Driving method for liquid crystal display brightness dynamic blurring and liquid crystal display

The present invention claims the prior application priority of the invention titled "A Driving Method for Dynamic Blur of Brightness of Liquid Crystal Display and Liquid Crystal Display", which is filed on April 21, 2017, the content of which is hereby incorporated by reference. The manner of introduction is incorporated into this text.

Technical field

The invention belongs to the field of display technology, and in particular to a driving method for liquid crystal display brightness blurring and a liquid crystal display.

Background technique

With the development of LCD (Liquid Crystal Display), not only the demand for LCD panel size is increasing, the resolution of display is getting higher and higher, and the definition of LCD panel is getting higher and higher. LCD picture quality requirements are also getting higher and higher, and the power consumption requirements for backlights are getting lower and lower. In order to satisfy people's pursuit of high quality and low power consumption, how to reduce the power consumption of backlights is the most concerned. Because the backlight is the largest energy consumer, the power consumption of the backlight is reduced, which greatly reduces the power consumption of the whole machine. At present, the CABC (Content Adaptive Brightness Control) function added to the liquid crystal panel driver chip can effectively reduce the backlight power consumption.

The CABC function added to the existing liquid crystal panel driver chip to reduce the power consumption of the backlight is used to prevent the sudden change of brightness from being unsuitable to the human eye, and the Dimming function is used to adjust the backlight PWM within a certain period of time ( The plus-width modulation signal is finally used to achieve a gradual uniform change in backlight brightness to the desired brightness value. As shown in FIG. 1 , there is no Diming function and a brightness change with Diming function in the prior art, and the brightness change with the Diming function is generally set, and then the multi-step backlight switching control is adopted. This method can improve the brightness change to the human eye without the Diming function. The incompatibility brought about, but the power consumption is wasted under the picture that some brightness does not need multi-level switching.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terms "including" and "having" appear in the specification, claims, and drawings of the application and Any deformation of them is intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or alternatively Other steps or units inherent to these processes, methods, products or equipment. Moreover, the terms "first," "second," and "third," etc. are used to distinguish different objects, and are not intended to describe a particular order.

Embodiments of the present invention provide a driving method for dynamically blurring a brightness of a liquid crystal display. The liquid crystal display panel includes a display area and a non-display area, and the display area of the liquid crystal display includes an adjustment area. In one case, the adjustment area The area of the display area is smaller than the area of the display area (in this embodiment), that is, the adjustment area is a small area in the display area, and in another case, the adjustment area may also be the entire display area. That is, the area of the adjustment area is equal to the area of the display area. The adjustment area includes at least one pixel, for example, including one pixel, two pixels, three pixels, six pixels, ten pixels, twenty pixels, and the like. In this embodiment, the adjustment area includes a plurality of pixels. Each pixel includes a red sub-pixel (R), a green sub-pixel (G), and a blue sub-pixel (B). In this embodiment, referring to FIG. 2 and FIG. 3, the driving method includes:

S110: Obtain the next frame picture information that the adjustment area is about to switch to;

In this embodiment, the liquid crystal display obtains the next frame picture information to be switched to the adjustment area. Specifically, the liquid crystal display obtains the brightness information of the next frame picture of all pixels in the adjustment area, where The brightness information refers to the brightness information adjusted by the CABC function, for example, the gray level of the red sub-pixel in a certain pixel, the gray level of the green sub-pixel, and the gray level of the blue sub-pixel.

S120: Analyze the dominant situation of the red sub-pixel, the green sub-pixel, and the blue sub-pixel in the next frame picture information;

In this embodiment, according to the obtained next frame picture information, the liquid crystal display analyzes the dominant situation of the red sub-pixel, the green sub-pixel, and the blue sub-pixel in the next frame picture information. In this embodiment, which one is pointed out The sub-pixel predominance refers to the highest gray level of the sub-pixel in the pixel where the sub-pixel is located. For example, in a certain pixel, the gray sub-pixel has a gray scale of 100, the green sub-pixel has a gray scale of 200, and the blue sub-pixel. The gray level is 50, in which case the green sub-pixel dominates the pixel. Of course, in this embodiment, when the gray levels of the two sub-pixels are the same in one pixel, the gray levels of the two sub-pixels (one of the sub-pixels are green sub-pixels) are greater than the gray level of the third sub-pixel, such In this case, the embodiment provides that the green sub-pixel is dominant in the pixel, and the design is to improve the brightness. The change brings to the human eye the inconvenience, of course, in order to save energy, in other embodiments of the invention, non-green sub-pixels may also be defined as dominant. In addition, in other embodiments of the present invention, which sub-pixel is dominant in one pixel may also be in other known manners, for example, by a luminance domain, but the manner of calculating the relative grayscale is complicated. It is also possible to obtain which color dominates the next frame in the adjustment area.

S130: determining whether a proportion of the dominant condition of the green sub-pixel is greater than or equal to a sum of a proportion of a dominant condition of the red sub-pixel and the blue sub-pixel;

In this embodiment, since the human eye is relatively sensitive to green brightness and relatively low in sensitivity to red brightness and blue brightness, after analyzing in step S120, the liquid crystal display determines that the green sub-pixel is dominant according to the analysis result. Whether the proportion of the situation is greater than the sum of the proportions of the red sub-pixel and the blue sub-pixel, for example, in the next frame information of the adjustment area, the proportion of the green sub-pixel dominates is 60%, and the red sub-pixel The proportion of dominant cases is 15%, and the proportion of blue sub-pixels is 25%. At this time, the liquid crystal display judges that the proportion of green sub-pixels is 60% larger than that of red sub-pixels and blue sub-pixels. The proportion of the dominant situation is 40%.

S141: If yes, the backlight brightness is adjusted to the target brightness by the first brightness order to perform the next frame display;

In this embodiment, if the ratio of the dominant condition of the green sub-pixel is greater than or equal to the sum of the proportions of the red sub-pixel and the blue sub-pixel, at this time, the next frame of the adjustment area When displayed, the color is relatively green. Because the human eye is sensitive to green brightness, when switching from the current frame to the next frame, if the brightness changes greatly per unit time, this change will bring no eye to the human eye. Adapting, in order to reduce the incompatibility, the brightness of the backlight is adjusted to the target brightness by the first brightness order, where the first brightness order means that the brightness is changed from the current picture to the target picture, and the first brightness order is changed. For example, the number of the first brightness orders is 4-8, for example, 4, 5, 6, 7, and 8. In this embodiment, the number of brightnesses of the first brightness order is 6, please refer to FIG. The figure shown on the side. Here, since the number of first brightness orders is large, and the current brightness is switched to the target brightness by 6 times, the amplitude of each brightness change is not large, even if the human eye is sensitive to green, each time change It will not bring discomfort to the human eye.

S142: If not, the backlight brightness is adjusted to the brightness of the eye by the second brightness order to perform the next frame display, wherein the first brightness order is greater than the second brightness order.

In this embodiment, if the ratio of the dominant condition of the green sub-pixel is smaller than the sum of the proportions of the red sub-pixel and the blue sub-pixel, at this time, when the next frame of the adjustment area is displayed The color is more red or blue. Since the human eye is not sensitive to red or blue brightness, when switching from the current frame to the next frame, even if the brightness changes greatly per unit time, the change will not In order to reduce the switching frequency of the backlight brightness to reduce the power consumption, thereby saving energy, in the embodiment, the backlight brightness is adjusted to the target brightness by the second brightness order to perform A frame display, where the second brightness order means that the brightness is changed from the current picture to the target picture, and the second brightness order is changed. For example, the number of second brightness orders is 1-5, for example, 1, 2 3, 4, 5, in this embodiment, the number of brightness of the second brightness order is 3, please refer to the figure shown on the left side of FIG. Here, since the second brightness order is smaller than the first brightness order, the current brightness is switched to the target brightness three times, and the amplitude of each brightness change is larger than the first brightness order, thereby reducing The switching frequency of the backlight brightness reduces power consumption.

In this embodiment, when the ratio of the dominant condition of the green sub-pixel in which the next frame is sensitive to the human eye is greater than or equal to the sum of the proportions of the red sub-pixel and the blue sub-pixel, the brightness change is reduced. The human eye brings incompatibility, and the brightness of the backlight is adjusted to the target brightness by the first brightness order greater than the second brightness order. At this time, the amplitude of each brightness change is not large, so that the brightness change does not bring the eye to the human eye. Adaptation; when the ratio of the proportion of the red sub-pixel and the blue sub-pixel that are less sensitive to the human eye in the next frame is greater than the proportion of the dominant sub-pixel in the green frame, even if the brightness changes greatly, It will bring discomfort to the human eye. The brightness of the backlight is adjusted to the target brightness with a second brightness order smaller than the first brightness order, which can reduce the switching frequency of the backlight brightness, thereby reducing power consumption, thereby contributing to energy saving.

In this embodiment, step S120 specifically includes:

S121: Compare grayscale sizes of red sub-pixels, green sub-pixels, and blue sub-pixels in each pixel in the next frame picture information;

In this embodiment, the adjustment area includes a plurality of pixels, and based on obtaining the next frame picture information, the display panel can obtain the red sub-pixel, the green sub-pixel, and the blue sub-pixel in each pixel in the next frame picture. Gray scale size, for example, in one of the pixels, the gray level of the red sub-pixel is 100, the gray level of the green sub-pixel is 200, and the gray level of the blue sub-pixel is 50, and the gray scale of each sub-pixel in the pixel is compared. In this example, the gray level of the green sub-pixel 200> the gray level of the red sub-pixel 100> blue Grayscale 50 of the sub-pixel.

S122: Count the maximum number of pixels of the gray color of the green sub-pixel, the maximum number of pixels of the gray sub-pixel gray scale, and the maximum number of pixels of the gray color of the blue sub-pixel.

In this embodiment, the gray level is maximum for which sub-pixel of one pixel has the largest gray scale. In the above example, the gray scale 200 of the green sub-pixel is the largest among the pixels. Counting the number of pixels with the largest gray scale of each sub-pixel in the adjustment area, for example, the number of pixels in the adjustment area is 20, the number of pixels having the largest gray scale of the green sub-pixel is 12, and the number of pixels having the largest gray scale of the red sub-pixel For six, the maximum number of pixels in the gray level of the blue sub-pixel is two. Here, when the gray scale of the green sub-pixel in one pixel is the same as the gray scale of the other two sub-pixels, and both are larger than the gray scale of the remaining sub-pixels, in order to reduce the inconvenience of the human eye, the design is The gray level of the green sub-pixel in the pixel is the largest in the pixel.

In this embodiment, step S122 specifically includes:

In this embodiment, based on the obtained gray scale size of the red sub-pixel, the green sub-pixel, and the blue sub-pixel in each pixel, the liquid crystal display determines whether the gray scale of the green sub-pixel in the same pixel is greater than or equal to the red sub-pixel. The gray scale is greater than or equal to the gray scale of the blue sub-pixel. In the above example, the gray scale 200 of the green sub-pixel > the gray scale 100 of the red sub-pixel > the gray scale 50 of the blue sub-pixel.

In this embodiment, assuming that the liquid crystal display counts the previous pixel, the maximum number of pixels of the green sub-pixel gray scale is a, the maximum number of pixels of the red sub-pixel gray scale is b, and the number of pixels of the blue sub-pixel gray scale is the largest. For c, the gray level of the green sub-pixel in the current pixel is greater than or equal to the gray level of the red sub-pixel and greater than or equal to the gray level of the blue sub-pixel, and the maximum number of pixels of the gray color of the green sub-pixel is increased by 1, that is, A+1, the maximum number of pixels of the gray sub-pixel gray scale and the maximum number of pixels of the blue sub-pixel gray scale are unchanged.

In this embodiment, it is assumed that when the previous pixel is counted, the maximum number of pixels of the green sub-pixel gray scale is a, the maximum number of pixels of the red sub-pixel gray scale is b, and the number of pixels of the blue sub-pixel gray scale is the largest. The target is c. When the gray level of the red sub-pixel in the current pixel is maximum, the maximum number of pixels of the gray sub-pixel gray scale is increased by 1, that is, b+1, the maximum number of pixels of the gray color of the green sub-pixel and the blue color. The maximum number of pixels of the sub-pixel gray scale is unchanged; when the gray scale of the blue sub-pixel in the current pixel is maximum, the maximum number of pixels of the gray sub-pixel gray scale is increased by 1, that is, c+1, the green sub-pixel The maximum number of pixels in the grayscale and the maximum number of pixels in the grayscale of the red subpixel are unchanged.

In this way, the number of pixels with the largest gray scale of the green sub-pixel, the number of pixels with the largest gray sub-pixel gray scale, and the maximum number of pixels with the gray sub-pixel gray scale can be obtained when the next frame of the adjustment region is obtained. Assume that the number of pixels with the largest gray scale of the green sub-pixel after the statistics is A, the number of pixels with the largest gray scale of the red sub-pixel is B, and the number of pixels with the largest gray scale of the blue sub-pixel is C, then the proportion of the green sub-pixel dominates. For A/(A+B+C), the proportion of red subpixels dominates is B/(A+B+C), then the proportion of blue subpixels dominates is C/(A+B). +C), the sum of the dominant cases of the red sub-pixel and the blue sub-pixel is (B+C)/(A+B+C).

In addition, in the embodiment, in order to reduce the inaccuracy of the brightness change caused by the change of the brightness and reduce the switching frequency of the backlight brightness to reduce the power consumption, the sizes of the steps in the first brightness order are the same, that is, 6 The first brightness change in the unit time in the step is the same, and the size of each step in the second brightness order is the same, that is, the second brightness change in the unit time in the three steps is the same, and, in this embodiment, The first brightness change is less than the second brightness change.
