Abstract

The invention provides a direct type LED backlight module, which comprises a back plate, a diffusion plate and a rubber frame, and is characterized in that: the opening end of the back plate is provided with a supporting platform; the rubber frame is arranged at the periphery of the supporting platform and fixed on the supporting platform; the diffusion plate is arranged on the supporting platform and fixed by the rubber frame; and the diffusion plate is supported by adjusting an area of a contact area between the diffusion plate and the supporting platform on the back plate and / or adhering the diffusion plate to the supporting platform. The invention also provides a television comprising the backlight module. By the backlight module and the television, problems that the volume of a bracket is increased, the bracket generates a shade in the backlight module and an optical diaphragm is arranged because the light mixing distance is increased are effectively avoided, and the cost of the whole television is obviously reduced.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a backlight module and a television set including the backlight module. Background technique [0002] At present, the backlight modules used in TV sets all include brackets, such as figure 1 and figure 2 As shown, among them, 1 is the backplane, 3 is the light source, 4 is the diffuser plate, 5 is the plastic frame, 9 is the bracket, in the backlight module of the direct type CCFL (Cold Cathode Fluorescent Lamp cold cathode fluorescent lamp tube), the bracket 9 It plays the role of supporting the diffuser plate 4 and fixing the CCFL light source 3; in the backlight module of the direct type LED (Light Emitting Diode), the bracket 9 only plays the role of supporting the diffuser plate 4 . [0003] For direct-lit LED backlight modules, in order to reduce the number of light sources 3 (that is, LED lamps), it is necessary to increase the light mixing distance of the backlight m...
