Display device

Abstract

A display device includes an optical fingerprint sensor; a display panel; a patterned film disposed below the display panel and having an opening portion that exposes the optical fingerprint sensor; a heat dissipating layer disposed below the patterned film, and that dissipates heat; and a cushion layer disposed between the patterned film and the heat dissipating layer, and that absorbs an impact. The optical fingerprint sensor is disposed below the cushion layer, and the heat dissipating layer has an opening portion that has a size larger than a size of the opening portion of the patterned film.

What is claimed is: 
     
         1 . A display device comprising:

         2 . The display device of  claim 1 , further comprising an embossing layer disposed between the patterned film and the cushion layer, and including an opening portion. 
     
     
         3 . The display device of  claim 2 , wherein the cushion layer has an opening portion that has a size substantially the same as a size of the opening portion of the embossing layer. 
     
     
         4 . The display device of  claim 3 , wherein the opening portion of heat dissipating layer, the opening portion of the embossing layer, and the opening portion of the cushion layer overlap one another. 
     
     
         5 . The display device of  claim 1 , wherein the opening portion of the heat dissipating layer is located above the optical fingerprint sensor. 
     
     
         6 . The display device of  claim 1 , wherein each of the holes has either a circular shape, a quadrate shape, a rectangular shape, a triangular shape, or a rhombic shape. 
     
     
         7 . A display device comprising:
 an optical fingerprint sensor;   a display panel;   a patterned film disposed below the display panel;   a heat dissipating layer disposed below the patterned film, and that dissipates heat; and   a cushion layer disposed between the patterned film and the heat dissipating layer, and that absorbs an impact,   wherein the patterned film and the heat dissipating layer comprise identical opening portions each having a plurality of holes, and   the optical fingerprint sensor is disposed below the heat dissipating layer.   
     
     
         8 . The display device of  claim 7 , wherein each of the holes hole has either a circular shape, a quadrate shape, a rectangular shape, a triangular shape, or a rhombic shape. 
     
     
         9 . The display device of  claim 7 , further comprising an embossing layer disposed between the patterned film and the cushion layer. 
     
     
         10 . The display device of  claim 9 , wherein the embossing layer comprises an opening portion, and the cushion layer comprises an opening portion that is substantially the same size as the opening portion of the embossing layer,
 wherein the opening portion of the embossing layer and the opening portion of the cushion layer form an air gap.   
     
     
         11 . The display device of  claim 10 , wherein the opening portion of the patterned film, the opening portion of the heat dissipating layer, and the air gap are located above the optical fingerprint sensor. 
     
     
         12 . A display device comprising:
 an optical fingerprint sensor;   a display panel;   a patterned film disposed below the display panel;   a heat dissipating layer disposed below the patterned film and that dissipates heat;   a cushion layer disposed between the patterned film and the heat dissipating layer, and that absorbs an impact; and   an embossing layer disposed between the patterned film and the cushion layer,   wherein the patterned film has an opening portion, and the cushion layer has an opening portion that is substantially same size as the opening portion of the patterned film,   wherein the optical fingerprint sensor is disposed at the opening portions of the patterned film and the cushion layer, and   the heat dissipating layer has an opening portion, wherein the optical fingerprint sensor is disposed at the opening portion of the heat dissipating layer.   
     
     
         13 . The display device of  claim 12 , wherein the embossing layer has an opening portion, wherein the optical fingerprint sensor is disposed at the opening portion of the embossing layer. 
     
     
         14 . The display device of  claim 12 , wherein a size of the opening portion of the heat dissipating layer is larger than a size of the opening portion of the embossing layer. 
     
     
         15 . The display device of  claim 12 , further comprising an adhesive layer disposed between the display panel and the optical fingerprint sensor. 
     
     
         16 . The display device of  claim 12 , wherein a size of the opening portion of the heat dissipating layer is larger than a size of the opening portion of the cushion layer.
