In this, the blue light that organic luminous zone 31 is launched converts green glow and ruddiness to by green conversion film 332 ' and red conversion film 333 ' respectively, then green glow and ruddiness are more respectively by green color filter 332 and Red lightscreening plate 333, use and promote green with red other color contrast, the blue light that while organic luminous zone 31 is launched utilizes drive circuit that the Red Green Blue that produces is combined into required full-color picture also simultaneously by blue color filter 331 at last.
Yet, in the full-color display floater 3 of prior art, because need to utilize the light shield processing procedure at least three roads to form green and red double-colored look conversion film 332 ' and 333 ' respectively on green color filter 332 and Red lightscreening plate 333, its processing procedure is comparatively complicated, cost is also higher.Simultaneously, because full-color display floater 3 must utilize planarization layer 32 so that the whole front panel planarization, make the thickness thickening of whole front panel also not meet light, thin, short, little trend.
In addition, with regard to practicality, full-color display floater must be expanded the range of application of display floater if can add the effect of mirror surface.At present, existing technology is attached to a reflective film on the screen of display floater, makes display floater can have the dual-use function of show image and reflected image.
Yet because reflectivity and the light transmittance of reflective film be inversely proportional to, that is when reflecting effect was good more, light transmittance was just poor more, and then made and the brightness deepening of display frame cause the operational puzzlement of user.Simultaneously, because reflective film is arranged on the display floater in the attaching mode, the situation of warpage taking place easily under long-time the use, also causes user's inconvenience.
The inventor urgently thinks a kind of " full-color display floater of minute surface " that can solve this problem of development based on the spirit of positive innovation, and several times research experiment is eventually to finishing the present invention.
Summary of the invention
Because above-mentioned problem, purpose of the present invention provides a kind of need not use planarization layer, do not need the full-color display floater of minute surface that uses the look conversion film of Red respectively and have the reflected image function.
Thus, for reaching above-mentioned purpose,, comprise an organic luminous zone, a white light modulating layer, a filter layer, a transparency carrier and a light transmissive reflecting layer according to the full-color display floater of a kind of minute surface of the present invention.Wherein, organic luminous zone has the pixel of several emission white lights; The white light modulating layer comprises a transparent protective medium, protective medium mix a fluorescent and/or a phosphorus; Filter layer is made of by the filter that a masking frame centers on several; Transparency carrier has a first surface and a second surface relative with first surface, and filter layer is formed on the first surface of transparency carrier, and the white light modulating layer is formed on the filter layer, and organic luminous zone is positioned on the white light modulating layer; Light transmissive reflecting layer is formed between the first surface of transparency carrier and the filter layer or on the second surface of transparency carrier.
For reaching above-mentioned purpose,, comprise an organic luminous zone, a white light modulating layer, a filter layer, a transparency carrier and a light transmissive reflecting layer according to the full-color display floater of a kind of minute surface of the present invention.Wherein, organic luminous zone has the pixel of several emission short-wavelength lights; The white light modulating layer comprises a transparent protective medium, protective medium mix a fluorescent and/or a phosphorus; Filter layer is made of by the filter that a masking frame centers on several; Transparency carrier has a first surface and a second surface relative with first surface, and filter layer is formed on the first surface of transparency carrier, and the white light modulating layer is formed on the filter layer, and organic luminous zone is positioned on the white light modulating layer; Light transmissive reflecting layer is formed between the first surface of transparency carrier and the filter layer or on the second surface of transparency carrier.Wherein, the short-wavelength light launched of several pixels of this organic luminous zone is ultraviolet light or blue light.
