System for display images

Abstract

A system for displaying images including a display panel is provided. The display panel has a display area and a peripheral area. The display panel includes a metal layer disposed on a first substrate. A patterned planarization layer is disposed on the metal layer, having at least one opening corresponding to the peripheral area, wherein a portion of the metal layer is exposed through the opening. A second substrate is disposed opposite to the first substrate. A seal is disposed at the peripheral area and between the first and the second substrates, wherein the seal covers the metal layer through the opening of the patterned planarization layer.

1 . A system for displaying images, including a display panel, having a display area and a peripheral area surrounding the display area, wherein the display panel comprises:
 a first substrate;   a metal layer disposed on the first substrate;   a patterned planarization layer disposed on the metal layer, having at least one opening corresponding to the peripheral area, wherein a portion of the metal layer is exposed through the opening;   a second substrate disposed opposite to the first substrate; and   a seal disposed between the first and the second substrates and at the peripheral area, wherein the seal covers the metal layer through the opening of the patterned planarization layer.   
     
     
         2 . The system as claimed in  claim 1 , wherein an area of the opening of the patterned planarization layer is 5% to 100% of an area of the seal. 
     
     
         3 . The system as claimed in  claim 1 , wherein an area of the opening of the patterned planarization layer is above 10% of an area of the seal. 
     
     
         4 . The system as claimed in  claim 1 , wherein the opening of the patterned planarization layer comprises a loop-shaped opening or a plurality of holes. 
     
     
         5 . The system as claimed in  claim 4 , wherein the plurality of holes are disposed at corners of the peripheral area of the display panel. 
     
     
         6 . The system as claimed in  claim 1 , further comprising a passivation layer disposed between the patterned planarization layer and the metal layer, wherein the passivation layer completely covers the metal layer. 
     
     
         7 . The system as claimed in  claim 6 , wherein the material of the passivation layer comprises silicon nitride or silicon oxide. 
     
     
         8 . The system as claimed in  claim 1 , further comprising a passivation layer disposed over the patterned planarization layer, wherein the passivation layer completely covers the portion of the metal layer exposed through the opening of the patterned planarization layer. 
     
     
         9 . The system as claimed in  claim 8 , wherein the material of the passivation layer comprises silicon nitride or silicon oxide. 
     
     
         10 . The system as claimed in  claim 1 , wherein the patterned planarization layer is only disposed at the display area inside the seal. 
     
     
         11 . The system as claimed in  claim 1 , further comprising an insulating layer disposed between the metal layer and the first substrate, wherein a portion of the insulating layer is exposed by the opening of the patterned planarization layer. 
     
     
         12 . The system as claimed in  claim 11 , wherein the seal directly contacts the metal layer and the insulating layer through the opening of the patterned planarization layer. 
     
     
         13 . The system as claimed in  claim 1 , wherein the material of the patterned planarization layer comprises an organic photoresist and the material of the insulating layer comprises silicon nitride or silicon oxide. 
     
     
         14 . The system as claimed in  claim 1 , further comprising a display, wherein the display comprises the display panel. 
     
     
         15 . The system as claimed in  claim 14 , further comprising an electronic device, wherein the electronic device comprises:
 the display; and   a control unit coupled to the display to provide an input to the display such that the display displays images.   
     
     
         16 . The system as claimed in  claim 15 , wherein the electronic device comprises a mobile phone, digital camera, personal data assistant (PDA), notebook computer, desktop computer, television, car display or portable DVD player.
