This application claims priority to Chinese Patent Application No. 202011194006.9 filed on Oct. 30, 2020, which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of display technology, in particular to a windowing device and a windowing system.
Along with the development of the intelligent display technology, smart dimming glass is provided with different light transmittance depending on different voltages, temperatures and light intensities, so it has widely applied in different fields, e.g., electronic screen, vehicle window, traffic lamp and architectural glass.
As compared with electrochromic dimming glass, dye-doped liquid crystal dimming glass has a wider application prospect due to such advantages as rapid response and high contrast. However, in different application fields and regions, mobility of dye-doped liquid crystals in the dye-doped liquid crystal dimming glass is greatly different due to influences caused by a difference in a climate change in different seasons and a difference in a temperature in different regions.
On one hand, at a high temperature, the dye-doped liquid crystals have a small viscosity coefficient, so they are capable of being rapidly arranged in a twisted manner in an electric field direction under the effect of an electric field. On the other hand, at a low temperature, the dye-doped liquid crystals have a large viscosity coefficient, so it is necessary to apply the electric field thereto within a long time period so as to acquire a desired twisting angle. Based on this, due to the doping with dye, ionization may occur inside the liquid crystal to generate a built-in electric field when an external electric field is applied to the dye-doped liquid crystal at the high temperature. Further, at the low temperature, an adjustment voltage at a normal temperature is applied, and due to different states of the liquid crystals in different regions, an uneven light transmittance may occur within a long time period after the liquid crystals are energized. In addition, in the case of market use, a same operating voltage and an uneven light transmittance of the dimming glass may occur due to a difference in the temperature in different regions, e.g., with or without sunlight.
Based on the above, when the dye-doped liquid crystal dimming glass is adopted, it is necessary to prevent the occurrence of dimming abnormalities in different operating environments.

In some possible embodiments of the present disclosure, the dimming transparent substrate 110 may be light-transmitting transparent substrate, which includes dye-doped dimming liquid crystals formed through doping liquid crystals in a nematic phase with dye. When no electric field is applied, liquid crystal molecules between two parallel substrates in the light-transmitting transparent substrate may be in a multi-domain arrangement state in a direction parallel to the substrate under the effect of an alignment layer. In addition, when the electric field has been applied, the liquid crystal molecules may be deflected gradually under the effect of the electric field, and converted from the multi-domain arrangement parallel in the direction parallel to the substrate to a single-domain arrangement state in a direction perpendicular to the substrate. At this time, visible light may be transmitted, rather than scattered, in the liquid crystal layer, and an OFF state may be converted into an ON state, so as to switch between a bright state and a dark state. Further, the light transmittance of the liquid crystal layer may be affected jointly by a mass percentage of the dye doped in the liquid crystal layer as well as a driving voltage, so as to adjust the light transmittance of incident light.
In some possible embodiments of the present disclosure, the semiconductor temperature adjustment element 120 may adjust the temperature on the basis of a Peltier principle. The semiconductor temperature adjustment element 120 may include a plurality of Peltier structures, and a direction-variable constant current source may be applied through the Peltier structures, so as to adjust the temperature of the dimming transparent substrate.

The controller 300 may determine a current temperature state of the windowing module 100 in accordance with the temperature collected by the temperature sensor 10, and when the temperature of the windowing module 100 is beyond the predetermined temperature range, the temperature adjustment circuitry 200 may adjust the current inputted to the Peltier structure 121.
In some possible embodiments of the present disclosure, when the temperature detected by the temperature sensor 10 is greater than the upper threshold of the predetermined temperature range, i.e., the environment temperature is too high, the temperature adjustment circuitry 200 may input the current in the first direction to the Peltier structure 121, so as to enable a surface of the Peltier structure 121 adjacent to the liquid crystal layer to be a cooling surface, thereby to cool the windowing module 100. When the temperature detected by the temperature sensor 10 is smaller than or equal to the lower threshold of the predetermined temperature range, i.e., the environment temperature is relatively low, the temperature adjustment circuitry 200 may input the current in the second direction to the Peltier structure 121, so as to enable the surface of the Peltier structure 121 adjacent to the liquid crystal layer to be a heating surface, thereby to heat the windowing module 100.
Hence, based on the above, it is able to ensure the temperature of the windowing module 100 within the predetermined temperature range, thereby to prevent the occurrence of the dimming abnormalities for the dimming glass due to different light transmittances in different operating environments.
In the embodiments of the present disclosure, the dimming driving module 500 is configured to input an adjustment parameter to the dimming transparent substrate 110, so as to provide the dimming transparent substrate with different light transmittances when different adjustment parameters are inputted.

In some possible embodiments of the present disclosure, as shown in
In some possible embodiments of the present disclosure, the first pole 1211, the second pole 1212 and the thermally-conductive line 1213 may be each made of a transparent material.

Identical to that in
In the Peltier structure 121 as shown in
The first pole and the second pole of each Peltier structure 121 at two sides of the liquid crystal layer 122 have opposite polarities, so when a current in a same direction is applied to the first pole and the second at the two opposite sides and the electrode surface of the first pole adjacent to the liquid crystal layer 122 is a heating surface, the polarity of the second pole at the other side may be opposite to the polarity of the first pole, and the electrode surface of the second pole adjacent to the liquid crystal layer 122 may also be a heating surface. Identically, when the electrode surface of the first pole adjacent to the liquid crystal layer 122 is a cooing surface, the electrode surface of the second electrode adjacent to the liquid crystal layer 122 may also be a cooling surface.
Based on the above, when the temperature of the dimming transparent substrate 110 has been detected, the temperature adjustment circuitry 200 may input different currents to the Peltier structures 121. When the detected temperature is smaller than or equal to the lower threshold of the predetermined temperature range, the temperature adjustment circuitry 200 may input the current in the second direction, so as to enable the electrode surface of each Peltier structure 121 adjacent to the liquid crystal layer 122 to be the heating surface, thereby to heat the windowing module 100. When the detected temperature is greater than the upper threshold of the predetermined temperature range, the temperature adjustment circuitry 200 may input the current in the first direction, so as to enable the electrode surface of each Peltier structure 121 adjacent to the liquid crystal layer 122 to be the cooling surface, thereby to cool the windowing module 100.
In some possible embodiments of the present disclosure, the current in the second direction may be a forward current, and the current in the first direction may be a backward current.

As compared with a situation where a size of the transparent display panel 130 is arranged in accordance with a size of the dimming transparent substrate 110, the transparent display panel 130 may be arranged on a part of the dimming transparent substrate 110 to provide a regional display effect, so as to meet the requirement in a scenario where an interaction function is merely provided on a regional basis, thereby to prevent the occurrence of such problems as high cost and high power consumption when a display screen is provided on the entire dimming transparent substrate.
In some possible embodiments of the present disclosure, as shown in

In some possible embodiments of the present disclosure, the windowing system may be applied to a smart vehicle window IoT system, and the windowing device may be a window of the train or subway. As shown in
The communication module, the computation gateway and the windowing devices may be combined together to form IoT architecture.

In some possible embodiments of the present disclosure, as shown in
In some possible embodiments of the present disclosure, the signal conversion unit may include an operational amplification (OA) sub-unit, a signal amplification (SA) sub-unit, an analog-to-digital conversion (ADC) sub-unit and a signal output sub-unit.
In some possible embodiments of the present disclosure, the fault detection module may further include: a data storage unit coupled to the diagnosis analysis unit and configured to store the detection result of the diagnosis analysis unit; and a fault communication unit coupled to the diagnosis analysis unit and configured to transmit the detection result of the diagnosis analysis unit to a transmission network of the vehicle window IoT system.
Through the fault detection module with the above-mentioned structure, it is able to acquire a power supply situation through detecting voltages and currents applied to the control panels, thereby to determine whether each board card operates normally.
In some possible embodiments of the present disclosure, the windowing system may further include an image collection module configured to collect a display state of the windowing module. The display state collected by the image collection module may be transmitted to the transmission network of the vehicle window IoT system, and then transmitted to the computation gateway. The computation gateway may transmit a control parameter to the main control panel, acquire the display state collected by the image collection module, and compare the display state with a predetermined state in which the windowing module should be in accordance with the control parameter, so as to perform fault diagnosis.
In some possible embodiments of the present disclosure, the image collection module may include, but not limited to, a camera.
In some possible embodiments of the present disclosure, the image collection module may be coupled to the main control panel of the windowing device via a Universal Serial Bus (USB) interface, as shown in
In some possible embodiments of the present disclosure, the computation gateway is further configured to: transmit a testing picture to each control panel, and acquire, through the image collection module, a display state in which the testing picture is displayed by the transparent display panel of the windowing device; and perform fault diagnosis in accordance with the testing picture and the display state.
The fault of the windowing device may be preliminarily detected through the image collection module. For example, when such a phenomenon as flickering screen, black screen or white screen occurs for the transparent display panel, the display state of the windowing device may be acquired by the image collection module (e.g., the camera arranged at a position facing the windowing device), and then uploaded to the computation gateway. The computation gateway may determine the state of the windowing device in accordance with preset image or video information. When the current display state of the windowing device is inconsistent with a preset image, the computation gateway may preliminarily determine that a fault occurs for the windowing device, and further transmit a standard image to the windowing device. The windowing device may display the standard image, and the camera may acquire a display state of the windowing device that displays the standard image again and transmit it to the computation gateway for comparison. When the detected display state is inconsistent with the standard image, the computation device may determine that the fault occurs for the windowing device, and report the fault to the cloud server.
Through the above-mentioned detection ode, it is also able to detect a transmission fault for the communication module. The communication module may be in a wired or wireless transmission mode. Regardless of the transmission mode, when the windowing device fails to receive image data or the received image data is incorrect, the camera may collect image information, and report it to the computation gateway, and the computation gateway may issue data about the standard image again. When the windowing device still fails to receive the image data and fails to display the standard image, the computation gateway may also report the fault to the cloud server.
In the embodiments of the present disclosure, whether each board card operates normally may be determined in accordance with the display state collected by the image collection module in conjunction with a fault detection result acquired by the fault detection module.
For example, when a power source module for each board card operates normally depending on the fault detection result acquired by the fault detection module and a black screen state has been collected by the image collection module, a display screen fault may be reported to the cloud server. When the power source module for each board card operates normally depending on the fault detection result acquired by the fault detection module and the image data is transmitted by a transmitting end normally but the windowing device fails to receive any signal, a communication board fault may be reported to the cloud server. In a word, it is able to not only report the fault roughly, but also locate the board card fault within a smaller range.
According the windowing system in the embodiments of the present disclosure, on the basis of an Internet of Vehicle (IoV) in conjunction with a communication line for the train, bullet train or subway to which the windowing device is applied, it is able to discover, analyze and report the fault of the smart vehicle window using a wired or wireless technology in combination with an edge computation gateway.
The above embodiments are for illustrative purposes only, but the present disclosure is not limited thereto. Obviously, a person skilled in the art may make further modifications and improvements without departing from the spirit of the present disclosure, and these modifications and improvements shall also fall within the scope of the present disclosure.
