Abstract
A backlight module, a display device, and a method of assembling a display device are disclosed. The backlight module includes a backplate, a middle frame, and a bonding adhesive. The middle frame is disposed on the backplate. A first adhesive holding slot is disposed between the backplate and the middle frame. At least one adhesive passage hole is defined in the middle frame. One end of the at least one adhesive passage hole is connected to the first adhesive holding slot, and another end of the at least one adhesive passage hole defines an opening at a top of the middle frame.
Claims16
A backlight module, comprising:
- a backplate;
- a middle frame, arranged on the backplate;
- and
- a bonding adhesive;
- wherein a first adhesive holding slot is disposed between the backplate and the middle frame, and at least one adhesive passage hole is defined in the middle frame;
- wherein one end of the at least one adhesive passage hole is connected to the first adhesive holding slot, and another end of the at least one adhesive passage hole defines an opening at a top of the middle frame;
- wherein the bonding adhesive is disposed in the first adhesive holding slot, the middle frame is placed on the backplate for pressing and bonding, and the bonding adhesive in the first adhesive holding slot in the backplate flows to the opening at the top of the middle frame through the at least one adhesive passage hole and continues to spread outward, so that the bonding adhesive fills the first adhesive holding slot and the at least one adhesive passage hole and further covers the opening at the top of the middle frame, and further protrudes from a top surface of the middle frame.
A display device, comprising a display panel and a backlight module, the backlight module comprising:
- a backplate;
- a middle frame, arranged on the backplate;
- and
- a bonding adhesive;
- wherein a first adhesive holding slot is disposed between the backplate and the middle frame, and at least one adhesive passage hole is defined in the middle frame;
- wherein one end of the at least one adhesive passage hole is connected to the first adhesive holding slot, and another end of the at least one adhesive passage hole defines an opening at a top of the middle frame;
- wherein the bonding adhesive is disposed in the first adhesive holding slot, the middle frame is placed on the backplate for pressing and bonding, and the bonding adhesive in the first adhesive holding slot in the backplate flows to the opening at the top of the middle frame through the at least one adhesive passage hole and continues to spread outward, so that the bonding adhesive fills the first adhesive holding slot and the adhesive passage hole and further covers the opening at the top of the middle frame, and further protrudes from a top surface of the middle frame;
- wherein the display panel is arranged on the top of the middle frame of the backlight module, and is bonded and fixed to the middle frame by the bonding adhesive.
A method of assembling a display device, comprising:
- injecting a sufficient amount of bonding adhesive into a position corresponding to a first adhesive holding slot defined in a backplate;
- placing a middle frame on the backplate, squeezing the bonding adhesive to bond the middle frame and the backplate together, wherein when placing the middle frame on the backplate for pressing and bonding, the bonding adhesive in the first adhesive holding slot in the backplate flows to an opening in a top of the middle frame through at least one adhesive passage hole defined in the middle frame and continues to spread outward, so that the bonding adhesive fills the first adhesive holding slot and the at least one adhesive passage hole and further covers the opening at the top of the middle frame, and further protrudes from a top surface of the middle frame;
- and
- placing a display panel on the top of the middle frame to be fixed to the middle frame by the bonding adhesive.
