Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
As described in the background section, available liquid crystal display screen is gradually expanded to the camber display screen under vehicle-mounted equal application scenarios,
And in camber display screen in addition to being bent liquid crystal display panel, it is also necessary to which touch panel and backlight module carry out processing curved
It is bent.It is first to be bent the backboard of rigidity, then lamp plate bending is fitted in backboard when carrying out processing bending for backlight module
On, since lamp plate and backboard rigid are inconsistent, and there is certain bending stress in the bent state, thus mutually it
Between be easy by different influenced of stress to be generated separation, the lamp plate after separation is easy to produce position and moves due to not fixing
It is dynamic, the variation of light source position on lamp plate is further resulted in, in the case where back light changes, the backlight of backlight module is held
Local unevenness is easily led to, the whole display effect of display panel is influenced.
In view of the above-mentioned problems, the backlight module includes: curved surface glue frame the embodiment of the invention provides a kind of backlight module,
