AI Technical Summary

Technical Problem

In existing AMOLED displays, the red, blue, and green filter units have low light conversion efficiency, resulting in high power consumption and low color gamut coverage.

Method used

1,5-substituted alkylamine anthraquinone red dye, 1,4-substituted alkylamine blue dye or hydroxyanthraquinone blue dye, and 1,4-substituted alkylamine anthraquinone green dye are used as filter unit materials, and their mass percentage content is controlled between 0.5% and 20%. Combined with the high refractive index design of the planarization layer, the matching of spectrum and color coordinates is optimized.

Benefits of technology

It improves the light conversion efficiency of the filter unit, reduces the power consumption of the display panel, and enhances the color gamut coverage and the color depth of the image.

Abstract

The present disclosure provides a display panel and a display device. The material composition of a red filter unit (201) of the display panel comprises a 1,5-substituted alkylamino anthraquinone red dye having a mass percentage content of 0.5-20%. The material composition of a blue filter unit (202) comprises a blue dye, the blue dye comprising at least one of a 1,4-substituted alkylamino blue dye or a hydroxy anthraquinone blue dye which has a mass percentage content of 0.5-20%. The material composition of a green filter unit (203) comprises a 1,4-substituted alkylamino anthraquinone green dye having a mass percentage content of 0.5-20%.
