Problems solved by technology

[0002] In the prior art, the plastic-iron integrated backlight structure, based on the particularity of the structure, forms a closed groove after the plastic material and the steel sheet are integrally formed, and the light guide plate of the film material is placed in the groove, and the LCD is connected with the glue through the hole. After the glass is bonded and assembled, a completely enclosed space is formed. After special tests such as high temperature and high humidity, high temperature and high pressure, and low temperature, the membrane material in the groove will be arched, and the water vapor will not be able to dissipate. Quality problems such as product deformation, which in turn will lead to the shortcomings of poor reliability of the product

Embodiment 1

[0027] A rubber-iron integrated backlight structure that can avoid product failure after testing in this embodiment, such as Figure 1 to Figure 3 As shown, it includes an iron frame, a plastic frame covered with the iron frame and integrally formed with the iron frame; the plastic frame includes a first plastic frame body 1, and a second plastic frame body 2 arranged on the side of the first plastic frame body 1 ; The first plastic frame body 1 includes a first frame 11, a second frame 12, a third frame 13 and a fourth frame 14 which enclose a rectangular structure in turn; the second plastic frame body 2 is arranged on one side of the first frame 11; The second plastic frame body 2 is provided with a plurality of first ventilation holes 3 , and the first frame 11 is provided with a second ventilation hole 4 . Since the second plastic frame body 2 is provided with a number of first ventilation holes 3, and the first frame 11 is provided with a second ventilation hole 4, it ca...

Embodiment 2

[0033] An embodiment 2 of the rubber-iron integrated backlight structure of the present invention that can avoid product failure after testing. The difference between this embodiment and embodiment 1 is that in this embodiment, the second plastic frame body 2 is opened There are three first air holes 3, and the three first air holes 3 are evenly arranged on the second plastic frame body 2. The three first air holes 3 can effectively solve the problem of the plastic-iron integrated backlight structure and FOG assembled into a finished LCM. , After environmental tests (such as high temperature and high humidity, high temperature and high pressure or low temperature), problems such as membrane material arching, difficult moisture distribution and product deformation occur, thereby improving the reliability of LCM finished products. In this embodiment, the included angle between the first hole portion 41 and the second hole portion 42 is set to be 80 degrees. The angle between the...

Embodiment 3

[0035] Embodiment 3 of the rubber-iron integrated backlight structure of the present invention that can avoid product failure after testing. The difference between this embodiment and Embodiment 1 is that in this embodiment, the first hole 41 and the second hole The included angle between the two holes 42 is set to be 100 degrees. The angle between the first hole portion 41 and the second hole portion 42 can not only dissipate the water vapor, but also prevent the membrane material from arching and product deformation. Other structures and working principles of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of backlight modules, in particular to a rubber-iron integrated backlight structure capable of avoiding defective products generated after tests. The structure comprises an iron frame and a rubber frame which coats the iron frame and is integrated with the iron frame. The rubber frame comprises a first rubber frame body and a second rubber frame body arranged on the side of the first rubber frame body; the first rubber frame body comprises a first frame, a second frame, a third frame and a fourth frame which sequentially form a rectangular structure; the second rubber frame body is arranged on one side of the first frame; a plurality of first air holes are formed in the second rubber frame body, and second air holes are formed in the first frame. The rubber-iron integrated backlight structure can effectively solve the problems that after the rubber-iron integrated backlight structure and an FOG are assembled into an LCM finished product, membranes bulge, moisture is difficult to emit and products are deformed after environment tests (such as high-temperature and high-humidity tests, high-temperature and high-pressure tests and low-temperature tests), and then the reliability of the LCM finished products is improved.
