Display Device Capable Of Driving at Low Speed

摘要

A display device capable of driving at low speed includes a display panel, on which display lines each including a plurality of pixels are formed, a driver unit for driving the pixels, and a timing controller which controls an operation of the driver unit and includes a first control logic unit and a second control logic unit. When a mode conversion control signal of an on-level is input during a normal drive, in which a length of one frame is set to P, the first control logic unit 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, assigns a length P to each of n sub-frames included in the one frame for the low speed drive, and controls the operation of the driver unit in an interlaced low speed driving scheme.

1. A display device capable of driving at low speed, which changes a frame frequency in response to a mode conversion control signal, the display device comprising:
a display panel, on which display lines each including a plurality of pixels are formed; a driver unit configured to drive the plurality of pixels; and a timing controller configured to control an operation of the driver unit and display an image on the display panel, the timing controller including a first control logic unit and a second control logic unit, wherein responsive to the mode conversion control signal being of an on-level during a normal drive, in which a length of one frame is set to P, the first control logic unit 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, the first control logic unit assigns a length P to each of n sub-frames included in the one frame for the low speed drive, and the first control logic unit controls operation of the driver unit in an interlaced low speed driving scheme, and wherein responsive to the mode conversion control signal being of an off-level in a predetermined sub-frame of the one frame for the low speed drive during an interlaced low speed drive, the second control logic unit detects a next sub-fame of the predetermined sub-frame as a conversion standby sub-frame, the second control logic unit controls the operation of the driver unit, and the second control logic unit scans all of display lines, which are not scanned until the predetermined sub-frame within the one frame for the low speed drive, in the conversion standby sub-frame.
