In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a light-emitting fabric provided in the present invention.
The luminous fabric comprises M first direction luminous yarns 11, M second direction luminous yarns 12, M first controllable switch modules 13, M second controllable switch modules 14 and M latch modules 15, wherein the M first controllable switch modules 13 are all connected with a first end of a power supply, the M second controllable switch modules 14 are all connected with a second end of the power supply, and M is not less than 1 and is an integer;
the ith first direction light-emitting yarn 11 is connected with the control module 16 through the ith first controllable switch module 13, at least one second direction light-emitting yarn 12 is lapped on the ith first direction light-emitting yarn 11, two ends of each second direction light-emitting yarn 12 bypass the lapped ith first direction light-emitting yarn 11 and then are connected with the ith latch module 15 through the ith second controllable switch module 14, wherein i is more than or equal to 1 and less than or equal to M, and i is an integer;
the control module 16 is configured to determine a working sequence of each latch module 15 according to the content to be displayed on the received light-emitting fabric, sequentially output a control signal corresponding to the content to the currently-operating latch module 15 according to the working sequence, control the on-off states of the first controllable switch module 13 and the second controllable switch module 14 corresponding to the currently-operating latch module 15 through the control signal, so that the first directional light-emitting yarn 11 corresponding to the currently-operating latch module 15 and each second directional light-emitting yarn 12 corresponding to the content on the first directional light-emitting yarn 11 form a loop, and control the currently-operating latch module 15 to latch the control signal before sending the control signal to the next latch module 15 so as to keep the loop on.
In this embodiment, it is considered that the driving circuit in the prior art mainly uses a time division multiplexing principle when the light-emitting fabric emits light, and realizes the display of the content to be displayed by relying on the visual retention effect of human eyes. However, in this way, the brightness of the fabric to be lighted decreases as the number of matrix rows and columns of the fabric increases, which affects the user experience. In order to solve the technical problem, the invention provides a light-emitting fabric, which establishes a signal latch mechanism from two aspects of a weaving mode and control logic, thereby ensuring that the light-emitting fabric of the part which emits light can emit light all the time.
The light-emitting fabric comprises M first direction light-emitting yarns 11, M second direction light-emitting yarns 12, M first controllable switch modules 13, M second controllable switch modules 14 and M latch modules 15, it is first to be noted that at least one second direction light-emitting yarn 12 may be lapped on the ith first direction light-emitting yarn 11, and in consideration of the needs of some application scenarios, at least one second direction light-emitting yarn 12 may be lapped on all the first direction light-emitting yarns 11 to form at least one light-emitting pixel, so as to meet the display requirements of the light-emitting fabric. It should be understood that, in the present application, the knitting manner adopted by each of the first direction luminescent yarn 11 and the second direction luminescent yarn 12 in the luminescent fabric is a biaxial yarn feeding structure textile structure of a terry shaft in terms of textile structure, and the knitting of the textile structure can be realized by a jacquard process, a yarn filling process, an electric embroidery process, a napping process, a floating process, and the like, which are not particularly limited herein.
The control module 16 may determine an operation sequence of each latch module 15 according to the content to be displayed of the received light-emitting fabric, sequentially output a control signal corresponding to the content to the currently operating latch module 15 according to the operation sequence, control the on-off states of the first controllable switch module 13 and the second controllable switch module 14 corresponding to the currently operating latch module 15 through the control signal, so as to enable the first luminescent yarn 11 corresponding to the currently operating latch module 15 and each second luminescent yarn 12 corresponding to the content on the first luminescent yarn 11 to form a loop, and control the currently operating latch module 15 to latch the control signal before sending the control signal to the next latch module 15, so as to keep the loop conductive, where, as shown in fig. 1, the loop may be specifically a loop formed by a second end of the power supply, the second controllable switch module 14, the first luminescent yarn 12, the first luminescent yarn 11, the first controllable switch module 13, and a first end of the power supply. It can be seen that, the light-emitting fabric is split into the light-emitting blocks corresponding to the latch modules 15, so that the light-emitting fabric is kept on being turned off after emitting light, and it can be understood that when the content to be displayed of the light-emitting fabric changes, only the new working sequence of each latch module 15 needs to be determined again according to the control logic in the present application, and corresponding control actions are performed.
It should be noted that the control module 16 herein may specifically include a control chip, and if the control chip itself does not have a communication function, the control module 16 may further include a communication module connected to the control chip. The control chip includes, but is not limited to, a MCU or an ARM processor or an embedded processor or a DSP chip or an FPGA chip, etc. which have IO output functions. And if the IO port of the control chip for implementing connection is not enough to be used, the control module 16 may further include an IO expansion chip to meet the control requirement in the present application, which is not particularly limited herein and is determined according to the actual requirement.
In addition, specifically, when the first luminescent yarn 11 is a transverse luminescent yarn, the second luminescent yarn 12 is a longitudinal luminescent yarn; when the first luminescent yarn 11 is a md luminescent yarn, the second luminescent yarn 12 is a cd luminescent yarn. The voltage output by the power supply needs to meet the power supply requirements of each first direction light-emitting yarn 11 and each second direction light-emitting yarn 12, for example, the voltage output by the power supply can be 80-280V of high-voltage alternating current.
In summary, the present application provides a light-emitting fabric, which changes the knitting manner of the second direction light-emitting yarn 12 to form light-emitting pixels in the knitting manner; viewed from the control logic, through the control logic of the control module 16, the first directional luminous yarn 11 corresponding to the currently operating latch module 15 and each second directional luminous yarn 12 corresponding to the content on the first directional luminous yarn 11 form a loop, and the currently operating latch module 15 is controlled to latch the control signal to keep the loop conductive before sending the control signal to the next latch module 15. It is thus clear that, compare in prior art, this application has guaranteed through establishing above-mentioned signal latch mechanism that luminous fabric of luminous part can give out light all the time to make luminous luminance of luminous fabric not influenced by its matrix row and column number, promoted user's use and experienced.
On the basis of the above-described embodiment:
as a preferred embodiment, the light emitting fabric further comprises insulating yarns;
each first direction luminous yarn 11 and each insulating yarn are woven according to a cross-woven plain weave structure, a corresponding second direction luminous yarn 12 is respectively lapped on each first direction luminous yarn 11 between two adjacent insulating yarns, and two ends of each second direction luminous yarn 12 are connected with an ith latch module 15 through an ith second controllable switch module 14 after bypassing the lapped ith first direction luminous yarn 11.
In the present embodiment, the inventor further considers the support reliability and the practicability of the light-emitting fabric, and the light-emitting fabric may further include insulating yarns, where the specific number of the insulating yarns and the thickness of each insulating yarn are not particularly limited.
Specifically, referring to fig. 2 and fig. 3, fig. 2 is a schematic diagram of a knitting structure of a light-emitting fabric provided in the present invention; fig. 3 is a schematic diagram of a weaving structure of another light-emitting fabric provided by the invention. As shown in fig. 2, the number of the insulating yarns is 3, the number of the transverse luminescent yarns is 4, and the number of the longitudinal luminescent yarns is 4 × 4=16, where the second luminescent yarns 12 are lapped on the corresponding transverse luminescent yarns; as shown in fig. 3, the first direction-emitting yarns 11 are the transverse direction-emitting yarns, and the second direction-emitting yarns 12 are the longitudinal direction-emitting yarns, and the physical overlapping manner of overlapping the second direction-emitting yarns 12 with the corresponding first direction-emitting yarns 11 is shown.
In a preferred embodiment, both ends of each second directional luminous yarn 12 lapped on the ith first directional luminous yarn 11 bypass the lapped ith first directional luminous yarn 11 and are connected with the ith latch module 15 through the ith second controllable switch module 14.
In this embodiment, the inventor further considers the reliability of each second direction light-emitting yarn 12 overlapping the corresponding first direction light-emitting yarn 11, so that both ends of each second direction light-emitting yarn 12 overlapping the ith first direction light-emitting yarn 11 bypass the ith first direction light-emitting yarn 11 overlapping the ith first direction light-emitting yarn and are connected, and thus the connected ends are connected with the ith latch module 15 through the ith second controllable switch module 14 to form a light-emitting pixel point and further ensure the support reliability of the light-emitting fabric.
Here, the length of the connection line drawn after each second luminescent yarn 12 bypasses the i-th first luminescent yarn 11 overlapped with the second luminescent yarn and is connected is not particularly limited.
Specifically, referring to fig. 4 and 5, fig. 4 is a schematic view of a weaving structure of a light emitting fabric in the prior art, and fig. 5 is a schematic view of a weaving structure of another light emitting fabric provided in the present invention. Wherein, as shown in fig. 4, the figure shows a side cross-sectional view of the prior art light-emitting fabric woven by a cross-woven plain weave structure, only considering the case that the light-emitting fabric only includes two light-emitting yarns, namely a transverse light-emitting yarn and a longitudinal light-emitting yarn. Fig. 5 shows a schematic diagram of knitting the transverse luminescent yarn as the first direction luminescent yarn 11 and the longitudinal luminescent yarn as the second direction luminescent yarn 12, and then overlapping the longitudinal luminescent yarn on the corresponding transverse luminescent yarn and bypassing the overlapped transverse luminescent yarn at two ends and connecting the transverse luminescent yarns according to the present application, which can be specifically shown in fig. 5.
As a preferred embodiment, N second luminescent yarns 12 are overlapped on each first luminescent yarn 11, wherein N × M = the total number of the second luminescent yarns 12, N ≧ 1 and N is an integer;
the ith second controllable switch module 14 includes N first controllable switches;
the first ends of the N first controllable switches are connected to the second end of the power supply, the second ends of the N first controllable switches are connected to the N second directional light-emitting yarns 12 lapped on the ith first directional light-emitting yarn 11 in a one-to-one correspondence manner, and the control ends of the N first controllable switches are connected to the ith latch module 15.
In this embodiment, each first direction-emitting yarn 11 may be lapped with N second direction-emitting yarns 12, the ith second controllable switch module 14 includes N first controllable switches, and thus, controlling the on-off state of the ith second controllable switch module 14 is controlling the on-off state of each first controllable switch in the ith second controllable switch module 14.
It can be seen that the control logic for each second controllable switch module 14 can be simply and reliably implemented by the above arrangement, which is convenient to implement.
As a preferred embodiment, the first controllable switch is a first optocoupler;

The first direct-current power supply may be a battery, and is not particularly limited herein, and may satisfy the execution logic requirement of the first optocoupler.
Of course, the first controllable switch may also be another controllable switch device capable of meeting the device voltage withstand standard (such as high-voltage alternating current), and is not particularly limited herein.
As a preferred embodiment, when the power source is a second dc power source, the light-emitting textile further comprises a voltage conversion module;
the input end of the voltage conversion module is connected with the second direct-current power supply, the first output end of the voltage conversion module is connected with the M first controllable switch modules 13, and the second output end of the voltage conversion module is connected with the M second controllable switch modules 14 and used for converting the direct-current voltage output by the second direct-current power supply into alternating-current voltage.
In this embodiment, the inventor further considers that the voltage output by the power supply needs to satisfy the power supply requirements of each first direction light-emitting yarn 11 and each second direction light-emitting yarn 12, and it can be understood that each first direction light-emitting yarn 11 and each second direction light-emitting yarn 12 need to be supplied with a high-voltage alternating current to achieve light emission. Therefore, when the power source is the second dc power source, the power requirement for each of the first directional luminescent yarns 11 and each of the second directional luminescent yarns 12 cannot be satisfied, and the light-emitting textile may further include a voltage conversion module to convert the dc voltage output by the second dc power source into an ac voltage.
Specifically, the second dc power source includes, but is not limited to, a battery, and the voltage conversion module converts the low-voltage dc voltage output by the second dc power source into a high-voltage ac voltage corresponding to the power supply requirement, such as a high-voltage ac of 80-280V, according to the power supply requirement, which is not limited herein.
It can be seen that, the arrangement of the voltage conversion device can ensure that the power supply requirements for each first direction luminous yarn 11 and each second direction luminous yarn 12 are met, so as to ensure that each first direction luminous yarn 11 and each second direction luminous yarn 12 can be reliably powered and emit light when needed.
