Abstract

The invention discloses a display module and a backlight module. The display module includes the backlight module and a display panel arranged on the backlight module. The backlight module includes a base plate, a light guide plate, a support frame, a buffer material and a baffle. The light guide plate is arranged on the base plate and includes the top face, the bottom face and a plurality of side faces connecting between the top face and the bottom face. The support frame surrounds the light guide plate. The buffer material is arranged on at least one side of the light guide plate and includes the top wall, the bottom wall and the side wall. The top wall is arranged on the outer periphery of the top face of the light guide plate. The bottom wall leans between the base plate and the bottom face of the light guide plate. The side wall connects with the top wall and the bottom wall and wraps at least one side face of the light guide plate. The baffle is arranged on the base plate vertically and is disposed on at least one side of the light guide plate. The side wall of the buffer material leans between the baffle and at least one side face of the guide plate.

Description

technical field [0001] The present invention relates to a backlight module and a display module, and in particular to a backlight module and a display module which can take into account both the stress buffering of the light guide plate and the positioning effect of the optical film. Background technique [0002] With the increasing maturity of optoelectronic technology and semiconductor manufacturing technology, flat panel display devices are developing vigorously. Among them, the liquid crystal display has gradually replaced the traditional cathode ray tube display due to its advantages of low voltage operation, no radiation scattering, light weight and small size, and has become the mainstream of display products in recent years. [0003] figure 1 A conventional liquid crystal display module is shown. Figure 2A for figure 1 A cross-sectional view of an LCD module. Figure 2B for figure 1 Another cross-sectional view of the LCD module. In order to clearly express th...
