Problems solved by technology

[0002] In existing display devices, the optical film material is easily wrinkled due to thermal expansion and contraction, resulting in uneven brightness and darkness.
Especially in large-size display modules, due to the large area of ​​the diaphragm, the required expansion space is also large. In order to take into account the screen-to-body ratio, the expansion of the diaphragm is often limited by the space, resulting in the undesirable phenomenon of diaphragm wrinkles
[0003] It can be seen that the existing display device has the technical problems of bad film folds and low display quality

Abstract

The invention provides a backlight module, a manufacturing method thereof and a display device. The backlight module comprises a first optical element, and a circle of fixing frame which is arranged around the first optical element and comprises a first frame and a second frame oppositely arranged, and a third frame and a fourth frame oppositely arranged. The side, facing the first optical element, of each border of the fixing frame is provided with a plurality of adhesive tapes which are independent of one another and extend in the extension direction of the edge, and the first optical element is fixed to the fixing frame through the adhesive tapes. The method is used for avoiding poor diaphragm wrinkling and improving the display quality.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] In the existing display device, the optical film material is easily wrinkled due to heat expansion and contraction, and then uneven brightness and darkness appear. Especially in large-size display modules, due to the large area of ​​the diaphragm, the required expansion space is also large. In order to take into account the screen-to-body ratio, the expansion of the diaphragm is often limited by the space, resulting in the undesirable phenomenon of diaphragm wrinkles. [0003] It can be seen that the existing display device has the technical problems of poor film folds and low display quality. Contents of the invention [0004] The disclosure provides a backlight module, a manufacturing method thereof and a display device, which are used for avoiding film wrinkle d...
