Display assembly and display device

A display assembly, comprising:

• a display panel;
• a cover plate, disposed on a display side of the display panel;
• a diverging element, wherein the diverging element and the display panel are located on a same side of the cover plate, and the diverging element is disposed in a non-display region of the cover plate and is configured to diverge received light and emit diverged light;
• an emission module, configured to emit light, wherein the emission module is disposed on a non-display side of the display panel and faces the diverging element;
• and
• a receiving module, disposed on the non-display side of the display panel and configured to receive reflected light that is formed by a detection target through reflecting light diverged by the diverging element;
• wherein the emission module comprises:
• a light source, configured to emit light;
• and
• an optical component, configured to receive the light emitted by the light source and transmit the received light to the diverging element;
• wherein the emission module further comprises:
• a light collimator, wherein collimated light is transmitted from the light collimator after the light emitted by the light source is collimated by the light collimator, and the optical component adjusts the collimated light and transmits adjusted light to the diverging element.
