4 illustrates a driving method used to reproduce an image having an FHD resolution in a lenticular stereoscopic display device according to an exemplary embodiment of the present invention.

As illustrated in FIG. 4, in order to describe in detail a method of driving a lenticular stereoscopic display device according to an exemplary embodiment of the present invention, pixel groups PG1, PG2, PG3, PG4, PG5, PG6, PG7, PG8). Here, each pixel group PGn includes a reference pixel Pn0, a first expansion pixel Pn1, a second expansion pixel Pn2, and a third expansion pixel Pn3. In this case, each pixel includes an R unit pixel, a G unit pixel, and a B unit pixel. The reference pixel Pn0 located in the pixel group PGn receives an original video signal at a corresponding position of an image recorded at a resolution of a given FHD. Therefore, the reference pixel Pn0 is represented in the same manner as the gray level of the original video signal having the FHD resolution. Here, the gray scale refers to a numerical value of contrast which one pixel receives and represents an original video signal or an extended video signal. Meanwhile, the first extended pixel Pn1 receives an extended video signal generated according to the original video signal of the adjacent reference pixel Pn0, which will be described using the first pixel group as an example.

The first expansion pixel P11 located in the first pixel group PG1 according to the exemplary embodiment of the present invention is located on the right side of the reference pixel P10 and is the reference pixel P10 of the first pixel group PG1. And the reference pixel P20 of the second pixel group PG2 are adjacent to each other. In this case, the gray level of the extended image signal applied to the first extended pixel P11 of the first pixel group PG1 is based on the reference pixel P10 and the second pixel group PG2 of the first pixel group PG1. The gray level average of the original image signal applied to the pixel P20 is determined. For example, the gray level of the R subpixel configured in the reference pixel P10 of the first pixel group PG1 is 0, and the gray level of the R subpixel configured in the reference pixel P20 of the second pixel group PG2 is 255. In the case of, the gray level of the R subpixels configured in the first extended pixel P11 of the first pixel group PG1 is allocated to 127 or 128 which are averages thereof.

Meanwhile, the first extended pixel P21 positioned in the second pixel group PG2 according to the exemplary embodiment of the present invention may be the reference pixel P20 of the second pixel group PG2 and the reference pixel of the first pixel group PG1. (P10), the reference pixel P30 of the third pixel group PG3 and the reference pixel P40 of the fourth pixel group PG4 are adjacent to each other. In this case, the gray level of the extended video signal applied to the first extended pixel P21 of the second pixel group PG2 is determined by the reference pixel P20 and the third pixel group PG3 of the second pixel group PG2. A first weight obtained by multiplying each gray level of the original image signal applied to the reference pixel P30 by a predetermined multiple, and the reference pixels P10 of the first pixel group PG1 and the reference pixels of the fourth pixel group PG4. The gray level may be calculated by adding the second weights obtained by subtracting each of the gray levels of the original video signal applied to (P40). According to the setting of the view map of the display device, the weight of the gray level of the reference image signal P20 of the second pixel group PG2 and the reference pixel P30 of the third pixel group PG3 is increased. The weights of the original image signals of the reference pixel P10 of the first pixel group PG1 and the reference pixel P40 of the fourth pixel group PG4 may be lowered and mixed. The gray level calculated as described above is divided by the sum of the weight ratios for each pixel position, so that the gray level can be expressed similarly to the gray levels of the neighboring reference pixels P20 and P30.

For example, the gray level of the R subpixel configured in the reference pixel P10 of the first pixel group PG1 is 30, and the gray level of the R subpixel configured in the reference pixel P20 of the second pixel group PG2 is 80. When the gray level of the R sub pixel configured in the reference pixel P30 of the third pixel group PG3 is 230 and the gray level of the R sub pixel configured in the reference pixel P40 of the fourth pixel group PG4 is 23. The gray level of the R subpixel configured in the first extended pixel P21 of the second pixel group PG2 is calculated as 567 when the weight is -1: 2: 2: -1. In this case, the calculated value 567 is calculated as 283 or 284 when divided by the sum of the weight ratios for each pixel position. In this case, the calculated value is assigned to 255 since the maximum gray level is 255 or more.

As described above, when the extended video signal of the first extended pixel Pn1 is two adjacent reference pixels P10 and P20 like the first pixel group PG1, the extended video signal is calculated as a gray average of the respective original video signals, or When there are four adjacent reference pixels P10, P20, P30, and P40 like the second extended pixel PG2, the gray scales are calculated by mixing the respective original video signals according to a set weight. The gray level of the extended image signal applied to (Pn1) is a weight of -1: 2: 2:-for the gray level of the original image signal applied to each of the reference pixels Pn0 of the first to fourth pixel groups PG1 to PG4. After calculating by mixing so that it becomes 1, it can express by dividing by the sum of each weight ratio.

Meanwhile, the extended image signal applied to the second extended pixel Pn2 is generated according to the original video signal of the reference pixel Pn0 adjacent to the second extended pixel Pn2, which is located in the second pixel group PG2. The two extended pixels P22 will be described as an example.

The second extended pixel P22 of the second pixel group PG2 according to an exemplary embodiment of the present invention is positioned below the reference pixel P20 of the second pixel group PG2. The extended image signal applied to the second extended pixel P22 of the grayscale of the original video signal applied to the reference pixel P20 of the second pixel group PG2 and the reference pixel P60 of the sixth pixel group PG6. Determined on average. For example, the gray level of the R subpixel configured in the reference pixel P20 of the second pixel group PG2 is 80, and the gray level of the R subpixel configured in the reference pixel P60 of the sixth pixel group PG6 is 180. In this case, the gray level of the R subpixels configured in the second extended pixel P22 of the second pixel group PG2 is set to 130, which is an average thereof.

As described above, the extended image signal generated by mixing the original image signal applied to the two neighboring reference pixels Pn0 is applied to the second extension pixel Pn2, and the second and sixth pixel groups PG2 and PG6 are respectively applied. The gray level of the original video signal applied to the reference pixels P20 and P60 of the Mn may be mixed and the average value may be calculated as the gray level of the extended video signal.

On the other hand, since the third expansion pixel Pn3 is located in a diagonal direction with the reference pixel Pn0, instead of mixing the original video signal of the reference pixel Pn0, the third expansion pixel Pn3 may be configured to use the expansion video signal of the first expansion pixel Pn1 calculated first. Can be calculated by mixing. The gray level average of the extended image signal of the first extended pixel Pn1 positioned up and down adjacent to the third extended pixel Pn3 in the pixel group PGn may be calculated as the extended video signal of the third extended pixel Pn3. The third expansion pixel P23 of the second pixel group PG2 will be described as an example.

The third expansion pixel P23 of the second pixel group PG2 according to the exemplary embodiment of the present invention is the first expansion pixel P21 of the second pixel group PG2 and the first expansion of the sixth pixel group PG6. It is adjacent to the pixel P61. In this case, the extended image signal applied to the third expansion pixel P23 of the second pixel group PG2 may include the first expansion pixel P21 and the sixth pixel group PG6 of the second pixel group PG2. It is determined by the gradation average of one extended pixel P61. For example, the gray level of the R subpixel configured in the first extended pixel P21 of the second pixel group PG2 is 80, and the R subpixel configured in the first extended pixel P61 of the sixth pixel group PG6. When the gray level of is 180, the gray level of the R subpixels configured in the third extended pixel P13 of the second pixel group PG2 is set to 130, which is an average thereof.

As described above, the third extension pixel Pn3 displays the gray level by mixing the extension video signals represented by two neighboring first expansion pixels Pn1, and respectively displays the second and sixth pixel groups PG2 and PG6. It is preferable to mix the gray scales of the first extended pixel Pn1 of and to display the average value in gray scales.

When the first to third expansion pixels Pn1 to Pn3 are represented as described above, the second and third expansion pixels Pn2 and Pn3 formed at the lower end of the lenticular stereoscopic display device and the first expansion pixels formed at the right end thereof. This driving method cannot be used because Pn1 has only one neighboring reference pixel. The method used in this case will be described with reference to FIG. 5 below.

FIG. 5 illustrates a driving method used to reproduce an FHD resolution image at an end of a lenticular stereoscopic display device having a UD resolution panel according to an exemplary embodiment of the present invention.

As illustrated in FIG. 5, two or more neighboring reference pixels are required for the first to third extended pixels P91 and P01 to P03 of the ninth pixel group PG9 and the tenth pixel group PG0. Since there are no reference pixels P90 and P00 positioned in the same pixel group, calculation by weight is impossible. The first to third expansion pixels Pn1 to Pn3 formed at such positions are the first to third expansion pixels (Pn1 to FIG. 4) positioned in the first to eight pixel groups (PG1 to PG8 of FIG. 4) of FIG. 4. It is calculated differently from the method of obtaining the gradation of Pn3).

As illustrated in FIG. 5, the first expansion pixel P91 of the ninth pixel group PG9 according to the exemplary embodiment of the present invention is adjacent to only one reference pixel P90 of the ninth pixel group PG9. In this case, the gray level of the first extended pixel P91 may be set to be the same as the gray level of the reference pixel P90. For example, when the gray level represented by the reference pixel P90 of the ninth pixel group PG9 is 170, the first expansion pixel P91 may display 170, which is the same gray level as the reference pixel P90, and may cause inconvenience in viewing. It is driven so that there is no box.

On the other hand, in the case of the second extended pixel P02 of the tenth pixel group PG0, since only one reference pixel P00 is adjacent to each other, the gray level of the second extended pixel P02 may also be the first extended pixel P91 described above. It can be set in the same manner as the gradation of. For example, when the gray scale represented by the reference pixel P00 of the tenth pixel group PG0 is 63, the second extended pixel P02 may display 63, which is the same gray scale as the reference pixel P00, so that viewing is inconvenient. It is driven so that there is no.

In addition, in the case of the third expansion pixel P03 of the tenth pixel group PG0, since only one first expansion pixel P01 is adjacent to each other, the gray level of the third expansion pixel P03 may also be the first expansion pixel ( P91) can be set in a similar manner. For example, when the gray scale represented by the first extended pixel P01 of the tenth pixel group PG0 is 48, the third extended pixel P03 has the same gray level as that of the first extended pixel P01. It is driven so that there is no inconvenience in viewing. In this case, the first expansion pixel P01 represents 48 which is the same gray level as the reference pixel P00.

As described above, when driving in accordance with the lenticular stereoscopic display device and the driving method thereof, the image signal lost by the lenticular lens unit is further compensated for the display gray level for each unit pixel. The effect of reducing the signal is obtained. Accordingly, when the planar image of the lenticular stereoscopic display device is driven, the screen with less damage to the image signal can be viewed.

In addition, while the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications of the present invention without departing from the spirit and scope of the present invention described in the claims below.
