Problems solved by technology

At present, an elastic material is usually used, which has a certain amount of elastic modulus. If the elastic modulus is too large, the user experience of the stretching device will be poor; if the elastic modulus is small, the substrate will be overstretched and The deformation of the substrate will cause greater frictional damage to the display elements and metal wires, thereby greatly reducing the service life of the display device

Abstract

The invention discloses a stretchable display device and a manufacturing method thereof. The display device comprises a substrate, a display element, a conducting wire and a first coating layer, wherein the display element and the conducting wire are arranged on the substrate, the first coating layer covers the display element and the conducting wire and has a first elastic modulus, the conductingwire is electrically connected with the display element, the first coating layer and the substrate are positioned on two opposite sides of the display element, the display device further comprises asecond coating layer, the second coating layer completely coats the first coating layer, the display element and the conducting wire, the second coating layer has a second elastic modulus lower than the first elastic modulus, and the first coating layer is close to the display element than the second coating layer. The display device provided by the invention is good in user experience and long inservice life.

Description

technical field [0001] The invention relates to a stretchable display device and a manufacturing method thereof, specifically belonging to the field of display technology. Background technique [0002] Currently, stretchable display devices are being used more and more. However, it is necessary to avoid damage to the rigid components of the device caused by the user's excessive force when stretching, and elastic substrate materials are usually used to solve the above problems. The modulus of the elastic backing material plays a key role in the protection of the rigid material, so choosing the right modulus backing material is critical. At present, an elastic material is usually used, which has a certain amount of elastic modulus. If the elastic modulus is too large, the user experience of the stretching device will be poor; if the elastic modulus is small, the substrate will be overstretched and The greater the degree of frictional damage to the display element and the met...
