DISPLAY PANEL AND TESTING METHOD THEREOF
First Claim
1. A display panel having a display region and a non-display region, the display panel comprising:
- a first substrate, a second substrate, and a display medium located between the first substrate and the second substrate;
a plurality of data lines and a plurality of scan lines, the scan lines and the data lines being located on the first substrate within the display region;
a plurality of pixel units located on the first substrate within the display region, each of the pixel units being electrically connected to one of the scan lines and one of the data lines;
at least one testing line located on the first substrate within the non-display region, the scan lines crossing over the at least one testing line and being electrically insulated from the at least one testing line; and
at least one testing pad located on the first substrate within the non-display region, the at least one testing pad being electrically connected to the at least one testing line.

Abstract
A display panel and a testing method of the display panel are provided. The display panel has a display region and a non-display region and includes a first substrate, a second substrate, and a display medium. The display panel further includes scan lines, data lines, pixel units, at least one testing line, and at least one testing pad. The scan lines and the data lines are located on the first substrate within the display region. The pixel units are located on the first substrate within the display region. Each pixel unit electrically connects one of the scan lines and one of the data lines. The testing line is located on the first substrate within the non-display region, crosses over the scan lines, and is insulated from the scan lines. The testing pad is located on the first substrate within the non-display region and electrically connected to the testing line.

7. A testing method of a display panel, comprising:
-
providing a display panel, the display panel comprising; a first substrate, a second substrate, and a display medium located between the first substrate and the second substrate; a plurality of data lines and a plurality of scan lines, the scan lines and the data lines being located on the first substrate within the display region; a plurality of pixel units located on the first substrate within the display region, each of the pixel units being electrically connected to one of the scan lines and one of the data lines; at least one testing line located on the first substrate within the non-display region, the scan lines crossing over the at least one testing line and being electrically insulated from the at least one testing line; and at least one testing pad located on the first substrate within the non-display region, the at least one testing pad being electrically connected to the at least one testing line, wherein one of the scan lines in the display panel has a line defect; performing a melting and connecting process on an area where the at least one testing line crosses over the one of the scan lines having the line defect, such that the at least one testing line is electrically connected to the one of the scan lines having the line defect; and inputting a testing signal to the one of the scan lines having the line defect and measuring an output signal received from the at least one testing pad. - View Dependent Claims (8, 9, 10, 11, 12)
