Technical Field

[0001] The present invention relates to the field of electrowetting driving technology, and in particular to a high-brightness electrowetting driving method, device and storage medium thereof. Background Art

[0002] Reflective displays do not require a backlight source and can be displayed by ambient light. They are more suitable for outdoor use and are widely used. The electrowetting driver is a type of reflective display. It is a technology that can change the contact angle between the droplet and the hydrophobic insulating layer when a voltage is applied. It has the advantages of being readable in the sun, a wide viewing angle, and low power consumption. Electrowetting is mainly composed of a substrate, indium tin oxide, a hydrophobic insulating layer, a pixel wall, ink, and a conductive liquid. When the driving voltage is not applied, the ink is spread between the hydrophobic insulating layer and the conductive liquid. At this time, the substrate presents the color of the ink, and the pixel is in the off state. When the driving voltage is applied, the ink shrinks and detaches from the surface of the oleophilic and hydrophobic insulating layer. Most of the reflected light can be reflected directly after passing through the conductive liquid, and only a small part passes through the ink and cannot be reflected, thereby presenting the color of the substrate, and the pixel is in the on state. In the prior art, due to the presence of charge in the hydrophobic insulating layer, the electrowetting ability of the ink will decrease when a voltage is applied, and the ink will show ink reflux on the hydrophobic insulating layer, affecting the display effect of the electrowetting driver. In addition, in order to improve the brightness of the electrowetting driver, the driving voltage needs to be increased, but an excessively large driving voltage will damage the hydrophobic insulating layer and affect the service life of the electrowetting driver.

[0014] The high-brightness electrowetting driving method, device and storage medium involved in the embodiment of the present invention provide a DC driving signal to the conductive liquid at a first voltage value to eliminate or capture the charge in the hydrophobic insulating layer, the first voltage value is less than the display voltage; provide a driving signal to the conductive liquid at a second voltage value, the second voltage value gradually increases along the rising function; provide an AC driving signal to the conductive liquid with a third voltage value as the amplitude to reduce the reflux of the ink, wherein the third voltage value is determined by the peak value of the second voltage value. Adjust the driving voltage at different stages to effectively eliminate or capture the charge in the hydrophobic insulating layer, inhibit ink splitting, improve the electrowetting brightness, shorten the electrowetting response time, and reduce the flickering phenomenon of the high-brightness electrowetting display system.

[0015] Electrowetting (Electrowetting, EW) refers to the phenomenon of changing the wettability of a droplet on its underlying solid structure (generally a strongly hydrophobic material) by applying a voltage between the upper and lower substrates, that is, changing the contact angle, causing the droplet to deform and displace. Among them, wetting refers to the process in which one fluid on the solid surface is replaced by another fluid. The liquid can spread on the solid surface, and the solid-liquid contact surface tends to expand, that is, the adhesion of the liquid to the solid surface is greater than its cohesion. The liquid cannot spread on the solid surface, and the contact surface tends to shrink into a sphere, which is non-wetting. Non-wetting means that the adhesion of the liquid to the solid surface is less than its cohesion. Specifically, the electrowetting display system is mainly composed of a substrate, indium tin oxide, a hydrophobic insulating layer, a pixel wall, ink, and a conductive liquid. When no driving voltage is applied, the ink is spread between the hydrophobic insulating layer and the conductive liquid, and the substrate presents the color of the ink. At this time, the corresponding pixel point is in a closed state. When the driving voltage is applied, the ink shrinks and detaches from the surface of the oleophilic and hydrophobic insulating layer. Most of the reflected light can be reflected directly after passing through the conductive liquid, and only a small part passes through the ink and cannot be reflected, thereby presenting the color of the substrate. At this time, the corresponding pixel point is in the on state. Due to the presence of electric charge in the hydrophobic insulating layer, the electrowetting ability of the ink will decrease when voltage is applied. The ink will show ink reflux on the hydrophobic insulating layer, affecting the display effect of the electrowetting driver. In addition, in order to increase the brightness of the electrowetting driver, it is necessary to increase the driving voltage, and excessive driving voltage will damage the hydrophobic insulating layer and affect the service life of the electrowetting driver. At present, the existing electrowetting display system has problems such as insufficient brightness and poor display effect, which affects the promotion and application of the electrowetting display system.

[0016] Based on the above, the embodiments of the present invention provide a high-brightness electrowetting driving method, device and storage medium thereof, which provide a DC driving signal to the conductive liquid at a first voltage value to eliminate or capture the charge in the hydrophobic insulating layer, wherein the first voltage value is less than the display voltage; provide a driving signal to the conductive liquid at a second voltage value, wherein the second voltage value gradually increases along the rising function; provide an AC driving signal to the conductive liquid at a third voltage value as the amplitude to reduce the reflux of the ink, wherein the third voltage value is determined by the peak value of the second voltage value. The driving voltage is adjusted at different stages to effectively eliminate or capture the charge in the hydrophobic insulating layer, inhibit ink splitting, improve the electrowetting brightness, shorten the electrowetting response time, and reduce the flickering phenomenon of the high-brightness electrowetting display system.

[0017] See also Figure 1 , Figure 1 FIG. 2 shows the process of the high brightness electrowetting driving method provided by an embodiment of the present invention. Figure 1 As shown, the high brightness electrowetting driving method of the embodiment of the present invention comprises the following steps: Step S1000: Using a first voltage value A DC driving signal is provided to the conductive liquid to eliminate or capture the charge in the hydrophobic insulating layer. The first voltage value Less than the displayed voltage.

[0018] It is understandable that if Figure 2 As shown, Figure 2 The driving waveform of the embodiment of the present application is divided into three stages, namely, the charge control stage, the ink splitting suppression stage and the ink stabilization stage. The first stage is the charge control stage. Specifically, a DC driving signal is provided to eliminate or capture the charge in the hydrophobic insulating layer, improve the brightness of the electrowetting, and shorten the response time of the electrowetting.

[0019] It is understandable that the first voltage value is less than the display voltage, that is, the driving voltage amplitude provided in the first stage is lower than the turn-on voltage of the electrowetting display pixel. In the first stage, the electrowetting pixel is in the off state and the first voltage value is applied. , which helps to release or reduce the charge in the hydrophobic insulating layer and shorten the response time of electrowetting. There are some conductive particles in the conductive liquid. When a driving voltage is applied to electrowetting, the conductive particles in the conductive liquid are pulled toward the hydrophobic insulating layer by the electrostatic force. When the interaction between the conductive ions and the hydrophobic insulating layer is stronger than the interaction between the conductive ions and the conductive liquid, there will be trapped charges in the hydrophobic insulating layer.

[0020] Specifically, in the charge control stage, a DC driving voltage is applied to eliminate or capture the charge captured in the hydrophobic insulating layer, thereby improving the response speed and aperture ratio of the ink. The aperture ratio of the ink refers to the ratio of the surface area not covered by the ink to the total pixel area. The calculation formula is as follows:

[0021] in, is the surface area not covered by ink, is the total area of ​​the pixel.

[0022] In some embodiments, the first voltage value Between -9~5V, the first voltage value The first driving time of providing a DC driving signal to the conductive liquid Between 1 and 30 ms. Figure 3 , Figure 3 The structure diagram of the brightness test device under different driving voltages and driving times in the embodiment of the present application is shown. Specifically, the driving waveform is first designed in the computer 100 and imported into the arbitrary waveform function generator 500, the generated driving signal is amplified 10 times by the voltage amplifier 400, the voltage amplifier 400 is connected to the electrowetting display 300, and the driving signal output by the driving waveform is output to the electrowetting display 300, and the colorimeter 200 is connected to the computer 100 to measure the brightness value of the electrowetting display 300 through the colorimeter 200.

[0023] In the specific test process, first, the voltage and time of the driving waveform are edited in the computer 100 and saved as a driving waveform file. Then, the driving waveform file is stored in a USB flash drive using the waveform editing software. Then, the driving waveform is imported into the arbitrary waveform function generator 500 using the universal serial bus interface, and the corresponding driving waveform is selected on the arbitrary waveform function generator 500, and the voltage and time of the driving waveform are adjusted. Among them, the output end of the arbitrary waveform function generator 500 is connected to the input end of the voltage amplifier 400, and the positive and negative poles of the voltage amplifier 400 are respectively connected to the positive and negative ends of the electrowetting display 300, and the magnification is adjusted. In the above-mentioned test process, the input resistance of the voltage amplifier 400 is adjusted to 100, and the voltage magnification of the voltage amplifier 400 is 10 times. Then, the colorimeter 200 is connected to the computer 100, and the colorimetry software is opened in the computer 100, and the colorimeter 200 is calibrated, so that the electrowetting brightness data can be correctly collected. Then, the colorimeter 200 is placed on the electrowetting 100, and the output terminals of the arbitrary waveform function generator 500 and the voltage amplifier 400 are turned on to start testing the brightness data of the electrowetting display 300. Finally, the brightness data measured by the colorimeter 300 is saved on the colorimetric measurement software, and the brightness curve data is obtained and output as follows: Figure 4 The test results are shown.

[0024] like Figure 4 As shown, in this embodiment, by measuring the first stage at different first voltage values , Different first drive time The brightness under the condition of vs. brightness, where The test range is from 10ms to 25ms, the first voltage value The test range is from -9V to 5V. Figure 4 From the curve diagram, we can see that when When the value is 10ms, the brightness is significantly higher than the brightness under other first driving times; When the value is -9V, the brightness is at the highest point. Therefore, the optimal first driving time is obtained. The optimal first voltage value is -9V.

[0025] Step S2000: providing a driving signal to the conductive liquid with a second voltage value, wherein the second voltage value gradually increases along an ascending function.

[0026] It is understandable that if Figure 2As shown, the second stage of the driving waveform of the embodiment of the present application is the stage of suppressing ink splitting. Specifically, ink splitting refers to the phenomenon that the oil film splits into several small oil films during the contraction process and cannot be reorganized. The ink contraction process can be divided into the ink rupture process and the ink wetting process. The ink rupture process refers to the ink splitting when the driving voltage reaches the voltage threshold of ink splitting. The wetting process is the process in which the ink shrinks to the corner of the pixel and the final contact angle reaches the Lippmann equilibrium contact angle. Therefore, it is necessary to control the second voltage value Steadily rising, ensuring Under the premise of being less than the voltage threshold of ink splitting, the brightness of the electrowetting display can be effectively improved to avoid the occurrence of ink splitting.

[0027] It is understandable that the second voltage value The value gradually increases along the rising function, and the rising function includes but is not limited to exponential function, power function, sine function and cosine function. Figure 2 As shown, the second voltage value During the second drive The rising curve in the circuit is a part of the exponential function, power function, sine function and cosine function, which can effectively ensure the second voltage value. The second voltage value increases steadily, improving the brightness of the electrowetting display. During the second drive The upward trend can effectively reduce the response time of electrowetting.

[0028] In some embodiments, the second voltage value The duration of providing the driving signal to the conductive fluid Between 20 and 200 ms. As in step S1000 above, by measuring the second stage at different second voltage values , different second drive time The brightness under the second driving time is obtained The value range of is 20~200ms. The specific value can be determined according to the specific parameters of the electrowetting display, which will not be described here.

[0029] Step S3000: providing an AC driving signal to the conductive liquid with a third voltage value as an amplitude to reduce the backflow of the color ink, wherein the third voltage value is determined by the peak value of the second voltage value.

[0030] It is understandable that if Figure 2As shown, the third stage of the driving waveform of the embodiment of the present application is the stable ink stage. Specifically, there are some conductive particles in the conductive liquid. When the driving voltage is applied to the electrowetting display, the conductive particles in the conductive liquid will be pulled toward the hydrophobic insulating layer by the electrostatic force. When the interaction between the conductive ions and the hydrophobic insulating layer is stronger than the interaction between the conductive ions and the conductive liquid, there will be trapped charges in the hydrophobic insulating layer. Ink reflux is one of the main defects in electrowetting pixels, which will cause the brightness of electrowetting to gradually decrease. Specifically, under the action of the driving voltage, part of the charge is captured in the hydrophobic insulating layer, and a local reverse electric field is formed at the interface between the hydrophobic insulating layer and the conductive liquid in the electrowetting pixel, and the reverse electric field will weaken the driving electric field at the three-phase contact line. At the same time, the reverse electric field can continuously enhance the electric field strength through the charge, and weaken the electric field strength of the applied driving voltage as time increases. Therefore, when the driving voltage is applied, the charge capture will cause the electrowetting ability of the ink to decrease, and the hydrophobicity of the hydrophobic insulating layer will gradually increase. At this time, the three-phase contact line cannot be kept in a fixed position, and the ink will show ink reflux on the hydrophobic insulating layer. Therefore, it is necessary to provide an AC driving signal to the conductive liquid with a third voltage value as the amplitude to reduce the reflux of the color ink.

[0031] In some embodiments, the third voltage value The second voltage value The peak value is determined by the above step S2000. The third voltage value increases gradually along the rising function. Specifically, when the rising function is an exponential function, the third voltage value and the second voltage value The starting voltage satisfies the following formula:

[0032] in, The second voltage value The starting voltage, is the preset time coefficient, specifically, .

[0033] In some embodiments, the frequency of the AC driving signal is between 50 and 300 Hz. The AC square wave voltage amplitude follows the DC balance principle and is optimized according to the AC square wave frequency at this stage. DC balance is a state in which the number of 1s and 0s in a data stream is equal, or a technology that makes the number of 1s and 0s in a data stream equal. In the case of DC balance, the average power consumption of the transmission is a constant. Therefore, Figure 2 As shown, in the ink stabilization stage, the third voltage value As the amplitude, an AC driving signal is provided to the conductive liquid, that is, , and the reverse voltage driving time Drive time vs. forward voltage The same size makes the AC square wave voltage amplitude follow the principle of DC balance.
