1. A display panel comprising:
a plurality of rows of pixels, each row of pixels including a plurality of pixels; a first gate driving circuit including a plurality of first gate driving units, each first gate driving unit outputting a first scan signal for driving a row of pixels coupled to the first gate driving unit; a second gate driving circuit including a plurality of second gate driving units, each second gate driving unit outputting a second scan signal for driving a row of pixels coupled to the second gate driving unit; a source driving circuit coupled to the plurality of pixels for transmitting data signals to the plurality of pixels; a first inspection circuit including a plurality of first transistors, each first transistor including:
a first terminal coupled to a first test pad;a control terminal coupled to a corresponding first gate driving unit; anda second terminal coupled to the control terminal of the first transistor; and a second inspection circuit, including a plurality of second transistors, each second transistor including:
a first terminal coupled to a second test pad;a control terminal coupled to a corresponding second gate driving unit; anda second terminal coupled to the control terminal of the second transistor; wherein when the first gate driving unit outputs the first scan signal, the first scan signal enables the first transistor so as to transmit the first scan signal to the first test pad while the first transistor is enabled, and when the second gate driving unit outputs the second scan signal, the second scan signal enables the second transistor so as to transmit the second scan signal to the second test pad while the second transistor is enabled for determining whether the first gate driving unit and the second gate driving unit are able to output the first scan signal and the second scan signal correctly.
