Abstract

The invention discloses an active matrix organic light emitting diode (AMOLED) display panel and a recovery method thereof. The AMOLED display panel comprises a display region and a peripheral circuitregion, wherein a data line is arranged in the display region, the peripheral circuit region comprises a first region, a second region and a third region, one end of the data line extends to a firstregion, the other end of the data line extends to a second region, a recovery line is arranged in the peripheral circuit region and extends to the second region from the first region to the third region, the recovery line is in insulation intersection with the data line in the first region, the recovery line is in insulation intersection with the data line in the second region, and the recovery line is configured to recovery the data line when the data line is circuit-shorted in the display region. By the AMOLED display panel, the unfavorable data line with short circuit can be recovered, a pixel with abnormal display in a display image is reduced to be within an acceptable range, and the final product yield is improved.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an AMOLED display panel and a repair method thereof. Background technique [0002] Flat panel displays are widely used in various electronic products such as TVs, computers, tablet computers and smart phones, and play a pivotal role in the electronic information industry. As an emerging representative of flat panel display, AMOLED (Active Matrix Organic Light Emitting Diode, active matrix organic light emitting diode) display panel has the advantages of self-illumination, wide viewing angle, bright color, high contrast, wide operating temperature range and suitable for flexible display. To develop rapidly. [0003] The AMOLED display panel includes criss-crossing data lines and scanning lines, and also includes a pixel structure located at the crossing area of ​​the data lines and the scanning lines, and a plurality of pixel structures are arranged in a matrix array. A typical...
