Display panel

Abstract

A display panel includes a substrate and many driving chips. The substrate has many pad regions located in a non-display region of the substrate. Each pad region has many first pins with the same length disposed therein, and a pin pitch between two adjacent first pins, a width of each of the first pins, or both the pin pitch and the width vary with the positions where the first pins are disposed in the corresponding pad region. The driving chips are disposed in the non-display region of the substrate. Each driving chip has many second pins, and each second pin is electrically connected to each first pin correspondingly.

1 . A display panel, comprising:
 a substrate having a plurality of pad regions located in a non-display region of the substrate, wherein a plurality of first pins with the same length is disposed in each of the pad regions, and a pin pitch between the two adjacent first pins, a width of each of the first pins, or both said pin pitch and said width vary with the positions where the first pins are disposed in a corresponding pad region; and   a plurality of driving chips disposed in the non-display region of the substrate, wherein each of the driving chips has a plurality of second pins, and each second pin is electrically connected to each first pin.   
     
     
         2 . The display panel of  claim 1 , wherein each of the pad regions comprises a non expansion region and two expansion regions at two sides of the non expansion region. 
     
     
         3 . The display panel of  claim 2 , wherein each pin pitch between the two adjacent first pins in the non expansion region is the same. 
     
     
         4 . The display panel of  claim 3 , wherein the pin pitch between the two adjacent first pins in the expansion region is increased in a direction away from the adjoining non expansion region. 
     
     
         5 . The display panel of  claim 3 , wherein the width of each of the first pins in the expansion region is increased in the direction away from the adjoining non expansion region. 
     
     
         6 . The display panel of  claim 2 , wherein the width of each of the first pins in the non expansion region is the same. 
     
     
         7 . The display panel of  claim 6 , wherein the pin pitch between the two adjacent first pins in the expansion region is increased in the direction away from the adjoining non expansion region. 
     
     
         8 . The display panel of  claim 6 , wherein the width of each of the first pins in the expansion region is increased in the direction away from the adjoining non expansion region. 
     
     
         9 . The display panel of  claim 2 , wherein each pin pitch between the two adjacent first pins in the expansion region is the same. 
     
     
         10 . The display panel of  claim 9 , wherein the pin pitch between the two adjacent first pins in the non expansion region is increased in a direction away from the adjoining expansion region. 
     
     
         11 . The display panel of  claim 9 , wherein the width of each of the first pins in the non expansion region is increased in the direction away from the adjoining expansion region. 
     
     
         12 . The display panel of  claim 9 , wherein the width of each of the first pins in the expansion region is the same. 
     
     
         13 . The display panel of  claim 12 , wherein the pin pitch between the two adjacent first pins in the non expansion region is increased in the direction away from the adjoining expansion region. 
     
     
         14 . The display panel of  claim 12 , wherein the width of each of the first pins in the non expansion region is increased in the direction away from the adjoining expansion region.
