Description

Technical Field

[0001] The present application relates to the field of electronic paper driving, and particularly to a driving method for an electronic paper, a driving integrated circuit, and a display panel. Background Art

[0002] During the actual driving process of an electronic paper, both positive and negative voltages are required. Specifically, according to the characteristics of charged particles, the voltage waveform applied during the change from one gray scale to another. Since the driving method of the capsule-type electronic paper is PWM debugging, it is divided into pulse width and positive / negative. As Figure 1 shown, the upper figure is the PWM waveform, that is, the output of the data line. Figure 1 The lower figure in Figure 2 is the gray scale switching process. The gray scale is A, and the target gray scale is B. If the number of effective pulses of gray scale A is M, and the number of effective pulses of gray scale B is N, the number of pulses from pure black to pure white is X. Then the number of pulses from gray scale A to pure black is X - M, and the number of pulses from pure white to the target gray scale B is N. The total number of required pulses is 2X - M + N. The number of positive pulses is X - M + N, and the number of negative pulses is X. The pulse quantities are added with signs: X - M + N - X = N - M. The obtained result N - M is called the effective time of driving. From gray scale A to gray scale B, the effective time is N - M. From gray scale B to A, if it is M - N, it is called DC (Direct Current) balance. However, DC imbalance will cause an afterimage phenomenon. As shown, the display driving is always from black to white first. In this way, within the first cycle, the effective time is N - M, and in the second cycle, it is S - Y. If gray scale A and gray scale B are not equal, the DC will not be balanced, and with the increase of the cycle, the imbalance phenomenon will become more serious.

Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0030] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] In the 1970s, Japan first developed electrophoretic display technology. However, due to many disadvantages such as short display life, instability, and difficulty in colorization of the initially developed ordinary electrophoresis, the experiment was once interrupted. At the end of the 20th century, the American company E - Ink invented electrophoretic ink (also known as electronic ink) using electrophoretic technology, which greatly promoted the development of this technology. Electronic ink is usually made into a film for use in electronic displays, especially for e - books.

[0032] As Figure 3 shown in the electronic ink screen, the electronic ink screen includes a surface layer 1, a transparent electrode 2, a capsule 3, and a lower electrode 7; among them, the components in the capsule 3 are similar to electronic ink. Each capsule 3 contains liquid charges, which include a positively charged white dye 4, a negatively charged black dye 5, and a transparent dispersion medium 6. When positive and negative voltages are applied on one side (support layer 8), the charged liquids will be attracted and repelled respectively, so that each pixel can display white 10 or black 11.

[0033] As Figure 4The overall display part architecture of the electronic paper shown, where the edge sealing part 12 is a capsule; the protective plate 13 is the common voltage terminal; 14 is the transparent dispersion medium; 15 is the transparent electrode; 16 is the thin film transistor (TFT) trace layer; 17 is the substrate; 18 is the driving integrated circuit for outputting data signals and other voltage control signals; 19 is the transmission carrier board for transmitting the signals of the circuit board to the driving integrated circuit; 20 is the driving board.

[0034] As Figure 5 shown in the driving principle of the electronic paper, when the G1 voltage is high, the corresponding TFT is turned on, and the corresponding data line charges the pixel electrode; when the G1 voltage is low, the corresponding TFT is turned off, and the voltage of the pixel electrode is maintained. Taking only black and white as an example, there are only two voltages when the data line is charging, that is, when the corresponding position is white, the charging voltage of the data line is V1; when the corresponding position is black, the charging voltage of the data line is V2; and so on for other pixels. It should be noted that applying an electric field in one direction for a long time or accumulating an electric pulse in one direction for a long time will cause irreversible damage to the electronic capsule.

[0035] Figure 6 is a schematic flowchart of a driving method for an electronic paper provided by an embodiment of the present application. As Figure 6 shown, the steps of this method include:

[0036] Step 601, after the driving integrated circuit of the electronic paper is powered on and receives an input signal, the driving integrated circuit outputs a waveform of the first cycle corresponding to the first frame. Among them, during the process of the input signal driving the generation of the waveform of the first cycle, the pixel color transformation process corresponding to the first frame changes from the first color to the second color;

[0037] In the embodiment of the present application, the first color and the second color can be any one of black and white, but the first color and the second color need to be different, that is, when the first color is black, the second color is white; or when the first color is white, the second color is black.

[0038] Step 602, the driving integrated circuit outputs a waveform of the second cycle corresponding to the second frame. Among them, during the process of the input signal driving the generation of the waveform of the second cycle, the pixel color transformation process corresponding to the second frame changes from the second color to the first color, and the first frame and the second frame are any two adjacent frames driven by the driving integrated circuit.

[0039] In this regard, in a specific example, the second frame can be selected as the next frame of the first frame.

[0040] For the above steps 601 to 602, in a specific example, as Figure 7As shown, from gray scale A to gray scale B and then back to gray scale A, the driving process is gray scale A → black → white → gray scale B → white → black → gray scale A. The effective time within two cycles = -M + X - X + N + X - N - X + M = 0. It can be seen that the DC balance is satisfied. However, as Figure 2 shown in the prior art, from gray scale A to gray scale B and then back to gray scale A, the driving process is gray scale A → black → white → gray scale B → black → white → gray scale A. In the first cycle, the effective time is N - M, and in the second cycle, it is S - Y. If gray scale A and gray scale B are not equal, the DC will not be balanced. Thus, it can be seen that in the embodiments of the present application, through the above steps 601 to 602, the waveforms generated for driving two adjacent frames are different. That is, during the process of the input signal driving the generation of the waveform in the first cycle, the pixel color transformation process corresponding to the first frame changes from the first color to the second color, while during the process of the input signal driving the generation of the waveform in the second cycle, the pixel color transformation process corresponding to the second frame changes from the second color to the first color. Thus, it can be seen that the waveform selections corresponding to two adjacent frames are opposite, so that the waveforms of two adjacent frames can be symmetric. Therefore, the effective time within the two cycles corresponding to two adjacent frames is 0, thereby achieving DC balance and solving the problem of DC imbalance in the prior art for electronic paper, and achieving the effect of improving afterimage.

[0041] In an alternative embodiment of the embodiments of the present application, for the manner of outputting the waveform of the first cycle corresponding to the first frame involved in the above step 601, it may further include:

[0042] Step 11, the color unit in the driving integrated circuit determines the waveform of the first cycle corresponding to the first frame;

[0043] Step 12, the random access memory (RAM) in the driving integrated circuit stores the first target value; wherein, the first target value represents that the pixel color transformation process corresponding to the first frame changes from the first color to the second color;

[0044] Step 13, the driving integrated circuit outputs the waveform of the first cycle corresponding to the first frame based on the first target value.

[0045] For the above steps 11 to 13, in the embodiments of the present application, the waveform of the first cycle corresponding to the first frame determined by the color unit is stored in the RAM. In a specific example, if the pixel color transformation process of the first frame is from black to white during the process of the input signal driving the generation of the waveform of the second cycle, the corresponding first target value can be 1; if the pixel color transformation process of the first frame is from white to black, the corresponding first target value can be 0. That is to say, the target value stored in the RAM is in one-to-one correspondence with the pixel color transformation process of the output frame. In this way, when determining the waveform corresponding to the next frame, through this first target value, it can be determined whether the pixel color transformation process of the output frame corresponding to the waveform of the previous cycle is from black to white or from white to black, and then the pixel color transformation process of the next frame corresponding to the waveform of the next cycle is determined, so that the waveforms corresponding to two adjacent frames are opposite, thereby achieving DC balance. Taking the pixel color transformation process of the first frame corresponding to the waveform of the first cycle as from black to white and the first target value as 1 as an example, the pixel color transformation process of the second frame corresponding to the waveform of the next cycle is from white to black, and the second target value is 0. Of course, the value of the target value and the color change process of the corresponding frame can be set accordingly in combination with the actual situation. For example, if the pixel color transformation process of the first frame corresponding to the waveform of the first cycle is from black to white and the first target value is 0, the pixel color transformation process of the second frame corresponding to the waveform of the next cycle is from white to black, and the second target value is 1.

[0046] In an alternative implementation manner of the embodiments of the present application, for the manner of outputting the waveform of the second cycle based on the second frame involved in the above step 602, it may further include:

[0047] Step 21, the random access memory in the driving integrated circuit feeds back the first target value to the color unit, and the color unit determines that the pixel color transformation process corresponding to the second frame is opposite to the pixel color transformation process corresponding to the first frame represented by the first target value;

[0048] Step 22, the random access memory in the driving integrated circuit stores the second target value; wherein, the second target value represents that the pixel color transformation process corresponding to the second frame is from the second color to the first color;

[0049] Step 23, the driving integrated circuit outputs the waveform of the second cycle corresponding to the second frame.

[0050] After the waveform output corresponding to the first frame is completed through the above steps 21 to 23, the random access memory will feedback a first target value to the color unit to inform whether the pixel color change process corresponding to the first frame of the waveform in the first period is from black to white or from white to black first, so that it can be determined that the pixel color change process corresponding to the second frame of the waveform in the second period is opposite to the pixel color change process corresponding to the first frame. For example, if the first target value is 1, the pixel color transformation process corresponding to the first frame of the waveform in the corresponding first period is from black to white first. After feeding back the first target value to the color unit, the color unit can know from the first target value that the pixel color transformation process corresponding to the first frame is from black to white first. At this time, the pixel color transformation process corresponding to the second frame needs to be set to from white to black first, so as to Figure 7 achieve the opposite waveforms corresponding to adjacent two frames as shown, so that the effective time within two periods is 0, thereby achieving DC balance.

[0051] Corresponding to the above Figure 6 , an embodiment of the present application provides a driving integrated circuit, as Figure 8 shown, the driving integrated circuit includes a microcontroller interface, a color unit and a waveform selection unit;

[0052] Among them, the color unit is used to obtain an input signal through the microcontroller interface and drive the first frame based on the input signal to generate a waveform in the first period. During the process of generating the waveform in the first period by the input signal, the pixel color transformation process corresponding to the first frame changes from a first color to a second color;

[0053] The waveform selection unit is used to receive and output the waveform in the first period;

[0054] The color unit is used to drive the second frame and generate a waveform in the second period after outputting the waveform in the first period. During the process of generating the waveform in the second period by the input signal, the pixel color transformation process corresponding to the second frame changes from the second color to the first color;

[0055] The waveform selection unit is used to receive and output the waveform in the second period, where the first frame and the second frame are any adjacent two frames output by the driving integrated circuit.

[0056] Through the driving integrated circuit according to the embodiments of the present application, during the process of the input signal driving to generate a waveform of the first period, the pixel color transformation process corresponding to the first frame is from the first color to the second color, while during the process of the input signal driving to generate a waveform of the second period, the pixel color transformation process corresponding to the second frame is from the second color to the first color. It can be seen that the waveform selections corresponding to two adjacent frames are opposite, so that the waveforms of two adjacent frames can be symmetric. Therefore, the effective time within two periods corresponding to two adjacent frames is 0, so as to achieve DC balance, thereby solving the problem of DC imbalance of electronic paper in the prior art.

[0057] In an alternative embodiment of the embodiments of the present application, as Figure 9 shown, the driving integrated circuit in the embodiments of the present application further includes a random access memory;

[0058] Wherein, when the color unit determines that the pixel color transformation process corresponding to the first frame is from the first color to the second color, the random access memory is used to store a first target value; wherein, the first target value represents that the pixel color transformation process corresponding to the first frame is from the first color to the second color;

[0059] The random access memory is further used to feedback the first target value to the color unit before driving the second frame and generating a waveform of the second period.

[0060] When the color unit determines the waveform of the second period corresponding to the second frame, the random access memory is used to store a second target value; wherein, the second target value represents that the pixel color transformation process corresponding to the second frame is from the second color to the first color;

[0061] The random access memory is further used to feedback the second target value to the color unit before driving the third frame and generating a waveform of the third period.

[0062] It can be seen that in the embodiment of the present application, the random access memory stores the pixel color change process corresponding to the first frame corresponding to the waveform of the first period determined by the color unit. In a specific example, if the pixel color change process corresponding to the first frame is from black to white first, the corresponding first target value can be 1. If the pixel color change process corresponding to the first frame is from white to black first, the corresponding first target value can be 0. It can be seen that the target value stored in the random access memory corresponds one-to-one with the pixel color change process corresponding to the output frame. In this way, when determining the pixel color change process corresponding to the output frame corresponding to the waveform of the next period, the first target value can be used to determine whether the pixel color change process corresponding to the output frame corresponding to the waveform of the previous period is from black to white or from white to black first, and then determine the pixel color change process corresponding to the output frame corresponding to the waveform of the next period, so that the waveforms corresponding to two adjacent frames are opposite, thereby achieving DC balance.

[0063] In an alternative embodiment of the embodiment of the present application, the driving integrated circuit further includes a gate buffer and a source buffer;

[0064] Among them, the gate buffer is used to drive the scanning line to drive the scanning signal. The source buffer is used to drive the data line to drive the data signal and output a waveform.

[0065] It can be seen that the gate buffer and the source buffer in the embodiment of the present application are units for increasing the driving capabilities of the data line and the scanning line.

[0066] The present application will be explained and illustrated below in conjunction with the specific implementation manners of the embodiment of the present application. As Figure 10 shown, this specific embodiment provides a driving integrated circuit (Driver IC, DIC). Among them, a black-and-white selection unit (that is, the selection of the pixel color change process of the output frame can be from black to white or from white to black) and a random access memory are added to the driving integrated circuit compared with the prior art. The random access memory is used to store data.

[0067] Based on Figure 10, in a specific example, the working process of the driving integrated circuit is as follows: after the driving integrated circuit is powered on, the microcontroller unit (MCU) receives the input signal input. For the first frame generated by driving the current input signal, the black-and-white unit can randomly select that the color transformation process of the pixels corresponding to the first frame is first black then white, or first white then black. If the black-and-white unit selects that the color transformation process of the pixels corresponding to the first frame is first black then white in the first frame, it simultaneously feeds back the T signal to the random access memory, and the T signal is high, then the data stored in the random access memory is 1; at this time, the gate signal output (data output) outputs the waveform of the first cycle; at the beginning of the second frame, the random access memory transfers 1 to the black-and-white unit, then the black-and-white unit selects the result of first white then black for the waveform selection unit, and simultaneously feeds back the T signal to the random access memory, and the T signal is low, then the data stored in the random access memory is 0; at this time, the gate signal outputs the waveform of the second cycle. At the beginning of the third frame, the random access memory transfers 0 to the black-and-white unit, then the black-and-white unit selects first black then white for the waveform selection unit, and simultaneously feeds back the T signal to the random access memory and the T signal is high, then the data stored in the random access memory is 1; and so on in a cycle to achieve the cyclic output of the adjacent waveforms as described above.

[0068] It can be seen from this that the waveforms corresponding to two adjacent frames are opposite, so as to achieve DC balance, that is, DC balance can be achieved for any two adjacent cycles, then DC imbalance can be achieved for the entire time period, thus achieving the effect of removing the ghosting phenomenon.

[0069] In an alternative embodiment of the embodiment of the present application, there is also a display panel, and the display panel includes the above-mentioned driving integrated circuit.
