  • Publication number: 20190189668
    Abstract: A semiconductor device includes a lower device and an upper device disposed on the lower device. The lower device includes a lower substrate, a lower plug pad disposed on the lower substrate, and a lower interlayer dielectric layer on the lower plug pad. The upper device includes an upper substrate, an etch-delay structure in a lower portion of the upper substrate, an upper plug pad disposed on a bottom surface of the upper substrate, an upper interlayer dielectric layer on the upper plug pad, and a via plug configured to penetrate the upper substrate and contact the upper plug pad and the lower plug pad. The via plug includes a first portion in contact with the upper plug pad and the first etch-delay structure, and a second portion in contact with the lower plug pad.

  • Patent number: 8941602
    Abstract: The present invention relates to a display device having a touch sensor in which the touch sensor is driven in a period which has a small noise component from the display device to reduce influence from the noise for minimizing a touch error; and a method for driving the same. The display device having a touch sensor includes a display panel, a panel driving unit for driving the display panel, a timing controller for controlling driving timing of the panel driving unit, a touch sensor integrated with the display panel attached thereto or built therein, and a touch controller for driving the touch sensor in a no noise period excluding a period in which the noise is generated periodically from the display panel by using at least one synchronizing signal from the timing controller, and calculating touch coordinates from a signal from the touch sensor and forwarding the touch coordinates.

  • Patent number: 8299985
    Abstract: Provided is an organic light-emitting display device. The organic light-emitting display device includes a light-emitting unit having a plurality of OLEDs to emit light, a light-emitting level setting unit setting a light-emitting level depending on a light-emitting area and/or change in a light-emitting degree of the light-emitting unit, a look-up table in which data for the light-emitting degree of the light-emitting unit that corresponds to each light-emitting area for each light-emitting level is set and stored, a light-emitting control unit controlling the light-emitting area of the light-emitting unit and/or the light-emitting degree depending on a light-emitting level with reference to the data set on the look-up table.

  • Publication number: 20060119545
    Abstract: A method and apparatus for driving a plasma display panel (PDP) with discharge cells arranged between a first substrate and second substrate, address electrodes arranged along a first direction, first electrodes and second electrodes arranged along a second direction crossing the first direction on opposite sides of each of a discharge cell, and scan electrodes arranged along the second direction that partition each discharge cell into two discharge spaces. The two discharge spaces of one discharge cell share a scan electrode. By selectively biasing the first electrodes and second electrodes during an address period, the two discharge spaces can be addressed during a first half and a second half of a single address period or during two distinct address periods. Sustain discharge for a single subfield can be generated in the two discharge spaces during a single sustain discharge period or during two distinct sustain discharge periods.

  • Publication number: 20060082521
    Abstract: In a display device, one field is divided into two groups of subfields. Light-emitting cells are selected by a selective write process in a first group of subfields and a gray scale is represented by a combination of weights of subfields. Light-emitting cells are selected by the selective write process in a first subfield of a second group of subfields, and non-light-emitting cells are selected from the light-emitting cells by a selective erase process in the remaining subfields of the second group of subfields. In the second group of subfields, a gray scale is represented by the sum of weights of subfields from when the light-emitting cell is selected in the first subfield to when the non-light-emitting cell is selected. In this manner, a gray scale of one field may be represented by a combination of the first and second groups of subfields.

  • Publication number: 20050264477
    Abstract: In a plasma display panel, one field is divided into a first group of subfields and a second group of subfields. A first subfield of the first group of subfields selects light-emitting cells using a selective write process, and the remaining subfields of the first group of subfields select non-light-emitting cells from the light-emitting cells using a selective erase process. In addition, a first subfield of the second group of subfields selects light-emitting cells using the selective write process, and the remaining subfields of the second group of subfields select non-light-emitting cells from the light-emitting cells using the selective erase process. In addition, a reset operation for initializing all discharge cells is performed in the first subfields of the first and second groups of subfields.
