Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0031] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., may be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring aspects of this disclosure.

[0032] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0033] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0034] The multi-electrode pixel structure of this application embodiment can be applied to display devices, particularly to electrowetting displays. In related technologies, the pixel electrode of existing electrowetting display devices consists of a common electrode and a positive electrode. The positive electrode is used to apply a driving voltage, and the common electrode is grounded, thereby driving the ink to perform electrowetting display. However, when this pixel electrode drives the ink, problems such as inconsistent ink movement direction and ink breakage are prone to occur, affecting the ink movement speed.

[0035] Based on this, this application proposes a multi-electrode pixel structure, a pixel driving method, a display screen, and a display device. By progressively driving the ink movement of the pixel through multiple sub-electrodes, the ink movement direction is kept consistent, ink breakage is avoided, and the ink movement speed is increased.

[0036] To achieve the above objectives, refer to Figure 1The first aspect of this application proposes a multi-electrode pixel structure, including: a substrate and at least three sub-electrodes, the at least three sub-electrodes being disposed on the substrate, an isolation band being formed between two adjacent sub-electrodes, the isolation band dividing the substrate into at least three regions, the isolation band having the same opening direction; the at least three sub-electrodes driving ink to move along the opening direction of the isolation band according to a progressive driving voltage.

[0037] In electrowetting display technology, when no voltage is applied to the positive electrode of a pixel, the ink naturally spreads within the pixel grid, and the entire pixel displays the same color as the ink (different colored dyes can be added to the ink). When a driving voltage is applied to the positive electrode, causing the ink to gather together, the pixel appears black overall. Related technologies use only one positive electrode to drive the ink movement, resulting in uneven force on the ink droplets within the electrode's coverage area. This leads to inconsistent droplet movement directions and ink breakage, affecting the ink's movement speed and consequently impacting the display's response time. The multi-electrode pixel structure of this application provides multiple sub-electrodes within a pixel region, with different sub-electrodes insulated from each other to form an isolation zone. (Refer to...) Figure 1 The isolation strip has a uniform opening direction. When a time-driven voltage is applied to the sub-electrode, the ink located in that sub-electrode region is forced to move towards the opening direction of the isolation strip, thus accumulating in adjacent sub-electrodes. By applying driving voltages to different sub-electrodes sequentially, the ink is gradually subjected to force, ensuring consistent ink movement direction, preventing ink breakage, and ultimately driving the ink to aggregate together, thereby increasing the speed at which the ink aggregates. For example, as... Figure 1 As shown, a driving voltage is applied to sub-electrode 1 to move the ink in the region of sub-electrode 1 to the region of sub-electrode 2, and then a driving voltage is applied to sub-electrode 2 to move the ink in the region of sub-electrode 2 to the region of sub-electrode 3.

[0038] The multi-electrode pixel structure proposed in this application progressively drives the ink movement of the pixel through multiple sub-electrodes, thereby ensuring that the ink movement direction is consistent, avoiding ink breakage, and improving the ink movement speed.

[0039] In some embodiments, refer to Figure 2 Four sub-electrodes are provided, defined as: first sub-electrode 100, second sub-electrode 200, third sub-electrode 300, and fourth sub-electrode 400. Three isolation bands are provided, defined as: first isolation band 500, second isolation band 600, and third isolation band 700. The combination of the first sub-electrode 100, second sub-electrode 200, third sub-electrode 300, fourth sub-electrode 400, first isolation band 500, second isolation band 600, and third isolation band 700 forms a rectangle. This rectangle represents the pixel grid. Setting the pixel grid as a rectangle reduces the gaps between different pixel grids when applied to a display screen.

[0040] In some embodiments, refer to Figure 2 The first sub-electrode 100 and the fourth sub-electrode 400 are located diagonally opposite each other on the substrate. The fourth sub-electrode 400 is located at one corner of the pixel grid. By applying driving voltages to the first sub-electrode 100, the second sub-electrode 200, and the third sub-electrode 300 respectively, ink is made to accumulate in the area of ​​the fourth sub-electrode 400. When ink needs to be spread, a boosting voltage can be applied to the fourth sub-electrode 400 to make the ink spread quickly in the pixel grid, which is faster than the speed of natural spreading by the ink itself in the prior art.

[0041] In some embodiments, refer to Figure 2 The first isolation band 500, the second isolation band 600, and the third isolation band 700 are all arc-shaped. Preferably, setting the isolation bands to arc shape is more conducive to the uniform movement of ink to adjacent electrodes and avoids ink breakage.

[0042] In some embodiments, refer to Figure 2 The fourth sub-electrode 400 is a fan-shaped electrode, with its arc-shaped edge facing the third sub-electrode 300. By setting the fourth sub-electrode 400 to a fan shape and having its arc-shaped edge facing the third sub-electrode 300, the pushing force generated by the fourth sub-electrode 400 on the ink is applied relatively evenly to the ink droplets during ink spreading, ensuring uniform ink spreading.

[0043] In some embodiments, the widths of the first isolation band 500, the second isolation band 600, and the third isolation band 700 are all less than 10 μm. Smaller isolation band widths are preferable to facilitate ink movement between adjacent electrode regions.

[0044] To achieve the above objectives, refer to Figure 2 and Figure 3 The second aspect of this application proposes a pixel driving method, which is applied to the multi-electrode pixel structure of the first aspect embodiment described above. The multi-electrode pixel structure includes: a first sub-electrode 100, a second sub-electrode 200, and a third sub-electrode 300; the method includes, but is not limited to, steps S100 to S400:

[0045] S100, apply a driving voltage to the first sub-electrode 100, and control the first sub-electrode 100 to continue with the driving voltage for a first preset time;

[0046] S200, apply a driving voltage to the first sub-electrode 100 and the second sub-electrode 200, and control the first sub-electrode 100 and the second sub-electrode 200 to continue with the driving voltage for a second preset duration.

[0047] S300, stop applying the driving voltage to the first sub-electrode 100, apply the driving voltage to the second sub-electrode 200 and the third sub-electrode 300, and control the second sub-electrode 200 and the third sub-electrode 300 to continue with the driving voltage for a third preset duration.

[0048] S400, stop applying driving voltage to the second sub-electrode 200 and the third sub-electrode 300.

[0049] In the embodiments of this application, steps S100 to S400 involve first applying a driving voltage to the first sub-electrode 100, causing the ink in the area of ​​the first sub-electrode 100 to move to the area of ​​the second sub-electrode 200. Then, driving voltages are simultaneously applied to both the first sub-electrode 100 and the second sub-electrode 200, causing the ink in the area of ​​the second sub-electrode 200 to move to the area of ​​the third sub-electrode 300. Applying driving voltages simultaneously to both sub-electrodes 100 and 200 is to prevent some ink droplets from moving towards the area of ​​the first sub-electrode 100 when only the second sub-electrode 200 is driven. Finally, driving voltages are simultaneously applied to both the second sub-electrode 200 and the third sub-electrode 300, causing the ink in the area of ​​the third sub-electrode 300 to move towards the corner of the pixel grid. Figure 2 The ink droplets move in the region of the fourth sub-electrode 400. Similarly, applying driving voltage to both the second sub-electrode 200 and the third sub-electrode 300 simultaneously prevents some ink droplets from moving towards the region of the second sub-electrode 200 when only the third sub-electrode 300 is driven. By applying driving voltage to different sub-electrodes sequentially, the ink is gradually stressed, ensuring consistent ink movement direction, preventing ink breakage, and ultimately causing the ink to aggregate and increasing the speed at which the ink aggregates.

[0050] It should be noted that when the number of sub-electrodes is otherwise specified, the ink movement is controlled by progressively applying driving voltages to different sub-electrodes in a similar manner. This application does not impose specific limitations on the number of sub-electrodes.

[0051] In step S100 of some embodiments, referring to Figure 2 and Figure 4 , Figure 4 The waveform of the driving voltage applied to the first sub-electrode 100 is shown, with the vertical axis representing the driving voltage value and the horizontal axis representing time. Waveform of subslectrode 1 indicates the waveform on the first sub-electrode 100. The first preset duration is 2.5 ms, and the driving voltage is 20V. During the first 2.5 ms, the driving voltage is applied only to the first sub-electrode 100, causing the ink in the area of ​​the first sub-electrode 100 to move to the area of ​​the second sub-electrode 200.

[0052] In step S200 of some embodiments, referring to Figure 2 and Figure 5, Figure 5 The waveforms of the driving voltage applied to the first sub-electrode 100 and the second sub-electrode 200 are shown. The vertical axis represents the voltage value of the driving voltage, and the horizontal axis represents time. Waveformof sub-electrode 1 represents the waveform on the first sub-electrode 100, and Waveform of sub-electrode 2 represents the waveform on the second sub-electrode 200. Figure 5 The driving voltage waveform of the first sub-electrode 100 is represented by a black line, and the driving voltage waveform of the second sub-electrode 200 is represented by a gray line. The second preset duration is 2ms, and the driving voltage is 20V. Starting from 2.5ms, driving voltages are simultaneously applied to the first sub-electrode 100 and the second sub-electrode 200 for 2ms, causing the ink in the area of ​​the second sub-electrode 200 to move to the area of ​​the third sub-electrode 300. Applying driving voltages to both the first sub-electrode 100 and the second sub-electrode 200 simultaneously is to prevent some ink droplets from moving to the area of ​​the first sub-electrode 100 when only the driving voltage is applied to the second sub-electrode 200.

[0053] In step S300 of some embodiments, referring to Figure 2 and Figure 6 , Figure 6 The waveforms of the driving voltages applied to the second sub-electrode 200 and the third sub-electrode 300 are shown. The vertical axis represents the voltage value of the driving voltage, and the horizontal axis represents time. Waveform of sub-electrode 2 represents the waveform on the second sub-electrode 200, and Waveform of sub-electrode 3 represents the waveform on the third sub-electrode 300. Figure 6 The driving voltage waveform of the second sub-electrode 200 is represented by a black line, and the driving waveform of the third sub-electrode 300 is represented by a gray line. The preset duration is 2ms, and the driving voltage is 20V. Starting at 4.5ms, driving voltages are simultaneously applied to both the second sub-electrode 200 and the third sub-electrode 300 for 2ms, causing the ink in the area of ​​the third sub-electrode 300 to move towards the corner of the pixel grid. Similarly, applying driving voltages to both the second sub-electrode 200 and the third sub-electrode 300 simultaneously is to prevent some ink droplets from moving towards the area of ​​the second sub-electrode 200 when only the driving voltage is applied to the third sub-electrode 300.

[0054] In step S400 of some embodiments, after the driving voltage is stopped from being applied to the second sub-electrode 200 and the third sub-electrode 300, the ink will gradually and naturally spread throughout the entire pixel grid.

[0055] Illustrative embodiment, see reference Figure 2 , Figure 4 , Figure 5 and Figure 6The pixel driving method of this application requires 6.5 ms to drive the ink from a state spread throughout the entire pixel grid to a state gathered in one corner of the pixel grid. In the prior art, it takes 10 ms to drive ink gathering with a single pixel electrode. Therefore, the pixel driving method of this application effectively improves the ink movement speed and greatly reduces the time required for ink gathering.

[0056] In some embodiments, refer to Figure 2 and Figure 7 The multi-electrode pixel structure also includes: a fourth sub-electrode 400, and the method further includes, but is not limited to, steps S500 and S600:

[0057] S500, apply a boosting voltage to the fourth sub-electrode 400, and control the fourth sub-electrode 400 to maintain the boosting voltage for a fourth preset duration.

[0058] S600, stop applying boost voltage to the fourth sub-electrode 400.

[0059] Steps S500 and S600 shown in this embodiment of the application, compared with the natural spreading of ink in the prior art, accelerate the ink spreading speed by applying a boosting voltage to the fourth sub-electrode 400 and maintaining it for a certain period of time.

[0060] In step S500 of some embodiments, refer to Figure 2 and Figure 8 , Figure 8 The waveform of the boost voltage applied to the fourth sub-electrode 400 is shown. The vertical axis represents the driving voltage value, and the horizontal axis represents time. Waveform of sub-electrode 4 indicates the waveform on the fourth sub-electrode 400. The boost voltage is 15V, and the preset duration is 1ms. Applying a boost voltage to the fourth sub-electrode 400 accelerates the ink spreading speed.

[0061] In step S600 of some embodiments, after the ink has spread into the pixel grid, the boost voltage applied to the fourth sub-electrode 400 is stopped.

[0062] Illustrative embodiment, see reference Figure 9 and Figure 10 . Figure 9 This paper presents a comparison diagram of the pixel-driving method of this application and the prior art driving ink aggregation, showing the effect of pixel-driving method. Figure 9 As can be seen, compared with the single-electrode driving of the prior art, the multi-electrode progressive driving of this application has a faster ink aggregation speed and a better aggregation effect. Figure 10The diagram shows a comparison of the effects of the pixel driving method of this application and the prior art in driving ink spreading. Compared with the prior art, which allows ink to spread naturally, this application applies a boosting voltage to the electrodes of the ink gathering area to make the ink spread more quickly in the pixel grid.
