Abstract

The invention discloses a fixing device, a backlight source and a display device. The fixing device comprises a hook, a connector and a fixed end, wherein the hook is connected with the fixed end by the connector. By adopting the fixing device, the backlight source and the display device, the flatness of a sheet-shaped material can be kept; moreover, a backlight source membrane material is symmetrically and uniformly stressed in each direction, a flat state is kept better and wrinkles are avoided being generated; the brightness of the display device is uniform, the phenomenon of nonuniform brightness cannot be generated, and the fixing device, the backlight source and the display device have excellent and stable quality.

Description

technical field [0001] The invention relates to a fixing technology, in particular to a fixing device, a backlight source and a display device for thin sheet materials. Background technique [0002] In production and daily life, flake materials are used in many places, such as bottom reflective film materials used in liquid crystal display (Liquid Crystal Display, LCD) backlight. Sheet-like materials should remain flat during use. [0003] For the bottom reflection film of LCD backlight, hereinafter referred to as the backlight film, especially the super-large size, such as the size of the backlight film is greater than or equal to 84 inches, when the backlight film is fixed, Due to the excessive gravity of the backlight film material, thermal expansion and contraction, local uneven heating, deviation of positioning and matching accuracy, etc., it is easy to cause wrinkles of the backlight film material, resulting in light and dark phenomena in the LCD display process.
