  • Patent number: 8054438
    Abstract: A liquid crystal display (LCD) apparatus and a method of manufacturing the same include a seal line having two protrusions, one of the protrusions having a liquid crystal (LC) injection hole. Moreover, the LCD apparatus having the seal line constitutes a closed loop. The display apparatus and the manufacturing method thereof increase production yields because the number of apparatus substrates for the display apparatus obtained from a mother substrate is increased by minimizing a distance between two adjacent apparatus substrates on the mother substrate. The method of manufacturing an exemplary LCD apparatus includes a one drop filling method or a vacuum injection method.

  • Patent number: 8031301
    Abstract: A display substrate includes a pixel, first, second and third gate lines, and a source line. The pixel includes first, second and third unit pixels, each generating a different color. The first, second and third gate lines are electrically connected to respective ones of the first, second and third unit pixels. The source line is electrically connected to each of the first, second and third unit pixels. Each of the first, second and third unit pixels includes a common electrode and a respective pixel electrode. The common electrode is formed on a substrate. The pixel electrodes are disposed over the common electrode such that the pixel electrode face the common electrode. Each of the pixel electrodes has a plurality of openings therethrough. This arrangement results in a wider display viewing angle and a reduction in the required number of source driver chips.

  • Patent number: 7649578
    Abstract: An array substrate includes a gate line, a data line, a thin-film transistor (TFT), a pixel electrode, a first sensor line, a second sensor line and a sensor electrode part. The TFT is electrically connected to the gate and data lines. The pixel electrode is formed in a unit area defined by the gate and data lines. The pixel electrode is electrically connected to the TFT. The first sensor line is substantially parallel with the gate line. The second sensor line is substantially parallel with the data line. The sensor electrode part is formed in the unit area and electrically connected to the first and second sensor lines. The sensor electrode part is adjacent to the pixel electrode in a large axis direction of the unit area.

  • Publication number: 20080170195
    Abstract: A display panel includes an array substrate, an opposite substrate facing the array substrate, and a liquid crystal layer interposed between the array and opposite substrates. The array substrate includes a gate wiring, a data wiring, a pixel section, a sensor wiring section, a sensor electrode section and a sensor pad section. The gate wiring is formed in a first direction. The data wiring is formed in a second direction crossing the first direction. The pixel section is electrically connected to the gate and data wirings. The sensor wiring section is spaced apart from the gate and data wirings. The sensor electrode section is electrically connected to the sensor wiring section. The sensor pad section applies a test voltage to the sensor wiring section in order to inspect a display panel defect. Therefore, a short defect, which is generated between the array substrate and the opposite substrate, may be easily inspected.

  • Publication number: 20080068364
    Abstract: A thin film transistor panel includes an insulating substrate including a display area and a peripheral area. A plurality of pixels is defined by a plurality of data lines that cross a plurality of gate lines. A pixel electrode is formed in each of the pixels. A plurality of dummy pixels is defined by a dummy data line that crosses the plurality of gate lines. A dummy pixel electrode is formed in each of the dummy pixels, and a thin film transistor including a gate electrode, a source electrode, a drain electrode, and a semiconductor. The thin film transistor display panel reduces or prevents a difference in brightness between pixels caused by a difference of coupling capacitance between the data line adjacent to the peripheral area and the other data lines.
