Problems solved by technology

[0005] (1) If the method of bonding the sensing layer and the screen layer with glue is adopted, the screen will wrinkle during the process of winding and lowering the screen, resulting in poor projected picture effect;
[0006] (2) If the induction layer is separated from the curtain layer, as described in the interactive projection screen (publication number CN102944966B) applied for in 2012, the induction layer and the curtain layer are respectively driven to be wound by double-layer, double-axis, and double-motor, although it It can solve the problem of curtain wrinkling during the winding process, but it will increase the weight of the entire device, which is inconvenient to carry and increases power consumption;
[0007] (3) In actual use, interactive whiteboards are more widely used. For example, an interactive electronic whiteboard (publication number CN207690056U) filed in a patent in 2018 mentions the use of interactive electronic whiteboards, but the whiteboards are heavy Large size, inconvenient to carry and high cost

Embodiment 1

[0048] Such as figure 1 Shown is an interactive curtain, which can be used for example to display presentation content, as an interactive layout, etc., for example, to display presentation content as an example, and input information by touch during use, then, the interactive curtain Including sensing screen 10, touch signal processing board 11, main board 12 and terminal electronic equipment 13; Sensing screen 10 includes screen base cloth 101, upper film and bottom film (upper film and bottom film are not shown in accompanying drawing); Wherein curtain The base fabric 101 is woven from rigid conductive yarns mixed with rigid fibers, which can generate capacitive signals when touched; the upper film and the base film are respectively attached to the upper and lower surfaces of the screen base fabric to achieve a good display effect.

[0049] Such as figure 2 As shown, the first direction of the rigid conductive yarn is set as the warp direction, and the second direction is ...

Embodiment 2

[0058] The overall structure of the interactive screen in this embodiment is the same as that in Embodiment 1, the difference is that in this embodiment, in order to be able to combine one or more of the rigid fibers with one or more of the conductive fibers mixed together to make yarn, the specific weaving process is as Figure 5 Blended Yarn Weaving Process II shown:

[0059] Firstly, the rigid fiber and conductive fiber are respectively opened, mixed evenly, and combed to make rigid fiber sliver and conductive fiber sliver, and the rigid fiber sliver and conductive fiber sliver are matched in proportion on the drawing frame, and after three parallel processes After slivering, a cooked sliver mixed with rigid fibers and conductive fibers is made, and then the cooked sliver is made into a blended yarn through roving and spun yarn processes. The roving and spun yarn crafts here are traditional crafts, so I won’t repeat them here.

Embodiment 3

[0061] The overall structure of the interactive screen in this embodiment is the same as that in Embodiment 1, except that the rigid conductive yarn is made of conductive filaments 202 and twisted rigid filaments or yarns 201 .

[0062] The material of rigid filament or yarn 201 used therein can be carbon fiber, basalt fiber, ordinary glass fiber, quartz fiber, ceramic fiber, boron fiber, and the material of conductive filament 202 used can be metal, conductive polymer, carbon, Conductive metal compound, silver-plated fiber; the number of twisted filaments or yarns can be arbitrary.

[0063] Such as Figure 6 As shown, through the parallel twisting process, the rigid filament or yarn 201 and the conductive filament 202 are parallel twisted to obtain a rigid conductive strand; Figure 6 As shown, only one rigid filament or yarn 201 and one conductive filament 202 or yarn are twisted together, but it is not limited to this situation, and the number of filaments or yarns can be ...

Abstract

The invention discloses an interactive curtain. The interactive curtain comprises a sensing curtain, a touch signal processing board and a main board; the sensing curtain comprises curtain bottom cloth, an upper surface film and a bottom film. The upper surface film and the bottom film are attached to the upper surface and the lower surface of the curtain bottom cloth respectively, wherein the rigid conductive yarns are connected and conducted with a circuit of the touch signal processing board to acquire capacitance signals generated on the curtain base cloth, and the touch signal processingboard is connected with the main board. The curtain has the advantages that the conductive yarns and the rigid fibers are woven in a mixed mode, the rigidity characteristic is added into the conductive yarns, the rigidity of the curtain is effectively improved, the surface of the curtain is smooth, a clear image is displayed, and curling and wrinkling are avoided, wherein the conductive yarns in two intersected directions form a small sensing area, a plurality of small sensing areas form a whole sensing function area, and a surface film and a bottom film are coated outside the sensing area torealize combination of the curtain layer and the sensing layer; the interactive curtain is light in weight, flexible, convenient to carry and simple in manufacturing method.

Description

technical field [0001] The invention relates to the textile field, in particular to an interactive screen. Background technique [0002] The interactive curtain is a high-tech product that integrates interactive teaching and broadband entertainment. It is an input device based on a PC with human-computer interaction functions. The interactive curtain can communicate with the computer and connect the curtain to the computer. , and use the projector to project the content on the computer to the screen. With the support of special applications, a large-screen, interactive collaborative meeting or teaching environment can be constructed, which is widely used in teaching, training, tutoring, high-definition Video entertainment, conference presentation, distance teaching and other fields. [0003] The interactive curtain uses specific interactive means such as finger touch, laser remote control, digital pointer, human body induction, etc., to run any application, or to edit, anno...
