Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Aiming at the problems in the prior art, some schemes are that the light intensity is sensed by a photoelectric sensor and the curtain automatically hangs down by a control circuit, but the mechanical operation is slow, so that the curtain is not suitable for scenes with instant strong light. Some schemes prevent transient blinding caused by instantaneous strong light through a car window adhesive film or polarized glass, but the schemes can prevent light from entering the car and still cause potential safety hazards when the car runs under dark and weak light such as night or tunnels.
In addition, in the scheme of forming the light shielding structure by using the electronic ink, the light transmittance of the electronic ink is low, so that potential safety hazards are still easily caused during night driving.
To this end, the present disclosure provides a light control glass for a vehicle window, as shown in fig. 1, including a first transparent substrate 10, a first transparent electrode layer 20, a second transparent substrate 30 and a second transparent electrode layer 40, where the first transparent substrate 10 and the second transparent substrate 30 are disposed opposite to each other, a plurality of micro channels are disposed between the first transparent substrate 10 and the second transparent substrate 30, an electrowetting material is disposed in the micro channels, the first transparent electrode layer 20 is disposed on a side of the first transparent substrate 10 away from the second transparent substrate 30, the second transparent electrode layer 40 is disposed on a side of the second transparent substrate 30 away from the first transparent substrate 10, the first transparent electrode layer 20 and the second transparent electrode layer 40 are disposed to apply a voltage to the electrowetting material disposed between the first transparent substrate 10 and the second transparent substrate 30, so that the electrowetting material is spread over the micro channels, and applying a voltage to the electrowetting material that fills the microchannel, changing a light transmittance of the electrowetting material, the electrowetting material located between the first transparent substrate and the second transparent substrate being arranged to fill the microchannel and change the light transmittance when the voltage is applied.
Electrowetting (EW) refers to a phenomenon in which a droplet is deformed or displaced by changing the wettability of the droplet on an underlying substrate, that is, by changing a contact angle, by changing a voltage between substrates located on both sides. Wetting is one of the main properties of a solid surface on which a liquid can spread and the solid-liquid contact surface has a tendency to expand, i.e. the liquid has a greater adhesion to the solid surface than its cohesion, and such a surface is considered to be inherently inclined to be hydrophilic, i.e. wetting. Conversely, a liquid does not spread on a solid surface, and the interface of the liquid with the solid surface has a tendency to shrink into a spherical shape, and such a surface is considered to be inherently hydrophobic, i.e., non-wetting, i.e., the liquid adheres less strongly to the solid surface than it coheres to it. The wettability of solid surfaces is typically determined by Contact Angle (CA) measurements. Fig. 2 is a schematic diagram of the contact angle of a droplet. As shown in fig. 2, for a liquid on a horizontal surface, the contact angle θ is believed to be a result of three different types of surface tensions at the solid/liquid/gas interface. Lyophilic means that the contact angle of a liquid drop on a solid surface is less than 90 degrees, and lyophobic means that the contact angle of the liquid drop on the solid surface is more than 90 degrees.
The wetting effect of the solid surface can be changed using a voltage such that the solid surface becomes more hydrophilic, i.e. the wettability of the solid surface is enhanced. Fig. 3a and 3b are schematic diagrams of driving droplet movement according to an embodiment of the present invention. As shown in FIG. 3a, for any micro flow channel, at least 3 pressurizing regions can be included, each pressurizing region is pressurized by an electrode, and the voltage corresponding to the first region in the 3 pressurizing regions is assumed<Voltage corresponding to the second region<The third region corresponds to a voltage, and the droplet 100 will exhibit a different degree of wetting, i.e., a different solid-liquid contact angle. Wherein the lyophilic strength of the first region<Lyophilic strength of the second region<Lyophilic strength of the third area, i.e. lyophobic strength of the first area>Liquid repellency strength of the second region>The lyophobic strength of the third area, the contact angle theta of the first area1>Contact angle theta of the second region2>Contact angle theta of the third region3. Based on liquidThe physical properties of the droplets are such that the droplets move from a region with a large lyophobic strength to a region with a small lyophobic strength by the internal pressure difference, that is, the droplets in a low wetting region move to a more wetting region by the internal pressure difference. Therefore, when the liquid drop 100 is located in the first area, the surface tension is asymmetrically distributed due to different portions of the same liquid drop having different solid-liquid contact angles, a pressure difference exists inside the liquid drop, so that the liquid drop 100 is driven to move towards the second area by the internal pressure difference, and when the liquid drop 100 is located in the second area, the liquid drop 100 is driven to move towards the third area. By controlling the voltage difference between two adjacent areas, the change gradient of the contact angle of the liquid in the two adjacent areas can be controlled, namely the moving speed of the liquid drop can be controlled. By controlling the voltage difference between two adjacent regions in a certain direction, the gradient of the contact angle between two adjacent regions in the corresponding direction can be controlled, i.e. the moving direction of the liquid drop can be controlled, as shown in fig. 3 b.
Therefore, when a voltage is applied to the electrowetting material in the micro channel through the transparent electrode 20, the wettability of the contact surface of the micro channel and the electrowetting material is enhanced, so that the contact angle between the edge of the electrowetting material and the surface of the micro channel is changed, the liquid drop at the edge of the electrowetting material is deformed, the liquid drop at the edge of the electrowetting material is driven to continuously move along the micro channel, and the electrowetting material is further paved on the micro channel.
After the electrowetting material is paved on the micro channel, voltage can be applied to the electrowetting material through the electrodes positioned on two sides of the micro channel, and the display gray scale of the electrowetting material is changed. Take the electrowetting material as an electronic ink as an example. The electronic ink comprises a plurality of microcapsules, each microcapsule comprising dye particles, in particular negatively charged black dye particles and positively charged white dye particles. Under the action of voltages with different sizes, the shading dye particles are dispersed in different positions in the microcapsule, so that the light transmittance of the microcapsule is different, and the gray scales of the electronic ink are different.
One way is to apply three different voltages simultaneously to the microcapsules, the voltages comprising: a reference voltage and two adjustable voltages, a first adjustable voltage V1 and a second adjustable voltage V2; gray scale display is realized by adjusting the voltage of V1 and V2, thereby adjusting the distribution of the charged dye particles on the substrate.
As shown in fig. 4 (the substrate is not shown), in the present exemplary embodiment, the first transparent electrode layer may include a plurality of first electrodes 201 and second electrodes 202 arranged at intervals, the second transparent electrode layer is arranged as a third electrode 40, the third electrode 40 is used for applying a reference voltage, the first electrodes 201 are used for applying a first adjustable voltage, and the second electrodes 202 are used for applying a second adjustable voltage.
The gray scale display is realized by setting the first adjustable voltage to be less than or equal to the reference voltage and setting the second adjustable voltage to be greater than or equal to the reference voltage. Taking 16-level gray scale display as an example, when the voltages of the first electrode 201 and the third electrode 40 are the same and there is no voltage difference, the voltage difference between the second electrode 202 and the third electrode 40 is the maximum (the maximum voltage difference is denoted by Vd), the gray scale display is 0 level; when the voltage difference between the first electrode 201 and the third electrode 40 is Vd/4, and the voltage difference between the second electrode 202 and the third electrode 40 is 3Vd/4, the display gray scale is 4 levels; when the voltage difference between the first electrode 201 and the third electrode 40 is Vd/2, and the voltage difference between the second electrode 202 and the third electrode 40 is Vd/2, the display gray scale is 8 levels; when the voltage difference between the first electrode 201 and the third electrode 40 is 3Vd/4, and the voltage difference between the second electrode 202 and the third electrode 40 is Vd/4, the display gray scale is 12 levels; when the voltage difference between the first electrode 201 and the third electrode 40 is Vd, the voltage on the second electrode 202 is the same as the voltage on the third electrode 40, and the display gray scale is 16 levels without the voltage difference. The higher the grey scale, the more black dye particles are located in the upper layer.
The glass substrate-based microfluidic chip is a mature and complete manufacturing process. In the embodiment of the disclosure, the micro channel groove may be formed on the first transparent substrate and/or the second transparent substrate by a patterning process, then the substrate is subjected to a surface active treatment to form a hydrophobic surface, the first transparent substrate and the second transparent substrate are annealed and bonded to form the micro channel, and then the first transparent electrode layer and the second transparent electrode layer are formed on the first transparent substrate and the second transparent substrate. The electronic ink can be injected into the micro-channel by magnetron sputtering or evaporation process.
In an exemplary embodiment, a light adjusting device may include the above light adjusting glass and a controller configured to be connected to the first transparent electrode layer and the second transparent electrode layer, respectively, for controlling a voltage between the first transparent electrode layer and the second transparent electrode layer. Specifically, the controller is connected to the first electrode and the second electrode of the first transparent electrode layer, and to the third electrode of the second transparent electrode layer, respectively.
The embodiment of the present disclosure further provides a dimming panel, as shown in fig. 5, including a sensor 1, a controller 2, and the aforementioned dimming glass 3, wherein:
the sensor 1 is arranged to detect light intensity;
the controller 2 is arranged to send a voltage signal to the light control glass according to the light intensity detected by the sensor;
the dimming glass 3 comprises a first transparent electrode layer, a first transparent substrate, a second transparent electrode layer and a second transparent substrate, wherein the first transparent substrate and the second transparent substrate are arranged oppositely, a plurality of micro channels are arranged between the first transparent substrate and the second transparent substrate, electrowetting materials are arranged in the micro channels, the first transparent electrode layer is positioned on one side, away from the second transparent substrate, of the first transparent substrate, the second transparent electrode layer is positioned on one side, away from the first transparent substrate, of the second transparent substrate, the first transparent electrode layer and the second transparent electrode layer are arranged to apply voltage to the electrowetting materials between the first transparent substrate and the second transparent substrate according to voltage signals sent by the controller, so that the electrowetting materials are fully paved in the micro channels, and voltage is applied to the electrowetting materials fully paved in the micro channels, changing a light transmittance of the electrowetting material, the electrowetting material located between the first transparent substrate and the second transparent substrate being arranged to fill the microchannel when a voltage is applied, and changing the light transmittance.
In an exemplary embodiment, the sensor may be a photodetector. When the strong light beam irradiates the photoelectric detector, the photoelectric detector can convert the light signal into an electric signal, the photoelectric detector outputs different currents according to the received light intensity, and the controller can judge the light intensity according to the current signal. The photoelectric detector has the advantage of quick response, and the detection time can be within 30 ms.
In an exemplary embodiment, as shown in fig. 6, the controller includes an optical signal receiving unit 21 for receiving an optical intensity signal, a converting unit 22 for determining a voltage value from the optical intensity signal, and a voltage generating circuit 23 for generating a voltage from the calculated voltage value. The conversion unit can select a voltage value which enables the dimming glass to generate corresponding gray scale according to the current light intensity in a table look-up mode. The voltage generation circuit can be implemented by a circuit in the prior art, and is not described in detail herein.
The light control glass can be used as a front windshield of a vehicle, as shown in fig. 7. One or more sensors may be provided. When a plurality of sensors are arranged, the controller can judge that when the light intensity is larger than a preset threshold value according to the average light intensity of the sensors, the electrowetting materials are controlled to be fully paved on the micro flow channel, and the strong light is shielded by changing the transmittance.
In an exemplary embodiment, the light sensor may also be used to activate or deactivate a dimming function of the dimming panel. For example, when the light intensity signal sent by the sensor is lower than a first threshold value, which indicates that the dimming glass is at night currently, the controller starts the dimming function of the dimming glass. Alternatively, one of the plurality of sensors may be configured to detect ambient light, and when the controller determines that the light intensity signal sent by the sensor is lower than the first threshold, the remaining sensors are activated to activate the dimming function. For another example, when the sensor sends a light intensity signal that is too high, e.g., greater than a second threshold, indicating that the daylight illumination is currently intense, then the controller may also activate the remaining sensors.
Starting behind the dimming function, work as when the luminous intensity that detects of sensor is greater than the second threshold value, the controller sends first group voltage signal to dimming glass, makes the electrowetting material pave the microchannel, and to dimming glass sends second group voltage signal, reduces the luminousness of electrowetting material, avoids the driver directly to receive the intense light and shines, prevents that the highlight from leading to driver's vision blind spot, improves the security of driving night. The voltage signal group comprises a voltage signal sent to the first transparent electrode and a voltage signal sent to the second transparent electrode, and the specific voltage value can be determined according to a simulation result, for example, under which light intensity is determined in simulation, which light transmittance is most suitable is adopted, and a corresponding voltage value is recorded. When the detected light intensity is in the range needing dimming, the corresponding voltage value is selected, the voltage generating circuit generates corresponding voltage, and the electrodes in the first transparent electrode layer and the second transparent electrode layer apply corresponding voltage to the electrowetting material.
In an exemplary embodiment, the controller may send a voltage signal to the light control glass according to the intensity of light detected by the sensor in the following manner:
the optical signal receiving unit is used for judging whether the detected light intensity of the sensor is greater than a second threshold value or not;
the conversion unit is used for determining a first group of voltage signals for enabling the electrowetting material to be paved in a micro channel and a second group of voltage signals for changing the light transmittance of the electrowetting material when the optical signal receiving unit judges that the detected light intensity of the sensor is greater than a second threshold value;
the voltage generation circuit is used for generating a first group of voltage signals and a second group of voltage signals in a time-sharing mode.
In an exemplary embodiment, when the light intensity is less than the third threshold, the controller may send a third voltage signal to the light control glass to move the electrowetting material away from a microchannel in the driver's sight, or send a fourth voltage signal to the light control glass to increase the light transmittance of the electrowetting material. When the light transmittance of the electrowetting material is increased, a table can be looked up to obtain a voltage value. For example, at the first moment, the light intensity is strong, the gray scale value corresponding to the light control glass is 8 levels, the corresponding first electrode voltage value, second electrode voltage value and third electrode voltage value can be obtained by looking up a table, and the voltage is applied to the electrowetting material in the micro channel through the first transparent electrode layer and the second transparent electrode layer, so that the gray scale value of the light control glass is 8 levels. And at the second moment, the light intensity is weakened, the gray-scale value corresponding to the dimming glass is 4 levels, the corresponding first electrode voltage value, the second electrode voltage value and the third electrode voltage value can be obtained by looking up a table, and the voltage is applied to the electrowetting material in the micro channel through the first transparent electrode layer and the second transparent electrode layer, so that the gray-scale value of the dimming glass is 4 levels.
In an exemplary embodiment, the micro flow channel may be located locally on the front windshield, for example, in the area of the driver's sight line location. Or may be located across the front windshield.
