[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The terms “first”, “second”, etc. used in this document do not specifically refer to an order or sequence, nor are they used to limit this application. They are merely used to distinguish components or operations described with the same technical terms.

[0023] In the first embodiment of this application, please refer to Figure 1, which is a decomposed schematic diagram of the intelligent movable regional touch dimming window of the first embodiment of the present application. The intelligent movable regional touch dimming window 1 of this embodiment is mainly used for the side windows of vehicles, such as high-speed rail side windows, subway side windows, urban rail train side windows, tram side windows, car side windows, ship side windows, etc. As shown in the figure, the intelligent movable regional touch dimming window 1 includes a cover glass 2, a touch screen 3 and a dimming functional part 4. In this embodiment, the cover glass 2 is the inner glass of the side window of the vehicle to which the intelligent movable regional touch dimming window 1 of this embodiment is applied. For example, the cover glass 2 can be the inner glass of the high-speed rail side window, or the cover glass 2 can also be the inner glass of the subway side window, but it is not limited thereto.

[0024] The touch screen 3 is disposed on the cover glass 2. In this embodiment, refer to Figure 1 , the touch screen 3 is bonded to one side of the cover glass 2 through the interlayer 5. Specifically, a interlayer structure is formed between the cover glass 2, the interlayer 5 and the touch screen 3. The cover glass 2, the interlayer 5 and the touch screen 3 are bonded together through the interlayer process, but not limited thereto. The touch screen 3 is configured to generate a first touch signal and a second touch signal. The first touch signal corresponds to a first gesture of the user on the touch screen 3, and the second touch signal corresponds to a second gesture of the user on the touch screen 3. In this embodiment, the touch screen 3 is a capacitive touch screen. The capacitive touch screen is a layer of transparent special metal conductive material attached to the glass surface. When a finger touches the metal layer, the capacitance of the contact point will change, so that the frequency of the oscillator connected thereto will change. By measuring the frequency change, the touch position can be determined to obtain information, so that the user's gesture on the capacitive touch screen is converted into an electrical signal, that is, a touch signal. The first gesture is a sliding track or a line of the user's finger on the capacitive touch screen, and the second gesture is a single point, a sliding track or a line of the user's finger on the capacitive touch screen, but not limited thereto.

[0025] The dimming function element 4 is disposed on the touch screen 3 and is electrically connected to the touch screen 3. In this embodiment, refer to Figure 1 The dimming function part 4 is connected to the display chip 6 through a communication cable, the touch screen 3 is connected to the touch chip 7 through a communication cable, and the touch chip 7 is connected to the display chip 6 through USB or RS232 communication, so as to realize the electrical connection between the dimming function part 4 and the touch screen 3. For details, please refer to Figure 2 , which is a schematic diagram of the working principle of the intelligent movable area touch dimming window of the first embodiment of the present application; as shown in the figure, the user operates the touch screen 3 with a touch gesture, the touch chip 7 recognizes the touch gesture and generates a touch signal, the display chip 6 receives the touch signal, and controls the optical function part 4 to display feedback. The dimming function part 4 includes one of dye liquid crystal, EC, NPD, PDLC, PNLC and LCD dimming liquid crystal, but is not limited thereto.

[0026] When dimming the intelligent movable area touch dimming window 1 of this embodiment, the user forms a first gesture in the corresponding area of ​​the touch screen 3 by touching and sliding any area of ​​the cover glass 2, and the first gesture forms a closed area. The touch screen 3 recognizes that there is a touch operation on its surface and generates a first touch signal, and sends it to the dimming function component 4. The dimming function component 4 generates a corresponding dimming area according to the first touch signal. This dimming area has the same position, shape and size as the closed area formed by the first gesture. Then the user forms a second gesture in the dimming area of ​​the touch screen 3 by touching the position corresponding to the dimming area of ​​the cover glass 2 again. The touch screen 3 recognizes that there is a touch operation on its surface again and generates a second touch signal. The dimming function component 4 controls the transparency of the dimming area according to the second touch signal, so that a closed area can be arbitrarily drawn on the cover glass 2 and the closed area can be dimmed separately. Moreover, when dimming the closed area, the dimming of other areas will not be affected, so that the dimming needs of different passengers can be met.

[0027] In the second embodiment of this application, please refer to Figure 3 Also see Figure 1 and Figure 2 , Figure 3 1 is a flow chart of the steps of the control method of the intelligent movable regional touch dimming window of the second embodiment of the present application. The control method S of the intelligent movable regional touch dimming window of this embodiment is the control principle of the intelligent movable regional touch dimming window of the first embodiment. As shown in the figure, the control method S of the intelligent movable regional touch dimming window includes the following steps S1-S4, wherein:

[0028] Step S1 : a first gesture is formed on the touch screen 3 . A first touch signal is generated on the touch screen 3 , the first touch signal corresponds to the first gesture of the user on the touch screen 3 , and is transmitted to the transparent dimming function element 4 .

[0029] Specifically, the user's finger forms a first gesture on the corresponding area of ​​the touch screen 3 by touching and sliding any area of ​​the cover glass 2. The touch chip 7 of the touch screen 3 recognizes that there is a touch operation on the surface of the touch screen 3 and generates a first touch signal. The touch chip 7 sends the first touch signal to the display chip 6 of the dimming function part 4 through USB or RS232 communication.

[0030] In this embodiment, the transparency level of the dimming function part 4 is divided into 0 to 5 levels, wherein the light shielding degree of the transparency level from 0 to 5 decreases in sequence. Level 0 is a black screen / opaque state with the highest light shielding degree, and level 5 is a white screen / transparent state with the lowest light shielding degree. When the overall transparency level of the dimming function part 4 is at any level of transparency from 0 to 2, the trajectory of the first gesture is white, and when the overall transparency level of the dimming function part 4 is at any level of transparency from 3 to 5, the trajectory of the first gesture is black, so that the trajectory of the first gesture forms a sharp contrast with the overall transparency of the dimming function part 4, thereby facilitating the user to observe the trajectory of the first gesture.

[0031] Step S2, forming a dimming area. The transparent dimming functional component 4 identifies the first touch signal, determines whether the area formed by the first gesture is a closed area, and if so, displays the dimming area corresponding to the first touch signal.

[0032] Specifically, the display chip 6 of the transparent dimming function part 4 identifies the first touch signal and determines whether the area formed by the first gesture is a closed area. In this embodiment, due to different operating habits of different users, it is difficult to draw a closed area by sliding a finger on the touch screen 3 at one time. Therefore, the transparent dimming function part 4 determines whether the area formed by the first gesture is a closed area based on whether the area formed by at least one first gesture on the touch screen 3 is a closed area. If the area formed by the first gesture is a closed area, the transparent dimming function part 4 is controlled to display the dimming area corresponding to the first touch signal, that is, the dimming area with the same position, shape and size as the area formed by the first gesture is displayed on the transparent dimming function part 4. After the transparent dimming function part 4 displays the dimming area, the initial transparency level of the dimming area is level 0, but it is not limited thereto.

[0033] Preferably, when there is a gap in at least one area formed by the first gesture, such as a gap caused by improper user operation, the display chip 6 of the transparent dimming function part 4 fills the gap after recognizing the first touch signal, so that the first gesture forms a closed area, and determines that the area formed by the first gesture is a closed area, that is, the dimming area desired by the user. If the transparent dimming function part cannot fill the gap, for example, the gap is large or the user accidentally touches the touch screen 3, the first gesture is deleted after a period of time, specifically according to the 15s no operation principle, that is, if the touch screen 3 is not operated within 15s, the first gesture / line on it will automatically disappear.

[0034] Preferably, when the transparent dimming functional part 4 determines that an area composed of at least one first gesture is a closed area, redundant lines outside the closed area disappear. Specifically, when the user draws a closed area by sliding his finger on the touch screen 3, there will usually be redundant lines around the closed area composed of the first gesture due to the user's irregular line drawing, such as extra lines formed by the intersection of two lines, lines that do not form a closed area, etc. After the transparent dimming functional part 4 determines that the area composed of the first gesture is a closed area, these redundant lines automatically disappear.

[0035] Step S3 , forming a second gesture on the touch screen 3 . The touch screen 3 generates a second touch signal and transmits it to the transparent dimming function element 4 . The second touch signal corresponds to the second gesture of the user on the touch screen 3 .

[0036] Specifically, the user's finger touches any position of the cover glass 2 to form a second gesture at the corresponding position of the touch screen 3, and the touch chip 7 of the touch screen 3 recognizes that there is a touch operation on the surface of the touch screen 3 and generates a second touch signal, and the touch chip 7 sends the second touch signal to the display chip 6 of the dimming function part 4 through USB or RS232 communication. The second gesture can be a single point of the user's finger on the touch screen 3, or it can be a sliding of the user's finger on the touch screen 3, but it is not limited to this.

[0037] Step S4, adjusting the transparency of the dimming area. The transparent dimming function element 4 identifies the second touch signal, determines whether the second gesture is within the dimming area, and if so, adjusts the transparency of the dimming area.

[0038] Specifically, the display chip 6 of the transparent dimming function part 4 recognizes the second touch signal, determines whether the second gesture is within the dimming area, and if so, adjusts the transparency of the dimming area. Each time the transparent dimming function part 4 determines that the second gesture is within the dimming area, the transparency level of the dimming area is increased by one level until the transparency level of the dimming area reaches level 5, thereby achieving arbitrary dimming of the dimming area, and the interval between two adjacent determinations that the second gesture is within the dimming area is preferably greater than 500ms, that is, the time interval between two adjacent adjustments of the transparency of the dimming area is greater than 500ms. When the user wants to cancel this dimming area, the user can press and hold the dimming area for more than 5s to restore this dimming area to the transparency level of the current transparent dimming function part 4.

[0039] In this embodiment, if the second gesture is within the dimming area and is in the form of a sliding drag, the dimming area is adjusted to the dragging position. For example, the incident angle of sunlight changes during the operation of the train. At this time, the dimming area previously set by the user may not be able to block the current sunlight. At this time, the user presses his finger anywhere in the dimming area, and then slides and drags to drag the dimming area to the position the user wants, so as to improve the user's riding experience and satisfaction.

[0040] In this embodiment, if the transparent dimming functional component 4 determines that the second gesture is not within the dimming area and the area formed by the second gesture is a closed area, it is determined that the user wants to add a new dimming area, and the dimming area corresponding to the second touch signal is displayed on the transparent dimming functional component 4, that is, a dimming area with the same position, shape and size as the area formed by the second gesture is displayed on the transparent dimming functional component 4, that is, the second gesture is regarded as the first gesture, and is processed according to the first gesture processing method. In this way, multiple dimming areas are divided simultaneously on the transparent dimming functional component 4, so that each dimming area can be dimmed separately, thereby meeting the dimming needs of different passengers.

[0041] In summary, the present application provides an intelligent movable area touch dimming window and its control method, which are mainly used for the side windows of vehicles. The touch screen and the dimming function part are set on the cover glass. The user's first gesture on the touch screen forms a closed area and controls the dimming function part to generate a corresponding dimming area. The user's second gesture on the touch screen is located in the dimming area and controls the transparency of the dimming area. In this way, a closed area can be arbitrarily drawn on the cover glass / dimming function part for separate dimming, and the transparency of other areas will not be affected while dimming the closed area, so that the dimming needs of different passengers can be met.
