The first outer layer 30, the first substrate 40, the second substrate 60, and the second outer layer 70 are transparent layers made of transparent material. For example, the first outer layer 30 and the second outer layer 70 are glass layers, typically rigid structures, but may be flexible in some particular application requirements; the first and second substrates 40 and 60 may be formed of one of flexible materials of Polycarbonate (PC), polyethylene terephthalate (PET), or Triacetylcellulose (TAC).
Referring to fig. 2, a plurality of first conductive strips 41 are disposed on the first substrate 40 at intervals, and a plurality of second conductive strips 61 are disposed on the second substrate 60 and are staggered with respect to the first conductive strips 41, so that the first substrate 40 and the second substrate 60 form a grid-shaped electrode pair on two sides of the liquid crystal layer 50. In a preferred embodiment of the window glass 100, the first conductive strips 41 and the second conductive strips 61 are vertically staggered, and the first conductive strips 41 on the first substrate 40 and the second conductive strips 61 on the second substrate 60 are uniformly spaced, so that the grid-shaped electrode pairs formed on both sides of the liquid crystal layer 50 are uniformly distributed; of course, in other embodiments, the first conductive strips 41 and the second conductive strips 61 may also be disposed in a non-perpendicular staggered manner, and the first conductive strips 41 and the second conductive strips 61 may also be disposed in a non-equidistant spacing arrangement. It should be noted that the figures are only schematic diagrams of the first substrate 40, the liquid crystal layer 50 and the two conductive layers, and in practice, the number of the first conductive strips 41 and the second conductive strips 61 may be greater, and the distribution density may be greater. Of course, first conductive strips 41 and second conductive strips 61 are formed of a transparent conductive material, such as indium tin oxide ITO or nano silver.
Wherein the controller 10 is electrically connected to each of the first conductive strips 41 and each of the second conductive strips 61, the controller is in signal connection (i.e., electrically connected or wirelessly connected) with the adjusting device 20, the controller 10 determines a dimming area according to an input signal of the adjusting device 20, and applies corresponding dimming voltage signals to two sides of a portion of the liquid crystal layer 50 opposite to the dimming area to adjust a brightness state of the dimming area. By operating the adjusting device 20, the adjusting device 20 generates a corresponding electrical signal and inputs the electrical signal to the controller 10, the controller 10 determines a dimming region corresponding to the input signal according to the input signal of the adjusting device 20, identifies each of the first conductive strips 41 and each of the second conductive strips 61 corresponding to the dimming region according to the position of the dimming region, applies the corresponding electrical signal to each of the identified first conductive strips 41 and each of the identified second conductive strips 61 (i.e. applies a dimming voltage signal to the pair of electrodes corresponding to the dimming region), applies the dimming voltage signal to both sides of the portion of the liquid crystal layer 50 opposite to the dimming region, and changes the states of all liquid crystal cells of the portion of the liquid crystal layer 50 opposite to the dimming region, thereby changing the transmittance of the portion of the liquid crystal layer 50 opposite to the dimming region, i.e. changing the bright and dark states of the dimming region.

The user can operate the adjusting device 20 according to the requirement, so that the adjusting device 20 generates a corresponding electric signal to be input to the controller 10, the controller 10 determines a corresponding dimming region according to the input signal of the adjusting device 20, and then applies a dimming voltage signal to the electrode pair corresponding to the determined dimming region, so as to apply the dimming voltage signal to both sides of the part of the liquid crystal layer 50 opposite to the dimming region, so as to adjust the bright and dark states of the dimming region; therefore, the problem that the brightness of different areas of the window glass 100 cannot be adjusted independently is effectively solved, and more requirements of users are better met.
Further, referring to fig. 3, in an embodiment, the adjusting device 20 includes a first adjusting knob 21, and the controller 10 determines the corresponding dimming region according to a rotation amount signal of the first adjusting knob 21. For example, the first adjusting knob 21 may have a plurality of gears, when the first adjusting knob 21 is rotated to different gears, the magnitude of the rotation amount signal (e.g., voltage signal) output to the controller 10 is different, and the controller 10 determines the dimming areas at different positions or different magnitudes according to the received voltage signals with different magnitudes. For another example, each angular position to which the first adjusting knob 21 is rotated corresponds to a rotation quantity signal, the voltage of the rotation quantity signal gradually changes along with the rotation angle of the first adjusting knob 21, and the controller 10 determines the dimming regions at different positions or different sizes according to the received rotation quantity signals with different voltage magnitudes.
Referring to fig. 5 and 6, for example, in an example, the first adjusting knob 21 has a plurality of shift positions, wherein when the first adjusting knob 21 is rotated to the first shift position, the second shift position, and the third shift position, the controller 10 correspondingly determines that the I region, the II region, and the III region of the window glass 100 are dimming regions, respectively; when the first adjusting knob 21 is rotated to the zero gear position, no signal is output to the controller 10 by the adjusting device 20, and no darkened area exists on the window glass 100; when the first dial knob 21 is rotated to the fourth gear, the fifth gear, and the sixth gear, respectively, the controller 10 determines the regions I and II, the regions II and III, and the entire region of the window glass 100 as the dimming region, respectively.
Further, referring to fig. 4, in an embodiment, the adjusting device 20 includes a plurality of first dimming keys 22, and the controller 10 determines the corresponding dimming region according to a key signal of one first dimming key 22. For example, the key signal is a voltage signal generated after the first dimming key 22 is pressed, the voltage of the voltage signal generated after each first dimming key 22 is pressed is different, and the controller 10 determines the corresponding dimming area according to the voltage of the received key signal; for another example, the key signal is a high level signal generated after the first dimming key 22 is pressed, the first dimming keys 22 are electrically connected to the plurality of input terminals of the controller 10 in a one-to-one correspondence manner, when a user presses one of the first dimming keys 22, the input terminals of the controller 10 corresponding to the first dimming key 22 receive the high level signal, and the controller 10 determines the corresponding dimming area according to the input terminal of the received high level signal. Alternatively, in the present embodiment, the controller 10 determines the corresponding dimming region according to a combination of key signals of the plurality of first dimming keys 22; for example, the key signal is a high level signal generated after the first dimming key 22 is pressed, the plurality of first dimming keys 22 are electrically connected to the plurality of input terminals of the controller 10 in a one-to-one correspondence manner, when the user presses the plurality of first dimming keys 22, the controller 10 receives the high level signal from the plurality of input terminals corresponding to the plurality of pressed first dimming keys 22, and the controller 10 determines the corresponding dimming region according to a combination of the input terminals of the received high level signal.
Referring to fig. 5 and 6, for example, in an example, the adjusting device 20 includes three first dimming keys 22, wherein when the first dimming key 22, the second dimming key 24 and the third dimming key are pressed, the controller 10 correspondingly determines the I region, the II region and the III region of the window glass 100 as dimming regions; when none of the first dimming keys 22 is pressed, the regulator 20 outputs no signal to the controller 10, and there is no darkened area on the window glass 100; when all of the three first dimming keys 22 are pressed, the controller 10 determines that the entire area of the window glass 100 is a dimming area.
Further, referring to fig. 3, in the present embodiment, the controller 10 further determines the magnitude of the dimming voltage signal according to the input signal of the adjusting device 20. The user operates the adjusting device 20 to make the adjusting device 20 generate a corresponding electric signal to be input to the controller 10, and the controller 10 determines the magnitude of the dimming voltage signal corresponding to the input signal according to the input signal of the adjusting device 20, so that the dimming voltage signal with the determined magnitude is applied to both sides of the portion of the liquid crystal layer 50 opposite to the dimming region. The greater the voltage of the dimming voltage signal applied to both sides of the portion of the liquid crystal layer 50 opposite to the dimming region, the lower the transmittance of the portion of the liquid crystal layer 50 opposite to the dimming region, and the heavier the dimming degree, so that the user can not only select the dimming region of the window glass 100 by operating the adjusting device 20, but also control the dimming degree of the dimming region, and can better meet more requirements of the user.
Further, in an embodiment, the adjusting device 20 further includes a second adjusting knob 23, and the controller 10 determines the magnitude of the dimming voltage signal according to a rotation amount signal of the second adjusting knob 23. For example, the second adjustment knob 23 may have a plurality of gears, when the second adjustment knob 23 is rotated to different gears, the rotation amount signal (e.g., voltage signal) output to the controller 10 is different in magnitude, and the controller 10 determines the dimming voltage signal with different voltage magnitudes according to the received voltage signals with different voltage magnitudes. For another example, each rotated angle position of the second adjusting knob 23 corresponds to a rotation amount signal, the voltage of the rotation amount signal gradually changes along with the rotation angle of the second adjusting knob 23, and the controller 10 determines the dimming voltage signals with different voltages according to the received rotation amount signals with different voltages.
Further, referring to fig. 4, in an embodiment, the adjusting device 20 further includes a plurality of second dimming keys 24, and the controller 10 determines a corresponding dimming voltage signal according to a key signal of one of the second dimming keys 24; for example, the key signal is a voltage signal generated after the second dimming key 24 is pressed, the voltage of the voltage signal generated after each second dimming key 24 is pressed is different, and the controller 10 determines the dimming voltage signal corresponding to the voltage according to the voltage of the received key signal; for another example, the key signal is a high level signal generated after the second dimming key 24 is pressed, the plurality of second dimming keys 24 are electrically connected to the plurality of input terminals of the controller 10 in a one-to-one correspondence manner, when the user presses one of the second dimming keys 24, the input terminals of the controller 10 corresponding to the second dimming key 24 receive the high level signal, and the controller 10 determines the corresponding dimming voltage signal with the preset magnitude according to the input terminal of the received high level signal. Alternatively, in the present embodiment, the controller 10 determines the corresponding dimming voltage signal according to a combination of the key signals of the plurality of second dimming keys 24; for example, the key signal is a high level signal generated after the second dimming key 24 is pressed, the plurality of second dimming keys 24 are electrically connected to the plurality of input terminals of the controller 10 in a one-to-one correspondence manner, when the user presses the plurality of second dimming keys 24, the controller 10 receives the high level signal from the plurality of input terminals corresponding to the plurality of pressed second dimming keys 24, and the controller 10 determines the corresponding dimming voltage signal with the preset magnitude according to a combination of the input terminals of the received high level signal.
Further, referring to fig. 7 (the controller 10 and the adjusting device 20 are not shown in this figure), in the present embodiment, the corner of the window glass 100 is provided with the accommodating portion 101, and the controller is installed in the accommodating portion 101 (i.e., the controller 10 is embedded in the window glass 100). By the controller 10 being embedded in the glazing 100, the connection between the controller 10 and each of the first and second bus bars 41, 61 is built-in, simplifying the wiring.
Further, in the present embodiment, a photovoltaic cell assembly (not shown in the figure) for supplying power to the controller 10 is disposed thereon. The photovoltaic cell assembly includes a cell portion for supplying power to the controller 10 and a photovoltaic charging portion for charging the cell portion with ambient light to store energy. Therefore, the photovoltaic new energy mode can be adopted for power supply, and energy conservation and environmental protection are realized.
Further, referring to fig. 8, the photovoltaic cell assembly 80 includes a photovoltaic power generation module 81 and an energy storage module 82, and an output terminal of the photovoltaic power generation module 81 is electrically connected to a charging terminal of the energy storage module 82 to store the converted electric energy into the energy storage module 82. The photovoltaic power generation module 81 absorbs ambient light, converts light energy into electric energy and outputs the electric energy to the energy storage module 82, and charges the energy storage module 82; the energy storage module 82 stores the electric energy output by the photovoltaic power generation module 81 for the controller 10 to supply power.
Wherein, the detection end of the controller 10 is electrically connected to the output end of the photovoltaic power generation module 81 to detect the voltage of the output end of the photovoltaic power generation module 81; in the automatic dimming mode, the controller 10 determines the intensity of the ambient light according to the voltage of the detection terminal, and determines the corresponding dimming mode according to the intensity of the ambient light in a preset manner to perform dimming.
Since the magnitude of the electric energy converted by the photovoltaic power generation module 81 (which can be known from the magnitude of the output voltage at the output end thereof) is in a proportional relationship with the amount of light incident on the photovoltaic power generation module 81, in this embodiment, the voltage magnitude at the output end of the photovoltaic power generation module 81 is detected by the detection end of the controller 10, so that the intensity level of the ambient light can be determined, and then the controller 10 determines the corresponding dimming mode according to the determined intensity of the ambient light in a preset manner to perform dimming. The preset manner may be a preset mapping relationship between the intensity of the ambient light and the dimming mode, for example, the intensity levels 1 to 5 of the ambient light correspond to the dimming modes 1 to 5, respectively. The dimming mode comprises the position of the dimming area and the magnitude of the dimming voltage signal, namely the dimming mode is determined, namely the position of the dimming area and the magnitude of the dimming voltage signal applied to the dimming area are determined, so that the bright and dark states of the area corresponding to the window glass are adjusted.
Further, the controller 10 turns off the automatic dimming mode when receiving an input signal of the adjusting device 20. That is, the manual dimming mode is prioritized over the automatic dimming mode, and the automatic dimming mode does not interfere with the manual dimming performed by the user-friendly adjustment device. Of course, the controller 10 may switch to the automatic dimming mode upon detecting that the adjustment device 20 is off or no signal.
