    Abstract: A disclosed display device includes a display panel with a plurality of pixels and a plurality of signal lines respectively connected to the pixels, and a panel driving circuit to drive the signal lines. The display device further includes a timing controller to receive a first panel self-refresh (PSR) signal and an input image data from a host system, to sense whether the input image data has a preset video format based on the first PSR signal and, if the input image data is sensed to have the preset video format, to control the panel driving circuit to perform normal driving of the signal lines at a first frame frequency in a first group of frames and interlaced low-speed driving of the signal lines at a second frame frequency lower than the first frame frequency in a second group of frames to display the input image data.

    Abstract: A display device capable of driving at low speed is disclosed. Pixels connected to a first data line on odd-numbered display lines of a display panel are positioned on one side of the left and right sides of the first data line, and pixels connected to the first data line on even-numbered display lines of the display panel are positioned on the other side of the first data line based on a Z-inversion scheme. When a mode conversion control signal for switching to an interlaced low speed driving mode is input during a normal drive, in which a length of one frame is set to P, a timing controller expands a length of one frame for a low speed drive to (n×P), where n is a positive integer equal to or greater than 2 and assigns a length P to each of n sub-frames of the one frame.

    Abstract translation: 公开了能够以低速行驶的显示装置。 连接到显示面板的奇数显示行上的第一数据线的像素位于第一数据线的左侧和右侧的一侧，并且连接到第一数据线上的偶数显示行上的像素 显示面板基于Z反转方案位于第一数据线的另一侧。 当在将一帧长度设置为P的正常驱动期间输入用于切换到隔行低速驱动模式的模式转换控制信号时，定时控制器将用于低速驱动的一帧的长度扩展为 n×P），其中n是等于或大于2的正整数，并且为一帧的n个子帧中的每一个分配长度P.
