Backlight module and display with the same

Abstract

The invention provides a backlight module. The backlight module comprises an optical membrane, adhesive tape and a light guide plate. The optical membrane is arranged on one side of the light guide plate. One part of the adhesive tape adheres to the peripheral side wall of the light guide plate, and the other part of the adhesive tape adheres to the outer side of the optical membrane. The optical membrane is fixed to the light guide plate through the adhesive tape and is directly and stably fixed to the light guide plate through the adhesive tape, and therefore back plates, rubber frames and other parts in existing backlight modules are omitted, assembly gaps existing in the backlight module assembly process are eliminated, and the overall thickness of the backlight module is reduced. In addition, the backlight module is simple in structure, and therefore the manufacturing cost is reduced, the assembly process of the whole backlight module is more convenient and rapid, and the assembly efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of light-emitting displays, in particular to a backlight module and a display with the backlight module. Background technique [0002] With the continuous development of backlight display technology, liquid crystal display devices such as liquid crystal displays (Liquid Crystal Display, LCD) have been widely used as display components in electronic products such as mobile phones, digital cameras, and personal digital assistants (Personal Digital Assistant, PDA). As the bezels of electronic products become narrower and the technology of the liquid crystal industry continues to advance, the large size of LCD screen display and the thinning of bezels are increasingly becoming the mainstream demand of the market. [0003] As an important part of the liquid crystal display device, the backlight module has also become a trend in its frame design. The narrow frame means that the screen area that can be seen under the same si...

Problems solved by technology

[0004] However, during the assembly process, due to errors in the assembly process of the light guide plate and the plastic frame, it is inevitable that there will be an assembly gap between the light guide plate and the plastic frame, and because the plastic frame itself has a certain thickness, this is inevitable. It will increase the thickness of the backlight module, thereby increasing the overall thickness of the liquid crystal display device, which cannot meet the mainstream needs of the market.

In addition, the existing backlight module requires more components and complex structure, which increases the manufacturing cost; moreover, the assembly process of the plastic frame and the light guide plate is relatively cumbersome, and the assembly efficiency is low
