Problems solved by technology

[0005] However, the known plastic frame is integrally molded into a mouth-shaped body. Since the size of the plastic frame is fixed and there is no shared elasticity, it cannot be applied to products of other sizes. Furthermore, different sizes of products need to be opened with different molds. Making suitable plastic frames will result in high mold opening costs and material costs

Abstract

The invention relates to a backlight module and a rubber frame structure of the backlight module. The backlight module comprises a back panel, a light guide plate and the rubber frame structure, wherein the rubber frame structure is used for positioning the light guide plate and the back panel, and consists of two first frames and two second frames which are used for supporting four corners of the light guide plate; the first frame is combined with the back panel by a first positioning piece and a first combination piece; and the second frame is combined with the back panel by a plurality of second positioning pieces. According to the invention, by changing the rubber frame structure into a four-piece design and replacing the known integrated square rubber frame with four L-shaped corner rubber frames, the rubber frame structure is not only applicable to backlight modules with various sizes, but also can save the mold opening cost by utilizing the small volume of the rubber frame, save the material cost of the rubber frame due to minimization of materials required, so as to further achieve the purposes of reducing mold and finished product costs of the rubber frame.

Description

[0001] This application is a divisional application, the filing date of the original application is: January 15, 2010; the application number is: 201010003892.2; the invention name is: backlight module and its plastic frame structure technical field [0002] The invention relates to a fixing structure, in particular to a backlight module and its plastic frame structure. Background technique [0003] With the rapid progress and evolution of display technology, the traditional cathode ray tube (cathode ray tube, CRT) has been gradually eliminated due to problems such as poor space utilization and large energy consumption, and has been replaced by light, thin, short, small LCD (liquid crystal display, LCD). Due to the advantages of high display quality, low energy consumption and no radiation, liquid crystal displays are widely used in notebook computers, computer screens, mobile phones, personal digital assistants (PDAs), digital cameras, and digital cameras. And LCD TV and o...
