[0015] ❹ [0016] [0017] 099127822 得液晶顯示裝置存在燃燒風險較高之不安全因素。 進一步深層次分析雜訊之來源，我們發現：落入人耳聽 覺範圍之雜訊（聽得見之雜訊）主要是在液晶顯示裝置在 顯示某些特定畫面時產生的，而當液晶顯示裝置顯示非 特定晝面時，雜訊非常小，且通常不易被發覺。舉例來 說，液晶顯示裝置之矩陣排列之畫素中，如果出現連續 複數行畫素顯示白畫面，且與上述晝素相鄰之連續複數 行畫素顯示黑晝面之情況時，就會產生較大之聽得見之 雜訊。 通過分析發現，液晶顯示裝置顯示此類型之特定畫面時 ，其中黑畫面進行極性切換時，由於同一資料線上之電 壓之變化較大，使得印刷電路板上之陶瓷電容之充放電 電流瞬間變化較大，進而陶瓷電容之電介質在電場方向 膨脹，在垂直於該電場方向之平面上收縮，從而引起印 刷電路板之膨脹和收縮，產生振動與雜訊。由此，根據 上述分析結果，本發明提供以下具體實施方式來改善聽 ' ' ' 2 得見之雜訊。 請參閱圖1，其本發明液晶顯示裝置第一實施方式之等效 電路示意圖。該液晶顯示裝置100包括一時序控制電路 110、一資料驅動電路140、一掃描驅動電路150及一液 晶顯示面板160。該時序控制電路110包括一資料分析模 組120及一時序控制模組130。

099127822 A liquid crystal display device has an unsafe factor of high combustion risk. Further deep analysis of the source of noise, we found that: the noise (audible noise) falling into the human ear hearing range is mainly generated when the liquid crystal display device displays certain specific images, and when the liquid crystal display device When displaying non-specific faces, the noise is very small and often not easily noticeable. For example, in a pixel of a matrix arrangement of a liquid crystal display device, if a continuous plurality of pixels are displayed to display a white screen, and a continuous plurality of pixels adjacent to the above-mentioned pixels display a black surface, a generation occurs. Larger audible noise. Through analysis, it is found that when the liquid crystal display device displays a specific picture of this type, when the polarity of the black picture is switched, the charge and discharge current of the ceramic capacitor on the printed circuit board changes instantaneously due to the large change of the voltage on the same data line. Then, the dielectric of the ceramic capacitor expands in the direction of the electric field and shrinks in a plane perpendicular to the direction of the electric field, thereby causing expansion and contraction of the printed circuit board, generating vibration and noise.

[0024] [0024] [0024] 099127822 Further, when the plurality of pixels 165 of the liquid crystal display panel 160 display a frame of image, if the gray level of a pixel 165 is lower than a first predetermined gray level, Then define the pixel 16 5 to display a black picture. For example, for an image of 2 5 6 gray scales, the first predetermined gray scale may be 32 gray scales, and preferably, the first predetermined gray scale may also be 16 gray scales. In contrast, if a pixel 165 displays a gray level higher than a second predetermined gray level, the pixel 165 is defined to display a white picture. For example, for an image of 256 gray scales, the second predetermined gray scale may be 200 gray scales, and preferably, the second predetermined gray scale may also be 224 gray scales. Of course, the values of the first and second predetermined gray levels can also be set according to actual needs. Further, when the multi-pixel 165 of the liquid crystal display panel 1 & amp displays an image, if a pixel of a row of pixels 165 includes more than 70% of the pixels to display a black image, then the definition of the pixel 165 displays black 昼The face, that is, the line of pixels 165 belongs to the pixel line displaying the black picture. In contrast, if a line of pixels 165 includes more than 70% of the pixels 165 to display a white picture, then the line of pixels is defined to display a white picture, that is, the line pixels 1 and 5 belong to the prime line of the white picture. Of course, the above percentage can also be changed according to actual needs. For example, in other modified embodiments, a pixel 165 including more than 9% of the pixels in the line 165 can be defined to display a black picture (or a white picture). 165 is defined as a pixel line that displays a black screen (or a white screen). Specifically, when the data analysis module 120 analyzes one frame of image data, when n frames of pixels 165 are consecutively displayed in one frame of image data, when m pixels 165 are continuously displayed, the black image is displayed. Where ng4,n>mg2,m and η are all natural numbers, the data analysis module 12〇 outputs a first polarity inverse form number Α0101 page 12/total 40 pages '9202048872-0 201209793 turn control signal to the data driver Circuit 140. The data driving circuit 140 processes the data signal according to the first polarity inversion control signal to generate a complex gray scale voltage and supplies the voltage to the liquid crystal display panel 160, so that the plurality of pixels 165 of the liquid crystal display panel 160 display the frame image. In the case of the image, in all of the m rows of pixels 165 which are displayed continuously and which display a black picture, all the pixels 165 in the same column have the same polarity (that is, the polarity does not change). [0025] Further, in an embodiment, when the data analysis module 120 analyzes one frame of image data, the data is continuously displayed only when the image data of one frame is continuously displayed. When the m-line pixel 165 displays a black screen and the other nm-line pixels 165 display a white screen, the data analysis module 120 outputs the first polarity inversion control signal. For example, when n=6, m=3 in the frame image data, that is, 3 rows (m rows) including continuous display, the pixel 165 displays a black screen, and the other 3 rows (nm rows) of pixels 165 are displayed. When the white screen is displayed, the data analysis module 120 outputs the first polarity inversion control signal. In a modified embodiment, when the data analysis module 120 analyzes one frame of image data, only the n pixels of the continuous display of one frame of image data are continuously displayed. The line pixel 165 displays a black picture, and the pixels 165 of at least two consecutive rows of the other nm line pixels 165 display a white picture, and the data analysis module 120 outputs the first polarity inversion control signal. For example, when n = 6, m = 3 in the frame image data, that is, 3 lines (m lines) of pixels 165 including continuous display display black pictures, and two lines of other 3 lines (nm lines) When the continuously displayed pixel 165 displays a white screen, the data analysis module 120 outputs the first polarity inversion control signal. [0027] More specifically, the data driving circuit 140 controls the polarity inversion mode of one frame according to the first polarity inversion 099127822 form number A0101 page 13 / total 40 page 0992048872-0 201209793 control signal. In an embodiment, when the plurality of pixels 165 of the liquid crystal display panel 160 are displayed, the polarities of all the pixels 165 in the same column are the same. Specifically, the data driving circuit 140 is configured according to the first The polarity inversion control signal can control the plurality of pixels 165 of the liquid crystal display panel 160 to display the frame image in a column inversion or frame inversion manner. Among them, column inversion includes single column inversion and double column inversion. Referring to FIG. 2, single column inversion, double column inversion and frame inversion are respectively shown in (1), (2) and (3) of FIG. 2 . . [0028] Further, when the data analysis module 120 analyzes one frame of image data, when one frame of image data does not meet the above-mentioned “continuous display of the η row element 165, the m rows of pixels are continuously displayed. 165 shows a black screen, wherein in the case of η 2 4 , n > m22 ′′, the data analysis module 120 can output a second polarity inversion control signal to the data driving circuit 140. The data driving circuit 140 processes the data signal according to the second polarity inversion control signal to generate a complex gray scale voltage and supplies the voltage to the liquid crystal display panel 160, so that the plurality of pixels 165 of the liquid crystal display panel 160 are inverted. The drive mode displays the frame image. Please refer to FIG. 3, which is a schematic diagram of several common inversion driving modes. The common inversion driving method may be dot inversion, one line plus two line inversion, single line inversion or double line inversion, wherein dot inversion, one line plus two line inversion, single line inversion and double line inversion respectively (1), (2), (3), and (4) of Fig. 3 are shown. Please refer to FIG. 4, which is a schematic diagram of a first embodiment of the data analysis module 120. The data analysis module 120 includes a register 121, a determination circuit 123 and a polarity inversion control circuit 125. The register 121 is configured to sequentially receive and temporarily store an external circuit (such as a low-voltage differential signal connector) to provide image data of each frame of 099127822 Form No. A0101 Page 14/Total 40 Page 0992048872-0 201209793' The circuit 123 is configured to read image data of each frame stored in the temporary storage unit 121, analyze the image data of each frame, and control the output of the polarity inversion control circuit 125 according to the analysis result.

The random number generator 122 sequentially generates a complex array random number and provides the complex array random number to the data control circuit 124. Each group of random numbers includes k addressable addresses, and the k addressable addresses are respectively corresponding to k値 pixel data in a row of pixels 165. The data control circuit 124 reads k pieces of pixel data in a row of pixels from one frame image data of the register 121 according to the k address addresses and analyzes the k pixel data. If at least 70% of the pixel data of the k-pixels belongs to the black-screen data, then the pixel 165 belongs to the pixel line displaying the black image. The data control circuit 124 further analyzes the k pixel data according to the above analysis, and counts the black picture pixel row and the total pixel number, and when there is the above n 4, n > m22, the data control The circuit 124 controls the polarity inversion control circuit 125 to output the first polarity inversion control signal; otherwise, the data control circuit 124 controls the polarity inversion control circuit 125 to output the second polarity inversion control signal. The value of 'k can be set according to actual needs. For example, in the embodiment where k=200 ° is preferred, if the k pixel data all belong to the black screen data', the data control circuit 12 4 determines the line drawing 099127822 form. No. A0101 Page 15 of 40 0992048872-0 201209793 Prime 165 is a picture line showing black pictures.

That is, the first part of the random number and the second part of the random number may be partially identical, and thus the first part of the random number corresponds to the kl address address and the second part The k2 addressing addresses corresponding to the random number may have some identical conditions. For example, if the value of each set of random numbers is k = 200, k is 100, k2 = 100, and the random number generator 122 first generates 100 random numbers of the first part, and then generates the second part. 100 random numbers, and the 100 random numbers of the first part may be the same as the 100 random numbers of the second part, so the 100 random numbers of the first part correspond to 10 0 The addressing address corresponding to the random number of the second part may be partially the same, and in the process of reading the 200 pixel data according to the 200 addressing addresses, a corresponding part may occur. The prime data was read and analyzed twice. The random number generator 122 generates each set of random numbers in two or more times, and relatively achieves an effect of making the analysis result of the data control circuit 124 more accurate. [0032] Further, in an embodiment, the data control circuit 124 may analyze each of the k pixel data, if at least 70% of the k pixel data belongs to a white screen. For the data, the line of pixels 165 belongs to the pixel line displaying the white picture. When the data control circuit 124 finds by counting, among the n-line pixels continuously displayed, the m-line pixels continuously displayed display a black picture, n24, n> m22, and at least two lines of other nm lines of pixels are continuously displayed. If the pixel display white screen, the data control circuit 124 controls 099127822 Form No. A0101 Page 16 / Total 40 Page 0992048872-0 201209793 [0034] [0035] Ο [0036] The polarity inversion control circuit 125 is configured The first-polarity reversal control signal is rotated out. Preferably, if the other n pixel data of the η-晴 belongs to the white screen data, the data control circuit 124 controls the polarity inversion control circuit to output the first polarity inversion control signal ^, which is combined with FIG. 1 and FIG. 4 The working principle of the preferred embodiment of the liquid crystal display device of the present invention will be described by taking an image as an example. a low-differential signal connector (not shown) provides -f贞 image data to the timing control circuit 110. Further, the image data is supplied to the scratchpad of the data analysis module 120 121 and the timing control module 130. The image data includes a plurality of rows of pixel data. The random number generator 122 generates a complex array of random numbers corresponding to the plurality of rows of pixel data, wherein each set of random numbers corresponds to one line of stamp data and includes a plurality of addressable addresses. Specifically, the random number generator 122 generates the random number for each group twice. Assuming that the number of random numbers of each group is 2, the random number generator 122 first generates 100 random numbers, and then generates another random number. .

When the number of digits is 200, the data control circuit 124 reads 200 pixel data in the corresponding row of pixel data from the register 121. The capital 099127822 form number ΑΟίοι 17th buy/total 40 pages 0992048872-0 201209793 The material control circuit 124 analyzes the pixel data (such as the 200 morpheme data) read from each line of pixel data to determine the The line element 165 is a black picture data line or a white picture data line to determine whether the image data of the one frame conforms to the "continuously displayed η line pixel 165, and the continuously displayed ra line pixel 165 displays a black picture. N24, n > m22, and at least two rows of other nm pixels are continuously displayed, the pixel 165 displays a white screen. If the result is YES, the data control circuit 124 controls the polarity inversion control circuit 125 to output the The first polarity inversion control signal; if the result is no, the data control circuit 124 controls the polarity inversion control circuit 125 to output f the second polarity inversion control signal. [0037] Further, the data control circuit 124 can also set the values and conditions of η and m, such as setting: the 11=10, 111=5, and the other 11-111 rows of pixels 165 are consecutively displayed pixel rows.

For example, if η = 8, ra = 4, and other nm rows of pixels 1 65 are consecutively displayed, the data control circuit 124 can also set: the image data of the one frame includes continuous display. 8 lines of pixel data, in which 4 lines of continuously displayed pixels 165 display a black picture, and 4 lines of consecutively displayed pixels 165 display a white picture. And when the image of one frame includes the n rows of pixels satisfying the above conditions, the data control circuit 124 controls the polarity inversion control circuit 12.5 to output the first polarity inversion control signal; otherwise, the data control circuit 124 The polarity inversion control circuit 125 is controlled to output the second polarity inversion control signal. [0038] On the other hand, after the timing control module 130 receives the image data of the one frame, 099127822 Form No. 1010101 Page 18/40 pages 0992048872-0 201209793 Data processing of the image data of one frame generates timing signals And the data signal, and the timing signal is provided to the scan driving circuit 150 and the data driving circuit 140 for controlling the working timing, and further supplying the data signal to the data driving circuit 140.
