| 20130077736 | Shift Register and Driving Circuit Using the Same - Disclosed are a shift register that shows excellent operation reliability with elements less than those of the conventional structure and a gate driving circuit using the shift register. The gate driving circuit comprises each of a plurality of shift registers sequentially connected and respectively supplying scan signals to a plurality of gate lines of a display device. | 03-28-2013 |
| 20130083885 | BIDIRECTIONAL SHIFT REGISTER - Disclosed herein is a bidirectional shift register which is capable of preventing multi-outputs from both end stages. The shift register includes a plurality of stages for outputting scan pulses forward or reversely based on a start pulse and a plurality of clock pulses with a phase difference. A last one of the stages includes a forward scan controller for making a set node active and a reset node inactive based on any one of the clock pulses and a scan pulse from an upstream stage, a reverse scan controller for making the set node active and the reset node inactive based on any one of the clock pulses and the start pulse, and an output unit for outputting any one of a corresponding scan pulse and a deactivation voltage based on a voltage at the set node, a voltage at the reset node and any one of the clock pulses. | 04-04-2013 |
| 20100272227 | ELECTRONIC DEVICE, BARREL SHIFTER UNIT AND METHOD OF BARREL SHIFTING - An electronic device is provided which comprises a barrel shifter unit (BS) for performing a rotation of an input. The barrel shifter unit comprises a first and second barrel shifter (BS | 10-28-2010 |
| 20110170656 | BIDRECTIONAL SHIFTER REGISTER AND METHOD OF DRIVING SAME - A bidirectional shift register includes first, second, third and four control signal bus lines for providing first, second, third and fourth control signals, Bi | 07-14-2011 |
| 20080253500 | Flip-flop and shift register - 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. | 10-16-2008 |
| 20080304614 | ELECTRONIC MULTIMODE DATA SHIFT DEVICE, IN PARTICULAR FOR CODING/DECODING WITH AN LDPC CODE - An electronic device includes N inputs to receive R input data, R being able to take values from 1 to N, and N outputs. A configurable shift circuit is coupled between the N inputs and N outputs and has a cascade of shift stages, each shift stage comprising at least N controllable multiplexers. Each multiplexer includes first and second elementary inputs respectively coupled to a first input and a second input taken from among the N inputs so as to, on command, not shift a data item present on the first elementary input and shift a data item present on the second elementary input by an elementary shift value dependent on a rank of the shift stage, a direction of the shift being identical for each multiplexer. Control circuitry controls the multiplexers to deliver the R input data on R outputs. | 12-11-2008 |
| 20090129535 | SWITCH SET OF BI-DIRECTIONAL SHIFT REGISTER MODULE - A switch set used in a bi-directional shift register circuit includes a plurality of switch devices. Each switch device is controlled by corresponding control signals to switch the direction of the input signal. One of the switch devices includes a first switch unit for transmitting a shift register signal from a previous shift register to a shift register according to a first control signal, a second switch unit for transmitting a shift register signal from a next shift register to the shift register according to a second control signal. The first and the second control signals have the same frequency as the clock signal of the shift register circuit. | 05-21-2009 |
