection of the fingerprint recognition sensor onto the display panel and an orthographic projection of the first light emitting component onto the display panel do not overlap;
• and the fingerprint recognition sensor is configured to recognize a fingerprint based on the received light of the target wavelength reflected by an obstacle.

A display device, comprising a power supply component and a display module that is connected to the power supply component, wherein the power supply component is configured to supply power to the display module;

• and the display module comprises:
• a shell;
• a display panel, wherein the display panel is disposed in the shell and is connected to the shell;
• a first light emitting component, wherein the first light emitting component is connected to the display panel and is configured to emit light of a target wavelength;
• and
• a fingerprint recognition sensor, wherein the fingerprint recognition sensor is disposed between the shell and the display panel and is fixedly connected to the shell;
• an orthographic projection of the fingerprint recognition sensor onto the display panel and an orthographic projection of the first light emitting component onto the display panel do not overlap;
• and the fingerprint recognition sensor is configured to recognize a fingerprint based on the received light of the target wavelength reflected by an obstacle.
