Abstract

The invention relates to a fixing structure for an optic diaphragm, which comprises a base board, a plurality of fixing elements on the base board, and a first diaphragm material on the base board. Wherein, the first diaphragm material has a first fixing hole and a second fixing hole that are located at the horizontal location on the upper side of the first diaphragm material and the second fixing hole is of a first angle with the horizontal direction, and the fixing elements respectively pass the first fixing hole and the second fixing hole correspondingly. By arranging fixing holes of the diaphragm materials and reserving holes for the moving position, the invention makes all diaphragm materials of different thermal expansion coefficients to move toward a preset direction, which eliminates any movement interference between diaphragm materials.

Description

technical field

[0001] The invention relates to an optical film material of a backlight module, in particular to a fixing structure of an optical film. Background technique

[0002] In view of the rapid development of thin-film transistor manufacturing technology, liquid crystal displays have been widely used in electronic product display devices, such as personal Consumer electronics or computer products such as digital assistants, portable TVs, mobile phones, camcorders, notebook computers, and desktop displays, but because LCDs are non-luminous display devices, they need backlight modules to produce displayed function.

[0003] The backlight module includes a light guide plate, a reflection plate, a light source, an optical film material composed of several layers of thin films and an aluminum back plate. The optical film is composed of several layers of films and is arranged on the upper surface of the light guide plate. These films include a lower diffuser, a prism, a...
