Abstract
A liquid crystal display includes a glass substrate and a driver chip. The liquid crystal display further includes a testing line formed in the glass substrate and extending close to an edge of the glass substrate. The driver chip includes an input pin and an output pin, and two ends of the testing line are separately connected to the input pin and the output pin to form a closed loop. Whether the glass substrate has a crack is determined by measuring whether the testing line is in a closed circuit. The present invention further provides an electronic apparatus and a liquid crystal display testing method. In the present invention, whether a glass substrate has a crack is determined by detecting whether a testing line is in a closed circuit, so as to implement automatic detection without disassembling, thereby increasing detection efficiency.
