Problems solved by technology
[0004] Originally, the backlight light source was fixed by bonding the flexible circuit board and the light guide plate. After the flexible circuit board bound to the light-emitting unit is narrowed, the bonding area between the flexible circuit board and the light guide plate is reduced, and the fixing strength of the backlight light source is reduced, resulting in The backlight light source is easy to shift or fall off, resulting in a decrease in the display effect of the display panel or failure to display normally

The present invention provides a backlight module and a display panel. The backlight module includes: a frame body including a frame and a bottom plate, the frame surrounds the bottom plate, and the bottom plate includes a groove portion and a non-groove portion sequentially arranged in a first direction ; The flexible circuit board is arranged in the groove portion, including a first surface and a second surface oppositely arranged, wherein the first surface is fixed to the bottom surface of the groove portion, and in the first direction, the second surface includes The first part of the surface of the groove part and the second part of the surface close to the non-groove part; a plurality of light emitting units, fixed on the first part of the surface; the light guide plate, including the dot surface close to the bottom plate and the smooth surface away from the bottom plate, the light guide plate is made of non- The groove portion extends to the groove portion, and the dot surface extending to the groove portion is fixed to the surface of the second part. The backlight module provided by the present invention can remarkably improve the fixing strength of the backlight light source, and reduce the risk of display effect degradation or normal display failure caused by backlight light source shifting or falling off.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a backlight module and a display panel. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for display panels. In order to achieve a better display effect, it is necessary to further increase the screen-to-body ratio, that is, increase the area of the display area of the display panel, reduce the area of the frame area, and design the display panel with a narrow frame. [0003] COF (chip on flex) technology can set the integrated circuit chip on the main flexible circuit board, and then realize the control of the integrated circuit chip on the array substrate through the binding of the main flexible circuit board and the array substrate. Originally, the lower border needs to have both the binding area of the integrated circuit chip and the main flexible circuit board. After adopting...
