Abstract: A gate line driver (34) sequentially applies the gate voltage to a number of gate lines G1 - Gm by predetermined duration. Data lines are grouped into four groups each consisting of n lines (d1A - dnA: group A, d1B - dnB: group B, d1C - dnC: group C, and d1D - dnD: group D). A data line driver (40) and a multiplexer (38) sequentially perform for the data line groups A - D in the above predetermined duration application of data voltage to each data line in a predetermined data line group. A precharge controller (44) and a voltage switching circuit (46) apply to each of the data line groups A - D, through a transistor (42), a precharge voltage (+V1 or -V1) with the same polarity with that of data voltage being applied next time during the time from previous application of the data voltage to next application of it.

Abstract: To make it possible to execute the same application regardless of the number of connected panels even in a multi-panel environment. A host system (10), which transfers an image signal to a plurality of panels connected thereto, comprises: a panel ID recognition section (22) for recognising a panel ID of a single panel (30) or a predetermined number of collected panels (30) as a unit; a window ID allocation section (25) for allocating a window ID to a window which is a transfer processing unit of the image signal; a control signal output section (24) for outputting a control signal used for setting a window ID to be processed to the panel ID to be read out in transferring the image signal; and an image signal transfer section (26) for adding the window ID allocated by the window ID allocation section (25) to the image signal, thus transferring the image signal.
