[0018] The following describes the backlight module provided by the present invention in combination with icons:
[0019] See figure 2 The backlight module provided by the present invention includes a flat cold cathode lamp 30 and a light guide plate 20. The light guide plate 20 can be flat or wedge-shaped, and its shape is not limited. It includes a light incident surface 21, A light exit surface 23 and a reflective surface 22 opposite to the light exit surface. V-shaped grooves are formed on the reflective surface 22 and the light exit surface 23; the cold cathode lamp 30 is located on the light entrance surface 21 side of the light guide plate 20, wherein the A nano-scale silica particle layer 32 is formed on the surface of the tube 31 of the cold cathode lamp 30.
[0020] The cold cathode lamp 30 is designed to be flat so that it is close to a surface light source, which is beneficial to improve the uniformity of the backlight source.
[0021] A V-shaped groove is formed on th...
