Abstract

The invention provides a thermotropic display element, which comprises a sealed shell, a first heating element and a second heating element, wherein the sealed shell comprises an upper substrate and a lower substrate which are oppositely arranged; the first heating element is arranged on the upper substrate; and the second heating element is arranged on the lower substrate. The upper substrate has a semitransparent structure and comprises a first surface and a second surface opposite to the first surface. The thermotropic display element also comprises a color material layer, wherein the color material layer is arranged inside the sealed shell and is converted through phase change between the upper substrate and the lower substrate under alternative heating action of the first heating element and the second heating element. The invention also provides a thermotropic display device which applies the thermotropic display element.

Description

technical field [0001] The invention relates to a thermotropic display element and a thermotropic display device using the thermotropic display element. Background technique [0002] Currently, electronic paper is a commonly used display device that does not require a backlight source. Electronic paper is a new type of information carrier. Since it can replace traditional paper, it has broad application prospects and great commercial value in various fields such as advertisements, newspapers, and books. The electronic papers currently on the market mainly use electrophoretic display technology. Electrophoretic display technology includes microcapsule electrophoresis technology, microcup electrophoresis technology and electronic powder fluid technology. [0003] Microcapsule electrophoresis technology is to encapsulate black and white charged particles and electrophoretic medium in a microencapsulated droplet structure to form microcapsules, and then set a conductive backpl...
