Inspection circuit and display device thereof
Abstract:
An inspection circuit is used for inspecting signal wires of a display area. The inspection circuit includes a shorting bar, plural first shorting switches, and plural second shorting switches. The plurality of the first and the second shorting switches are disposed at different sides of the display area for increasing space between each adjacent shorting switch so as to reduce coupling effect. In the inspection circuit, a first shorting switch is electrically connected between the shorting bar and first end of one signal wire, and a second shorting switch is electrically connected between the second end of that signal wire and second end of another signal wire.
