20090051644 | DISPLAY DEVICE AND RELATED POSITIONING METHOD - A display device detects a touched position by making use of a inducing element and a counter electrode. The voltage produced by the counter electrode is able to affect a conductivity of the channel of the inducing element corresponding to the touched position. The inducing element and a readout circuit are disposed on a substrate of the display device. The counter electrode and a shielding element are both corresponded to the inducing element. The channel of the inducing element corresponding to the touched position changes the conductivity due to the voltage produced by the corresponding counter electrode, and an inducing signal is then generated. The inducing signal is furnished to the readout circuit for signal processing, and a readout signal is generated for analyzing the touched position. | 02-26-2009 |
