Problems solved by technology

However, this replacement resulted in the need to remove the outer insulating layer to connect the electronic components to the fabric, which was cumbersome because it added an extra processing step to the device's construction routine during which time due to the removal of the insulating coating The presence of chemicals and / or high temperatures may be required, the surrounding yarn may also be damaged

Embodiment Construction

[0031] refer to figure 1 , the first embodiment of the present invention will be described.

[0032] figure 1 A cross-sectional view of a woven textile 100 illustrating conductive weft yarns 140 in multiple layers of warp yarns 105 is shown. Multilayer warp yarn 105 of textile (or fiber) 100 includes first layer 110 , second layer 120 , and third layer 130 disposed between first layer 110 and second layer 120 . The yarns 111 and 112 of the first, second and third layers 110 , 120 and 130 are arranged along a so-called warp direction, thereby defining the multilayer warp threads 105 . The first layer 110 comprises conductive yarns 111 electrically isolated from each other by at least one electrically insulating yarn 112 . In this embodiment, two adjacent conductive warp yarns 111 of the first layer 110 are electrically isolated by three electrically insulating warp yarns 112 . Second and third layers 120 and 130 include electrically insulating yarns 122 and 132, respectivel...

Abstract

The present invention relates to textiles for photonic and electronic applications, particularly to multilayer textiles made of electrically conductive yarns for driving electrical components such as light emitting diodes connected to the textile. The light emitting diodes may be arranged in the form of an array in order to realize a flexible and foldable display. In the textile according to the present invention, insulating weft yarns are interwoven in a multilayer wrap (105) such that the electrically warp yarns (111) are partially covered by the insulating weft yarns (141), thereby preventing from short-circuit between electrically conductive yarns of the textile. In particular, the structure of the textile according to the present invention may be satin / sateen weave structure.

Description

technical field [0001] The present invention relates to textiles for photonic and electronic applications. In particular, the present invention relates to multilayer textiles made from conductive yarns used to drive electronic components, such as light emitting diodes, connected to the textile. Background technique [0002] Many types of textiles are already used in our daily lives, and new fields of application for these textiles have now emerged as electronic devices are integrated into these textiles. For example, photonic textiles such as fabrics incorporating light-emitting diodes (LEDs) open up a vast range of new interior and apparel applications, from lighting to atmosphere creation to communications. Very compact, low-power LED kits available as so-called surface-mounted devices can be attached to textiles by eg gluing, button fastening or sewing. This advantageously provides new types of displays such as foldable and flexible. [0003] The fabric substrates for ...
