Abstract

The invention relates to a defect detecting and repairing device and a defect detecting and repairing method of an optical sensor array panel. The defect detecting and repairing device comprises a detection unit, a process display unit and a location repairing unit, wherein the detection unit is used for detecting an analog electric signal output by an optical sensor array panel which is arranged on the detection unit and converting the analog electric signal into a digital electric signal; the process display unit is used for receiving the digital electric signal outputted by the detection unit and converting the digital electric signal into an image to be displayed, and can judge whether the optical sensor array panel has a defect or not according to the displayed image; and the location repairing unit is used for repairing the defect after locating the defect of the optical sensor array panel. According to the defect detecting and repairing device, operations of detecting, locating and repairing the defect are finished in the same detection repair device, and the position of each pixel unit of the optical sensor array panel is determined without determining a coordinate system; furthermore a sensor pixel unit with the defect can be located after the defect is found, and the repairing effect can be determined when the defect is repaired; and therefore, the operation method is simple and convenient, is low in error rate and high in operating efficiency.

Description

technical field [0001] The invention relates to the field of optical sensors, in particular to a defect detection and repairing device and method for an optical sensor array panel. Background technique [0002] The flat-panel X-ray detector is a new type of X-ray imaging device. Because the flat-panel X-ray detector has high spatial resolution and dynamic range, and can provide fast digital image acquisition methods, the flat-panel X-ray detector has obtained a wide range of applications. [0003] The main part of the flat-panel X-ray detector is the imaging system, and the core of the imaging system is the X-ray sensor array panel. The X-ray sensor array panel is composed of a plurality of pixel units, each pixel unit includes an X-ray sensor, and the X-ray sensor is a kind of light sensor. Optical sensors accept external optical signals and convert the optical signals into electrical signals for output, mainly including photodiodes, phototransistors, photoresistors, phot...
