2results about How to "Improve backlight effect" patented technology

This invention provides a direct-lit fiber optic backlight module, including a light-emitting component and an optical fiber. The light-emitting component's light-emitting end is connected to the light-input end of the optical fiber. The optical fiber includes a core, an outer sheath, and multiple exposed sections with the sheath removed. Each exposed section of the core has multiple light emission points. A semi-transparent layer covers the light emission points on the exposed sections of the core, and a light diffusing agent is placed within the semi-transparent layer. The outer surface of the semi-transparent layer has a textured surface. This invention not only significantly reduces the backlight thickness but also provides excellent light emission, improving the overall performance of the backlight.

The invention discloses a backlight module structure and a working control method thereof.The backlight module structure comprises a lamp panel, a lampshade plate and an optical film which are sequentially arranged in a stacked mode from bottom to top, a plurality of light guide covers are arranged on the lampshade plate in an array mode, a plurality of lamp beads are arranged on the lamp panel in an array mode, and the lamp beads are arranged in the light guide covers in a one-to-one correspondence mode to form light emitting areas; each surface of each light guide cover is inclined, the width of each light guide cover is gradually increased from bottom to top, the bottom of each light guide cover abuts against the lamp panel, and a partition wall is formed between each light guide cover on the lampshade plate and the adjacent light guide cover around the light guide cover; the partition walls are made of materials with the light transmittance of 10%-50%. By the adoption of the method, when individual lamp beads of the liquid crystal screen break down, the normal backlight effect of the partition where the lamp beads are located can still be guaranteed, the corresponding display area on an automobile instrument panel can still keep the sufficient display effect, a driver can normally read instrument information in real time, the automobile condition can be accurately known in time, driving safety is guaranteed, and the driving safety is improved. And moreover, the provided illumination is more uniform, and the display effect can be improved.
