Title (EN) DETECTION METHOD AND DEVICE FOR DISPLAY PANEL
(FR) PROCÉDÉ ET DISPOSITIF DE DÉTECTION POUR PANNEAU D'AFFICHAGE
(ZH) 显示面板的检测方法和装置
Abstract:
(EN) A detection method and device for a display panel. The detection method comprises: collecting a first detection image of a display panel, and acquiring a gray-scale value of each pixel point in the first detection image (110); determining pixel points of which the gray-scale values exceed a preset gray-scale range in the first detection image as first pixel points, determining a first communication area formed by the first pixel points in the first detection image, and calculating an aspect ratio of the first communication area (120); and searching a pre-established database for a target parameter matched with the aspect ratio of the first communication area, and determining a target type corresponding to the target parameter as the type of the display panel (130).
(FR) L'invention concerne un procédé et un dispositif de détection pour un panneau d'affichage. Le procédé de détection consiste : à collecter une première image de détection d'un panneau d'affichage et à acquérir une valeur d'échelle de gris de chaque point de pixel dans la première image de détection (110) ; à déterminer des points de pixel dont les valeurs d'échelle de gris dépassent une plage d'échelle de gris prédéfinie dans la première image de détection en tant que premiers points de pixel, à déterminer une première zone de communication formée par les premiers points de pixel dans la première image de détection, et à calculer un rapport de forme de la première zone de communication (120) ; et à rechercher dans une base de données préétablie un paramètre cible correspondant au rapport de forme de la première zone de communication, et à déterminer un type cible correspondant au paramètre cible en tant que type du panneau d'affichage (130).
(ZH) 一种显示面板的检测方法和装置,该检测方法包括:采集显示面板的第一检测图像,并获取第一检测图像中每个像素点的灰阶值(110);将第一检测图像中灰阶值超出预设灰阶范围的像素点确定为第一像素点,以及确定第一检测图像中各第一像素点构成的第一连通区域,并计算第一连通区域的横纵比(120);以及在预先建立的数据库中查找与第一连通区域的横纵比匹配的目标参数,并将目标参数对应的目标类型确定为显示面板的类型(130)。
