Description of the Invention The present invention relates to a display method of a light-emitting display device using an organic EL device, and more particularly to a display method of a light-emitting display device featuring a control method of a pixel structure related. [Prior Art] In a flat-panel display device (flat display) such as an organic EL display, when the same still image is displayed for a long time, a phenomenon of "image sticking" occurs. The term "afterimage" as used herein means that only part of the display is degraded (lower luminance) to produce a visually identifiable residual image (rear image). The afterimage is likely to occur at the edge or the like of the still image. In an organic EL display having a plurality of sub-pixels having different emission wavelengths, there are many cases in which the degradation characteristics of each of the illumination colors are not completely identical. Further, since the contents of the images displayed on the display screen are not uniform, the degradation is apt to continue locally. In this case, since the degree of decrease in the luminance of each color is different, a so-called "color shift" in which the white balance is shifted occurs, thereby causing the white image to appear in color. Further, examples of the factors for accelerating the degradation include displaying a fixed pattern, inconsistent illumination time of each sub-pixel, time period of illumination, ambient temperature, and magnitude of luminance, which are the causes of the afterimage phenomenon. In order to suppress the image sticking phenomenon, it is preferred to increase the luminescence lifetime of the constituent material. However, it is difficult to say that the residual image can be sufficiently suppressed only by improving the material. The following description discloses a document for techniques for suppressing image sticking. First, Japanese Laid-Open Patent Publication No. 2000-356981 discloses a technique of controlling the luminance of each color based on the accumulated lighting time to ensure that the progress of degradation of each color is uniform, so that the afterimage is not made apparent. Secondly, the technique disclosed in Japanese Laid-Open Patent Publication No. 2001-175221 discloses the degradation of pixel brightness due to high-intensity illumination, and adjusts the brightness of other pixels to the brightness of the degraded pixel. Thus the afterimage is not obvious. However, according to the technique disclosed in Japanese Laid-Open Patent Publication No. 2000-3 5 698 1, only the brightness of the entire display screen is lowered according to the length of time displayed, and thus the "afterimage" phenomenon cannot be substantially avoided. occur. Further, since the brightness of the other pixels is adjusted to the brightness of the pixel degradation due to the high-intensity light emission, the technique disclosed in Japanese Patent Application Laid-Open No. Hei No. 200-175221, which is incorporated by reference, has the effect of suppressing the color shift. However, there is no effect of suppressing the degradation of brightness of the pixels themselves. In addition, additional sensors are required to detect brightness, resulting in increased manufacturing costs and reduced resolution. In the organic EL display, when the same still image is displayed for a long time, only a part of the display screen is degraded, thereby causing image sticking. Further, 'in the organic EL display having a plurality of sub-pixels of different light-emitting wavelengths', since the deterioration characteristics of each of the light-emitting colors are not uniform, this causes color shift in many cases. -5· 200926108 SUMMARY OF THE INVENTION The present invention has been accomplished in view of the above problems. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a display method of a light-emitting display device which can suppress image sticking of a pixel to enhance the life of the display panel. To achieve the above objects, the present invention includes the following specific features. The present invention provides a display method of a light-emitting display device including a display panel in which a plurality of images each having at least one sub-pixel are disposed. It is assumed that the coordinates are represented by "i" in the vertical direction and "j" in the horizontal direction. Thus, display of the image input material Da(i,j) constituting the pixel P(i,j) at the position (i,j) and having the sub-pixel Spa (i,j) of the display color "a" is implemented. There are two display methods in this case. The first display method implements display of the image input material Da (i, j) by using only the sub-pixel Spa (i, j). The second display method performs display of the image input material Da(i, j) by the nearby sub-pixel group Spa (the adjacent sub-pixel group Spa (i', j') each has a display color "a", and includes a sub-pixel group in which the V is placed in the vicinity of the pixel P(i', j') around the pixel P(i, j). In the light-emitting display device according to the present invention, the first display is combined. The second display method performs display control, and the combination between the two methods is changed in a controllable manner. In the display method of the light-emitting display device according to the present invention, the high resolution in the first display method is high. The long-life mode in which the ratio of the mode is higher than the second display method is switched so that the afterimage of the pixel can be suppressed to enhance the life of the display panel. From the following description of the exemplary embodiments with reference to the accompanying drawings, it will be clear -6- 200926108 Further Features of the Invention [Embodiment] Hereinafter, a display method of an illuminating display device according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings. Application According to an exemplary embodiment of the present invention Each of the illuminating display devices of the method includes a display panel in which a plurality of pixels each having at least one sub-pixel® are disposed. It is assumed that coordinates in the vertical direction are represented by "iv" and coordinates in the horizontal direction are It is represented by "j". Thus, the image input material Da (i J) is implemented corresponding to the sub-pixel Spa (i,j) constituting the pixel P(i,j) at the position (i,j) and having the display color "a" Display at this time. There are two display methods at this time. The first display method uses only the sub-pixel Spa (i, j) to display the image input data Da(i, j). The second display method is by using nearby The sub-pixel group Spa(i', j·) displays the image input data Da(i, j), and the nearby sub-pixel group Spa(i', j·) each has a display color ® "a" and is included in the configuration. a sub-pixel group in the vicinity of the pixel P(i,j). In the light-emitting display device according to the present invention, display control is implemented in combination with the first display method and the second display method, and both The combination between the two is changed in a controllable way. In addition, the first display in the display panel The combination ratio between the method and the second display method can be controlled to change for each image input material Da(i,j). (First Embodiment) Each of Figs. 1 to 15 illustrates the present invention. The pixel structure of the luminescence display device used in the first embodiment 200926108. Each of the illuminating display devices illustrated in Figures 1 to 9 displays the pixels 11 in a configuration of 3 columns by 3 rows (3x3). The red, green, and blue sub-pixels 11a, lib, and 11c are included. The coordinates in the vertical direction are represented by "i" and the coordinates in the horizontal direction are represented by "j,". The composition is located at the position (i The pixel P(i,j) at j) and the sub-pixel Spa (i,j) having the display color "a" implement display of the corresponding image input material Da(i,j). The term "sub-pixel Spa (i,j)" as used herein means, for example, a red sub-pixel, a green sub-pixel, or a blue sub-pixel constituting a pixel p (i, j). Further, the term "near pixel group P (i', j ·)," as used herein means, for example, a pixel P(il,j), P(i) surrounded by pixels P(i,j). + l,j) , P(i,jl), and P(i,j + 1). In addition, the term "near sub-pixel group Spa (i',j')" used in this article , meaning the nearby pixel groups P ( il,j ), P ( i+l,j ) , P ( i,jl ), and P ( i ) respectively included in the nearby pixel group P( i',j') , j + l ) a group of red sub-pixels, green sub-pixels, or blue sub-pixels of β. Figure 1 illustrates a high-resolution display mode in which only the first display method is used to display image input data Da(i, j) In the display mode illustrated in FIG. 1, each sub-pixel S pa ( i, j ) as a center of illumination emits light with a luminance of 1 〇〇%, and is only used as each of the illuminating centers. The pixel Spa ( i,j ) emits light so that sharp images with sharp outlines can be displayed. However, the high-density current is concentrated on a single pixel, which may cause image sticking due to degradation. Here, when the sub-pixel spaThe luminance of ( i J ) is shown by La ( i,j ) table 200926108, and its maximum luminance is represented by LaMAX ( i,j ) and its degree is (i,j) {0^c〇a(i, j) When $1} is expressed, the 'luminance luminance La(i,j) can be expressed by the equation (1) in the case where only the first display method is used for display: La(i,j) = Qa(i,j) χ LaMAx(i,j) *··(1) Figure 5 illustrates the longevity display mode in which only the second display method is used to 'display the image input data Da(i,j). In the display mode illustrated in Fig. 5, The pixel P ( i,j ) which is the center of illumination does not emit light, but is adjacent to each of the nearby pixels P(iU) , P(i+i,j) , P ( i,jl adjacent to the pixel P(u). And p ( U + l ) emit light with a brightness of 25%. In this display mode, the current density applied to the pixel P (i, j ) as the center of illumination is evenly distributed adjacent to the vicinity thereof Pixels P ( i-lj ) , p ( i + l, j ) , P ( i, jl ), and P ( i, j + l ), thus reducing the degradation of the pixel P ( i, j ). In the display mode illustrated in FIG. 5, since the luminance of the light is emitted by the pixel P (il,j) adjacent to the pixel P(i,j) , P ( i+l,j ) , P ( i,jl ), and P ( i,j + l ) are leveled by ®, so the boundary of the shape becomes smooth, and as a result, it is not easy to recognize the brightness The changes caused by degradation. That is, the image sticking of the display panel is suppressed by cooperating with the effect of reducing the effect of degradation and smoothing the boundary of the outline. Fig. 3 shows an intermediate mode between the high resolution mode and the long life mode, in which the 'image input data Da(i, j) is displayed by the combination of the first display method and the second display method with a combination ratio of 50%. In the day of the month @ display mode shown in Fig. 3, the pixel P (i, j) as the center of illumination emits light with a brightness of 5〇%, and adjacent pixels P(il,j), P(i) adjacent thereto + lj 200926108 ), P ( i,j -1 ) ' and P ( i,j + 1 ) emit light with a brightness of 1 2 · 5 %. In the display mode illustrated in FIG. 3, the luminance of the pixel P(i, j) is reduced to 50%' and corresponding to the reduced luminance thereof, is uniformly distributed to the adjacent pixel P adjacent thereto (il, j) ), P(i + l, j) , P(i, jl) , and + . Therefore, the afterimage is suppressed compared to the high resolution mode. However, the sharpness of the image is somewhat reduced. In the intermediate mode, the combination ratio between the first display method and the second display method is not limited to the ratio illustrated in Fig. 3, and can be adjusted as desired. The intermediate mode illustrated in Fig. 2 is a combination of the first display method and the second display method using the first display method at a ratio of 80% to display the image input material Da(i, j). The intermediate mode illustrated in Fig. 4 is a combination of the first display method and the second display method using a ratio of the first display method of 20% to display the image input material Da(i, j). The higher the ratio using the first display method, the sharper the sharper image. However, a larger current density is applied to the pixel P(i,j) as the center of luminescence so that image sticking tends to occur. Further, in the case where the resolution of the display panel is low, there is a possibility that the oblique line displayed thereon has a sawtooth or the like. Conversely, the lower the ratio of using the first display method, the longer the life of the display with a smoother outline and less degradation, but the entire image displayed is somewhat blurred. However, in the case of a low-resolution display panel, there is also an effect of smoothing the contour and increasing the resolution. When the display is performed in combination with the first display method and the second display method, it is necessary to satisfy the following formulas (2) and (3).

200926108 100 %的亮度來發光，以致於其必須修正發光亮度。修正發 光亮度之方法的例子如圖14之說明，其允許所有需要以 超過100%之亮度發光的像素以100%的亮度發光。當採用 此方法時，藉由修正而將亮度降至100%的像素以低於正 常亮度之亮度實施顯示。特別是，當使用第二顯示方法的 比例大時，亮度降低的缺點也跟著變大。 修正發光亮度之方法的另一例係將100%以上的額外 © 亮度分配給四周的像素。例如圖13之說明，假設第二顯 示方法對於位在位置（i，j)與+ 處且每一以100% 之亮度發光之像素中位在位置（i，j )處之像素僅施加40% 的比例。在此情況，各個像素P ( i，j -1 ) 、P ( i-1，j )、及 P ( i+l，j )以10%的亮度發光，且像素P ( i,j + l )需要以 110%的亮度發光。在此，像素？（丨，〗+ 1)的亮度超過 10 0%，以致於要做修正以將10%的額外亮度分配給四周的 像素。如圖15之說明，像素P ( i，j + l )之10%的額外亮 ® 度被配置給四周每一個像素各2.5%。在此情況中，像素P (i，j + l )以100%的亮度發光，且每一個像素P ( + l )、P ( i,j + 2 )、及 P ( i + l,j + l )以 2.5%的亮度發光。像 素P ( i,j )以62.5%的亮度發光。當使用此方法時，與上 述允許所有需要以超過100%之亮度發光的像素以100%之 亮度發光的修正方法相較，其可以顯示較銳利的影像，且 亮度下降較小。 還有另一發光亮度修正法的例子係以預定之低亮度來 發光的方法。在此方法中，事先將顯示面板的最大亮度設 -12- 200926108 定在一低値。因此，即使當亮度被分配時，也能防止像素 以高於100%的亮度發光。例如，如圖13之說明，當亮度 分配的結果是像素P(i，j + 1)需要以110%的亮度發光時 ，其需要做到滿足像素p ( i,j + l )以100%之亮度發光的 修正。換言之，例如藉由將初始亮度設定到大約9 0 %，即 使當實施此亮度分配時，也可避免亮度超過100%。此方 法可使用按照本發明的顯示方法來實施。不過，問題是顯 © 示面板其本身的亮度會降低。 按照本發明，藉由依據意欲之用途或環境，以可切換 的方法使用高解析模式、長壽模式、或中間模式，可減少 像素的殘影以增進顯示面板的壽命。 例如，以隨著像素之影像輸入資料Da ( i ,j )之空間 改變的增加，隨著像素之影像輸入資料Da(i，j)之時間 改變的縮短’或隨著像素之影像輸入資料Da(i，j)之發 光時間的增加而增加第二顯示方法的使用比例爲較佳。此 ® 外，對於每一子像素之第二顯示方法的組合比，隨著子像 素的退化率增加而增加，且對於每一子像素之第—顯示方 法的組合比，隨著子像素的退化率減小而增加爲較佳。此 外，較佳是隨著溫度之上升、隨著最大發光亮度之增加、 或隨著顯示時間之增加，也增加第二顯示方法的組合比。 亦即’對於影像輸入資料Da ( i, j )之空間改變較大 的像素’增加對應子像素Spa(i,j)之第二顯示方法的比 例。此外，對於影像輸入資料Da ( i,j )之時間改變較小 的像素’增加對應子像素Spa(i，j)之第二顯示方法的比 -13- 200926108 例。此外，對於影像輸入資料Da ( i，j )之發光時間較長 的像素，也增加第二顯示方法的比例。此外，在每一像素 包括兩或多個子像素的情況中，當一子像素的退化率高於 另一子像素的退化率時，增加該子像素之第二顯示方法的 組合比，而當一子像素的退化率低於另一子像素的退化率 時，增加該子像素之第一顯示方法的組合比。此外，關於 至少一個子像素之第一顯示方法與第二顯示方法之間的組 © 合比，隨著溫度的上升而增加第二顯示方法的組合比。此 外’關於至少一個子像素之第一顯示方法與第二顯示方法 之間的組合比，隨著最大發光亮度的增加而增加第二顯示 方法的組合比。此外，關於至少一個子像素之第一顯示方 法與第二顯示方法之間的組合比，隨著顯示時間的增加而 增加第二顯示方法的組合比。順帶一提，在至少一個子像 素中’第一顯示方法與第二顯示方法之間的組合比例如是 1:2° ® 特別說明’例如，當在高解析度顯示面板上顯示影像 時’或當顯示快速移動的影像時，以使用發光中心像素之 發光比爲100%的高解析模式爲較佳。當顯示固定圖案時 ’或當不需要高解析度時，以使用各個像素都分配到發光 比的長壽模式爲較佳，藉以抑制像素殘影。此外，在一般 操作中，以使用中間模式並依據意欲的用途或環境來切換 顯示模式爲較佳。 藉由不僅根據所要顯示的影像，還根據所累積的發光 量、溫度、或發光亮度之大小，在高解析模式、長壽模式 -14- 200926108 、及中間模式之間切換顯示模式，顯示面板的壽命可獲增 進。亦即，藉由依據影像輸入資料Da ( i，j )之空間改變 與時間改變、子像素的發光時間、退化率、溫度、發光亮 度、及顯示時間，在高解析模式、長壽模式、及中間模式 之間實施切換，顯示面板的壽命可獲增進。順帶一提，本 文中所使用之“累積的發光量”一詞，意指藉由沿著X軸取 發光時間及沿著y軸取發光亮度積分所獲得到的値。 在各個子像素的退化特性依照累積之發光量而改變的 情況中，藉由在退化率高之時域中增加第二顯示方法的比 例，顯示面板的壽命可獲增進。例如，退化率通常隨著累 積之發光量的增加而降低。因此，當累積之發光量小時， 在所施加的顯示模式中，發光中心像素的發光比低，而附 近像素的發光比高。隨著累積之發光量變得較大，顯示模 式切換到發光中心像素的發光比高，而附近像素之發光比 低的模式。因此，可長時間顯示高解析度的影像。 在各個子像素的退化特性依照環境溫度而改變的情況 中，當環境溫度變爲退化率高的溫度時，可將第二顯示方 法的比例設定到一較大的値，藉以增進顯示面板的壽命。 例如，像素的退化率通常隨著溫度上升而增加。因此，當 環境溫度低時，在所施加的顯示模式中，以發光中心像素 的發光比高而附近像素的發光比低爲較佳。當環境溫度上 升時，顯示模式以切換到發光中心像素的發光比低而附近 像素的發光比高爲較佳。 此外’在各個子像素的退化特性依照發光亮度之大小 200926108 而改變的情況中，藉由爲處於退化率高之發光亮度的像素 增加第二顯示方法的比例，顯示面板的壽命可獲增進。例 如，通常考慮當發光亮度高時，像素的退化率高。因此， 以發光中心像素的發光比高而附近像素的發光比低的顯示 模式施加於發光亮度低之影像輸入資料爲較佳。另一方面 ，以發光中心像素之發光比低而附近像素之發光比高的顯 示模式施加於發光亮度高的影像輸入資料爲較佳。 ® 接下來描述藉由控制第一顯示方法與第二顯示方法來 實施顯示的控制方法。 圖30的方塊圖說明按照本發明之實施例之發光顯示 設備的結構。如圖30所示，按照本發明之實施例之發光 顯示設備包括信號輸入部1、亮度分配單元2、A/D轉換 部3、及顯示部4。信號輸入部1接收影像信號。亮度分 配單元2對輸入到信號輸入部1的影像信號實施亮度分配 處理，並將經處理的信號輸出給A/D轉換部3。A/D轉換 ® 部3對從亮度分配單元2輸出的影像信號實施A/D轉換。 顯示部4根據從A/D轉換部3輸出的影像信號來顯示影像 〇 按照本發明之實施例的發光顯示設備，另包括用以偵 測環境溫度的熱偵測部5，用以獲得到顯示部4之發光亮 度的電流偵測部6，以及用以測量累積之發光時間的累積 發光時間測量部7。 亮度分配單元2係用來調整第一顯示方法與第二顯示 方法之間的比例，並依據所意欲的用途或環境，在高解析 -16- 200926108 模式、長壽模式、及中間模式之間選擇所想要之模式的轉 換部。 熱偵測部5係用來感測溫度及用來測量發光顯示設備 之溫度的感測器。當發光顯示設備的溫度到達退化率高的 溫度時，增加第二顯示方法的比例，以便抑制殘影。 電流偵測部6係用來測量發光顯示設備所消耗的電流 。藉由爲以高亮度發光之部分像素增加第二顯示方法的比 例’殘影可被抑制。累積發光時間測量部7測量累積的發 光時間。藉由對明顯退化部分中的像素應用第二顯示方法 ，殘影可被抑制。 (第二實施例） 接下來將描述本發明之第二實施例中所使用的發光顯 示設備。圖16至18的槪圖說明本發明之第二實施例中所 使用之發光顯示設備的像素結構。 圖16說明高解析顯示模式中的像素結構，其中僅以 第一顯示方法來顯示影像輸入資料Da(i，j)。該像素結 構具有3x3個像素11。每一個像素u分別包括紅、綠、 及藍色子像素11a、lib、及11c。在垂直方向中的座標以 “i”表示，及在水平方向中的座標以“j”表示。實施關於構 成位於位置（i，j )處之像素P ( i，j )且具有顯示色“a”之子 像素Spa ( i，j )之影像輸入資料Da ( i，j )的顯示。 在具有不同發光波長之複數個子像素彼此間退化特性 不一致的情況中’當包括在一像素中的紅、綠、及藍色子 -17- 200926108 像素被允許以固定的亮度發光時，退化率高之子像素與其 它退化率低之子像素的發光亮度終將彼此不同’以致發生 色偏。按照本實施例，藉由爲發光中心像素及附近像素的 各個子像素調整第一顯示方法與第二顯示方法之間的組合 比，由於退化所導致之顯示面板的色偏可被抑制。 在圖16所說明的高解析顯示模式中，包括在做爲發 光中心之像素P ( i，j )中之做爲紅、綠、及藍色子像素的 子像素8?3(1」），以100%的亮度均勻地發光，以致於可 顯示輪廓清晰的銳利影像。不過，當紅、綠、及藍各個顏 色的退化特性不同時，由於3個顏色的子像素都分別被允 許以1 00%的亮度發光而將發生由於亮度退化所導致的色 偏。 當假設像素P(i，j)之顯示色“a”的發光亮度以La( i，j)表不’其最大發光亮度以LaMAX ( i,j )表示，且其階 度以o>a(i,j)表示時，在僅使用第一顯示方法來顯示的情 ® 況中，發光亮度La(i，j)可藉由下式（4) 、（5) 、（6 )來表示： L (i，j) = cor(i,j) X I/max (i, j ) ...(4)LaU, force =®a(i, force x I (aa(i, j : i,,j·,,丨)),..(2) Jaa(i, J : = 1 ---(3) 'In the second display method, the pixels to which the light emission luminance is arranged are not limited to the nearby pixels P ( i -1 , j ) , p ( i + 1, j ) , P ( i, j -1 ), and • P ( U +1 ). For example, as shown in FIG. 6 'the luminance of the light is configurable to the pixels P ( ), P ( Φ i+l, jl ) , p ( + ) located at the oblique position of the pixel P ( i, j ) l), and p (i+l, j + l ) Further, in the second display method, as long as the above formulas (2) and (3) are satisfied, the position and number of pixels in which the light-emitting luminance is arranged are not limited. 7A, 7B, 8A, and 8B, the total number of pixels in which the light-emitting luminance is configured by the second display method is arbitrary, and as illustrated in FIG. 9, the brightness can be changed for each pixel in the second display method. Configuring the ratio. The pixels of the illuminating brightness are configured by the second display method, and those pixels are not limited to being arranged by 3 columns by 3 rows (3 X 3 ), or as illustrated in FIG. 1 , the pixels are multiplied by 5 columns. Lines (5x5) are arranged, or as illustrated in Figure 11, those pixels are triangular When the display is implemented in combination with the first display method and the second display method, there is a case where a pixel is required to emit light with a luminance greater than 100%. For example, FIG. 12 illustrates 3x4 pixels and is located at a position (i) , j ) pixels and pixels at position (i, j + l), each emitting with 100% brightness. As illustrated in Figure 13, when only 40 is applied to pixels at position (i, j) In the second display method of the ratio of %, each pixel p ( i,j_i ), P ( il,j ), and P ( i+l,j ) emits light with a luminance of 10%, and P ( Μ + 1) The brightness needs to be illuminated. However, the pixel cannot emit light with a brightness exceeding -11 - 200926108 100%, so that it must correct the brightness of the light. An example of a method of correcting the brightness of the light is illustrated in Figure 14, which allows all needs to be exceeded. 100% of the luminance-emitting pixels emit light at 100% brightness. When this method is used, the pixels whose brightness is reduced to 100% by correction are displayed at a brightness lower than the normal brightness. In particular, when the second display is used When the proportion of the method is large, the disadvantage of brightness reduction is also changed. Another example of the method of correcting the brightness of the light is to assign more than 100% of the additional brightness to the surrounding pixels. For example, as illustrated in Fig. 13, it is assumed that the second display method is at the position (i, j) and + and each A pixel that emits light at 100% brightness has a 40% ratio of pixels at the position (i, j). In this case, each pixel P ( i,j -1 ) , P ( i-1,j ), and P ( i+l,j ) emit light with a luminance of 10%, and the pixel P ( i,j + l ) It needs to emit light at 110% brightness. Here, the pixel? The brightness of (丨, 〗 + 1) exceeds 10 0%, so that corrections are made to assign 10% of the extra brightness to the surrounding pixels. As illustrated in Figure 15, an additional 10 degrees of brightness for the pixel P (i, j + l ) is configured to 2.5% each of the surrounding pixels. In this case, the pixel P (i, j + l ) emits light with 100% brightness, and each pixel P ( + l ), P ( i, j + 2 ), and P ( i + l, j + l ) emits light at a brightness of 2.5%. The pixel P (i, j) emits light at a luminance of 62.5%. When this method is used, it can display a sharper image with less sharpness reduction than the above-described correction method that allows all pixels that need to emit light with a luminance of more than 100% to emit light at 100%. Still another example of the illumination luminance correction method is a method of emitting light with a predetermined low luminance. In this method, the maximum brightness of the display panel is set to -12-200926108 in advance. Therefore, even when the luminance is assigned, the pixel can be prevented from emitting light with a luminance higher than 100%. For example, as illustrated in FIG. 13, when the result of the luminance distribution is that the pixel P(i, j + 1) needs to emit light with a luminance of 110%, it needs to satisfy the pixel p (i, j + l ) by 100%. Correction of brightness illumination. In other words, for example, by setting the initial luminance to about 90%, even when this luminance distribution is implemented, the luminance can be prevented from exceeding 100%. This method can be carried out using the display method according to the present invention. However, the problem is that the brightness of the display panel itself will decrease. According to the present invention, by using a high resolution mode, a long life mode, or an intermediate mode in a switchable manner depending on the intended use or environment, the image sticking of the pixels can be reduced to enhance the life of the display panel. For example, with the increase of the spatial change of the image input data Da (i, j) with the pixel, the time change of the image input data Da(i, j) of the pixel is shortened' or the image is input with the image of the pixel Da It is preferable to increase the light-emitting time of (i, j) and increase the use ratio of the second display method. In addition to this, the combination ratio of the second display method for each sub-pixel increases as the degradation rate of the sub-pixel increases, and the combination ratio of the first-display method for each sub-pixel decreases with the sub-pixel The rate is reduced and the increase is preferred. Further, it is preferable to increase the combination ratio of the second display method as the temperature rises, as the maximum luminance is increased, or as the display time increases. That is, the ratio of the second display method of the sub-pixel Spa(i, j) is increased by the pixel 'with a large spatial change in the image input data Da (i, j). Further, the pixel 'with a small change in the time of the image input data Da (i, j ) is increased by the ratio of the second display method of the sub-pixel Spa(i, j) -13-200926108. In addition, the ratio of the second display method is also increased for pixels in which the image input data Da (i, j ) has a long light-emitting time. In addition, in the case where each pixel includes two or more sub-pixels, when the degradation rate of one sub-pixel is higher than the degradation rate of the other sub-pixel, the combination ratio of the second display method of the sub-pixel is increased, and when When the degradation rate of the sub-pixel is lower than the degradation rate of the other sub-pixel, the combination ratio of the first display method of the sub-pixel is increased. Further, the combination ratio of the first display method and the second display method of the at least one sub-pixel increases the combination ratio of the second display method as the temperature rises. Further, the combination ratio between the first display method and the second display method with respect to at least one sub-pixel increases the combination ratio of the second display method as the maximum light-emitting luminance increases. Further, with respect to the combination ratio between the first display method and the second display method of at least one sub-pixel, the combination ratio of the second display method is increased as the display time is increased. Incidentally, in the at least one sub-pixel, the combination ratio between the first display method and the second display method is, for example, 1:2° ® special description 'for example, when displaying an image on a high-resolution display panel' or when When displaying a fast moving image, it is preferable to use a high resolution mode in which the light emission ratio of the light emitting center pixel is 100%. When a fixed pattern is displayed ‘or when high resolution is not required, it is preferable to use a long life mode in which each pixel is assigned to a light-emitting ratio, thereby suppressing pixel sticking. Further, in normal operation, it is preferable to switch the display mode by using the intermediate mode and depending on the intended use or environment. The display panel is switched between the high resolution mode, the long life mode-14-200926108, and the intermediate mode according to not only the image to be displayed but also the accumulated amount of light, temperature, or brightness of the light. Can be improved. That is, in the high-resolution mode, the long-life mode, and the middle by the spatial change and time change according to the image input data Da (i, j ), the light-emitting time of the sub-pixel, the degradation rate, the temperature, the light-emitting brightness, and the display time. Switching between modes allows the life of the display panel to be improved. Incidentally, the term "cumulative illuminance" as used herein means the enthalpy obtained by taking the illuminating time along the X axis and the illuminating brightness integral along the y axis. In the case where the degradation characteristics of the respective sub-pixels are changed in accordance with the accumulated luminescence amount, the life of the display panel can be improved by increasing the ratio of the second display method in the time domain where the degradation rate is high. For example, the degradation rate generally decreases as the amount of accumulated luminescence increases. Therefore, when the accumulated luminescence amount is small, in the applied display mode, the luminescence ratio of the luminescence center pixel is low, and the luminescence ratio of the nearby pixel is high. As the accumulated amount of luminescence becomes larger, the display mode is switched to a mode in which the illuminance ratio of the illuminating center pixel is high and the illuminance ratio of the nearby pixels is low. Therefore, a high-resolution image can be displayed for a long time. In the case where the degradation characteristics of the respective sub-pixels change according to the ambient temperature, when the ambient temperature becomes a temperature at which the degradation rate is high, the ratio of the second display method can be set to a larger 値, thereby enhancing the life of the display panel. . For example, the degradation rate of a pixel generally increases as the temperature rises. Therefore, when the ambient temperature is low, in the applied display mode, it is preferable that the light-emitting ratio of the light-emitting center pixel is high and the light-emitting ratio of the nearby pixels is low. When the ambient temperature rises, the display mode is preferably such that the light-emitting ratio of the pixels switched to the center of the light is low and the light-emitting ratio of the nearby pixels is high. Further, in the case where the degradation characteristic of each sub-pixel is changed in accordance with the magnitude of the luminance of the luminance 200926108, the lifetime of the display panel can be improved by increasing the ratio of the second display method for the pixel having the luminance of the luminance having a high degradation rate. For example, it is generally considered that when the luminance of the light is high, the degradation rate of the pixel is high. Therefore, it is preferable to apply a display mode in which the light-emitting ratio of the light-emitting center pixel is high and the light-emitting ratio of the nearby pixels is low to the image input data having a low light-emitting luminance. On the other hand, it is preferable to apply a display mode in which the light-emitting ratio of the light-emitting center pixel is low and the light-emitting ratio of the nearby pixels is high to the image input data having a high light-emitting luminance. ® Next, a control method for performing display by controlling the first display method and the second display method will be described. Figure 30 is a block diagram showing the construction of an illuminating display device in accordance with an embodiment of the present invention. As shown in Fig. 30, a light-emitting display device according to an embodiment of the present invention includes a signal input unit 1, a brightness distribution unit 2, an A/D conversion unit 3, and a display unit 4. The signal input unit 1 receives an image signal. The brightness distribution unit 2 performs brightness distribution processing on the video signal input to the signal input unit 1, and outputs the processed signal to the A/D conversion unit 3. The A/D conversion section 3 performs A/D conversion on the video signal output from the luminance distribution unit 2. The display unit 4 displays an image according to the image signal output from the A/D conversion unit 3, and the light-emitting display device according to the embodiment of the present invention further includes a heat detecting portion 5 for detecting the ambient temperature for obtaining the display. The current detecting portion 6 of the light-emitting luminance of the portion 4, and the cumulative light-emitting time measuring portion 7 for measuring the accumulated light-emitting time. The brightness distribution unit 2 is configured to adjust the ratio between the first display method and the second display method, and select between the high resolution-16-200926108 mode, the longevity mode, and the intermediate mode according to the intended use or environment. The conversion part of the desired mode. The heat detecting portion 5 is a sensor for sensing temperature and for measuring the temperature of the light-emitting display device. When the temperature of the light-emitting display device reaches a temperature at which the degradation rate is high, the ratio of the second display method is increased to suppress image sticking. The current detecting unit 6 is for measuring the current consumed by the light-emitting display device. The residual image can be suppressed by increasing the ratio of the second display method for a portion of the pixels that emit light with high luminance. The cumulative lighting time measuring section 7 measures the accumulated lighting time. By applying a second display method to pixels in the significantly degraded portion, the afterimage can be suppressed. (Second Embodiment) Next, a light-emitting display device used in the second embodiment of the present invention will be described. 16 to 18 are views showing the pixel structure of the light-emitting display device used in the second embodiment of the present invention. Fig. 16 illustrates a pixel structure in the high resolution display mode in which the image input material Da(i, j) is displayed only in the first display method. This pixel structure has 3 x 3 pixels 11. Each of the pixels u includes red, green, and blue sub-pixels 11a, lib, and 11c, respectively. The coordinates in the vertical direction are indicated by "i", and the coordinates in the horizontal direction are indicated by "j". A display is performed on the image input material Da(i,j) constituting the sub-pixel Spa (i,j) of the pixel P(i,j) located at the position (i,j) and having the display color "a". In the case where a plurality of sub-pixels having different illuminating wavelengths do not have degenerate characteristics with each other, 'when the red, green, and blue sub--17-200926108 pixels included in one pixel are allowed to emit light at a fixed luminance, the degradation rate is high. The luminances of the sub-pixels and the sub-pixels having other degradation rates will eventually be different from each other' such that color shift occurs. According to this embodiment, by adjusting the combination ratio between the first display method and the second display method for each of the sub-pixels of the illuminating center pixel and the nearby pixels, the color shift of the display panel due to the degradation can be suppressed. In the high-resolution display mode illustrated in FIG. 16, the sub-pixels 8?3(1") which are red, green, and blue sub-pixels in the pixel P(i,j) as the light-emitting center are included, It emits light uniformly with 100% brightness, so that sharp images with sharp outlines can be displayed. However, when the degradation characteristics of the respective colors of red, green, and blue are different, since the sub-pixels of the three colors are respectively allowed to emit light at a luminance of 100%, a color shift due to luminance degradation occurs. When it is assumed that the luminance of the display color "a" of the pixel P(i,j) is represented by La(i,j), its maximum luminance is represented by LaMAX(i,j), and its gradation is o>a( When i, j) is expressed, in the case of displaying using only the first display method, the light-emitting luminance La(i, j) can be expressed by the following formulas (4), (5), (6): L (i,j) = cor(i,j) XI/max (i, j ) ...(4)

As illustrated in FIG. 18, the red sub-pixel Sp^CU in the pixel p(i,j) as the illuminating center and the green sub-pixel Spg(i,j)-18-200926108 each have a brightness of 100%. Light is emitted, and the blue sub-pixel Spb (iJ) included therein does not emit light. Instead, they are respectively included in the neighboring pixels P ( il,j ), P ( i+l,j ) , P ( i,jl ), and P ( i,j + l ) adjacent to the pixel P (U ). Each of the sub-pixels SPb ( il,j ), Spb ( i+l,j ) , Spb ( i,jl ), and Spb ( i,j + l ) emits light at a luminance of 25%. For blue sub-pixels only, the luminance of the illumination is assigned to nearby pixels. Therefore, the current density applied to the blue sub-pixel Spb (i, j ) can be leveled, thereby suppressing ® degradation. This display mode is effective in the case where the degradation rate of the blue sub-pixel is particularly high than that of the other red and green sub-pixels. By making the degradation rate of the blue sub-pixel close to the degradation rate of the other red and green sub-pixels, the effect of suppressing the color shift due to the afterimage can be obtained. Fig. 17 illustrates the pixel structure of the intermediate mode in which only the blue sub-pixel displays the image input material Da(i, j) at a combination ratio of 50% using the first display method and the second display method. As illustrated in FIG. 17, the red sub-pixel Spr (V) and the green sub-pixel Spg (i, j) included in the pixel P (i, j) as the illuminating center each emit light at 100%, and only include The blue sub-pixel Spb(i, j) therein emits light with a luminance of 50%. In this case, respectively included in the neighboring pixels P ( il,j ) , P ( i+l,j ) , P (with "), and p ( iJ + 1 ) adjacent to the pixel P ( i,j ) Each of the blue sub-pixels SpbCi-ij), Spb(i + 1J) )' Spb (i, j + l ) emits light at a luminance of 12.5%. The luminance of the blue sub-pixel Spb (i, j) is reduced by 50%, and the reduced luminance is equally distributed to the adjacent sub-pixels Spb(il,j), SPb(i+l,j), Spb adjacent thereto ( i, jl ), Spb ( i, j + 1 ). Therefore, the -19-200926108 afterimage is suppressed compared to the high resolution mode. However, the sharpness of the image is reduced. This display mode is effective in the case where the degradation rate of the blue sub-pixel is particularly high than that of the other red and green sub-pixels. By making the degradation rate of the blue sub-pixel close to the degradation rate of the other red and green sub-pixels, the color shift due to the residual image can be suppressed. When displayed in combination with the first display method and the second display method on the sub-pixel having the display color "a", the luminance L (i,j) needs to satisfy the following equations (7), (8), (9). ), (10), (11), and (12). Here, the luminance of the display color "a" of the pixel P(i,j) is represented by La(), and its maximum luminance is represented by LaMAX (i,j), and its gradation is (〇a (i,j) Representation, and aa (i,j) represents the luminance configuration ratio of the pixel p ( i,j ) to the nearby pixels.

However, the illuminance is adjusted by the degradation characteristics of red, green, and blue to avoid the ratio between the first display method and the second display method in the white balance shift intermediate mode is not limited to the 値 illustrated in FIG. And the appropriate ratio is selected according to the degradation characteristics of the sub-pixels of the color or according to the environmental conditions, for example, 'when the fixed pattern is to be displayed, it is preferable to increase the ratio of the second display, and in the second display method, The luminance of the high degradation rate is dispersed. Further, when the color between red, green, and blue color and white (hereinafter referred to as "intermediate color") is to be displayed, the influence of the color shift caused by the degradation of the sub-pixel is remarkable. Therefore, when the intermediate color is shown, it is preferable to increase the ratio of the second display method. Further, the second display method is not limited to a single color sub-pixel or may be applied to two or more color sub-pixels. For example, when the display order of the degradation rate, green, and blue (highest) is increased, the display blue is displayed by the second display method, and the green display is applicable to the intermediate mode between the first display method and the first display method, and the display is red. The first display can be applied to make the degradation rates of the colors consistent with each other, so as to suppress the life of the color-shifted display panel, not only by changing the ratio of the first display method and the second display method depending on the image to be displayed. The increase can also be enhanced by a large switching display mode based on the accumulated amount of luminescence, temperature, and illuminance. In the case where the degraded characteristic of each sub-pixel is in accordance with the accumulated amount of luminescence, 'by the time-dependent combination of the second display method in the time domain where the degradation rate is high, according to the preferred method sub-images, Obvious, and according to the red can be adapted to the two methods to improve, the small proportion of the situation - 21 - 26,2688 'color shift can be suppressed. For example, when the accumulated amount of luminescence is small, the degradation rate of the blue sub-pixel is higher than that of the other color. When the accumulated amount of luminescence is large, the degradation rate of the red sub-pixel is higher than that of the other color. Therefore, in order to suppress the color shift of the device, when the accumulated amount of light emission is small, a display mode having a higher ratio of the second display method is applied to the sub-pixel B. As the cumulative amount of luminescence increases, the ratio of the second display method can be increased for the red sub-pixels, thereby suppressing the color shift due to luminance degradation.

當每一子像素的退化特性依照環境溫度而變時，藉由 增加由於環境溫度導致退化率高之子像素之第二顯示方法 的比例，由於亮度退化所導致的色偏可獲抑制。例如，假 設在高溫環境中，紅色子像素的退化率高於其它色子像素 ，且在低溫環境中，藍色子像素的退化率高於其它色子像 素的情況。在此情況中，在高溫環境中，紅色子像素使用 第二顯示方法之比例高的顯示模式，且在低溫環境中，藍 色子像素使用第二顯示方法之比例高的顯示模式，藉以抑 制由於亮度退化所導致的色偏》 當每一子像素的退化特性依照發光亮度之大小而變時 藉由增加由於高發光亮度導致退化率高之子像素之第二 顯示方法的比例，由於亮度退化所導致的色偏可獲抑制。 例如，假設在高亮度發光中，紅色子像素的退化率高，而 在低亮度發光中，藍色子像素之退化率高的情況。在此情 況中，在以高亮度發光之時，紅色子像素使用第二顯示方 法之比例高的顯示模式，且在以低亮度發光之時，藍色子 像素使用第二顯示方法之比例高的顯示模式，藉以抑制由 -22- 200926108 於亮度退化所導致的色偏。 按照本發明的顯示方法’藉由每個子像素各自獨立地 應用尚解析模式、長壽模式、或中間模式，由於與紅、綠 、與藍之各個顏色相關之退化特性所導致的色偏被抑制。 例如’在藍色子像素之退化率明顯高於紅色與綠色子像素 的情況中，藉由僅對藍色子像素應用長壽模式，並對紅色 與綠色子像素應用一般的高解析模式，即可實現沒有色偏 ® 的長壽顯不面板。 (本顯示方法應用於實際設備的特例） 接下來描述按照本發明實施例之發光顯示設備的顯示 方法應用於實際設備的特例。圖19至22的情況是按照本 發明實施例之發光顯示設備的顯示方法應用於實際設備的 亮度退化曲線。 圖19係說明在紅、綠、與藍色子像素都被點亮以顯 灣 示白色的情況中，以與時間相依的正常化亮度來表示每一 顏色之正常化退化時間資料的例示性曲線。如圖1 9之說 明，當假定當毗鄰像素間的亮度差超過1 0%時將導致殘影 ，紅色在經過4 5小時後，綠色在經過2 8小時後，藍色在 經過5小時後，殘影可被識別。當所有子像素都僅以第一 顯示方法點亮時，藍色子像素在經過5小時後造成殘影， 而綠色子像素在經過28小時後造成殘影，以致於在顯示 面板中發生色偏。在此情況中，顯示面板的壽命爲藍色子 像素之殘影被辨識出之5小時的時間周期。 -23- 200926108 因此，使用及調整第一顯示方法與第二顯示方法結合 的顯示模式，使得各個顏色之子像素的退化率彼此間一致When the degradation characteristic of each sub-pixel is changed in accordance with the ambient temperature, the color shift due to the luminance degradation can be suppressed by increasing the proportion of the second display method of the sub-pixel having a high degradation rate due to the environmental temperature. For example, it is assumed that in a high temperature environment, the degradation rate of the red sub-pixel is higher than that of the other color sub-pixels, and in the low-temperature environment, the degradation rate of the blue sub-pixel is higher than that of the other color sub-pixels. In this case, in a high temperature environment, the red sub-pixel uses a display mode with a high ratio of the second display method, and in a low temperature environment, the blue sub-pixel uses a display mode with a high ratio of the second display method, thereby suppressing Color shift caused by luminance degradation" When the degradation characteristic of each sub-pixel is changed according to the magnitude of the light-emitting luminance, the ratio of the second display method of the sub-pixel having a high degradation rate due to high luminance is increased due to luminance degradation The color shift can be suppressed. For example, it is assumed that in the high-intensity light emission, the degradation rate of the red sub-pixel is high, and in the low-luminance light emission, the degradation rate of the blue sub-pixel is high. In this case, when the light is emitted with high luminance, the red sub-pixel uses a display mode in which the ratio of the second display method is high, and when the light is emitted at low luminance, the proportion of the blue sub-pixel using the second display method is high. The display mode is used to suppress the color shift caused by the brightness degradation by -22-200926108. According to the display method of the present invention, by applying the still analysis mode, the long life mode, or the intermediate mode independently for each sub-pixel, the color shift due to the deterioration characteristics associated with the respective colors of red, green, and blue is suppressed. For example, in the case where the degradation rate of the blue sub-pixel is significantly higher than that of the red and green sub-pixels, by applying the long-life mode only to the blue sub-pixel and applying the general high-resolution mode to the red and green sub-pixels, A long-life display panel without color shifting ® is achieved. (Special example in which the present display method is applied to an actual device) Next, a specific example in which the display method of the light-emitting display device according to the embodiment of the present invention is applied to an actual device will be described. The case of Figs. 19 to 22 is a luminance degradation curve applied to the actual device by the display method of the light-emitting display device according to the embodiment of the present invention. Figure 19 is a diagram showing an exemplary curve showing the normalized degradation time data of each color in the case where the red, green, and blue sub-pixels are all illuminated to show white. . As illustrated in Fig. 19, it is assumed that when the luminance difference between adjacent pixels exceeds 10%, the image sticking will be caused, after the red color is passed for 45 hours, the green color is after 28 hours, and after the blue color is passed for 5 hours. The afterimage can be identified. When all the sub-pixels are illuminated only by the first display method, the blue sub-pixels cause image sticking after 5 hours, and the green sub-pixels cause image sticking after 28 hours, so that color shift occurs in the display panel. . In this case, the life of the display panel is a period of 5 hours in which the afterimage of the blue sub-pixel is recognized. -23- 200926108 Therefore, the display mode combined with the first display method and the second display method is used and adjusted so that the degradation rates of the sub-pixels of the respective colors are consistent with each other.

Assumption. The following formula (13) represents an experimental model in which the device degrades with a power density of 1.5. In the formula, 1:1 and 1:2 each represent a degradation time, Ιι and 12 each represent a current density, and 1^ and L2 each represent a luminance. Further, although it is assumed that the current density and the light-emitting luminance are substantially proportional to each other, it is preferable to obtain it from the I-L characteristic. £l = main, 1.5 \^2 J \L2j Fig. 23 illustrates a pixel structure in the case where the display method of the light-emitting display device according to the embodiment of the present invention is applied to an actual device. In the example illustrated in Fig. 23, the red sub-pixel Spr(i,j) included in the pixel p(i j ) as the illuminating center is allowed to emit light in the first display method. Further, the green sub-pixel Spg(i, j) is allowed to emit light in a first display method with a ratio of 7〇% and a first display method with a ratio of 30%. Further, the blue sub-pixel Spb (i, j) is allowed to emit light in a first display method of a ratio of 2% and a first display method of a ratio of 80%. That is, in the example illustrated in FIG. 23, the red sub-pixel Spr (i, j) included in the pixel p (i, j) as the light-emitting center emits light with a luminance of 100%, and the green sub-pixel Spg (^ ) at 70°/. The luminance illuminating 'blue sub-pixel Spb (i, j) illuminates with a brightness of -2 - 200926108. Are included in adjacent pixels adjacent to pixel P(i,j)? (b, i, l, j), P (i, jl), and p (i, j + l) each of the green sub-pixels Spg (il, j), Spg (i + l, j), Spg(i, j-1), and Spg (1, 』+ 1) emit light with a brightness of 7.5%. Further, each of the blue sub-pixels 3?15 (i-l,j), Spb(i+l,j)> Spb(i,j-l), and Spb(i,j+1) emits light with a luminance of 20%. The luminance of each of the blue and edge sub-pixels included in the pixel p(i, j) as the center of illumination is distributed to the surrounding sub-pixels around, thereby suppressing degradation. Degradation of blue sub-pixels with a high degree of luminance distribution is further suppressed. 2 is a second display method in which the binding ratio is 30% in the green sub-pixel, and in the case of the second display method in which the blue sub-pixel is combined in a ratio of 80%, 'in terms of time-dependent normalized brightness The brightness degradation curve for each color. When white is displayed by using this display method, the red sub-pixels cause afterimages after 48 hours, and the green sub-pixels cause afterimages after 47 hours. The blue sub-pixels cause afterimages after 50 hours. In this display mode, all of the red 'green and blue sub-pixels have substantially the same de-retarding time, so that it is difficult to cause color shift due to luminance degradation while performing white display. Fig. 21 shows the normalized degradation time data of each color in a time-dependent normalized brightness in a case where white is displayed in an environment of 25 ° C and 60 ° C. When it is assumed that when the luminance difference between adjacent pixels exceeds 1 〇%, the afterimage will be caused, after 3 hours in the environment of 25 ° C and 3 hours in the environment of 60 ° C, the afterimage Will be recognized. Therefore, the display of the combination of the first display method and the second display method -25-200926108 mode is used and adjusted so that degradation in a 60 ° C environment with a high degradation rate is suppressed. Fig. 22 is a graph showing the luminance degradation curve of each color in a time-dependent normalized luminance in the case where the second display method is combined at a ratio of 80% in an environment of 60 °C. In this display mode, the pixel as the center of illumination emits light with a brightness of 20%, and the remaining 80% of the brightness is distributed (configured) to pixels near the periphery of the center pixel of the light. When white is displayed by using this display method, the time during which image sticking occurs in an environment of 60 ° C is extended to 40 hours. Therefore, in the case where the ambient temperature is high, the life of the display panel can be extended by applying the display mode in which the second display method of a high ratio is combined. (Specific effects of the present invention) Next, the effects of the display method of the light-emitting display device according to the embodiment of the present invention will be described in detail. 24 to 29 illustrate a pixel structure which specifically describes the effect of the display method of the light-emitting display device according to the embodiment of the present invention. Figure 24 illustrates 3x3 pixels. The coordinates in the vertical direction are denoted by "i" and the coordinates in the horizontal direction are denoted by "j". It is assumed that the pixel P(i, j) located at the position (i, j) is lit for 1 hour using the first display method. The luminance of the pixel P (i,j) before being illuminated for 100 hours is indicated by 1, and the luminance after being illuminated for 100 hours is represented by 1_α, where α(〇<α<1) represents the luminance degradation rate. As illustrated in FIG. 25, after the pixel P(i,j) is lit for 100 hours 'when all the pixels are allowed to uniformly emit light, the brightness L(i,j) of the pixel -26-200926108 P(i,j) ) is l-α, and the luminances L(i±l,j) and L(i,j±l) of the pixels P(i: bl,j ) and P(i,j±l) near the periphery are 1. Therefore, when the brightness ratio at which the residual image can be recognized is expressed as "X" (afterimage recognition luminance ratio), the condition that the image sticking cannot be recognized when all the pixels emit light can be obtained by the following equations (14) and (15). To represent. Therefore, in the case where only the first display method is used for display, the deterioration due to the afterimage is recognized when the luminance degradation rate becomes higher than the afterimage recognition luminance ratio "X". ^ = 1-(1-α) = α ·· (14) (15) In this case, the second display method is applied, and the pixel p(i,j) is lit for 100 hours. Fig. 26 illustrates a display mode used by the pixel P (i, j ) where the first display method is combined in a ratio of 1 - 4 s and the second display method is combined in a ratio of 4 s. That is, the pixels are illuminated for 100 hours in this display mode, wherein the luminance 'applied to the pixel p(i, )) is partially allocated to each nearby pixel p(i+1, in a ratio of s. j) Φ , P(i, j + l), and . It is assumed that after the pixels are lit for 1 hour in this display mode, as shown in Fig. 27, all the pixels are allowed to uniformly emit light. In this case, the luminance L ( i, j) of the pixel p (i, j) is i_a (b "). The nearby pixels p ( i + 1, j ), P (il, j), P (i, j) + l), and PGj") The brightness L ( i + l, j ) , L ( il, j ) , L ( υ + 1 ), and L ( Μ ") are ^ sa. The luminance L ( i+l,j + i ), L ( ), L(i_l, J + of each pixel P(i+1, j + 1), p(i+lj l) + ' and P ( ) l), and [(丨-丨小丨) is }, therefore, when the resolution of the residual image is assumed to be represented by x, it is impossible to recognize the residual image at the time of illumination of all the pixels -27-200926108 The condition can be expressed by the following formulas (16), (17), and (18). Δι = 1-sa- (1-a(l-4s)) = a{l-5s) .-.(16) §2 = 1~ (1-soc) = sa · · - (17) δι^χ Δ2^χ . . - (18) ' As can be seen from the above equations (16), (17), and (18), when δρδ;^, the ratio at which degradation is extremely difficult to be recognized is obtained, that is, s = 1 / 6. Therefore, its 0 can be regarded as a display mode in which degradation is extremely difficult to be recognized when the entire surface is illuminated. The ratio between the first display method and the second display method is 1:2. Further, the brightness degradation rate a and the afterimage recognition luminance ratio X have the relationship expressed by the following formula (19). Oc<6x · · · (19) Therefore, if the ratio of the second display method is increased, when the brightness degradation rate a is greater than 6 times the afterimage recognition luminance ratio X, the degradation will be recognized. Fig. 28 illustrates the pixel structure in the case where the coordinates in the vertical direction are represented by "i", the coordinates in the horizontal direction © the direction are indicated by "j", and the pixels at the position jhi are lit for 100 hours. Suppose that the brightness of each pixel before the pixel is lit 1 hour ago is 1, and it is assumed that the brightness of the pixel P (i,j ) { ]>〇〇!} after the pixels are lit for 100 hours is Ι -a. Here, a ( 〇 < α < 1) indicates the luminance degradation rate. As illustrated in FIG. 29, after lighting for 100 hours, the pixels of the region {i^G) 2} are allowed to be combined in the ratio of 1 - 4 s in the first display method and 4 s in the ratio of the second display method. Illuminated in the mode. That is, the pixels which are the center of the illuminating light are emitted at a ratio of 1 - 4 s, and are arranged (or distributed) at a current density of a ratio of s to the respective nearby pixels at the upper, lower, right, and left positions. In this case, the current density is allocated to the ratio of -28-200926108 1 to the pixel of i<to2 in the light-emitting area, and is allocated to the ratio of l_s to the pixel of i = (02, and is arranged in the ratio of S to be adjacent to i = (pixels of i = c〇2 + l of pixels of 〇2. The pixels of i^c〇2 + 2 outside the pixel of i = t〇2 + l, that is, the 'outside of the light-emitting area is not allowed to emit light. Therefore, the brightness of each pixel can be expressed by the following equations (20), (21), (22), (23), (24), and (25). ❹ L (i, j ) {i=co2 +l, j%} = s ...(20) L (i^ j ) {ϊ=ω2+1, = s (1-a) ...(21) L (i, j ) {ϊ=ω2 , j<Qi} = 1-s -.-(22) L (i, j ) {ΐ=ω2, j^Qi) = (1-s) (1-a) ...(23) L (i , j ) {i<&)2, j<c〇i} = 1 .--(24) L (i, j ) {ί<ω2, j^i} = 1-a ..-(25) Here, the condition that the image is not recognized by the pixel that has been lit for 1 hour and other pixels is represented by the following equations (26), (27), (28), and (29). Further, the condition in which the uniform light-emitting region can be seen by applying the second display method is expressed by the following equations (30), (31), and (32). According to equations (26), (27), (28) ' and (29) •, the current density configuration (or distribution) ratio s is 0 < s < 1/4. Therefore, the condition that the image is not recognized between the degraded pixel and the undegraded pixel is aU. Further, by applying the second display method, it can be seen that the condition of the region where the light emission is uniform is s^x.
