Abstract
A display panel includes a glass substrate having a display area and a non-display area. The non-display area is defined on an outermost area of the glass substrate. A display chip is disposed on the non-display area and functions as a driving element of the display panel. A testing metal line is disposed on the non-display area and wound along the non-display area. The testing metal line starts with a first test point and ends with a second test point, and the first test point and the second point are not connected with each other to form an open circuit. The first test point and the second test point are configured to electrically connect to an external resistance test instrument to detect a resistance value of the test metal line.
Claims15
A display panel, comprising:
- a glass substrate comprising a display area and a non-display area, the display area configured to display images, and the non-display area defined on an outermost area of the glass substrate;
- a display chip disposed on the non-display area and functioning as a driving element of the display panel;
- and
- a testing metal line disposed on the non-display area and wound along the non-display area, the testing metal line starting with a first test point and ending with a second test point, wherein the first test point and the second point are not connected with each other to form an open circuit, and the first test point and the second test point are configured to electrically connect to an external resistance test instrument to detect a resistance value of the test metal line.
A method for detecting a display panel, comprising:
- defining a display area and a non-display area on a glass substrate, the display area configured to display images, and the non-display area defined on an outermost area of the glass substrate;
- providing a display chip on the non-display area;
- depositing a testing metal line on the non-display area, the testing metal line wound along the non-display area, wherein the testing metal line starts with a first test point and ends with a second test point, and the first test point and the second point are not connected with each other to form an open circuit;
- and
- connecting the first test point and the second point to an external resistance test instrument to detect a resistance value of the test metal line.
A display panel, comprising:
- a glass substrate, comprising a display area and a non-display area, the display area configured to display images, and the non-display area defined on an outermost area of the glass substrate;
- a display chip, disposed on the non-display area and functioning as a driving element of the display panel;
- and
- a testing metal line, disposed on the non-display area and wound along the non-display area, the testing metal line starting with a first test point and ending with a second test point, wherein the first test point and the second point are not connected with each other to form an open circuit, and the first test point and the second test point are configured to electrically connect to an external resistance test instrument to detect a resistance value of the test metal line,
- wherein the glass substrate comprises an upper color film substrate and a lower thin-film transistor (TFT) array substrate, the TFT array substrate comprises a base substrate, a functional layer is disposed on the base substrate, a lip portion is disposed between an edge portion of the color film substrate and an edge portion of the TFT array substrate, and an exposed groove is disposed on the functional layer corresponding to the lip portion and penetrates in a direction towards the color film substrate, and wherein the first test point and the second test point of the testing metal line are located beneath the groove.
