Color filter array and organic light-emitting display device using the same

Abstract

The present invention provides a color filter array and an organic light -emitting display device using the color filter array. The color filter array can achieve the full light and red mixed lightcolor.The full -color color filter array is achieved based on the mixed light of the light wavelength and the light of the light of the blue wavelength and the light of the red wavelength of the blue wavelength and the red wavelength of the red wavelength.The red filter contains the first color conversion material for turning the light of blue wavelength to green and red light, and the green blocking material that blocks the green light.The green color filter contains the second color conversion material used to convert the light of blue wavelengths into green and red light, and the red blocking material that blocks the red light.The blue color filter includes red blocking materials for light that blocks the light of red wavelengths.

Description

[0001] This application claims the priority and benefit of Korean Patent Application No. 2005-131548, No. 2005-131549 and No. 2005-131550 filed in the Korean Intellectual Property Office on December 28, 2005, the entire disclosure of which is incorporated by reference here. technical field [0002] The present invention relates to a color filter array and a flat panel display device using the color filter array, more particularly, the present invention relates to a method capable of achieving improved luminous efficiency and color coordinates by mixed light of blue and red value of full-color color filter arrays and organic light-emitting display devices. Background technique [0003] In addition, the present invention relates to an organic light emitting display device in which a light emitting layer can be easily formed and a color coordinate value of the light emitting layer does not change greatly depending on driving voltage and current density. [0004] In general, a ...

Problems solved by technology

[0005] The problem with the three-color luminescence method is that the lifetime of any one color determines the lifetime of the entire system, the problem with the filter method is that the amount of light is reduced because the color filter absorbs the white light, and the problem with the color conversion method is that the color conversion is excited by blue light material, thereby reducing the contrast

However, the problem with this color light-emitting device is that it uses three wavelengths with poor luminous efficiency and color purity of red light, the color coordinate value of the three-color light source is seriously deformed, and its manufacturing process is complicated.
