METHOD OF DETECTING A SUBSTANDARD STATE, A DISPLAY MODULE AND AN ELECTRONIC DEVICE OPERATING THE SAME

摘要

A display module including a display area comprising a plurality of first conductive lines and a plurality of second conductive lines. The plurality of second conductive lines intersect the first conductive lines. A non-display area at least partially surrounding the display area. Test circuitry is electrically connected with the first conductive lines. A third conductive line is electrically connected between one of the first conductive lines and the test circuitry. The third conductive line includes a portion disposed in the non-display area and extending along a first periphery of the display area.
