摘要： A driving device for a display device includes a gray voltage generator generating a plurality of gray voltages, a voltage selector selecting an output voltage from the plurality of gray voltages, a voltage level converter converting a level of the output voltage selected by the voltage selector and applying the output voltage with a converted level to data lines, a first switching unit connecting the voltage level converter to the voltage selector and the data lines, and a second switching unit directly connecting the voltage selector and the data lines. Operating times of the first and second switching units are different. Accordingly, when a data voltage is charged in or discharged from a data line, since a separate discharging transistor or a separate discharging amplifier is not used, power consumption and an area of a data driver are reduced.

摘要： In a display apparatus and a manufacturing method of the display apparatus, the display apparatus includes a display panel having signal lines and an insulating layer, and a signal generator electrically connected to the signal lines and adhering to the display panel. The signal lines include pads formed at ends thereof, respectively. The organic insulating layer is partially removed such that the via holes are formed between the pads of the signal lines to reduce a step-difference between an area in which the pads are formed and an area in which the pads are not formed. Thus, the display apparatus may enhance the coupling force between the signal generator and the display panel.

摘要： A display substrate includes a plurality of pixel parts, each including a first and second gate lines, a source line, first, second, and third transistors, and a pumping capacitor. A display device includes a display panel, a gate driving part, a source driving part, and an output selecting part. Each pixel part of a display panel includes a transmissive part, a reflective part, and an adjusting part. The adjusting part adjusts the transmission voltage charged in the reflective part to a reflection voltage based on a control voltage. Thus, transmission voltage applied to the transmissive part is adjusted to reflection voltage to be applied to the reflective part. Therefore, optical reflectivity and optical transmissivity versus voltage are matched with each other, while embodying a single cell-gap and applying a single voltage.

摘要： A gate line extending in a horizontal direction is formed on an insulating substrate, and a data line is formed perpendicular to the gate line defining a pixel of a matrix array. Pixel electrodes receiving image signals through the data line are formed in a pixel, and a thin film transistor having a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode is formed on the portion where the gate lines and the data lines intersect. A storage wire including a storage electrode line in the horizontal direction, a storage electrode connected to the storage electrode line, and at least one of the storage electrode connection portions connecting storage electrodes of neighboring pixels is formed in the same direction as the gate line. A redundant repair line overlaps and is insulated from the storage wire at one end and overlaps the storage wire or the gate wire of a neighboring pixel at the other end is formed in the same layer as the data wire. Also, a storage wire connection portion connecting the storage wires of a neighboring pixel is formed in the same layer as the pixel electrode. In this structure, if portions of the gate wire or the data wire are disconnected, the portions overlapping the disconnected wire, the storage wire, and the redundant repair line are shorted to repair an open wire defect.
