Reflecting film, backlight module provided with same and display device provided with same

Abstract

The invention provides a reflecting film, a backlight module provided with the same and a display device provided with the same. The reflecting film is provided with at least two types of reflectivity, the reflectivity of a first region of the reflecting film is first reflectivity, the reflectivity of a second region of the reflecting film is second reflectivity, and the first reflectivity is smaller than the second reflectivity. The backlight module comprises the reflecting film, a light guide plate and a light source, wherein the light guide plate is provided with four lateral faces, a first lateral face is a light incidence face, a second lateral face and a third lateral face are respectively adjacent to the first lateral face, and a fourth lateral face is opposite to the first lateral face. The light source is arranged at the first lateral face end. The reflecting film is adhered to the second lateral face and the third lateral face, the reflectivity of the reflecting film close to the light source position is the first reflectivity, the reflectivity of the reflecting film away from the light source position is the second reflectivity, and the first reflectivity is smaller than the second reflectivity. The purpose of solving the problem that the luminance of the side of a light guide plate is uneven is achieved through the reflecting film with at least two types of reflectivity.

Description

Technical field [0001] The invention relates to a reflective film, a backlight module and a display device with the reflective film, and more particularly to a reflective film with different reflectivities, a backlight module and a display device with the reflective film. Background technique [0002] At present, in order to prevent light leakage from the side of the light guide plate, it is often necessary to attach a reflective film to the side of the light guide plate, such as figure 1 As shown, it is a schematic diagram of the structure of the prior art backlight module without a reflective film, 10 is a light guide plate, 20 is a circuit board on which an LED 30 is arranged, and the circuit board 20 and the LED 30 are arranged on a side of the light guide plate 10. On the side, the light guide plate further has a first side surface 11, a second side surface 12, and a third side surface 13, and a groove 131 is provided on the third side surface 13, and the groove 131 is used f...
