AI Technical Summary

Technical Problem

The characters of the existing vehicle instrument screen are uneven in brightness, resulting in the problems of brightness in the middle and dark edges, affecting the display effect.

Method used

A vehicle-mounted instrument assembly with uniform character brightness is designed, adopting a clamped connection structure between the shell and the cover plate. A black ink layer is provided on the cover plate, and a light emitting area is provided on the shell. A trumpet-shaped light emitting body and LED lamp beads are provided in the light emitting area. A rectangular frame and characters are provided on the back of the cover plate. A semi-transmissive black ink layer and a white diffused ink layer are provided on the outer edge of the character outline. The second silver oil ink layer is located at the near end of the character to increase reflected light.

Benefits of technology

Through the reflective effect of the second silver oil ink layer, the phenomenon of brightness and darkness in the middle of the characters is reduced, and the uniformity of the characters is improved.

Abstract

The utility model discloses a vehicle-mounted instrument assembly with uniform character brightness, which comprises a shell and a cover plate, the cover plate is connected with the shell in a clamping manner, the shell is provided with a luminous area for providing illumination for characters, the luminous area is internally provided with a plurality of trumpet-shaped luminous bodies, the bottoms of the luminous bodies are provided with LED lamp beads, and the LED lamp beads are connected with the shell. A plurality of rectangular frames are arranged on the reverse side of the cover plate, characters are arranged in the rectangular frames, and a semi-transparent black ink layer and a white diffusion ink layer are arranged at the preset distance of the outline periphery of each character. As the second silver oil ink layer is located at the near end of the character, the character obtains an enhancement effect of reflected light through light reflection of the second silver oil ink layer, the effect that the middle of the character is bright and the distance of the character is dark is reduced, and the display uniformity effect of the character is effectively improved.
