AI Technical Summary
Technical Problem
The existing air conditioner display panel has obvious dark areas caused by direct light from the LED beads, which affects the visual effect.
Method used
The system employs a combination of circuit board, light shield, LED beads, and PET diffusion film. The LED beads emit light from the side and diffuse the light through the light guide ring groove. Combined with the viscous ink of the diffusion powder particles, uniform light diffusion is achieved.
Benefits of technology
Seamless connection between LED beads and continuous, uniform light halo have been achieved, improving the visual effect of air conditioner display.

Abstract
This utility model relates to a structure for a light-emitting ring without dark areas on an air conditioner display panel. It comprises: a circuit board, a light shield, several LED beads, and a PET diffusion film. The light shield is assembled on the circuit board and has a light guide ring groove. Several LED beads are spaced apart and embedded in the light guide ring groove and connected to the circuit board. The LED beads emit light from the side, causing the light emitted by the LED beads to be directed onto the side wall of the light guide ring groove and diffused through the side wall before reaching the opening of the light guide ring groove. The PET diffusion film is installed on the light shield and effectively covers the opening of the light guide ring groove. The back of the PET diffusion film is printed with viscous ink containing diffusing powder particles, allowing the diffused light to be re-excited and uniformly diffused by the diffusing powder particles in the viscous ink, presenting a continuous, dark-area-free halo. This solves the problem of dark areas appearing in the intervals between multiple front-emitting LED beads, resulting in a continuous, uniform halo with excellent visual effects, which is beneficial for air conditioner display implementation.
