Abstract

The invention provides a backlight module. The backlight module comprises a rubber frame, a light guide plate, a light-reflecting sheet, a lamp source and an optical film, wherein the optical film and the light guide plate are sequentially overlapped on the light-reflecting sheet; the rubber frame is wound around the peripheries of the light-reflecting sheet, the light guide plate and the optical film; the backlight module also comprises a radiating plate; the lamp source comprises a lamp strip circuit board and a light-emitting body and is positioned between the light-incidence surface of the light guide plate and the rubber frame; the light-reflecting sheet and the lamp strip circuit board are arranged on the radiating plate and are positioned on the same plane; a part of the lamp strip circuit board is clamped by the light guide plate and the radiating plate. The invention also discloses a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a display. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as mobile phones, personal digital assistants (PDA), digital cameras, computer screens or notebook computer screens Wait. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. The structure of a traditional liquid crystal panel is composed of a color filter substrate (Color Filter), a thin film transistor array substrate (Thin Film TransistorArray Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. ...
