Abstract

The invention provides a backlight module and a display panel. The backlight module sequentially comprises an optical film group, a light guide plate, a reflection sheet and a bottom plate, and further comprises a frame connected to the bottom plate and arranged opposite to the side surface of the light guide plate, wherein a gap exists between one end of the optical film group and the frame. Thetechnical effect of the backlight module is that the gap is reserved on one side of the optical film group, so that the optical film group still remains flat at high temperature, high optical characteristics are kept, and the product competitiveness is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight module and a display panel. Background technique [0002] With the development of vehicle-mounted display technology, the requirements for the appearance of vehicle-mounted display modules are getting higher and higher, and the requirements for the frame of vehicle-mounted LTPS display modules are also getting narrower. [0003] Due to the high reliability requirements of the on-board display, if the optical diaphragm group in the backlight is not fixed, there will be a problem of abnormal sound when the backlight module shakes, and the friction between the optical diaphragm group and the light guide plate will cause the optical diaphragm to Group and light guide plate scratches cause poor optics. Due to material problems (such as PET substrate), the optical diaphragm will expand at high temperature. If the space distance between the diaphragm and the frame is not enough, the dia...
