Claim:
1. A testing device for testing a display panel, comprising: a test substrate configured to test data lines of the display panel; a plurality of connecting terminals arranged at one side of the test substrate configured to be connected to signal lines of the display panel, wherein a width of each of the connecting terminals is larger than a width of an input terminal of each of the signal lines, and the width of each of the connecting terminals is less than 300 μ; at least one test contact disposed on the test substrate; and at least one connecting line connected between the connecting terminals and the test contact; wherein the at least one test contact comprises a first test contact, a second test contact, a third test contact, a common voltage test contact, and the first test contact is configured to test red pixels of the display panel, and the second test contact is configured to test green pixels of the display panel, the third test contact is configured to test blue pixels of the display panel, and the common voltage test contact is configured to test common electrodes of the display panel; wherein, the testing device further comprises another test substrate configured to test gate lines of the display panel, and a connecting terminal on the another test substrate is an elongated terminal for contacting with input terminals of the gate lines, and a length of the connecting terminal on the another test substrate is longer than an arrangement length of the gate lines, a pitch between each adjacent two of the connecting terminals is identical Co a pitch between each adjacent two of the signal lines.
