Display device

Abstract

A display device includes a display panel, a vibrator and an adhesive layer. The vibrator is disposed on a surface of the display panel. The adhesive layer is disposed between the display panel and the vibrator, and a part of the adhesive layer contacts the display panel and another part of the adhesive layer contacts the vibrator.

 a display panel;   a vibrator, disposed on a surface of the display panel; and   an adhesive layer, disposed between the display panel and the vibrator, wherein a part of the adhesive layer contacts the display panel, and another part of the adhesive layer contacts the vibrator.   
     
     
         2 . The display device as claimed in  claim 1 , further comprising a flexible circuit board, wherein the flexible circuit board is disposed adjacent to the vibrator, or the flexible circuit board at least partially overlaps the vibrator. 
     
     
         3 . The display device as claimed in  claim 1 , wherein the vibrator has a first electrode plate, a piezoelectric material and a second electrode plate, and the piezoelectric material is disposed between the first electrode plate and the second electrode plate. 
     
     
         4 . The display device as claimed in  claim 3 , wherein the piezoelectric material comprises a piezoelectric ceramic material or a polyvinylidene fluoride film. 
     
     
         5 . The display device as claimed in  claim 1 , further comprising a frame which the adhesive layer at least partially contacts. 
     
     
         6 . The display device as claimed in  claim 5 , wherein the vibrator has a first thickness, the frame has a second thickness, and a ratio of the first thickness to the second thickness is between 50% to 70%. 
     
     
         7 . The display device as claimed in  claim 1 , wherein the display panel has a display region, the vibrator has a first area, the display region of the display panel has a second area, and a ratio of the first area to the second area is larger than or equal to 5% and smaller than or equal to 50%. 
     
     
         8 . The display device as claimed in  claim 1 , further comprising a plurality of pressure sensors disposed on the display panel. 
     
     
         9 . The display device as claimed in  claim 8 , wherein the pressure sensors are disposed at four corners of the display panel. 
     
     
         10 . The display device as claimed in  claim 1 , wherein the adhesive layer is a partial adhesive structure or a whole adhesive structure. 
     
     
         11 . The display device as claimed in  claim 1 , wherein the display panel has a display region, and the vibrator overlaps the display region. 
     
     
         12 . The display device as claimed in  claim 1 , wherein the display panel has an intermediary frame covering the vibrator and the one surface of the display panel. 
     
     
         13 . The display device as claimed in  claim 12 , wherein the display panel has an outer frame covering the intermediary frame. 
     
     
         14 . The display device as claimed in  claim 1 , wherein the vibrator has a lower vibrating frequency larger than or equal to 1 Hz and smaller than or equal to 250 Hz, when being used to provide a touch feedback function. 
     
     
         15 . The display device as claimed in  claim 1 , wherein the vibrator has a higher vibrating frequency larger than or equal to 20 Hz and smaller than or equal to 20 KHz, when being used to generate a sound. 
     
     
         16 . The display device as claimed in  claim 1 , further comprising a support substrate disposed between the vibrator and the adhesive layer. 
     
     
         17 . An electronic device, comprising:
 a display panel;   a vibrator, disposed on a surface of the display panel; and   an adhesive layer, disposed between the display panel and the vibrator, wherein a part of the adhesive layer contacts the display panel, and another part of the adhesive layer contacts the vibrator.   
     
     
         18 . The electronic device as claimed in  claim 17 , further comprising a flexible circuit board, wherein the flexible circuit board is disposed adjacent to the vibrator, or the flexible circuit board at least partially overlaps the vibrator. 
     
     
         19 . The electronic device as claimed in  claim 17 , further comprising a plurality of pressure sensors, wherein the pressure sensors are disposed at four corners of the display panel. 
     
     
         20 . The electronic device as claimed in  claim 17 , wherein the vibrator has a lower vibrating frequency larger than or equal to 1 Hz and smaller than or equal to 250 Hz, when being used to provide a touch feedback function.
