Description
[technical field]
The present invention relates to field of display technology, and in particular to backlight module and using the backlight module as the display of light emitting source
Device.
[background technique]
There are two types of the down straight aphototropism mode sets of Organic Light Emitting Diode (light-emitting diode, LED) display
Common way of realization, one kind pasting type LED (LED unit for needing more number) to directly adopt surface, and second is table
Paste type LED collocation secondary lens (LED unit number can be reduced) in face.However, no matter which kind of way of realization used, diffuser plate is all
Need support construction prevent its due to it is cold and hot collapse, in transportational process vibrate caused by deformation, cause quality problem or
Person wounds LED unit (when housing depth is lower).
At present one of common practice for using supporting element (support pin) as the support construction of diffuser plate, one
As in the case of, supporting element is an individual module, needs individually to be designed and be opened according to demand, and individually carry out group
Dress, the number of strut demand of the bigger down straight aphototropism mode set of size is more, and assembling is time-consuming longer, and manpower consumption is bigger.
In addition, the fixed form of supporting element is generally adherent or buckle-type, and as shown in Figure 1, supporting element 120 and LED
Unit 110 sticks on backboard 101, and multiple supporting elements 120 are supported jointly on diffuser plate 130 and diffuser plate 130 above it
The diaphragm of side, in backlight use process or transportational process, because cavity temperature increases, supporting element 120 has degumming due to high temperature
Or it is detached from the risk of buckle, supporting element 120 once falls off, and the components such as diffuser plate 130 and diaphragm above will lose branch
Support, the height of entire cavity change, and lamp shadow, the quality problems such as shadow generate therewith, and the supporting element 120 to fall off is in cavity
In in not being bound state, easily cause various chain problems to occur.
Therefore, it is necessary to a kind of new technical solutions, to solve the problems, such as this.
