圖2A至圖2E為依據本發明的一實施例的影像的位移方式的示意圖。請參照圖1及圖2A至圖2E，在本實施例中，自發光顯示面板10係包括影像顯示區域RID及週邊區域RPE，其中影像顯示區域RID及週邊區域RPE分別配置有多個畫素(如PPX1~PPX3)，並且影像顯示區域RID用以顯示畫面影像IMF，亦即畫面影像IMF的大小實質上可以等於影像顯示區域RID的大小。各個畫素(如PPX1~PPX3)為自發光畫素且分別包括多個子畫素(如紅色子畫素R1~R3、綠色子畫素G1~G3、以及藍色子畫素B1~B3)，並且影像顯示區域RID中的畫素(如PPX1)及週邊區域RPE的畫素(如PPX2~PPX3)具有相同結構。 2A to 2E are schematic diagrams of an image displacement method according to an embodiment of the invention. 1 and 2A to 2E, in this embodiment, the self-luminous display panel 10 includes an image display area RID and a peripheral area RPE, wherein the image display area RID and the peripheral area RPE are respectively configured with a plurality of pixels ( Such as PPX1~PPX3), and the image display area RID is used to display the screen image IMF, that is, the size of the screen image IMF can be substantially equal to the size of the image display area RID. Each pixel (such as PPX1~PPX3) is a self-luminous pixel and includes multiple sub-pixels (such as red sub-pixels R1~R3, green sub-pixels G1~G3, and blue sub-pixels B1~B3), And the pixels in the image display area RID (such as PPX1) and the pixels in the surrounding area RPE (such as PPX2~PPX3) have the same structure.

在本實施例中，繪示單一個畫素(亦左上角的顯示畫素) 的位移以便於說明，但實際上可以是整個畫面影像IMF在移動。在此，假設畫面影像IMF的位移路徑是自右至左移動。如圖2A所示，當位移電路120未位移畫面影像IMF時，畫面影像IMF的左上角顯示畫素之顯示區域等同於畫素PPX1的紅色子畫素R1、綠色子畫素G1及藍色子畫素B1。 In this embodiment, a single pixel is shown (also the display pixel in the upper left corner) The displacement of is convenient for illustration, but in fact it can be that the entire screen image IMF is moving. Here, it is assumed that the displacement path of the screen image IMF is moving from right to left. As shown in FIG. 2A, when the shift circuit 120 does not shift the screen image IMF, the display area of the display pixel in the upper left corner of the screen image IMF is equivalent to the red sub-pixel R1, green sub-pixel G1, and blue sub-pixel of the pixel PPX1. Pixel B1.

如圖2B所示，當位移電路120對畫面影像IMF往左位移一個子畫素時，畫面影像IMF的經位移顯示畫素DPX1之顯示區域橫跨畫素PPX1(亦即原畫素區域)的紅色子畫素R1及綠色子畫素G1及畫素PPX2(亦即新畫素區域)的藍色子畫素B2，亦即畫面影像IMF之經位移顯示畫素DPX1之顯示區域橫跨畫素PPX1及PPX2之所在區域。 As shown in FIG. 2B, when the shift circuit 120 shifts the screen image IMF by one sub-pixel to the left, the display area of the shifted display pixel DPX1 of the screen image IMF crosses the display area of the pixel PPX1 (that is, the original pixel area) The red sub-pixel R1 and the green sub-pixel G1 and the blue sub-pixel B2 of the pixel PPX2 (that is, the new pixel area), that is, the display area of the shifted display pixel DPX1 of the screen image IMF spans the pixel The area where PPX1 and PPX2 are located.

當經位移顯示畫素DPX1橫跨不同畫素PPX1及PPX2之所在區域時，補償電路140於安排新畫素PPX2區域內影像顯示區域RID外之紅色子畫素R2及綠色子畫素G2作為補償子畫素，並且點亮作為補償子畫素的紅色子畫素R2及綠色子畫素G2。換言之，上述補償子畫素，與經位移的顯示畫素DPX1於原畫素PPX1重疊的區域內之紅色子畫素R1及綠色子畫素G1，具有相同之顏色。並且，在本發明實施例中，補償子畫素(例如紅色子畫素R2及綠色子畫素G2)，與經位移的顯示畫素DPX1於原畫素PPX1的區域內之紅色子畫素R1及綠色子畫素G1之亮度，相較係較暗，例如為0.25~0.5倍亮度。藉此，透過點亮補償子畫素，可用於降低畫面影像IMF經位移所造成於影像畫面IMG之邊緣的視覺不平 滑效應。換言之，不同的兩畫素之所在區域PPX1及PPX2可以包括一原畫素區域與一新畫素區域。補償電路係於安排該新畫素區域內該影像顯示區域外之至少一子畫素作為該至少一補償子畫素。 When the shifted display pixel DPX1 straddles the area where the different pixels PPX1 and PPX2 are located, the compensation circuit 140 arranges the red sub-pixel R2 and the green sub-pixel G2 outside the image display area RID in the new pixel PPX2 area as compensation Sub-pixels, and light up the red sub-pixel R2 and the green sub-pixel G2 as compensation sub-pixels. In other words, the compensation sub-pixel, the red sub-pixel R1 and the green sub-pixel G1 in the area where the shifted display pixel DPX1 overlaps the original pixel PPX1, have the same color. Moreover, in the embodiment of the present invention, the compensation sub-pixels (for example, the red sub-pixel R2 and the green sub-pixel G2) are compared with the red sub-pixel R1 of the shifted display pixel DPX1 in the area of the original pixel PPX1 And the brightness of the green sub-pixel G1 is darker than that of, for example, 0.25 to 0.5 times the brightness. In this way, by lighting the compensation sub-pixels, it can be used to reduce the visual unevenness at the edges of the image screen IMG caused by the displacement of the screen image IMF Slippery effect. In other words, the areas PPX1 and PPX2 where the two different pixels are located can include an original pixel area and a new pixel area. The compensation circuit arranges at least one sub-pixel outside the image display area in the new pixel area as the at least one compensation sub-pixel.

如圖2C所示，當位移電路120對畫面影像IMF再往左位移一個子畫素時，畫面影像IMF的經位移顯示畫素之顯示區域等同於畫素PPX2的紅色子畫素R2、綠色子畫素G2及藍色子畫素B2，亦即畫面影像IMF之經位移畫素之顯示區域橫跨單一畫素PPX2之所在區域。當畫面影像IMF之經位移畫素之顯示區域橫跨單一畫素PPX2之所在區域時，補償電路140可以不產生補償子畫素。 As shown in FIG. 2C, when the shift circuit 120 shifts the screen image IMF by one sub-pixel to the left, the display area of the shifted display pixel of the screen image IMF is equivalent to the red sub-pixel R2 and the green sub-pixel of the pixel PPX2. The pixel G2 and the blue sub-pixel B2, that is, the shifted pixel display area of the screen image IMF spans the area where the single pixel PPX2 is located. When the display area of the shifted pixel of the screen image IMF spans the area where the single pixel PPX2 is located, the compensation circuit 140 may not generate compensation sub-pixels.

如圖2D所示，當位移電路120對畫面影像IMF再往左位移一個子畫素時，畫面影像IMF的經位移顯示畫素DPX2之顯示區域橫跨畫素PPX2的紅色子畫素R2及綠色子畫素G2及畫素PPX3的藍色子畫素B3，亦即畫面影像IMF之經位移顯示畫素DPX2之顯示區域橫跨畫素PPX2及PPX3之所在區域。此時，補償電路140於安排新畫素PPX3之紅色子畫素R3及綠色子畫素G3當中至少之一者作為補償子畫素，並且點亮作為補償子畫素的紅色子畫素R3及綠色子畫素G3當中至少之一者，其亮度可較紅色子畫素R2與綠色子畫素G2的亮度為暗，譬如是0.25~0.5倍紅色子畫素R2與綠色子畫素G2的亮度。 As shown in FIG. 2D, when the shift circuit 120 shifts the screen image IMF by one sub-pixel to the left, the display area of the shifted display pixel DPX2 of the screen image IMF spans across the red sub-pixel R2 and green of the pixel PPX2 The sub-pixel G2 and the blue sub-pixel B3 of the pixel PPX3, that is, the display area of the shifted display pixel DPX2 of the screen image IMF spans the area where the pixels PPX2 and PPX3 are located. At this time, the compensation circuit 140 arranges at least one of the red sub-pixel R3 and the green sub-pixel G3 of the new pixel PPX3 as the compensation sub-pixel, and lights up the red sub-pixel R3 and the red sub-pixel as the compensation sub-pixel. The brightness of at least one of the green sub-pixel G3 may be darker than the brightness of the red sub-pixel R2 and the green sub-pixel G2, for example, 0.25 to 0.5 times the brightness of the red sub-pixel R2 and the green sub-pixel G2 .

如圖2E所示，當位移電路120對畫面影像IMF再往左位 移一個子畫素時，畫面影像IMF的經位移顯示畫素之顯示區域等同於畫素PPX3的紅色子畫素R3、綠色子畫素G3及藍色子畫素B2，亦即畫面影像IMF之經位移畫素之顯示區域橫跨單一畫素PPX3之所在區域。此時，補償電路140係可不產生補償子畫素。 As shown in FIG. 2E, when the shift circuit 120 adjusts the IMF of the screen image to the left When one sub-pixel is moved, the display area of the shifted display pixel of the screen image IMF is equivalent to the red sub-pixel R3, green sub-pixel G3, and blue sub-pixel B2 of the pixel PPX3, which is the size of the screen image IMF The display area of the shifted pixel spans the area where the single pixel PPX3 is located. At this time, the compensation circuit 140 may not generate compensation sub-pixels.
