Description

Backlight module and liquid crystal display device
Technical field
The present invention relates to field of display technology more particularly to a kind of backlight modules and liquid crystal display device.
Background technique
With the development of display technology, the planes such as liquid crystal display (Liquid Crystal Display, LCD) display dress It sets because having many advantages, such as that high image quality, power saving, fuselage is thin and has a wide range of application, and is widely used in mobile phone, TV, a number The various consumer electrical products such as word assistant, digital camera, laptop, desktop computer, become the master in display device Stream.
Liquid crystal display device on existing market is largely backlight liquid crystal display device comprising liquid crystal display panel and back Optical mode group (backlight module).The working principle of liquid crystal display panel is to place liquid crystal in the parallel glass substrate of two panels Molecule, there are many tiny electric wires vertically and horizontally for two panels glass substrate centre, change whether by being powered to control liquid crystal molecule It changes direction, the light refraction of backlight module is come out and generates picture.
Since liquid crystal display panel itself does not shine, need the light source provided by backlight module normally to show image, therefore, Backlight module becomes one of the key component of liquid crystal display device.Backlight module is divided into side according to the difference of light source incidence position and enters Formula backlight module with two kinds of down straight aphototropism mode set.Down straight aphototropism mode set is by backlight such as cathodouminescence fluorescent tube (Cold Cathode Fluorescent Lamp, CCFL) or the setting of light emitting diode (Light Emitting Diode, LED) light source At liquid crystal display panel rear, light forms area source after diffusion sheet homogenizes and is supplied to liquid crystal display panel.
Referring to Fig. 1, being a kind of existing structural schematic diagram of down straight aphototropism mode set, which includes Backboard 100, center 200, light source 300, reflector plate 400 and diffusion sheet 500, the backboard 100 is including bottom plate 110 and is connected to bottom plate 110 edges and first side plate 120 vertical with bottom plate 110, the center 200 include the support plate of the second side plate 210, frame-shaped 220 and third side plate 230, the second side plate 210 is located at 120 outside of the first side plate, support plate 220 be located on the first side plate 210 and Its outer edge is connect with the inner sidewall of the second side plate 210, and support plate 220 is vertical with the second side plate 120, and third side plate 230 connects In support plate 220 inward flange and to close to bottom plate 110 direction extend, between third side plate 230 and the second side plate 210 away from It is gradually increased from along the direction close to bottom plate 110.Reflector plate 400 is set on bottom plate 110 and is located at bottom plate 110 and third side plate 230 between the edge of bottom plate 230, and reflector plate 400 has opening 410, and light source 300 is set on bottom plate 110 and corresponding reflection The opening 410 of piece 400 is arranged, and the upper and support plate 220 that diffusion sheet 500 is set to light source 300, reflector plate 400 and support plate 220 connects Touching.Existing center 200 be required to it is reflective, therefore material be typically chosen opaque white polycarbonate (PC) addition glass Fiber (GF) is made, therefore less in the light that the position that diffusion sheet 500 is contacted with the support plate 220 of center 200 can reach, Shadow is caused in this region, so that dark frame or dark side occurs in the liquid crystal display device surrounding with the backlight module, influences product Quality.
