Description
Technical field
The invention relates to its liquid crystal indicator of a kind of backlight module and assemble method thereof and application, and particularly relevant for its liquid crystal indicator of a kind of backlight module of fast changeable light source module and assemble method thereof and application.
Background technology
Because liquid crystal indicator (Liquid Crystal Display Device, LCD Device) have volume frivolous, save characteristics such as space, low power consumption and low radiation pollution, replaced traditional cathode-ray tube (CRT) (Cathode Ray Tube in recent years gradually, CRT) display device, the standard that becomes computer of new generation is equipped with.And the backlight module in the liquid crystal indicator gives display panels in order to uniform light source to be provided, and presents beautiful abundant picture thus.
Please refer to Fig. 1, it illustrates is the fragmentary cross-sectional view of traditional liquid crystal indicator.Liquid crystal indicator 103 comprises housing 105, backlight module 100, the first Polarizer 142a, the second Polarizer 142b and display panels 150.Backlight module 100 comprises framework 110, backboard 120, fluorescent tube 130, diffusing panel 138 and blooming piece 140.Fluorescent tube 130 is disposed on the backboard 120, and diffusing panel 138 is disposed on the support portion 122 of backboard 120, and blooming piece 140 is disposed on the diffusing panel 138.See through the assembling of framework 110 and backboard 120, diffusing panel 138 and blooming piece 140 can be arranged in the backlight module 100.Wherein, the side plate 121 of framework 110 interfixes with the side plate 123 of backboard 120.The first Polarizer 142a places on the framework 110, and display panels 150 is disposed on the first Polarizer 142a.And the first Polarizer 142a and the second Polarizer 142b insert and put this display panels 150 up and down.Via the assembling of housing 105, the first Polarizer 142a, the second Polarizer 142b and display panels 150 can be arranged on the backlight module 100 with framework 110.
Yet above-described traditional backlight module 100 at first must be separated housing 105 and framework 110, to unload the first Polarizer 142a, the second Polarizer 142b and display panels 150 when changing fluorescent tube 130.Then, split-frame 110 and backboard 120 are to take out blooming piece 140 and diffusing panel 138.At last, could change the fluorescent tube that damages on the backboard 120.And fluorescent tube to be replaced finish must be according to the routine with all elements combination of above-mentioned liquid crystal indicator 103 to original state.In view of this, the step of the replacing fluorescent tube of traditional backlight module is not only loaded down with trivial details but also consuming time, does not very meet economic benefit.And in the process of the loading and unloading first Polarizer 142a, the second Polarizer 142b, display panels 150, blooming piece 140 and diffusing panel 138, cause the damage of these elements easily.The backlight module that is light source assembly as for other application light emitting diodes also can face above-mentioned problem.Therefore how to reduce step, the raising packaging efficiency of changing light source assembly and be one of important goal at present extremely to be solved in fact.
Summary of the invention
In view of this, purpose of the present invention is providing a kind of backlight module exactly, and its web member is connected separably with framework and backboard.Therefore when changing the light source assembly that damages, backboard need only be separated promptly replaceable new light sources assembly with web member.Diffusing panel and blooming piece must be do not unloaded earlier, with the replaceable light source assembly of ability after web member and the framework apart, diffusing panel and blooming piece can be avoided injuring again.Say that further web member connects backboard separably and framework has been simplified the step of replacing light source assembly and improved packaging efficiency.
According to purpose of the present invention, a kind of backlight module is proposed, comprise framework, backboard, at least one light source assembly and web member.Light source assembly is disposed on the backboard.Web member is connected separably with framework and backboard.
According to another object of the present invention, a kind of liquid crystal indicator is proposed, comprise display panels and backlight module, in order to the backlight of display panels to be provided.Backlight module comprises that framework, backboard reach light source assembly at least.Light source assembly is disposed on the backboard.Web member is connected separably with framework and backboard.
According to a further object of the present invention, a kind of assemble method of backlight module is proposed, may further comprise the steps.At first, provide backboard.Then, dispose at least one light source assembly on backboard.Then, the configuration web member is on this backboard, and web member connects backboard separably.Then, provide framework, framework is connected separably with web member.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and cooperate appended diagram, be described in detail below.
