Subverting imagination: LED clothing that can be worn on the body

Google Glass, Apple Watch... In recent years, the emergence of a variety of wearable electronic devices has stimulated the consumer market's focus on consumer wearable devices and consumer demand. What you can tell now is that in addition to being a small accessory, the electronic device can also be "dressed" directly on the body.

Recently, the Dutch research institute Holst Centre, the Belgian Microelectronics Research Center (IMEC), and the Institute for Microsystems Technology (CMST) of the Ghent University of Belgium funded by IMEC, and Panasonic have developed LED technology. A color flexible display that can be applied to a cloth and can be washed.

The display screen is an active matrix display using a compound InGaZnO TFT, the number of pixels is 32×32×RGB, the pixel density is 13 ppi, the pixel pitch is about 2 mm, and the average brightness is over 200 cd/m 2 , and the driving voltage is 7V. The substrate material is polyimide resin, and the sealing material is rubber, which can be directly washed on the cloth. Since the serpentine copper wiring is used between the pixels, it has good bending tensile resistance and stretchability.

The researchers said that the display manufacturing process uses mass production technology and can be quickly put into practical use. In other words, it is very likely that in the near future, LED fabrics will be available, and can be made into a variety of clothing, accessories directly on the body. By then, people can change the color and pattern of their clothes as they wish, creating a unique self.

In addition, this LED garment also provides an innovative means for stage performances. It can quickly change patterns and has a luminous effect that helps achieve a more fantastic stage effect.

Xiao Bian couldn’t help but think about it. If it is used in the military field, let the soldiers put on the clothing of this material, the military facilities cover it with this cloth, and take pictures of the soldiers behind or around the facilities and display them on clothing and cloth. Isn't it possible to achieve the effect of "invisibility"? This principle has been applied to the led display of outdoor buildings, creating the special effect of the building's "stealth".

Here, there is also a display material OLED, that is, an organic light-emitting material, which is also a novel material that can be bent and can display images, and is currently used in mobile phones, televisions, and wearable devices.
