Embodiment Construction

[0026] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0027] In the backlight module according to the embodiment of the present invention, the other edge of the light bar is arranged on the optical film, and the first optical film and the second optical film among the at least three optical films are respectively fixedly connected to a fixing component, In order to ensure the fixation of the optical film on the other edge of the light bar, the shrinkage direction of the optical film is from one side of the light bar to the opposite side, so as to reduce the bright line of the optical film on the opposite side of the light bar due to shrinkage deformation probability.

Abstract

The invention provides a backlight module group and a display device. The backlight module group comprises a light bar, a fixed assembly, and at least three optical membranes stacked successively. Thelight bar is arranged along the first edge of the optical membrane. The first optical membrane and the second optical membrane among the at least three optical membranes are fixedly connected with the fixed assembly at the second edge of the optical membrane. The distance between the first optical membrane and the third optical membrane is the largest and the second optical membrane and the thirdoptical membrane are in contact and are connected among the at least three optical membranes; and the second edge and the first edge are different. According to the backlight module group, the contraction direction of the second optical membrane is from one side of the light bar to the other side of the light bar and thus the overall contraction amount of the other opposite edge of the edge withthe light bar is reduced, so that the effect of improving the bright light of the tail is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] With the structural development of electronic equipment, narrow bezels and full screens have become the development trend of display screens on current electronic equipment. In order to increase the screen-to-body ratio of the display screen, the frame of the display screen is getting narrower and narrower. However, based on this development trend, the problem of bright lines at the rear frequently occurs. [0003] At present, the problem of bright lines at the tail of the display screen is greatly affected by factors such as the size of the film material, assembly accuracy, and shrinkage of the film material after the environmental reliability test, but a large proportion of the problem of bright lines at the tail is due to the distance between the lower prism and the plastic frame. Larger cause. [0004] ...
