[0068] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0069] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms “connected,” “linked,” or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0070] In this disclosure, "multiple or several" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0071] In related technologies, the color and brightness of the LED lights in smart display devices are often adjusted based on audio and / or the display screen. For example, adjustments are made based on audio volume, such as high-frequency sounds corresponding to deep blue, low-frequency sounds to deep red, and mid-frequency sounds to green or cyan, or a transitional color between the two. Adjustments are also made based on the display screen, such as adjusting the LED lights to illuminate the color with the highest proportion of the displayed image. For instance, the color and brightness might flash in response to music like "chicken cutlet." All of these adjustments are based on the audio and video provided by the display device, failing to achieve a vibrant color effect for human-computer interaction and resulting in a poor user experience.

[0072] In view of this, the present disclosure provides a colorful light control method, display device, computer equipment and storage medium, which essentially allows the colorful light to light up in real time following the user's position, realizing a human-computer interaction colorful light effect between the user and the colorful light.

[0073] Figure 1 A flowchart of a colorful light control method provided in this disclosure embodiment is shown below. Figure 1 As shown, it includes S11 to S13.

[0074] S11. Acquire the motion parameters of the user in front of the display device detected by the sensor.

[0075] For example, sensors can be millimeter-wave radar, depth cameras, time-of-flight (ToF) sensors, etc. Data collected by sensors is analyzed to determine the user's motion parameters.

[0076] Taking millimeter-wave radar as an example, motion parameters can include the distance from the user to the preset origin, the angle between the user and the normal perpendicular to the preset origin, and the user's movement speed. The preset origin can be the center of the sensor, the center of the screen, the midpoint of the top bezel of the screen, or the midpoint of the bottom bezel of the screen.

[0077] Using a depth camera or a time-of-flight (ToF) sensor as an example, motion parameters can include the user's actual position and speed of movement.

[0078] For example, the display device may be a television set, a conference all-in-one machine, or an educational device.

[0079] S12. Determine the user's motion status based on motion parameters.

[0080] Among them, the state of motion includes either motion or stillness.

[0081] Specifically, the user's motion state can be determined based on at least one of the following: the user's distance from the preset origin, the angle between the user and the normal perpendicular to the preset origin, and the user's motion speed.

[0082] For example, if the distance between the user and the preset origin remains unchanged in adjacent moments, the user's motion state is determined to be stationary; conversely, if the distance changes in adjacent moments, the user's motion state is determined to be moving. Similarly, if the angle between the user and the normal perpendicular to the preset origin remains unchanged in adjacent moments, the user's motion state is determined to be stationary; conversely, if the angle changes in adjacent moments, the user's motion state is determined to be moving. Likewise, if the user's speed remains unchanged in adjacent moments, the user's motion state is determined to be stationary; conversely, if the user's speed changes in adjacent moments, the user's motion state is determined to be moving.

[0083] S13. When the motion state is in motion, control the target colorful light corresponding to the current position to be lit according to the current position indicated by the motion parameters.

[0084] In one possible implementation, taking a millimeter-wave radar sensor as an example, when the motion parameters include the user's current distance and current angle, and the user is in motion, their current position is determined based on the current distance and current angle. Based on the current position, a target illuminated light corresponding to that position can be identified, and the target illuminated light can be controlled to illuminate.

[0085] In another possible implementation, when the motion parameters include the user's actual position, the user's actual position at the current moment is the user's current position. Based on the current position, a target illuminated light corresponding to the current position can be determined, and the target illuminated light can be controlled to illuminate.

[0086] Figure 2A This is an exemplary schematic diagram showing the current position corresponding to a target RGB light, provided for an embodiment of this disclosure. Figure 2B This is another exemplary schematic diagram of the current position corresponding to the target RGB light provided in this embodiment of the disclosure. For example, the current position is a spatial coordinate in the sensor coordinate system. Each RGB light 10 on the display device 100 is also recorded in the same sensor coordinate system and can have a uniquely corresponding spatial coordinate, such as... Figure 2A As shown, when the x-coordinate of the current position is the same as the x-coordinate of the dazzling light 10, that is, the dazzling light 10 is the target dazzling light (such as a target dazzling light) corresponding to the current position. Figure 2B As shown, if there is no colored light with the same x-coordinate as the current position, the colored light closest to the current position (such as colored light 10A and colored light 10B) or the colored light adjacent to the x-coordinate of the current position is taken as the target colored light corresponding to the current position (such as multiple target colored lights).

[0087] The color light control method provided in this embodiment uses a sensor to detect user motion parameters and determine the user's motion state. When the user is in motion, the target color light corresponding to the current position is controlled to light up according to the user's current position indicated by the motion parameters. This ensures that the color light lights up in real time following the user's position, thus realizing a human-computer interaction color light effect between the user and the color light.

[0088] In some embodiments, for the above S12, the motion parameters include the current motion speed, that is, the user's motion speed at the current moment. Taking a millimeter-wave radar as an example, the millimeter-wave radar includes one transmitting antenna and two receiving antennas; the process of determining the motion speed may include: determining the current motion speed based on the speed of light, the initial frequency of the transmitted signal of the transmitting antenna, the difference between the highest and lowest frequencies of the transmitted signal of the transmitting antenna, the frequency difference between the upward transmission and reception sweeps of the millimeter-wave radar, and the frequency difference between the downward transmission and reception sweeps of the millimeter-wave radar.

[0089] The current speed can be determined using Formula 1 below.

[0090] Formula 1: .

[0091] Where v represents the current speed; c represents the speed of light; and f0 represents the initial frequency of the transmitted signal from the transmitting antenna. This represents the difference between the highest and lowest frequencies of the transmitted signal from the transmitting antenna. This represents the frequency difference between the upward transmission and reception sweep frequencies of a millimeter-wave radar. This indicates the frequency difference between the downward transmission and reception sweep frequencies of the millimeter-wave radar.

[0092] Optionally, when the current speed is within a first preset speed range, the motion state is determined to be motion; when the current speed is within a second preset speed range, the motion state is determined to be stationary. The first speed within the first preset speed range is greater than the second speed within the second preset speed range, and the second preset speed range includes 0. The first preset speed range refers to the range greater than a preset speed, which can be 0.01 m / s or 0.02 m / s. The second preset speed range refers to the range less than or equal to a preset speed. Both the first and second speeds are positive numbers.

[0093] Motion parameters also include the current distance. The process of determining the current distance may include: determining the current distance based on the speed of light, the difference between the highest and lowest frequencies of the millimeter-wave radar's transmitted signal, the frequency difference between the upward transmission and reception sweeps of the millimeter-wave radar, the frequency difference between the downward transmission and reception sweeps of the millimeter-wave radar, and the frequency of the sweep signal of the millimeter-wave radar.

[0094] The current distance can be determined using Formula 2 below.

[0095] Formula 2: , .

[0096] in, This indicates the frequency of the swept signal of the millimeter-wave radar. Increasing the swept bandwidth can reduce the range resolution. Indicates the frequency sweep period; Indicates the current distance; c represents the speed of light; This represents the difference between the highest and lowest frequencies of the transmitted signal from the transmitting antenna. This represents the frequency difference between the upward transmission and reception sweep frequencies of a millimeter-wave radar. This indicates the frequency difference between the downward transmission and reception sweep frequencies of the millimeter-wave radar.

[0097] Optionally, if the difference between the current distance and the previous distance is less than or equal to a preset movement distance, the movement state is determined to be stationary; if the difference between the current distance and the previous distance is greater than the preset movement distance, the movement state is determined to be in motion. The preset movement distance is 0, 0.01m, or 0.02m. The previous distance refers to the distance at the user's previous moment, which is earlier than the current moment.

[0098] Figure 3 This is a schematic diagram illustrating the angle detection principle of millimeter-wave radar provided in an embodiment of this disclosure, as shown below. Figure 3 As shown, Figure (a) illustrates the situation when the user is near the left side of the millimeter-wave radar, and Figure (b) illustrates the situation when the user is near the right side of the millimeter-wave radar. Motion parameters also include the current angle, and the process of determining the current angle may include: determining the current angle based on the distance between the two receiving antennas, the transmission wavelength of the transmitting antenna, and the phase difference between the received signals from the two receiving antennas.

[0099] The phase difference between the received signals from the two receiving antennas can be determined using Formula 3 below. .

[0100] Formula 3: .

[0101] In this disclosure, the distance d2 between the two receiving antennas is relatively small, such as 6 mm. Compared to the user's current distance d1 of more than 50 cm, the included angle between the two receiving antennas is small enough that they are approximately parallel.

[0102] .

[0103] The current angle can be determined using Formula 4 below.

[0104] Formula 4: .

[0105] in, d1 represents the current angle; d2 represents the distance between the two receiving antennas; Indicates the transmission wavelength of the transmitting antenna; This indicates the phase difference between the received signals from the two receiving antennas.

[0106] When the user is near the left side of the millimeter-wave radar... When the user approaches the right side of the millimeter-wave radar, .

[0107] Optionally, if the difference between the current angle and the angle at the previous moment is less than or equal to a preset angle, the motion state is determined to be stationary; if the difference between the current angle and the angle at the previous moment is greater than the preset angle, the motion state is determined to be in motion. The preset angle is 0°, 1°, 2°, 3°, or 4°.

[0108] In some embodiments, for the above-described S13, the motion parameters further include the current distance d1 and the current angle. The current distance d1 refers to the distance from the user to the preset origin at the current moment, and the current angle. This refers to the angle between the user at the current moment and the normal perpendicular to the preset origin. See the previous embodiment d1 for details. The process of determining the value will not be repeated here.

[0109] Specifically, when the user is in motion, the current position is determined based on the current distance and current angle; the target colored light corresponding to the current position is determined based on the current position; and the target colored light is controlled to light up.

[0110] like Figure 3 As shown, the current position is (x, y). When the current angle... When greater than 90°, , At the current angle When less than 90°, , At the current angle When the angle is 90°, x = 0 and y = d1.

[0111] Based on the current location, determine the target RGB light corresponding to the current location. In one possible implementation, Figure 4 This is a schematic diagram of a colorful light strip in a display device provided in an embodiment of the present disclosure, as shown below. Figure 4 As shown, at least one of the upper frame, lower frame, left frame, and right frame of the display device 100 is provided with a light strip, which includes a plurality of colorful lights 10. Depending on the current position, a sliding window can be made on at least one of the colorful lights 10 in the light strip to determine a first target colorful light group 201 corresponding to the current sliding window 101; the colorful lights in the first target colorful light group are then used as target colorful lights.

[0112] A sliding window, or sliding window, is a standard concept in computer science (algorithms), signal processing (DSP), and data analysis. In this disclosure, "sliding a window over the colored lights in a light strip" can be understood as using a fixed-length window to move the positions (e.g., numbers) of the sequentially arranged colored lights in the light strip along a certain direction (e.g., from left to right or from right to left), thereby selecting a group of colored lights and displaying a specific effect on the newly selected group. For example, as... Figure 4As shown, taking an example where the top, bottom, left, and right borders all include LED strips, the LED strips on the top border are numbered from left to right as 1, 2, 3, ..., M-1 and M; the LED strips on the bottom border are numbered from left to right as 1, 2, 3, ..., N-1 and N; the LED strips on the left border are numbered from left to right as 1, 2, 3, ..., Q-1 and Q; and the LED strips on the right border are numbered from left to right as 1, 2, 3, ..., P-1 and P. By sliding the window in groups of 10 LEDs from left to right, multiple groups of LED strips can be identified. Specifically, the multiple groups of LED strips in the top border include LED strips numbered 1-10, LED strips numbered 2-11, ..., and LED strips numbered (M-10)-M. The lower border contains multiple groups of colored lights, including groups numbered 1-10, 2-11, ..., and (N-10)-N. Sliding windows in groups of 10 lights from right to left allows for the identification of multiple groups. Specifically, the upper border contains groups numbered M-(M-10), ..., 11-2, and 10-1. The lower border contains groups numbered N-(N-10), ..., 11-2, and 10-1. Here, the sliding window increment is one colored light. However, the sliding window increment can be reasonably set based on practical experience and application requirements; this disclosure does not impose a limitation. In addition, the number of colorful lights in a set of colorful lights is not limited. This disclosure takes 10 as an example, but in reality it can be more than 10 or less than 10.

[0113] The user's movement direction can be determined based on the current position and the previous position. For example, if the previous position is to the left of the current position, the movement direction is from left to right. Conversely, if the previous position is to the right of the current position, the movement direction is from right to left.

[0114] like Figure 4As shown, the first target colorful light group 201 corresponding to the current sliding window 101 can be determined based on the first target colorful light group corresponding to the previous sliding window 102 and the user's movement direction. Specifically, given the first target colorful light group corresponding to the previous sliding window 102, taking the user's movement from left to right as an example, based on the previous sliding window 102, the colorful lights in the upper and / or lower frame light strips are slid from left to right, for example, from colorful light groups numbered 21-30 to colorful light groups numbered 22-31, to determine the first target colorful light group corresponding to the current sliding window, thus achieving a real-time following and smooth flow effect of the colorful lights. Taking a user moving from right to left as an example, the colorful lights in the upper and / or lower frame light strips are slid from right to left, for example, from colorful light groups numbered 50-41 to colorful light groups numbered 49-40. The first target colorful light group corresponding to the current sliding window is determined, so as to achieve the effect of real-time following and smooth flow of colorful lights.

[0115] In another possible implementation, Figure 5 This is a schematic diagram of a colorful light strip in another display device provided in an embodiment of the present disclosure, as shown below. Figure 5 As shown, based on the current position A, at least one RGB light with the same or adjacent horizontal coordinate as the current position can be determined as the center RGB light. A predetermined number (e.g., 5) of RGB lights before and after the center RGB light (taking one as an example), along with the center RGB light itself, can be grouped into a first target RGB light group 201. RGB lights in the first target RGB light group 201 (e.g., 11) can be used as target RGB lights. It should be noted that if there are not enough predetermined numbers of RGB lights before or after the center RGB light, then all (less than 5) RGB lights before or after the center RGB light are used as target RGB lights. In this embodiment, by determining the center RGB light as the alignment light for the current position and expanding left and right around it, stable tracking of the light effect center is achieved while ensuring a reasonable range for the light effect.

[0116] Figure 6 This is an example of a rendering showing the effect of a colorful lighting follow-up provided in an embodiment of this disclosure, such as... Figure 6 As shown, the center of the first target RGB light group follows the user's current position (x, y) from left to right. Optionally, the brightness of the target RGB light decreases from the current position to the left and right.

[0117] While implementing lighting effects on the top and / or bottom borders, the colorful lights on the left and right borders can be fully turned on or off.

[0118] In some embodiments, the next predicted position is determined based on the current position and the current movement speed; the next second target illuminated light group is determined based on the next predicted position; and the illuminated lights in the second target illuminated light group are controlled to illuminate. As discussed above, the current movement speed is within the first preset speed range, meaning the user is in motion, and therefore, the user is highly likely to continue moving in the direction of motion in the next moment. Thus, even if the user has not yet performed their next action, the predicted second target illuminated light group can be illuminated in advance. The method of determining the second target illuminated light group based on the next predicted position is fundamentally the same as the method of determining the first target illuminated light group based on the current position; for example, see the above. Figure 4 As shown, given a first target group of colored lights at the current position, the system slides through at least one strip of lights according to the user's movement direction to predict the second target group of colored lights 202 corresponding to the next sliding window 103, for example, sliding from colored light groups numbered 22-31 to colored light groups numbered 23-32. Alternatively, see the above. Figure 5 As shown, the center RGB light is determined based on the next predicted position B to obtain the second target RGB light group 202.

[0119] In this embodiment, the next predicted position is determined based on the current position and the current movement speed. The second target colorful light group corresponding to the next predicted position is lit in advance to ensure the smooth display of the colorful effect and avoid the colorful display being fragmented due to the delay in the next position detection process.

[0120] Furthermore, the predicted position can be verified. Optionally, the user's position at the next moment can be determined and denoted as the next position; the next moment is later than the current moment corresponding to the current position. If it is confirmed that the next position is indeed the position after the current position has moved along the direction of movement, such as moving from left to right and the next position is to the right of the current position, the position prediction result of the previous stage can be determined to be accurate, and the colorful following process can continue to be executed (such as S13). If the next position is the current position, the movement state is updated to stationary, and the state of all colorful lights is updated to lit.

[0121] In some embodiments, for S13, the target RGB light is controlled to illuminate the target color.

[0122] In one possible implementation, when a user is detected in front of the display device using a sensor, the camera is activated; the camera captures an image of the user, and the user's target color is determined; the target color includes one or more combinations of the user's clothing color, accessory color, skin tone, hair color, prop color, and background color; the target color is then controlled to illuminate. For example, if there is only one target color, the target color illuminates that color. If there are multiple target colors, the target color illuminates in zones, with different zones illuminating different colors. For instance, if the user's clothing is blue, the corresponding zone of the target color illuminates could include one or more of dark blue, light blue, cyan, and green. If the user's skin is yellow, the corresponding zone of the target color illuminates could include one or more of orange, tangerine, and gold. If the user's lips are pink, the corresponding zone of the target color illuminates could include one or more of light purple-pink, cherry blossom pink, and rose red. The target RGB lighting is divided into three zones, with transitional colors used between adjacent zones. For example, the transition between "dark blue, light blue, cyan, and green" and "orange, orange-yellow, and gold" can be rendered as yellow-green or amber (such as golden orange), for example, dark blue → light blue → cyan → green → yellow-green → amber → orange-yellow → orange. The transition between "orange, orange-yellow, and gold" and "light purple-pink, cherry blossom pink, and rose red" can be rendered as red-orange and pure red, for example, orange-yellow / gold → orange → red-orange → pure red → rose red → cherry blossom pink → light purple-pink.

[0123] In another possible implementation, a user-selected color can be obtained; the target LED can be controlled to illuminate the user-selected color. The user-selected color can be a single color, such as "dark blue, light blue, cyan, and green", or a set of colors, such as "dark blue, light blue, cyan, and green".

[0124] By controlling the target colorful lights to illuminate a color pre-selected by the user, the selected color can be displayed statically or flashing. By controlling the target colorful lights to illuminate a set of colors pre-selected by the user, the colors can be dynamically rotated, flashing, or different target colorful lights can illuminate a set of colors simultaneously to achieve a colorful display effect.

[0125] In another possible implementation, the user-selected playback mode and the user-preselected color are obtained; the target LED can be controlled to illuminate the user-preselected color according to the user-selected playback mode. For example, the playback mode can include a static playback mode and a dynamic playback mode. A static playback mode refers to displaying the user-preselected color in a fixed manner. A dynamic playback mode refers to playing multiple preselected colors according to a preset playback strategy to achieve a dynamic and varied color display effect. The user-preselected color can be a single color, such as "dark blue, light blue, cyan, and green," or a group of colors, such as "dark blue, light blue, cyan, and green." The preset playback strategy can be a flowing playback strategy to achieve a flowing playback effect; or a slow gradient strategy from bright to dark to achieve a "breathing" effect; or a flashing effect; or a dynamic carousel effect, etc.

[0126] The user can choose to input manually or by voice. If voice input is selected, a microphone array is needed to collect the user's voice data.

[0127] For example, in a birthday party scene, the playback mode is selected as a flowing effect, and the color is highlighted in red.

[0128] In some embodiments, the motion state is determined to be stationary in response to the user selecting a static mode. User selection can be supported, fully considering the user's wishes. For example, if the user wants to turn off the RGB lighting effect, they can actively select a static mode, thus determining the motion state to be stationary. In the static state, all RGB lights can be turned on or off, and this can be adjusted.

[0129] Here, the user can choose to remain still by manually navigating the menu, confirming the selection of still mode in response to a triggering action on the "Still Mode" option in the menu bar. Alternatively, the user can choose to remain still by voice control, using a microphone array to collect voice data, and confirming the motion state as still in response to voice data indicating "Activate Still Mode".

[0130] Optionally, when the device is stationary, all the colorful lights in the control display device are turned on.

[0131] Optionally, the target color illuminated in a static state can be one or more combinations of the user's clothing color, accessory color, skin tone, hair color, prop color, and background color, or it can be a color pre-selected by the user. For example, if a user is detected in front of the display device using a sensor, the camera is activated; the camera captures an image of the user and determines the user's target color; the target color includes one or more combinations of the user's clothing color, skin tone, prop color, and background color; when the user is stationary in motion, all the lights in the display device are controlled to illuminate the target color. Another example is that, according to the user's selected playback mode, all the lights are controlled to illuminate the user-preselected color.

[0132] In some embodiments, regardless of whether the user in front of the screen is stationary or moving, the system can respond to user commands at any time, adjusting the brightness and / or color of the target LED light accordingly. User commands can be selections from a menu, manually entered text commands, or voice commands. Voice commands require the use of a microphone array to collect voice data; the command may request the LED light to brighten or dim, and the brightness can be adjusted at any time to suit the user's viewing experience, thereby improving the human-computer interaction experience.

[0133] In some embodiments, sensors are used to detect in real time whether a user is in front of the screen. If multiple users are present simultaneously, the user closest to the screen is used as the criterion. If the sensors do not detect a user within a preset time, it is determined that no user is present. The preset time can be set as needed, such as 15 minutes.

The DSP 1114 communicates with the system-on-a-chip 112. For example, the DSP communicates with the SOC via a serial asynchronous transceiver (UART), an integrated circuit bus (I2C), or a serial peripheral interface (SPI). Figure 10 As shown, a millimeter-wave radar with one TX and two RX channels is used. The millimeter-wave radar transmits a signal from the TX antenna, which is reflected back from the human body. The signal is then received by the RX antenna, filtered by a low-pass filter 1111, mixed by a mixer 1112, and finally output as a digital signal by an analog-to-digital converter 1113. A digital signal processor 1114 processes the digital signal and sends it to the SOC via UART, I2C, or SPI to determine motion parameters.

The colorful light driver chip 114 controls the target colorful light 10 (each LED integrates red R, green G, and blue B chips) to mix the RGB three primary colors to form the target color, thus creating a colorful effect.

[0184] In some embodiments, such as Figure 9 As shown, the display device also includes a camera 115, which is communicatively connected to the system-on-a-chip 112; for example, the camera 115 and the system-on-a-chip 112 are communicatively connected via a USB interface.
