Description

Image display driving method, device and device

The present application claims priority to Chinese Patent Application No. 201510190878.0, entitled "Image Display Driving Method, Apparatus and Apparatus", filed on April 21, 2015, the entire contents of In this application.

Technical field

The present invention relates to the field of image processing, and in particular, to an image display driving method, apparatus and device.

Background technique

At present, the traditional ultra-high definition display technology mainly includes RGB (red, green, blue) ultra high definition display technology and RGBW (red, green, blue, white) ultra high definition display technology. Among them, the RGBW ultra-high definition display technology adds a white sub-pixel to the conventional RGB three primary colors (ie, red, green, blue) to form an RGBW structure, that is, each pixel of the display device. Each consists of a red sub-pixel, a green sub-pixel, a blue sub-pixel (ie, a three-primary sub-pixel), and a white sub-pixel, and the brightness of different sub-pixels is adjusted by adjusting an operating voltage or current for driving different sub-pixels ( Also known as grayscale values), each pixel is ultimately rendered in a different color.

In the prior art, the RGBW structure has a plurality of different structures, such as a linear arrangement (which can also be a vertical strip arrangement), and a linear arrangement means that each pixel is provided with three primary color sub-pixels and white sub-pixels in the first direction. a pixel, in a second direction perpendicular to the first direction, two adjacent sub-pixels are sub-pixels that represent the same color.

When two pixels adjacent to each other need to display different colors, it is necessary to illuminate different sub-pixels of the adjacent two pixels, that is, to illuminate at most three sub-pixels of the first to fourth sub-pixels of the first pixel, and Lighting up to three sub-pixels of the first to fourth sub-pixels of the second pixel, so that the lit sub-pixels can be mixed to form different colors; however, from the hardware structure, the first sub-pixel of the first pixel (ie, the leftmost sub-pixel) and the fourth sub-pixel of the second pixel (ie, the rightmost sub-pixel) are far apart, when only the first sub-pixel in the first pixel emits light, and the second pixel When only the fourth sub-pixel emits light, a black dot (or black line) on the human eye is caused by the interval between the two non-illuminating sub-pixels.

For example, the prior art is described by taking a vertical bar type WRBG arrangement as an example. FIG. 1 is a schematic diagram showing a black line in a picture from yellow to white in the prior art. Referring to FIG. When the picture is yellow to white, the red sub-pixel and the green sub-pixel in the pixel for displaying the yellow color are far apart from the white sub-pixel in the pixel for displaying the white color (green sub-pixel and white sub-pixel) There are five non-lighting sub-pixels apart from each other. Therefore, it is easy to mistake five consecutive non-emitting sub-pixels as one black line from the perspective of human visual effects.

It can be seen that in the prior art, when a pixel of a special color needs to be presented, it is likely that a significant black line phenomenon occurs due to the arrangement of the sub-pixels in the pixel.

The embodiments of the present invention are specifically described below by taking an OLED adopting an RGBW structure as an example.

The embodiments of the present invention can be preferably applied to a vertical strip sub-pixel arrangement (also referred to as a vertical strip arrangement) or a similar arrangement.

When pixels displaying white color are adjacent to pixels of some special colors, in order to avoid black lines (or black dots) appearing in the image, the number of consecutive non-emitting sub-pixels is reduced, for example, by lighting a portion of the continuous non-emitting sub-pixels The sub-pixel method avoids the phenomenon of black lines, so that from the human eye, the area occupied by the non-illuminating sub-pixels is reduced, thereby making the black lines less visible to the human eye and avoiding image distortion. Phenomenon, which improves the display of images and enhances the user experience.

It should be noted that, in the above application scenario, in order to illuminate a portion of the sub-pixels in the continuous non-emitting sub-pixel, the brightness value of the original pixel can still be ensured, since the white light is in the form of a mixture of three primary colors,

In the embodiment of the present invention, part of the brightness of the white sub-pixel in the same pixel can be converted into a brightness which is proportionally mixed by the three primary colors, thereby reducing the area that does not emit light while ensuring that the image is not distorted.

When a pixel displaying a white color is adjacent to a pixel of some special color, that is, a sub-pixel in which the continuous gray scale is not zero includes a white sub-pixel. For example, when it is necessary to display a picture from white to yellow excessive, since the white sub-pixel in the pixel for displaying the white color is adjacent to the red sub-pixel and the green sub-pixel in the adjacent pixel for displaying the yellow color, and white The sub-pixel has high luminous efficiency. Therefore, from the perspective of the human eye, obvious white bright lines may appear; in order to avoid white lines (or white spots) appearing in the image, embodiments of the present invention can adjust adjacent or adjacent The gray scale range of the pixel, for example, by reducing the brightness of the continuous illuminating sub-pixels, reduces the brightness of the adjacent pixels, and weakens the phenomenon of white bright lines without losing the display area, thus, from the human eye vision In the above, the white bright line is not easily perceived by the human eye, and the phenomenon of image distortion is avoided, thereby improving the display effect of the image and improving the user experience.

It should be noted that, in the above application scenario, the gray scale range of the adjacent or adjacent pixels may be adjusted to be between 64 gray scales and 200 gray scales.

The following are examples of vertical strip type WRGB arrangement, vertical strip type WRBG arrangement, vertical strip type WGRB arrangement, vertical strip type WGBR arrangement, vertical strip type WBRG arrangement and vertical strip type WBGR arrangement, for special images. The improvement algorithm of the white line and the black line appearing in it is specifically described.

The image processing algorithm provided by the embodiment of the invention can convert the image signal of the signal end into the image signal of the display end. The image processing algorithm provided by the embodiment of the invention can also optimize the image signal that has been converted into the display end. In the embodiment of the present invention, the signal end may be an RGB signal transmitting end, and the display end may be various display devices.

It should be noted that, for convenience of description, in the embodiment of the present invention, the red sub-pixel is simply referred to as R or R sub-pixel, the green sub-pixel is simply referred to as G or G sub-pixel, and the blue sub-pixel is simply referred to as B or B. A sub-pixel, a white sub-pixel is simply referred to as a W or a W sub-pixel.

As a preferred embodiment, FIGS. 3(a) and (b) respectively show schematic diagrams of black and white lines in a vertical strip type WRGB arrangement provided by an embodiment of the present invention, and FIG. 3(c) shows The schematic diagram for optimizing the black line in the vertical strip type WRGB arrangement provided by the embodiment of the present invention is shown in FIGS. 3(a), (b) and (c), and the optimization algorithm may include:

FIG. 3(a) shows only four pixels, that is, first to fourth pixels, in which the red sub-pixel, the green sub-pixel, and the blue sub-pixel in the first pixel are not illuminated (ie, the grayscale value is equal to zero), The white sub-pixel emits light and the grayscale value is equal to 255, at which time the first pixel presents a white color.

The red sub-pixel, the green sub-pixel, and the blue sub-pixel in the second pixel are not illuminated (ie, the grayscale value is equal to zero), and the white sub-pixel is illuminated and the grayscale value is equal to 255, and the second pixel presents a white color.

The red sub-pixel and the green sub-pixel in the third pixel emit light, and the gray scale values of the red sub-pixel and the green sub-pixel emit light are equal to 255, and the blue sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero), At this time, the third pixel appears yellow.

Wherein the red sub-pixel and the green sub-pixel in the fourth pixel emit light and the gray scale values of the red sub-pixel and the green sub-pixel emit light are equal to 255, and the blue sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero), At this time, the fourth pixel appears yellow.

In a specific implementation, when a picture transitioning from white to yellow occurs, as shown by the direction of the arrow in FIG. 3(a), adjacent sub-pixels, that is, white sub-pixels of the second pixel and red sub-pixels of the third sub-pixel The green sub-pixel emits light at the same time, and a bright white line appears in the image.

For example, taking the 255 gray scale as an example, from the video signal end analysis, the 255 gray-scale W sub-pixel has 255 gray-scale RGB signals converted, so that only the W sub-pixel works at the display end; and for the 255 gray-scale The RG subpixels do not need to be converted, maintaining their original grayscale, so that only the RG subpixels (synthetic yellow) work on the display side.

In order to optimize the white line appearing in the image, the embodiment of the present invention reduces the brightness of three adjacent illuminating sub-pixels on the display end. Therefore, the video signal end is required to reduce the three RGB gray scale values corresponding to the W sub-pixel, which can be reduced to 200. The RG grayscale value corresponding to the RG sub-pixel can be reduced to 200.

3(b) shows only four pixels, that is, first to fourth pixels, in which the red sub-pixel and the green sub-pixel in the first pixel emit light and the gray scale values of the red sub-pixel and the green sub-pixel emit light are equal to 255. The blue sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero), and the first pixel presents a yellow color.

The red sub-pixel and the green sub-pixel in the second pixel emit light, and the grayscale values of the red sub-pixel and the green sub-pixel emit light are equal to 255, and the blue sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero), At this point the second pixel appears yellow.

The red sub-pixel, the green sub-pixel, and the blue sub-pixel in the third pixel are not illuminated (ie, the grayscale value is equal to zero), and the white sub-pixel is illuminated and the grayscale value is equal to 255, and the third pixel presents a white color.

The red sub-pixel, the green sub-pixel, and the blue sub-pixel in the fourth pixel are not illuminated (ie, the grayscale value is equal to Zero), while the white sub-pixel emits light and the grayscale value is equal to 255, at which time the fourth pixel presents a white color.

In a specific implementation, when a picture transitioning from yellow to white occurs, as shown by the direction of the arrow in FIG. 3(b), the adjacent sub-pixel, that is, the green sub-pixel of the second pixel and the white sub-pixel of the third sub-pixel are simultaneously The light is emitted and the distance between the two is 5 sub-pixels. At this time, a white black line appears in the image.

For example, referring to FIG. 3(c), the conversion rate of the grayscale signal of the W sub-pixel is adjusted. If the RGB grayscale is equal to 255, the grayscale of the converted RGB sub-pixel is equal to 55, and the grayscale of the W sub-pixel is equal to 200. The negative effects of the black line are weakened by the brightness adjustment of the four sub-pixels of WRGB.

It should be noted that the embodiment of the present invention is only described by using the above-mentioned conversion rate as an example. The embodiment of the present invention can also be optimized according to the actual conversion rate according to the actual conversion requirement. Generally, the conversion rate in the embodiment of the present invention may be between Between 30% and 80%, the manner and the algorithm for ensuring the display effect of the image are all within the protection scope of the embodiment of the present invention, and details are not described herein again.

As a preferred embodiment, FIG. 4(a) and (b) respectively show schematic diagrams of black and white lines in a vertical strip type WGRB arrangement provided by an embodiment of the present invention, and FIG. 4(c) shows The schematic diagram for optimizing the black line in the vertical strip type WGRB arrangement provided by the embodiment of the present invention, as shown in FIGS. 4(a), (b) and (c), the optimization algorithm may include:

4(a) shows only four pixels, that is, first to fourth pixels, in which the green sub-pixel, the red sub-pixel, and the blue sub-pixel in the first pixel are not illuminated (ie, the grayscale value is equal to zero), The white sub-pixel emits light and the grayscale value is equal to 255, at which time the first pixel presents a white color.

The green sub-pixel, the red sub-pixel, and the blue sub-pixel in the second pixel are not illuminated (ie, the grayscale value is equal to zero), and the white sub-pixel is illuminated and the grayscale value is equal to 255, and the second pixel presents a white color.

The green sub-pixel and the red sub-pixel in the third pixel emit light, and the gray scale values of the green sub-pixel and the red sub-pixel emit light are equal to 255, and the blue sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero). At this time, the third pixel appears yellow.

The green sub-pixel and the red sub-pixel in the fourth pixel emit light, and the gray scale values of the green sub-pixel and the red sub-pixel emit light are equal to 255, and the blue sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero). At this time, the fourth pixel appears yellow.

In a specific implementation, when a picture transitioning from white to yellow occurs, as shown by the direction of the arrow in FIG. 4(a), adjacent sub-pixels, that is, white sub-pixels of the second pixel and green sub-pixels of the third sub-pixel The red sub-pixels are illuminated at the same time, and a bright white line appears in the image.

For example, taking the 255 gray scale as an example, from the video signal end analysis, the 255 gray-scale W sub-pixel has 255 gray-scale RGB signals converted, so that only the W sub-pixel works at the display end; and for the 255 gray-scale The GR sub-pixels do not need to be converted, maintaining their original grayscale, so that only the GR sub-pixels (synthetic yellow) work on the display side.

In order to optimize the white line appearing in the image, the embodiment of the invention reduces the brightness of three adjacent illuminating sub-pixels on the display end. Therefore, the video signal end is required to reduce the three RGB grayscale values corresponding to the W sub-pixels, which can be reduced to 200, and the GR grayscale value corresponding to the GR sub-pixels can be reduced to 200.

4(b) shows only four pixels, that is, first to fourth pixels, in which the red sub-pixel and the green sub-pixel in the first pixel emit light and the gray scale values of the red sub-pixel and the green sub-pixel emit light are equal to 255. The blue sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero), and the first pixel presents a yellow color.

The red sub-pixel, the green sub-pixel, and the blue sub-pixel in the fourth pixel are not illuminated (ie, the grayscale value is equal to zero), and the white sub-pixel is illuminated and the grayscale value is equal to 255, and the fourth pixel presents a white color.

In a specific implementation, when a picture transitioning from yellow to white occurs, as shown by the direction of the arrow in FIG. 4(b), the adjacent sub-pixels, that is, the red sub-pixels of the second pixel and the white sub-pixels of the third sub-pixel are simultaneously The light is emitted and the distance between the two is 5 sub-pixels. At this time, a white black line appears in the image.

For example, referring to FIG. 4(c), adjusting the conversion rate of the signal grayscale signal of the W sub-pixel, if the RGB grayscale is equal to 255, the converted RGB sub-pixel grayscale is equal to 55, and the W sub-pixel grayscale is equal to 200. The negative effects of the black line are weakened by the brightness adjustment of the four sub-pixels of WRGB.

FIG. 5(a) shows only four pixels, that is, first to fourth pixels, wherein the green sub-pixel, the red sub-pixel, and the blue sub-pixel in the first pixel are not illuminated (ie, the grayscale value is equal to zero), The white sub-pixel emits light and the grayscale value is equal to 255, at which time the first pixel presents a white color.

The blue sub-pixel and the red sub-pixel in the third pixel emit light, and the grayscale values of the blue sub-pixel and the red sub-pixel emit light are equal to 255, and the green sub-pixel and the white sub-pixel do not emit light (ie, the grayscale value is equal to zero) At this time the third pixel Presents magenta color.
