Accordingly, the present embodiments provide a display device capable of improving the completeness of the defect compensation by performing defect compensation by adjusting the luminance of a pixel in which defect is implemented and surrounding pixels, and a driving method thereof.

First, a display device of a display panel including a plurality of pixels each composed of RGB subpixels will be briefly described with reference to FIGS. 2A and 2B, and then, a plurality of pixels each composed of RWGB subpixels are included. The display device of the display panel will be briefly described.

2A and 2B illustrate a display device according to an exemplary embodiment including a display panel including a plurality of pixels each composed of RGB subpixels. 3A and 3B illustrate a display device according to another exemplary embodiment including a display panel including a plurality of pixels each composed of RWGB subpixels.

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

Each pixel Pij may be composed of three subpixels c1, c2, and c3 as shown in FIGS. 2A and 2B, and as shown in FIGS. 3A and 3B, four subpixels ( It may be composed of c1, c2, c3, c4).

2A and 2B, when each pixel Pij is composed of three subpixels c1, c2, c3, three subpixels c1, c2, c3 are red subpixel R , It may be one of six combinations of a green subpixel (G) and a blue subpixel (B). For example, the three subpixels c1, c2, and c3 may be a red subpixel R, a green subpixel G, and a blue subpixel B.

3A and 3B, when each pixel Pij is composed of four subpixels c1, c2, c3, and c4, four subpixels c1, c2, c3, and c4 are red subpixels. It may be one of 24 combinations of the pixel R, the green subpixel G, and the blue subpixel B, and the white subpixel W. Since a pixel is composed of four subpixels, the lifespan of the display device of the display device 100 can be improved and power consumption can be reduced.

At this time, one of the subpixels constituting the specific first pixel may be expressed as a defect. For example, as shown in Figs. 2A and 2B, the subpixel c2 located in the middle of the three subpixels c1, c2, c3 constituting the Nth pixel is expressed as a defect or three subpixels The second sub-pixel c2 or the third sub-pixel c3 among the c1, c2, c3, and c4 may be expressed as a defect. In this case, the defects of the subpixels may vary. In this specification, the defects of the subpixels are exemplarily described as dark spots (including weak dark spots) of the subpixels, but the present invention is not limited thereto.

For example, as shown in FIG. 2A, when one subpixel c2 located in the middle of the subpixels c1, c2, c3 constituting N pixels is expressed as a defect, the defective subpixel c2 N pixels may be represented by one sub-pixel (c3) positioned to the right of) and one sub-pixel (c1) formed in the (N+1) pixel. One subpixel (c1) located to the left of the defective subpixel (c2) and three subpixels (c1, c2, c3) constituting the (N-1) pixel can represent the (N-1) pixel. I can. The (N+1) pixel may be expressed by the remaining two subpixels (c2, c3) excluding one subpixel (c1) configured in the (N+1) pixel representing N pixels. In this case, N pixels correspond to first pixels, (N+1) pixels correspond to second pixels, and (N-1) pixels correspond to third pixels.

As another example, as shown in FIG. 2B, if one subpixel c2 located in the middle of the subpixels c1, c2, c3 constituting N pixels is expressed as a defect, the defective subpixel c2 The N-th pixel may be expressed by one subpixel c1 positioned to the left of) and one subpixel c3 formed in the (N-1) pixel. The (N+1) pixel can be represented by three sub-pixels (c1, c2, c3) constituting one sub-pixel (c3) and (N+1) pixel located to the right of the defective sub-pixel (c2). I can. The (N-1) pixel may be represented by the remaining two subpixels c1 and c2 except for one subpixel c3 configured in the (N-1) pixel representing the N pixel. In this case, N pixels correspond to first pixels, (N-1) pixels correspond to second pixels, and (N+1) pixels correspond to third pixels.

As another example, as shown in Fig. 3A, if one subpixel (c2) located in the second of the subpixels (c1, c2, c3, c4) constituting N pixels is expressed as a defect, The N-th pixel may be represented by two subpixels c3 and c4 positioned to the right of the subpixel c2 and one subpixel c1 formed in the (N+1) pixel. Three subpixels (c2, c3, c4) or four subpixels (c1, c2) constituting one subpixel (c1) and (N-1) pixel positioned to the left of the defective subpixel (c2) , c3, c4) can represent (N-1) pixels. The (N+1) pixel may be represented by the remaining three subpixels (c2, c3, c4) excluding one subpixel (c1) configured in the (N+1) pixel representing N pixels. In this case, N pixels correspond to first pixels, (N+1) pixels correspond to second pixels, and (N-1) pixels correspond to third pixels.

As another example, as shown in FIG. 3B, when one subpixel (c3) located at the third of the subpixels (c1, c2, c3, c4) constituting N pixels is expressed as a defect, The N-th pixel may be represented by one subpixel c4 configured in two subpixels c1 and c2 positioned to the left of the subpixel c3 and a pixel (N-1). Three subpixels (c1, c2, c3) or four subpixels (c1) constituting one subpixel (c4) and (N+1) pixel positioned to the right of the defective subpixel (c3) (N+1) pixels can be represented by c2, c3, c4). The (N-1) pixel may be expressed by the remaining three subpixels (c1, c2, c3) excluding one subpixel (c4) configured in the (N-1) pixel representing N pixels. In this case, N pixels correspond to first pixels, (N-1) pixels correspond to second pixels, and (N+1) pixels correspond to third pixels.

In general, when one of the subpixels constituting a specific first pixel is expressed as a defect, one or more subpixels located on one side of the defective subpixel and the first pixel are adjacent to one side. The first pixel may be represented by one or more subpixels configured in the second pixel. In addition, the third pixel may be represented by one or more sub-pixels positioned on the other side of the defective sub-pixel, and one or more sub-pixels constituting the first pixel and the third pixel adjacent to the other side. In addition, the second pixel may be expressed with one or more subpixels excluding one or more subpixels configured in the second pixel representing the first pixel.

In other words, if one of the subpixels constituting a specific first pixel is expressed as a dark spot, a person will be able to express the second and third pixels located on both sides of the first pixel and the first pixel. The first to third pixels can be expressed in units of pixels that are actually recognized.

When the defect is compensated by adjusting the luminance of the pixel in which the above-described defect is implemented and the surrounding pixels, a necessary configuration will be briefly described with reference to FIG. 4.

4 is a diagram illustrating a configuration of compensating for defects by adjusting luminance of a display panel of the display device 100 according to exemplary embodiments.

Referring to FIG. 4, the display device 100 according to embodiments includes a data conversion unit 410 that receives (RGB)i input data and converts it into (RWGB)i data, and (RWGB)i data is received and the (R' W'G'B')i data of the pixels in which the defects shown in Figs. 2A to 3B are implemented and surrounding pixels are transferred to the data driver 120 based on the defect information. And a subpixel processing unit 420 to output.

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. In addition, although FIG. 4 shows that the data conversion unit 410 and the subpixel processing unit 420 are implemented by dividing into two components, they may be implemented as one component. In this case, the component in which the data conversion unit 410 and the subpixel processing unit 420 are integrated receives (RGB)i input data through hardware or software implementation, and the defective pixel and (R'W') G'B')i data may be output to the data driver 120.

As described above, as shown in FIGS. 3A and 3B, pixels in row i and j columns (Pij, i=1, 2, ..., j) are composed of four subpixels (c1, c2, c3, c4). =1, 2, ...) will be described in detail in embodiments in which the display panel 110 in which the display panel 110 is arranged in a matrix form is exemplified and compensates for the defect by adjusting the luminance of the pixels and surrounding pixels.

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 illustrated in FIG. 1 may be a display panel in which pixels formed in the order of red, white, green, and blue subpixels are arranged in a matrix form. As described above with reference to FIGS. 3A and 3B, when each pixel is composed of four subpixels c1, c2, c3, and c4, 24 combinations are possible. At this time, since the white subpixel is disposed in the second or third subpixel in consideration of color coordinate shift (light leakage), text readability, and pixel aperture ratio, the visibility of the pixel can be improved and white balance can be improved. The remaining subpixels may be arranged in six combinations on the other. As illustrated in FIG. 5, a display panel 110 in which white subpixels are disposed on the second subpixel and red, green, and blue subpixels are disposed on the remaining subpixels will be described as an example.

In this case, as shown in FIG. 6, when a white subpixel disposed in the second subpixel of the N pixel is expressed as a dark spot, white may be implemented by utilizing the red, green, and blue subpixels of the N pixel. Since white is implemented by the three subpixels generated when the initial gamma is set, in theory, the color coordinates and luminance may be the same as when the dark spot of the white subpixel is not expressed by driving the RWGB subpixels including white.

At this time, even if the RGB subpixels are driven to compensate for dark spots of the white subpixels by spatial arrangement, they may have features that are easy to recognize by the human eye. In other words, when the RWBG subpixels are arranged in the order, the visibility of dark spots of the white subpixels may increase.

As shown in FIG. 6, when white is implemented with three subpixels generated when initial gamma is set as white unit pixels 600, 610, and 620, as shown in FIG. , 620) and the white realization unit pixels 700, 710, and 720 that are actually perceived by a person may cause a feeling of heterogeneity/existence. In other words, when a white subpixel is expressed as a dark spot, the corresponding white unit pixel 610 is the three subpixels set when the gamma is set, as shown in FIG. 6, but the white subpixel located in the second subpixel becomes a dark spot. Since it is expressed, the actual perceived white unit pixel is divided into both sides 700 and 710 of the white subpixels expressed as dark spots.

In this case, the quality of the display panel 110 is degraded and the immersion feeling is hindered when the user views the display panel 110.

Hereinafter, with reference to FIGS. 8 to 11, when the second or third white subpixel of the pixel is expressed as a dark spot, the white realization unit pixel and the white realization unit pixel that are actually recognized by a person are matched to give a sense of foreign body/different texture when viewing. Display panels of a display device according to exemplary embodiments will be described in detail.

As shown in FIG. 8, each of a plurality of pixels of the display panel 110 is configured in order of red, white, green, and blue subpixels. In this case, when the four subpixels are driven according to the target color coordinate (color temperature) and the efficiency of the display device (OLED), a specific subpixel may not be driven. For example, when the color temperature of a pixel is high, most of the blue sub-pixels (blue display device) are turned on, and the sub-pixel to be turned off among the red sub-pixels (red display device) and the green sub-pixel (green display device) can be determined through RGB data operation. have. In FIG. 8, a case in which the red subpixel is not driven is exemplarily described, but the present invention is not limited thereto, and all subpixels may be driven.

At this time, if the white subpixel located in the second subpixel among the subpixels constituting the first pixel (N pixel) is expressed as a dark spot, the white unit pixel (800, 810, 820) and the white realization recognized by humans Each pixel is represented by matching the unit pixels 700, 710, and 720.

For example, if a white subpixel located in the second subpixel among the subpixels constituting the first pixel (N pixel) is expressed as a dark spot, the red subpixel and the second pixel ((N+1) pixel) A first pixel (N pixel) is represented by green and blue subpixels of 1 pixel (N pixel). In addition, the second pixel ((N+1) pixel) is represented by the remaining white, green, and blue subpixels of the second pixel ((N+1) pixel), and the red subpixel and the first pixel (N pixel) are A third pixel ((N-1) pixel) may be represented by white, green, and blue subpixels of 3 pixels ((N-1) pixel). As described above, the red subpixel may not be driven in the third pixel, but the present invention is not limited thereto, and the red subpixel may also be driven.

As shown in FIG. 9, each of the plurality of pixels of the display panel 110 is composed of red, white, green, and blue subpixels in order. 9 illustrates a case in which the red subpixel is driven and the green subpixel is not driven, but the present invention is not limited thereto, and all subpixels may be driven.

At this time, when the white subpixel located in the second subpixel among the subpixels constituting the first pixel (N pixel) is expressed as a dark spot, the white unit pixel 900, 910, 920 and the white realization recognized by humans Each pixel is represented by matching the unit pixels 700, 710, and 720.

For example, if a white subpixel located in the second subpixel among the subpixels constituting the first pixel (N pixel) is expressed as a dark spot, the red subpixel and the second pixel ((N+1) pixel) A first pixel (N pixel) is represented by green and blue subpixels of 1 pixel (N pixel). In addition, the second pixel ((N+1) pixel) is represented by the remaining white, green, and blue subpixels of the second pixel ((N+1) pixel). A third pixel ((N-1) pixel) is represented by a red subpixel of the first pixel (N pixel) and white, green, and blue subpixels of the third pixel ((N-1) pixel).

As shown in FIGS. 10 and 11, each of a plurality of pixels of the display panel 110 is configured in order of red, green, white, and blue subpixels. When a white subpixel located in the third subpixel among the subpixels constituting the first pixel (N pixel) is expressed as a dark spot, the white unit pixel (1000, 1010, 1020) and the white unit that is actually recognized by a person Each pixel is represented by matching the pixels 700, 710, and 720.

For example, if a white subpixel positioned in the third subpixel among the subpixels constituting the first pixel (N pixel) is expressed as a dark spot, the blue subpixel and the second pixel ((N-1) pixel) A first pixel (N pixel) is represented by red and green subpixels of 1 pixel (N pixel). In addition, the second pixel ((N-1) pixel) is represented by the remaining red, green, and white subpixels of the second pixel ((N-1) pixel). The blue subpixel of the first pixel (N pixel) and the red, green, and white subpixel of the third pixel ((N+1) pixel) as shown in FIG. 10 or the third pixel as shown in FIG. A third pixel is represented by red, green, white, and blue subpixels.

When a white subpixel positioned at the second or third position of the pixel is expressed as a dark spot with reference to FIGS. 8 to 11, a white realization unit pixel is actually recognized by a person to represent the first to third pixels. The subpixel processing unit 420 described with reference to FIG. 4 processes the input RWGB data so as to coincide with FIG. 4 and outputs the R'W'G'B'data to the data driver 120. Therefore, when white subpixels are expressed as dark spots, the first to third pixels are controlled in luminance through R'W'G'B' data for dark spot compensation rather than basic R W G B data.

The embodiments described with reference to FIGS. 8 to 11 exemplarily describe four subpixels arranged at specific positions of red, white, green, and blue, but positions of each subpixel are described with reference to FIGS. 3A and 3B. As shown, all 24 combinations are possible. In addition, although the embodiments described with reference to FIGS. 8 to 11 exemplarily described four sub-pixels, as described with reference to FIGS. 2A and 2B, a display panel including a plurality of pixels composed of three sub-pixels The same can be applied to In addition, even when one pixel is composed of five or more subpixels, when a white subpixel located inside the pixel is expressed as a dark spot, a person actually recognizes a white unit pixel to represent the first to third pixels. The subpixel processing unit 420 described with reference to FIG. 4 processes the input RWGB data so as to coincide with the white unit pixel, and outputs the R'W'G'B'data to the data driver 120.

Through the above-described embodiments, when a specific sub-pixel located inside a pixel is expressed as a defect such as a dark spot, the white unit pixel and the white unit pixel that is actually recognized by a person are matched so that the sense of foreign body/different texture is not reduced when viewing. It works. Through this, the visibility of the display device can be improved.
