Abstract

The invention discloses a direct type backlight module and a display terminal. The backlight module comprises a lamp panel and a rear panel, wherein LED (Light Emitting Diode) lamps, which are distributed in an array, are arranged on a first surface of the lamp panel; cabling terminals and/or lamp panel driving modules of the LED lamps are arranged on a second surface of the lamp panel; the LED lamps are electrically connected with the cabling terminals and the lamp board driving modules; the cabling terminals are used for outward electric connection; the rear panel is located at the side of the second surface of the lamp panel; the rear panel is provided with an avoiding structure; the cabling terminals and the lamp panel driving modules are located in the avoiding structure. According tothe direct type backlight module disclosed by the invention, the cabling terminals and the lamp panel driving modules are arranged on one surface of the lamp panel and are stored in the avoiding structure of the rear panel, so that the LED lamps and the cabling terminals and/or the lamp panel driving modules are integrated and the area ratio of a function panel on the rear panel is reduced so that the appearance region of the rear panel is enlarged; the rear panel can be used as a rear shell, so that the thickness of the backlight module is greatly reduced and a television is thinned.

Description

technical field [0001] The present application relates to the technical field of liquid crystal televisions, in particular to a direct-lit backlight module and a display terminal. Background technique [0002] LCD TVs are widely used because of their wide color gamut, long service life, environmental protection and energy saving, and ultra-thin appearance. Due to the wide use of LCD TVs, the competition among various businesses is becoming more and more fierce. The pursuit of ultra-thin appearance has become a means of competition for various businesses. . [0003] Such as figure 1 It is a structural schematic diagram of an existing direct-lit LCD TV. A traditional direct-lit LCD TV includes a backlight module, a liquid crystal panel 70 arranged in the light emitting direction of the backlight module, and a plastic frame 60 and a front frame for sandwiching the liquid crystal panel 70 80. The backlight module includes a backplane 1, a reflector 30, a diffusion plate 40, a ...
