발명의 명칭: (EN) Starting-up brightness control method of organic light emitting panel
(ZH) 一种有机发光面板的开机亮度控制方法
요약서: front page image
(EN) The invention discloses a starting-up brightness control method of an organic light emitting panel. The method comprises steps of acquiring a to-be-displayed brightness corresponding to each pixel in a starting-up process; comparing the to-be-displayed brightness of each pixel with a preset brightness threshold value; if the to-be-displayed brightness is larger than the brightness threshold value, adjusting to the to-be-displayed brightness to be smaller than or equal to the brightness threshold value; and using the adjusted to-be-displayed brightness to control the corresponding pixel to carry out display. In this way, the ghost rate of the panel caused by too big voltage offset during starting up can be reduced and too fast aging speed of a panel device caused by too heavy local current is reduced.
(ZH) 本发明公开了一种有机发光面板的开机亮度控制方法。其中,所述方法包括:获取每个像素在开机过程中所对应的待显示亮度;将每个像素的待显示亮度与预设的亮度阈值进行比较;若待显示亮度大于亮度阈值,则将待显示亮度调整成小于或等于亮度阈值;利用调整后的待显示亮度控制对应的像素进行显示。通过上述方式,本发明能够减少开机时电压偏移过大造成面板残影的几率,降低由于局部电流过大造成面板器件老化过快的速度。
