Description
Technical field
The utility model relates to technical field of liquid crystal display, refers to a kind of magnetic backlight supporting construction especially.
Background technology
Liquid crystal display (LCD) has that volume is thin, lightweight, power consumption is few and the characteristic such as radiationless pollution, has now been widely used on the electronic products such as monitor, notebook computer, digital camera and projector.And liquid crystal itself can't be luminous, therefore need the backlight that backlight module provides evenly sufficient.
The backlight of backlight module is mainly based on light emitting diode.Light emitting diode is because compared with cold cathode fluorescent lamp, and its colour gamut is wider, light source is faster, liquid crystal display can be helped to eliminate de-tail phenomenon, not mercurous and longer than cold-cathode lamp tube lifetime, become current main development direction gradually.
Light emitting diode is a kind of semiconducting solid luminescent device, utilize solid semiconductor chip as luminescent material, semi-conductor chip is made up of P-type semiconductor and N-type semiconductor, these two kinds of semiconductors are coupled together, when electric current acts on this chip by wire time, can send energy with the form of photon, this is the principle of luminosity of light emitting diode.But light emitting diode also has luminescence efficiency low at present, and briliancy, the colourity of crystal are wayward, and unit price cost is higher etc., and problem exists.
Along with the lifting of liquid crystal display manufacturing technology, under the trend of large scale and low price, backlight module is in the market demands considering lightweight, slimming, low power consumption, high brightness and reduce costs, and for remaining on the competitive power of future market, the design of novel backlight module is an important topic.
The backlight of backlight module is all provided with bracing frame.The bracing frame of prior art makes with cast iron or plastics, and in order to support fixing backlight, need fix when assembling by bolt interlocking or some glutinous agent materials, this mode comparatively bothers and not easily detachable maintaining.And in backlight, because light emitting diode has above-mentioned various shortcoming in the characteristics of luminescence, no matter in the guiding of light, diffusion, or in service efficiency, have and need improvements.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of magnetic backlight supporting construction, the luminescence unit fixed frame that it provides, make the assembling that LCD display device energy is fast and convenient, and firm locating effect is provided, and the characteristics of luminescence of semiconductor light emitting unit can be regulated simultaneously by magnetic.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of magnetic backlight supporting construction, comprise: semiconductor luminescence unit module, in order to provide backlight to display panel, multiple semiconductor light emitting unit that described semiconductor light emitting unit module includes a substrate and lays on the substrate, each semiconductor light emitting unit described is the luminescence unit with a cathode terminal and anode tap adopting semiconductor material to make; One luminescence unit fixed frame, it has a locating slot structure, and embed location for described semiconductor light emitting unit module, described luminescence unit fixed frame is made up of magnetic material.
The substrate bottom surface of described semiconductor light emitting unit module is formed with at least one magnetic material layer.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, luminescence unit fixed frame of the present utility model because having magnetic, when assembling with housing can magnetic absorption on housing, assisted by the location structure of housing again, reach firm location, without using the add-on assemble such as bolt or glutinous agent material, more easy during dismounting maintenance.And luminescence unit fixed frame has a locating slot structure, make semiconductor light emitting unit module simply can embed location, and be formed with magnetic material layer in the substrate bottom surface of semiconductor light emitting unit module, make it more magnetic and luminescence unit fixed frame can be borrowed to adsorb fixing, strengthen overall locating effect.In addition, the magnetic field that luminescence unit fixed frame has, the light transfer characteristic of the effect adjustable semiconductor light emitting unit inner semiconductive material of magnetic, makes the divergence of beam angle of semiconductor light emitting unit produce and changes, become and more disperse or collect.Therefore, structural design and the backlight demand of different backlight module can be coordinated in actual applications, light regulating dispersion angle is carried out to required field of illumination by change magnetic field field pattern and magnetic field intensity, the light that semiconductor light emitting unit is sent is more efficient in use, saves component count and power consumption.No matter be utilize magnetic force to make assembling more convenient or in order to light regulating, because not needing other device of additional, not only there is no the problem that volume increases, also can because alleviating the burden of other assembly at light regulating, thus simplify overall structure, become gentlier, thinner, also therefore can save cost.
