Abstract

A liquid crystal display panel includes a first substrate, a second substrate, and a liquid crystal layer formed between the first substrate and the second substrate. A pixel area is formed on the first substrate, and a driver is formed on the substrate and electrically connected with the pixel area. A plurality of lines are electrically connected with the driver, and a plurality of pads are electrically connected with the plurality of lines. The plurality of pads are formed in a straight line and are not electrically connected with each other except for the electric connection with the plurality of lines.

Claims

exact text as granted — not AI-modified
1 . A display device comprising:
 a substrate;   a plurality of test pads, including a first group of test pads and a second group of test pads, formed on the substrate;   wherein test pads of the first group are arranged to provide a drain signal for testing said display device.   
     
     
         2 . The display device according to  claim 1 , wherein test pads of the second group are arranged to provide a gate signal for testing said display device. 
     
     
         3 . The display device according to  claim 1 , wherein said first group of test pads are arranged in a straight line. 
     
     
         4 . The display device according to  claim 2 , wherein said second group of test pads are arranged in a straight line. 
     
     
         5 . The display device according to  claim 2 , wherein the first group of test pads and the second group of test pads are arranged in a straight line. 
     
     
         6 . The display device according to  claim 1 , wherein the first group of test pads are arranged to be used with primary colors displayed by said display device. 
     
     
         7 . The display device according to  claim 1 , wherein the first group of test pads are arranged to be coupled to a drain driver of the display device and are located outside of a hidden area where the drain driver is located. 
     
     
         8 . The display device according to  claim 2 , wherein the second group of test pads are arranged to be coupled to a gate driver of the display device and are located outside of a hidden area wherein the gate driver is located. 
     
     
         9 . The display device according to  claim 7 , wherein the first group of test pads comprises six pads. 
     
     
         10 . The display device according to  claim 8 , wherein the second group of test pads comprises three pads. 
     
     
         11 . The display device according to  claim 7 , wherein the test pads of the first group of test pads are arranged in an interleaved manner.
