Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
As shown in Figure 1, the application method for displaying image first embodiment includes：
S102：Judge whether the sub-pixel that the picture signal of input is controlled is located at abnormity display platen edge；
Wherein, the picture signal of the input is the grayscale Value Data for controlling sub-pixel for emitting light.Special-shaped display screen refers to
Shape is non-traditional rectangular display screen, such as round, triangle or non-regular shape display screen.
Specifically, in an application examples, after special-shaped display screen receives the picture signal of input, judge the figure of the input
Whether the sub-pixel controlled as signal is located at abnormity when showing platen edge, can obtain what the picture signal of the input was controlled
The location information of sub-pixel is compared then by the location information and preset position information, if the location information and default position
Information matches are set, then can be determined that the sub-pixel that the picture signal of the input is controlled is located at abnormity display platen edge.Wherein, should
The location information of sub-pixel can be position coordinates (such as line information), can also be the sub-pixel and some default sub-pixel
The range information of (such as first sub-pixel of first trip), the preset position information can be according to size, the shapes etc. of special-shaped display screen
Material elements are configured, and are not specifically limited herein.
For example, the location information for the sub-pixel that the picture signal of the input is controlled can be that sub-pixel distance abnormity is aobvious
The distance of display screen center-subpixels, the preset position information can be pre-determined distance ranges, if sub-pixel distance abnormity is shown
Shield the distance of center-subpixels within the scope of the pre-determined distance, then can be determined that the sub-pixel is located at abnormity and shows platen edge.Its
In, which can be the edge subpixel of the row/column where the sub-pixel at a distance from center-subpixels.
Certainly, in other application example, can also pre-recorded all edge subpixels position coordinates, then judge defeated
The position coordinates for the sub-pixel that the picture signal entered is controlled whether in pre-recorded edge subpixel position coordinates, to
It may determine that whether the sub-pixel that the picture signal of input is controlled is located at abnormity display platen edge.
S104：If the determination result is YES, then the picture signal is handled, to reduce the grayscale value of sub-pixel；
It specifically, can be with when judging that the sub-pixel that is controlled of picture signal of the input is located at abnormity and shows platen edge
Picture signal is handled, to reduce the grayscale value of the sub-pixel.Specific image-signal processing method can directly will
Some less preset value of grayscale value of sub-pixel reduces some preset ratio, can also be that picture signal progress is more complicated
Processing, such as be filtered with smoothing processing using a filter etc., specifically can be depending on actual demand, herein not
It is specifically limited.Wherein, the grayscale value of the sub-pixel represented by picture signal that treated can be the grayscale value before processing
0.5~0.7.Certainly, the decrement of the grayscale value of the sub-pixel can also be depending on actual displayed demand.
Optionally, as shown in Fig. 2, step S104 includes：
S1041：Picture signal is filtered using low-pass filter, to filter out the high fdrequency component in the picture signal,
So that the grayscale value of sub-pixel is reduced.
Wherein, which is N rank low-pass filters, it is contemplated that the influence of adjacent subpixels, the N take more than 2
Odd number usually takes 3.The type of the low-pass filter can be selected according to actual demand, the cutoff frequency of different types of filter
Rate is different, such as the cutoff frequency of gauss low frequency filter can be 80Hz.
In general, when the display grayscale value of sub-pixel is bigger, the picture signal high frequency components for controlling the sub-pixel are more,
It, can be low by one by the picture signal for controlling the sub-pixel when therefore, it is necessary to reduce the grayscale value of controlled sub-pixel
Bandpass filter, the high order component that frequency is more than to the low pass filter cutoff frequency filter out, so that picture signal is flat
It is sliding, and the grayscale value of the sub-pixel is reduced.
Certainly, in other embodiments, filter can not also be used, directly by the grayscale value represented by the picture signal
It reduces, such as is directly reduced to the half of former grayscale value.
S106：Output treated picture signal, with the image after display processing.
Specifically, in the above application examples, after handling the picture signal, the grayscale value represented by the picture signal
Reduce, then output should after treated picture signal, should treated picture signal control sub-pixel for emitting light when, the sub-pixel
Brightness reduce, with the luminance differences of other adjacent color sub-pixels away from smaller, at this point it is possible to be the equal of borrowed it is adjacent
Other color sub-pixels are shown, thus be not easy to occur edge individually one or two color sub-pixel the case where, to
Display treated image can be made to eliminate colour edging, display effect is obviously improved.
Such as abnormity shown in Fig. 3 shows platen edge, which uses masonry pixel arrangements, in Fig. 3
One row sub-pixel is red (R) and blue (B) sub-pixel intervals arrangement, and an adjacent row sub-pixel is entirely green (G) sub- picture
Element, the mode that this two row is intervally arranged, then edge is substantially based on red and blue subpixels, shortage green sub-pixels, therefore
It is easy to form purple edge.After the method using the present embodiment reduces the grayscale value of the red at edge and blue subpixels,
The grayscale value of adjacent green sub-pixels can be significantly greater than the red and blue subpixels, can be the equal of having borrowed phase at this time
Adjacent green sub-pixels are shown, it is possible thereby to so that edge forms the complete pixel of red, blue and green three colors,
So as to eliminate colour edging, display effect is improved.
