摘要： A data driver and a light emitting diode display device including the circuit that cause a pixel current through the light emitting diode to be independent of the threshold voltage of a transistor driving the light emitting diode. The data driver includes a voltage digital-analog converter for generating a data voltage and a current digital-analog converter for generating a sensing current, both corresponding to input data, and a voltage control block for receiving the pixel current that corresponds to the data voltage and is fed back from the pixel to the voltage control block changing the amount of current charging a capacitor in the voltage control block and controlling the data voltage supplied to the pixel. Controlling and adjusting the data voltage helps uniformity in the display brightness regardless of non-uniformity of transistors in each pixel.

摘要： A data driver and an organic light emitting display device including the data driver. The data driver including a shift register part to generate sampling signals in sequence, a latch part to store external data in response to the sampling signals, a current digital-analog converter to generate a data current corresponding to the data stored in the latch part, and a comparator producing a current corresponding to the difference between a pixel current and the data current. The comparator compares the pixel current fed back from each pixel with the data current, controls the data voltage by increasing or decreasing the current output, and supplies the controlled data voltage to the pixel. By controlling the data voltage an image is displayed with desired brightness regardless of non-uniformity of transistors in each pixel.

摘要： A pixel and an organic light emitting display using the pixel capable of displaying an image of uniform luminance. A pixel circuit is coupled with at least one scan line and at least one data line. The pixel circuit first charges a voltage corresponding to a first data signal across at least one capacitor when the first data signal is supplied from the data lines, and second charges the at least one capacitor when a current as a second data signal is provided. The pixel circuit controls an amount of current supplied to a second power supply from the first power supply through the organic light emitting diode according to the voltage charged in the at least one capacitor. Accordingly, an image of uniform luminescence may be displayed.

摘要： A data driver adapted to display an image with substantially uniform brightness is provided. The data driver includes a holding latch unit including holding latches for storing data, a signal generator including digital-analog converters for receiving the data to generate data signals, a first switching unit provided between the holding latch unit and the signal generator, and a second switching unit coupled to the signal generator to transmit the data signals to data lines. The first switching unit couples the holding latches to the digital-analog converters during a horizontal period in a manner different from the manner in which the holding latches and the digital-analog converters are coupled to each other during a previous horizontal period. Therefore, errors of the digital-analog converters are diffused so that it is possible to display an image with substantially uniform brightness.

摘要： An apparatus for use with an elevator car is operable to selectively lock an elevator car door. The apparatus verifies that the elevator car door is closed, locks the elevator car door, and verifies that a lock is engaged. Once conditions are met, the apparatus signals an elevator controller that the elevator car can move through a hoistway. The apparatus further ensures that passengers can safely disembark from the elevator car by detecting the position of the elevator car relative to a designated landing zone within the hoistway, and confirming the elevator car is stopped at a landing zone prior to disengaging the lock. The apparatus thus ensures that the elevator car door remains closed while the elevator car is in motion or between landing zones.

摘要： A stack for a fuel cell includes a first collecting plate having a first electric polarity, a second collecting plate having a second electric polarity different from the first electric polarity, and at least one electricity generator located between the collecting plates. The at least one electricity generator is for generating electric energy due to electrochemical reaction between hydrogen and oxygen to be collected by the collecting plates. Coupling members press the at least one electricity generator in an airtight connection between the collecting plates. A terminal member protrudes from the second collecting plate and is electrically connected to the first collecting plate and insulated from the second collecting plate, such that the terminal member is used as a first terminal having the first polarity. The second collecting plate or a second terminal member may also be used as a second terminal having the second polarity.
