2, a display device of a display panel including a plurality of pixels each composed of RGB sub-pixels will be briefly described, and then a display panel including a plurality of pixels each composed of RWGB sub- Will be briefly described.

FIG. 2 shows a display device according to an embodiment including a display panel including a plurality of pixels composed of four sub-pixels. FIG. 3 shows a display device according to another embodiment including a display panel including a plurality of pixels each consisting of four sub-pixels.

The pixels (Pij, i = 1, 2, ..., j = 1, 2, ...) in the i row and j column are arranged in a matrix form on the display panel 110.

Each pixel Pij may be composed of four subpixels as shown in Figs. 2A to 3B. Each pixel Pij may be composed of four sub-pixels c1, c2, c3, and W including white sub-pixels W. [

As shown in FIGS. 2A to 3B, each pixel Pij includes a white subpixel W and three subpixels c1, c2, c3, and c3 when composed of four subpixels c1, c2, c3, c3 may be one of 24 combinations of red subpixel R, green subpixel G, and blue subpixel B. By including the white subpixels W in the four subpixels to form the pixels, the lifetime of the display device of the display device 100 can be improved and power consumption can be reduced.

At this time, one subpixel located inside of the subpixels constituting the specific first pixel may be defective. For example, as shown in FIGS. 2A to 3B, a white subpixel, which is the second subpixel or the third subpixel among the four subpixels (c1, c2, c3, W) constituting the M pixel, . At this time, the defects of the subpixels may vary. In the present specification, the defects of the subpixels are exemplarily described by the dark points (including the weak spot) of the subpixels, but the present invention is not limited thereto.

For example, as shown in FIGS. 2A and 2B, the white subpixel W positioned at the second of the subpixels c1, c2, c3, and W constituting the M pixels of the Mth column is defective (M + 1) -th column and the (M + 1) -th column of the white subpixel W positioned at the second position among the subpixels constituting the (M-1) The luminance of one or both of the white subpixels W positioned at the second of the subpixels can be increased. In other words, when the white subpixel W of M pixels in the Mth column is defective, the white subpixels W of the upper and lower pixels are raised and the luminance average of the white subpixels W of the M pixels of the Mth column, Can be increased.

In addition, the failure of the white subpixel W of M pixels in the Mth column can be compensated by the remaining subpixels (c1, c2, c3) constituting M pixels of the Mth column. In other words, by increasing the luminance of the remaining sub-pixels c1, c2 and c3 constituting M pixels in the Mth column, for example, red, green and blue subpixels, Failure can be compensated. As shown in FIG. 2B, depending on the efficiency of the target color coordinate (color temperature) and the display element OLED, it may not drive a specific sub-pixel when driving four sub-pixels. For example, when the color temperature of a pixel is high, the blue subpixel (blue display element) is mostly turned on and the subpixel to be turned off among the red subpixel (red display element) and the green subpixel have. As described above, when one of two subpixels adjacent to the first white subpixel constituting M pixels of the Mth column is not driven and the white first subpixel is defective, Can be driven to compensate for defects. At this time, the luminance of the white first subpixel and the adjacent subpixel driven to compensate can be lowered.

For example, as shown in FIGS. 3A and 3B, when the white subpixel W positioned at the third of the subpixels c1, c2, c3, and W constituting the M pixel is defective, Pixels constituting the white subpixel W positioned at the third among the subpixels constituting the (M-1) pixel and the (M + 1) th pixel of the (M + 1) The luminance of one or both of the white subpixels W positioned at the third position among the white subpixels W can be increased. When the white subpixels W of M pixels in the Mth column are defective, the white subpixels W of the upper and lower pixels are raised to raise the average luminance for the white subpixels W of the M pixels of the Mth column, .

At this time, the defects of the white subpixels W of M pixels of the Mth column can be compensated by the remaining subpixels (c1, c2, c3) constituting M pixels of the Mth column as described above. At this time, as shown in FIG. 3B, according to the efficiency of the target color coordinate (color temperature) and the display element OLED, one of the two sub-pixels adjacent to the white first sub-pixel constituting M pixels of the Mth column is not driven The first white subpixel may be driven to compensate for the failure of the first white subpixel when the white first subpixel is defective. At this time, the luminance of the white first subpixel and the adjacent subpixel driven to compensate can be lowered.

In general, when white first subpixel among the subpixels constituting the first pixel of the i-th row j (i, j is a natural number greater than 0) is defective, the i-th row jn column Of the sub-pixels constituting the first pixel of the i-th row and the third pixel of the i-th row of the (j + n) th column, The luminance of at least one of the third sub-pixels in the i-th row which is the same as one sub-pixel can be increased.

At this time, the defects of the first subpixel may be compensated for by one or more other subpixels constituting the first pixel of the i-th row j. For example, the red, green, and blue subpixels constituting the first pixel of the i-th row j column.

One of the two subpixels adjacent to the white first subpixel constituting the first pixel of the i-th row j-th column is not driven in accordance with the efficiency of the target color coordinate (color temperature) and the display element OLED, One subpixel may be driven to compensate for the failure of the white first subpixel if it is manifested as defective. At this time, the luminance of the white first subpixel and the adjacent subpixel driven to compensate can be lowered.

The configuration required for compensating defects through the brightness adjustment of the defective pixels and surrounding pixels will be briefly described with reference to FIG.

FIG. 4 is a configuration diagram for compensating for defects through brightness control of the display panel of the display device 100 according to the embodiments.

4, the display apparatus 100 according to the embodiment receives (RGB) ij input data for each pixel Pij in the i-th row j column and receives (RWGB) ij data (R ' W ' G ') ' of the defective pixels and surrounding pixels shown in Figs. 2A to 3B based on the defective information, B ') ij data to the data driver 120, and the like.

The data conversion unit 410 and the subpixel processing unit 420 shown in FIG. 4 may be included in the timing controller 140 or may be included outside the timing controller 140. 4, the data conversion unit 410 and the sub-pixel processing unit 420 are illustrated as being divided into two components, but they may be implemented as one component. In this case, the component in which the data conversion unit 410 and the sub-pixel processing unit 420 are integrated is a hardware or a software implementation that receives (i, j) input data (RGB) G 'B') ij data to the data driver 120.

As described above, the pixels Pij, i = 1, 2, ..., j (i, j) in the i-th row and j-th column composed of four sub-pixels c1, c2, c3, = 1, 2, ...) are compensated for by adjusting the brightness of a pixel having a defective pixel and peripheral pixels of the display panel 110 arranged in a matrix form will be described in detail.

5 is a panel configuration diagram of a display panel composed of RWGB subpixels.

Referring to FIG. 5, the display panel 110 of the display device 100 shown in FIG. 1 may be a display panel in which pixels arranged in the order of red, white, green, and blue subpixels are arranged in a matrix form. Twenty-four combinations are possible when each pixel is composed of four sub-pixels (c1, c2, c3, W) as described above with reference to Figs. 2A to 3B. At this time, the white subpixels are arranged in the second or third subpixel in consideration of chromaticity shift (light leakage), text readability, pixel aperture ratio, etc., so that the visibility of the pixels can be enhanced and the white balance can be improved. The remaining subpixels may be arranged in the remaining six combinations. As shown in FIG. 5, a white panel is arranged in a second sub-pixel, and a red, green, and blue sub-pixels are arranged in the remaining sub-pixels.

6, when the white subpixels arranged in the second subpixel of the M pixels of the Mth row and Nth column are expressed as dark points, white can be realized by utilizing the red, green, and blue subpixels of M pixels . Since the three red, green, and blue subpixels generated during the initial gamma setting are white, theoretically, the driving of the RWGB subpixels including white causes no dark spots of the white subpixels and the same color coordinates and luminance can do.

At this time, even if the RGB subpixels are driven to compensate the dark points of the white subpixels in the spatial arrangement, they can have characteristics easily recognizable to the human eye. In other words, if the arrangement is made in the order of RWBG subpixels, the dark spot visibility of white subpixels can be increased.

As shown in FIG. 6, when white subpixels arranged in the second subpixel of the M pixels of the Mth row in the Nth row are expressed as dark points, when white is implemented using the red, green, and blue subpixels, Or more green light may appear. In particular, one of the sub-pixels adjacent to the white sub-pixel disposed in the second sub-pixel of the M-th pixel in the Mth column according to the efficiency of the target color coordinate (color temperature) and the display element OLED, The white subpixels may be defective and may be driven to compensate for the dark points of the white subpixels. At this time, there may be a problem in that the red subpixel that increases the hazard brightness as compensation becomes too red (or reddish) due to the spatial arrangement adjacent to the subpixels of the dark spot and the non-driving subpixels.

In the following embodiments, when a white subpixel is expressed as a dark point, other than the other subpixels included in the same pixel as the corresponding white subpixel of the dark point, defective compensation driving can be performed using pixels above and below, such as adjustment of luminance or gamma value. When the upper and lower pixels such as the luminance or the gamma value are used in addition to the other subpixels contained in the same pixel as the corresponding white subpixel of the dark point, the color coordinates of the defective pixel corresponding to the vertical brightness of each subpixel are optically Compensate.

Referring to FIGS. 7A to 10, the display panels of the display device according to the embodiments in which the white subpixels positioned at the second position of the pixel are displayed as dark points and the subpixels adjacent to the dark point are not brightened Explain.

As shown in FIG. 7A, each of the plurality of pixels of the display panel 110 is configured in the order of red, white, green, and blue sub-pixels. At this time, depending on the efficiency of the target color coordinate (color temperature) and the display element OLED, it may not drive the specific sub-pixel when driving four sub-pixels. For example, when the color temperature of a pixel is high, the blue subpixel (blue display element) is mostly turned on and the subpixel to be turned off among the red subpixel (red display element) and the green subpixel have. 7 illustrates an example in which red subpixels are not driven, but the present invention is not limited thereto and all the subpixels may be driven.

When the white subpixels located at the second subpixel among the subpixels constituting the first pixel (Mpixel) are expressed as dark points, the (M-1) th column of the (M-1) The white subpixel W positioned at the second of the subpixels constituting the pixel and the second subpixel W (M + 1) of the subpixels constituting the (M + 1) ) All increase the brightness of 710. In other words, when the white subpixel W of M pixels in the Mth column is defective, the white subpixels W of the upper and lower pixels are raised and the luminance average of the white subpixels W of the M pixels of the Mth column, .

In addition, the defects of the white subpixels W of M pixels of the Mth column can be compensated by the remaining subpixels 700 constituting M pixels of the Mth column. At this time, one of the subpixels adjacent to the white subpixel disposed in the second subpixel of the M pixel pixel in the Mth column according to the efficiency of the target color coordinate (color temperature) and the display element OLED, for example, The white subpixels are defective and can be driven to compensate for the dark points of the white subpixels. At this time, the red subpixel having increased the gray level of the compensation is lowered so that the white subpixel of the dark point and the subpixels not driven are not more red due to the spatial arrangement adjacent to the dark point. At this time, the luminance of the green and blue subpixels other than the red subpixel can be also lowered at the same ratio to match the white balance.

When the luminance of the red, green, and blue subpixels 700 is lowered and the luminance of the upper and lower subpixels 710 of the white subpixel of the dark point is increased, the luminance of the pixel adjacent to the pixel in the pixel including the defective white subpixel The red component of the red subpixel is indicated by a dotted circle in FIG. 7B. At this time, the luminance of the upper and lower sub-pixels 710 of the white sub-pixel of the dark point is increased by the lowered luminance of the red, green, and blue sub-pixels 700 so that the red color does not appear too bright can do.

As shown in FIG. 8, each of the plurality of pixels of the display panel 110 is configured in the order of red, white, green, and blue subpixels. 8, the red subpixel is driven and the white subpixel disposed at the second subpixel of the M pixel pixel in the Mth column and the green subpixel adjacent to the right are driven in accordance with the efficiency of the target color coordinate (color temperature) and the display element OLED But the white subpixel is expressed as a dark spot and can be driven to compensate for the dark spot of the white subpixel. At this time, the luminance of the red subpixel is lowered so that the green subpixel that has increased in the compensation luminance becomes less red due to the white subpixel of the dark point and the adjacent spatial arrangement of the non-driving subpixels. At this time, the luminance of the green and blue subpixels other than the red subpixel can be also lowered at the same ratio to match the white balance.

When the luminance of the red, green, and blue subpixels 700 is lowered and the luminance of the upper and lower subpixels 710 of the white subpixel of the dark point is increased, the luminance of the pixel adjacent to the pixel in the pixel including the defective white subpixel The red component of the red subpixel is indicated by a dotted circle in FIG. 7B. The luminance of the upper and lower subpixels 810 of the white subpixel of the dark point is increased by the lowered luminance of the red, green, and blue subpixels 800 so that the green does not appear too bright .

The white subpixel adjacent to the dark point and the subpixel adjacent to the dark point are not limited to the red or green subpixels as shown in FIGS. 7A and 8A, and various combinations as described with reference to FIGS. 2A to 3B are possible.

9 and 10, by increasing the luminance of the upper and lower sub-pixels 910 of the white sub-pixel of the dark point by the lowered luminance of the red, green, and blue sub-pixels 900, The number of the upper and lower subpixels of the white subpixel may be two or more when the subpixel does not appear too bright. (M-1) th pixel in the (M-1) th column and the (M-2) th pixel in the (M-2) th column and the (M + Pixels of the (M + 2) -th column and the (M + 2) -th column of the (M + 2)

The number of the upper and lower subpixels 910 of the dark subpixel of the dark point for compensating the dark point is shown as four in FIG. 9, but it may be more than four or less than four. For example, the dark point can be compensated only with the subpixels above the white subpixel of the dark spot, and the dark point with only the lower subpixels. Also, the number of upper subpixels and the number of lower subpixels for compensating the white subpixels of a dark spot may be different. For example, one can compensate for the white subpixel of a dark spot with two subpixels at the top and one subpixel at the bottom.

At this time, in the case of two or more upper and lower subpixels, the luminance of the subpixel adjacent to the dark point and the subpixel adjacent to the dark point may be greatly increased, and the luminance may be increased as the distance is gradually increased. Thus, when the luminance of the white subpixels on the upper and lower sides of the white subpixel of the dark point is raised, it can be prevented from appearing as a weak luminance point.

As shown in FIG. 10, when driving all the subpixels and raising the luminance of the red subpixels located to the left of the white subpixels of the dark point to compensate for the dark points of the white subpixels when the white subpixels are defective, The luminance of the upper and lower red subpixels of the red subpixel can also be increased. At this time, in the case of two or more upper and lower subpixels, the white subpixel adjacent to the dark point is greatly increased in brightness, and the red subpixel located on the left side of the dark subpixel, The luminance can be greatly increased as the adjacent upper and lower red subpixels are increased, and the luminance can be increased as the luminance is further increased. Accordingly, the luminance of the red subpixels as well as the white subpixels of the top and bottom can be increased, thereby reducing the readiness of bad white subpixels.

In this case, in order to compensate for defective subpixels in the embodiments described with reference to FIGS. 7 to 10, a color coordinate compensation algorithm based on the luminance increase of the upper and lower subpixels of the defective subpixel can be applied. Since the color coordinate compensation algorithm by the luminance increase of the upper and lower subpixels of the defective subpixel is applied, the color coordinates of the defective pixel corresponding to the upper and lower luminance of each subpixel are optically compensated to meet the target value.

Referring to FIGS. 7 to 10, when the second or third white subpixel of a specific pixel is expressed as a dark point, the subpixel processing unit 420 described with reference to FIG. 4 processes the input (RWGB) ij data (R 'W' G 'B') ij data to the data driver 120. Therefore, when white subpixels are expressed as dark points, the first through third pixels are controlled in luminance through ij data (R 'W' G 'B') for dark point compensation that is not basic (R W G B) ij data.

Although the white subpixel is described as being located inside a specific pixel in the above-described embodiments, the present invention is not limited to this and may be located at the outermost side of a specific pixel.

In addition, although a dark spot, which is one of defects in the above embodiments, is mainly described, the present invention is not limited thereto and the present invention can be applied to any defects requiring brightness compensation.

When the specific white subpixel of the pixel is expressed as a defect such as a dark spot through the above-described embodiments, the luminance of the subpixels of the other colors is lowered and the luminance of the upper and lower subpixels of the defective white subpixel is increased, Can be prevented from appearing too bright. This makes it possible to improve the visibility of the display device.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. , Separation, substitution, and alteration of the invention will be apparent to those skilled in the art. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
