mCd)，則晝素220與221需分別分攤400 mCd的綠色亮度。 若列虛擬晝素243所對應的色彩為橘色，亮度為500 mCd， 則晝素221與222需分別分攤250 mCd的橘色亮度。 因此，當大型LED顯示器20顯示各列虛擬晝素24時， ❹晝素220需顯示列虛擬晝素241 —半的色彩亮度，即400 mCd的綠色亮度；晝素221需顯示列虛擬晝素241及列虛 擬晝素243各一半的色彩亮度，即400 mCd的綠色亮度及 250 mCd的橘色亮度…等等，其餘可依此類推。由於觀賞 者在適當距離觀賞時，因人眼的辨識能力無法將晝素220 與221及221與222等相鄰的晝素區分為獨立的光點，故 可藉由相鄰晝素的色彩亮度組合出各列虛擬晝素的效果。 同理，當大型LED顯示器20顯示行虛擬晝素26時， 各行虛擬晝素（例如261、263)之色彩亮度亦可由其相鄰之 7 201037655 晝素如220與223及223與226分攤。 欲顯示各交叉虛擬晝素28時，以交叉虛擬晝素281、 283、285及287為例。由於交叉虛擬晝素281具有等距離 的四個相鄰晝素220、221、223及224，故其所對應之色 彩亮度由晝素220、221、223及224分別分攤四分之一的 色彩亮度。 依此類推，畫素221將需顯示交叉虛擬晝素281四分 之一的色彩亮度及交叉虛擬晝素283的四分之一色彩亮 度，而晝素224則需顯示交叉虛擬晝素281、283、285及 287各四分之一的色彩亮度的總合。 以本實施例而言，大型LED顯示器20只需以其正常晝 面更新頻率（refresh rate)的四倍頻率，分別顯示各晝素 22、各列虛擬晝素24、各行虛擬晝素26及各交叉虛擬晝 素28所對應的色彩亮度，即可提供比真實晝素22高出四 倍的優良晝質。 請參閱第3圖，係本發明另一實施例之示意圖。本實 施例係於大型LED顯示器30各列之晝素300間分別橫向插 入一第一列虛擬晝素311及一第二列虛擬晝素321，且於 各行之晝素300間分別縱向插入一第一行虛擬晝素331及 一第二行虛擬晝素341。 決定橫向及縱向的虛擬晝素插入數量後，當需在各列 虛擬晝素之垂直延伸方向與各行虛擬晝素之水平延伸方向 的交叉位置分別插入一交叉虛擬晝素。亦即需於各第一列 虛擬晝素311間縱向插入一第一交叉虛擬晝素351與一第 201037655 二交叉虛擬晝素361，於各第二列虛擬晝素321間縱向插 入一第三交叉虛擬晝素371與一第四交叉虛擬晝素381， 藉以補滿行與列的空間。 ' 本實施例主要係利用虛擬晝素與相鄰晝素300間距離 之反比的方式來分攤色彩亮度，藉以模擬虛擬晝素在空間 上的位置分佈。 其中，第一列虛擬晝素311可以晝素301分攤其所對 應色彩亮度的三分之二，以晝素303分攤其所對應色彩亮 ®度的三分之一。第二列虛擬晝素321則以晝素301分攤其 所對應色彩亮度的三分之一，以晝素303分攤其所對應色 彩亮度的三分之二。 第一行虛擬晝素331可以晝素301分攤其所對應色彩 亮度的三分之二，以晝素305分攤其所對應色彩亮度的三 分之一。第二行虛擬晝素341則以晝素301分攤其所對應 色彩亮度的三分之一，以晝素305分攤其所對應色彩亮度 ❹的三分之二。 第一交叉虛擬晝素351則需以晝素301分攤其所對應 色彩亮度的三分之一，以晝素307分攤其所對應色彩亮度 的六分之一，以晝素303與305分別分攤其所對應色彩亮 度的四分之一。第二交叉虛擬晝素361需以晝素305分攤 其所對應色彩亮度的三分之一，以晝素3 0 3分攤其所對應 色彩亮度的六分之一，以晝素301與307分別分攤其所對 應色彩亮度的四分之一。 第三交叉虛擬晝素371需以晝素303分攤其所對應色 9 201037655 彩亮度的三分之一，以畫素305分攤其所對應色彩亮度的 六分之一，以畫素301與307分別分攤其所對應色彩亮度 的四分之一。第四交又虛擬晝素381需以畫素307分攤其 所對應色彩亮度的三分之一，以晝素301分攤其所對應色 彩亮度的六分之一，以晝素3 0 3與3 0 5分別分攤其所對應 色彩亮度的四分之一。 各畫素點位及各虛擬晝素點位之顯示方式確定後，只 需分時顯示各晝素點位及各虛擬晝素點位所對應的色彩亮 度，即可得到晝質極高的晝面。由於晝素點位與虛擬晝素 點位共為原晝素點位的九倍，故需以正常晝面更新頻率的 九倍頻率分別加以顯示。 請參閱第4圖，係本發明另一實施例之示意圖。本實 施例中，在大型LED顯示器40中選擇插入虛擬晝素之方式 與前述各實施例相同，惟，各虛擬晝素之點位決定後，其 對應之色彩亮度的分攤方式與前述各實施例不同。在此以 橫向縱向分別插入一列虛擬晝素及一行虛擬晝素為例說 明。 一般肉眼可辨識範圍為觀賞距離的3400分之一至 1700分之一，故LED顯示器之製作規格的最低要求，觀賞 距離最佳應為晝素間距415的3400倍以上，最小可接受距 離則應大於晝素間距415的1700倍。亦即，當晝素間距 415為5公分時，其觀賞距離應大於85公尺。 當大型LED顯示器40之晝素間距415為5公分，但其 設置之觀賞距離為255公尺（即三倍於正常觀賞距離）時， 10 201037655 肉眼之可辨識範圍約為15公分，。此時，各虛擬晝素44 所對應之色彩亮度可選擇由位於該虛擬畫素44辨識範圍 445以内的晝素421至428共同分攤。而辨識範圍445以 ' 内晝素421至428的分攤方式，亦可依需求選擇為平均分 攤、依距離之反比分攤、依距離之平方反比分攤及其他分 攤方式。 當各虛擬晝素之插入點位決定後，只需依設定的分攤 方式，分時顯示各晝素及各位置之虛擬晝素所對應之色彩 ®亮度，即可達到高晝質顯示的目的。 請參閱第5圖，係本發明一實施例之流程圖。本發明 之一精神係利用實體晝素分攤虛擬晝素之色彩亮度，並以 分時顯示的方式分別顯示各晝素及各虛擬晝素。 如圖所示，本發明之方法係依影像之規格選擇各列之 晝素間需插入的列虛擬晝素的數量，以及各行之畫素間需 插入的行虛擬晝素的數量，如步驟501及步驟503。 0 列虛擬晝素與行虛擬晝素插入之數量確定後，需於各 列虛擬晝素之垂直延伸方向與各行虛擬晝素之水平延伸方 向的交叉位置分別插入交叉虛擬晝素，藉以補滿顯示所需 之晝素及虛擬晝素之陣列，如步驟505。 本發明之另一重點為虛擬晝素的表現方式，其主要係 以實體晝素分攤虛擬晝素之色彩亮度，而分攤之方式則有 多種可供選擇。例如：可選擇以各虛擬晝素相鄰之晝素依 距離之反比分攤其所對應之色彩亮度。當大型LED顯示裝 置之晝素間距小於可辨識範圍時，則可利用各虛擬晝素鄰 11 201037655 L可辨識範ϋ内之晝素分攤其對應之色彩亮度。其分擁方 式可選擇依距離之反比分攤、依平均分攤或依距離之平方 反比分攤等分攤方式。如步驟507。 、士確疋虛擬旦素之插入數量、位置及分攤方式後，則以 守,'、、員示的方式分別顯示各晝素及各虛擬晝素，如步驟 509。 —以上所述者，僅為本發明之實施例而已，並非用來限 定本發明只靶之範圍，即凡依本發明申請專利範圍所述之 形狀、構造、特徵、精神及方法所為之均等變化與修飾， 均應包括於本發明之申請專利範圍内。 【圖式簡單說明】 第1圖.係習用LED顯示器之虛擬晝素示意圖。 第2圖：係本發明一實施例之示意圖。 ，3圖：係本發明另一實施例之示意圖。Due to the continuous improvement of the manufacturing technology of the light-emitting diode (LED), the light-emitting diodes can display the color, brightness and lifespan of the light-emitting diodes, and the cost is relatively low. Many large-area or outdoor-mounted displays have been Replaced by a diode display. X Please refer to Figure 1 for a schematic diagram of a virtual element of a conventional LED display.

The main purpose is to set the red LEDs 12 and 127 of the respective elements 12 to be placed above and below the halogen 12, and the green LED 123 and the blue LED 125 are respectively disposed on the left and right of the halogen 12 A diamond setting is formed and the individual halogens 12 are closely arranged. With this arrangement, a virtual element 14 can be formed between adjacent two halogens 12 in the same column. The virtual pixel 14 uses a blue LED 125 of the left side halogen 12, a green LED 143 of the right side, a lower red LED Ϊ 41 of the upper pixel, and an upper red LED 145 of the lower element.

However, the newly emerging large-scale LED display has a distance of about 5 cm to 1 Gcm or more depending on the distance between the pixels and the pixels. This type of large LED shows that the thermal method uses the conventional virtual element driving method because the cells are not closely arranged.

The purpose of crying is to provide a large-scale light-emitting diode display; the color of the light in the range of the identification is based on the distance and the color brightness corresponding to the virtual element. In order to achieve the above object, the present invention provides a large-sized light-emitting diode display, which comprises a plurality of i-array displays, a predetermined spacing between adjacent pixels, and a display method thereof. 3 has the following steps: select the number of virtual pixels inserted between the columns of each column, select the number of virtual pixels inserted between the cells of each row; the vertical direction of each virtual pixel and the virtual pixels of each row The parent fork position of the horizontal extension direction is respectively inserted into a cross virtual pixel; and the time division displays each column of virtual denier, row virtual pixel and cross virtual pixel, wherein each virtual element is divided by adjacent pixels.

The present invention further provides a display method for a large-scale light-emitting diode display, the large-sized light-emitting diode display comprising a plurality of pixels, arranged in an array, and a predetermined spacing between adjacent pixels, the display method comprising the same The following steps: select the number of virtual pixels inserted between the columns of each column; select the number of virtual pixels inserted between the cells of each row; extend the vertical direction of each virtual pixel and the horizontal level of each row of virtual pixels The intersections of the directions are respectively inserted into a cross-virtual element; and the time-series display of each column of virtual elements, rows of virtual elements, and cross-virtual elements, wherein each virtual element is distributed by a neighboring element within a recognizable range The color brightness corresponding to the virtual element. 5 201037655 [Embodiment] First, please refer to Fig. 2, which is a schematic view of an embodiment of the present invention. As shown, the large-scale light-emitting diode (LED) display 20 includes a plurality of halogens 22, each of which is arranged in an array, with a pixel pitch between adjacent cells 22 . Among them, the pixel spacing 21 varies depending on the viewing distance of the large LED display 20 design, and is generally about 5 cm to 10 cm, or even further. In the case of a full-color LED display, one of its elements should include at least one red LED, one green LED and one blue LED. A white LED can be added as needed. The quality of the large LED display 20 can be displayed, mainly depending on the amount of information that can be provided when displaying a face. In general, the more the pixels 22 of the large LED display 20, the more information can be provided in one screen, and the better the quality of the display. However, the more the halogen 22 represents the more LEDs used, the higher the cost, especially the LEDs required for large LED displays 20. Therefore, if more information can be provided by using virtual pixels in the case of less than 22, then the quality of the quality can be considered at the same time, and the cost can be maintained within a reasonable range. The display method of the large-sized LED display 20 of the present invention is mainly based on the original device architecture, and the mode of inserting the virtual element is selected according to the requirement of playing the face. One or more columns of virtual elements (dotted twill dots) 24 may be laterally inserted between each element (solid line point) 22, or one or more rows of virtual elements may be inserted longitudinally between the elements 12 ( Dotted horizontal stripes point) 26. In this embodiment, a virtual matrix 24 is inserted horizontally and a virtual pixel 201037655 26 is inserted longitudinally as an example. When both the horizontal and vertical directions are selected to insert a virtual element, it is necessary to insert a cross virtual pixel (dotted point) at the intersection of the vertical extension direction of each column of virtual elements 24 and the horizontal extension direction of each row of virtual elements 26 respectively. 28, to fill the space between the rows and columns. After the position and quantity of the virtual element are inserted, the effect of the visual persistence is used to display the color and brightness of each element 22 and the virtual element of each position in a time-sharing manner, which can make the viewer get higher. Quality visual effects. ® wherein each column of virtual elements 24 can share its color brightness by one-half of its neighboring elements. For example, if the color corresponding to the virtual element 241 is green and the brightness is 800 microcandela (mCd), then the pixels 220 and 221 need to share the green brightness of 400 mCd. If the color corresponding to the virtual element 243 is orange and the brightness is 500 mCd, then the pixels 221 and 222 need to respectively distribute the orange brightness of 250 mCd. Therefore, when the large LED display 20 displays each column of virtual pixels 24, the pixel 220 needs to display the color brightness of the column virtual element 241-half, that is, the green brightness of 400 mCd; the pixel 221 needs to display the column virtual element 241. And the color brightness of each half of the virtual element 243, that is, the green brightness of 400 mCd and the orange brightness of 250 mCd, etc., and so on. Since the viewer can not distinguish the adjacent pixels of 昼素220 and 221 and 221 and 222 into independent spots because of the recognition ability of the human eye, the color brightness of adjacent pixels can be used. Combine the effects of each column of virtual pixels. Similarly, when the large LED display 20 displays the virtual pixels 26, the color brightness of each row of virtual pixels (e.g., 261, 263) can also be shared by its adjacent 7 201037655 elements such as 220 and 223 and 223 and 226. For example, when the virtual virtual elements 28 are displayed, the virtual virtual elements 281, 283, 285, and 287 are taken as an example. Since the cross virtual pixels 281 have four adjacent pixels 220, 221, 223, and 224 equidistant, the corresponding color brightness is divided by a quarter of the color brightness by the pixels 220, 221, 223, and 224, respectively. . And so on, the pixel 221 will need to display the color brightness of one quarter of the cross virtual element 281 and the quarter color brightness of the cross virtual element 283, while the pixel 224 needs to display the cross virtual element 281, 283 The sum of the color hues of each of 285 and 287. In the present embodiment, the large-sized LED display 20 only needs to display each element 22, each column of virtual elements 24, each row of virtual elements 26, and each of four times of its normal face refresh rate (refresh rate). By crossing the color brightness corresponding to the virtual element 28, it can provide an excellent quality four times higher than the real element. Please refer to FIG. 3, which is a schematic view of another embodiment of the present invention. In this embodiment, a first column of virtual pixels 311 and a second column of virtual pixels 321 are laterally inserted between the cells 300 of each of the large LED displays 30, and a vertical insertion is performed between the cells 300 of each row. A row of virtual pixels 331 and a second row of virtual pixels 341. After determining the number of virtual pixel insertions in the horizontal and vertical directions, a cross virtual pixel is inserted in the vertical direction of each column of virtual pixels and the horizontal extension direction of each row of virtual pixels. In the first column of virtual pixels 311, a first cross virtual pixel 351 and a first 201037655 two cross virtual pixel 361 are inserted longitudinally, and a third cross is inserted longitudinally between each second column of virtual pixels 321 The virtual element 371 and a fourth cross virtual element 381 complement the space of the row and column. The present embodiment mainly uses the inverse ratio of the distance between the virtual pixels and the adjacent pixels 300 to distribute the color brightness, thereby simulating the spatial distribution of the virtual pixels in space. Among them, the first column of virtual pixels 311 can share the two-thirds of the corresponding color brightness of the pixel 301, and the 303 of the corresponding color brightness is divided by one third of the corresponding color. The second column of virtual pixels 321 distributes one-third of the brightness of the corresponding color with the pixel 301, and distributes two-thirds of the brightness of the corresponding color with the element 303. The first row of virtual pixels 331 can be divided into two-thirds of the corresponding color brightness of the element 301, and one-third of the corresponding color brightness is distributed by the element 305. In the second line, the virtual element 341 distributes one-third of the corresponding color brightness with the 301, and the two-thirds of the corresponding color brightness is distributed by the 305. The first cross virtual pixel 351 needs to share the corresponding one-third of the brightness of the corresponding color with the pixel 301, and distributes one-sixth of the corresponding color brightness with the pixel 307, and separately distributes the pixels 303 and 305 thereof. A quarter of the corresponding color brightness. The second cross virtual pixel 361 needs to share the corresponding one-third of the color brightness of the corresponding color with the pixel 305, and distribute the corresponding brightness of the corresponding color by one-third of the corresponding color, and separately share the pixels 301 and 307. It corresponds to a quarter of the color brightness. The third cross virtual 昼 371 needs to share the corresponding color 9 201037655 color brightness with 昼 303, and divide the corresponding color brightness by one-sixth with the pixel 305, respectively, with pixels 301 and 307 respectively A quarter of the brightness of the corresponding color is shared. The fourth intersection and the virtual element 381 need to share the corresponding one-third of the brightness of the corresponding color with the pixel 307, and distribute the corresponding brightness of the color by one-sixth of the corresponding color, with the pixels 3 0 3 and 3 0 5 respectively share a quarter of the corresponding color brightness. After the display of each pixel point and each virtual pixel point is determined, it is only necessary to display the color brightness corresponding to each pixel point and each virtual pixel point in time, and the enamel is extremely high. surface. Since the pixel points and the virtual pixel points are nine times the original pixel point, they need to be displayed at nine times the normal face update frequency. Please refer to FIG. 4, which is a schematic view of another embodiment of the present invention. In this embodiment, the manner of inserting the virtual pixels in the large-sized LED display 40 is the same as that of the foregoing embodiments. However, after the points of the virtual pixels are determined, the corresponding color brightness distribution manners and the foregoing embodiments are different. Here, a series of virtual pixels and a row of virtual pixels are inserted in the horizontal and vertical directions as an example. Generally, the visible range of the naked eye is from 3400 to 1700 of the viewing distance. Therefore, the minimum requirement for the production specifications of the LED display should be 3400 times or more of the pixel spacing 415, and the minimum acceptable distance should be greater than The pixel spacing is 1700 times the pitch of 415. That is, when the pixel spacing 415 is 5 cm, the viewing distance should be greater than 85 meters. When the pixel spacing 415 of the large LED display 40 is 5 cm, but the viewing distance is 255 meters (i.e., three times the normal viewing distance), the visible range of the 10 201037655 is about 15 cm. At this time, the color brightness corresponding to each virtual element 44 can be jointly shared by the pixels 421 to 428 located within the recognition range 445 of the virtual pixel 44. The identification range 445 is based on the distribution method of 昼 昼 421 to 428, and can also be selected as the average distribution, the inverse ratio according to the distance, the inverse square of the distance, and other allocation methods. After the insertion point of each virtual element is determined, it is only necessary to display the color ® brightness corresponding to each element and the virtual element of each position according to the set distribution mode, so as to achieve the purpose of high quality display. Please refer to FIG. 5, which is a flow chart of an embodiment of the present invention. One of the spirits of the present invention is to use the entity element to share the color brightness of the virtual element, and to display each element and each virtual element in a time-sharing manner. As shown in the figure, the method of the present invention selects the number of columns of virtual pixels to be inserted between the pixels of each column according to the specification of the image, and the number of rows of virtual pixels to be inserted between the pixels of each row, as in step 501. And step 503. After the number of virtual pixels and the row of virtual pixels are determined, the intersection of the vertical direction of each virtual element and the horizontal extension direction of each row of virtual elements is inserted into the virtual virtual element to complement the display. The desired array of elements and virtual elements, as in step 505. Another key point of the present invention is the representation of virtual pixels, which mainly share the color brightness of virtual pixels with physical elements, and there are many ways to share the modes. For example, you can choose to share the corresponding color brightness according to the inverse ratio of the neighboring pixels of each virtual element. When the pixel spacing of the large LED display device is less than the identifiable range, the corresponding color brightness can be shared by the virtual pixels in the virtual matrix 11 201037655 L. The distribution method can be divided according to the inverse ratio of the distance, the average distribution, or the square of the distance. As step 507. After the number, position and allocation method of the virtual denier, the individual elements and the virtual elements are displayed in the manner of ', ', and the member, as shown in step 509. The above is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the shape, structure, characteristics, spirit, and method described in the scope of the present invention are equally varied. And modifications are intended to be included in the scope of the present invention. [Simple description of the figure] Figure 1. A schematic diagram of a virtual pixel of a conventional LED display.
