Intelligent glasses include dimming glass, interactive glass, light-emitting glass, etc. Among them, the light-emitting glass can be configured into different colors and patterns as needed, so as to create different display effects. Generally, a light extraction structure is formed on the surface or inside of the glass, and the light incident into the glass is guided out of the glass surface through the light extraction structure to achieve light emission, or active light emission is achieved through a light-emitting element provided on the surface or inside of the glass, so as to achieve the light-emitting effect of pattern light emission.

[0038] The terms "comprising", "including" and similar terms used in the present disclosure are open-ended terms, i.e., "including / including but not limited to", indicating that other content may also be included. The term "based on" is "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment", and so on.

[0039] In the present disclosure, terms such as "first", "second", etc. are not used to limit the order and the number of components, unless otherwise specified. In the present disclosure, the meaning of "a plurality of" refers to two or more, unless otherwise specifically defined. In addition, in the present disclosure, unless otherwise specifically defined, terms such as "installed", "connected", "attached", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those skilled in the art, the specific meanings of the above terms in this text can be understood according to specific situations.

[0040] In the present disclosure, it is described by taking the glass component applied to the vehicle window glass as an example. However, it does not exclude that the glass component can be applied to environments such as doors, windows, curtain walls, aircraft glass, or ship glass. When the glass component is described as being used for the vehicle window glass, "outer" and "inner" are directions relative to the vehicle body. "Outer" refers to the direction away from the vehicle body, and "inner" refers to the direction within the space formed towards the vehicle body. It should be understood that the vehicle window glass according to the embodiments of the present disclosure includes but is not limited to the front windshield, the rear windshield, the sunroof glass, the door glass, or the corner window glass.

[0041] The light-emitting glass has a light-emitting function for realizing functions such as lighting, display, decoration, etc. Figure 1 A schematic diagram of a light-emitting glass 100 according to an embodiment of the present disclosure is shown. In Figure 1 it, the light-emitting pattern 101 on the light-emitting glass 100 can be observed from the perspective inside or outside the vehicle. In some examples, the glass of the light-emitting glass itself does not have the light-emitting property, but can extract the light of an external light-emitting element. For example, a pattern layer of a light extraction material or a light extraction structure can be formed on the surface or inside of the glass, or a light extraction structure pattern can be formed by micro-engraving inside the glass. When the external light-emitting element injects light into the glass interior, the pattern of the light extraction material or the light extraction structure exports the light to the outside of the glass through scattering or diffusion effects, presenting a light-emitting effect to form a light-emitting pattern. In some other examples, the light-emitting glass can emit light without relying on an external light source through self-luminous technology. For example, by embedding an active light-emitting element inside the glass or arranging it on the glass surface, it can directly emit light to form a light-emitting pattern.

[0042] As mentioned above, the current control methods of light-emitting glass are relatively single and lack interaction with users. Although the state of the light-emitting glass can be controlled by means such as buttons, remote controls, or software application touches. However, these methods usually require the driver to manually adjust, which has the risk of affecting driving safety. And, these methods mostly only focus on the sensory experience of the driver and rarely consider the riding experience of passengers, especially those in the back row.

[0043] The technical solution according to the present disclosure will be described in detail below based on several embodiments. First, a control method for a light-emitting glass component according to the first aspect of the present disclosure will be introduced. Specifically, Figure 2 FIG. 4 shows a flowchart of a control method 200 for a light-emitting glass component according to an embodiment of the present disclosure.

[0044] The control method 200 for a light-emitting glass component according to an embodiment of the present disclosure can be applied to the cases of passive light emission and active light emission of the light-emitting glass. In some examples, for passive light emission of the light-emitting glass, the light-emitting glass component may include a glass substrate, a light-emitting element, and a light extraction structure disposed inside or on at least one surface of the glass substrate. The light-emitting element is configured to be able to incident light into the glass substrate. The light extraction structure is configured to extract the light incident into the glass substrate by the light-emitting element from at least one surface of the glass substrate to present a light-emitting pattern. In other some examples, for active light emission of the light-emitting glass, the light-emitting glass component may include a glass substrate and a light-emitting element disposed inside or on at least one surface of the glass substrate. The light-emitting element is configured to be able to emit light actively and to be able to emit light from at least one surface of the glass substrate to present a light-emitting pattern.

[0045] As Figure 2 shown, the control method 200 for the light-emitting glass component can be specifically described as follows:

[0046] In S201, human detection information near the light-emitting glass component is received.

[0047] In some examples, for passive light emission of the light-emitting glass, the vicinity of the light-emitting glass component may refer to one side of the glass or the vicinity of the area where the pattern of the light extraction structure inside is located. The area where the pattern is located may be a planar pattern design formed by applying scattering enamel or ink on one side of the glass, or a thin film layer with a pattern pressed on the surface of the glass. Alternatively, the area where the pattern is located may also be a three-dimensional pattern design area formed by laser engraving inside or on one side of the glass. In other some examples, for active light emission of the light-emitting glass, the vicinity of the light-emitting glass component may refer to the vicinity area of the actively light-emitting light-emitting element. Here, the vicinity refers to a distance within a certain threshold from the light-emitting glass component.

[0048] The human detection information near the light-emitting glass component may refer to indicating whether a human body exists and / or there are changes in the human body. The changes in the human body may be, for example, changes in distance, movement, etc. In some examples, detecting whether a human body exists can be achieved by detecting at least one of the biological signals of the human body, such as voice, gesture, temperature, face. In other words, non-contact human detection information is used as the signal input, without the need for means such as buttons, knobs, touch, etc.

[0049] In some examples, human detection information can be collected through various identification devices or sensors to obtain human detection information at or near the light-emitting glass component. For example, by setting at least one identification device, such as a voice recognition device, a camera that captures video / images in the visible wavelength range, specific voices, specific gestures, or the faces of specific persons can be collected to detect the presence of a human. For another example, the signal of the presence of a human can be collected through a proximity sensor, such as at least one of a capacitive proximity sensor, an infrared sensor, a radar sensor, a laser sensor, an ultrasonic sensor, or a radio frequency sensor.

[0050] In S202, in response to the human detection information, the light-emitting state of the light-emitting element is changed, thereby changing the light-emitting pattern presented on at least one surface of the glass substrate.

[0051] The light-emitting element can be located on the surface, at the bottom of the glass substrate, or integrated therein. When the light-emitting glass emits light passively, when the incident light of the light-emitting element projects onto the light extraction structure, due to the change of the surface structure, the light is scattered and transmitted through the light-emitting pattern, thereby achieving the lighting effect of pattern light emission. In some examples, the light-emitting element can be a halogen lamp, a light-emitting diode (LED) lamp, or a laser lamp. The light-emitting element can be a point-like or linear light source, such as an LED strip or an LED lamp bead. When the light-emitting glass emits light actively, the light-emitting element can be an active light-emitting element, such as a transparent organic light-emitting diode (OLED) module. The transparent OLED module can be embedded inside or on the surface of the glass substrate.

[0052] The light-emitting state of the light-emitting element can be changed or maintained according to the received human detection information. For example, when the human detection information indicates that a human is detected, the light-emitting element can be turned on, so that the pattern emits light for display. Or, when the human detection signal does not change within a predetermined time threshold, the current light-emitting state of the light-emitting element is maintained, and the light-emitting pattern remains lit for display. Or when no human is detected within a certain time range, the light-emitting element can be turned off, and the pattern does not emit light for display. Or, the state of the light-emitting element, such as duration, brightness, color, etc., can be correspondingly adjusted according to the change of the human detection information, and the display state of the light-emitting pattern is correspondingly changed.

[0053] The control method 200 of the light-emitting glass component determines the light-emitting state of the light-emitting element according to the human detection information near the light-emitting glass component, without the need for the driver to manually adjust through the control interface, thus improving the driving safety. In addition, only by automatically adjusting the light-emitting state according to the human detection information near the light-emitting glass component, the interaction with passengers, especially rear passengers, can be increased.

[0054] In some embodiments, the light-emitting patterns of the light-emitting glass assembly can be uniformly controlled. For example, when the human body detection signal indicates that a human body is detected, all the light-emitting elements are turned on, and the entire light-emitting pattern is lit up simultaneously.

[0055] In some examples, human body detection information can be received at specific positions near the light-emitting pattern. For example, a sensor is provided at the middle position of the bottom of the light-emitting glass substrate. When the sensor detects that there is someone nearby, the sensor emits a human body detection signal. Also, for example, corresponding sensors are provided at the middle positions of the edges of the light-emitting glass substrate. When a certain sensor detects that there is someone nearby, this sensor emits a human body detection signal. In some other examples, corresponding sensors can be respectively provided for the positions corresponding to different light-emitting patterns, that is, multiple sensors are provided on each or some edges of the light-emitting glass substrate. In this way, when human body detection signals are received near different light-emitting patterns, the corresponding sensors will correspondingly emit human body detection signals.

[0056] In some examples, the light-emitting state of the light-emitting elements can be changed according to the human body detection information received at specific positions near the light-emitting pattern. For example, when human body detection information is received at the middle position of the bottom of the light-emitting glass, all the light-emitting elements are turned on to light up all the light-emitting patterns. Also, for example, when human body detection information is received at the middle position of a certain edge of the light-emitting glass, all the light-emitting elements are turned on to light up all the light-emitting patterns.

[0057] In some other embodiments, partial light-emitting patterns of the light-emitting glass assembly can be individually controlled. Specifically, S202 can include the following steps, see Figure 3 。 Figure 3 FIG. shows a flowchart of a control method 210 of a light-emitting glass assembly according to an embodiment of the present disclosure. As Figure 3 shown, the control method 300 of the light-emitting glass can be specifically described as follows:

[0058] In S211, according to the first relative position information between the human body and the glass substrate at the first moment, the corresponding first pattern area on the glass substrate is determined.

[0059] In some examples, the human body detection information can include the relative position information between the human body and the glass substrate. The relative position information can refer to the position information of the human body or a part of the human body relative to a certain position on the glass substrate with that position on the glass substrate as the origin. Or the relative position information can refer to the position information of the human body or a part of the human body and the position information of a certain position on the glass substrate with a certain position on the vehicle as the origin. In this way, the area of partial light-emitting patterns can be determined according to the relative position information.

[0060] Determine the corresponding first pattern area on the glass substrate according to the first relative position information of the human body and the glass substrate at the first moment T1. For example, at T1, if the position of the human body relative to a certain light extraction mechanism among multiple light extraction mechanisms on the glass substrate meets a predetermined distance requirement, then it can be determined that the pattern area on the glass substrate corresponding to this light extraction mechanism is the first pattern area. Another example is that at T1, if the position of the human body relative to a certain sub-element of the active light-emitting element on the glass substrate meets a predetermined distance requirement, then it can be determined that the pattern area on the glass substrate corresponding to this sub-element is the first pattern area.

[0061] In S212, determine the first group of light-emitting elements corresponding to the first pattern area in the light-emitting elements.

[0062] Different pattern areas can correspond to different light-emitting elements, so that separate control of different pattern areas can be achieved. According to the correspondence between the pattern area and the light-emitting element, the first group of light-emitting elements corresponding to the first pattern area can be determined.

[0063] In S213, change the light-emitting state of the first group of light-emitting elements, thereby changing the first light-emitting pattern presented in the first pattern area of the glass substrate.

[0064] The light-emitting state of a certain group of light-emitting elements can be changed according to the determined group of light-emitting elements. For example, one or more of turning on / off, light-emitting brightness, color, and duration when turned on. Since the light-emitting state of the light-emitting element changes, the state of the light-emitting pattern presented in the corresponding pattern area can be changed.

[0065] In some embodiments, the light-emitting elements or light-emitting patterns on the light-emitting glass can be grouped and controlled. For example, Figure 4 FIG. shows a flowchart of a method 300 for determining the first group of light-emitting elements according to an embodiment of the present disclosure. As Figure 4 shown, the method 300 for determining the first group of light-emitting elements can be specifically described as follows:

[0066] In S301, divide the glass substrate into multiple pattern areas.

[0067] Grouping the light-emitting patterns on the glass substrate can achieve personalized regulation of different light-emitting patterns. The pattern areas on the glass substrate can be divided into at least two groups, and each group can be independently controlled after grouping.

[0068] The patterned area on the glass substrate may refer to the area where a light extraction mechanism or an active light-emitting element presents a light-emitting pattern on at least one surface of the glass substrate. In some examples, the patterned areas can be evenly grouped. For example, the entire patterned area can be divided into multiple groups according to equal area, or grouped according to the constituent units of the patterned area. In some examples, grouping can be performed according to the complexity of the patterned area. For example, the more complex the patterned area, the finer the grouping. Specifically, the complexity of the patterned area can mean that the proportion of the pattern in the unit area is larger, or the number / types of lines of the pattern in the unit area is more.

[0069] In S302, determine the correspondence between multiple patterned areas and the light-emitting elements.

[0070] The light-emitting element can include multiple light-emitting sub-units. The correspondence between the multiple patterned areas and the light-emitting element can be set according to actual needs. For example, one or more light-emitting sub-units in the light-emitting element can control a group of patterned areas. That is, each group of patterned areas can correspond to one or more light-emitting sub-units. Each group of patterned areas after grouping can correspond one-to-one with one or more light-emitting sub-units of the light-emitting element. That is, one or more light-emitting element sub-units control the light-emitting effect corresponding to a group of patterned areas.

[0071] In some examples, for the case of evenly grouping the patterned areas, the light-emitting elements can also be evenly arranged. For example, each group of light-emitting elements includes an equal number of light-emitting sub-units, and the even arrangement of the light-emitting elements can improve the illuminance uniformity. In some examples, for the case of grouping the patterned areas according to the complexity, the number of light-emitting sub-units in each group of light-emitting elements corresponding to the more complex patterned areas can be set to be larger, so as to facilitate enhancing the level and beauty of the light-emitting pattern.

[0072] In S303, based on the correspondence, determine the first group of light-emitting elements corresponding to the first patterned area.

[0073] Determine the corresponding light-emitting elements according to the divided patterned areas and the correspondence between the patterned areas and the light-emitting elements. For the determined first patterned area, the first group of light-emitting elements corresponding to it can be determined based on the correspondence.

[0074] In some embodiments, when a human detection signal is detected at a certain set of pattern areas, the light-emitting elements of the corresponding set are turned on to light up the set of pattern areas. In this way, the corresponding grouping control of the pattern areas and the light-emitting elements can present various display effects. For example, when a person approaches each set of pattern areas in sequence, the light-emitting elements of each set are turned on in sequence to present the effect of dynamically displaying each set of pattern areas. More specifically, when the hand of a passenger sitting in the back row approaches a certain part of the pattern on the rear window, the light-emitting elements of the corresponding set are turned on because a human detection signal near that part is sensed, and thus the pattern of that part is lit up. As the position of the hand moves, the pattern areas of other sets are lit up in sequence. In this scenario, the display of the pattern on the light-emitting glass on the window is controlled by the passenger without the driver's operation. And for young passengers, this process can increase interaction and play a soothing role during a long journey or while waiting.

[0075] The above method for controlling the light-emitting state of the light-emitting elements is only an example. In the present disclosure, the means for changing the light-emitting state of the light-emitting elements is not limited to this, and can be flexibly set according to specific scenarios or requirements. Several examples are given below.

[0076] Example 1

[0077] In some embodiments, the light-emitting state of the light-emitting elements includes an on state or an off state. Changing the light-emitting state of the light-emitting elements includes changing the light-emitting state of the light-emitting elements, that is, switching between the on state and the off state of the light-emitting elements. In some examples, when the current state of the light-emitting elements is off, changing the light-emitting state of the light-emitting elements can be to turn on all the light-emitting elements; when the current state of the light-emitting elements is on, changing the light-emitting state of the light-emitting elements can be to turn off all the light-emitting elements.

[0078] In some examples, when the pattern areas and the light-emitting elements are grouped and controlled, the current state of each group of light-emitting elements is off. Changing the light-emitting state of the light-emitting elements can be to turn on a certain group of light-emitting elements. For example, when the light-emitting glass is applied to the door glass, the initial state of the light-emitting elements is off. The human detection signals at or near each set of pattern areas are collected by the human detection signal acquisition device. When the passenger's hand moves near the pattern area of group A, the light-emitting elements of the corresponding group are turned on, and the pattern area of group A is lit up. As the passenger's hand moves randomly, the pattern areas of other corresponding groups B, C, D... on the light-emitting glass are lit up in sequence.

[0079] In addition to the switching between the two modes of the on state and the off state, in some embodiments, when the current state of the light-emitting elements is the on state, changing the light-emitting state of the light-emitting elements can also be to change the on state of the light-emitting elements, where the on state includes one or more of the light-emitting brightness, light-emitting color, and light-emitting duration.

[0080] Example 2

[0081] In some embodiments, the human body detection information further includes the relative distance between the human body and the glass substrate, and the control method 210 of the light-emitting glass assembly may further include: changing the light-emitting state of the first group of light-emitting elements according to the relative distance between the human body and the glass substrate, so as to change the first light-emitting pattern presented in the first pattern area of the glass substrate.

[0082] In some examples, the initial state of the light-emitting elements of the light-emitting glass assembly is off, and the human body detection signal acquisition device acquires the human body detection signals at or near the pattern area. When the received human body detection information indicates the presence of a human body near the pattern area, the corresponding light-emitting elements light up the pattern area. After the pattern area is lit, the distance between the pattern area on the glass substrate and the human body is continuously detected. For example, at least one of a laser distance sensor, an ultrasonic distance sensor, an infrared ranging sensor, and a time-of-flight sensor can be used to calculate the distance. When the distance changes, the on-state of the light-emitting elements can be adjusted. For example, when the distance decreases, the brightness of the light-emitting elements can be increased, such as from light white to bright white; conversely, when the distance increases, the brightness of the light-emitting elements can be decreased. For another example, when the distance changes, the light-emitting mode of the light-emitting elements can be changed. For example, as the distance decreases, the light-emitting elements change from the constant-on mode to the blinking mode, or the displayed color is changed.

[0083] When the light-emitting glass assembly is applied to a car door / skylight glass, the initial state of the light-emitting elements of the light-emitting glass assembly is off, and the human body detection signal acquisition device acquires the human body detection signals at or near the pattern area. When the human body detection signals received near the A group of pattern areas indicate the presence of a human body nearby, for example, when a passenger's hand approaches the A group of pattern areas of the car door / skylight glass, the A group of pattern areas are lit. After the A group of pattern areas are lit, the distance between this group of areas and the human body is continuously detected. When the distance decreases, the brightness of the light-emitting elements increases, so that the A group of pattern areas gradually become brighter; conversely, when the distance increases, the brightness of the light-emitting elements decreases, so that the A group of pattern areas gradually become darker. For another example, when the distance decreases, the A group of pattern areas change from constant-on to blinking display, or the color system of the A group of pattern areas changes.

[0084] In the case where the initial state of the light-emitting glass is off, when a passenger's hand passes through each group of pattern areas in sequence, such as the A group of pattern areas, the B group of pattern areas..., these pattern areas can be lit in sequence for a certain time range. During this period, the distance between each group of pattern areas and the passenger's hand can be detected, and the light-emitting state of the corresponding light-emitting elements can be adjusted according to the change in the distance. In this way, the display of the pattern areas on the light-emitting glass is completely controlled by the passenger's hand. In addition, considering the change in the distance, the pattern areas can be dynamically displayed, increasing the interaction with the passenger.

[0085] Example 3

[0086] In some embodiments, the control method of the light-emitting glass assembly further includes changing different light-emitting elements according to different relative position information at different times. The control method 210 of the light-emitting glass assembly may further include the following steps: determining a corresponding second pattern area on the glass substrate according to the second relative position information of the human body and the glass substrate at the second moment T2; determining a second group of light-emitting elements corresponding to the second pattern area among the light-emitting elements; changing the light-emitting state of the second group of light-emitting elements, so as to change the second light-emitting pattern presented in the second pattern area of the glass substrate. These steps are similar to S211-S213, so they will not be described in detail.

[0087] In some embodiments, the method 210 further includes obtaining the time intervals of the human body detection signals at different pattern areas, and determining the light-emitting states of different light-emitting elements according to the time intervals. For example, the method 210 further includes the following steps:

[0088] In S2111, determine the time interval between the second moment T2 and the first moment T1.

[0089] In S2112, according to the time interval, change the light-emitting states of the first group of light-emitting elements and / or the second group of light-emitting elements, so as to change the first light-emitting pattern presented in the first pattern area of the glass substrate and / or the second light-emitting pattern presented in the second pattern area.

[0090] In some examples, the initial state of the light-emitting elements of the light-emitting glass assembly is off, and the human body detection signal collects the human body detection signals at or near different pattern areas. When the received human body detection signal indicates that there is a human body near a certain pattern area, that pattern area is lit. After that pattern area is lit, continuously detect the human body detection signals at or near other pattern areas. When human body detection signals are detected at adjacent pattern areas and are lit in sequence, obtain the time intervals of the human body detection signals at different pattern areas. In some examples, the time interval can be obtained by a timer. The light-emitting states of different light-emitting elements can be adjusted according to the obtained time intervals. For example, when the time interval is greater than the first interval threshold, the on-time of the light-emitting elements can be increased, such as from 1 s to 2 s or 5 s; conversely, when the time interval is less than or equal to the second interval threshold, the on-time of the light-emitting elements can be decreased, for example, the on-time is 0.5 s. For another example, when the time interval is greater than the first interval threshold, the light-emitting mode of the light-emitting elements can be set to monochromatic; when the time interval is less than or equal to the second interval threshold, the light-emitting mode of the light-emitting elements can be set to color. Here, the first interval threshold is greater than the second interval threshold.

[0091] When the light-emitting glass is applied to the door / sunroof glass, the light-emitting elements of the light-emitting glass assembly are in the initial state of being off, and the human body detection signal acquisition unit acquires the human body detection signals at or near different pattern regions. When the human body detection signals received near the pattern regions of Group A indicate the presence of a human body nearby, for example, when a passenger's hand approaches the pattern regions of Group A of the door / sunroof glass, the pattern regions of Group A are lit up. After the pattern regions of Group A are lit up, the human body detection signals of other groups of pattern regions are continuously detected. When human body detection signals are detected at the pattern regions of adjacent groups B, C, and D and are lit up in sequence, the time intervals of the human body detection signals at different groups of pattern regions are obtained. When the time interval is greater than the first interval threshold (for example, 1 s), the turn-on time of the light-emitting elements of the corresponding group can be set to 2 s; conversely, when the time interval is less than or equal to the second interval threshold (for example, 100 ms), the turn-on time of the light-emitting elements of the corresponding group can be set to 0.5 s. For another example, when the time interval is greater than the first interval threshold, the light-emitting mode of the light-emitting elements can be set to monochromatic (such as orange or blue); when the time interval is less than or equal to the second interval threshold, the light-emitting mode of the light-emitting elements can be set to color.

[0092] In the case where the light-emitting glass is in the initial state of being off, when a passenger's hand passes through each group of pattern regions in sequence, for example, the pattern regions of Group A, the pattern regions of Group B... these pattern regions can be lit up in sequence for a certain time range. During this period, the time intervals when different groups of pattern regions are lit up can be detected, and the light-emitting states of the corresponding light-emitting elements can be adjusted according to the changes in the time intervals. Such processing takes into account that when the rear passengers are children, the hand control actions are relatively repetitive or simple. Setting the light-emitting states of the light-emitting elements according to the time intervals can increase the complexity and interaction of the display, which is beneficial in the case of long waiting times.

[0093] Example 4

[0094] In some embodiments, the human body detection information further includes the gesture information or action information of the human body. The method for controlling the light-emitting glass assembly to change the light-emitting state of the light-emitting elements in response to the human body detection information further includes: changing the light-emitting state of the first group of light-emitting elements according to the gesture information or action information, so as to change the first light-emitting pattern presented in the first pattern region of the glass substrate.

[0095] In some examples, the initial state of the light-emitting elements of the light-emitting glass assembly is off, and a human detection signal acquisition device is used to acquire the human detection signal at or near the pattern area. When the human detection information indicates that there is a human presence near the pattern area, the corresponding light-emitting elements light up the part or all of the pattern area. After the pattern area is lit up, gestures or movements near the pattern area are detected. For example, a gesture recognition sensor can be used to acquire gesture movements. When the acquired gesture movements meet the requirements, the light-emitting state of the light-emitting elements is adjusted accordingly. In some other examples, movement information of the face or human body posture can also be acquired, and when the movement information meets the predetermined conditions, the light-emitting state of the light-emitting elements is adjusted accordingly.

[0096] For example, when the light-emitting glass is applied to a skylight glass, the initial state of the light-emitting elements of the light-emitting glass assembly is off, and a human detection signal acquisition device such as an infrared sensor acquires the human infrared signal at or near the pattern area. When someone is detected at or near the first pattern area of the pattern area, the first pattern area is lit up. The gesture recognition sensor captures and acquires the gesture movements. If the acquired gesture movements meet the recognition requirements, the light-emitting elements can be adjusted to the corresponding light-emitting states, such as brightness adjustment, color switching, breathing frequency control, etc. Another example is that when someone is detected at or near the first pattern area of the pattern area, the gesture recognition sensor starts to work to capture and acquire the gesture movements. If the acquired gesture movements meet the recognition requirements, the first light-emitting element can be adjusted to the corresponding light-emitting states, such as on / off, brightness adjustment, color switching, breathing frequency control, etc.

[0097] In addition to being implemented in the form of software control methods, the above technical solutions can also be implemented, for example, through corresponding hardware circuits. In other words, the control method of the above light-emitting glass can be implemented by software stored in a computer-readable storage medium in combination with corresponding hardware components. The computer-readable storage medium stores computer-readable program instructions for executing various embodiments of the present disclosure. A computer-readable storage medium can be a tangible device that can hold and store instructions used by an instruction execution device. A computer-readable storage medium can be, for example, but not limited to, an electrical storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the above. More specific examples (non-exhaustive) of the computer-readable storage medium include: a portable computer disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disc (DVD), a memory stick, a floppy disk, a mechanical encoding device, such as a punched card or raised structures in grooves storing instructions thereon, and any suitable combination of the above. The computer-readable storage medium used herein is not construed as an instantaneous signal itself, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission medium (e.g., optical pulses through an optical fiber cable), or electrical signals transmitted through wires.

[0098] In addition, the present disclosure also relates to a control unit for a light-emitting glass assembly. Figure 5 A schematic diagram of a control unit 400 according to an embodiment of the present disclosure is shown. As Figure 5 shown, the schematic diagram of the control unit 400 includes a processor 410 and a memory 420 coupled thereto. The processor 410 is, for example, a central processing unit (CPU). Computer-readable instructions are stored in the memory 420, and when the computer-readable instructions are executed by the processor 410, the processor 410 is caused to implement the control method of the light-emitting glass assembly according to the first aspect of the present disclosure. The processor 410 and the memory 420 are connected to each other through a bus, and an input / output (I / O) interface is also connected to the bus. Additionally, the control unit 400 may further include: an output unit, and the output unit may include an autonomous display function layer and / or a light source. In some examples, the autonomous display function layer may be, for example, a flexible OLED display, which can be sandwiched into or attached to the surfaces of the front windshield glass, side window glass, and rear windshield glass.

[0099] In addition, the control unit 400 can further include a plurality of components connected to the I / O interface ( Figure 5(not shown in the figure), including but not limited to: the in-vehicle interaction interface of the central control screen, sensors, in-vehicle clocks, timers communicatively connected to the vehicle, electronic devices communicating with the vehicle, keyboards, mice, etc.; an output unit, for example, the output unit may include an autonomous display function layer and / or light sources, as well as various types of displays, speakers, etc.; a storage unit, for example, magnetic disks, optical discs, etc.; and a communication unit, for example, network cards, modems, wireless communication transceivers, etc. The communication unit allows the control unit 400 to exchange information / data with other devices through a computer network such as the Internet and / or various telecommunication networks.

[0100] At this time, the computer-executable instructions stored in the memory 420, when executed, cause the processor 410 to execute the Figures 2 to 4 control method of the light-emitting glass assembly according to any one of the various embodiments shown.

[0101] In some embodiments, the control unit may be an independent hardware and software combined module, or any suitable hardware module. In some examples, when applied to vehicle glass, the control unit may be integrated with the vehicle control unit. The vehicle control unit may be any control unit including the vehicle side, for example, an in-vehicle electronic control unit (ECU) including a central control unit, an in-vehicle entertainment system, a body control unit, etc.

[0102] In some embodiments, the control unit is configured to communicate with a sensor unit and / or a switch device, etc., so that the control unit can provide illumination in response to signals or instructions of the sensor unit and / or the switch device, and the communication protocol includes but is not limited to LIN, CAN, Melibus, ISELED or other types of transmission buses.

[0103] Figure 6 A schematic diagram of a light-emitting glass assembly 600 according to an embodiment of the present disclosure is shown. The light-emitting glass assembly 600 includes a glass substrate 601, a light extraction mechanism 602, a light-emitting element 603, and a control unit (not shown in the figure). The glass substrate 601 includes at least one surface. The light-emitting element 603 is configured to be able to incident light into the glass substrate. The light extraction structure 602 is disposed inside or on at least one surface of the glass substrate, and the light extraction structure is configured to be able to extract the light incident into the glass substrate from at least one surface of the glass substrate to present a light-emitting pattern. The light-emitting glass assembly 600 may further include at least one sensor unit 604, and the at least one sensor unit is configured to be able to provide the human body detection information. The at least one sensor unit 604 may be one or more of a proximity sensor, a distance sensor, and a gesture motion sensor.

[0104] Figure 6As shown, when the hand of a passenger moves near the first group of pattern areas, the light-emitting elements in the corresponding group are turned on, and the pattern areas in this group are illuminated. The light-emitting elements 603 are installed at the bottom of the glass substrate, and the sensor unit 604 is installed in the non-window area of the vehicle door. From the perspective of the passenger, the light-emitting elements 603 and the sensor unit 604 are not visible.

[0105] In some embodiments, the glass substrate 601 has a single-layer structure, and the light extraction mechanism 602 is provided on the surface of the glass substrate. In some examples, the light extraction mechanism can be a planar pattern formed by printing a film layer, enamel, ink, or other scattering particles on the surface of the glass substrate. In some other examples, the light extraction mechanism can be a three-dimensional pattern formed by laser engraving on the surface of the glass substrate.

[0106] In some embodiments, the glass substrate 601 is a double-layer glass plate, and the light extraction mechanism is provided on the outer surface of the glass plate or sandwiched between the two layers of glass plates.

[0107] In some embodiments, the light-emitting elements 603 are arranged at the edge of the glass substrate. For example, the light-emitting elements can be LED strip lights or LED lamp beads. The light-emitting elements 603 can be configured to incident light into the glass substrate. Compared with the case where the light-emitting elements are arranged on the surface of the glass substrate, the LED lights can be arranged at the bottom edge of the glass substrate, such as in the thickness direction. Therefore, the light-emitting glass assembly is more suitable for the vehicle door glass in a lifting and friction environment, and thus its service life can be improved. In addition, placing the light-emitting elements on the surface of the glass substrate rather than in the glass body can reduce the process cost and is more suitable for a wide range of applications.

[0108] In some embodiments, the light-emitting elements 603 can include a light source and a light guiding element. The incident light emitted by the light source is emitted through the light guiding element, enters the glass substrate, and undergoes total internal reflection within the glass substrate. The light guiding element is beneficial for reducing light loss and improving the light-emitting visual effect. The light source, the light guiding element, and the glass substrate can be installed with each other by means of bonding or mechanical connection, etc.

[0109] In some examples, the light-emitting elements 603 are one or more of monochromatic lamp beads, three-color RGB lamp beads, or four-color RGBW lamp beads. The three-color RGB lamp beads include three primary colors: red, green, and blue. These three colors can be mixed together in different brightness ratios to form a variety of colors. The RGBW four-color lamp beads are composed of four colors: red, green, blue, and white. By controlling the mixing ratio of these four colors, various different lighting effects can be created, including white light, colored light, and warm-colored light, etc. Compared with monochromatic LED lamp beads, the multi-color lamp beads include multiple LED chips, and the color can be precisely adjusted by controlling the brightness of each LED chip.

[0110] In some examples, the brightness can be adjusted by directly regulating the current of each LED chip. In other examples, the brightness and color of the LED can be adjusted by using PWM (Pulse Width Modulation) waves. The current output by the PWM wave is constant, and the percentage (duty cycle) of the time for which the output current is regulated by the high-frequency switching of the switch output in the total time is adjusted. The high-frequency switching of the switch output in PWM makes the human eye unable to recognize the switching of the LED lamp, and only the change in the overall brightness can be seen. The larger the duty cycle, the greater the brightness of the LED emission. Since this relationship is a linear relationship, it is easier to precisely regulate the LED by using the PWM method. As for the color switching, the color order of the PWM wave can be set to the corresponding value of the next color, which can meet the requirements of different colors.

[0111] Figure 7 FIG. shows a schematic diagram of a light-emitting glass assembly 610 according to an embodiment of the present disclosure. The light-emitting glass assembly 610 includes a glass substrate 611, a light-emitting element 612, and a control unit (not shown in the figure). The glass substrate 611 includes at least one surface. The light-emitting element 612 is disposed inside or on at least one surface of the glass substrate 611. The light-emitting element 612 is an active light-emitting element, for example, an OLED module. The light-emitting element 612 can cause light to exit from at least one surface of the glass substrate 611 to present a light-emitting pattern. Figure 7 The dashed lines in show the grouping of the light-emitting patterns on the glass substrate.

[0112] In some examples, the light-emitting glass assembly 610 includes at least one sensor unit 614, and the light-emitting state of the OLED module can be controlled by receiving a human body detection signal through the sensor unit. In other examples, the OLED module can also be adjusted by touch.

[0113] In Figures 6 - 7 example, the light-emitting patterns on the light-emitting glass assembly are uniformly controlled. For example, when the human body detection signal indicates that a human body is detected, all the light-emitting elements are turned on, and the entire light-emitting pattern is lit up simultaneously. In some embodiments, the pattern regions and the light-emitting elements can be grouped and controlled, that is, the pattern regions and the light-emitting elements respectively include multiple groups, and each group of patterns corresponds to each group of light-emitting elements one by one, and the light-emitting elements are configured to light up the corresponding each group of light-emitting patterns.

[0114] Specifically, in some examples, the pattern regions can be evenly grouped. For example, the entire pattern region can be divided into multiple groups according to equal area, or grouped according to the constituent units of the pattern region. For example, for a strip-shaped pattern region, it can be equally divided into multiple sub-pattern regions of the same length. In some examples, grouping can also be performed according to the complexity of the pattern region. For example, the more complex the pattern region, the finer the grouping. Specifically, the complexity of the pattern region can refer to a higher proportion of the pattern within a unit area, or a larger number / types of lines of the pattern within a unit area.

[0115] Correspondingly, for the case of evenly grouping the pattern regions, the light-emitting elements can also be evenly arranged. For example, for a strip-shaped pattern region, the light-emitting elements can be linearly arranged, and each group of light-emitting elements can include an equal number of light-emitting sub-units, such as LED lamp beads. For the case of grouping the pattern regions according to complexity, the number of light-emitting sub-units in each group of light-emitting elements corresponding to the more complex pattern regions can be set to be larger, that is, the light-emitting elements in the more complex pattern regions are denser.

[0116] In some embodiments, the sensor unit can be disposed at the four peripheral edges of the light-emitting glass. In some examples, when the light-emitting glass assembly is applied to a car door glass / sunroof, the sensor unit can be disposed within the window frames around the car door glass, and the sensor unit is not visible from the outside of the window frame. The sensor unit collects human detection signals at the glass, especially at the pattern regions. In the scenario where the light-emitting glass assembly is applied to a car door glass, when a person's hand approaches, a part of the hand will approach the pattern region on the glass substrate, and another part of the hand will approach the sensor unit located within the window frame, such as the sensor unit inside the car door frame. Thus, the sensor unit can collect human detection signals at or near the glass substrate.

[0117] In some examples, the sensor unit can include multiple groups of sensor sub-units, and each group of sensor sub-units is configured to receive nearby human detection signals. The multiple groups of sensor sub-units correspond to the multiple groups of pattern regions, and their positions are as close as possible. Each group of sensor sub-units collects human detection signals at the corresponding group of pattern regions.

[0118] In some embodiments, the light-emitting glass assemblies 600, 610 can further include a timing unit. The timing unit is configured to calculate the signal time intervals between different groups of sensor sub-units. The control unit can adjust the light-emitting states of each group of light-emitting elements according to the time intervals counted by the timing unit.

[0119] In some embodiments, the sensor unit includes a proximity sensor for detecting the presence of a human body to be measured without contacting the object to be measured. The proximity sensor can be any one of a capacitive proximity sensor, an infrared sensor, a radar sensor, a laser sensor, or an ultrasonic sensor.

[0120] In some examples, the proximity sensor is an infrared sensor that detects the human body through infrared technology. The infrared sensor has an infrared emitter and a receiver built in. The emitter is used to continuously emit infrared rays in all directions and convert the infrared rays that bounce back into electrical signals when received. Since the human body temperature is usually higher than the surrounding ambient temperature, the human body emits infrared rays in the air. When someone approaches, the infrared signal received by the infrared sensor will be higher than the surrounding environment, so the presence or absence of a human body can be determined accordingly. The infrared sensor has good stability and a high response speed and can detect and feedback the detection result within the millisecond level.

[0121] In some examples, the proximity sensor is a laser sensor. The detection distance can be set. When an occlusion of the laser sensor is detected within the detection distance, it can be considered that a human body is detected.

[0122] The sensor unit can output high and low level signals to the control unit according to the detected human body detection signal. For example, when a human body is detected, the sensor unit sends a high level signal to the control unit, and the control unit outputs a high level signal to control the switch of the light-emitting element.

[0123] In some embodiments, in addition to the proximity sensor, the sensor unit may further include a distance sensor. When the human body detection signal collected by the proximity sensor indicates that there is a human body near the light-emitting glass, the pattern area is lit. After the pattern area is lit, the distance sensor is used to continuously detect the distance from the human body. The distance sensor can be at least one of a laser distance sensor, an ultrasonic distance sensor, an infrared ranging sensor, and a time-of-flight sensor. The distance sensor transmits the collected distance to the control unit to adjust the on state of the light-emitting element.

[0124] In some embodiments, the sensor unit may further include a gesture sensor. When the human body detection signal collected by the proximity sensor or the gesture sensor indicates that there is a human body near the light-emitting glass, the pattern area is lit. After the pattern area is lit, the gesture sensor is used to continuously detect the gesture actions near the pattern area. When the gesture actions meet the predetermined requirements, the gesture sensor transmits the signal that the collected gesture actions meet the requirements to the control unit to adjust the on state of the light-emitting element.

[0125] The present disclosure also relates to a vehicle that includes a control unit of a light-emitting glass according to any one of the embodiments of the present disclosure or a light-emitting glass assembly according to any one of the embodiments of the present disclosure.

[0126] The present disclosure also provides a computer program product, which is tangibly stored on a computer-readable storage medium and includes computer-executable instructions that, when executed, cause at least one processor to execute the control method of the light-emitting glass assembly in various embodiments of the present disclosure.

[0127] Generally, the various example embodiments of the present disclosure may be implemented in hardware or a dedicated circuit, software, firmware, logic, or any combination thereof. Some aspects may be implemented in hardware, while other aspects may be implemented in firmware or software that can be executed by a controller, a microprocessor, or other computing devices.

It should be understood that the light-emitting control device 700 can be implemented to implement Figures 2 to 4 the functions of the control methods 200, 210, or 300 of the light-emitting glass assembly of any one of Figure 8 As can be seen from

[0130] A plurality of components in the light-emitting control device 700 are connected to the I / O interface 705, including: an input unit 706, such as a keyboard, a mouse, etc.; an output unit 707, such as various types of displays, speakers, etc.; a storage unit 708, such as a magnetic disk, an optical disc, etc.; and a communication unit 709, such as a network card, a modem, a wireless communication transceiver, etc. The communication unit 709 allows the light-emitting control device 700 to exchange information / data with other devices through a computer network such as the Internet and / or various telecommunication networks.

[0131] The various methods described above, such as the control method of the light-emitting glass assembly, can be executed by the processing unit 701. For example, in some embodiments, the control method of the light-emitting glass assembly can be implemented as a computer software program, which is tangibly contained in a machine-readable medium, such as the storage unit 708. In some embodiments, part or all of the computer program can be loaded and / or installed onto the light-emitting control device 700 via the ROM 702 and / or the communication unit 709. When the computer program is loaded into the RAM 703 and executed by the CPU 701, one or more actions or steps of the methods described above can be executed.

[0132] In summary, among the technical solutions according to the present disclosure, according to the control method of the light-emitting glass assembly of the present disclosure, the light-emitting control unit will determine the light-emitting state of the light-emitting element according to the human detection signal at the glass substrate, which can improve the driving safety and increase the interaction with passengers.

[0133] Although the various example embodiments of the present disclosure can be implemented in hardware or dedicated circuits as described above, the above-described control device can be implemented either in the form of hardware or in the form of software because: in the 1990s, it was easy to determine whether a technological improvement belonged to an improvement in hardware (e.g., an improvement in circuit structures such as diodes, transistors, switches, etc.) or an improvement in software (e.g., an improvement in method flows). However, with the continuous development of technology, many method flow improvements today can almost all be achieved by programming the improved method flow into a hardware circuit. In other words, by programming different programs for the hardware circuit, the corresponding hardware circuit structure is obtained, that is, the change of the hardware circuit structure is realized. Therefore, it cannot be said that an improvement in a method flow cannot be implemented with a hardware entity module. For example, a Programmable Logic Device (PLD) (e.g., a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by a user's programming of the device. A designer can program by himself to "integrate" a digital system on a programmable logic device, without having to ask a chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing. The original code before compilation also has to be written in a specific programming language, which is called a Hardware Description Language (HDL), and there is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. Currently, the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog.Those skilled in the art should also be clear that only by slightly logically programming the method flow with the above-mentioned several hardware description languages and programming it into an integrated circuit can a hardware circuit for implementing the logic method flow be easily obtained.

[0134] The computer-readable program instructions or computer program products for executing the various embodiments of the present disclosure can also be stored in the cloud. When needed, users can access the computer-readable program instructions stored in the cloud for executing an embodiment of the present disclosure through the mobile Internet, fixed network or other networks, so as to implement the technical solutions disclosed in the various embodiments of the present disclosure.

[0135] The above are only optional embodiments of the present disclosure and are not used to limit the embodiments of the present disclosure. For those skilled in the art, the embodiments of the present disclosure can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the embodiments of the present disclosure shall be included in the protection scope of the embodiments of the present disclosure.

[0136] Although the embodiments of the present disclosure have been described with reference to several specific embodiments, it should be understood that the embodiments of the present disclosure are not limited to the specific embodiments disclosed. The embodiments of the present disclosure are intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. The scope of the claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
