Abstract

The embodiment of the invention discloses a backlight module, a vehicle-mounted display panel and a vehicle. The backlight module comprises a first backlight module and a second backlight module. The first backlight module is provided with an opening, and the second backlight module is installed in the opening. The type of the first backlight module is different from that of the second backlight module, so that the first backlight module and the second backlight module can emit light independently according to different backlight control types, and when one of the first backlight module and the second backlight module breaks down, by means of the other one of the first backlight module and the second backlight module, the backlight module still has the function of providing backlight, and the fault tolerance of the backlight module is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle displays, in particular to a backlight module, a vehicle display panel and a vehicle. Background technique [0002] The use of liquid crystal display panels as vehicle-mounted display panels to display information such as speed per hour and fuel consumption has become the mainstream of vehicle-mounted display technology development. However, since the liquid crystal display panel needs to be equipped with a backlight to achieve display, if the backlight fails, it will cause a full-screen black screen on the vehicle display panel, threatening the driving safety of the driver. Contents of the invention [0003] Embodiments of the present invention provide a backlight module, a vehicle display panel and a vehicle, which can improve the fault tolerance of the backlight module. [0004] An embodiment of the present invention provides a backlight module, including: a first backlight module and a seco...
