Publication number: 20140015871Abstract: A displaying method for field sequential color displays using two color fields to produce a full color image is disclosed. The displaying method includes: providing a target full color image, displaying a first color field and displaying a second color field. The target full color image is formed by a first color image optical stimulus, a second color image optical stimulus and a third color image optical stimulus. The first color field displays the first color image optical stimulus and a first part of the third color image optical stimulus, while the second color field displays the second color image optical stimulus and a second part of the third color image optical stimulus, which compensates the shortage of the third color image optical stimulus in the first color field. The target full color image is generated by displaying the first and second color fields in sequence, so as to decrease the displaying frequency of field sequential color displays.Type: ApplicationFiled: September 18, 2013Publication date: January 16, 2014Applicant: AU OPTRONICS CORP.Inventors: YU-KUO CHENG, YI-PAI HUANG, YI-RU CHENG, HAN-PING D.

Publication number: 20080279176Abstract: A protocol is proposed for a mobile station to transmit Dual Tone Multi-Frequency (DTMF) to another mobile station. When a user presses a key on a source mobile station, which is connected to a target mobile station, DTMF data are transmitted via a digital channel to a base station first. Instead of converting the received DTMF data to a corresponding analog voice to the target mobile station, the base station forwards the DTMF data to the target station via a digital channel. The target mobile station parses the DTMF data and activates certain operation in response to the key pressed by the user.Type: ApplicationFiled: May 8, 2007Publication date: November 13, 2008Inventor: Jing-Ru Cheng

Publication number: 20060123375Abstract: An integrated circuit for locating failure process layers. The circuit has a substrate with a scan chain disposed therein, having scan cells connected to form a series chain. Each connection is formed according to a layout constraint of a minimum dimension provided by design rules for an assigned routing layer. Since the connection in the assigned routing layer is constrained to a minimum, the scan chain is vulnerable to variations in processes relevant to the assigned routing layer. The scan chain makes it easier to locate processes causing low yield rate of the scan chain.Type: ApplicationFiled: January 30, 2006Publication date: June 8, 2006Inventors: An-Ru Cheng, Chang-Song Lin, Tzu-Chun Liu, Huan-Yung Tseng

Patent number: 6806142Abstract: A method for manufacturing a ROM device includes a semiconductor substrate having an array of field-effect transistors within a ROM region. A first dielectric layer covers the array and all transistors are initially in an “ON” state. A second dielectric layer covers at least one layer of metal interconnection formed over the first dielectric layer. The bit lines do not overlap the transistor-sources. A coding photoresist layer is formed on the second dielectric layer and is patterned to form a plurality of apertures defining exposure windows exposing underlying field-effect transistors to be coded permanently to an “OFF” state. A code etching back process is implemented using the photoresist layer as a mask to etch the first and second dielectric layers, the sources of the MOSFETs, and a portion of the substrate through the exposure windows to form a deep trench, disconnecting the coded MOSFETs from the source lines.Type: GrantFiled: July 7, 2003Date of Patent: October 19, 2004Assignee: Faraday Technology Corp.Inventors: An-Ru Cheng, Kwo-Jen Liu, Chih-Hung Chen
