Publication number: 20110254962Abstract: The invention discloses a controlling apparatus for a signal outputting circuit in an electronic system. The controlling apparatus includes a detecting circuit, a switch, and a controlling circuit. The detecting circuit is used for detecting whether the electronic system has an abnormal condition. The switch is electrically connected between a signal receiving terminal and the signal outputting circuit. The controlling circuit is electrically connected between the detecting circuit and the switch. Once the detecting circuit detects that the electronic system has the abnormal condition, the controlling circuit sets the switch into a high-impedance state.Type: ApplicationFiled: June 24, 2011Publication date: October 20, 2011Applicant: RAYDIUM SEMICONDUCTOR CORPORATIONInventors: Chih Chuan Huang, Hui Wen Miao, Ko Yang Tso

Patent number: 8004512Abstract: A power-on screen pattern correcting apparatus is for correcting start output data of output terminals of a source driver such that a power-on screen pattern of a display is substantially uniform. The correcting apparatus comprises a flip-flop, a first logic unit and a second logic unit. The flip-flop controls a level of an inner signal to be substantially equal to a low signal level in response to a low level of a power start signal. The first logic unit enables a first signal in response to the low level of the inner signal or a low level of a high-impedance control signal. The second logic unit enables a second signal such that the output terminals are coupled to a charge sharing line and the power-on screen pattern is uniform in response to the low level of the inner signal or a low level of a charge-sharing control signal.Type: GrantFiled: January 24, 2008Date of Patent: August 23, 2011Assignee: Raydium Semiconductor CorporationInventors: Yong-Nien Rao, Ko-Yang Tso, Hui-Wen Miao, Chin-Chieh Chao

Publication number: 20100164929Abstract: The invention discloses a source driver. The source driver comprises a plurality of channels and a control module. Each of the plurality of channels comprises an output buffer, an output pad, a driving switch, and a charge sharing switch. The control module is used to control a gate signal of the driving switch or the charge sharing switch in each channel to be changed linearly. By doing so, a peak current generated by the source driver can be lowered to reduce the electromagnetic interference (EMI).Type: ApplicationFiled: October 14, 2009Publication date: July 1, 2010Applicant: RAYDIUM SEMICONDUCTOR CORPORATIONInventors: Yi Cheng Chen, Yann Hsiung Liang, Chin Chieh Chao, Hui Wen Miao, Ko Yang Tso

Patent number: 7664219Abstract: A flip-flop is provided. The flip-flop is used in a shift register in a source driver. The flip-flop is used to receive a first clock signal, an input signal and output an output signal. The output signal is fed back to the flip-flop. The flip-flop includes a flop core for receiving the input signal and output the output signal. When the input signal and the output signal are all disabled, the flop core is disabled to function. When the input signal or the output signal is enabled, the flop core is enabled to function to output the output signal.Type: GrantFiled: March 3, 2008Date of Patent: February 16, 2010Assignee: Raydium Semiconductor CorporationInventors: Ko-Yang Tso, Hui-Wen Miao, Chin-Chieh Chao

Patent number: 7656203Abstract: A receiving circuit is provided for receiving a data signal and a clock signal, which are RSDS signals, and outputting an output data signal to a data driver. The receiving circuit includes a data comparator, a data intermediate circuit, a clock comparator, a clock intermediate, and a flip-flop. The data comparator, driven with a data bias current, receives the data signal, and outputs a compared data signal. The clock comparator, driven with a clock bias current, receives the clock signal, and outputs a compared clock signal. The flip-flop receives the compared data signal via the data intermediate circuit and the compared clock signal via the clock intermediate circuit. The phase difference between the compared data signal and the compared clock signal is improved by adjusting the data and the clock bias currents.Type: GrantFiled: March 3, 2008Date of Patent: February 2, 2010Assignee: Raydium Semiconductor CorporationInventors: Chih-Yu Lee, Yong-Nien Rao, Ko-Yang Tso, Hui-Wen Miao, Chin-Chieh Chao

Publication number: 20080260090Abstract: A shift register is provided for use in a data driver. The shift register includes a shift registering unit. The shift registering unit selectively receives a clock signal. The shift registering unit includes a flip-flop; and a first selection circuit. The first selection circuit selectively sends the clock signal to the flip-flop according to a first selection signal, wherein before the flip-flop receives a data signal that is enabled, the first selection circuit sends the clock signal to the flip-flop according to the first selection signal so that the flip-flop correctly outputs the enabled data signal according to the clock signal.Type: ApplicationFiled: April 2, 2008Publication date: October 23, 2008Applicant: Raydium Semiconductor CorporationInventors: Ko-Yang Tso, Hui-Wen Miao, Chin-Chieh Chao
