Abstract

The present invention provides testing device and method of flat-panel display panel. The method includes: a step for marking the flat irradiation virtual light source identical to the calibration mark, wherein the calibration mark is formed on the flat-panel display panel placed on the workstation; a step for picking up the calibration mark and the light source mark; a step for calculating the relative coordinate value between the calibration mark and the light source marker, driving the workstation based on the relative coordinate value, to align the calibration mark and the light source marker; and a step for aligning the calibration mark and the light source marker, and then setting the standard position of the workstation.

Description

technical field [0001] The invention relates to an inspection device and method for a flat panel display panel. Background technique [0002] With the realization of the mass production technology and research and development results of liquid crystal display devices (TFT-LCD), the main product of flat panel displays, large-scale and high-resolution products have been developed rapidly. In addition to notebooks and computer products, large-scale products have also been developed. Display and other application products have the potential to gradually replace the existing CRT, and the proportion of such products in the display industry is gradually increasing. In today's information society, the importance of display as a visual information transmission medium is becoming more and more prominent, especially under the trend of light, thin, short and small development of all electronic The requirements for image quality and portability are getting higher and higher. [0003] L...
