Problems solved by technology

For example, cholesteric liquid crystals with Planar state and Focal-conic state have been widely used in e-books, display cards (recognition cards) due to their bistable states. However, the contrast ratio of this type of display product is usually not as good as expected, so how to improve the contrast ratio of this type of display product is one of the issues that technicians in this field pay attention to.

Abstract

A display, which includes a first substrate, a first electrode layer, a thermally sensitive bistable liquid crystal layer, a second electrode layer, a first conductive through hole, a first pad, a second conductive through hole and a second pad. The first substrate has a first surface and a second surface. The first electrode layer is configured on the first surface. The thermally sensitive bistable liquid crystal layer is configured on the first electrode layer. The second electrode layer is configured on the heat-sensitive bistable liquid crystal layer. The first conductive via penetrates through the first substrate. The first pad is disposed on the second surface and is electrically connected to the first electrode layer through the first conductive via hole. The second conductive via penetrates through the first substrate. The second pad is disposed on the second surface and is electrically connected to the second electrode layer through the second conductive via hole.

Description

technical field [0001] The present invention relates to a display, and more particularly to an electrically erasable and thermal recordable display. Background technique [0002] The multimedia technology in today's society is quite developed, most of which benefit from the progress of semiconductor elements or display devices. As far as displays are concerned, liquid crystal displays with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. Generally, liquid crystal displays can be divided into three categories: transmissive, reflective, and transflective. Different types of liquid crystal displays are used in different environments. [0003] At present, the application of liquid crystal displays in portable electronic products has gradually matured, such as smart phones, e-books, and display cards (identification cards, tickets, credit cards) and ...
