Title
(EN) Display panel, driving method thereof and display device
(ZH) 显示面板、其驱动方法及显示装置
Abstract
(EN) The invention discloses a display panel, a driving method thereof and a display device. The display panel comprises a plurality of pixel circuits arranged in a matrix mode, a plurality of data lines,a plurality of write-in control lines, a plurality of compensation control lines, a first driving circuit connected with the compensation control lines and a second driving circuit connected with thewrite-in control lines; each column of pixel circuits is corresponding to one data line, and each row of pixel circuits is corresponding to one write-in control line and one compensation control line;the first driving circuit outputs compensation control signals to each row of pixel circuits in sequence through a plurality of compensation control lines, and the second driving circuit outputs writing control signals to each row of pixel circuits in sequence through a plurality of writing control lines; the pulse width of the compensation control signal is equal to N times of the pulse width ofthe write-in control signal, the write-in control signals on two adjacent write-in control lines are not overlapped, and the overlapping time of the compensation control signals on two adjacent compensation control lines is equal to (N-1)/N of the pulse width of the compensation control signal.
(ZH) 本申请公开了一种显示面板、其驱动方法及显示装置,其中显示面板包括:矩阵排列的多个像素电路,多条数据线、多条写入控制线、多条补偿控制线、与多条补偿控制线连接的第一驱动电路、与多条写入控制线连接的第二驱动电路;每一列像素电路对应一条数据线,每一行像素电路对应一条写入控制线和一条补偿控制线;第一驱动电路通过多条补偿控制线依次向各行像素电路输出补偿控制信号,第二驱动电路通过多条写入控制线依次向各行像素电路输出写入控制信号;补偿控制信号的脉宽等于写入控制信号的脉宽的N倍,相邻两条写入控制线上的写入控制信号不交叠,相邻两条补偿控制线上的补偿控制信号的交叠时间等于补偿控制信号脉宽的(N‑1)/N。
