Description
本發明是有關於一種編碼方法，特別是指一種用於顯示資料的資料編碼方法及編碼器。The invention relates to an encoding method, in particular to a data encoding method and an encoder for displaying data.
由於科技的迅速發展，顯示裝置的傳輸介面從早期並行傳輸介面的電晶體－電晶體邏輯（Transistor-Transistor Logic, TTL）/互補式金屬氧化物半導體(Complementary Metal-Oxide-Semiconductor, CMOS)訊號，發展到串行傳輸介面的低擺幅差分訊號(Reduced Swing Differential Signal, RSDS)、低電壓差分訊號（Low-Voltage Differential Signaling, LVDS），再到現有的對等式網路（peer-to-peer, P2P）技術，顯示裝置傳輸速度逐年遽增。Due to the rapid development of technology, the transmission interface of the display device has changed from the early parallel transmission interface of transistor-transistor logic (TTL) / Complementary Metal-Oxide-Semiconductor (CMOS) signals, Developed to low-swing differential signal (RSDS), low-voltage differential signal (LVDS) of serial transmission interface, and then to the existing peer-to-peer network (peer-to-peer , P2P) technology, the transmission speed of display devices is increasing year by year.
然而，現有顯示裝置因為資料編碼的複雜度過高，造成電磁干擾(Electromagnetic Interference, EMI)及功率消耗過大。現有的顯示裝置儲存有顯示資料，該顯示資料包含多個像素，每一像素包括多個子像素，每一子像素具有多個位元(bit)，現有的編碼方式是將每一像素個別編碼，亦即將同一像素的同一子像素的該等位元排列在一起。參閱圖1，舉例來說，每一像素包括3個子像素，分別為紅色子像素(R)、綠色子像素(G)、藍色子像素(B)，每一子像素有M個位元，假設該等像素的第一個像素及相鄰的第二個像素相同，若M=8，該第一個像素或該第二個像素表示為10101010 10101010 10101010時，當傳輸該第一個像素或該第二個像素時，位元的翻轉次為21次，而當傳輸該第一個像素及該第二個像素時，則位元的翻轉次為42次，由此可知，即使該第一個像素與該第二個像素相同，該顯示裝置的傳輸介面在傳輸該第一個像素及該第二個像素時，在傳輸該第一個像素及該第二個像素時，需要2倍的位元翻轉次數，使得該顯示裝置的傳輸介面在傳輸該等像素的位元翻轉次數過高，而造成電磁干擾及功率消耗過大。However, the existing display device has too high complexity of data encoding, which causes electromagnetic interference (Electromagnetic Interference, EMI) and excessive power consumption. Existing display devices store display data. The display data includes multiple pixels, each pixel includes multiple sub-pixels, and each sub-pixel has multiple bits. The current encoding method is to encode each pixel individually. That is, the bits of the same sub-pixel of the same pixel are arranged together. Referring to FIG. 1, for example, each pixel includes 3 sub-pixels, namely a red sub-pixel (R), a green sub-pixel (G), and a blue sub-pixel (B), each sub-pixel has M bits, Assuming that the first pixel of these pixels is the same as the adjacent second pixel, if M = 8, the first pixel or the second pixel is represented as 10101010 10101010 10101010, when the first pixel or In the second pixel, the number of bit inversions is 21, and when the first pixel and the second pixel are transmitted, the number of bit inversions is 42, which shows that even the first Pixels are the same as the second pixel, and when the transmission interface of the display device transmits the first pixel and the second pixel, when transmitting the first pixel and the second pixel, it needs 2 times The number of bit flips makes the transmission interface of the display device transmit the pixels with a bit flip number that is too high, causing electromagnetic interference and excessive power consumption.

以下說明本發明資料編碼方法的該第一實施例。The first embodiment of the data encoding method of the present invention will be described below.
在步驟201中，該編碼模組11編排該第一像素的第1個子像素的該等位元及該第二像素的第1個子像素的該等位元，也就是i=1。In step 201, the encoding module 11 arranges the bits of the first sub-pixel of the first pixel and the bits of the first sub-pixel of the second pixel, that is, i = 1.
在步驟202中，該編碼模組11編排該第一像素的該等子像素的第1個位元及該第二像素的該等子像素的第1個位元，也就是j=1。In step 202, the encoding module 11 arranges the first bit of the sub-pixels of the first pixel and the first bit of the sub-pixels of the second pixel, that is, j = 1.
在步驟203中，該編碼模組11將該第二像素的第i個子像素的第j個位元編排到該第一像素的第i個子像素的第j個位元旁。In step 203, the encoding module 11 arranges the j-th bit of the i-th sub-pixel of the second pixel next to the j-th bit of the i-th sub-pixel of the first pixel.
在步驟204中，該編碼模組11判定該第一像素的第i個子像素的第j個位元及該第二像素的第i個子像素的第j個位元是否為第M個位元，亦即判定是否j=M。當該編碼模組11判定出該第一像素的第i個子像素的第j個位元及該第二像素的第i個子像素的第j個位元不為第M個位元時，流程進行步驟205。當該編碼模組11判定出該第一像素的第i個子像素的第j個位元及該第二像素的第i個子像素的第j個位元為第M個位元時，流程進行步驟206。In step 204, the encoding module 11 determines whether the j-th bit of the i-th sub-pixel of the first pixel and the j-th bit of the i-th sub-pixel of the second pixel are M-th bit, That is to say whether j = M. When the encoding module 11 determines that the j-th bit of the i-th sub-pixel of the first pixel and the j-th bit of the i-th sub-pixel of the second pixel are not the M-th bit, the flow proceeds Step 205. When the encoding module 11 determines that the j-th bit of the i-th sub-pixel of the first pixel and the j-th bit of the i-th sub-pixel of the second pixel are the M-th bit, the process proceeds to steps 206.
在步驟205中，該編碼模組11編排該第一像素的第i個子像素的第(j+1)個位元及該第二像素的第i個子像素的第(j+1)個位元，亦即將j設為j+1。之後，重複步驟203~204直到j=M。In step 205, the encoding module 11 arranges the (j + 1) th bit of the i-th subpixel of the first pixel and the (j + 1) th bit of the i-th subpixel of the second pixel , That is, j is set to j + 1. Thereafter, steps 203 to 204 are repeated until j = M.
在步驟206中，該編碼模組11判定該第一像素的第i個子像素及該第二像素的第i個子像素是否為第N個子像素，亦即判定是否i=N。當該編碼模組11判定出該第一像素的第i個子像素及該第二像素的第i個子像素不為第N個子像素時，流程進行步驟207。當該編碼模組11判定出該第一像素的第i個子像素及該第二像素的第i個子像素為第N個子像素時，流程結束。In step 206, the encoding module 11 determines whether the i-th sub-pixel of the first pixel and the i-th sub-pixel of the second pixel are N-th sub-pixels, that is, whether i = N is determined. When the encoding module 11 determines that the i-th sub-pixel of the first pixel and the i-th sub-pixel of the second pixel are not the N-th sub-pixel, the flow proceeds to step 207. When the encoding module 11 determines that the i-th sub-pixel of the first pixel and the i-th sub-pixel of the second pixel are N-th sub-pixels, the process ends.
在步驟207中，該編碼模組11編排該第一像素的第(i+1)個子像素及該第二像素的第(i+1)個子像素，亦即將i設為i+1。之後，重複步驟202~206直到i=N。In step 207, the encoding module 11 arranges the (i + 1) th subpixel of the first pixel and the (i + 1) th subpixel of the second pixel, that is, i is set to i + 1. After that, steps 202 ~ 206 are repeated until i = N.
參閱圖4，舉例來說，假設M=8，N=3，即每一像素包括3個子像素，即紅色子像素、綠色子像素，及藍色子像素，每一子像素具有8個位元，假設該第一像素及該第二像素相同，且該第一像素或該第二像素的位元可個別地表示為10101010 10101010 10101010，當在傳輸該第一像素及該第二像素時，位元翻轉次數為42，在經過步驟201~207的編碼後，該第一像素或該第二像素的位元可個別地表示為1100110011001100 1100110011001100 1100110011001100，在傳輸該第一像素及該第二像素時，位元翻轉次數為21，由此可知相較於現有的編碼方法，在傳輸該第一像素及該第二像素只需要較低的(一半)位元翻轉次數。Referring to FIG. 4, for example, assuming M = 8 and N = 3, that is, each pixel includes 3 sub-pixels, that is, red sub-pixel, green sub-pixel, and blue sub-pixel, each sub-pixel has 8 bits , Assuming that the first pixel and the second pixel are the same, and the bits of the first pixel or the second pixel can be individually expressed as 10101010 10101010 10101010, when transmitting the first pixel and the second pixel, the bit The number of cell inversions is 42. After encoding in steps 201 to 207, the bits of the first pixel or the second pixel can be individually expressed as 1100110011001100 1100110011001100 1100110011001100. When transmitting the first pixel and the second pixel, The number of bit flips is 21, which shows that compared to the existing encoding method, only a lower (half) number of bit flips is required to transmit the first pixel and the second pixel.
值得注意的是，在本第一實施例中，該編碼模組11係編排該第一像素及該第二像素的所有子像素的所有位元，例如編排紅色子像素的所有位元、綠色子像素的所有位元，及藍色子像素的所有位元，在其他實施例中，該編碼模組11亦可只編排該第一像素及該第二像素的第一個子像素的所有位元，例如只編排紅色子像素的所有位元，但不以此為限。It is worth noting that in the first embodiment, the encoding module 11 arranges all the bits of all sub-pixels of the first pixel and the second pixel, for example, arranges all the bits of the red sub-pixel and the green sub-pixel All the bits of the pixel and all the bits of the blue sub-pixel. In other embodiments, the encoding module 11 may only arrange all the bits of the first sub-pixel of the first pixel and the second pixel , For example, only arrange all the bits of the red sub-pixel, but not limited to this.
要再注意的是，在本第一實施例中，該編碼模組11係將該第一像素及該第二像素編碼，在其他實施例中，當該顯示資料包括多個像素時，該編碼模組11可以將該等像素兩兩編碼，例如該顯示資料包括6個像素，該編碼模組11將第1個像素及第2個像素編碼，並將第3個像素及第4個像素編碼，再將第5個像素及第6個像素編碼，且該編碼模組11可以將多個像素一起編碼，例如該顯示資料包括6個像素，該編碼模組11將第1個像素、第2個像素及第3個像素編碼，並將第4個像素、第5個像素及第6個像素編碼，且若越多像素一起編碼，位元翻轉次數越低，但不限於此。It should be further noted that in the first embodiment, the encoding module 11 encodes the first pixel and the second pixel. In other embodiments, when the display data includes multiple pixels, the encoding The module 11 can encode the pixels in pairs. For example, the display data includes 6 pixels. The encoding module 11 encodes the first pixel and the second pixel, and encodes the third pixel and the fourth pixel. , And then encode the fifth pixel and the sixth pixel, and the encoding module 11 can encode multiple pixels together, for example, the display data includes 6 pixels, the encoding module 11 encodes the first pixel, the second Pixels and the third pixel are encoded, and the fourth pixel, the fifth pixel and the sixth pixel are encoded, and if more pixels are encoded together, the number of bit flips is lower, but not limited to this.

The second embodiment of the encoder 1 is similar to the first embodiment, except that the encoding module 11 is used to arrange the first bit of the first sub-pixel of the second pixel to Next to the first bit of the first sub-pixel of the first pixel, and then arrange the first bit of the next sub-pixel of the second pixel to the first bit of the next sub-pixel of the first pixel Next to the bit, the first bit of the next sub-pixel of the second pixel is repeatedly arranged until the first bit of the last sub-pixel of the second pixel is arranged to the last sub-pixel of the first pixel Next to the first bit of the first pixel, and the encoding module 11 also arranges the next bit of the first sub-pixel of the second pixel to the next bit of the first sub-pixel of the first pixel, And then arrange the next bit of the next sub-pixel of the second pixel next to the next bit of the next sub-pixel of the first pixel, and repeatedly arrange the next bit of the next sub-pixel of the second pixel Cells until the next bit of the last sub-pixel of the second pixel is arranged to the first Next to the next bit of the last sub-pixel of the pixel, the next bit of each sub-pixel of the second pixel is repeatedly arranged until the last bit of the last sub-pixel of the second pixel is arranged to the Next to the last bit of the last sub-pixel of a pixel.

在步驟304中，該編碼模組11判定該第一像素的第i個子像素及該第二像素的第i個子像素是否為第N個子像素，亦即判定是否i=N。當該編碼模組11判定出該第一像素的第i個子像素及該第二像素的第i個子像素不為第N個子像素時，流程進行步驟305。當該編碼模組11判定出該第一像素的第i個子像素及該第二像素的第i個子像素為第N個子像素時，流程進行步驟306。In step 304, the encoding module 11 determines whether the i-th sub-pixel of the first pixel and the i-th sub-pixel of the second pixel are N-th sub-pixels, that is, whether i = N is determined. When the encoding module 11 determines that the i-th sub-pixel of the first pixel and the i-th sub-pixel of the second pixel are not N-th sub-pixels, the process proceeds to step 305. When the encoding module 11 determines that the i-th sub-pixel of the first pixel and the i-th sub-pixel of the second pixel are N-th sub-pixels, the process proceeds to step 306.
在步驟305中，該編碼模組11編排該第一像素的第(i+1)個子像素及該第二像素的第(i+1)個子像素，亦即將i設為i+1。之後，重複步驟303~304直到i=N。In step 305, the encoding module 11 arranges the (i + 1) th subpixel of the first pixel and the (i + 1) th subpixel of the second pixel, that is, i is set to i + 1. After that, steps 303 ~ 304 are repeated until i = N.
在步驟306中，該編碼模組11判定該第一像素的第i個子像素的第j個位元及該第二像素的第i個子像素的第j個位元是否為第M個位元，亦即判定是否j=M。當該編碼模組11判定出該第一像素的第i個子像素的第j個位元及該第二像素的第i個子像素的第j個位元不為第M個位元時，流程進行步驟307。當該編碼模組11判定出該第一像素的第i個子像素的第j個位元及該第二像素的第i個子像素的第j個位元為第M個位元時，流程結束。In step 306, the encoding module 11 determines whether the j-th bit of the i-th sub-pixel of the first pixel and the j-th bit of the i-th sub-pixel of the second pixel are M-th bit, That is to say whether j = M. When the encoding module 11 determines that the j-th bit of the i-th sub-pixel of the first pixel and the j-th bit of the i-th sub-pixel of the second pixel are not the M-th bit, the flow proceeds Step 307. When the encoding module 11 determines that the j-th bit of the i-th sub-pixel of the first pixel and the j-th bit of the i-th sub-pixel of the second pixel are M-th bit, the flow ends.
在步驟307中，該編碼模組11編排該第一像素的第i個子像素的第(j+1)個位元及該第二像素的第i個子像素的第(j+1)個位元，亦即將j設為j+1。之後，重複步驟302~306直到j=M。In step 307, the encoding module 11 arranges the (j + 1) th bit of the i-th subpixel of the first pixel and the (j + 1) th bit of the i-th subpixel of the second pixel , That is, j is set to j + 1. After that, steps 302 ~ 306 are repeated until j = M.
值得注意的是，在本第二實施例中，該編碼模組11係編排該第一像素及該第二像素的所有子像素的所有位元，例如編排紅色子像素的所有位元、綠色子像素的所有位元，及藍色子像素的所有位元，在其他實施例中，該編碼模組11亦可只編排該第一像素及該第二像素的所有子像素之第一個位元，例如只編排紅色子像素的第1個位元、綠色子像素的第1個位元，及藍色子像素的第1個位元，但不以此為限。It is worth noting that in the second embodiment, the encoding module 11 arranges all the bits of all the sub-pixels of the first pixel and the second pixel, for example, arranges all the bits of the red sub-pixel and the green All bits of the pixel and all bits of the blue sub-pixel. In other embodiments, the encoding module 11 may also arrange only the first bit of all sub-pixels of the first pixel and the second pixel For example, only the first bit of the red sub-pixel, the first bit of the green sub-pixel, and the first bit of the blue sub-pixel are arranged, but not limited to this.
綜上所述，本發明資料編碼方法及編碼器，藉由該編碼模組11將相鄰像素的同一位置的子像素的同一位置的位元編排在一起，藉此降低傳輸像素時的位元翻轉次數，以達到降低電磁干擾及功率消耗的功效，故確實能達成本發明的目的。In summary, in the data encoding method and encoder of the present invention, the encoding module 11 arranges the bits at the same position of the sub-pixels of the same position of adjacent pixels together, thereby reducing the bit when transmitting pixels The number of flips is to achieve the effect of reducing electromagnetic interference and power consumption, so it can indeed achieve the purpose of cost invention.
