Background technique
In recent years, liquid crystal display has obtained answering extensively since its is light-weight, slim body and the excellent characteristics such as low in energy consumption
With.For example, computer, mobile phone, business automation equipment, audio/video device, indoor/outdoor show that equipment etc. is widely used
Liquid crystal display.
Since the liquid crystal material of liquid crystal display panel itself does not have the characteristics of luminescence in liquid crystal display, in order to
Reach display effect, light supply apparatus, such as backlight module need to be provided to liquid crystal display panel, function is to liquid crystal display panel
The irradiation light for providing luminance sufficiently and being evenly distributed.Backlight liquid crystal display controls the electric field for being applied to liquid crystal layer
System, and the light from backlight module is modulated, thus show image.
In general, backlight module includes straight-down negative (direct-type) backlight module and side type (edge-type) backlight mould
Group.Down straight aphototropism mode set is provided with multiple light sources on the lower surface of diffusing panel, and the light from these light sources advances to liquid crystal
The back side of display panel.Side backlight mould group include light guide plate side multiple light sources relative to each other are set, and including
Multiple optical sheets between liquid crystal display panel and light guide plate are set, and light guide plate is by the line light from light source or puts light
Planar light is converted to, which advances to the back side of liquid crystal display panel via optical sheet.
In the liquid crystal display using down straight aphototropism mode set, because of the light source wide dispersion of down straight aphototropism mode set
In the lower section of liquid crystal display panel, so luminance is excellent and light distribution is uniform.Down straight aphototropism mode set is according to its structure and performance, and one
As be used on large-scale liquid crystal display more.
For down straight aphototropism mode set (for ease of description, hereinafter referred to as " backlight module "), in its processing procedure,
Manually, multiple light sources are successively attached into backboard manually using double-sided adhesive, it is then using screw that reflector is tight manually
Gu on the backboard for being pasted with multiple light sources.In this way, not only increase cost of labor, but also low efficiency, quality are not easy to manage,
Therefore there is an urgent need to develop a set of line production system for backlight module manufacture.
