AI Technical Summary

Technical Problem

Existing technologies are prone to problems such as poor jetting and peeling of color conversion ink layers in the inkjet process, resulting in loss of light efficiency and decreased brightness of image display devices.

Method used

A light-refracting layer with a lower refractive index is introduced between the light source and the color conversion ink layer. The refractive index difference is adjusted so that the refractive index difference between the light-refracting layer and the color conversion ink layer is greater than the refractive index difference between the light source and the light-refracting layer. The surface energy of the light-refracting layer is controlled within a specific range to form partitions to divide pixel areas.

Benefits of technology

It improves the brightness of image display devices, prevents poor jetting and ink layer peeling, reduces ink consumption, improves inkjet process characteristics, and enhances light utilization efficiency.

Abstract

本发明提供层叠体、上述层叠体的制造方法及包含上述层叠体的图像显示装置,上述层叠体包含基材、形成于上述基材上的光源、形成于上述光源上的光折射层以及形成于上述光折射层上的色转换油墨层,上述光折射层的折射率比色转换油墨层的折射率小0.3以上,上述光折射层与色转换油墨层的折射率差(第一折射率差)大于光源的最上部层与光折射层的折射率差(第二折射率差)。通过在光源与色转换油墨层之间包含折射率小于色转换油墨层的光折射层,且调节成使光折射层与色转换油墨层的折射率差大于基材与光折射层的折射率差,从而表现出进一步提高图像显示装置的亮度的效果。
