Abstract

The invention provides a backlight module which comprises a back plate (2), a light guide plate (4), a backlight source (6), a light shield (8) and a side reflecting piece (10). The light guide plate (4) is arranged inside the back plate (2). The backlight source (6) is arranged inside the back plate (2) and located on one side of the light guide plate (4). The light shield (8) is arranged between the backlight source (6) and the back plate (2). The side reflecting piece (10) is arranged between the light guide plate (4) and the backlight source (6). The backlight source (6) comprises an LED substrate (62) and a plurality of LED lamps (64) installed on the LED substrate (62). The side reflecting piece (10) has elasticity. The side reflecting piece (10) is provided with a plurality of openings (102) corresponding to the LED lamps (64). The LED lamps (64) are contained inside the openings (102) and provide a light source for the light guide plate (4).

Description

technical field [0001] The invention relates to the field of plane display, in particular to a backlight module. Background technique [0002] 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 (PDAs), digital cameras, computer screens or laptop 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 consists of a color filter substrate (Color Filter), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. Its working principle is to control the rotation of the liquid cry...
