  • Publication number: 20120190157
    Abstract: A mask includes: a substrate that includes a central area and a peripheral area disposed around the central area; and lenses disposed in rows and columns, in the central area and the peripheral area. The lenses of opposing sides of the peripheral area may be disposed in different rows or columns. For a given amount of input light, the lenses of the peripheral area may focus less light on a substrate than the lenses of the central area. The mask may be disposed over the substrate in different positions, and then the substrate may be irradiated through the mask, while the mask is in each of the positions. The peripheral portion of the mask may be disposed over the same area of the substrate, while the mask is in different ones of the positions.

  • Publication number: 20100271327
    Abstract: In a display panel, a display apparatus having the display panel, and a method of driving the display apparatus, a conductive spacer is interposed between an array substrate and an opposite substrate, and the conductive spacer electrically connects a pixel electrode and a common electrode when a touch event occurs for one or more embodiments. When a common voltage is applied to the pixel electrode by the touch event, an electric potential of a data line is lowered by the common voltage through a turned-on switching device. A signal reader periodically reads out the voltage of the data line and senses the touch event using the read-out voltage to detect a touch position at which the touch event occurs. Thus, the display panel having a touch screen function may be manufactured, and an aperture ratio in the display panel may be prevented from being deteriorated.

  • Patent number: 7655949
    Abstract: A thin film transistors (TFTs) substrate is structured to maintain as constant across the area of the substrate a kickback voltage due to Miller capacitance between the drain and gate of each TFT even in the presence of manufacturing induced misalignments between the drain electrodes and corresponding gate lines. Each thin film transistor includes a gate electrode, an active layer formed on the gate electrode so as to overlap the gate electrode, first and second source electrodes respectively connected to first and second data lines each of which crosses the gate line while being insulated from the gate line, and an elongated drain electrode located between the first and second source electrodes and disposed over the gate electrode so as to a crossing length of the drain electrode is larger than an underlying width of the gate electrode such that misalignment induced shifts of the position of the gate electrode relative to the drain electrode does not substantially change overlap area between the two.
