Abstract

A backlight structure includes a light guide plate, a light emitting unit, a reflection sheet, a fluid solidification layer and an adhesive layer. The light guide plate has a light incident surface, a light exit surface, a bottom surface and a side surface opposite to the light exit surface. Face shot. The reflective sheet is arranged under the bottom surface to reflect the light emitted from the bottom surface. The fluid solidification layer is disposed on the side surface to block the light from exiting through the side surface. The adhesive layer is bonded between the light guide plate and the reflective sheet, so as to limit the fluid solidification layer from entering the area between the reflective sheet and the light guide plate during the process of being arranged on the edge of the reflective sheet.

Description

technical field [0001] The invention relates to a backlight structure and a manufacturing method thereof, in particular to a backlight structure capable of preventing edge light leakage and a manufacturing method thereof. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Recently, with the improvement of consumers' visual demands, a luminous backlit keyboard has become a new development direction of the industry. Generally speaking, a backlit keyboard uses a side-lit backlight module as its light source, that is, the light-emitting diode used to emit light is arranged on one side of the light-incident surface of the light guide plate, so that the light emitted by the light-emitting diode Then, the light can enter the light guide plate from the light incident surface and exit from the light exit surface of the light guide plate, so ...
