Abstract: The present disclosure provides a backlight module and a display panel, wherein the backlight module includes a backboard and a widening member, the widening member is disposed on at least one side of the outer frame opposite to the accommodation chamber and detachably connected to the outer frame. As such, when on-board display screens having a same visual area size but different appearance sizes are used, only the widening member needs to be changed to meet the requirements of the overall appearance size. The outer frame can be used in common, and thus a mold for the outer frame can be used in common, thereby significantly reducing the number of mold of the outer frame of the backlight module, and thereby reducing a cost of the backlight module.

Abstract: A backlight module and a liquid crystal module are provided. The backlight module has a backplate, a light source, a light guiding element, an optical film and a plastic frame. The backplate has a bottom plate and side plates. The bottom plate and the side plates form a receiving chamber. The light source, the light guiding element and the optical film are disposed inside the receiving chamber. The plastic frame is disposed on the backplate. At least one of the side plates is provided with a recess portion at a position corresponding to the optical film, and the recess portion faces toward the optical film. When the optical film is thermally expanded, it extends toward the recess portion.

Abstract: The present application provides a display panel and an electronic device. The electronic device includes a display panel. The display panel includes a backlight module. The backlight module includes a frame, an optical film group, and a fixing block. Movements of the optical film group can be limited in a thickness direction of the display panel by pressing the fixing block on the optical film group. Therefore, optical films can be fixed, so problems of abnormal noise, displacement, and scratches of the optical films in the display panel adopting a direct-lit mini light-emitting diode (LED) light source are prevented.

Abstract: A backlight module and a display panel are provided. The backlight module includes a first engagement structure and a second engagement structure. By engaging the first engagement structure with the second engagement structure, a sealant and a bottom frame are fixed to each other to fix an optical film, thereby preventing the optical film from shifting and vibration scratches. Therefore, it is prevented to provide a positioning post for fixing the optical film on the light guide plate, and the applicability of a thermal-pressing process of the light guide plate is improved.

Abstract: A display system includes a display module, a projection component, and a projection bearing component. The projection component is disposed with respect to a display side defined by a second liquid crystal panel. The projection bearing component is disposed with respect to a side of the projection component away from the display module. The projection component is configured to project a display image of the second liquid crystal panel onto the projection bearing component.

Abstract: The present invention provides a sealing frame, a backlight module, and a display device. A supporting portion is disposed in a first placement slot of the sealing frame configured to accommodate a flexible printed circuit board such that when the flexible printed circuit board experiences a pulling force during assembling thereof to the backlight module, supporting portion supports the flexible printed circuit board and prevents flexible printed circuit board from suffering an excessive pulling force and transferring the force to the liquid crystal display panel to result in variation of a portion of a cell gap of the liquid crystal display panel.

Abstract: A backlight module and a liquid crystal module are provided. At least one of side walls of a back plate in the backlight module is provided with an avoidance gap at a location corresponding to an optical film. A height of the avoidance gap is greater than or equal to a thickness of the optical film. By disposing the avoidance gap at the location of the side wall corresponding to the optical film, when the optical film is thermally expanded, the deformed optical film is located within the avoidance gap, and thus the optical film does not generate wrinkles caused by the expansion being impeded.

Abstract: A backlight module and a display device are provided. The backlight module has a plastic frame and a light guide plate located in the plastic frame. Convex portions and groove portions aligned to the convex portions are formed on the plastic frame to form an elastic structure. One of the convex portions is configured to contact with a sidewall of the light guide plate, and one of the convex portions is offset toward a side of one of the groove portions by being pressed by the light guide plate, thereby deforming one of the groove portions, so that the elastic structure and the light guide plate form an interference fit. Therefore, the light guide plate is fixed in the plastic frame without offset.
