Description
Technical field
The invention relates to a kind of liquid crystal display device module and assembling thereof and disassembling method, and particularly relevant for a kind of liquid crystal display device module and assembling and the disassembling method that can directly change backlight module.
Background technology
In order to cooperate modern life pattern, it is frivolous that the volume of video signal or device for image day by day is tending towards.Traditional cathode-ray tube (CRT) though still have its advantage, because the structure in internal electron chamber, makes that display is bulky and takes up space, and still has radiant rays to hinder problems such as eye when showing.Therefore, the plane formula display (FlatPanelDisplay) that cooperates photoelectric technology and semiconductor fabrication to be developed, for example LCD (LCD), organic light emitting display (OLED) or plasma display panel (PlasmaDisplayPanel, PDP), become the main flow of display product gradually.
From the above, the vigorous growth in recent years of its product of LCD, and that the kind of product also tends to is various.In addition, with regard to LCD, its light source utilizes kenel can slightly be divided into three kinds of reflective liquid-crystal display (ReflectiveLCD), penetrating LCD (TransmissiveLCD) and semi-penetrated semi-reflected liquid crystal displays.With the penetration or the LCD of semi-penetration, semi-reflective is example, it is made of a liquid crystal panel and a backlight module, wherein, liquid crystal panel is made of the liquid crystal layer that two transparency carriers and are disposed between this two transparency carrier, and backlight module is in order to provide this liquid crystal panel required area source, so that LCD reaches the effect of demonstration.
Fig. 1 illustrates the diagrammatic cross-section of known a kind of liquid crystal display device module.Please refer to Fig. 1, liquid crystal display device module 100 is made of a backlight module (backlightmodule) 110, a framework 120, a liquid crystal panel 130 and a chase 140.Wherein, backlight module 110 is the belows that are disposed at liquid crystal panel 130, and backlight module 110 is made of a light guide plate (lightguideplate) 112, a light source 114 and a light source holder 116.Above-mentioned light guide plate 112 for example is a wedge shape light guide plate, and it has a light entrance face 112a, a smooth diffusingsurface 112b and a light-emitting face 112c.Light source holder 116 is disposed at by the light entrance face 112a, and light source 114 then is disposed in the light source holder 116.Backlight module 110 is except having above-mentioned member, and it can also have a reflecting plate 118, and this reflecting plate 118 for example is configured between the light diffusingsurface 112b and framework 120 of light guide plate 112.Framework 120 is made of upper frame 122 and underframe 124, and therefore its function can fix the relative position between light guide plate 112, light source 114 and the light source holder 116 in order to coat above-mentioned backlight module 110, produces the phenomenon that moves to reduce.
Please equally with reference to Fig. 1, liquid crystal panel 130 is to be positioned at backlight module 110 tops, and liquid crystal panel 130 is to be bearing on the upper frame 122.For example can dispose at least one blooming piece 150 between backlight module 110 and liquid crystal panel 130, the light that its function is penetrated by light-emitting face 112c in order to the light that increases light source 114 is to promote the homogeneity of its light.Chase 140 coats upper frame 122, underframe 124 and liquid crystal panel 130.
From the above, the light that light source 114 is provided can be incident in the light guide plate 112 by light entrance face 112a, and after the scattering and reflection through light diffusingsurface 112b, is passed to light-emitting face 112c and penetrates.From as can be known above-mentioned, the light that is penetrated by light-emitting face 112c is the kenel of the area source of white, in order to show required light source as liquid crystal panel 120.
It should be noted that, because its assembling mode of known liquid crystal display device module all is with each member assembling piecemeal, for example in regular turn reflector plate, light guide plate, light source, light source holder, optics matrix are positioned in the underframe, again with upper frame and underframe assembling, afterwards liquid crystal panel is placed on the upper frame, by chase its upper frame, underframe and liquid crystal panel are coated again at last, and be one with its locking with locking components such as screws.Therefore, if damaging appears in light source, light guide plate in the backlight module or reflecting plate or during aging phenomenon, be bound to again according in contrast to original order each member being disassembled one by one, just can reach the purpose that element upgrades.From the above, so liquid crystal display device module design will make LCD assembling with disassemble quite time-consuming and efficient not good.
