  • Display device with flexible circuit board extended to be interposed between light guiding film buttons and display panel
    Patent number: 10042460
    Abstract: A display device, comprising a display panel with a touch control unit, a glass cover plate being positioned at a light emitting side of the display panel, and a light guiding film for buttons being positioned on a side of the glass cover plate facing to the display panel, and further comprising a first flexible circuit board extended to be interposed between the light guiding film for buttons and the display panel, provided with a functional module electrically connected with the light guiding film for buttons and a functional module electrically connected with the touch control unit. A functional module for providing signals to the light guiding film for buttons and a functional module for providing signals to the touch control unit are integrated into one flexible circuit board, so that a thickness of one layer of flexible circuit board is reduced in the thickness direction of the display device.
