[ detailed description ] embodiments
The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples of the present application, not all examples, and all other examples obtained by a person of ordinary skill in the art without making any creative effort fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a screen display method according to an embodiment of the present disclosure. As shown in fig. 1, the screen display method may include the steps of:
s11, obtaining gray scale information of a picture to be displayed, wherein the gray scale information comprises gray scale signals of sub-pixels in each pixel.
The frame display method provided by the present embodiment is applied to a display panel, as shown in fig. 2, the display panel includes a plurality of pixels P arranged in an array, and each pixel P includes a plurality of sub-pixels (e.g., a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B). In addition, each step or sub-step included in the image display method provided by this embodiment may be executed by a corresponding image display device, so as to drive the display panel to display the image to be displayed. Specifically, as shown in fig. 3 and 4, the screen display device may be integrated into a display device, the display device may include the display panel and a driving circuit for supplying a driving voltage to the display panel, and, in particular, the screen display device may be integrated into the display panel (as shown in fig. 3) or integrated into the driving circuit (as shown in fig. 4). The display device may be a television, a notebook computer, a tablet computer, a wearable display device (such as an intelligent bracelet, an intelligent watch, and the like), a mobile phone, a virtual reality device, an augmented reality device, a vehicle-mounted display, an advertisement light box, and any product or component with a display function.
Specifically, as shown in fig. 2, the display panel may further include a plurality of scan lines G1 arranged in a row direction ～ Gn, and a plurality of data lines D1 arranged in the column direction ～ Dm, the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B in the display panel may be respectively connected to the corresponding data line and the corresponding scan line. In one example, the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B in the display panel may be divided into a red sub-pixel column, a green sub-pixel column, and a blue sub-pixel column, which are periodically arranged and adjacently arranged in sequence, in a direction from one end of the scan line to the other end, where each of the red sub-pixel column, the green sub-pixel column, or the blue sub-pixel column corresponds to one data line, so that the display device can output a corresponding gray scale signal to the corresponding sub-pixel (for example, the red sub-pixel R, the green sub-pixel G, or the blue sub-pixel B) through the data line by using the driving circuit. It is understood that the gray scale signal of each sub-pixel in the present embodiment may correspond to the gray scale signal outputted to each sub-pixel through the data line, and is used to drive each sub-pixel to emit light, and may specifically be a gray scale voltage.
In this embodiment, the to-be-displayed frame may be a frame of image to be displayed on the display panel, and the gray scale information of the to-be-displayed frame may be obtained by reading a voltage signal of the frame of image from the source driver IC.
In some specific embodiments, the S11 may further specifically include:
s111, when the picture to be displayed is a monochrome picture, obtaining gray scale signals of each sub-pixel in one pixel of the picture to be displayed;
and S112, when the picture to be displayed is not a monochrome picture, acquiring gray scale signals of each sub-pixel in each pixel of the picture to be displayed.
In a specific example, the display color and the display brightness of each pixel of the monochrome picture may be the same. Specifically, the monochrome picture may be a primary color picture (e.g., a red picture, a green picture, or a blue picture) or a single mixed color picture. It is understood that the display colors of the respective pixels of the primary color picture are the same and are primary colors, and the display colors of the respective pixels of the single mixed color picture are the same and are mixed colors which are additively combined by a plurality of primary colors in different proportions.
In a specific implementation, before S111, the screen display method may further include: if it is detected that gray scale signals of each sub-pixel in any two pixels of the picture to be displayed are respectively corresponding to the same gray scale signal, the picture to be displayed can be determined to be a monochrome picture, and otherwise, the picture to be displayed can be determined not to be the monochrome picture. Therefore, when the picture to be displayed is a monochrome picture, only the gray scale signal data of a plurality of sub-pixels included in any pixel of the picture to be displayed needs to be stored, which is beneficial to shortening the flow period and saving the storage space.
And S12, determining a target pixel from the plurality of pixels according to the gray scale signals.
In this embodiment, each pixel may include one target sub-pixel, and the target sub-pixel included in each pixel may correspond to any one of a plurality of sub-pixels included in each pixel. For example, when each pixel includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel, a target sub-pixel included in each pixel may correspond to the red sub-pixel, the green sub-pixel, or the blue sub-pixel included in each pixel.
The target pixel may be a pixel in which a gray scale of a target sub-pixel (e.g., a blue sub-pixel) in the plurality of pixels is a high gray scale, or may be a pixel in which a gray scale of a target sub-pixel in the plurality of pixels is a high gray scale relative to other sub-pixels (e.g., a red sub-pixel and a green sub-pixel). Also, the number of the target pixels may be one or more.
In a specific embodiment, the step S12 may specifically include:
and S121, determining a gray scale value corresponding to each sub-pixel according to the gray scale signal of each sub-pixel.
Specifically, the first lookup table may be established in advance through multiple tests, and the first lookup table may record a one-to-one correspondence relationship between a plurality of gray scale signals (e.g., gray scale voltages) and a plurality of gray scale values. After obtaining the gray scale signal of each sub-pixel, the gray scale value corresponding to the gray scale signal of each sub-pixel can be obtained from the first lookup table.
And S122, determining the ratio of the gray-scale value corresponding to the target sub-pixel in each pixel to the sum of the gray-scale values corresponding to all the sub-pixels in each pixel.
Specifically, when each pixel is composed of a red light sub-pixel, a green light sub-pixel and a blue light sub-pixel, and the target sub-pixel in each pixel is a blue light sub-pixel, a ratio (or called a gray scale ratio) corresponding to the target sub-pixel in each pixel may be equal to gray b/(gray r + gray g + gray b), where gray r, gray g and gray b are a gray scale value corresponding to a red light sub-pixel in each pixel, a gray scale value corresponding to a green light sub-pixel in each pixel and a gray scale value corresponding to a red light sub-pixel in each pixel, respectively.
And S123, determining the pixels, corresponding to the target sub-pixels, of which the ratio is smaller than the preset ratio as the target pixels.
Specifically, when the ratio corresponding to the target sub-pixel in a certain pixel is smaller than the preset ratio, the pixel can be determined to be the target pixel. In one example, the predetermined ratio may be 1/3.
And S13, carrying out visual angle compensation on the gray scale signal of the target sub-pixel in the target pixel to obtain a compensated gray scale signal of the target sub-pixel in the target pixel.
Specifically, after at least one target pixel is determined from the plurality of pixels, the single-color VAC debugging can be started for each target pixel, and the single-color VAC debugging is not started for other pixels except the target pixel, so as to avoid the problem that the display viewing angle of some color-mixed pictures is deteriorated when the single-color VAC debugging is started for the plurality of pixels, for example, the inventor finds that, after the VAC debugging is started for the blue sub-pixels of the plurality of pixels, the viewing angle of some color-mixed pictures is deteriorated when the VAC debugging is not started, or the gray scale of the blue sub-pixels is high, or the gray scale of the blue sub-pixels is relatively high with respect to the gray scale of the red sub-pixels and the gray scale of the green sub-pixels, that is, the difference between the red-green-blue three-primary color ratio of the color-mixed picture observed at a large viewing angle and the red-blue three-primary color ratio of the color-mixed picture observed at an orthographic viewing angle is larger than when the blue VAC debugging is not started, the viewing angle of the mixed color picture is deteriorated, which is not beneficial to improving the improving effect of starting monochromatic VAC debugging on the VA display viewing angle and the moving head pattern.
Moreover, it can be understood that, in this embodiment, by starting the monochrome VAC debugging on the target pixel and not starting the monochrome VAC debugging on other pixels except the target pixel, not only can the improvement effect of the monochrome VAC debugging on the display viewing angle and the wobbling texture of the display panel be achieved, but also the deterioration of the display viewing angle of the specific color-mixed picture (for example, a picture in which the target sub-pixel of starting the VAC is a high gray scale in one pixel or a picture in which other sub-pixels are high gray scales) of the display panel by the monochrome VAC debugging can be eliminated, so that the improvement effect of the monochrome VAC on the display viewing angle and the wobbling texture can be enhanced, which is beneficial to the wide-range popularization of the picture display method in this embodiment.
In this embodiment, starting the monochrome VAC debugging for each target pixel may specifically refer to: and starting VAC debugging on target sub-pixels in each target pixel, and not starting VAC debugging on other sub-pixels except the target sub-pixels in each target pixel. The present application does not limit the specific implementation of the VAC debugging, and in a specific example, the VAC debugging may be implemented by combining two adjacent sub-pixels connected to the same data line and having the same gray scale and the same color of light emission, and adjusting an appropriate H/L value after respectively applying a voltage value (i.e., an H/L value) higher/lower than the original gray scale voltage, so as to achieve substantially unchanged front brightness and reduced front/side brightness curve differences, thereby achieving an improvement in viewing angle.
In a specific embodiment, the S13 may specifically include:
s131, determining a positive compensation gray scale signal and a negative compensation gray scale signal corresponding to the gray scale signal of the target sub-pixel in the target pixel.
Specifically, corresponding H/L values may be set for different gray scale signals of the target sub-pixel, where the positive compensation gray scale signal and the negative compensation gray scale signal may be an H value and an L value, respectively.
S132, according to the positive compensation gray scale signal and the negative compensation gray scale signal, determining a compensated gray scale signal of a target sub-pixel in the corresponding target pixel.
Specifically, the luminance corresponding to the compensated gray scale signal of the target sub-pixel in each target pixel may be equal to the average of the luminance corresponding to the positive compensated gray scale signal corresponding to the target sub-pixel in each target pixel and the luminance corresponding to the negative compensated gray scale signal corresponding to the target sub-pixel in each target pixel.
And S14, driving the display panel to display the picture to be displayed according to the compensated gray scale signal and the gray scale signal.
Specifically, after the compensated gray scale signal of the target sub-pixel in each of the target pixels is determined, the compensated gray scale signal of the target sub-pixel in each of the target pixels may be output to the target sub-pixel in each of the target pixels, the gray scale signals of the target sub-pixels in other pixels may be output to the target sub-pixels in other pixels except the target pixel in the plurality of pixels, and the gray scale signals of the other sub-pixels may be output to the other sub-pixels except the target sub-pixel in the display panel, so as to drive the display panel to display the to-be-displayed image.
As can be seen from the above, the image display method in this embodiment is applied to a display panel, and obtains gray scale information of an image to be displayed, where the gray scale information includes gray scale signals of each sub-pixel in each pixel, and determines a target pixel from a plurality of pixels according to the gray scale signals, then, the gray scale signal of the target sub-pixel in the target pixel is compensated in view angle to obtain the compensated gray scale signal of the target sub-pixel in the target pixel, and the display panel is driven to display the picture to be displayed according to the compensated gray scale signal and the gray scale signal, thereby being capable of selectively carrying out monochrome visual angle compensation on partial pixels of the picture to be displayed and not carrying out monochrome visual angle compensation on other pixels of the picture to be displayed, so as to reduce the negative influence of the starting of the monochromatic visual angle compensation on the display visual angle of the color mixing picture of the display panel, and further improving the effect of starting monochromatic visual angle compensation on the display visual angle and the shaking marks of the display panel.
