AI Technical Summary
Technical Problem
Automotive displays experience vibration-induced noise and wear due to friction between components, despite existing solutions that improve casing rigidity, as they fail to address gaps and assembly tolerances in backlight modules.
Method used
A backlight module design featuring a housing with a light guide plate and elastic limiting members that protrude from grooves in the plate, preventing collisions and noise by limiting the light guide plate's movement during thermal expansion and contraction.
Benefits of technology
The design effectively reduces noise and wear by buffering the light guide plate's movement, ensuring stable operation in high-vibration and temperature-variable environments.

Abstract
A backlight module includes a housing, a light guide plate, a light source and an elastic retainer. The housing includes a backplate and a sidewall having a first wall portion. The light guide plate is disposed in the housing and has a first lateral edge and a recess. The first lateral edge corresponds to the first wall portion of the sidewall. The recess has a side opening at the first lateral edge. The light source is disposed in the housing and faces the light guide plate. The elastic retainer is disposed in the recess of the light guide plate and projects from the first lateral edge of the light guide plate via the side opening of the recess.
