The method for inspecting a large screen includes the following steps: inspecting the display units; determining whether the display units are faulty; and replacing the positions of the faulty display units among the display units that are determined to be faulty with the normal display units that are located closest to the periphery of the array and are determined to be normal.
Description
本發明係與屏幕的檢修方法有關;特別是指一種大型屏幕的檢修方法。The present invention relates to a method for inspecting and repairing a screen, and in particular to a method for inspecting and repairing a large screen.
已知顯示器的發展日趨成熟,目前已廣泛應用於大型顯示屏幕,舉例來說,一般大型屏幕(如球幕)是由大量的LED顯示器設置於支架上拼接而成,以提供觀賞者身處於其中時能具有大視角的視覺震撼和身臨其境的觀影感受。The development of known displays is becoming more and more mature, and has been widely used in large display screens. For example, a general large screen (such as a dome screen) is composed of a large number of LED displays installed on a bracket to provide viewers with a wide viewing angle and an immersive viewing experience.
在使用過程中,難免有部分的LED顯示器產生故障的問題,當大型屏幕中之部分LED顯示器故障時,會使得大型屏幕所呈現之畫面產生例如區域性的畫面閃爍或是亮度過暗等缺陷,進而影響呈現效果及供觀賞者的觀影感受。During use, it is inevitable that some LED displays will malfunction. When some LED displays in a large screen malfunction, the image displayed on the large screen will have defects such as regional image flickering or too dark brightness, thereby affecting the presentation effect and the viewing experience of the audience.
而當維修人員將故障的LED顯示器取下支架進行後續檢修時,大型屏幕的畫面就會呈現不完整的狀態,進而無法進行展示或是造成展示品質不佳,因此,維修單位便會需要囤積多組維修備品,藉以即時更換故障之LED顯示器,以避免上述情形發生;然而,如球幕等特殊結構之大型屏幕,每一列的LED顯示器形狀都不相同,若是囤積太多備品將會影響倉儲空間與養護成本,故一般維修單位僅會針對每一種形狀設置1至2組備品,如此一來,當球幕上的LED顯示器同時故障的數量過多時,將會導致備品不足以更換所有故障的LED顯示器,除了無法即時更換維修完成以提供高品質的顯示畫面外,訂購、運送備品等情事亦造成維修的時程拉的更長,如此一來,勢必長期影響大型屏幕所呈現之畫面品質及觀賞者的觀影感受。因此,如何提供一種大型屏幕的檢修方法,使得維修單位不用囤積過多備品,且當LED顯示器故障時,仍能在短時間內提供高品質的顯示畫面,是亟待解決的問題。When maintenance personnel remove the bracket of the faulty LED display for subsequent maintenance, the image on the large screen will be incomplete, and the display will not be able to be displayed or the display quality will be poor. Therefore, the maintenance unit will need to stock up on multiple sets of maintenance spare parts to replace the faulty LED display immediately to avoid the above situation. However, for large screens with special structures such as domes, the shapes of each row of LED displays are different. If too many spare parts are stocked, it will affect the storage space. Due to the high maintenance cost, general maintenance units will only set up 1 to 2 sets of spare parts for each shape. In this way, when too many LED displays on the dome fail at the same time, there will be insufficient spare parts to replace all the failed LED displays. In addition to being unable to replace and repair them immediately to provide high-quality display images, the ordering and transportation of spare parts will also cause the maintenance schedule to be longer. This will inevitably affect the image quality presented by the large screen and the viewing experience of the audience for a long time. Therefore, how to provide a large screen inspection method so that the maintenance unit does not need to stockpile too many spare parts and can still provide high-quality display images in a short time when the LED display fails is an urgent problem to be solved.
有鑑於此,本發明之目的在於提供一種大型屏幕的檢修方法,當大型屏幕中之顯示單元故障時,仍能在短時間內提供高品質的顯示畫面。In view of this, the purpose of the present invention is to provide a large-screen inspection method, when the display unit in the large-screen fails, it can still provide a high-quality display image in a short time.
緣以達成上述目的,本發明提供的一種大型屏幕的檢修方法,該大型屏幕包含複數顯示單元,該些顯示單元以一陣列方式排列,該陣列由複數直行及複數橫列組成,該大型屏幕的檢修方法包含以下步驟:檢測該些顯示單元;判斷該些顯示單元是否故障;以及將該些顯示單元中被判斷為故障之故障顯示單元與設置於該陣列最接近外圍且被判斷為正常之正常顯示單元相互置換設置位置。In order to achieve the above-mentioned purpose, the present invention provides a method for repairing a large screen, wherein the large screen comprises a plurality of display units, wherein the display units are arranged in an array, wherein the array is composed of a plurality of vertical rows and a plurality of horizontal rows, and wherein the method for repairing the large screen comprises the following steps: detecting the display units; determining whether the display units are faulty; and replacing the positions of the faulty display units among the display units that are determined to be faulty with the normal display units that are arranged at the periphery of the array and are determined to be normal.
本發明另提供一種使用前述檢修方法之大型屏幕,定義一範圍,該範圍是自該陣列之外周緣向內延伸之範圍,所有位於接近該陣列外圍之故障顯示單元皆位於該範圍中,該大型屏幕播放影像時,該範圍中之所有顯示單元皆不顯示、顯示黑色或是被遮蔽。The present invention further provides a large screen using the above-mentioned inspection method, defining a range, which is a range extending inward from the outer periphery of the array, and all faulty display units located near the outer periphery of the array are located in the range. When the large screen plays images, all display units in the range do not display, display black or are blocked.
本發明之效果在於,透過將故障顯示單元與設置於該陣列最接近外圍之正常顯示單元相互置換設置位置的方式,能將故障顯示單元先移置該大型屏幕之外緣,以大幅降低故障顯示單元對整體畫面呈現之破壞,最大化的保持該大型屏幕所呈現之畫面的完整性,並能在故障顯示單元暫未完成維修時提供高品質的顯示畫面,以改善當該陣列中故障顯示單元的數量過多時,備品不足以更換所有故障顯示單元的問題,使用者也不需於倉儲中囤積過多備品以備更換,進而能達到降低養護成本之目的,且維修人員能在充裕的時間下針對故障顯示單元進行檢修,進而能達成減少維修人員之人數配置,以及降低維修人員工作負擔之效果;而該大型屏幕播放影像時,透過該範圍中之所有顯示單元皆不顯示、顯示黑色或是被遮蔽之技術手段,能使得該大型屏幕顯示畫面之外緣,以平滑的狀態呈現,而不會受故障顯示單元的影響而呈現鋸齒狀,藉此以提供高品質的顯示畫面,增進觀賞者的觀影感受。The effect of the present invention is that, by replacing the positions of the faulty display unit with the normal display unit located closest to the periphery of the array, the faulty display unit can be first moved to the outer edge of the large screen, thereby greatly reducing the damage of the faulty display unit to the overall image presentation, maximizing the integrity of the image presented by the large screen, and providing a high-quality display image when the faulty display unit is not yet repaired, so as to improve the problem that when there are too many faulty display units in the array, the spare parts are not enough to replace all the faulty display units, and the user does not need to stockpile too many spare parts in the warehouse. The large screen can be equipped with replacement parts for replacement, thereby achieving the purpose of reducing maintenance costs, and maintenance personnel can repair faulty display units in ample time, thereby achieving the effect of reducing the number of maintenance personnel and reducing the workload of maintenance personnel; and when the large screen plays images, through the technical means that all display units in the range are not displayed, displayed in black or are shielded, the outer edge of the large screen display screen can be presented in a smooth state, and will not be affected by the faulty display unit and appear jagged, thereby providing a high-quality display screen and enhancing the audience's viewing experience.
為能更清楚地說明本發明,茲舉較佳實施例並配合圖式詳細說明如後。請參考圖1所示,為本發明一較佳實施例之大型屏幕1的檢修方法的流程圖。In order to explain the present invention more clearly, a preferred embodiment is given and described in detail with reference to the drawings. Please refer to FIG1 , which is a flow chart of a method for repairing a large screen 1 according to a preferred embodiment of the present invention.
如圖2所示,該大型屏幕1包含複數顯示單元10,於本實施例中,各該顯示單元10是以LED顯示器為例說明,於其他實施例中,不排除顯示單元10為其他種類之顯示器;除此之外,於本實施例中,該大型屏幕1是以複數個LED顯示器拼接於一支架2上所形成之一球幕為例說明,實務上,該大型屏幕1也可以是例如平面等其他形狀的屏幕。As shown in FIG. 2 , the large screen 1 includes a plurality of display units 10. In the present embodiment, each of the display units 10 is illustrated as an example of an LED display. In other embodiments, it is not excluded that the display unit 10 is other types of displays. In addition, in the present embodiment, the large screen 1 is illustrated as an example of a spherical screen formed by splicing a plurality of LED displays on a bracket 2. In practice, the large screen 1 may also be a screen of other shapes such as a plane.
該些顯示單元10以一陣列方式排列,該陣列由複數直行及複數橫列組成;進一步說明的是,於本實施例中,如圖3所示,該陣列包含第一部分P1、第二部分P2、第三部分P3、第四部分P4及第五部分P5,各該部份可以是由不同數量之直行或不同數量之橫列組成,例如該第一部分是由64個直行(X1,X2,X3…X64)及60個橫列(Y1,Y2,Y3…Y60)所組成,而該第二部分是由32個直行(X’1,X’2,X’3…X’32)及11個橫列(Y’1,Y’2,Y’3…Y’11)所組成,於其他實施例中,該陣列可以是由複數個部份或是僅由一個部分組成。The display units 10 are arranged in an array, and the array is composed of a plurality of vertical rows and a plurality of horizontal rows. To further explain, in this embodiment, as shown in FIG. 3 , the array includes a first portion P1, a second portion P2, a third portion P3, a fourth portion P4, and a fifth portion P5. Each portion may be composed of a different number of vertical rows or a different number of horizontal rows. For example, the first portion is composed of 64 The first part is composed of 32 columns (X’1, X’2, X’3…X’32) and 11 rows (Y’1, Y’2, Y’3…Y’11). In other embodiments, the array may be composed of multiple parts or only one part.
該大型屏幕1的檢修方法包含以下步驟:The maintenance method of the large screen 1 comprises the following steps:
步驟S02,檢測該些顯示單元10;請參閱圖2,於本實施例中,是於該大型屏幕1前方設置一攝影裝置3,並透過將該大型屏幕1上所有的顯示單元全部點亮後,以該攝影裝置3拍攝該大型屏幕1上所有的顯示單元,並將拍攝之影像傳輸至一運算主機4,並利用影像辨識之方式進分析。當然,除了全部顯示單元同時點亮外,為達到較精準的檢查,亦可利用分別逐列點亮之方式進行每一橫列的拍攝,直到該大型屏幕1中每一橫列之顯示單元都完成檢測;實務上亦不排除透過分別逐行點亮之方式進行每一直行的拍攝,直到該大型屏幕1中每一直行之顯示單元都完成檢測;除此之外,也不排除以如區塊式點亮等其他方式檢測該些顯示單元。必須說明的是,除利用攝影配合影像辨識之方式外,也可以用人工直接進行肉眼判斷來達到相同目的。Step S02, detect the display units 10; please refer to Figure 2. In this embodiment, a camera device 3 is set in front of the large screen 1, and after all the display units on the large screen 1 are all lit up, the camera device 3 is used to photograph all the display units on the large screen 1, and the photographed image is transmitted to a computing host 4 and analyzed using image recognition. Of course, in addition to lighting up all display units at the same time, in order to achieve a more accurate inspection, each row can be photographed by lighting up each row one by one until all display units in each row of the large screen 1 are inspected; in practice, it is not excluded to light up each row one by one until all display units in each row of the large screen 1 are inspected; in addition, it is not excluded to inspect these display units by other methods such as block lighting. It must be explained that in addition to using photography combined with image recognition, the same purpose can also be achieved by direct human visual judgment.
步驟S04,判斷該些顯示單元10是否故障;於本實施例中,是利用該運算主機4接受到該攝影裝置3之影像後,分析影像畫面中是否有符合故障定義之顯示單元,而後,進一步地記錄被判斷為故障之顯示單元的位置,並形成一紀錄資料輸出(配合圖3);其中,判斷故障之基準能由使用者自行定義,例如,可以是各該顯示單元10中包含大於三點之像素損壞時即判斷顯示單元為故障顯示單元。Step S04, determining whether the display units 10 are faulty; in the present embodiment, after receiving the image from the photographic device 3, the computing host 4 analyzes whether there are display units in the image that meet the definition of fault, and then further records the positions of the display units determined to be faulty, and forms a record data output (with FIG. 3); wherein, the criterion for determining a fault can be defined by the user, for example, when each of the display units 10 contains more than three damaged pixels, the display unit is determined to be a faulty display unit.
於本實施例中,是以各該顯示單元10中包含一點以上且小於等於3點之像素損壞時判斷為第一級故障,各該顯示單元10中包含大於3點之像素損壞時判斷為第二級故障為例說明,且於該紀錄資料中被判斷為第一級故障之顯示單元位置標示形式與被判斷為第二級故障之顯示單元位置標示形式相異,如圖3所示,被判斷為正常之顯示單元位置以白色表示,被判斷為第一級故障之顯示單元位置以黑色方塊的形式標示,被判斷為第二級故障之顯示單元位置則以灰色方塊的形式標示,藉此,維修人員根據該紀錄資料能清楚得知所有故障顯示單元的位置以及該些故障顯示單元的損壞程度。In this embodiment, it is explained by taking the case where each display unit 10 contains more than one but less than or equal to 3 damaged pixels as a first level fault, and each display unit 10 contains more than 3 damaged pixels as a second level fault. In addition, the position marking form of the display unit judged as a first level fault and the position marking form of the display unit judged as a second level fault in the recorded data are different. As shown in FIG. 3, the position of the display unit judged as normal is indicated in white, the position of the display unit judged as a first level fault is marked in the form of a black square, and the position of the display unit judged as a second level fault is marked in the form of a gray square. In this way, maintenance personnel can clearly know the positions of all faulty display units and the degree of damage of these faulty display units based on the recorded data.
步驟S06,將該些顯示單元10中被判斷為故障之故障顯示單元與設置於該陣列最接近外圍且被判斷為正常之正常顯示單元相互置換設置位置;舉例來說,維修人員能基於該紀錄資料之紀錄,將一個故障顯示單元及設置於該陣列最接近外圍的一個正常顯示單元拆離該支架後,相互調換兩者於該支架2上之安裝位置,並重複前述動作直到所有故障顯示單元都移至最接近該大型屏幕1之外緣處,藉此,能如圖4所示將故障顯示單元移至該大型屏幕1之外緣,以最大化的保持該大型屏幕畫面呈現之完整性,進而能在故障顯示單元暫未完成維修時提供高品質的顯示畫面,並能改善當該陣列中故障顯示單元的數量過多時,備品不足以更換所有故障顯示單元的問題,使用者也不需於倉儲中囤積過多備品以備更換,進而能達到降低養護成本之目的。再說明的是,若該些顯示單元中之故障顯示單元位於該陣列之最外圍,則位於該陣列之最外圍的顯示單元可保持不動。Step S06, swap the positions of the faulty display units 10 that are judged to be faulty with the normal display units that are located closest to the periphery of the array and judged to be normal; for example, based on the record of the record data, the maintenance personnel can remove a faulty display unit and a normal display unit located closest to the periphery of the array from the bracket, swap the installation positions of the two on the bracket 2, and repeat the above-mentioned actions until all the faulty display units are moved to the nearest periphery of the array. The outer edge of the large screen 1, thereby, as shown in FIG. 4, the faulty display unit can be moved to the outer edge of the large screen 1 to maximize the integrity of the large screen image presentation, thereby providing a high-quality display image when the faulty display unit is not yet repaired, and improving the problem that when there are too many faulty display units in the array, the spare parts are not enough to replace all the faulty display units, and the user does not need to store too many spare parts in the warehouse for replacement, thereby achieving the purpose of reducing maintenance costs. It is further explained that if the faulty display unit among the display units is located at the outermost periphery of the array, the display units located at the outermost periphery of the array can remain unchanged.
於本實施例中,在步驟S06中進一步包含,將各該橫列中之故障顯示單元與設置於同一橫列中最接近外圍且被判斷為正常之正常顯示單元相互置換設置位置。也就是說,維修人員能將同一橫列中的一個故障顯示單元及設置於同一橫列中最接近外圍的一個正常顯示單元拆離該支架2後,相互調換兩者於該支架2上之安裝位置,並重複前述動作直到同一橫列中所有故障顯示單元都移至最接近該大型屏幕1之外緣處,以及於包含有故障顯示單元的所有橫列中執行前述動作,直到該陣列中所有故障顯示單元都移至最接近該大型屏幕之外緣處。In this embodiment, step S06 further includes exchanging the positions of the faulty display units in each row with the normal display units that are located in the same row and closest to the periphery and are judged to be normal. That is, the maintenance personnel can remove a faulty display unit in the same row and a normal display unit located in the same row and closest to the periphery from the bracket 2, and then exchange the installation positions of the two on the bracket 2, and repeat the above actions until all the faulty display units in the same row are moved closest to the outer edge of the large screen 1, and perform the above actions in all rows containing faulty display units until all the faulty display units in the array are moved closest to the outer edge of the large screen.
於其他實施例中,若該大型屏幕是由形狀相同之顯示單元組成,也可以不限制在同一橫列中互換故障顯示單元及正常顯示單元的設置位置;舉例來說,也可以是在同一直行中互換故障顯示單元及正常顯示單元的設置位置,或者跨行、跨列的互換故障顯示單元及正常顯示單元的設置位置,一樣能達成將故障顯示單元移至大型屏幕之外緣,以最大化的保持該大型屏幕畫面呈現之完整性之目的。In other embodiments, if the large screen is composed of display units of the same shape, it is not limited to interchange the setting positions of the faulty display units and the normal display units in the same horizontal row; for example, it is also possible to interchange the setting positions of the faulty display units and the normal display units in the same vertical row, or interchange the setting positions of the faulty display units and the normal display units across rows and columns, which can also achieve the purpose of moving the faulty display units to the outer edge of the large screen to maximize the integrity of the large screen image presentation.
再說明的是,於本實施例中,在步驟S06中進一步包含,當同一橫列中之故障顯示單元數量為偶數時,將故障顯示單元之數量平均分配後分別移至同一橫列之相對兩側,當同一橫列中故障顯示單元數量為奇數時,將故障顯示單元之數量分配為N及N+1個並分別移至同一橫列之相對兩側與被判斷為正常之正常顯示單元相互置換設置位置;較佳者,當同一橫列中故障顯示單元數量為奇數時,將N個顯示單元移至同一橫列之相對兩側中之一第一側1b以及將N+1個顯示單元移至同一橫列之相對兩側中之一第二側1a與被判斷為正常之正常顯示單元相互置換設置位置。It is to be noted that in this embodiment, step S06 further includes that when the number of fault display units in the same row is an even number, the number of fault display units is evenly distributed and moved to two opposite sides of the same row, and when the number of fault display units in the same row is an odd number, the number of fault display units is distributed into N and N+1 and moved to two opposite sides of the same row, respectively. Preferably, when the number of faulty display units in the same row is an odd number, N display units are moved to a first side 1b, one of the two opposite sides of the same row, and N+1 display units are moved to a second side 1a, one of the two opposite sides of the same row, and are replaced with the normal display units judged to be normal.
舉例來說,如圖3所示,於橫列Y5中,故障顯示單元之數量為8個,也就是偶數,因此,將4個故障顯示單元移置橫列Y5之該第一側1b最外緣,以及將4個故障顯示單元移置橫列Y5之該第二側1a最外緣(配合圖4);而於橫列Y11中,如圖3所示,故障顯示單元之數量為3個,也就是奇數,因此,將橫列Y11中1個故障顯示單元移置橫列Y11之該第一側1b最外緣,以及將橫列Y11中2個故障顯示單元移置橫列Y11之該第二側1a最外緣(配合圖4);藉此,以大致平均分配故障顯示單元之設置位置,使得該大型屏幕畫面能最大化的完整呈現。For example, as shown in FIG3 , in row Y5, the number of fault display units is 8, which is an even number. Therefore, 4 fault display units are moved to the outermost edge of the first side 1b of row Y5, and 4 fault display units are moved to the outermost edge of the second side 1a of row Y5 (in conjunction with FIG4 ); and in row Y11, as shown in FIG3 , the number of fault display units is 3 That is, an odd number, therefore, one fault display unit in row Y11 is moved to the outermost edge of the first side 1b of row Y11, and two fault display units in row Y11 are moved to the outermost edge of the second side 1a of row Y11 (in conjunction with FIG. 4 ); thereby, the setting positions of the fault display units are roughly evenly distributed, so that the large-screen image can be presented in the maximum completeness.
於本實施例中,該步驟S06還包含同一橫列中於同一側處之故障之顯示單元被判斷為第二級故障之顯示單元相較於被判斷為第一級故障之顯示單元設置於該陣列最接近外圍處;如圖4所示,橫列Y11具有3個故障顯示單元A1,A2,A3,其中顯示單元A1被判斷為第二級故障,且顯示單元A2被判斷為第一級故障,被判斷為第二級故障之顯示單元A1相較於被判斷為第一級故障之顯示單元A2設置於最接近該第二側1a最外緣處;藉此,能將故障程度較嚴重之故障顯示單元移至最接近該大型屏幕1外緣的位置,以減低故障顯示單元對該大型屏幕1整體顯示畫面的影響。當然,除上述透過維修人員以人工作業進行顯示單元之位置置換外,在部分場合中,若維修人員不方便前往相關設置位置時,亦可利用操控機械手臂之方式來達到相同目的。此外,前述之機械手臂亦可訊號連接該運算主機4,當運算主機4分析且記錄被判斷為故障之顯示單元的位置後,更可再依據上述方法運算故障之顯示單元該與哪些未故障之顯示單元進行置換,並控制該機械手臂完成前述之置換作業。In this embodiment, the step S06 further includes placing the display units of the faults in the same row and on the same side judged as the second level faults closer to the periphery of the array than the display units judged as the first level faults; as shown in FIG4 , row Y11 has three fault display units A1, A2, and A3, wherein display unit A1 is judged as the second level fault and the display unit A2 is judged as the first level fault. The display unit A2 is judged as a first-level fault, and the display unit A1 judged as a second-level fault is set closer to the outermost edge of the second side 1a than the display unit A2 judged as a first-level fault; thereby, the faulty display unit with a more serious fault can be moved to a position closest to the outer edge of the large screen 1 to reduce the impact of the faulty display unit on the overall display screen of the large screen 1. Of course, in addition to the above-mentioned manual replacement of the display unit by maintenance personnel, in some occasions, if it is inconvenient for maintenance personnel to go to the relevant setting position, the same purpose can be achieved by controlling the robot arm. In addition, the aforementioned robot arm can also be connected to the computing host 4 via signals. After the computing host 4 analyzes and records the position of the display unit that is judged to be faulty, it can further calculate which non-faulty display units should be replaced with the faulty display unit according to the above method, and control the robot arm to complete the aforementioned replacement operation.
於本實施例中,該大型屏幕的檢修方法,包含於該步驟S06後執行一步驟S08,關閉被判斷為故障之故障顯示單元;藉此,當點亮該大型屏幕1使其工作時,被判斷為故障之故障顯示單元將不會顯示。較佳者,該些橫列中至少一者的一側具有一個位於最遠離該橫列之該側外緣之故障顯示單元,該最遠離該橫列外緣之故障顯示單元與該橫列之該側外緣間具有一最大距離,基於該最大距離定義一範圍,該範圍是自該陣列外緣徑向往內延伸大於或等於該最大距離之範圍,該步驟S08包含,關閉該範圍內所覆蓋的所有顯示單元,藉此,當點亮該大型屏幕使其工作顯示影像時,該範圍內所有顯示單元不會被點亮,如此一來,該大型屏幕1顯示畫面之外緣,能以平滑的狀態呈現,而不會因為故障顯示單元的影響而呈現鋸齒狀,藉此以提供高品質的顯示畫面,增進觀賞者的觀影感受。In this embodiment, the maintenance method of the large screen includes executing a step S08 after the step S06 to turn off the fault display unit that is judged to be faulty; thereby, when the large screen 1 is turned on to make it work, the fault display unit that is judged to be faulty will not be displayed. Preferably, at least one side of the plurality of rows has a fault display unit located farthest from the outer edge of the row, and the fault display unit farthest from the outer edge of the row has a maximum distance from the outer edge of the row. A range is defined based on the maximum distance, and the range is a range extending inward from the outer edge of the array and is greater than or equal to the maximum distance. The step S08 includes: All display units covered within the range are turned off, so that when the large screen is turned on to display images, all display units within the range will not be turned on. In this way, the outer edge of the display screen of the large screen 1 can be presented in a smooth state, and will not appear jagged due to the influence of the faulty display unit, thereby providing a high-quality display screen and enhancing the viewer's viewing experience.
於另一實施例中,該步驟S08也可以是控制故障顯示單元顯示黑色,藉此,當點亮該大型屏幕使其工作時,被判斷為故障之故障顯示單元將會顯示黑色。較佳者,基於上述,該步驟S08包含,控制該範圍內所有顯示單元顯示黑色,藉此,當點亮該大型屏幕1使其工作顯示影像時,該範圍內所有顯示單元顯示黑色,如此一來,該大型屏幕1顯示畫面之外緣,能以平滑的狀態呈現,而不會因為故障顯示單元的影響而呈現鋸齒狀,藉此以提供高品質的顯示畫面,增進觀賞者的觀影感受。In another embodiment, the step S08 may also be to control the faulty display unit to display black, whereby when the large screen is turned on to work, the faulty display unit judged to be faulty will display black. Preferably, based on the above, the step S08 includes controlling all display units in the range to display black, whereby when the large screen 1 is turned on to work to display images, all display units in the range display black, so that the outer edge of the display screen of the large screen 1 can be presented in a smooth state, and will not be jagged due to the influence of the faulty display unit, thereby providing a high-quality display screen and enhancing the viewing experience of the audience.
再於另一實施例中,該步驟S08也可以是,基於該最大距離,提供一遮罩20覆蓋該大型屏幕之外周緣,以覆蓋所有故障顯示單元,其中該遮罩之寬度D大於等於該最大距離;舉例來說,如圖4所示,所有橫列中,橫列Y51具有一個位於最遠離橫列Y51之該第二側1a外緣的故障顯示單元A4,故障顯示單元A4之右側與橫列Y51之該第二側1a外緣之間具有該最大距離,基於該最大距離,提供一遮罩20覆蓋該大型屏幕1之外周緣,以覆蓋所有故障顯示單元,如此一來,如圖5所示,當點亮該大型屏幕1使其工作顯示影像時,該大型屏幕1之外周緣將被該遮罩20遮蔽而能以平滑的狀態呈現,不會因為故障顯示單元的影響而呈現鋸齒狀,藉此以提供高品質的顯示畫面,增進觀賞者的觀影感受。In another embodiment, the step S08 may also be, based on the maximum distance, providing a mask 20 to cover the outer periphery of the large screen to cover all fault display units, wherein the width D of the mask is greater than or equal to the maximum distance; for example, as shown in FIG. 4 , among all the rows, row Y51 has a fault display unit A4 located at the outer edge of the second side 1a farthest from row Y51, and the right side of the fault display unit A4 is aligned with the second side 1a of row Y51. There is a maximum distance between the outer edges. Based on the maximum distance, a mask 20 is provided to cover the outer periphery of the large screen 1 to cover all faulty display units. In this way, as shown in FIG. 5 , when the large screen 1 is turned on to display images, the outer periphery of the large screen 1 will be shielded by the mask 20 and can be presented in a smooth state, and will not appear jagged due to the influence of the faulty display units, thereby providing a high-quality display image and enhancing the viewing experience of the audience.
又於另一實施例中,該步驟S08也可以是,該些橫列中至少一者的一側具有一個位於最遠離該橫列之該側外緣之故障顯示單元包含至少一故障之像素,該像素與該橫列之該側外緣間具有一最大距離,基於該最大距離定義一範圍,該範圍是自該陣列外緣徑向往內延伸大於或等於該最大距離之範圍,控制該範圍內覆蓋之所有顯示單元中之像素不顯示、顯示黑色或是被遮蔽。In another embodiment, the step S08 may also be that one side of at least one of the rows has a faulty display unit located farthest from the outer edge of the side of the row, including at least one faulty pixel, and there is a maximum distance between the pixel and the outer edge of the side of the row. A range is defined based on the maximum distance, and the range is a range extending inward from the outer edge of the array to a range greater than or equal to the maximum distance, and the pixels in all display units covered within the range are controlled not to display, to display black, or to be blocked.
如此一來,所有位於接近該陣列外圍之故障顯示單元中之故障像素皆位於該範圍中,當點亮該大型屏幕1使其工作顯示影像時,該範圍中之所有像素將以不顯示、顯示黑色或是被該遮罩20遮蔽的方式呈現,且最遠離該大型屏幕1外緣之故障單元中之部分正常像素能正常顯示,進而能達到以最大化的保持該大型屏幕1所呈現之畫面的完整性的目的,不會因為故障顯示單元的影響而呈現鋸齒狀,藉此以提供高品質的顯示畫面,增進觀賞者的觀影感受。In this way, all faulty pixels in the faulty display units located near the periphery of the array are located within the range. When the large screen 1 is turned on to display images, all pixels in the range will be displayed in a manner of not displaying, displaying black, or being shielded by the mask 20, and some normal pixels in the faulty units farthest from the outer edge of the large screen 1 can be displayed normally, thereby achieving the purpose of maximizing the integrity of the picture presented by the large screen 1, and it will not appear jagged due to the influence of the faulty display units, thereby providing a high-quality display picture and enhancing the audience's viewing experience.
綜上所述,本發明透過將故障顯示單元與設置於該陣列最接近外圍之正常顯示單元相互置換設置位置的方式,能將故障顯示單元先移置該大型屏幕之外緣,如此一來,能大幅降低故障顯示單元對整體畫面呈現之破壞以最大化的保持該大型屏幕1所呈現之畫面的完整性,進而能提供高品質的顯示畫面,除此之外,相較於習用檢修方法,為了呈現畫面完整性須快速將故障顯示單元檢修後安裝,本發明透過將故障顯示單元先移置該大型屏幕之外緣的方式,能改善當該陣列中故障顯示單元的數量過多時,備品不足以更換所有故障顯示單元的問題,使用者也不需於倉儲中囤積過多備品以備更換,進而能達到降低養護成本之目的,且維修人員也能在充裕的時間下針對故障顯示單元進行檢修,進而能達成減少維修人員之人數配置,以及降低維修人員工作負擔之效果。In summary, the present invention can move the faulty display unit to the outer edge of the large screen by replacing the faulty display unit with the normal display unit located closest to the periphery of the array. In this way, the damage caused by the faulty display unit to the overall image presentation can be greatly reduced to maximize the integrity of the image presented by the large screen 1, thereby providing a high-quality display image. In addition, compared with the conventional inspection method, in order to present the integrity of the image, the faulty display unit must be quickly inspected and replaced. The present invention can improve the problem of insufficient spare parts to replace all faulty display units when there are too many faulty display units in the array by first moving the faulty display units to the outer edge of the large screen. Users do not need to store too many spare parts in the warehouse for replacement, thereby achieving the purpose of reducing maintenance costs. Maintenance personnel can also inspect and repair the faulty display units in ample time, thereby achieving the effect of reducing the number of maintenance personnel and reducing the workload of maintenance personnel.
除此之外,透過該檢修方法檢修之該大型屏幕於播放影像時,該範圍中之所有顯示單元或是所有像素皆以不顯示、顯示黑色或是被遮蔽的方式呈現,能使得該大型屏幕顯示畫面之外緣,以平滑的狀態呈現,而不會受故障顯示單元的影響而呈現鋸齒狀,藉此以提供高品質的顯示畫面,增進觀賞者的觀影感受。In addition, when the large screen repaired by the inspection method plays images, all display units or all pixels in the range are displayed in a non-display, black or masked manner, so that the outer edge of the large screen display screen can be presented in a smooth state without being affected by the faulty display unit and appearing jagged, thereby providing a high-quality display screen and enhancing the viewer's viewing experience.
