Abstract

The invention provides a backlight module and a display panel, the backlight module comprises a back plate and a widening component, the back plate comprises a bottom plate and an outer frame fixedly connected with the bottom plate, and the outer frame surrounds the bottom plate to form a containing cavity. The widening component is arranged on at least one side, away from the containing cavity, of the outer frame and detachably connected with the outer frame. By arranging the widening component fixedly connected with the outer frame, the overall width of the outer frame can be adjusted, so that when the vehicle-mounted display screen with the same visual area size but different overall dimensions is dealt with, only the widening component needs to be replaced, the overall overall dimension requirement can be met, the outer frame can be shared, and then an outer frame mold is shared; the number of backlight outer frame mold opening is obviously reduced, and the backlight cost is reduced.

Description

Technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and display panel. Background [0002] With the development of the modern automotive industry, the equipment in the car is more and more pursuing personalized design while meeting the basic functions. Among them, the car display screen is a non-standard part, and there are various customization needs in the product development process. At present, the size of the visible area of the car display on the market is relatively fixed, but due to the different design of the car, the car display of the same viewable area size often has many external dimensions. The shape structure of the car display screen mostly adopts the combination scheme of bottom sheet metal and outer frame. For models with the same size of the viewing area but different external dimensions, a special backlight mold is required to make the outer frame of the car display, which in turn leads...
