Example 1
Referring to fig. 1, fig. 1 is a flow chart of a first embodiment of a method for adjusting a display panel according to the present invention. The invention provides a first embodiment of a method for adjusting a display panel.
In this embodiment, the method for adjusting the display panel includes:
step S10: and acquiring a current crosstalk display image, and determining a region to be adjusted in the current crosstalk display image according to the display state of the current crosstalk display image.
It should be noted that, the display panel is usually disposed in the display device, and the display device usually also has a TCON (Timing Controller, timing control board), and in addition, since the display panel is not a self-luminous device, the display device also needs to be provided with a backlight module below the display panel to provide a basic light source for the display panel, so as to achieve the purpose of displaying images.
It will be appreciated that the current crosstalk display image refers to the currently used crosstalk picture, typically solid color. The crosstalk picture is typically composed of two parts: the same is true for the peripheral frame and the middle frame, and as shown in fig. 2, the current crosstalk display image includes a first display area a and a second display area B, which are respectively used for displaying two partial frames, and the second display area B is located at the periphery of the first display area a.
It should be understood that, the area to be adjusted refers to an area where vertical crosstalk occurs in the current crosstalk display image, and the area where vertical crosstalk occurs typically has a display difference, and vertical crosstalk typically occurs in a middle portion of the picture and a top portion and a bottom portion corresponding to the middle portion. The display state refers to a display condition of a screen, and the display states in this embodiment include two types: the brightness display state and the color temperature display state, namely the brightness display condition and the color temperature display condition, can find the area with display difference by determining the display state of each position in the image, thereby determining the area to be adjusted.
Further, the step S10 includes: and determining the second adjustment area and the third adjustment area in the second display area according to the display state of the second display area by taking the first display area as the first adjustment area, wherein the second adjustment area is positioned above the first adjustment area, and the third adjustment area is positioned below the first adjustment area.
It should be noted that, because the difference between the top and the bottom of the vertical crosstalk is not identical, and the picture of the middle portion is different from the picture of the top and the bottom, the adjustment needs to be performed respectively, and the to-be-adjusted area includes a first adjustment area, a second adjustment area, and a third adjustment area, which correspond to the middle portion, the top, and the bottom, respectively, the first display area is the middle portion, that is, the first adjustment area, and the area where the display difference occurs in the second display area is the second adjustment area and the third adjustment area, which are generally located above and below the first adjustment area, as shown in fig. 3, in this embodiment, the to-be-adjusted area is divided into three portions: the first adjustment area C1, the second adjustment area C2 and the third adjustment area C3 in the present embodiment are the first display area in the middle portion, and the top and bottom areas are the second adjustment area C2 and the third adjustment area C3, respectively.
In a specific implementation, the current crosstalk display image of the TCON recognition panel uses the first adjustment area of the middle part and the top and bottom areas of the first adjustment area as the second adjustment area and the third adjustment area respectively, and the three areas are adjusted respectively later.
Step S20: and acquiring a current display color combination of the current crosstalk display image, and determining a current backlight adjustment strategy corresponding to the current display color combination in a backlight configuration table according to the current display color combination.
It should be noted that the obtaining the current display color combination of the current crosstalk display image includes: and acquiring a first display color of the first display area and a second display color of the second display area, and determining a current display color combination according to the first display color and the second display color. The first display color is the color of the image in the first display area, the second display color is the color of the image in the second display area, and the current display color combination refers to the combination of the image colors in the current first display area and the second display area, that is, the combination corresponding to the first display color and the second display color, for example: the first display color is Gray255, the second display color is Gray0, and the current display color combination is [ Gray255, gray0].
It will be appreciated that the first display color may be a gray scale color, for example: gray255/Gray0 is more commonly used, and the first display color may also be a color, such as: R/G/B/RG/RB/GB wherein R, G and B represent red, green and blue respectively. The second display color may be any one of Gray0 to Gray255, for example: gray0/Gray20/Gray63/Gray127/Gray190/Gray240/G255, with Gray64/Gray127 being more common. The first display color and the second display color need to be determined according to practical situations, which is not limited in this embodiment.
It should be understood that the current backlight adjustment strategy refers to the adjustment currently required to be performed on the backlight illumination module, for example: the method comprises the steps of improving the brightness to 98%, reducing the brightness to 85% and the like, wherein the backlight configuration table refers to a table for storing information related to the adjustment modes of backlight illumination modules, is preset and stored in TCON, the backlight configuration table stores display color combinations and backlight adjustment strategies corresponding to the display color combinations, the display color combinations refer to combinations of colors corresponding to intermediate pictures and external pictures, the backlight adjustment strategies refer to adjustment modes of the backlight illumination modules, different display color combinations correspond to adjustment modes of different backlight illumination modules, and the current corresponding adjustment modes are found by determining the current display color combinations.
It should be noted that, the backlight configuration table in this embodiment includes a gray-scale crosstalk backlight configuration table and a color crosstalk backlight configuration table, which correspond to the case that the first display color is a gray-scale color and a color, respectively.
Step S30: and adjusting the backlight source area corresponding to the area to be adjusted according to the current backlight adjustment strategy so as to reduce the difference of the display states in the area to be adjusted.
It is understood that the backlight area refers to an area in the backlight module, and the backlight area corresponding to the area to be adjusted refers to an area in the backlight module that provides a light source for the area to be adjusted. Since the area to be adjusted is divided into three parts and needs to be adjusted respectively, the backlight area is also divided into three parts, the backlight area includes a first backlight area, a second backlight area and a third backlight area, and the first adjustment area, the second adjustment area and the third adjustment area correspond to the first backlight area, the second backlight area and the third backlight area respectively.
It should be understood that only the luminance display state is usually required when the first display color is a grayscale color, and the color temperature display state is also required when the first display color is a color, on the basis of the luminance display state.
Before the adjustment, the initial brightness state of the whole backlight source area is opened by 90% -95%, so that the darker area in the adjustment process can improve the brightness.
In a specific implementation, as shown in fig. 4, according to the current display color combination, in a preset backlight configuration table, a current corresponding adjustment mode is found, and brightness adjustment or brightness and color temperature adjustment is performed on a first backlight area, a second backlight area and a third backlight area corresponding to the first adjustment area, the second adjustment area and the third adjustment area respectively, so as to adjust the display state of the area to be adjusted, so that not only can display differences among 3 adjustment areas be reduced, but also display differences among the second adjustment area, the third adjustment area and other areas in the second display area can be reduced.
In this embodiment, a current crosstalk display image is obtained, a region to be adjusted is determined in the current crosstalk display image, a current display color combination of the current crosstalk display image is obtained, a current backlight adjustment strategy corresponding to the current display color combination is determined in a backlight configuration table according to the current display color combination, the backlight configuration table stores the display color combination and the backlight adjustment strategy corresponding to the display color combination, and according to the current backlight adjustment strategy, a backlight source region corresponding to the region to be adjusted is adjusted, so that a difference of display states in the region to be adjusted is reduced. Since vertical crosstalk generally exists during display and there is a difference between upper and lower crosstalk, the embodiment sets a backlight configuration table, determines a corresponding adjustment mode according to different color combinations of crosstalk images, and adjusts brightness/brightness and color temperature of a backlight partition corresponding to an abnormal display area, so as to improve display difference in a display panel and display effect.
Example two
Referring to fig. 5, fig. 5 is a flowchart illustrating a second embodiment of a method for adjusting a display panel according to the present invention. Based on the first embodiment, the present invention proposes a second example of the adjustment method of the display panel.
In this embodiment, the step S20 includes:
step S201: and when the first display color is a first preset gray scale display color and the second display color is a second preset gray scale display color, determining that the current display color combination is a preset gray scale display combination.
It should be noted that, the preset Gray-scale display combination refers to a preset Gray-scale color combination, at this time, the first display color and the second display color are all Gray-scale colors, the first preset Gray-scale display color refers to all possible Gray-scale colors of the preset first display color, at least includes Gray255 and Gray0, and the second preset Gray-scale display color refers to all possible Gray-scale colors of the preset second display color, including all Gray0 to Gray 255.
In a specific implementation, when the first display color and the second display color are both grayscale colors, the current display color combination is considered to be a grayscale color combination.
Step S202: and when the current display color combination is the preset gray scale display combination, determining the current backlight adjustment strategy in the gray scale crosstalk backlight configuration table according to the current display color combination.
It will be appreciated that the current display color combination is a gray scale color combination, and the corresponding gray scale crosstalk backlight configuration table is used to determine the current adjustment mode.
Further, the step S30 includes:
step S301: and adjusting the brightness display state of the first backlight source area according to a first gray scale crosstalk backlight adjustment strategy.
Step S302: and adjusting the brightness display state of the second backlight source area according to a second gray scale crosstalk backlight adjustment strategy.
Step S303: and adjusting the brightness display state of the third backlight source area according to a third gray scale crosstalk backlight adjustment strategy.
It should be understood that when the current display color combination is a gray-scale color combination, only the brightness display state is considered to be concerned at this time, and therefore, in this embodiment, the backlight adjustment policy stored in the gray-scale crosstalk backlight configuration table is an adjustment manner related to the brightness display state.
It should be noted that, in this embodiment, the three adjustment areas have different adjustment manners, and the current backlight adjustment policy includes a first gray-scale crosstalk backlight adjustment policy, a second gray-scale crosstalk backlight adjustment policy, and a third gray-scale crosstalk backlight adjustment policy, which correspond to adjustment manners of brightness display states in the first backlight area, the second backlight area, and the third backlight area, respectively.
In a specific implementation, the brightness display states in the first backlight area, the second backlight area and the third backlight area are adjusted by using a first gray scale crosstalk backlight adjustment strategy, a second gray scale crosstalk backlight adjustment strategy and a third gray scale crosstalk backlight adjustment strategy respectively.
Further, in order to obtain the gray-scale crosstalk backlight configuration table, before step S10, the method further includes:
and determining a gray scale crosstalk test display image according to the preset gray scale display combination, and determining a gray scale test area according to the brightness display state of the gray scale crosstalk test display image.
