摘要： The present invention can realize better display of a dynamic image, and in addition, can make storage capacity of a memory smaller. A data conversion circuit 112 compares display data 102 of an n-th frame from the outside and display data 116 of the (n−1)-th frame stored in the memory 104, to generate a driving data signal 117 to deliver to a driver. Each time when a memory control circuit 103 reads display data q0, q5, q10, q15 corresponding to 20 pixels out of the display data 116 of the (n−1)-th frame, the memory control circuit 103 compresses display data d0–d19 of 20 pixels out of the display data 102 of the n-th frame from the outside to generated d0, d5, d10, d15, and stores the generated data into the same area where the display data q0, q5, q10, q15 of the display data of the (n−1)-th frame have been stored.

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.
