20110148853 | DISPLAY PANEL - Noise is reduced at a so-called Q-node and a so-called A-node of shift registers in a gate lines driving block of a scan driven display system so that the display system can be safely operated even at elevated temperatures. A variety of techniques may be used to reduce the noise. A first of the techniques applies charging pulses to the A-node at a rate faster than just once every 2H durations, where 1H is the duration of a single row drive. More specifically, a plurality of so-called inverter circuits, rather than just one are included in each shift register stage and the inverters are operated in synchronism with out of phase clock signals so as to thereby increase the rate at which the A-node is pulsed to a high voltage level. A second technique charges up the Q-node in multiple steps. A third technique pulls down the carry line at times when it does not need to go high. A fourth technique combines one or more of the first through third techniques. | 06-23-2011 |

20120326148 | THIN FILM TRANSISTOR ARRAY PANEL AND MANUFACTURING METHOD THEREOF - A thin film transistor array panel and a manufacturing method therefor. A shorting bar for connecting a thin film transistor with data lines is formed separate from the data lines, and then the data lines and the shorting bar are connected through a connecting member. As a result, all the data lines are floated during manufacture, so that variation in etching speed between data lines does not occur. Since variation in etching speed between the data lines can be prevented, performance deterioration of the transistor caused by a thickness difference in the lower layer of the data line can be prevented, as can resulting deterioration in display quality. Also, the influence of static electricity can be reduced or eliminated. Furthermore, since the data lines and the shorting bar are connected to each other, the generation of static electricity can be prevented or reduced, and quality testing is more readily performed. | 12-27-2012 |
