Problems solved by technology
[0003] However, the inventors of the present application found that the current method is limited to the limit of the processing thickness of the parts, and the frame design of the backlight module cannot be further reduced, especially the distance between the display area of the display panel and the outer edge of the printed circuit board. It is difficult to reduce; and due to the thinner component thickness of the current design method, the overall strength of the backlight module will also decrease, and it is inevitable that there will be fragments, abnormal sounds, and abnormal pictures when testing the whole system. various problems

The present application provides a backlight module, a display module, and a display device, which are used to realize the narrow frame of the backlight module, enhance the overall strength of the backlight module, and prevent problems such as fragmentation, abnormal sound, and abnormal picture. The backlight module includes a backplane, a light guide plate, a light bar and a printed circuit board; the backplane includes a bottom plate, a side plate and a top plate; the side plate is between the bottom plate and the top plate, and the top plate is used to carry the display panel; the printed circuit board and the display The panels are connected and arranged in the accommodation space formed by the top board, the side boards and the bottom board; the luminous light bar is arranged in the accommodation space and embedded in the side of the printed circuit board facing the light guide plate. Since the printed circuit board is arranged in the accommodation space, and the light-emitting light bar is embedded in the side of the printed circuit board facing the light guide plate, the external space occupied by the original printed circuit board is saved, and the vertical space of the backlight module can be reduced. Directional size, realize narrow frame setting, and can enhance the overall strength of the backlight module, preventing problems such as fragmentation, abnormal sound, and abnormal picture.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a backlight module, a display module, and a display device. Background technique [0002] At present, the demand for ultra-narrow bezels in the notebook (Notebook, NB) market is becoming increasingly fierce, and the design of backlight modules for ultra-narrow bezels is usually achieved by continuously reducing the thickness of the internal parts of the backlight. [0003] However, the inventors of the present application found that the current method is limited to the limit of the processing thickness of the parts, and the frame design of the backlight module cannot be further reduced, especially the distance between the display area of the display panel and the outer edge of the printed circuit board. It is difficult to reduce; and due to the thinner component thickness of the current design method, the overall strength of the backlight module will also decrease, a...
