Another embodiment of the present invention provides a kind of method for displaying image, in the present embodiment for horizontal direction as first direction, is described the method for displaying image in the embodiment of the present invention, and as shown in Figure 3, this method for displaying image comprises:

S201, image display device receive pending image.

Wherein, image display device can receive the pending image from the electronic equipment be connected with the display at image display device place, and electronic equipment sends pending image to display, is used to indicate this display process and shows this pending image.

S202, image display device determine the resolution of pending image.

Be understandable that, for the pending image that resolution is different, image display device may need to adopt different display resolutions (being less than or equal to the physical resolution of display) to show it, therefore, to process and before showing this pending image, image display device needs the resolution determining pending image.

Concrete, when the resolution of pending image is greater than the physical resolution of display, if when then representing that image display device adopts the method for prior art to show this pending image, need the pixel reducing this pending image, the sharpness of the picture that the display screen that then can affect display presents, therefore, the method for the embodiment of the present invention can be adopted to process pending image, namely perform S203.When the resolution of pending image is less than or equal to the physical resolution of display, can with reference to method for displaying image of the prior art, the embodiment of the present invention repeats no more here.

S203, image display device determine the number of pending image pixel in the horizontal direction.

Wherein, if the resolution of image to be displayed is A × B, then A represents the number of image to be displayed pixel in the horizontal direction, and B represents the number of image to be displayed pixel in the vertical direction.Such as, when the resolution of image to be displayed is 3840 × 1080, the number of image to be displayed pixel is in the horizontal direction 3840, and the number of image to be displayed pixel is in the vertical direction 1080.

The size of the number of the more pending image of S204, image display device pixel in the horizontal direction and the physical resolution parameter value in the horizontal direction of display.

Wherein, the physical resolution of display is C × D, then C represents the physical resolution parameter value in the horizontal direction of display, and D represents the physical resolution parameter value in the vertical direction of display.Such as, when the physical resolution of display is 1920 × 1080, the physical resolution parameter value in the horizontal direction of display is 1920, and the physical resolution parameter value in the vertical direction of display is 1080.The size of the number of the more pending image of image display device pixel in the horizontal direction and the physical resolution parameter value in the horizontal direction of display, namely compares the size of A and C.

Concrete, if the number of pending image pixel in the horizontal direction equals 2 times of the physical resolution parameter value in the horizontal direction of display, then perform S205; If the number of pending image pixel is in the horizontal direction greater than the physical resolution parameter value in the horizontal direction of display, and the number of pending image pixel is in the horizontal direction less than 2 times of the physical resolution parameter value in the horizontal direction of display, then perform S206; If the number of pending image pixel is in the horizontal direction greater than 2 times of the physical resolution parameter value in the horizontal direction of display, and the number of pending image pixel is in the horizontal direction less than 3 times of the physical resolution parameter value in the horizontal direction of display, then perform S207.

S206, image display device are that pending image increases pixel, to generate image to be displayed in the horizontal direction.

When the number of pending image pixel is in the horizontal direction greater than the physical resolution parameter value in the horizontal direction of display, and the number of pending image pixel is in the horizontal direction when being less than 2 times of the physical resolution parameter value in the horizontal direction of display, image display device is that pending image increases pixel in the horizontal direction, and the physical resolution image after increase pixel can being met equal display in the number of the pixel of first direction is at 2 times of parameter value of first direction.The method of concrete increase pixel can with reference to correlation technique of the prior art, and the embodiment of the present invention repeats no more here.

S207, image display device reduce the pixel of pending image in the horizontal direction, to generate image to be displayed.

When the number of pending image pixel is in the horizontal direction greater than 2 times of the physical resolution parameter value in the horizontal direction of display, and the number of pending image pixel is in the horizontal direction when being less than 3 times of the physical resolution parameter value in the horizontal direction of display, image display device reduces the pixel of pending image in the horizontal direction, and the physical resolution image after minimizing pixel can being met equal display in the number of the pixel of first direction is at 2 times of parameter value of first direction.The method of concrete minimizing pixel can with reference to correlation technique of the prior art, and the embodiment of the present invention repeats no more here.

Wherein, the number of pending image pixel in the horizontal direction generally can not be greater than 3 times of the physical resolution parameter value in the horizontal direction of display.If the number of pending image pixel is in the horizontal direction greater than 3 times of the physical resolution parameter value in the horizontal direction of display, image display device also can reduce the pixel of pending image in the horizontal direction, physical resolution image after minimizing pixel can being met equal display in the number of the pixel of first direction is at 2 times of parameter value of first direction, but the pixel decreasing pending image that like this may be too much, the sharpness of the picture that the display screen affecting display presents.Now, can with reference to the method for the embodiment of the present invention, physical resolution image after minimizing pixel can being met equal display in the number of the pixel of first direction is at 3 times of parameter value of first direction, and increase by the 4th pixel, 4th pixel is adjacent with the 3rd pixel, in the first subframe, display N number of viewing area in the horizontal direction show by the first pixel, the first grey decision-making that second pixel and the 3rd pixel calculate, in the second subframe, display N number of viewing area in the horizontal direction show by the second pixel, the second grey decision-making that 3rd pixel and the 4th pixel calculate.

Exemplary, as shown in Figure 4, the embodiment of the present invention is with the resolution of image to be displayed for 3840 × 1080, and the physical resolution of display is 1920 × 1080 to be described for example.The number of image to be displayed pixel is in the horizontal direction 3840, and the physical resolution parameter value in the horizontal direction of display is 1920, and namely display has 1920 viewing areas in the horizontal direction.
