The invention discloses a test control circuit, a test control method, a display substrate and a display device, and relates to the field of display technologies so as to prevent the static electricity from damaging electronic devices inside a display panel through a test lead, thereby ensuring normal display of the display device. The test control circuit comprises at least one test terminal andat least one test lead, wherein each test terminal is connected with the corresponding test lead; each test lead is provided with at least one switching device; when the test leads are in at a detection state, all switching devices on each test lead are turned on; and when the test leads are in a non-detection state, at least one switching device on each test lead is turned off. The display substrate comprises the test control circuit provided by the technical scheme. The test control circuit, the test control method, the display substrate and the display device provided by the invention are applied to the display technologies.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a test control circuit and method, a display substrate and a display device. Background technique [0002] In recent years, with the rapid development of display technology, the display and production level of the display panel has been greatly improved, which not only has a good display effect, but also can provide users with a better experience. [0003] In order to ensure the stability of the picture displayed by the display panel, test leads connected to the test terminals are generally made on the display substrate included in the display panel, so as to use the test leads to transmit the test signals provided by the test terminals to the display panel for testing. The display effect of the display panel. However, static electricity is easily generated during the manufacturing process of the display panel, and the static electricity enters the display panel th...
