Problems solved by technology

In this way, when the reliability test is performed on the display panel, the residual detection signal line 120 will be corroded.
Moreover, as water and oxygen continue to enter, the corrosion position will continue to extend. When the corrosion position extends to the connection between the detection signal line 120 and the drive signal line 110, it will affect the transmission of the electrical signal in the drive signal line 110, resulting in display Abnormal and other issues

Abstract

The invention discloses a display panel, a preparation method, a detection method and a display device. By arranging a detection transistor between a detection signal line and a corresponding driving signal line, and by setting a first switch transistor to control all the detection transistors during lighting detection stage conduction, so as to provide the lighting detection signal to the display area to light up the display panel. In the reliability detection stage, the signal loaded through the third control signal line controls all the detection transistors to be cut off, so as to isolate the detection signal line from the driving signal line through the detection transistor, so as to avoid the influence of the driving signal due to the extension of the corrosion position of the detection signal line The transmission of the signal in the line, so as to avoid abnormal display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a preparation method, a detection method and a display device. Background technique [0002] With the development of display panel production technology, it has entered the era of large-scale automated production. After the display panel is manufactured, the display panel may have defects, so the quality of the display panel needs to be inspected. In order to avoid cost increase, before the display panel is assembled with driver IC (Integrated Circuit, integrated circuit), PCB (Printed Circuit Board, printed circuit board), FPC (Flexible Printed Circuit, flexible circuit board), it will be tested for lighting. The structure of the display panel corresponding to the lighting test stage, such as figure 1 As shown, it may include a base substrate 100, a plurality of driving signal lines 110 for inputting driving signals to the display area AA, and driving termina...
