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.

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.

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.

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.

In order to solve the above problems, there is an urgent need in the art for a novel driving method of self-luminous displays.

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).

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.

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.

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.

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.

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.
