Abstract

The invention provides a display panel and a manufacturing method thereof, and a TFT test method in order to comprehensively evaluate the display effect of electroluminescent layers and the electrical characteristics (such as short-range uniformity) of thin-film transistors in a display panel. The display panel comprises a display area and a peripheral area of the display area. The peripheral area comprises an electroluminescent layer test area, a TFT test area, and outgoing lines. The electroluminescent layer test area includes multiple thin-film transistors respectively provided with an electroluminescent layer, a first test line connected with the sources of the multiple thin-film transistors respectively provided with an electroluminescent layer, and a switch lead and a second test line which are connected with the gates of the multiple thin-film transistors respectively provided with an electroluminescent layer. The TFT test area includes multiple thin-film transistors. Each of the multiple outgoing lines is used to connect the source and drain metal layer of one thin-film transistor in the electroluminescent layer test area and the source and drain metal layer of one thin-film transistor in the TFT test area.

Description

Technical field [0001] The invention relates to the field of liquid crystal panel display, in particular to a display panel, a manufacturing method thereof, and a TFT testing method. Background technique [0002] With the gradual improvement of people’s living standards, people’s requirements for display quality are getting higher and higher. In the prior art, the technology of liquid crystal displays (LCD) has been very mature, and the application of liquid crystal displays is also very extensive, such as mobile phones, cameras, Computers, TVs and other display screens are all liquid crystal displays. With the massive demand for products, the development of display technology has been objectively promoted, and new display technologies have emerged, such as low-temperature polysilicon (LTPS) and organic diode (OLED) display technologies. Among them, the active matrix organic light-emitting diode panel (AMOLED) is the key development target of the next-generation display technolo...
