In general, a display device that continuously outputs a specific image or character for a long time may cause a residual image due to accelerated deterioration of a specific pixel. In order to solve such a problem, an image can be displayed on the display panel. At this time, the image may move at regular intervals or at irregular intervals. In addition, the image can be moved with a constant direction such as clockwise or counterclockwise, or can move without having a constant directionality. When the image is moved and displayed, a part of the image disappears on the display panel, or an area where the image is not displayed on a part of the display panel, that is, a blank area may occur. For example, when the image is displayed by moving 5 pixels to the left, the left 5 pixels of the image disappear on the display panel, and the right 5 pixels of the display panel can become the blank area. In order to solve such a problem, the image correction method of FIG. 1 divides an image into an extended region and a reduced region on the basis of the movement amount of the image, calculates correction coordinates by expanding or reducing the coordinates of the image data implementing the image , The corrected image data can be generated by mapping correction coordinates to image data. Hereinafter, the image correction method of FIG. 1 will be described in detail.

1, when the first image is displayed on the display panel in order to prevent the afterimage, the X-axis movement amount and the Y-axis movement amount of the first image can be determined (S100) The X axis of the first image is defined (S120) by dividing the X axis extended region and the X axis reduced region based on the X axis movement amount and the X axis scaling ratio, and based on the Y axis movement amount and the Y axis scaling ratio The Y axis of the first image can be defined as a Y axis extended area and a Y axis reduced area (S130). The image correction method of FIG. 1 generates an X coordinate and a Y coordinate of the first image data for implementing the first image (S130), and determines whether the X coordinate is located in the X axis extended region or the X axis reduced region The X correction coordinate is calculated by expanding or reducing the X coordinate according to whether the Y coordinate is located in the Y axis extended area or the Y axis reduced area, and the Y correction coordinate is calculated by extending or reducing the Y coordinate (S150 )can do. 1, the first image data is mapped to the X correction coordinate and the Y correction coordinate, thereby generating second image data implementing the second image in which the first image is corrected (S160).

More specifically, when the first image is displayed on the display panel, the image correction method of FIG. 1 can determine the X-axis movement amount and the Y-axis movement amount of the first image (S100). In this case, the X-axis represents the horizontal axis of the display panel, and the Y-axis represents the vertical axis to the X-axis, that is, the vertical axis of the display panel. In one embodiment, the X-axis movement amount and the Y-axis movement amount of the first image may be set in advance and input to the flat panel display device. For example, the X-axis movement amount and the Y-axis movement amount of the first image can be determined based on the Vsync signal of the first image moving frame by frame. In another embodiment, the X-axis movement amount and the Y-axis movement amount of the first image can be input by the user. For example, the user can input the X-axis movement amount, the Y-axis movement amount, the movement period, and the movement direction of the first image. The X-axis movement amount and the Y-axis movement amount may include a movement direction. For example, if the X-axis movement amount is mx, the first image moves to the right when mx is larger than 0, and the first image can move to the left when mx is smaller than 0. If my is greater than 0, the first image moves upward. If my is less than 0, the first image can move downward.

The image correction method of FIG. 1 may define the X-axis of the first image by dividing the X-axis extended region and the X-axis reduced region based on the X-axis movement amount and the X-axis scaling ratio (S110). Specifically, the X-axis extended area can be determined by obtaining the area of the X-axis extended area by multiplying the X-axis moving amount and the X-axis scaling ratio and setting the position of the X-axis extended area based on the X-axis moving direction. The X axis reduction area can be determined as an area excluding the X axis extension area. The X-axis extended region can be enlarged to an area obtained by adding the X-axis movement amount of the first image to the X-axis extended region, and the X-axis reduced region can have an area .

The image correction method of FIG. 1 can define the Y axis of the first image by dividing the Y axis extended region and the Y axis reduced region based on the Y axis moving amount and the Y axis scaling ratio (S120). Specifically, the Y-axis extended area can be determined by obtaining the area of the Y-axis extended area by multiplying the Y-axis moving distance and the Y-axis scaling ratio and setting the position of the Y-axis extended area based on the Y-axis moving direction. The Y axis reduction area can be determined as an area excluding the Y axis extension area. The Y axis extended area can be enlarged to an area obtained by adding the Y axis movement amount of the first image to the Y axis extended area and the Y axis reduced area can be enlarged to an area obtained by subtracting the Y axis moving amount of the first image from the Y axis reduced area .

The image correction method of FIG. 1 may generate the X coordinate and the Y coordinate of the first image data for implementing the first image (S130). For example, when a first image is displayed on a display panel having a resolution of 300 * 700, 300 X coordinates and 700 Y coordinates can be generated for the first image data. The number of the X coordinate and the Y coordinate of the first image data is not limited thereto.

In the image correction method of FIG. 1, the X correction coordinate may be calculated (S140) by expanding or reducing the X coordinate according to where the X coordinate of the first image data is located in the X axis extended area or the X axis reduced area. Referring to FIG. 2, in the X correction coordinate calculation method, the position of the X coordinate is confirmed (S142), the X correction coordinate of the X axis extended area is calculated (S144), and the X correction coordinate of the X axis reduced area is calculated )can do. Specifically, the X correction coordinate calculation method of FIG. 2 can confirm the position of the X coordinate (S142). At this time, if the X coordinate is located in the X axis extended area, the X coordinate is expanded to calculate the X correction coordinate (S144). If the X coordinate is located in the X axis reduced area, the X coordinate is reduced to calculate the X correction coordinate (S146). The X correction coordinates can be calculated based on the X-axis movement amount and the X-axis scaling ratio. For example, by increasing the interval between the X-coordinates of the first image data located in the X-axis extended region, the X-coordinate of the first image data is expanded, and the X-coordinate of the first image data located in the X- By decreasing the interval, the X-coordinate of the first image data can be reduced.

In the image correction method of FIG. 1, the Y correction coordinate may be calculated (S150) by expanding or reducing the Y coordinate according to where the Y coordinate of the first image data is located in the Y axis extended area or the Y axis reduced area. 3, in the Y correction coordinate calculation method, the position of the Y coordinate is confirmed (S152), the Y correction coordinate of the Y axis extended area is calculated (S154), the Y correction coordinate of the Y axis reduced area is calculated (S156 )can do. More specifically, the Y correction coordinate calculation method of FIG. 3 can confirm the position of the Y coordinate (S152). At this time, if the Y coordinate is located in the Y axis extended area, the Y coordinate is expanded to calculate the Y correction coordinate (S154). If the Y coordinate is located in the Y axis reduced area, the Y coordinate is reduced to calculate the Y correction coordinate (S156). The Y correction coordinates can be calculated based on the Y-axis movement amount and the Y-axis scaling ratio. For example, by increasing the interval between the Y coordinates of the first image data located in the Y-axis extended region, the Y coordinate of the first image data is expanded, and the Y coordinate of the first image data located in the Y- By reducing the interval, the Y coordinate of the first image data can be reduced.

In the image correction method of FIG. 1, the first image data is mapped to the X correction coordinate and the Y correction coordinate, thereby generating second image data that implements the second image in which the first image is corrected (S160). Specifically, the first image data corresponding to the X coordinate and the Y coordinate of the first image data are mapped to the X correction coordinate and the Y correction coordinate, thereby generating second image data implementing the second image in which the first image is corrected can do. For example, when x1, which is the X coordinate of the first image data, is calculated as x2, which is the X correction coordinate, and y1, which is the Y coordinate of the first image data, is calculated as y2, which is the Y correction coordinate, (x1, y1) to the correction coordinates (x2, y2). In this manner, the correction coordinates corresponding to the coordinates of the first image data located in the extended area and the reduced area of the first image are calculated, and the first image data is mapped to the respective correction coordinates, And generate second image data for implementing the second image. Accordingly, when the first image moves according to the X-axis movement amount and the Y-axis movement amount, the second image with the first image corrected may be output.

As described above, the image correction method divides the first image displayed on the display panel into the extended area and the reduced area, generates the coordinates of the first image data implementing the first image, and outputs the coordinates of the first image data The second image data can be generated by mapping the first image data to the correction coordinates. The second image data may implement a second image in which a phenomenon that a part of the image disappears on the display panel or a blank area occurs on the display panel when the first image moves according to the X axis movement amount and the Y axis movement amount. Specifically, in the image correction method, the first image data located in the extended area of the first image is enlarged and displayed, thereby correcting the occurrence of the blank area on the display panel. Also, in the image correction method, the first image data located in the reduced area of the first image is displayed in a reduced size, so that the phenomenon that a part of the first image disappears on the display panel can be corrected. 1, when the first image is displayed on the display panel in order to prevent the afterimage, the second image data, which implements the second image in which the first image is corrected, It is possible to prevent the image from being lost on the panel.

FIGS. 4 to 7 are diagrams illustrating an example in which image correction is performed by the image correction method of FIG.

Referring to FIG. 4, a first image may be displayed on a display panel of a display device. The first image may be displayed and moved in order to prevent the afterimage from occurring on the display panel. The X-axis movement amount and the Y-axis movement amount of the first image are set in advance and input to the flat panel display device or can be input by the user. In this case, the X axis represents the horizontal axis of the display panel, and the Y axis represents the axis perpendicular to the X axis, that is, the vertical axis of the display panel. For example, the first image may be shifted three pixels in the left direction.

Referring to FIG. 5, the X-axis of the first image can be defined by dividing the X-axis extended region EA and the X-axis reduced region CA based on the X-axis movement amount and the X-axis scaling ratio of the first image. At this time, the X-axis scaling ratio may be a value set together with the X-axis movement amount. The area of the X-axis extended area EA can be determined by the product of the X-axis movement amount and the X-axis scaling ratio. For example, when the X-axis movement amount of the first image is mx and the X-axis scaling ratio is Sx, the area of the X-axis extended area EA can be determined by Equation (1).

[Equation 1]

의 면적을 갖는 영역으로 결정될 수 있다. X축 확장 영역(EA)은 X축 확장 영역(EA)에 제 1 영상의 X축 이동량을 더한 만큼의 면적으로 확장될 수 있다. X축 축소 영역(CA)은 X축 확장 영역(EA)을 제외한 영역일 수 있다. 즉, 제 1 영상의 우측

의 면적을 제외한 영역으로 결정될 수 있다. X축 축소 영역(CA)은 X축 축소 영역(CA)에서 제 1 영상의 X축 이동량을 뺀 만큼의 면적으로 축소될 수 있다. 구체적으로, 제 1 영상이 좌측 방향으로 3픽셀만큼 이동하고, X축 스케일링 비가 10일 때, X축 확장 영역(EA)의 면적은 [수학식 1]에 의해 3픽셀 * 10 = 30픽셀일 수 있다. X축 확장 영역(EA)은 제 1 영상의 X축 이동 방향의 반대 방향에 위치하므로, 제 1 영상의 우측 30픽셀이 X축 확장 영역(EA)으로 결정될 수 있고, 우측 30 픽셀을 제외한 영역이 축소 영역(CA)으로 결정될 수 있다. 예를 들어, 제 1 영상의 X축이 300픽셀이면, 좌측 270픽셀이 X축 축소 영역(CA)으로 결정될 수 있다. 제 1 영상의 확장 영역(EA)과 축소 영역(CA)을 구분하는 방법은 이에 한정되는 것은 아니다.The X-axis extended area EA may be positioned in the direction opposite to the X-axis moving direction of the first image. For example, if the X-axis movement amount mx of the first image is smaller than 0 (i.e., when the first image moves to the left), the X-axis extension region EA is displayed on the right side of the first image

As shown in FIG. The X-axis extended area EA can be extended to an area corresponding to the X-axis extended area EA plus the X-axis moving amount of the first image. The X-axis reduction area CA may be an area other than the X-axis extension area EA. That is, the right side of the first image

Can be determined as an area excluding the area of the area. The X axis reduction area CA can be reduced to an area obtained by subtracting the X axis movement amount of the first image from the X axis reduction area CA. Specifically, when the first image is shifted by 3 pixels in the left direction and the X-axis scaling ratio is 10, the area of the X-axis extended area EA can be 3 pixels * 10 = 30 pixels by Equation (1) have. Since the X axis extended area EA is located in the direction opposite to the X axis moving direction of the first image, the right 30 pixels of the first image can be determined as the X axis extended area EA, and the area excluding the right 30 pixels Can be determined as the reduced area CA. For example, if the X-axis of the first image is 300 pixels, the 270 pixels on the left side can be determined as the X-axis reduced area CA. The method of distinguishing the extended area EA and the reduced area CA of the first image is not limited to this.

Referring to FIG. 6, coordinates of the first image data can be generated. For example, when a first image is displayed on a display panel having a resolution of 300 * 700, 300 X coordinates and 700 Y coordinates can be generated for the first image data. That is, the first image data may include 300 coordinates on the X axis and 700 coordinates on the Y axis. Since the X-axis extended area EA of the first image defined in FIG. 5 is the right 30 pixels of the first image, it may correspond to the X-coordinates 270 to 300 of the first image data. Also, since the X-axis reduced area CA of the first image is 270 pixels on the left side of the first image, it can correspond to the X-coordinates 0 to 270 of the first image data.

When the X coordinate of the first image data is located in the X axis extended area EA, the X correction coordinate can be calculated by extending the X coordinate. For example, when the X-coordinate is located in the extended area, and the X-coordinate is represented by [Expression (2)), when the X-axis movement amount of the first image is mx, the X- 2].

&Quot; (2) "

In Equation (2), the X-axis length L of the first image data may be represented by the X-coordinate of the first image data. For example, when the X-axis movement amount of the first image is -3, the X-axis scaling ratio is 10, the X-axis length of the first image data is 300, and the X-coordinate of the first image is 295, Can be 294.5 by Equation (2). In this manner, the X correction coordinates corresponding to all the X coordinates of the first image data located in the X axis extended region of the first image can be calculated.

When the X coordinate of the first image data is located in the X axis reduced area CA, the X correction coordinate can be calculated by reducing the X coordinate. For example, when the X coordinate is located in the reduced area when the X axis movement amount of the first image is mx, the X axis scaling ratio is Sx, and the X axis length of the first image data is L, 3].

&Quot; (3) "

In Equation (3), the X-axis length L of the first image data can be represented by the X-coordinate of the first image data. For example, when the X-axis movement amount of the first image is -3, the X-axis scaling ratio is 10, the X-axis length of the first image data is 300, and the X-coordinate of the first image is 100, Can be 98.8 by Equation (3). In this manner, the X correction coordinates corresponding to all the X coordinates of the first image data located in the X axis reduced region of the first image can be calculated. The method of calculating the X correction coordinates is not limited to the formulas (2) and (3).

By mapping the first image data to the X correction coordinates, second image data can be generated. Specifically, the second image data can be generated by mapping the first image data corresponding to the X coordinate of the first image data to the X correction coordinate. For example, the first image data corresponding to the X coordinate 295 of the first image data may be mapped to the X correction coordinate 294.5.

Referring to FIG. 7, a second image in which the first image is corrected may be displayed on the display panel. The X-axis extended area EA of the first image can be extended to the X-axis extended area EA 'of the second image. That is, the first image data located in the X-axis extended area EA of the first image may be expanded and generated as the second image data located in the X-axis extended area EA 'of the second image. Also, the X-axis reduced area CA of the first image may be reduced to the X-axis reduced area CA 'of the second image. That is, the first image data located in the X-axis reduced area CA of the first image may be reduced to be the second image data located in the reduced area CA 'of the second image. For example, 1 image moves by 3 pixels in the left direction and the X-axis scaling ratio is 10, the first image data located at the right 30 pixels, which is the X-axis extended region (EA) of the first image, It can be displayed at 33 pixels. Therefore, as the first image moves 3 pixels to the left, blank areas occurring in the right three pixels of the display panel may not occur. Thus, when the first image is moved and displayed, the phenomenon that the blank area is generated in the display panel can be corrected by enlarging the X-axis extended area of the first image by an amount corresponding to the X-axis movement amount. Also, the first image data located at 270 pixels on the left side of the X-axis reduced region (CA) of the first image may be reduced and displayed at 267 pixels on the left side of the second image. Therefore, as the first image moves to the left by 3 pixels, the left three pixels of the first image may not disappear on the display panel. As described above, when the first image is moved and displayed, the phenomenon that the first image disappears in the display panel can be corrected by reducing the X-axis reduced area of the first image by an amount corresponding to the X-axis movement amount. As described above, in the image correction method, the first image is moved in the X-axis direction, but the moving direction of the first image is not limited thereto.

Fig. 6 is a block diagram showing a Y coordinate correction unit included in the Y coordinate correction unit; Fig.

8 to 10, the image correction apparatus 100 includes a movement amount determining unit 110, an X-axis region defining unit 120, a Y-axis region defining unit 130, a coordinate generating unit 140, A correction unit 150, a Y coordinate correction unit 160, a frame memory 170, and an image data generation unit 180.

When the first image is displayed on the display panel, the movement determining unit 110 can determine the X-axis movement amount and the Y-axis movement amount of the first image. In this case, the X-axis represents the horizontal axis of the display panel, and the Y-axis represents the vertical axis to the X-axis, that is, the vertical axis of the display panel. In one embodiment, the X-axis movement amount and the Y-axis movement amount of the first image may be set in advance and input to the flat panel display device. For example, the movement determining unit 110 may determine the X-axis movement amount and the Y-axis movement amount based on the Vsync signal of the first image moving in a frame unit. In another embodiment, the X-axis movement amount and the Y-axis movement amount of the first image can be input by the user. For example, the user can input the X-axis movement amount, the Y-axis movement amount, the movement period, and the movement direction of the first image.

The X-axis region defining unit 120 can define the X-axis of the first image by dividing the X-axis extended region and the X-axis reduced region based on the X-axis movement amount and the X-axis scaling ratio determined by the movement amount determining unit 110 . At this time, the X-axis scaling ratio may be a value set together with the movement amount. Specifically, the X-axis extended area can be determined by obtaining the area of the X-axis extended area by multiplying the X-axis moving amount and the X-axis scaling ratio and setting the position of the X-axis extended area based on the X-axis moving direction.

The Y-axis region defining unit 130 can define the Y-axis of the first image by dividing the Y-axis extending region and the Y-axis reducing region on the basis of the Y-axis movement amount and the Y-axis scaling ratio determined by the movement amount determining unit 110 . At this time, the Y-axis scaling ratio may be a value set together with the movement amount. Specifically, the Y-axis extended area can be determined by obtaining the area of the Y-axis extended area by multiplying the Y-axis moving distance and the Y-axis scaling ratio and setting the position of the Y-axis extended area based on the Y-axis moving direction. The Y axis reduction area can be determined as an area excluding the Y axis extension area. The coordinate generator 140 may generate an X coordinate and a Y coordinate of the first image data implementing the first image. For example, the coordinate generating unit 140 may generate the X coordinate and the Y coordinate of the first image data using Vsync, DE, clock signal, or the like.

The X coordinate correction unit 150 may calculate the X correction coordinate by expanding or contracting the X coordinate according to where the X coordinate of the first image data is located in the X axis extended area or the X axis reduced area. The X coordinate correction unit 150 may include an X coordinate detection unit 152, an X coordinate expansion unit 154, and an X coordinate reduction unit 156. The X coordinate detection unit 152 can detect the X coordinate position of the first image data. That is, the X coordinate of the first image data is set to the X coordinate extension section 154 (X coordinate extension section) according to whether the X coordinate of the first image data is located in the X axis extended region and the X axis reduced region defined in the X axis region defining section 120 ) Or to the X-coordinate reduction unit 156. When the X coordinate of the first image data is located in the X axis extended region, the X coordinate of the first image data can be transmitted to the X coordinate extension unit 154. The X-coordinate extension unit 154 may extend the X-coordinate of the first image data based on the X-axis movement amount and the X-axis scaling ratio. For example, by increasing the interval between the X coordinates of the first image data, the X coordinate of the first image data can be expanded. When the X coordinate of the first image data is located in the X axis reduced area, the X coordinate of the first image data can be transmitted to the X coordinate reducing unit 156. The X-coordinate reduction unit 156 can reduce the X-coordinate of the first image data based on the X-axis movement amount and the X-axis scaling ratio. For example, since the interval between the X coordinates of the first image data is reduced, the X coordinate of the first image data can be reduced. The X coordinate extended in the X axis extending unit 154 and the X coordinate reduced in the X axis reducing unit 156 become the X correction coordinates of the first image data and the X correction coordinates are transmitted to the image data generating unit 180 .

The Y coordinate correction unit 160 may calculate the Y correction coordinate by expanding or decreasing the Y coordinate depending on where the Y coordinate of the first image data is located in the Y axis extended area or the Y axis reduced area. The Y coordinate correction unit 160 may include a Y coordinate detection unit 162, a Y coordinate expansion unit 164, and a Y coordinate reduction unit 166. The Y coordinate detection unit 162 can detect the Y coordinate position of the first image data. In other words, the Y coordinate of the first image data is stored in the Y coordinate extension unit 164 according to whether the Y coordinate of the first image data is located in the Y axis extended region or the Y axis reduced region defined in the Y axis region defining unit 130, Or to the Y-coordinate decreasing unit 166. When the Y coordinate of the first image data is located in the Y axis extended area, the Y coordinate of the first image data can be transferred to the Y coordinate extension part 164. The Y coordinate extension unit 156 may extend the Y coordinate of the first image data based on the Y axis movement amount and the Y axis scaling ratio. For example, the interval between the Y coordinates of the first image data increases, so that the Y coordinate of the first image data can be extended. When the Y coordinate of the first image data is located in the Y axis contraction area, the Y coordinate of the first image data can be transmitted to the Y coordinate contraction unit 166. The Y-coordinate reduction unit 166 can reduce the Y-coordinate of the first image data based on the Y-axis movement amount and the Y-axis scaling ratio. For example, the Y coordinate of the first image data can be reduced by decreasing the interval between the Y coordinates of the first image data. The Y coordinate extended in the Y axis extending section 164 and the Y coordinate reduced in the Y axis reducing section 166 become the Y correction coordinates of the first image data and the Y correction coordinates are transmitted to the image data generating section 180 .

The frame memory 170 may store the first image data.

The image data generation unit 180 receives the X correction coordinates from the X coordinate correction unit 150 and receives the Y correction coordinates from the Y coordinate correction unit 160 and transmits the first image data from the frame memory 170 Can receive. The image data generation unit 180 may generate the second image data by mapping the first image data to the X correction coordinate and the Y correction coordinate. For example, when the X coordinate of the first image data generated by the coordinate generating unit 140 is x1, x1 is transmitted to the X coordinate correcting unit 150 and can be calculated as x2, which is an X correction coordinate, When the Y coordinate of the first image data generated by the image processing unit 140 is y1, y1 is transferred to the Y coordinate correction unit 160 and can be calculated as y correction coordinate y2. The image data generation unit 180 may map the first image data corresponding to the coordinates (x1, y1) of the first image data to the correction coordinates (x2, y2). In this manner, the coordinates of the first image data located in the extended region and the reduced region of the first image are calculated as correction coordinates, and the first image data is mapped to the respective correction coordinates, And generate second image data that implements the image.

As described above, the image correction apparatus 100 divides the first image displayed on the display panel into the extended region and the reduced region, generates the coordinates of the first image data implementing the first image, The second image data can be generated by calculating the correction coordinates in which the coordinates of the data are corrected and mapping the first image data to the correction coordinates. The second image data may implement a second image in which a phenomenon that a part of the image disappears on the display panel or a blank area occurs on the display panel when the first image moves according to the X axis movement amount and the Y axis movement amount. Specifically, the image correction apparatus 100 can enlarge and display the first image data located in the extended region of the first image, thereby correcting the occurrence of a blank region on the display panel. In addition, the image correction apparatus 100 can reduce the phenomenon that a portion of the first image disappears on the display panel by reducing the first image data located in the reduced area of the first image. 8, when the first image is displayed on the display panel in order to prevent the afterimage, the image correcting apparatus 100 generates second image data that implements the second image in which the first image is corrected It is possible to prevent the image from being lost on the display panel.
