Vehicle-mounted display screen and backlight module thereof

Abstract

The invention relates to a vehicle-mounted display screen and a backlight module thereof. The backlight module comprises a lamp panel, a lampshade, a lens, a lower iron frame and a middle iron frame. The lower iron frame is connected with the middle iron frame, and the lamp panel, the lampshade and the lens are all arranged between the lower iron frame and the middle iron frame. The lamp panel is arranged in the lower iron frame, and a plurality of LED lamp beads are arranged on the face, back on to the lower iron frame, of the lamp panel. The lampshade is connected with the face, back to the lower iron frame, of the lamp panel, a plurality of lamp grooves are formed in the lampshade, a first lamp hole is formed in the bottom of each lamp groove, each LED lamp bead penetrates through the corresponding first lamp hole to be located in the corresponding lamp groove, and the lens is connected with the face, back to the lamp panel, of the lampshade. Independent partition of the light source can be achieved through the arrangement of the lampshade, the light channeling phenomenon among all the areas is improved, the display effect of the backlight module is more uniform, and the effect of improving the uniformity of the backlight module is achieved. In addition, the combination of the lens and the lampshade can also play a role in improving lamp shadows, apertures, bright and dark bands and other undesirable phenomena, so that the optical display quality of the backlight module is improved.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to a vehicle-mounted display screen and a backlight module thereof. Background technique [0002] In the existing vehicle-mounted display screen, due to the phenomenon of flashing light between the display areas of each partition in the backlight module, the display brightness between the various areas of the vehicle-mounted display screen is uneven, resulting in poor display effect of the vehicle-mounted display screen . At the same time, the backlight module of the existing vehicle-mounted display still has undesirable phenomena such as light shadows, apertures, and bright and dark bands, which makes the display effect of the vehicle-mounted display poor, resulting in poor user perception. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle-mounted display screen and its backlight module, so as to solve the problems mentione...

AI Technical Summary

Problems solved by technology

[0002] In the existing vehicle-mounted display screen, due to the phenomenon of flashing light between the display areas of each partition in the backlight module, the display brightness between the various areas of the vehicle-mounted display screen is uneven, resulting in poor display effect of the vehicle-mounted display screen

At the same time, the backlight module of the existing vehicle-mounted display still has bad phenomena such as light shadows, apertures, and bright and dark bands, which makes the display effect of the vehicle-mounted display poor, resulting in poor user perception.
