LCD device capable of changing the scan order and driving method thereof

摘要

An LCD device capable of changing the scan order and a driving method thereof are disclosed. The LCD device includes a plurality of pixel units which are arranged in an array of rows, first scan lines, second scan lines, and switch units. The pixel units of each row are divided into first pixel units and second pixel units. The switch units are respectively electrically coupled to one end of each first scan line and to one end of each second scan line for controlling conduction states of the first scan lines and the second scan lines, thereby controlling an order of updating the image signals for the first pixel units and the second pixel units. Thus, the scan lines are driven in the order according to whichever total sum of differences between gray values thereof is smaller, so that the power consumption of data chips is decreased.

主权项

1. A liquid-crystal display device capable of changing a scan order, comprising:
a plurality of pixel units which are arranged in an array of rows, the pixel units of each row being divided into a plurality of first pixel units and a plurality of second pixel units; a plurality of data lines, each of the data lines being electrically coupled to the first pixel unit and the second pixel unit of each row for transmitting image signals; a plurality of first scan lines and a plurality of second scan lines, the first scan lines and the second scan lines being disposed parallel to each other, wherein the pixel units of each row are disposed between one of the first scan lines and one of the second scan lines, the first pixel units and the second pixel units being respectively electrically coupled to the first scan line and the second scan line, characterized in that the liquid-crystal display device further comprises a plurality of switch units respectively electrically coupled to one end of each of the first scan lines and one end of each of the second scan lines for controlling conduction states of the first scan lines and the second scan lines, thereby controlling an order for updating the image signals for the first pixel units and the second pixel units, which further comprises a first switching signal line, which is electrically coupled to each of the first scan lines via the switch units for simultaneously connecting or disconnecting the first scan lines; and a second switching signal line, which is electrically coupled to each of the second scan lines via the switch units for simultaneously connecting or disconnecting the second scan lines.
