Abstract
(EN)
Disclosed in the present application are a method for quickly finding a common voltage of a display panel, and a test platform, comprising: measuring flicker values of a display panel (A); performing power exponent conversion on the flicker values, and performing quadratic function fitting on the converted flicker values and corresponding common voltages (B); and acquiring a common voltage value to serve as the common voltage (C).
(FR)
La présente invention concerne un procédé permettant de trouver rapidement une tension commune d'un panneau d'affichage, et une plateforme de test, consistant : à mesurer des valeurs de papillotement d'un panneau d'affichage (A) ; à réaliser une conversion d'exposant de puissance sur les valeurs de papillotement, et à réaliser un ajustement de fonction quadratique sur les valeurs de papillotement converties et les tensions communes correspondantes (B) ; et à acquérir une valeur de tension commune pour servir de tension commune (C).
(ZH)
本申请公开了一种快速寻找显示面板的公共电压的方法及测试机台。包括量测显示面板的闪烁值(A);对闪烁值进行幂次方转换,并对转换后的闪烁值与对应的公共电压进行一元二次函数拟合(B);获取公共电压值作为公共电压(C)。
