Patents by Inventor Haeyoon KANG

Haeyoon KANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10964274
    Abstract: A display device and a method of driving the same. Characteristics of driving transistors disposed in subpixels of a display panel are sensed and compensated for, thereby improving the image quality of the organic light-emitting display device. Changes in a data voltage between a point in time at which a blank period starts and a period in which the sensing of the driving transistors starts are reduced or minimized, thereby reducing deviations in the sensing of the characteristics of the driving transistors.
    Type: Grant
    Filed: November 6, 2019
    Date of Patent: March 30, 2021

  • Patent number: 9747842
    Abstract: An organic light emitting display includes a display panel including sharing pixel groups each including at least one unit pixel, a gate driving circuit generating sensing signals for initializing the unit pixels, and a data driving circuit which generates an initialization voltage to be applied to the unit pixels and outputs the initialization voltage through a plurality of initialization voltage supply channels. When the sensing signals each having a pulse width of N horizontal periods (where N is a positive integer equal to or greater than 2) are shifted while overlapping each other by (N?1) horizontal period, N initialization voltage supply channels are assigned to a plurality of vertically adjacent sharing pixel groups. N sharing pixel groups, being driven to overlap each other in response to the sensing signals, among the vertically adjacent sharing pixel groups are connected to different initialization voltage supply channels.

  • Patent number: 9460656
    Abstract: The present invention provides an organic light emitting display device that includes a display panel in which an organic light emitting diode and a driving circuit are disposed in each pixel area of a first pixel and a second pixel which are certain pixels among a plurality of pixels, a floating pattern insulated from at least one of a first electrode of the organic light emitting diode of the first pixel and a first electrode of the organic light emitting diode of the second pixel is formed in the display panel, or a connection pattern for electrically connecting the first electrode of the organic light emitting diode of the first pixel with the first electrode of the organic light emitting diode of the second pixel is formed.
