[0019] Such as figure 1 As shown, the first embodiment of the method for repairing the sensing signal line of the present invention includes:

[0020] S11: judging whether the sensing signal line is damaged;

[0021] combine figure 2 and image 3 As shown, in an OLED display device, especially an AMOLED display device, the luminous brightness of each OLED is determined by the driving current generated by the driving circuit. When the AMOLED display device displays a frame of images, the threshold voltage of the driving transistor will drift, making The driving current for driving the OLED changes, resulting in a change in the luminance of the OLED, which affects the display uniformity of a single pixel in a frame of images. Therefore, in the OLED display device, it can be set as figure 2 As shown in the compensation circuit 201, in the sensing phase, the compensation circuit 201 turns on the corresponding thin film transistor T2 through the sensing signal line SENSE to o...

Abstract

The invention discloses a method and device for restoring a sensing signal line and a display device. The method comprises the steps of judging whether the sensing signal line is damaged or not; if the sensing signal line is damaged, positioning the sensing signal line to acquire the damage position of the sensing signal line and restoring the sensing signal line. According to the method, the damaged sensing line can be positioned so as to perform restoration, so that the restored sensing line is enabled to acquire normal OLED sensing data, thus normal operations of an OLED compensation circuit are maintained, and the display stability of an OLED panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method, device and display device for repairing sensing signal lines. Background technique [0002] In the existing organic light-emitting diode (OLED) panel, the external compensation circuit needs to use the sensing signal line to obtain the sensing data of the OLED before compensating the light emission of the OLED. However, when there is a problem with the sensing signal line, the compensation circuit fails due to the abnormality of the acquired OLED sensing data. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a method, device and display device for repairing the sensing signal line, which can solve the problem that the compensation circuit is prone to failure in the prior art. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a metho...
