Title
(EN) OLED (Organic Light Emitting Diode) panel, drive method of OLED panel, and display device
(ZH) OLED面板及其驱动方法、显示装置
Abstract
(EN) The invention provides an OLED (Organic Light Emitting Diode) panel, a drive method of the OLED panel and a display device, and belongs to the technical field of display. The OLED panel comprises a plurality of rows of grid lines, a plurality of columns of data lines and a pixel unit, the grid lines and the data lines are arranged in a crossing way, the pixel unit is defined at the crossing position of the grid line and the data line; the pixel unit internally comprises OLED devices; the OLED panel is divided into a plurality of zones in the column direction, cathodes of various OLED devices in each zone share one cathode layer, the cathode layers in various zones are arranged in a disconnecting way; and the OLED panel further comprises a grid driver, a cathode voltage supply unit and a time sequence control unit, wherein the time sequence control unit is used for controlling the cathode voltage supply unit to write the starting time of the operating level into each cathode layer, andthe starting time of the operating level is at least later than the end time of the grid driver writing a scanning signal to the last row of grid line in the corresponding zone.
(ZH) 本发明提供一种OLED面板及其驱动方法、显示装置,属于显示技术领域。本发明的OLED面板,包括:交叉设置的多行栅线和多列数据线,以及在所述栅线和所述数据线交叉位置出限定出的像素单元;所述像素单元中包括OLED器件;所述OLED面板沿列方向划分为多个区,每个区中的各个所述OLED器件的阴极共用一个阴极层,且各个区中的所述阴极层断开设置;所述OLED面板还包括栅极驱动器、阴极电压供给单元、时序控制单元;其中,所述时序控制单元,用于控制所述阴极电压供给单元给每个所述阴极层写入工作电平的起始时间至少晚于,所述栅极驱动器给该阴极层所对应区中的最后一行栅线写入扫描信号的终止时间。
