  • Patent number: 11935912
    Abstract: A display apparatus including a thin film transistor (TFT) substrate; a first LED sub-unit, a second LED sub-unit, and a third LED sub-unit; first, second, third, and fourth electrode pads disposed between the TFT substrate and the first LED sub-unit; and connectors connecting the first, second, and third LED sub-units to a respective one of the electrode pads, in which the first, second, and third sub-units are configured to be independently driven; light generated from the first LED sub-unit is emitted to the outside of the display apparatus by passing through the second and third LED sub-units; light generated from the second LED sub-unit is emitted to the outside of the display apparatus by passing through the third LED sub-unit; and at least one of the connectors includes a first portion electrically connecting a first surface of the first LED sub-unit to the second electrode pad.

  • Patent number: 11663695
    Abstract: A display device to change an image displayed in a display area when the display area is changed includes a memory, a location output unit and a screen display unit. The memory stores size information of a display area displayed on a screen and the image data of the displayed image. The location computing unit computes a start point of the changed display area when the display area is changed. The display unit decodes data corresponding to the size of the display area based on the computed new start point from the image data to display the decoded data in the display area. Since the start point is obtained with center point of the changed display area and its size information and then a display area to be displayed is determined based on the start point, a current search location is maintained even when the screen is swung.

  • Patent number: 7755647
    Abstract: Provided is a display device and method configured to change an image displayed in a display area flexibly when the display area is changed. The flexible display device depending on change of a display area comprises a memory, a location output unit and a screen display unit. The memory is configured to store size information of a display area displayed on a screen and the entire image data of the displayed image. The location computing unit is configured to compute a start point of the changed display area when the display area is changed. The display unit is configured to decode data corresponding to the size of the display area based on the computed new start point from the image data to display the decoded data in the display area. Since the start point is obtained with center point of the changed display area and its size information and then an display area to be displayed is determined based on the start point, a current search location is maintained as it is even when the screen is swung.
