Abstract

An embodiment of the invention provides a backlight module and electronic equipment. The backlight module comprises a light source for supplying light for the backlight module, a light guide plate, a middle frame and a back plate, wherein a fluorescent film is adhered to the end face of the non-light-entering side of the light guide plate, adhesive tape is adhered to the inner wall of the middle frame, the guide plate adhered with the fluorescent film is assembled to a cavity formed by the middle frame and the back plate, and the fluorescent film is allowed to contact with the adhesive tape. By the arrangement, the formed white-light backlight module is free of blue light leakage and edge bright lines, high in color gamut, ultrathin, ultra-narrow in edge, and the like.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and electronic equipment. Background technique [0002] At present, the LCD screens of many smart terminals are equipped with backlight modules, such as figure 1 It is a commonly used combination of backlight modules. Such as figure 1 As shown in , generally, the blue light backlight module adopts a light guide plate equipped with a white end surface reflection or a silver end surface reflection, and the backlight module is arranged under the liquid crystal panel 101. White end reflector or silver end reflector 104 and plastic middle frame 105 . [0003] The inventor finds in the process of carrying out the application, such as figure 2 As shown, the traditional manufacturing method of the backlight module makes the edge of the light guide plate easy to form white bright lines and easy to leak blue light. The end face 201 is the light-incident side end f...
