Problems solved by technology

However, the traditional way of fixing the integrated circuit board will cause: when the integrated circuit board is fixed too tightly, the integrated circuit board will be displaced towards the direction of the display panel due to the locking force of the screw, which will cause the integrated circuit board to The space between where the FPC is attached on the top and where the display panel is attached to the FPC is reduced, causing the FPC to bow
When the flexible circuit board is arched, it may further cause it to press against the adhesive tape above it, resulting in abnormal noise; in addition, the flexible circuit board may exceed the polarizer on the highest surface of the backlight module after arching. risk
When the integrated circuit board is fixed too loosely, the screws used to fix the integrated circuit board are easy to fall off

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0029] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiment of the present application, the directional indications are only used to explain the position in a certain posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, if there are descriptions involving "first", "second", etc. in ...

Abstract

The invention relates to the technical field of displays, and particularly discloses a backlight module and display equipment. The backlight module comprises a back plate, a support and an integrated circuit board; and the support is connected with the back plate, the support is provided with a groove, the integrated circuit board is installed in the groove, the groove is provided with an installation opening, and the projection of the installation opening on the integrated circuit board does not coincide with the projection of the back plate on the integrated circuit board. According to the technical scheme, the support is connected with the back plate, and the groove is formed in the support, so that the integrated circuit board can be well limited only by installing the integrated circuit board in the groove. Moreover, the installation process of fastening the integrated circuit board through a fastener is omitted, so that the installation process is simplified. The groove is provided with the installation opening, and the projection of the installation opening on the integrated circuit board does not coincide with the projection of the back plate on the integrated circuit board, so that the installation opening is prevented from being blocked by the back plate, and a user can conveniently and smoothly mount the integrated circuit board in the groove through the installation opening.

Description

technical field [0001] The present application relates to the technical field of displays, in particular to a backlight module and a display device using the backlight module. Background technique [0002] With the improvement of living standards, more and more display devices, such as televisions or computers, appear in people's lives. A display device is generally composed of a backlight module and a display panel. The backlight module is arranged behind the display panel to provide a light source for the display panel so that the display panel can display images. [0003] A traditional backlight module includes a backplane, an optical board, an optical film, a light source, an integrated circuit board, and a flexible circuit board. On the lug of the board, one end of the flexible circuit board is electrically connected to the integrated circuit board, and the other end is connected to the display panel. However, the traditional way of fixing the integrated circuit board...
