Abstract
The utility model relates to an organic electroluminescent display screen and a lighting adopting the screen. The organic electroluminescent display screen comprises a transparent base plate, an encapsulation sheet and an organic electroluminescent device, wherein the organic electroluminescent device is sealed between the transparent base plate and an encapsulation cover, and the outer surface of the transparent base plate used for deviating from the organic electroluminescent device is coated with a color filtering film layer. The organic electroluminescent device of the utility model can regulate the illumination color of a screen body through regulating the color of the color filtering film layer of the outer layer of the device, and in addition, the preparation process is very simple. The lighting of the utility model can be made to present various illumination colors.
Description
Technical field
The utility model relates to field of optoelectronic devices, relates in particular to display screen and lamp decoration.
Technical background
Organic electroluminescence device (OLED) has lot of advantages and possesses extremely strong competitive power as a kind of new display spare and existing main flat-panel monitor liquid crystal phase ratio.The general structure of organic electroluminescence device comprises successively: matrix, anode, organic layer, negative electrode, organic function layer comprises emission layer (EML) again, can also comprise hole injection layer (HIL) and/or hole transmission layer (HTL) between anode and emission layer, and electron transfer layer between emission layer and negative electrode (ETL) and/or electron injecting layer (EIL), can also comprise hole blocking layer (HBL) between emission layer and electron transfer layer etc.
The glow color of present OLED screen body is more single, because the illuminant colour coordinate of existing electroluminescent organic material is determined basically, and the self luminous color of luminescent material only limits to three primary colors more, is difficult to realize by single luminescent material such as pink colour, powder indigo plant, purple or the like at the special color color of dazzling.If prepare the organic electroluminescence device of rhythmo structure in order to regulate glow color, lose more than gain because complex process, cost are high.
Therefore, a kind of broken colour New O LED screen body luminous, that do not increase preparation cost again of can realizing of exploitation has very big meaning.
At present, colored lamp decoration all is to adopt the outer lampshade that variegates to realize that the effect that illumination shows is unsatisfactory basically.
Technology contents
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of OLED screen body that can realize multiple colorful light-emitting is provided, and a kind of colored lamp decoration that adopts this OLED screen body is provided simultaneously.
For achieving the above object, the technical solution of the utility model is:
A kind of organic EL display panel comprises transparency carrier, case chip, is sealed in the organic electroluminescence device between transparency carrier and the cap, and the outside surface that this transparency carrier is used to deviate from organic electroluminescence device scribbles color filter.
Above-mentioned color filter outside surface scribbles the packaging protection layer.
A kind of colored lamp decoration, comprise lamp socket, lamp body, circuit control device, this lamp body is an organic EL display panel, comprise transparency carrier, cap, be sealed in the organic electroluminescence device between transparency carrier and the cap, the outside surface that this transparency carrier is used to deviate from organic electroluminescence device scribbles color filter.
Adopt the organic electroluminescent screen body of the technical solution of the utility model preparation, can regulate the glow color of screen body by the color of regulating color filter, and preparation technology is very simple, after having prepared organic electroluminescence device, prepare last layer colour filter film in the outside surface of the device substrate technology by spin coating and promptly can finish.
Description of drawings:
Fig. 1 is a screen body structure synoptic diagram of the present utility model; (A) be sectional view, wherein 1 is that transparency carrier, 5 is case chip, wherein 2,3 and 4 anode layer, luminescent layer and the cathode layers that are respectively in the organic electroluminescence device; wherein 6 is color filter, and 7 is the UV diaphragm as the packaging protection layer.(B) be vertical view, wherein 61 is yellow colour filter film, and 62 is purple colour filter film, and 63 is green colour filter film, and 64 is pink colour colour filter film.
Fig. 2 is the structural representation of colored lamp decoration of the present utility model.
Embodiment:
Embodiment 1:
Specifically introduce preferred embodiment of the present utility model in conjunction with Fig. 1 and Fig. 2:
At first prepare a White OLED light source, then at the yellow color film glue of the whole spin coating of the light-emitting area of light source, use the mask plate (mask) of given shape that the color film glue of yellow is exposed, 61 zones are not exposed, other regional exposure, use developer solution that the yellow color glue of exposed portion is removed, the yellow color glue in 61 zones keeps, and the back of developing is cured with 90 ℃ of color glue of the remaining yellow of baking.After the curing again at the color film glue of whole light-emitting area spin coating purple, use the mask of given shape that the color film glue of purple is exposed, 62 zones are not exposed, other regional exposure, use developer solution that the color film glue of the purple of exposed portion is removed, because the yellow color film glue in 61 zones has passed through hot setting before, so can not be removed yet, the color film glue in such 61 zones and 62 zones is retained, the color film glue in other zone is removed, be cured with 90 ℃ of bakings after developing, repeat above step and can obtain 61,62,63, the color film glue shape of the different colours in 64 4 zones, after the color glued membrane preparation of these four kinds of colors is finished, in order to increase wearing quality, the top more water white UV glue of whole spin coating one deck uses UV radiation exposure 1 packing of 365nm that UV glue is cured, through after the above step process, White OLED light source originally just can send the light of four kinds of colors in four zones.
In sum; though the utility model discloses preferred embodiment as above; but can not be in order to conduct to qualification of the present utility model; those skilled in the art is not in breaking away from spirit and scope of the present utility model; any change and the modification made all should be considered as not exceeding the scope that the utility model claims are protected.
Claims (3)
