Embodiment Construction

[0026] The technical problem solved by the present invention stems from the discovery that the multiple optical films contained in the backlight module are usually only stacked in sequence and pressed tightly in the plastic frame of the backlight module, and only one layer of adhesive tape is adhered to the top of the backlight module. Fixed, this method cannot effectively fix the optical films of each layer, resulting in the risk of shifting the lower layer of the film during use. The optical film is thin, and each optical film may shift during use, while the optical film The optical characteristics should be considered between the sheets, so more glue cannot be inserted between the films. The present invention designs the structural design and bonding method of the glue based on the discovery of such problems. See the following backlight module embodiment for details.

[0027] see figure 2 , the embodiment of the present invention provides a backlight module 200 , which inc...

Abstract

The invention provides a backlight module which comprises a plurality of optical films and further comprises multiple layers of colloid sequentially overlapped. Each layer of colloid is attached to one optical film so that all the optical films can be fixed. The invention further provides a liquid crystal display device using the backlight module, and a preparing method of the backlight module. The preparing method of the backlight module includes the steps of overlapping the optical films, overlapping the multiple layers of colloid, and attaching the overlapped colloid to the optical films. According to the backlight module, the multiple layers of colloid are overlapped to be attached to the optical films of different layers, the process is simple, the optical films are good in attachmentfixity, and optical performance of the optical films is not affected.

Description

technical field [0001] The invention relates to the field of backlight module preparation, in particular to the preparation of optical film glue for the backlight module, a backlight module and a liquid crystal display device using the glue. Background technique [0002] The backlight module and the light source are widely used as backlight in mobile phones, computers, various instruments and other equipment with liquid crystal display. The backlight module usually includes multiple optical films, light guide plates, reflectors and so on. Multiple optical films are thin and stacked on the light guide plate and reflector, such as figure 1 As shown, a plurality of stacked optical films 10 are usually only fixed in the plastic frame 14 by adhering a layer of adhesive tape 12 on the top, but this method cannot effectively fix the optical films 10 of each layer, resulting in relatively The underlying diaphragm is at risk of deflection during use.
