Description
本發明係關於一種顯示方法，特別是關於一種可降低邊緣波紋的顯示方法。The present invention relates to a display method, and more particularly to a display method capable of reducing edge ripple.
在製造顯示面板的過程中，積體電路與基板的接合係利用高溫貼合(bonding)，由於積體電路熱漲冷縮的程度比基板嚴重，導致上下基板的間距發生變化，造成基板內液晶分子受到擠壓使得排列密度不一致，因使顯示裝置顯示時顯示面板與積體電路貼合區域周遭在顯示黑畫面時會產生類似弧形的亮點波紋(COG,chip on glass,mura)。In the process of manufacturing the display panel, the bonding between the integrated circuit and the substrate is performed by high-temperature bonding. Since the degree of thermal expansion and contraction of the integrated circuit is more serious than that of the substrate, the pitch of the upper and lower substrates changes, resulting in liquid crystal in the substrate. The molecules are squeezed so that the arrangement density is inconsistent, because the display panel and the integrated circuit bonding area display a black-like image (COG, chip on glass, mura) when the display device is displayed.
特別是當多個積體電路與基板高溫貼合(bonding)，導致多個弧形的亮點波紋的產生，在顯示全黑畫面時，使用者的感受特別明顯。In particular, when a plurality of integrated circuits are bonded to the substrate at a high temperature, resulting in generation of a plurality of curved bright spot ripples, the user's feeling is particularly noticeable when displaying a full black screen.

FIG. 1 is a schematic diagram of a display panel 100 applied to an embodiment of the present invention. The display panel 100 includes a pixel matrix 120 of M pixel columns, a data driving unit 130 , and a gray scale adjusting unit. 140. Each pixel column has a plurality of pixel units 125 disposed along the first direction X, and the M pixel columns are adjacently disposed in parallel along a second direction Y substantially perpendicular to the first direction X, wherein the first direction X may be the column direction and the second direction Y may be the row direction. Each pixel array is electrically connected to the data driving unit 130 for receiving the data signal. And the M pixel columns can be divided into a group of first pixel columns 121 and N groups of second pixel columns 122, wherein a group of first pixel columns 121 can comprise a plurality of pixel columns, and each group of second The pixel columns 122 may respectively contain at least one pixel column, where N is a positive integer greater than or equal to 1 and M is a positive integer greater than N, in other words, the number of columns of the first pixel column and the second group of N groups The total number of columns in the prime column is equal to M. The display panel 100 further includes a substrate 110, and the data driving unit 130 may include at least one integrated circuit 132 and is disposed on the substrate 110 by using a high-temperature chip on glass (COG), and the pixels of the M pixels are arranged. The matrix 120 is also disposed on the substrate 110, wherein the N sets of second pixel columns 122 are disposed between the data driving unit 130 and the set of first pixel columns 121.
請參考第2圖，第2圖係為應用於本發明之一實施例之顯示方法200流程圖，如第2圖所示之方法200包括下列步驟，但不限於 以下次序，舉例來說，步驟S210可在步驟S220之前或之後執行，步驟S230亦可在步驟S240之前或之後執行：S210：於第T幀接收第一畫素列之第一組資料訊號，其中T係為一正整數；S220：於第T幀接收N組第二畫素列之第二組資料訊號，其中第二組資料訊號包含實質上相同之暗態灰階訊號；S230：第一畫素列於第T幀顯示第一組資料訊號；S240：N組第二畫素列於第T幀顯示灰階大於第二組資料訊號之第三組資料訊號。Please refer to FIG. 2, which is a flowchart of a display method 200 applied to an embodiment of the present invention. The method 200 shown in FIG. 2 includes the following steps, but is not limited thereto. In the following order, for example, step S210 may be performed before or after step S220, and step S230 may also be performed before or after step S240: S210: receiving the first group of data signals of the first pixel column in the Tth frame, wherein The T system is a positive integer; S220: receiving the second group of data signals of the N sets of the second pixel columns in the Tth frame, wherein the second group of data signals includes substantially the same dark state gray level signal; S230: the first picture The prime column displays the first group of data signals in the T frame; and the second group of the N pixels in the Nth frame displays the third group of data signals whose grayscale is greater than the second group of data signals.
請再次參考第2圖並搭配第3圖，顯示面板100包含至少一驅動單元、第一畫素列121、及設置於至少一驅動單元與第一畫素列121之間的N組第二畫素列122，且顯示面板100於每一幀(frame)更新一次顯示畫面，其中驅動單元可為第1圖之資料驅動單元130；於步驟S210第T幀接收到第一畫素列121的第一組資料訊號D1，於步驟S220接收到N組第二畫素列122的第二組資料訊號D2；當N等於1時，換言之，只有一組第二畫素列122，若第二組資料訊號D2的灰階實質上全為相同的暗態灰階訊號，可例如是黑畫面L0時，於步驟S230第一畫素列121於第T幀顯示第一組資料訊號D1；於步驟S240第二畫素列122顯示灰階大於第二組資料訊號D2的灰階的第三組資料訊號D3。本實施例較佳的第三組資料訊號D3灰階可實質上為比第二組資料訊號D2的灰階亮度高一階的L1。如此一來，靠近資料驅動單元130的第二畫素列122容易產生的弧形亮點波紋(COG mura)能夠經由灰階調整單元140將第二組資料訊號D2校正為大於黑畫面L0的第三組資料訊號D3，則能夠降低甚至抑制人眼對於弧形亮點波紋的感受。其中資料訊號的灰階(grey level scale)表示畫素可顯示不同程度的灰色，例如是由8個位元組成的L0~L255；L0表示 暗態的最黑灰階，一般可稱作黑畫面L0；而L255表示亮態的最高灰階，一般可稱為白畫面L255。Referring to FIG. 2 again, in conjunction with FIG. 3 , the display panel 100 includes at least one driving unit, a first pixel column 121 , and N sets of second paintings disposed between the at least one driving unit and the first pixel column 121 . The display panel 100 updates the display screen once every frame, wherein the driving unit can be the data driving unit 130 of FIG. 1; the first pixel column 121 is received at the Tth frame in step S210. A set of data signals D1 receives the second set of data signals D2 of the N sets of second pixel columns 122 in step S220; when N is equal to 1, in other words, there is only one set of second pixel columns 122, if the second set of data The gray level of the signal D2 is substantially the same dark state gray signal. For example, when the black screen L0 is displayed, the first pixel column 121 displays the first group of data signals D1 in the T frame in step S230; The two-pictured column 122 displays a third set of data signals D3 having a gray level greater than the gray level of the second set of data signals D2. The preferred third set of data signal D3 gray scales in this embodiment may be substantially L1 one step higher than the gray scale brightness of the second set of data signals D2. In this way, the curved bright spot ripple (COG mura) which is easy to generate near the second pixel column 122 of the data driving unit 130 can correct the second group of data signals D2 to be greater than the third of the black frame L0 via the grayscale adjusting unit 140. The group data signal D3 can reduce or even suppress the human eye's perception of curved bright spots. The gray level scale of the data signal indicates that the pixels can display different degrees of gray, for example, L0~L255 consisting of 8 bits; L0 means The darkest gray level of the dark state is generally called black picture L0; and L255 is the highest gray level of the bright state, which is generally called white picture L255.
第3圖係為本發明之一實施例之資料訊號顯示灰階示意圖。請合併參考第1-3圖，首先提供具有資料驅動單元130、第一畫素列121、及設置於資料驅動單元130與第一畫素列121之間的N組第二畫素列122的顯示面板120，其中N係為正整數；於第T幀時，接收第一畫素列121之第一組資料訊號D1，其中第一組資料訊號D1可為全黑畫面或者是非全為全黑畫面之影像；於第T幀時接收N組第二畫素列122之第二組資料訊號D2，若第二組資料訊號D2為實質上相同之暗態灰階訊號，所述之暗態灰階可例如是灰階近趨於全黑之影像，則N組第二畫素列122於第T幀顯示灰階大於第二組資料訊號D2之第三組資料訊號D3。如第3圖所示，因此邊緣弧形波紋效應對於人眼的影響可相對的減少許多，提升畫面品質。Figure 3 is a schematic diagram showing the gray scale of the data signal display according to an embodiment of the present invention. Referring to FIG. 1-3, a data driving unit 130, a first pixel column 121, and N sets of second pixel columns 122 disposed between the data driving unit 130 and the first pixel column 121 are first provided. The display panel 120, wherein N is a positive integer; in the Tth frame, receiving the first group of data signals D1 of the first pixel column 121, wherein the first group of data signals D1 may be all black pictures or not all black The image of the picture; receiving the second group of data signals D2 of the N sets of the second pixel columns 122 at the Tth frame, and if the second group of data signals D2 are substantially the same dark state gray level signals, the dark state gray The order may be, for example, an image in which the gray scale is nearly black, and the N sets of the second pixel array 122 display the third group of data signals D3 whose gray scale is greater than the second set of data signals D2 in the Tth frame. As shown in Fig. 3, the effect of the edge arc ripple effect on the human eye can be relatively reduced, and the picture quality is improved.
於本發明之一實施例中，第一組資料訊號D1及第二組資料訊號D2可分別於一幀同時施加黑畫面L0的影像資料至顯示面板100，例如是發生於顯示面板100於待機狀態、休眠模式等，當靠近積體電路132附近之N組第二畫素列122的第二組資料訊號D2大體上全為暗態灰階訊號時，有可能造成弧形波紋的產生，因此將第二畫素列122調整顯示灰階大於第二組資料訊號D2的灰階的第三組資料訊號D3能夠避免弧形波紋的產生，提升影像畫面品質。In an embodiment of the present invention, the first group of data signals D1 and the second group of data signals D2 can simultaneously apply the image data of the black screen L0 to the display panel 100 in one frame, for example, when the display panel 100 is in the standby state. In the sleep mode, etc., when the second group of data signals D2 of the N sets of the second pixel columns 122 near the integrated circuit 132 are substantially all dark gray-scale signals, the arcuate ripple may be generated, so The second pixel array 122 adjusts the third group of data signals D3 that display gray scales larger than the gray level of the second group of data signals D2 to avoid the generation of curved ripples and improve the image quality.
於本發明之另一實施例中，於一幀接收到第一畫素列121的第一組資料訊號D1的灰階可以為非全為L0，接收到N組第二畫素列122的第二組資料訊號D2係全為L0。如第3圖所示，即使畫素矩陣120內 的顯示區域中並未全部顯示暗態灰階訊號，然而當靠近積體電路132附近之N組第二畫素列122的第二組資料訊號D2大體上全為暗態灰階訊號時，亦可能造成弧形波紋的產生，因此將第二畫素列122調整顯示灰階大於第二組資料訊號D2的灰階的第三組資料訊號D3也能夠避免弧形波紋的產生，提升影像畫面品質。In another embodiment of the present invention, the gray level of the first group of data signals D1 received in the first pixel column 121 in one frame may be not all L0, and the Nth group of the second pixel columns 122 are received. The two sets of data signals D2 are all L0. As shown in Figure 3, even within the pixel matrix 120 The dark grayscale signals are not all displayed in the display area, but when the second set of data signals D2 of the N sets of the second pixel columns 122 near the integrated circuit 132 are substantially all dark gray signals, The arcuate corrugation may be generated. Therefore, adjusting the second pixel sequence 122 to display the third group of data signals D3 whose gray scale is greater than the gray level of the second group of data signals D2 can also avoid the generation of curved corrugations and improve the image quality. .
請參考第4圖，第4圖係為本發明之另一實施例之資料訊號顯示灰階示意圖。於本發明之另一實施例中，當N大於等於2時，換言之，包含有兩組以上的第二畫素列122時。第一組第二畫素列122平行於最靠近之第一畫素列121相鄰設置，其餘之第二畫素列122對應第一畫素列121由近至遠依序平行設置於第一畫素列121與積體電路132之間。其中，每一組第二畫素列122的列數目實質上可為相同或者不相同，可依照使用者需求自行規劃設計，第三組資料訊號D3可依照N組第二畫素列122相對第一畫素列121的距離遠近，由鄰近至遠離依序逐漸緩緩增加灰階亮度，例如最靠近第一畫素列121之第一組第二畫素列122顯示之第三組資料訊號為D31，相鄰第一組第二畫素列122之第二組第二畫素列122顯示之第三組資料訊號為D32，最遠離第一畫素列121但最靠近積體電路132之第N組第二畫素列122顯示之第三組資料訊號為D3N，其中灰階亮度D3N>D32>D31>D2，以此類推，利用漸層的方式使得位於畫素矩陣120邊緣且靠近積體電路132之N組第二畫素列122分別各自顯示相較於全黑畫面，灰階稍微亮一些的資料訊號，對於使用者來說，如此一來，人眼就不會感受到N組第二畫素列122與第一畫素列121有明顯的灰階差異，其餘方法皆與所述之方法相似，不另贅述。Please refer to FIG. 4, which is a schematic diagram showing the gray scale of the data signal display according to another embodiment of the present invention. In another embodiment of the present invention, when N is greater than or equal to 2, in other words, when two or more second pixel columns 122 are included. The first group of second pixel columns 122 are arranged adjacent to the first pixel column 121 adjacent to the first pixel column 122, and the remaining second pixel columns 122 are arranged in parallel with the first pixel column 121 from the near to the farthest. The pixel array 121 is connected to the integrated circuit 132. The number of columns of each group of the second pixel columns 122 may be substantially the same or different, and may be planned and designed according to user requirements. The third group of data signals D3 may be in accordance with the N group of second pixels 122. The distance between the pixels 121 is far and near, and the gray level brightness is gradually increased from adjacent to far away. For example, the third group of data signals displayed by the first group of second pixels 122 closest to the first pixel column 121 is D31, the third group of second pixel columns 122 adjacent to the first group of second pixel columns 122 display the third group of data signals D32, the farthest from the first pixel column 121 but closest to the integrated circuit 132. The third set of data signals displayed by the second set of pixels 122 of the N group is D3N, wherein the gray scale brightness D3N>D32>D31>D2, and so on, is located on the edge of the pixel matrix 120 and close to the integrated body by using a gradation method. The N sets of second pixel columns 122 of the circuit 132 respectively display data signals whose gray scale is slightly brighter than the all black screen.
