Abstract
(EN) The present invention provides an OLED plane and a drive method therefor, and a display apparatus. The OLED plane provided by the present invention comprises a plurality of pixel units arranged in multiple rows and multiple columns, each pixel unit comprising an OLED device. The OLED plane comprises multiple areas arranged along a column direction, each area comprising at least one row of pixel units and a cathode layer; OLED devices in each area share the cathode layer in the area, and the cathode layer in each area is separated from cathode layers in other areas. The OLED plane comprises a cathode voltage supply circuit which is configured to output a cathode voltage comprising an operating level to the cathode layers. The cathode voltage supply circuit is configured in a mode that the time for outputting the operating level to the cathode layer of at least one area is later than the time when all the pixel units in the area receive a scanning signal.
(FR) La présente invention concerne un plan OLED et un procédé de pilotage pour celui-ci, et un appareil d'affichage. Le plan OLED selon la présente invention comprend une pluralité d'unités de pixel agencées en de multiples rangées et de multiples colonnes, chaque unité de pixel comprenant un dispositif OLED. Le plan OLED comprend de multiples zones disposées le long d'une direction de colonne, chaque zone comprenant au moins une rangée d'unités de pixel et une couche de cathode; des dispositifs OLED dans chaque zone partagent la couche de cathode dans la zone, et la couche de cathode dans chaque zone est séparée des couches de cathode dans d'autres zones. Le plan OLED comprend un circuit d'alimentation en tension de cathode qui est configuré pour produire une tension de cathode comprenant un niveau de fonctionnement aux couches de cathode. Le circuit d'alimentation en tension de cathode est configuré dans un mode dans lequel l'instant d'alimentation au niveau de fonctionnement de la couche de cathode d'au moins une zone est postérieur à l'instant auquel toutes les unités de pixel dans la zone reçoivent un signal de balayage.
(ZH) 本公开提供一种OLED面板及其驱动方法、显示装置。本公开提供的OLED面板具有布置成多行和多列的多个像素单元,每个像素单元包括OLED器件。所述OLED面板包括沿列方向布置的多个区,每个区包括至少一行像素单元且具有阴极层,每个区中的各个OLED器件共用该区中的所述阴极层,每个区的所述阴极层与其它区的所述阴极层断开。所述OLED面板包括阴极电压供给电路,所述阴极电压供给电路被配置为向阴极层输出包括工作电平的阴极电压。所述阴极电压供给电路被配置为向至少一个区的阴极层开始输出所述工作电平的时间至少晚于该区中的全部像素单元接收到扫描信号的时间。
