Title:
液晶アクティブマトリクスアレイデバイス
Document Type and Number:
Japanese Patent JP2006500628
Kind Code:
A
Abstract:
An active matrix array device has driver circuitry for providing address signals to the matrix elements and which includes digital to analogue converter circuitry. The driver circuitry is arranged alongside one edge of the array of matrix elements, and comprises a multiple voltage level generator circuit providing a plurality of analogue voltage levels for addressing the matrix elements, with the plurality of levels being provided on outputs distributed substantially along the length of the one edge. A group of switches is associated with, and located at, each output of the voltage level generator circuit and provides signals to an output bus arranged alongside the one edge and having the first number of lines. This architecture enables a reference voltage bus line to be removed by interleaving the voltage selection switches.
