Because of the buffering component that can be arranged on the contact surface of the plane light or its supporting structure, there is a wider compression margin as assembling, able to reduce the rupture of the plane light caused by improper pressure as assembling, and then able to raise the yield of the backlight modules.
Description
Technical field
The present invention relates to a kind of plane lamp backlight protection structure, particularly a kind of plane lamp backlight protection structure that is used for LCD.
Background technology
The characteristics that LCD is thin because of possessing, in light weight, power consumption is low are used as flat-panel screens at wide model of information communication epoch, and its purposes enlarges just gradually, except the notebook personal computer of present main application, also be applied in aspects such as audiovisual appliances such as desktop display, TV and giant display.Generally speaking, because liquid crystal itself is non-luminescence component, so the display device of use liquid crystal panel must have backlight as light source.Backlight must possess following performance: must have the needed brightness of display frame, brightness uniformity, visual angle (penetrating light orientation angle), color rendering energy aspect optics; Requirement power consumption is low aspect electric property, noise is low; Aspect mechanicalness, require thin, in light weight, resistance to impact etc.
Please refer to Fig. 1, it is the plane modulated structure diagrammatic cross-section in the existing plane lamp backlight module.Plane lamp 11 in this plane lamp backlight module mainly is made up of upper glass plates 111, discharge space 112, lower glass plate 113 and glue frame 114.Wherein discharge space 112 is formed between upper glass plates 111 and the lower glass plate 113, thereby forms the pattern of three-decker.
In addition, Fig. 2 is the plane modulated structure diagrammatic cross-section in another existing plane lamp backlight module.Plane lamp 21 in this plane lamp backlight module mainly is made up of upper glass plates 211, discharge space 212 and lower glass plate 213.As shown in the figure, discharge space 212 is directly formed by upper glass plates 211 and lower glass plate 213, from outside pattern that to watch this plane lamp be double-layer structure.
Please refer to Fig. 3 again, it is the structural representation of existing plane lamp backlight module midplane lamp and the assembling of plane lamp bracing frame.Also comprise plane lamp bracing frame 31 in the plane lamp backlight module, behind the plane lamp 21 that completes, need to assemble with plane lamp bracing frame 31 again, general using screw 32 in the corner, limit or four corners fixed.Therefore exert pressure when the corner, limit of plane lamp 21 or four corners are often because of assembling and cause corner to chap even rupture.
As mentioned above, in plane lamp backlight, plane lamp and plane lamp bracing frame are in the corner, limit or four corners are fixed, so often exert pressure because of assembling or thermal stress cause four the corners be full of cracks or the fracture of plane lamp, so not only may cause plane lamp afunction, in reliability test, backlight module was lost efficacy.Therefore how to avoid that the plane lamp is under pressure in assembling and operating process, the destruction of stress and other impact energy is an important topic that improves the backlight module product percent of pass.
Summary of the invention
In view of the above problems, the purpose of this invention is to provide a kind of plane lamp backlight protection structure that the plane lamp is under pressure, stress and other impact energy are destroyed of avoiding in assembling and operating process.
For achieving the above object, plane lamp backlight protection structure of the present invention comprises planar light source, fixation kit and at least one Buffer Unit.Wherein planar light source is installed in the fixation kit and has at least one surface of contact, and Buffer Unit is arranged on this surface of contact.
As mentioned above, because of plane lamp backlight protection structure of the present invention is provided with Buffer Unit at the supporting construction place that cooperates with the plane lamp, so the destruction of taking place in the time of avoiding assembling by Buffer Unit, and can in operating process and reliability test, absorb thermal stress or other impact energy.Furthermore, because of plane lamp backlight protection structure of the present invention is provided with Buffer Unit, Buffer Unit can be installed on the surface of contact of plane lamp or its supporting construction, so have bigger compression nargin during assembling, improper the breaking of causing of exerting pressure when the plane lamp is assembled can be reduced, and then the qualification rate of backlight module can be improved.
