technical field

The present invention relates to a display device, in particular to a display device suitable for a narrow frame.

Background technique

The current trend of display devices is to feature narrow bezels, which can not only reduce the overall size of the display device and achieve a larger display area, but also increase the beauty and modernity of the design. However, for the conventional display devices with narrow borders, there are still problems to be solved.

For edge-lit backlight modules, the narrow frame display device means that the display area of the panel will be closer to the edge of the light guide plate than the traditional display, so the light from the backlight source will leak from the shading area of the panel. Easy to happen, resulting in uneven brightness and darkness around the display area. In addition, for some narrow-frame display devices, the panel is directly carried by the backlight module. In such a structure, the panel is often placed directly on the optical film, which may easily cause high temperature curling (waving) of the optical film. ).
