Description
Technical field
The present invention relates to the liquid crystal indicator of a kind of module backlight and this module backlight of employing.
Background technology
Because the liquid crystal of liquid crystal panel itself is not luminous in the liquid crystal indicator, thereby, for reaching display effect, need provide a planar light source device, as module backlight, to realize Presentation Function to display panels.Module backlight is divided into side-light type module backlight and down straight aphototropism mode set by structure.
Continuous expansion along with the liquid crystal indicator application, the particularly application of large scale liquid crystal display device, as LCD TV etc., emitting brightness to the module backlight of liquid crystal indicator requires further to improve, need to use a plurality of light-emitting components to improve the emitting brightness of entire aphototropism mould, traditional side-light type module backlight can not satisfy the requirement of its emitting brightness, so down straight aphototropism mode set becomes the main flow of large scale liquid crystal display device.
Seeing also Fig. 1, is a kind of side schematic view of prior art down straight aphototropism mode set.This down straight aphototropism mode set 1 comprises a diffuser plate 11, a plurality of line source 12 and a reflecting plate 13.This reflecting plate 13 is a tabular.This line source 12 is arranged between diffuser plate 11 and the reflecting plate 13, and it is a cathode fluorescent tube.The light that this line source 12 sends after transfer to the display panels (figure does not show) that contiguous down straight aphototropism mode set 1 is provided with by diffuser plate 11, makes display panels obtain preferable brightness directly or through reflecting plate 13 reflections.
Yet when the size of liquid crystal indicator was big more, the size of line source 12 also can become greatly relatively in the down straight aphototropism mode set 1, the quite big and fracture easily of the deflection that causes line source 12 under vibrational state.In addition, because line source 12 heatings, the also corresponding rising of this down straight aphototropism mode set 1 temperature inside easily makes this diffuser plate 11 that the dehydration phenomenon takes place because of the surface is heated buckling deformation takes place, and makes the optical characteristics variation of down straight aphototropism mode set 1.
For addressing the above problem, industry generally increases by a supporting construction between diffuser plate and reflecting plate.See also Fig. 2 and Fig. 3, Fig. 2 is the side schematic view of another kind of prior art down straight aphototropism mode set, and Fig. 3 is the three-dimensional enlarged diagram of the support member of down straight aphototropism mode set shown in Figure 2.This down straight aphototropism mode set 2 comprises a diffuser plate 21, a plurality of line source 22, a reflecting plate 23, a plurality of support member 24 and a metal backing 25.This metal backing 25 is accommodated this diffuser plate 21, these a plurality of line sources 22, this reflecting plate 23 and this a plurality of support members 24.This support member 24 is sandwiched between reflecting plate 23 and the diffuser plate 21, and the two ends of this line source 22 are immobilizated in this metal backing 25 by fluorescent tube retaining piece (not indicating) in addition, and line source 22 middle parts are supported to prevent flexural deformation by support member 24.
This support member 24 comprises a fixed part (figure does not show), a support portion 242 and two support bars 243.This support portion 242 is a conical cylinder, and its vertex of a cone and this diffuser plate 21 butts are used to support this diffuser plate 21.This fixed part is arranged at the bottom of this support portion 242, and it can snap in reflector plate 23 and the metal backing 25 corresponding accepting grooves (figure does not show) to fix this support member 24.This support bar 243 is gone out by the cone side horizontal expansion of this support portion 242, at least one supporter 246 is set, in order to support this line source 22 on each support bar 243.This fixed part, support portion 242 and support bar 243 are integrated formed structures.
Yet, because this support member 24 is integrated formed structures, in case after these support member 24 moulding, it only can be used for the liquid crystal indicator of a few even single size.The size of the line source 22 that it supported is relative fixed also, if will support the liquid crystal indicator of other size, then wants the supporter 24 of other size.To sum up, this support member 24 is lower with the versatility of the module backlight that uses it.
Summary of the invention
In order to solve the not high problem of prior art module versatility backlight, be necessary the module backlight that provides a kind of versatility higher.
In addition, also be necessary to provide a kind of liquid crystal indicator that adopts above-mentioned module backlight.
A kind of down straight aphototropism mode set, it comprises at least one fluorescent tube and at least one support member.Each support member comprises the holding parts that a fixed part, is used to support the support portion of diffuser plate and is used to support this fluorescent tube, this holding parts comprises a fixing arm and at least one supporter that is arranged on this fixing arm, this fluorescent tube of this support body supports, this support portion, fixed part and fixing arm are separable independent parts, and support portion and fixing arm are fixed on the fixed part, by being combined into one.
A kind of liquid crystal indicator, it comprises that a display panels and provides the down straight aphototropism mode set of planar light for this display panels.This down straight aphototropism mode set comprises at least one fluorescent tube and at least one support member.Each support member comprises the holding parts that a fixed part, is used to support the support portion of diffuser plate and is used to support this fluorescent tube, this holding parts comprises a fixing arm and at least one supporter that is arranged on this fixing arm, this fluorescent tube of this support body supports, this support portion, fixed part and fixing arm are separable independent parts, and support portion and fixing arm are fixed on the fixed part, by being combined into one.
