Abstract

The invention relates to a backlight module comprising a light guide plate, an optical membrane material located on the bottom surface of the light guide plate, and a conductive metal plate which is used for electrically connecting a flexible circuit board of a display panel and is located on one side, far away from the optical membrane material, of the light guide plate. A display device is alsorelated to. The backlight module has the advantages that with the flexible circuit board in contact with the conductive metal plate, good grounding effect is achieved; with the flexible circuit boardfixed on the conductive metal plate, the connection stability of the flexible circuit board is improved, the capacitive sound transmitted by the flexible circuit board is greatly reduced, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of display product production, in particular to a backlight module and a display device. Background technique [0002] Full-screen mobile phones have stunning visual impact and visual experience, and are favored by major mobile phone manufacturers. Full-screen mobile phones have become the development trend of mobile phones. A full-screen mobile phone refers to a mobile phone with a high screen-to-body ratio, the screen-to-body ratio can reach more than 85%, and a mobile phone with an ultra-narrow bezel design, generally with a screen aspect ratio of 18:9 or 18.5:9. When the full screen adopts LCD (LiquidCrystal Display, liquid crystal display) plastic frame backlight module to provide brightness, such as figure 1 As shown, 101 is the reflective film of the backlight module, 102 is the exposed copper area of ​​the flexible circuit board, 103 is the conductive cloth, 104 is the composite film, and 105 is the...
