A method of generating information to control display of images providing a display device with align pattern data to which box data having a maximum reference gray level is added, obtaining a first capture image generated based on the align pattern data to which the box data is added, providing the display device with one or more full pattern data respectively having one or more reference gray levels lower than the maximum reference gray level, and obtaining one or more second capture images generated based on the one or more full pattern data. The method also includes generating compensation data including compensation values at the one or more reference gray levels and the maximum reference gray level. The compensation data may be generated based on the one or more second capture images and a portion of the first capture image corresponding to the box data.

A tiled display device includes a plurality of display panels coupled to each other, where each of the plurality of display panels includes an edge region adjacent to a boundary line between the plurality of display panels, and a panel driver which multiplies input gray levels of input image data for the plurality of display panels by an adaptive gain, generates boundary compensated image data by adding boundary compensation gray levels to the input gray levels multiplied by the adaptive gain for the edge region, and drives the plurality of display panels based on the boundary compensated image data. The adaptive gain is gradually decreased over a plurality of frame periods in a case where a sum of each of the input gray levels for the edge region and a corresponding one of the boundary compensation gray levels exceeds a maximum gray level.

A semiconductor device includes first and second well regions having a first conductivity type, and a third well region between the first and second well regions having a second conductivity type different from the first conductivity type. A first active region is in the first well region. A second active region is in the second well region. A third active region is in the third well region. The third active region is closer to the second active region than to the first active region. A fourth active region is in the third well region. The fourth active region is closer to the first active region than to the second active region. A first conductive pattern is across the first and third active regions. A second conductive pattern is across the second and fourth active regions and parallel to the first conductive pattern.

In a driving method of a display apparatus using a driving circuit, when an image signal is a film image signal, first, second, and third original image signals are extracted based on the film image signal. Then, a first compensation image signal is generated based on first and second original image signals, and a second compensation image signal is generated based on second and third original image signals. The first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are sequentially output to have a driving frequency higher than an input frequency. In addition, the first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are output i, k, j, and k times, respectively. Thus, a trembling phenomenon perceived by a viewer of a film image may be prevented.
