Abstract

The invention relates to the technical field of display, and provides a circuit board structure, a backlight module, a display module and a touch display module, the circuit board structure comprises a flexible circuit board, a first circuit hard board and a second circuit hard board, and the flexible circuit board comprises a fitting part and a bending part. The orthographic projection of the first circuit hard board on the flexible circuit board covers the fitting part and covers at least partial area of the bending part; the orthographic projection of the second circuit hard board on the flexible circuit board is overlapped with the fitting part; therefore, when the bending part of the flexible circuit board is bent towards the second circuit hard board, the bending range of the bending part is increased; and the bending part is at least partially positioned below the first circuit hard board, so that the visual range of the visual area is ensured, and the space is saved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a circuit board structure, a backlight module, a display module and a touch display module. Background technique [0002] In the related art, the rigid-flex circuit board is laminated by arranging a flexible circuit board between two hard circuit boards. However, when it is applied to a display module, there is a bent portion of the flexible circuit board under the visible area of ​​the display module, so that the visible range of the visible area is reduced. Contents of the invention [0003] Based on this, it is necessary to address the above technical problems and provide a circuit board structure, a backlight module, a display module and a touch display module to ensure the visible range of the visible area. [0004] According to one aspect of the present application, the embodiment of the present application provides a circuit board structure, including: [00...
