Description

自發光顯示器之驅動方法、行驅動電路、自發光顯示裝置及資訊處理裝置Driving method of self-luminous display, row driving circuit, self-luminous display device and information processing device

本發明係有關於自發光顯示器，特別是關於一種可提高自發光顯示器之畫面品質之驅動方法。The invention relates to a self-luminous display, in particular to a driving method capable of improving the picture quality of a self-luminous display.

為了避免一自發光顯示器(LED或OLED顯示器)之螢幕產生水波紋現象，所述的水波紋現象係指以一手機拍攝該螢幕時人眼會在該手機的顯示幕上看到抖動的水波紋，現行的自發光顯示器已有利用多幀子畫面合以呈現一幀畫面之顯示效果之設計。由於該設計會提高螢幕刷新率，例如將螢幕刷新率由60Hz提高至240Hz，因此可使刷新週期避開人眼的視覺暫留時間，從而有效降低所述的水波紋現象。In order to avoid the water ripple phenomenon on the screen of a self-luminous display (LED or OLED display), the water ripple phenomenon refers to the shaking water ripples that the human eye will see on the display screen of the mobile phone when shooting the screen with a mobile phone , the current self-luminous display has been designed to combine multiple frames of sub-pictures to present the display effect of one frame. Since this design increases the screen refresh rate, for example, the screen refresh rate is increased from 60 Hz to 240 Hz, so that the refresh cycle can avoid the visual persistence time of human eyes, thereby effectively reducing the above-mentioned water ripple phenomenon.

然而，當螢幕刷新率提高時，每一個自發光元件在各幀子畫面的顯示期間所能分配到的導通時間會大幅縮短，致使各個自發光元件的有效導通時間更容易受到其他自發光元件的驅動電壓信號干擾而影響其發光狀態。請參照圖1，其為一現有共陽LED陣列顯示器之示意圖。如圖1所示，該共陽LED陣列顯示器包括一列驅動器10、一行驅動器20及一共陽LED陣列30，其中，在每一幀子畫面顯示期間，列驅動器10依序輸出一高電位至各列線11以依序致能各列(row) LED 31，而行驅動器20則係在各列掃描期間藉由同時輸出多個電壓脈衝信號至多條行線21以決定各列LED 31中之各個LED 31之導通時間，從而使共陽LED陣列30顯示一幀子畫面，其中，所述電壓脈衝信號包含一下降緣、一固定低電位階段和一上升緣。However, when the refresh rate of the screen is increased, the conduction time allocated to each self-luminous element during the display period of each frame sub-picture will be greatly shortened, so that the effective conduction time of each self-luminous element is more likely to be affected by other self-luminous elements. The driving voltage signal interferes to affect its light emitting state. Please refer to FIG. 1 , which is a schematic diagram of a conventional common anode LED array display. As shown in Figure 1, the common anode LED array display includes a column driver 10, a row driver 20 and a common anode LED array 30, wherein, during the display period of each frame of sub-picture, the column driver 10 sequentially outputs a high potential to each column The line 11 is used to enable each column (row) LED 31 in sequence, and the row driver 20 is to determine each LED in each column LED 31 by simultaneously outputting a plurality of voltage pulse signals to a plurality of row lines 21 during the scanning period of each column. 31 , so that the common anode LED array 30 displays a frame of sub-pictures, wherein the voltage pulse signal includes a falling edge, a fixed low potential stage and a rising edge.

然而，同一列LED 31中之多個LED 31之所述電壓脈衝信號卻會互相串擾而改變各所述電壓脈衝信號的下降緣及/或上升緣的時間，從而影響各LED 31之發光狀態。特別是，預計呈現高亮度的LED 31會經由串擾作用影響預計呈現低亮度的LED 31的發光狀態，致使預計呈現低亮度的LED 31其實際呈現的亮度高於預計的亮度。However, the voltage pulse signals of multiple LEDs 31 in the same row of LEDs 31 will crosstalk each other and change the falling edge and/or rising edge time of each voltage pulse signal, thereby affecting the light-emitting state of each LED 31 . In particular, the LED 31 expected to exhibit high brightness will affect the light-emitting state of the LED 31 expected to exhibit low brightness through crosstalk, so that the LED 31 expected to exhibit low brightness actually exhibits a higher brightness than the expected brightness.

為解決上述的問題，本領域亟需一新穎的自發光顯示器之驅動方法。In order to solve the above problems, there is an urgent need in the art for a novel driving method of self-luminous displays.

依上述的說明，本發明進一步提出一種自發光顯示器之驅動方法。請參照圖4，其為本發明之自發光顯示器之驅動方法之一實施例之流程圖。如圖4所示，該方法包括：將一幀畫面顯示資料分為多幀子畫面顯示資料，並將各幀子畫面顯示資料之各列顯示資料分為一列低灰階成分顯示資料及一列高灰階成分顯示資料，其中，所述低灰階成分顯示資料之數值等於兩個不同整數中之一數值(步驟a)；以及將各列低灰階成分顯示資料及各列高灰階成分顯示資料分別轉成一組第一輸出電流源及一組第二輸出電流源以驅動一自發光元件陣列之一列自發光元件，其中，該組第一輸出電流源的電流值係由一對應的電流增益及/或一對應的PWM脈衝寬度決定(步驟b)。According to the above description, the present invention further provides a driving method of a self-luminous display. Please refer to FIG. 4 , which is a flowchart of an embodiment of the driving method of the self-luminous display of the present invention. As shown in Figure 4, the method includes: dividing one frame of picture display data into multiple frames of sub-picture display data, and dividing each row of display data of each frame of sub-picture display data into a row of low grayscale component display data and a row of high grayscale component display data, wherein the value of the low grayscale component display data is equal to one of two different integer values (step a); and each column of low grayscale component display data and each column of high grayscale component display The data are respectively converted into a group of first output current sources and a group of second output current sources to drive a column of self-luminous elements in a self-luminous element array, wherein the current value of the group of first output current sources is determined by a corresponding current The gain and/or a corresponding PWM pulse width is determined (step b).

在上述的方法中，該幀畫面顯示資料之各列顯示資料分為一第一子列顯示資料及一第二子列顯示資料，其中，各列顯示資料之各像素資料值係依一閾值分成一高灰階成分值和一低灰階成分值，該低灰階成分值為介於0至該閾值之間之一第一整數，該高灰階成分值為各所述像素資料值高於該閾值時扣除該閾值所產生之一第二整數，各所述第一整數歸屬所述第一子列顯示資料，且各所述第二整數歸屬所述第二子列顯示資料。In the above-mentioned method, each column of display data of the frame of picture display data is divided into a first sub-column of display data and a second sub-column of display data, wherein each pixel data value of each column of display data is divided according to a threshold a high grayscale component value and a low grayscale component value, the low grayscale component value is a first integer between 0 and the threshold value, the high grayscale component value is higher than each pixel data value A second integer generated by subtracting the threshold from the threshold, each of the first integers belongs to the first sub-column display data, and each of the second integers belongs to the second sub-column of display data.

另外，所述第一子列顯示資料的數值會對應分配至各幀所述子畫面顯示資料之一列低灰階成分顯示資料中，而所述第二子列顯示資料的數值會對應分配至各幀所述子畫面顯示資料之一列高灰階成分顯示資料中。In addition, the values of the first sub-column display data will be correspondingly assigned to one row of low grayscale component display data of the sub-picture display data in each frame, and the values of the second sub-column display data will be correspondingly distributed to each A row of high grayscale components in the sub-picture display data of the frame is in the display data.

舉例而言，假設所述閾值為119，當像素資料值為10時，低灰階成分值為10，高灰階成分值為0；當像素資料值為119時，低灰階成分值為119，高灰階成分值為0；當像素資料值為120時，低灰階成分值為119，高灰階成分值為1(=120-119)；當像素資料值為200時，低灰階成分值為119，高灰階成分值為81(=200-119)；當像素資料值為2000時，低灰階成分值為119，高灰階成分值為1881(=2000-119)；依此類推。For example, assuming that the threshold value is 119, when the pixel data value is 10, the low grayscale component value is 10, and the high grayscale component value is 0; when the pixel data value is 119, the low grayscale component value is 119 , the high grayscale component value is 0; when the pixel data value is 120, the low grayscale component value is 119, and the high grayscale component value is 1 (=120-119); when the pixel data value is 200, the low grayscale component value The component value is 119, and the high grayscale component value is 81 (=200-119); when the pixel data value is 2000, the low grayscale component value is 119, and the high grayscale component value is 1881 (=2000-119); And so on.

另外，假設一幀畫面係以N幀子畫面等效呈現，N為大於1之整數，則當一像素之低灰階成分值為K時，K為一非負整數，K可表為m*q+r，其中，q為一預定正整數，m為K/q之商，r為K/q之餘數；且該像素在N幀子畫面之第q幀至第q+m-1幀中分配到之像素值為q，在N幀子畫面之第1幀至第q-1幀中共分配到之像素值為r，而r可集中分配到第r幀，或打散在第1幀至第r幀中。例如，N=21，K=20，q=8，則m=2，r=4，該像素在21幀子畫面中之第8、9幀分配到像素值8，且在第4幀中分配到像素值4，或在第1至4幀中各分配到像素值1，或以其他的固定分配方式在第1至4幀中分配像素值4。依此安排，任一幀子畫面在所述低灰階成分顯示期間其各像素只會顯示兩種整數值而大幅降低所述的串擾現象，例如，第1幀之各像素只會顯示1或0，第2幀之各像素只會顯示2或0，第3幀之各像素只會顯示3或0，直至第q-1幀之各像素只會顯示q-1或0；第q至N幀之各像素只會顯示q或0。另外，任一幀子畫面在所述高灰階成分顯示期間其各像素所顯示的亮度數值則可為其自所述高灰階成分值依一預定規則所分配到的數值，其中，該預定規則並不限定是哪種規則，只要N幀子畫面中各對應像素所分配到的數值的總和等於所述高灰階成分值即可。舉例而言，假設N=21，所述高灰階成分值為1881，則21幀子畫面中之對應像素在所述高灰階成分顯示期間所顯示的亮度數值可為(89、89、…、89、101)，亦即先將1881平均分配到21幀子畫面中，再將餘數12分配到其中一幀或多幀中。In addition, assuming that one frame of picture is equivalently presented by N frames of sub-pictures, and N is an integer greater than 1, then when the low grayscale component value of a pixel is K, K is a non-negative integer, and K can be expressed as m*q +r, wherein, q is a predetermined positive integer, m is the quotient of K/q, and r is the remainder of K/q; and the pixel is allocated in the qth frame to the q+m-1th frame of the N frame sub-picture The obtained pixel value is q, and the allocated pixel value is r in the first frame to the q-1th frame of the N-frame sub-picture, and r can be allocated to the rth frame collectively, or dispersed in the first frame to the rth frame in frame. For example, N=21, K=20, q=8, then m=2, r=4, the pixel is allocated to the pixel value 8 in the 8th and 9th frames of the 21-frame sub-screen, and is allocated in the 4th frame to a pixel value of 4, or each of the 1st to 4th frames is assigned to a pixel value of 1, or other fixed allocation methods are used to assign a pixel value of 4 to the 1st to 4th frames. According to this arrangement, each pixel of any frame of sub-picture will only display two integer values during the display period of the low grayscale components, thereby greatly reducing the crosstalk phenomenon. For example, each pixel of the first frame will only display 1 or 0, each pixel in the second frame will only display 2 or 0, each pixel in the third frame will only display 3 or 0, until each pixel in the q-1th frame will only display q-1 or 0; from q to N Each pixel of the frame will only display q or 0. In addition, the luminance value displayed by each pixel of any frame sub-picture during the display period of the high gray-scale component can be the value assigned from the value of the high gray-scale component according to a predetermined rule, wherein the predetermined The rule does not limit what kind of rule it is, as long as the sum of the values assigned to the corresponding pixels in the N frames of sub-pictures is equal to the high grayscale component value. For example, assuming that N=21 and the value of the high grayscale component is 1881, then the luminance value displayed by the corresponding pixel in the 21-frame sub-picture during the display period of the high grayscale component can be (89, 89, . . . , 89, 101), that is, firstly distribute 1881 evenly to 21 sub-frames, and then distribute the remainder 12 to one or more frames.

依上述的設計，各所述第一輸出電流源的電流值即可統一由一對應的電流增益及/或一對應的PWM脈衝寬度決定，從而大幅簡化電流源電路143的電路架構。 例如，針對一特定列之低灰階成分顯示資料而言，假設第1幀子畫面之各像素只會顯示1或0，第2幀子畫面之各像素只會顯示2或0，第3幀子畫面之各像素只會顯示3或0 ，則在顯示第1幀子畫面時，各所述第一輸出電流源的電流值即可統一由一對應的電流增益(G1)及/或一對應的PWM脈衝寬度(W1)決定；在顯示第2幀子畫面時，各所述第一輸出電流源的電流值即可統一由一對應的電流增益(G2)及/或一對應的PWM脈衝寬度(W2)決定；以及在顯示第3幀子畫面時，各所述第一輸出電流源的電流值即可統一由一對應的電流增益(G3)及/或一對應的PWM脈衝寬度(W3)決定；其中，G1、G2、G3係經由像素值1、2、3映射一查找表而得。According to the above design, the current value of each of the first output current sources can be uniformly determined by a corresponding current gain and/or a corresponding PWM pulse width, thereby greatly simplifying the circuit structure of the current source circuit 143 . For example, for the display data of a specific row of low grayscale components, assuming that each pixel of the sub-screen in the first frame can only display 1 or 0, each pixel in the sub-screen of the second frame can only display 2 or 0, and the sub-screen of the third frame can only display 1 or 0. Each pixel of the sub-picture can only display 3 or 0, then when the first frame sub-picture is displayed, the current value of each of the first output current sources can be unified by a corresponding current gain (G1) and/or a corresponding The PWM pulse width (W1) is determined; when displaying the sub-picture of the second frame, the current value of each of the first output current sources can be unified by a corresponding current gain (G2) and/or a corresponding PWM pulse width (W2) decision; and when displaying the 3rd frame sub-picture, the current value of each described first output current source can be unified by a corresponding current gain (G3) and/or a corresponding PWM pulse width (W3) Determine; where, G1, G2, G3 are obtained by mapping pixel values 1, 2, 3 to a look-up table.
