Example 1
The embodiment of the disclosure provides a driving method of an electrophoretic display pixel. The driving method of the present disclosure is used to drive an electrophoretic display pixel. The electrophoretic display pixel comprises a pixel circuit, a pixel electrode, a common electrode and electrophoretic particles. The output end of the pixel circuit is connected with the pixel electrode, the pixel electrode and the common electrode are oppositely arranged and can generate a driving electric field, and the electrophoretic particles are accommodated between the pixel electrode and the common electrode and move under the driving electric field. Fig. 1 schematically illustrates a driving method of an electrophoretic display pixel according to an embodiment of the present disclosure. As shown in fig. 1, the driving method of the electrophoretic display pixel includes:
Step S110, obtaining a target gray value of an electrophoretic display pixel, determining a target pulse width according to the size of the target gray value, and generating a single pulse data signal according to the target pulse width; the single pulse data signal is used for driving the electrophoretic particles to move to the target position in the pulse duration of the single pulse data signal so as to enable the electrophoretic display pixels to display as target gray values;
step S120, determining a single pulse scanning signal according to the single pulse data signal, wherein the single pulse scanning signal is used for conducting the input end and the output end of the pixel circuit within the pulse duration time of the single pulse scanning signal;
step S130, outputting a single pulse data signal to the input terminal of the pixel circuit, and outputting a single pulse scan signal to the control terminal of the pixel circuit, so as to conduct the input terminal and the output terminal of the pixel circuit.
The driving method of the electrophoresis display pixel of the scheme of the disclosure determines a target pulse width according to the size of a target gray value, and generates a single pulse data signal according to the target pulse width; and determining a single pulse scanning signal according to the single pulse data signal, outputting the single pulse data signal to the input end of the pixel circuit, and outputting the single pulse scanning signal to the control end of the pixel circuit, so that the single pulse scanning signal is output to the pixel electrode to drive the electrophoretic particles to move to the target position within the pulse duration time of the single pulse data signal, and the electrophoretic display pixel is enabled to display the target gray value. It can be understood that the electrophoretic particles can be driven to move to the target position within the pulse duration of the single pulse data signal by only performing single pulse output of the single pulse scanning signal and the single pulse data signal once, so that the driving display of the electrophoretic display pixels is realized, the signal frequencies of the scanning signal and the data signal can be reduced, and the power consumption of the pixel scanning display process can be reduced.
In some implementations, referring to fig. 2, fig. 2 schematically illustrates a schematic structure of an electrophoretic display pixel according to an embodiment of the disclosure. The electrophoretic pixel structure includes a pixel circuit 210, a pixel electrode 220, a common electrode 230, and electrophoretic particles. The output terminal 213 of the pixel circuit 210 is connected to the pixel electrode 220, and the pixel electrode 220 and the common electrode 230 are disposed opposite to each other and are capable of generating a driving electric field, and the electrophoretic particles are accommodated between the pixel electrode 220 and the common electrode 230 and move under the driving electric field.
Specifically, the electrophoretic display pixel 200 may be a pixel for performing pixel display using an electrophoretic display technology, such as an electronic paper pixel. The electrophoretic particles may be polymer particles, charged particles, or the like. For example, an electrophoretic display pixel may comprise electrophoretic capsules, each having a liquid charge, i.e. electrophoretic particles, therein. Wherein the positively charged particles are white and the negatively charged particles are black. At this time, positive and negative voltages are applied to the pixel electrode and the common electrode, respectively, and the charged particles are attracted and repelled, respectively, so that the electrophoretic display pixel displays a corresponding gray value.
In some implementations, referring to fig. 3, fig. 3 schematically illustrates a schematic diagram of pulse timing of a single pulse scan signal and a single pulse data signal according to an embodiment of the disclosure. As shown in fig. 3, the pulse start time of the single pulse scan signal Gj and the pulse end time of the single pulse data signal Si are the same. Thus, when the pulse of the single pulse scan signal Gj starts, the pixel circuit 210 is turned on for the pulse duration of the single pulse scan signal Gj, the single pulse data signal Si may be input into the pixel electrode 220 through the pixel circuit 210, and the electrophoretic particles are driven to move to the target position for the pulse duration of the single pulse data signal Si, so that the electrophoretic display pixel 200 is displayed as the target gray value. Therefore, the display of a certain electrophoretic display pixel in a certain frame of picture can be realized by a single pulse, and compared with the scheme that the display of a certain electrophoretic display pixel in a certain frame of picture can be realized by a multi-pulse signal at a time, the motion time of the electrophoretic particles can be included in the pulse duration of a single-pulse data signal, and the frequencies of a scanning signal and a data signal can be reduced. While the power consumption w= (1/2) fCV according to parasitic capacitance 2 Wherein f is the signal frequency, V is the signal voltage, and C is the capacitance value of the parasitic capacitance, it can be known that the electrical loss caused by the parasitic capacitance is correspondingly reduced, and further the power consumption required in the picture display refreshing process can be reduced.
The pulse of the single pulse scanning signal Gj may be a positive pulse or a negative pulse, and the present disclosure is not limited thereto. The pulse of the single pulse data signal Si may be a positive pulse or a negative pulse, which is not particularly limited in the present disclosure.
In some implementations, referring to fig. 4, fig. 4 schematically illustrates a specific flowchart of determining a single pulse scanning signal according to a single pulse data signal in an embodiment of the disclosure. As shown in fig. 4, determining the single pulse scan signal according to the single pulse data signal in step S120 may include:
step S410, a first preset duration is adjusted backwards according to the pulse starting time of the single pulse data signal to obtain a first time;
step S420, the first time is taken as the pulse starting time of the single pulse scanning signal;
step S430, a second preset duration is adjusted forward according to the pulse end time of the single pulse data signal to obtain a second time;
In step S440, the second time is taken as the pulse end time of the single pulse scanning signal.
The first preset duration and the second preset duration are smaller than the pulse duration of the single pulse data signal.
In some implementations, referring to fig. 5, fig. 5 schematically illustrates a pulse timing diagram of a single pulse scan signal and a single pulse data signal according to another embodiment of the present disclosure. As shown in fig. 5, the pulse start time of the single pulse scan signal Gj is later than the pulse start time of the single pulse data signal Si by a first preset period. In a specific embodiment, the first preset duration may be much smaller than the pulse duration of the single pulse data signal Si. The pulse end time of the single pulse scan signal Gj is earlier than the pulse end time of the single pulse data signal Si by a second preset duration. In a specific embodiment, the second preset duration may be much smaller than the pulse duration of the single pulse data signal Si. Thus, when the pixel circuit is turned on by the single pulse scanning signal, the pixel circuit and the pixel electrode can be prevented from reading an erroneous data signal, and erroneous display of pixels can be prevented.
In some embodiments, determining the single pulse scan signal from the single pulse data signal of step S120 may include:
Taking the pulse starting time of the single pulse data signal as the pulse starting time of the single pulse scanning signal;
taking the pulse end time of the single pulse data signal as the pulse end time of the single pulse scanning signal;
the pulse starting time of the single pulse data signal is adjusted forwards for a third preset duration;
and (3) backward adjusting the pulse starting time of the single pulse data signal by a fourth preset duration.
The third preset duration and the fourth preset duration are smaller than the pulse duration of the single pulse scanning signal.
Referring to fig. 6, fig. 6 schematically shows a pulse timing diagram of a single pulse scan signal and a single pulse data signal according to still another embodiment of the present disclosure. As shown in fig. 6, the pulse start time of the single pulse data signal Si is earlier than the pulse start time of the single pulse scan signal Gj by a third preset period. In a specific embodiment, the third preset duration may be much smaller than the pulse duration of the single pulse scanning signal Gj, that is, the third preset duration is an order of magnitude smaller than the pulse duration of the single pulse scanning signal Gj. The pulse end time of the single pulse data signal Si is later than the pulse end time of the single pulse scan signal Gj by a fourth preset duration. In a specific embodiment, the fourth preset duration may be much smaller than the pulse duration of the single pulse scanning signal Gj, that is, the fourth preset duration is an order of magnitude smaller than the pulse duration of the single pulse scanning signal Gj. Thus, when the pixel circuit is turned on by the single pulse scanning signal, the pixel circuit and the pixel electrode can be prevented from reading an erroneous data signal, and erroneous display of pixels can be prevented. Moreover, the pulse duration of the single pulse scanning signal and the pulse duration of the single pulse data signal can be ensured to be enough, so that enough electrophoretic particles can be enabled to move to a target gray value, and display errors of the gray value of the electrophoretic display pixel are avoided.
In some implementations, referring to fig. 7, fig. 7 schematically illustrates a specific flowchart of determining a single pulse scanning signal according to a single pulse data signal in an embodiment of the disclosure. As shown in fig. 7, determining the single pulse scan signal according to the single pulse data signal in step S120 may include:
step S710, obtaining the maximum pulse width of the single pulse data signal corresponding to the target gray value when the target gray value takes the maximum value or the minimum value;
in step S720, the maximum pulse width is used as the pulse width of the single pulse scanning signal, and the single pulse scanning signal is determined according to the pulse width of the single pulse scanning signal.

Thereby, display driving for the display array can be achieved by the single pulse scan signal and the single pulse data signal.
As shown in fig. 10, the maximum pulse width of the single pulse data signal corresponding to each pixel in the same row of pixels may be used as the pulse width of the single pulse scanning signal for the pixel in the row. That is, the pulse width of each single pulse scan signal may be different. In this way, the pulse duration of the single pulse scanning signal can be ensured, and the pulse duration of the single pulse data signal can be covered, so that the correct display of the pixels is ensured. When the maximum pulse width of the single pulse data signal corresponding to each pixel in a certain row of pixels is small, the pulse width of the single pulse scanning signal of the row of pixels is also small, so that the picture refresh frequency of the display area array can be increased.
It is noted that the single pulse scan signal and the single pulse data signal described in the present disclosure are single pulse signals that can realize one display of a single pixel. Although the first, second, and third single pulse data signals S1, S2, and S3 in fig. 9 and 10 have a plurality of pulses in form, this is generated by aggregating single pulse data signals of a plurality of pixels onto one signal line. For a single pixel, the display of the sub-pixel is still achieved by a single pulse.
In some implementations, referring to fig. 11, fig. 11 schematically illustrates a specific flowchart of determining a target pulse width according to a magnitude of a target gray value in an embodiment of the disclosure. As shown in fig. 11, determining the target pulse width according to the magnitude of the target gray value in step S110 may include:
step S1110, obtaining the current gray value of the electrophoresis display pixel;
step S1120, determining a gray difference value according to the size of the target gray value and the size of the current gray value;
in step S1130, the target pulse width is determined according to the gray scale difference.
In this way, the display driving can be performed on the pixels in accordance with the display of the current gradation value, that is, the display driving can be performed on the electrophoretic particles of the pixels in accordance with the current state of the electrophoretic particles. It can be understood that, many times, the gray scale change frequency of the display screen is slow, that is, the gray scale value of a pixel of the previous frame of screen may be similar to the gray scale value of the pixel of the current frame of screen, so that longer particle moving time caused by resetting and redrying electrophoretic particles can be saved, and display responsiveness and screen refreshing frequency can be improved.
Illustratively, determining the target pulse width according to the magnitude of the target gray value in step S110 may include:
The target pulse width of the single pulse data signal is determined according to the particle material of the electrophoretic particles of the electrophoretic display pixel and the size of the target gray value.
In particular, the particle movement velocity of the particle material under a driving electric field of a certain preset voltage may be obtained from the particle material of the electrophoretic particles of the electrophoretic display pixel. The pulse voltage of the single pulse data signal may be set to the preset voltage. Then, a target pulse width of the single pulse data signal is determined according to the particle movement speed and the magnitude of the target gray value.
Illustratively, the target pulse width of the single pulse data signal Si has a negative correlation with the particle movement velocity of the electrophoretic particles of the particle material under the driving electric field; the target pulse width of the single pulse data signal Si has a positive correlation with the magnitude of the target gray value.
In some embodiments, referring to fig. 12, fig. 12 schematically illustrates a specific flowchart for determining a target pulse width of a single pulse data signal according to a particle material of an electrophoretic particle of an electrophoretic display pixel and a size of a target gray value in an embodiment of the disclosure. As shown in fig. 12, determining the target pulse width of the single pulse data signal according to the particle material of the electrophoretic particles of the electrophoretic display pixel and the magnitude of the target gray value in the above step may include:
Step S1210, determining the target particle number of the electrophoresis particles to be moved to the target position according to the target gray value;
in step S1220, a target pulse width required for the electrophoretic particles of the target molecular weight to move to the target position is determined according to the target particle number and the particle material of the electrophoretic particles.
Thus, a target pulse width required for the electrophoretic particles of the target molecular weight to move to the target position can be determined according to the number of target particles and the particle material of the electrophoretic particles, so that the electrophoretic particles with template particle data move to the target position within the pulse duration of the single pulse data signal, and the electrophoretic display pixels are displayed as target gray values.

It can be understood that the electrophoretic particles can be driven to move to the target position within the pulse duration of the single pulse data signal by only performing single pulse output of the single pulse scanning signal and the single pulse data signal once, so that the driving display of the electrophoretic display pixels is realized, the signal frequencies of the scanning signal and the data signal can be reduced, and the power consumption of the pixel scanning display process can be reduced.
