(FR) PROCÉDÉ DE TEST DE PANNEAU
(ZH) 一种面板检测方法
Abstract
(EN)
The present invention provides a panel test method, comprising: S10, providing a host and at least two optical probes; S20, the host sending a lighting instruction and inputting a common electrode voltage to a panel group; S30, the optical probes measuring the flicker value of any one panel in the panel group and transmitting same back to the host; and S40, the host determining whether the flicker value is an optimal flicker value.
(FR)
La présente invention concerne un procédé de test de panneau comprenant : S10, l'utilisation d'un hôte et d'au moins deux sondes optiques ; S20, l'hôte envoie une instruction d'éclairage et applique une tension d'électrode commune à un groupe de panneaux ; S30, les sondes optiques mesurent la valeur de papillotement de l'un quelconque des panneaux dans le groupe de panneaux et transmettent celle-ci à l'hôte ; et S40, l'hôte détermine si la valeur de papillotement est une valeur de papillotement optimale.
