The (4) data control method is to first receive the first display line data including the first pixel data displayed on the first pixel, and then determine the second according to the relationship between the first pixel data and the preset range. The second halogen data displayed on the second element in the line data is outputted by the polarity of the same as the first-halogen data. When it is determined that the polarity of the first pixel data is the same as the polarity of the second data = the data is output, a specific one of each subsequent line of the display data received by the fixed time within a predetermined time is output. The polarity and the polarity of the first-halogen data are output. Wherein, the subsequent pixels for displaying the subsequent halogen data, the second pixel and the first pixel receive the halogen data from the same path. In an embodiment of the present invention, the display data control method - when the two pixels of the data are output with the same polarity, the length of the preview time is fixed, and each of the subsequent displays is successively received. - The polarity of the subsequent morphemic data is the same as that of the ninth symmetry; and when the first morpheme data is determined to be different from the second ===, the subsequent display line data is received (4) *', '代代In the case of the 画 资料 资料 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 Deciding to make the second pixel data be judged by the output of the m-pixel data when the output is broken; in contrast, if the grayscale value of the pen-*昼素 data is determined to fall outside the aforementioned preset range , the polarity of the time is the same Ο "" ^ 〇 ~ another - in the embodiment, when the grayscale value of the data is falling, the preset range just described is set between 4 and 59. The output of the fresh surface (4) is applied to determine the polarity when the displayed data is output.

In addition 'control After receiving the first display line data, the unit then receives the second display material, and then receives other subsequent display data, wherein the first display data has - the first pixel data. The line data has a second pixel data, and each subsequent display line 2 has a subsequent pixel data and the first element data, the second element '_, the bead material and the subsequent pixel data are Provided to the same data supply line. Control sheet 70 is based on the relationship between the first pixel data and a certain preset range. No. 201205538 - When the pixel data is read at the time of reading, if the polarity of the control element is the same as that of the second pixel data, then each of the strips is fixed within a predetermined time. The rear axle shows (4) that the polarity of the subsequent sputum material is output the same as the polarity when the first-pixel data is outputted. / In the embodiment of the invention, the control unit has a register. And the control unit determines how to set the register according to the first-picture (4) grayscale value and the preset. Or, in one embodiment, if the grayscale value of the j-th material falls within the foregoing preset range Then, the control unit sets the temporary IJ to be the _preset value; conversely, if the gray level of the first quaternary (four) falls outside the preset range, the control unit sets the temporary register to the second preset value. In addition, in an embodiment of the present invention, when the temporary storage device is the second preset value, the control unit stops the relationship between the grayscale value of the first-dimensional data and the preset range, and After the device is set to a predetermined length of time starting from the second preset value, the control early element resets the register to the aforementioned first preset value. Since the invention can control the manner in which the data is provided, the polarity of the data supply can be adjusted under the condition that the data can be displayed in the month b, and the image instability caused by the variation of the data polarity can be reduced. The above and other objects, features, and advantages of the present invention will become more apparent and understood by the appended claims appended claims [Embodiment] In order to solve the higher color resolution when the Adaptive Column Inversion technology (Frame Rate Control ' FRC) technology is used, the flat display will have vertical stripes on the surface. The technician performed experiments and analysis on the problem of rolling the horizontal lines and the like to break the uniformity of the overall picture. According to the results of the experiment, it was found that these lines were caused by the irregular interlacing of bright and dark lines. However, the irregular interlacing of these bright and dark lines does not appear in 201205538 on all image data, but only on the grayscale image (4). With 256 grayscale image data and 2-bit frame number control technology, when the image data between grayscale values of 16 to 18 or grayscale values of 241 to 243 appears, the image of the image is displayed. The above-mentioned road test will be produced; in contrast, other gray-scale image data will not be produced in Xianke. Therefore, it can be inferred that if the image of the P (4) image is in the gradual scale, then a stable image display quality should be obtained. heart

In order to achieve this;; the accumulated brightness becomes the actual brightness of the wire, the control method of the prior art is shown in Figure 1. Please refer to FIG. 1 , which is a flow chart of the implementation steps of the current data polarity control method. In Figure 1 + 'money receives a display line data in step S1 (8), and judges the gray scale value of each pixel data in the line data to confirm the pixel Whether the grayscale value of the data falls within a certain range (step sl1). If the grayscale value of the secondary material falls within the specific range, the polarity of the halogen data supplied to the supply line of the second material is set to be the same as the polarity of the current pixel material (step S106); In contrast, if the grayscale value of the pixel data does not fall within this specific range, then the polarity of the pixel supplied to the same-data supply line is different from the polarity of the current data. Sl〇4). After judging the 'one pixel data, it is necessary to confirm whether the entire display line has been judged (step S108); if all the judgments have been completed, the next display is received (return to step S100), otherwise it is returned. Step S102 is to determine the relationship between the next search and the specific range. However, in this method, when the polarity is constantly changing, the flat display will produce the 201205538 bright and dark line display result, and thus the vertical grain and the rolling transverse twill will appear on the display screen to break the uniformity of the overall kneading surface. Make the display quality worse. Therefore, the present invention proposes the following techniques to be improved. Referring to Figure 2, there is shown a circuit block diagram of a flat panel display in accordance with an embodiment of the present invention. In the present embodiment, the flat panel display 2 has a display area 200, a control unit 21A, a plurality of elementary control lines 22A to 226, and a plurality of data supply lines 230 to 238. The display area 200 has a plurality of halogens 240 to 278. The pixels 240 to 278 receive the halogen data from one of the data supply lines 230 to 238 by the control of the pixel control lines 220 to 226, respectively. This shows the corresponding image. Each of the pixel control lines 220 to 226 is electrically coupled to one of the pixels to control whether the partially coupled pixels are received or not; similarly, each of the data supply lines 23〇 238 is also electrically coupled to one of the components of the halogen to provide the halogen data to the electrically coupled partial elements. As shown, the pixel control line 220 is electrically coupled to the pixels 240, 242, 244, 246, and 248' pixel control lines 222 electrically coupled to the cells 25, 252, 254, 256, and 258'. The pixel control line 226 is electrically coupled to the pixels 27〇, 272, 274, 276, and 278; the data supply line 230 is electrically coupled to the pixels 24〇, 25〇# and 270' data supply lines 232. The data supply line 234 is electrically coupled to the pixels 244, 254, and 274, and the data supply 236 is electrically coupled to the pixels 246, 256, and 276, and the data supply line 238 is electrically connected. Sexually coupled to halogens 248, 258 and 278. In the present embodiment, "all display line data" is first transmitted to the control unit 210. After receiving the display line data, the control unit 210 sequentially supplies the display line data to the data supply lines 230-238, and electrically receives the pixels of the same pixel control lines 220-226. Go to the same display line data contains the data. If the display line data is named [S] 8 201205538 in the order received by the control unit 21〇, the control unit 210 will sequentially receive the display line data of the first display line data, the second display line data, the third display line data, and the like. . The first display line data is provided on the data supply lines 230 to 238, so that the pixels 240 to 248 electrically coupled to the control unit 220 can respectively receive one of the first display lines. The pixel data; next, the second display line data is also provided to the data supply lines 230 to 238, but at this time, the different pixel control lines (for example, the pixel control line 222 or 226) are different. The morpheme (relatively like pixels 250 to 258 or 270 to 278) can receive one of the gold data in the second display line data. ^ • Since the phenomenon of bright and dark lines is the result of the constant conversion of the polarity of the pixel data provided by the same data supply line, the following will be discussed for a specific data supply line. Those skilled in the art are aware that such discussions can also be applied to pixels that are electrically coupled to other data supply lines. ~ Assume that the aforementioned first display line data contains a pixel data (hereinafter referred to as a first pixel data) displayed on the pixel 242' and the aforementioned second display line data contains one for displaying on the pixel 252. The upper pixel data (hereinafter referred to as the second picture material)' then the control unit 210 determines the polarity of the second pixel data to be output according to the relationship between the first pixel data and a certain range. And if the control unit 210 determines that the polarity of the first pixel data and the second pixel data are the same, the control unit 21 固定 fixes each subsequent display line data that is successively received for a predetermined length of time (for example, In the foregoing third display line data, the subsequent pixel data displayed on the subsequent pixels (for example, the halogen 272) electrically coupled to the same data supply line 232 is outputted with the first halogen data. Have the same polarity.

As shown in Figs. 2 and 3, the control unit 21 first receives the first display line data (step S300), and then determines the polarity for each element. First, the control unit 210 first determines whether the current data to be processed has been set to be the same polarity as a certain pixel data (step S3i). If there is no such setting result before, the control unit 21 determines whether the grayscale value of the pixel data falls within a certain range for the currently processed pixel data (step S3〇2). According to the above example, if the image data of 256 gray scales is simulated by the 2-bit frame number control technology, the range of the image data of each frame will be 0 to 63, and the specific range here is It is between 4 and 59 ^. In other words, in the present embodiment, the control unit 210 determines whether the gray scale value of the current halogen data falls between 4 and 59, and determines the polarity of the output of the other pixels according to the result of the judgment & If it is determined in step S302 that the pixel data does not fall between 4 and ^, the control unit 210 sets the next pixel data and the current pixel data supplied to the same data supply line as Different polarity (step S304). For example, if it is judged that the gray scale value of the aforementioned first-halogen data is G~3 or 60~63 (not falling between 4 and 59), then the control unit 2Κ will provide the next one. The polarity of the second pixel data to the data supply line 232 is set to be different from the polarity of the first pixel data. Or, the same ... Once it is judged that the gray scale value of the aforementioned second pixel data is G~3 or 6()~63, then the control early TC210 will provide the next one to the data supply line 232 (that is, The output polarity of the material supplied to the data supply line 'the third display line data is set to be different from the output polarity of the second picture. · Conversely, if it is determined in step S302 that this one is early π· 210 years old - A picture material provided to the same-item data supply line 201205538 The material and the target pixel data are set to the same polarity (step S306). For example, after the judgment, the gray of the first-pixel data is found. The control unit 21 of the order value of 4 to 59> will set the next one that is supplied to the data supply line to be the same as the one of the first material. The gray level value of the second pixel data is between two, then the control unit 210 provides the next pixel data to the data supply line 232 (that is, the third display line data is provided to the data supply line 232). The pixel's output polarity is set to Two outputs of the same polarity. Magic angle was butoxy inch
在經過步驟S304或S306的設定之後，控制單元21〇 判斷是否已經觸完目前準備（或正在)輸出賴示線資料中 的所有畫素資料(步驟S3G8)。假若還沒判斷完所有的畫 料，那麼流程將回到步驟S31〇並開始對下一個畫素資二進 判斷與相對應的設定；相對的’如果這—條顯示線資料中的圭 素資料都已經被判斷並設定完畢，則控制單元21〇將接收下二 條顯示線資料(步驟S300)並進行需要的判斷。應注意的是，在 本實施例中雖然是在所有晝素資料都判斷完畢之後才接收下 一條顯示線資料，但實際上判斷與設定的操作可以與下一條顯 示線資料的接收操作同時進行，或者甚至可以先開始接收下一 條顯示線資料之後再進行目前這一條顯示線資料的判斷與相 對應的設定。 ' 回到步驟S310’假若先前在步驟幻1〇中發現這個晝素資 料被設定為與先前的某一個晝素資料相同極性，那麼控=單元 210會進一步判斷從這一次固定相同極性開始到目前為止的= 間區間是否已經超過預定的時間長度(步驟S312)。假如已經超 過預定的時間長度，那麼控制單元210就會重新啟動針對目前 201205538 畫素資料的灰階值與預設範圍之間的判斷(步驟S3〇2);相反 的，假如還在預定的時間長度之内，那麼控制單元210就會直 接將下一個提供到同一條資料供應線上的晝素資料的輸出極 性没疋為與目前的晝素資料的輸出極性相同。报明顯的，如果 此次的固定相同極性是從第一晝素資料開始的話，那麼此處所 設定的輸出極性也會跟第一晝素資料的輸出極性相同。After the setting of step S304 or S306, the control unit 21 determines whether or not all of the pixel data currently being prepared (or in the process of outputting) of the line material has been touched (step S3G8). If all the materials have not been judged yet, the process will return to step S31 and start to judge the next picture and the corresponding settings; the opposite 'if this line' displays the information in the line data. After having been judged and set, the control unit 21 will receive the next two pieces of display line data (step S300) and make the necessary judgment. It should be noted that in the embodiment, although the next display line data is received after all the meteor data is judged, the actual judgment and the set operation may be performed simultaneously with the receiving operation of the next display line data. Or you can even start receiving the next display line data before making the judgment and corresponding setting of the current display line data. 'Returning to step S310', if it is found in the step phantom that the morpheme data is set to be the same polarity as the previous morphological data, then the control unit 210 will further judge from the time when the same polarity is fixed to the present Whether or not the interval between them has exceeded a predetermined length of time (step S312). If the predetermined length of time has elapsed, the control unit 210 restarts the judgment between the grayscale value and the preset range for the current 201205538 pixel data (step S3〇2); conversely, if it is still at the predetermined time Within the length, the control unit 210 directly outputs the output polarity of the next pixel data supplied to the same data supply line to be the same as the output polarity of the current halogen data. It is obvious that if the fixed polarity of this time is from the first element data, then the output polarity set here will be the same as the output polarity of the first element data.
應注意的是，此處所謂的預定的時間長度可以有很多種計 篁類型。舉例I說’可以把-個固定的時間長度直接做為預定 的時間長度，或者可以把接收並設定固定數量(如三條)的顯示 線資料的時間做為預定的時間長度，又或者也可以把顯示固定 數里（如二條)的顯示線資料的時間做為預定的時間長度。 根據上述步驟，一旦有一個晝素資料(例如第二晝素資料) 的輸出極性被設定為與另一個畫素資料(例如第一 ^素資料) 的輸出極性相同，那麼後續在預定的時間長度之崎處理的被 提，到同-條資料供應線上的晝素:#料的輸出極性也就會被 設定成跟第-晝素資料的輸出極性相同；或者，從另—個角产 來說，後續在狀的時間長度之内所處理的被提供到同一條J 料供應線上的畫素資料會維持與第—晝素資料有相同的輸出 絲Μ。 、再者’除了以軟體方式來控制畫素極性是否轉變之外，此 可以利用硬體的方絲控制畫素極性轉變與否。如圖2坪 工二=單元210中進一步包含了-個暫存器212，這一個f 子斋 i 4可以被設^成兩個不同的值。當控制單元21〇在 =tS3〇4的設定時，暫存器212會被設定為第一種數值 H第Γ預没值）；相對的’當控制單元210在進行步驟_ β又疋，’暫存器212會被設^為第二種數值(後稱第二預設 !2 201205538 值）。 必須注意的是，由於本發明 應線230〜238上的兩個書供至同—個資料供 此暫存it犯較佳地應姉轉換與㈣設定，因 應線上的像素資料的極_換二特定資料供 f :以:报多位元’而每一位元則對b應到二:資:二: 線，且以數值0與i代表不同的極 =貝科供應 ZTtM7t ^It should be noted that the so-called predetermined length of time here can be of many types. Example I says that 'a fixed length of time can be directly used as a predetermined length of time, or the time for receiving and setting a fixed number (such as three) of display line data can be made as a predetermined length of time, or it can be The time for displaying the display line data in a fixed number (such as two) is set as the predetermined length of time. According to the above steps, once the output polarity of one of the pixel data (for example, the second pixel data) is set to be the same as the output polarity of the other pixel data (for example, the first element data), then the subsequent length of time is predetermined. The razor of the Kawasaki processing, to the data of the same - the data supply line: the output polarity of the material is also set to be the same as the output polarity of the first-formal data; or, from another angle The pixel data that is processed to the same J material supply line processed within the length of time will maintain the same output as the first-order data. In addition to the software to control whether the pixel polarity is changed, this can use the hardware square wire to control the polarity change of the pixel. As shown in Fig. 2, the unit 2 = unit 210 further includes a register 212, which can be set to two different values. When the control unit 21 is at the setting of =tS3〇4, the register 212 is set to the first value H and the second value is not); the opposite 'when the control unit 210 is performing the step _β, ', ' The register 212 will be set to the second value (hereinafter referred to as the second preset! 2 201205538 value). It must be noted that, since the two books on the line 230 to 238 of the present invention are supplied to the same data for the temporary storage, it is better to convert and (4) the setting, and the pixel data on the line is changed to the second.

For example, 'control unit ^〇: when the gray level value falls within the preset range, the temporary preset value is set to 'the gray level of the first-order data is set to the preset memory 11212. Two preset values. When the register 2= is the second preset value, the control unit 21〇 stops determining the relationship between the grayscale value of the corresponding pixel and the preset range, and is set from the register 212. The value of the register 212 is not changed within a predetermined length of time after the start of the first pre-value is not until the predetermined time length is exceeded, and the register 212 is reset to the first preset value or other non-second preset value. The value is such that the control unit 210 starts the related determination and setting operation again.
