Description

Technical Field

[0001] The present invention relates to the technical field of display screen touch control, and in particular to a method, system and electronic cigarette for realizing full-screen touch on a display light array. Background Art

[0002] With the development of electronic technology, especially in the field of e-cigarette applications, the development of display functions has gone through single LED (Light Emitting Diode) lights, LED light groups, digital tubes, TFT (Thin Film Transistor) displays, and even various star-shaped screens or 3D curved displays composed of LED dot matrix screens. The so-called dot matrix screen uses multiple small dots to represent information. Each small dot can emit a light signal by controlling the corresponding light-emitting diode or light-emitting tube to generate different information such as text, pictures, animations, etc. The number of LED lights in the entire display ranges from dozens to hundreds, and the colors can be single-color or multi-color LED lights composed of three-color LEDs.

[0003] As for the input and interactive functions of e-cigarettes, traditional LED-display e-cigarettes generally use physical buttons or wave switches for powering on and off, setting functions, and switching displayed information. However, these cannot directly implement touch functions on the LED display light array. To achieve touch functions on the LED display light array, some e-cigarette products directly transplant the touch screen solution from the TFT display screen and add a touch screen module ITO sensor (Indium Tin Oxide sensor). This module consists of an ITO sensor and a self-capacitive touch screen chip. This can achieve high-precision touch and gesture functions across the entire LED light display area.

[0004] While touchscreens can enable precise touch input on e-cigarette LED arrays, the overall cost is relatively high. Furthermore, touchscreen modules composed of ITO sensors cannot be bent, making them unsuitable for e-cigarette applications. This is because typical e-cigarette LED dot matrix displays are designed using flexible printed circuit (FPC) boards, which need to be bent into two 90-degree angles to create a three-sided display, making touchscreen design difficult.

[0005] The display screen composed of LED light arrays has a low pixel count, and the number of lights is generally less than 200. The touch screen solution using TFT display screen generally has more than tens of thousands of pixels, and the resolution is also not matched.

[0006] Therefore, there is an urgent need for a new technical solution that can accurately implement full-screen touch input function on various numbers of LED light arrays without using a touch screen module. Summary of the Invention

[0007] The present invention aims to provide a method, system, and electronic cigarette for implementing full-screen touch on a display light array, thereby enabling precise full-screen touch input on a variety of LED light arrays without the use of a touchscreen module. The various technical effects achieved by the preferred technical solutions provided by the present invention are detailed below.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] The present invention provides a method for implementing full-screen touch on a display light array, comprising the following steps:

[0010] Divide the display light array into multiple areas and configure multiple touch sensing channels in each area;

[0011] According to the lighting mode of the display light array and the divided multiple areas, the display light array and the multiple touch sensing channels are divided into multiple scanning areas respectively;

[0012] According to the lighting mode of the display light array, a signal transmission port is configured for each display light and touch sensing channel in each scanning area;

[0013] In the signal scanning stage, when a certain scanning area is in the touch signal scanning stage, the driving signal of the display light in the scanning area is switched to the touch scanning synchronization signal, and the display lights in other scanning areas that are not in the touch signal scanning stage are lit by the driving signal;

[0014] The display light array and the touch sensing channel are arranged on the same substrate.

[0015] In some embodiments, the pattern shape of each touch sensing channel is a triangular sawtooth shape, and each sawtooth tip of the triangular sawtooth is arranged between two rows of display lights or between two columns of display lights in a corresponding area.

[0016] In some embodiments, the display light array is divided into n regions in the row direction, and each region is provided with m touch sensing channels in the column direction; the n×m touch sensing channel regions and the region between each touch sensing channel and its adjacent touch sensing channel form 2m-1 coordinate segments in the row direction and 2n-1 coordinate segments in the column direction;

[0017] The touch position of the contact object on the display light array or the sensing position of the suspended sensing object is determined based on the (2m-1)×(2n-1) coordinate points, the data of the n×m touch sensing channels, and the data ratio of adjacent touch sensing channels.

[0018] In some embodiments, the n divided areas are divided into two upper and lower scanning areas, and the n×m touch sensing channels are divided into two upper and lower scanning areas.

[0019] In some embodiments, the display light array and the touch sensing channel adopt a double-layer structure, the display light array and the touch sensing channel are on the same layer, and the traces of the touch sensing channel and the display light traces of the display light array are on another layer corresponding to the touch sensing channel layer;

[0020] The touch signal channel wiring is connected to the touch sensing channel of the corresponding area through the through hole, and the display light wiring is connected to the display light of the corresponding area through the through hole.

[0021] In some embodiments, the lighting mode includes a forward and reverse push mode. According to the forward and reverse push mode, configuring signal transmission ports for multiple scanning areas of the display light array includes the following steps:

[0022] The display lights in each scanning area form an i×j array, with i+1 signal transmission ports arranged in sequence from row to row; the positive or negative pole of the display lights in each column is connected to a signal transmission port, and its negative or positive pole is connected in sequence to i signal transmission ports that are not connected to other display lights; the positive or negative pole of the display lights between each column is connected to different signal transmission ports; where i=j or j=i+1.

[0023] In some embodiments, the touch scan synchronization signal and the touch scan signal have the same frequency, voltage, timing, and phase.

[0024] As a common inventive concept, the present invention further provides a system for implementing full-screen touch on a display light array, for implementing the above-mentioned method for implementing full-screen touch on a display light array, comprising a main control chip, at least one driver chip connected to the main control chip, a display light array, and a touch sensing channel located on the same substrate as the display light array;

[0025] The display light array and touch sensing channel are divided into multiple scanning areas respectively. The display light in each scanning area is connected to the driver chip, and the touch sensing channel in each scanning area is connected to the main control chip.

[0026] During the signal scanning stage, the main control chip obtains the touch signals of the touch sensing channels of each scanning area in turn through the touch sensing channels, starts the corresponding touch function according to the obtained touch signals, and transmits the timing signals of each scanning area in the touch signal scanning stage to the driver chip; the driver chip switches the driving signal of the display light in the scanning area in the touch signal scanning stage to the touch scanning synchronization signal according to the timing signal of the touch signal scanning stage obtained, and lights up the display lights in other scanning areas that are not in the touch signal scanning stage through the driving signal.

[0027] In some embodiments, the driving chip includes a switch array, a SEG module, a PWM control module, a constant current control module, a random access memory, a CMD register, and a communication interface; the switch array includes a display light driving signal output terminal, a touch scan synchronization signal input terminal, and a SEG signal input terminal, the touch scan synchronization signal input terminal is connected to the main control chip, the SEG signal input terminal is connected to the SEG module, and the display light driving signal output terminal is connected to the display light array; the PWM control module and the constant current control module are both connected to the SEG module, the SEG module is connected to the random access memory and the CMD register, and the random access memory and the CMD register are connected to the communication interface.

[0028] As a common inventive concept, the present invention further provides an electronic cigarette, comprising the above-mentioned system for realizing full-screen touch on a display light array, and the above-mentioned method for realizing full-screen touch on a display light array is realized by the system.

[0029] Implementing one of the above technical solutions of the present invention has the following advantages or beneficial effects:

[0030] The present invention provides corresponding touch patterns on a substrate having a display light array, thereby realizing touch and gesture sensing functions in the display area of ​​the entire curved (e.g., curved into three sides) display light array without the need for a touch screen module, which can greatly reduce development costs.

[0031] In addition, the present invention divides the display light array and touch pattern into multiple scanning areas. When a certain scanning area is performing a touch signal scan, the display light drive signal control pin corresponding to the scanning area is switched to a touch scan synchronization signal inside the chip. All the display light control pins in the scanning area have the same frequency, voltage, timing, and phase as the touch scan signal, so that the display lights and corresponding wiring will not interfere with the touch sensing channel and increase the capacitance load. When a certain scanning area is in the touch signal scanning stage, the display light corresponding to the scanning area has no drive signal, while the display lights in the scanning area that is not in the touch signal scanning stage are lit by the drive signal. In this way, the interference of the on and off flickering of the display lights on the touch signal can be eliminated from the space of the display screen. As a result, the display area of ​​the display light array realizes high-precision touch and gesture functions. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the objects, technical solutions and advantages of the present invention clearer, the various exemplary embodiments to be described below will refer to the corresponding drawings, which constitute a part of the exemplary embodiments, in which various exemplary embodiments that may be used to implement the present invention are described. Unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present disclosure. It should be understood that they are only examples of processes, methods and devices that are consistent with some aspects of the present disclosure as detailed in the appended claims, and other embodiments may also be used, or structural and functional modifications may be made to the embodiments listed herein without departing from the scope and essence of the present invention.

[0045] In the present description, the term "plurality" means two or more. The terms "connected" and "connection" should be broadly interpreted, and may include, for example, fixed connection, detachable connection, integral connection, mechanical connection, electrical connection, communication connection, direct connection, indirect connection via an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in the present description based on specific circumstances.

[0046] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below, in which only the parts related to the embodiment of the present invention are shown.

[0047] Example 1: Figure 1 As shown, a method for implementing full-screen touch on a display light array in this embodiment includes the following steps:

[0048] S100, dividing the display light array into multiple areas, and configuring multiple touch sensing channels in each area;

[0049] S200, dividing the display light array and the plurality of touch sensing channels into a plurality of scanning areas according to the lighting mode of the display light array and the plurality of divided areas;

[0050] In an optional implementation, the scanning area of ​​the display light array and the scanning area of ​​the touch sensing channel have the same number and partitioning criteria;

[0051] S300, configuring a signal transmission port for each display light and touch sensing channel in each scanning area according to the lighting mode of the display light array;

[0052] S400, in the signal scanning phase, when a scanning area is in the touch signal scanning phase, switching the driving signal of the display light in the scanning area to the touch scanning synchronization signal, and lighting the display lights in other scanning areas that are not in the touch signal scanning phase through the driving signal;

[0053] The display light array and touch sensing channels are placed on the same substrate, which can be an FPC (Flexible Printed Circuit) or a PCB (Printed Circuit Board).

[0054] Understandably, designing a display light array (such as an LED light array) and touch sensing channels on the same FPC or PCB board requires addressing two issues: 1) The flickering of the LED lights on and off significantly interferes with the touch sensing channels at that location; and 2) the touch pattern formed by the touch sensing channels is incomplete due to the arrangement of the lights, affecting the data accuracy and sensitivity of the touch sensing coordinates.

[0055] The touch sensing channel is a structure that can realize touch or air sensing, and can generate capacitance or self-capacitance when powered on or when human body is in contact or close. For example, the metal filament, metal base, lamp housing and wiring connecting the display light of the display light constitute a sensor that can sense changes in external self-capacitance. By setting a touch sensing channel in the above structure, a specific pattern shape is formed, and the change in this capacitance is detected by the self-capacitance detection unit inside the chip. When it exceeds the preset threshold, it can be determined that a touch or air action has occurred. Then, the function of touch or suspended touch is realized directly on the display light array. Of course, the touch sensing channel can also be copper foil, etc.

[0056] Based on this, the present invention implements touch and gesture sensing functionality across the entire display area of ​​a display light array (particularly, a three-sided curved electronic cigarette display light array) by providing corresponding touch patterns on a substrate with a display light array, without requiring a touchscreen module. This significantly reduces development costs. Furthermore, the display light array and touch patterns are divided into multiple scanning areas. When a scanning area is performing a touch signal scan, the corresponding display light drive signal control pin is internally switched to a touch scan synchronization signal within the chip. All display light control pins within that scanning area have the same frequency, voltage, timing, and phase as the touch scan signal. This prevents the display lights and corresponding traces from interfering with the touch sensing channel or increasing capacitive loading. Furthermore, when a scanning area is in the touch signal scanning phase, the corresponding display light is deactivated, while the display lights in other scanning areas not in the touch signal scanning phase are illuminated by the drive signal. This eliminates interference from the flickering of the display lights on and off on the touch signal within the display screen. Consequently, the display area of ​​the display light array achieves highly precise touch and gesture functionality.

[0057] Based on the above embodiment, the pattern shape of each touch sensing channel is a triangular sawtooth shape, and each sawtooth tip of the triangular sawtooth is arranged between two rows of display lights or two columns of display lights in the corresponding area, thereby ensuring the integrity and consistency of the touch sensing channel pattern.

[0058] Based on the above embodiment, the display light array is divided into n regions in the row direction, and each region is provided with m touch sensing channels in the column direction. Here, n and m are both positive integers greater than 2. The n×m touch sensing channel regions and the region between each touch sensing channel and its adjacent touch sensing channel form 2m-1 coordinate segments in the row direction and 2n-1 coordinate segments in the column direction. Based on the (2m-1)×(2n-1) coordinate points, the data from the n×m touch sensing channels and the data ratio of adjacent touch sensing channels are used to determine the touch position of a contact object on the display light array or the sensing position of a suspended sensing object.

[0059] like Figure 2 As shown, in a specific embodiment, the full-screen touch function is realized on the 144 LED light array of the electronic cigarette as an example. In the display area, the LED lights are evenly distributed to form the dot matrix pixels of the display. There are 12 LED lights in a horizontal row and 12 rows vertically, with a total of 12×12=144 LED lights. This 144 LED dot matrix is ​​the display pixel of the display area. The design of the touch sensing channel is that the entire display area is divided into 4 areas in the vertical direction, and each area has 3 touch signal channels in the horizontal direction (such as Figure 2 The LED array is divided into four zones along the rows, each with three touch signal channels. These zones are separated by a triangular sawtooth pattern, with the sharpest portion of the sawtooth located between the upper and lower rows of LEDs. This ensures the integrity and consistency of the touch sensing channels.

[0060] It is understandable that if the top of the sawtooth is not placed in the middle of the upper and lower rows of LED lights, it may be interrupted by the position of the LED lights, resulting in an incomplete pattern. If the interruption position of each channel is different, it will lead to differences in the sensing area of ​​each channel, that is, poor consistency. Furthermore, because the display light and the touch sensing channel are designed on the same board, the display light will cause the touch sensing channel area to be reduced and the touch sensing channel to be incomplete. It is adjusted to a horizontal design of three touch sensing channels, with two pairs of triangular patterns in the horizontal direction. The area detected by each pair of patterns is half of the original two pairs of touch sensing channel design, thereby greatly improving the accuracy of touch detection.

[0061] It should be noted that the 12×12 display light array can be numbered from left to right and from top to bottom, for example, row 1: D1, D2, ..., D12; row 2: D13, D14, ..., D24, ...; row 12: D133, D134, ..., D144. The following description of dividing the display light array into regions and the division of the display lights into scanning zones can both be based on the LED numbering described here.

[0062] like Figure 3 As shown, the sawtooth design can further determine the horizontal coordinate based on the data characteristics of the three touch sensing channels. The horizontal coordinate is determined by three (m=3) touch sensing channels. The three touch signal channels can be divided into five coordinate segments through pattern design. When a finger touches the position between S1 and S2, the data of S1 and S2 are close. In the vertical coordinate direction, four (n=4) touch sensing channels form seven position coordinate segments. When a finger touches the position between S1 and S4, the data of S1 and S4 are close. The touch signal channel data and ratio can be used to determine the touch position of the finger.

[0063] It is understandable that the sawtooth design can divide the data characteristics of the three touch sensing channels into more than 5 levels: S1, S1 / S2, S2, S2 / S3, and S3. Similarly, the vertical touch sensing channels can be configured into 7 using software algorithms, so that the touch area can become 7×5=35, 144 lights, 35 touch areas, and each area is 144 / 35=4.1, that is, each area has about 4 lights, and the area of ​​4 lights is about 4mm×6mm. Generally, the area of ​​a normal finger is 40 square millimeters, so when a finger slides across the display area, the lights in the corresponding area light up, thus achieving the effect of touch and gesture.

[0064] Based on the above embodiment, the display light array and touch sensing channel adopt a dual-layer structure. The display light array and touch sensing channel are located on the same layer, while the touch sensing channel traces and the display light traces of the display light array are located on a separate layer from the touch sensing channel layer. The touch signal channel traces are connected to the touch pattern (touch sensing channel) in the corresponding area through through-holes, and the display light traces are connected to the display lights in the corresponding area through through-holes. It can be understood that using a dual-layer design can reduce costs compared to designs with more than two layers.

[0065] Based on the above embodiment, the lighting mode includes forward and reverse push modes. According to the forward and reverse push modes, configuring signal transmission ports for multiple scanning areas of the display light array includes the following steps:

[0066] The display lights in each scanning area form an i×j array, with i+1 signal transmission ports arranged in sequence from row to row; the positive or negative pole of the display lights in each column is connected to a signal transmission port, and its negative or positive pole is connected in sequence to i signal transmission ports that are not connected to other display lights; the positive or negative pole of the display lights between each column is connected to different signal transmission ports; where i=j or j=i+1.

[0067] like Figure 4-8 As shown, at the software control level, the four-zone display light array is divided into two upper and lower scanning zones. The LED light array uses a forward and reverse scanning mode, with 72 LEDs in each of the upper half (LED1 group, LEDs numbered D1-D72) and lower half (LED2 group, LEDs numbered D73-D144). Within LED1 group, an 8×9 (i=8, j=9) array is formed, with signal transmission ports OUT1 through OUT9 arranged in row order (signal transmission ports OUT1 through OUT8 are connected to pins 24 through 17 of driver chip U2, respectively, and signal transmission port OUT9 is connected to pin 5 of driver chip U2). The positive or negative pole of each display light in each column is connected to a signal transmission port, and its negative or positive pole is connected sequentially to the eight signal transmission ports of the other unconnected display lights. The positive or negative pole of each display light in each column is connected to a different signal transmission port. In LED group 2, an 8×9 array is formed, with signal transmission ports OUT10 through OUT18 arranged in sequence along the rows (signal transmission ports OUT10 through OUT16 are connected to pins 6 through 12 of driver chip U2, respectively; signal transmission port OUT17 is connected to pin 18 of driver chip U2; and signal transmission port OUT18 is connected to pin 17 of driver chip U2). The positive or negative pole of each indicator light in each column is connected to a signal transmission port, and its negative or positive pole is sequentially connected to the other eight signal transmission ports that are not connected to indicator lights. The positive or negative poles of the indicator lights between columns are connected to different signal transmission ports.

[0068] Furthermore, the 12 touch sensing channels are divided into two upper and lower scanning areas: TP Touch Group 1 and TP Touch Group 2, each with six touch sensing channels. Touch signal channels S1-S6 (touch signal channel S1 is connected to pin 2 of the main control chip U1, touch signal channel S2 is connected to pin 1 of the main control chip U1, and touch signal channels S3-S6 are connected to pins 36 to 33 of the main control chip U1, respectively) form the upper half, TP1 group. All LEDs within this area belong to LED1 group. The lower half, where touch sensing channels S7-S12 (touch signal channels S7-S12 are connected to pins 32 to 27 of the main control chip U1, respectively), form TP2 group. All LEDs within this area belong to LED2 group.

[0069] It should be noted that pin 18 of the main control chip U1 outputs the touch scan synchronization signal TP-SYNC, and pin 18 of the main control chip U1 is connected to pin 16 of the driver chip U2.

[0070] like Figure 9 The figure below shows a timing diagram for touch sensing channel scanning and LED array lighting (scanning phase). Designed with a 100Hz LED refresh rate, the LED1 and LED2 groups light up within 10ms. This 10ms period is further divided into two 5ms periods: LED1 lights up within the first 5ms, and LED2 lights up within the second 5ms. When the LED1 lamp group in the upper half is lit, the TP touch 1 group at its location does not work, and the TP touch 2 group in the lower half starts the detection work. The IO ports of the LED lamps at the location of the TP touch 2 group all output the same drive signals with the same frequency, voltage and timing as the TP touch 2 group scanning signals. This ensures that the TP touch 2 group is not affected by the interference of the LED lighting scanning and the load impedance during scanning; similarly, when the LED2 lamp group in the lower half is lit, the TP touch 2 group at its location does not work, and the TP touch 1 group in the upper half starts the detection work. The IO ports of the LED lamps at the location of the TP touch 1 group all output the same drive signals with the same frequency, voltage and timing as the TP touch 1 group scanning signals. This ensures that the TP touch 1 group is not affected by the interference of the LED lighting scanning and the load impedance during scanning.

[0071] Example 2: Figure 10-11 As shown, as the same inventive concept, this embodiment provides a system for implementing a touch function on a display light array, which is used to implement a method for implementing full-screen touch on a display light array as described in the first embodiment above, including a main control chip, at least one driver chip connected to the main control chip, a display light array, and touch sensing channels located on the same substrate as the display light array. The display light array and the touch sensing channels are respectively divided into multiple scanning areas, the display lights in each scanning area are connected to the driver chip, and the touch sensing channels in each scanning area are connected to the main control chip. Specifically, the display light array is divided into n areas in the row direction, and m touch sensing channels are provided in each area in the column direction. The n divided areas are divided into upper and lower scanning areas (such as the upper half of the display light array and the lower half of the display light array in the figure), and the n×m touch sensing channels are divided into upper and lower scanning areas (such as the upper half of the touch sensing channel and the lower half of the touch sensing channel in the figure).

[0072] Furthermore, during the signal scanning phase, the main control chip sequentially acquires touch signals from the touch sensing channels of each scanning area through the touch sensing channels, activates the corresponding touch function based on the acquired touch signals, and transmits the timing signals of each scanning area in the touch signal scanning phase to the driver chip. Based on the acquired timing signals of the touch signal scanning phase, the driver chip switches the drive signal for the display lights in the scanning area in the touch signal scanning phase to the touch scanning synchronization signal, and illuminates the display lights in other scanning areas that are not in the touch signal scanning phase through the drive signal.

[0073] Based on the above embodiment, the driver chip includes a switch array, an SEG module, a PWM control module, a constant current control module, a random access memory (RAM), a CMD register, and a communication interface. The switch array includes a display light drive signal output terminal, a touch scan synchronization signal input terminal, and an SEG signal input terminal. The touch scan synchronization signal input terminal is connected to the main control chip, the SEG signal input terminal is connected to the SEG module, and the display light drive signal output terminal is connected to the display light array. The PWM control module and the constant current control module are both connected to the SEG module, which is connected to the RAM and CMD register. The RAM and CMD register are then connected to the communication interface.

[0074] As a specific embodiment, Figure 7 This is a schematic diagram of the MCU (main control chip) architecture for implementing full-screen touch functionality on a 144-LED array. The MCU's GPIOs have touch functionality and can control the LED driver chip (driver chip) via SPI. During touch detection scanning, the MCU outputs a touch scan synchronization signal, TP_SYNC, to the LED driver chip. The LED driver chip controls the LEDs or outputs touch detection synchronization signals based on the timing provided by the MCU via SPI. The method for implementing full-screen touch functionality on a display light array in this embodiment is consistent with that described in Example 1 and is not further detailed here.

[0075] Furthermore, Figure 11 This is the internal circuit diagram of the driver chip. Compared with traditional driver chips, a switch array module is added. Each switch in the switch array can be turned on and off by the main control chip through the communication interface. The output SEG0-SEGn can control the flashing of the LED lights and can also switch to the touch scan synchronization signal TP_SYNC as needed. The driver chip adds a touch scan synchronization signal input interface, using the switch array to complete the switching between the LED control signal and the touch scan synchronization signal at the output pin of the driver chip.

[0076] It should be noted that the driver chip uses POR (Power On Reset) and LVR (Low Voltage Reset) reset mechanisms for chip startup and voltage detection.

[0077] Example 3: Based on the same inventive concept, this example provides an electronic cigarette, including the system for implementing a touch function on a display light array described in Example 2. The method for implementing full-screen touch on a display light array described in Example 1 is implemented by using the system for implementing a touch function on a display light array. For details, please refer to Examples 1 and 2, which will not be repeated here.

[0078] It should be noted that the display light array (display screen) of the electronic cigarette in this embodiment can be bent into three sides (for example, bent into two 90° angles for a three-sided display when in use), and the display area of ​​the entire display light array can realize touch and gesture sensing functions.

[0079] Furthermore, the main control chip is the main control chip of the electronic cigarette. When the number of LED lights in the electronic cigarette exceeds 200, an external driver chip (LED light driver chip) is generally required. The LED light driver chip has a constant current control function, which can control the light on and off and different levels of brightness. Based on cost considerations, the light array of the electronic cigarette generally adopts a forward and reverse lighting mode.

[0080] It should be understood that, although the steps in the flowcharts of the above embodiments are shown in sequence as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the processes of the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily to be performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
