AI Technical Summary

Technical Problem

Existing anti-counterfeiting labels are difficult for consumers to identify and are easily copied by criminals, leading to rampant counterfeiting and duplication, which seriously disrupts market competition and causes losses to manufacturers and consumers.

Method used

It employs a cholesteric liquid crystal cell, which features a transflective layer and a cholesteric liquid crystal layer on the cell. When illuminated from the front and back by a light source, it displays different colors. Combined with QR code scanning for verification, it enhances the anti-counterfeiting effect.

Benefits of technology

It achieves easy identification and difficulty in copying of anti-counterfeiting labels, enhances anti-counterfeiting effect, reduces production cost and does not require power supply, and improves the anti-counterfeiting function of anti-counterfeiting display panel.

Abstract

This invention discloses an anti-counterfeiting display panel and an anti-counterfeiting label. The anti-counterfeiting display panel has a graphic area and a background area. The anti-counterfeiting display panel includes a first liquid crystal cell, which includes a first substrate, a second substrate, and a cholesteric liquid crystal layer located between the first and second substrates. The first substrate has a reflective layer that transmits some light and reflects others. The reflective layer has a patterned structure corresponding to the graphic area, and the cholesteric liquid crystal layers corresponding to the background area are all in a reflective state; or the reflective layer has a patterned structure corresponding to the background area, and the cholesteric liquid crystal layers corresponding to the graphic area are all in a reflective state. By using a cholesteric liquid crystal cell and setting a reflective layer corresponding to the graphic / background area on the cholesteric liquid crystal cell, and combining this with the cholesteric liquid crystal layers corresponding to the background / graphic area being in a reflective state, when white light is shone from the front and back of the anti-counterfeiting display panel respectively, the graphic area and background area display different colors, enhancing the anti-counterfeiting features.
