Title (EN) DISPLAY PANEL DETECTING METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE DÉTECTION DE PANNEAU D'AFFICHAGE
(ZH) 一种显示面板检测方法及装置
Abstract:
(EN) A display panel detecting method and device. The method comprises: acquiring a grayscale image corresponding to a display panel irradiated by a preset light source, the grayscale image comprising pixel electrode images corresponding to multiple pixel electrodes in the display panel (S101); acquiring a grayscale range corresponding to a pixel electrode image (S102); invoking a preset correspondence between preset grayscale ranges and pixel electrode types (S103); and identifying a pixel electrode type corresponding to the pixel electrode image according to the preset correspondence and the grayscale range (S104). According to the method, grayscales can be used to identify different types of pixel electrodes.
(FR) L’invention porte sur un procédé et un dispositif de détection de panneau d'affichage. Le procédé consiste : à acquérir une image en niveaux de gris correspondant à un panneau d'affichage exposé à une source de lumière prédéfinie, l'image en niveaux de gris comprenant des images d'électrode de pixel correspondant à de multiples électrodes de pixel dans le panneau d'affichage (S101) ; à acquérir une plage de niveaux de gris correspondant à une image d'électrode de pixel (S102) ; à invoquer une correspondance prédéfinie entre des plages de niveaux de gris prédéfinies et des types d'électrodes de pixel (S103) ; et à identifier un type d'électrode de pixel correspondant à l'image d'électrode de pixel en fonction de la correspondance prédéfinie et de la plage de niveaux de gris (S104). Selon le procédé, des échelles de gris peuvent être utilisées pour identifier différents types d'électrodes de pixel.
(ZH) 一种显示面板检测方法及装置,该方法包括:获取显示面板被预设光源照射时对应的灰阶图像,其中灰阶图像包括显示面板中的多个像素电极对应的像素电极图像(S101);获取像素电极图像对应的灰阶范围(S102);调用预设灰阶范围与像素电极类别的预设对应关系(S103);根据预设对应关系和灰阶范围识别像素电极图像对应的像素电极类别(S104)。该方法可以利用灰阶识别出不同类型的像素电极。
