Title:
タッチ感知式装置及び方法
Document Type and Number:
Japanese Patent JP2005538443
Kind Code:
A
Abstract:
A touch sensitive matrix display senses touch input in sense periods (SP) which are selected to occur non-concurrently with data (DA) written to the pixels ( 10 ) of the matrix display during the addressing period (AP). As now, no data (DA) is written to the display while the sensing is performed during the sense periods (SP), the sensing will be less complicated. The sense periods (SP) are selected to occur in-between successive addressing periods (AP) because the display has pixels ( 10 ) of which the optical state is maintained substantially longer than the addressing period (AP) lasts. Such a hold period (HP) which lasts substantially longer than the addressing period (AP) is for example available in bistable displays such as electrophoretic displays.
