Abstract

The invention belongs to the technical field of flexible displays and particularly relates to a flexible reflection type cholesteric liquid crystal display and a preparation method thereof. The method comprises the steps of determining conditions for controlling cholesteric liquid crystal screw pitches to form target red wavelengths, target green wavelengths and target blue wavelengths; coating a conducting layer on a first layer flexible substrate, enabling at least one pixel jointly composed of reflection red liquid crystal, reflection green liquid crystal and reflection blue liquid crystal to be formed on a second layer, and enabling part of the reflection red liquid crystal, the reflection green liquid crystal and the reflection blue liquid crystal to be designated parts, to be separated from each other and not to interfere with each other. The cholesteric liquid crystal with target blue wavelength screw pitches reflects blue, the cholesteric liquid crystal with target green wavelength screw pitches reflects green, and the cholesteric liquid crystal with target red wavelength screw pitches reflects red. Liquid crystal molecules are fixed in a designated area of the flexible substrate in a spray coating mode. The preparation method is simple and convenient to apply and can improve production efficiency and reduce processing cost.

Description

technical field [0001] The invention belongs to the technical field of flexible displays, in particular to a flexible reflective cholesteric liquid crystal display and a preparation method thereof. Background technique [0002] Today, the application of LCD screens is developing rapidly. The applications on displays have spread to all aspects of people's lives, from computers and mobile phones to large-scale display screens in squares, to home TVs, car TVs, and car navigation screens. The development has shown an unstoppable torrent, its functions are becoming more and more perfect, and its application range is constantly expanding. Flexible LCD screen is one of the directions. [0003] Today's flexible screens are not widely used. Although the existing screens have clear principles, they have disadvantages such as small bending curvatures, repeated bending failures, and easy flow of liquid crystals in them. [0004] In the industrial production process of the application,...
