Title:
IMAGE DISPLAY DEVICE, IMAGE DISPLAY DEVICE DRIVE METHOD, AND IMAGE DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/183264
Kind Code:
A1
Abstract:
An objective of the present invention is to cause light emission for location coordinate detection of a light pen in a short drive time while alleviating deterioration in contrast. To this end, an image display device drive method drives an image display unit by emitting a timing detection subfield, comprising: a write period which imparts a write pulse to a data electrode, imparts a scan pulse to a scan electrode, and causes a discharge cell to emit a write discharge; and a timing detection period which causes the discharge cell to emit a timing detection discharge which the write discharge has emitted. In the write period of the timing detection subfield, the scan pulse is imparted simultaneously to a plurality of the scan electrodes.
