Description
Technical field
The present invention relates to the liquid crystal indicator of a kind of module backlight and this module backlight of employing, especially refer to a kind of liquid crystal indicator that is used for the down straight aphototropism mode set of large scale liquid crystal display device and adopts this module backlight.
Background technology
Because the liquid crystal itself in the panel of LCD is not luminous, thereby, for reaching display effect, a planar light source device is provided must for the LCD panel, as module backlight, to realize Presentation Function.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 display applications field, the particularly application of large scale liquid crystal display, as LCD TV etc., emitting brightness to the backlight liquid crystal display module 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.
Seeing also Fig. 1, is a kind of synoptic diagram of prior art down straight aphototropism mode set.This module 10 backlight comprises a framework 15, a plurality of light source 14, a diffuser plate 11 and a reflecting plate 12, and this reflecting plate 12, a plurality of light source 14 and a diffuser plate 11 are housed in this framework 15 from bottom to top successively.The light that this light source 14 sends after be sent to the liquid crystal panel that is provided with towards module 10 backlight by diffuser plate 11, makes liquid crystal panel obtain preferable brightness directly or through reflecting plate 12 reflections.
Yet, owing to have than large tracts of land in the middle of the diffuser plate 11 and be suspended on light source 14 tops, when the size of liquid crystal indicator is increasing, the size of diffuser plate 11 also can become big relatively in the module 10 backlight, because diffuser plate 11 has larger volume and weight, in installation process, be subjected to the relation of its deadweight very easily and cause distortion or sagging, in addition, also cause the distortion of diffuser plate 11 under the temperature that light source 14 is produced and the influence of its ambient humidity, light and temperature quite easily, thereby make module 10 optical characteristics variation backlight, and then the display effect of image liquid crystal indicator.
General common solution is to increase support component 27 (as shown in Figure 2) between diffuser plate and reflecting plate, these support component 27 1 ends are fixed in framework 25, one end props up diffuser plate 21 to keep diffuser plate 21 in the precalculated position, avoid diffuser plate 21 flexural deformations, improve the optical characteristics of module backlight.Yet because the assembling between diffuser plate 21 and the framework 25 has a tolerance clearance usually, therefore, when module backlight is given a shock or impacts or diffuser plate 21 in the process of rising-heat contracting-cold, also can and support component 27 between produce the mutual motion be parallel to the diffuser plate direction, and because of phase mutual friction each other causes soft flocks and different sound, and further cause module 10 optical characteristics variation backlight.
