摘要： A liquid crystal display device of the present invention capable of enlarging and displaying to a high picture quality even when display data having a lower resolution than a liquid crystal panel is inputted is provided with storage element groups every drain line within latches of a liquid crystal driver. A portion of the storage element groups simultaneously captures display data. In doing so, the same liquid crystal apply voltage is outputted from drain lines corresponding to these storage element groups. Storage element groups corresponding to neighboring drain lines then simultaneously capture display data so as to enlarge an image in the horizontal direction. The rate of enlargement can be regulated by changing the number of storage element groups simultaneously capturing display data. A scanning driver then simultaneously selects a plurality of rows with a select voltage being applied to the simultaneously selected rows of pixel elements in the same period so as to enlarge the image in the vertical direction. Enlarged displaying is therefore possible by the liquid crystal driver regulating an output period of the liquid crystal apply voltage even when rows are selected one at a time.

摘要： A liquid crystal display system is provided with a driving circuit which corrects the display position in a vertical direction to obtain an excellent display area even when the total vertical line number is short. According to the driving circuit, by switching the output alternating signal GM input to a scan driver 701-1 in a scan driving circuit 104, a selection voltage Vgon is reflected to all the output terminals of the scan driver 701-1 to switch plural lines at the same time and perform a write-in operation. In a scan driver 701-2 and subsequent scan drivers in the scan driving circuit 104, an FLM signal is input to successively reflect the selection voltage Vgon to the output terminals thereof and successively select the line, thereby performing a write-in operation.
