Problems solved by technology

However, since the amount of light provided by the luminescent material is reduced due to the optical element, a decrease in brightness occurs
To prevent brightness degradation, higher power should be used, which results in increased power consumption

Abstract

The present disclosure relates to an electroluminescent display capable of reducing reflection of external light. An electroluminescent display according to the present disclosure includes: a substrate including a plurality of pixels, each pixel having a light emitting region and a non-light emitting region; a light emitting diode disposed in the light emitting area on the substrate; a packaging layer covering the light emitting diode; and a pattern layer including a light transmitting region corresponding to the light emitting region and a light blocking region corresponding to the non-light emitting region, and arranged in a first direction from the substrate, in which the first direction corresponds to a light emitting direction of light generated by the light emitting diode.

Description

technical field [0001] The present disclosure relates to electroluminescent displays that reduce reflection of external light. In particular, the present disclosure relates to electroluminescent displays that prevent reflection of external light without polarizing (optical) elements. Background technique [0002] Recently, various types of displays have been developed, such as cathode ray tubes (CRTs), liquid crystal displays (LCDs), plasma display panels (PDPs), and electroluminescent displays. These types of displays are used to display image data according to their unique characteristics and uses for various products such as computers, mobile phones, bank deposit and withdrawal devices (ATMs), and vehicle navigation systems. [0003] In particular, electroluminescent displays, which are self-luminous displays, have excellent optical properties, for example, in viewing angle and color realization, so that their application fields are gradually broadened, and they are attr...
