Problems solved by technology

[0002] In order to reflect the light and thin design of current electronic products, the thin structure of the backlight module has always been the focus of research and development by various manufacturers. Please refer to figure 1 Shown is a schematic diagram of a display device designed using a traditional backlight module, from figure 1 It can be seen from the structure that in the current assembly structure, the printed circuit board (PCBA) with the function of driving liquid crystals is folded behind the backlight module and bonded to the frame (Bezel); while the light-emitting element (LED) uses The circuit board and the aforementioned printed circuit board (PCBA) are two independent circuit boards. The existing design uses a flexible circuit board (FPC) to combine the aforementioned two circuit boards (light-emitting element (LED) circuit board and Printed circuit board (PCBA)) connection, this design not only has more components, but also the assembly thickness of the display device cannot be reduced, which cannot meet the current thinning requirements

Abstract

The invention provides a backlight module and a display device comprising the same. The display device at least comprises a display module, a backlight module and a flexible circuit board; the backlight module at least comprises a frame, a drive circuit board, light-emitting elements, and an optical component; the display component is disposed on the frame; the flexible circuit board is connected with both the display module and the drive circuit board; in addition, the frame is provided with an accommodating cavity in which the drive circuit board is disposed; one side of the drive circuit board is provided with a drive circuit structure, and the light-emitting elements are disposed on the other side of the drive circuit board. The design that both the light-emitting elements and the drive circuit structure are arranged on the drive circuit board is adopted, the drive circuit board is disposed inside the corresponding accommodating cavity, and accordingly, fewer parts are used and the requirement for decreasing assembly thickness can be met.
