Embodiment
For feature of the present invention, structure and effect are had further understanding and understanding, now be described in detail as follows with preferred embodiment and conjunction with figs.:
At first, see also Fig. 2, Fig. 2 is the generalized section of light color filtering conversion device of the present invention and organic electroluminescence display device one preferred embodiment thereof; As shown in the figure, light color filtering conversion device 30 of the present invention mainly is provided with at least one black matrix" 33 (Black Matrix) in the part upper surface of a transparent substrates 31, and be provided with a color converting layer 361 in the part upper surface that part upper surface and this transparent substrates 31 of black matrix" 33 is not provided with black matrix" 33, be not provided with on other position of transparent substrates 31 of this color converting layer 361 and then be provided with one first chromatic photoresist 351 and one second chromatic photoresist 353.Be coated with a smooth unit 37 that blocks in black matrix" 33, color converting layer 361, first chromatic photoresist 351 and second chromatic photoresist, 353 tops, for example a planarization layer (Overcoat) and/or a barrier layer (Barrier Layer), by this smooth setting of blocking unit 37, will help the setting of this organic electric-excitation luminescent (OLED) device 40.
The smooth upper surface part subregion of blocking unit 37 of this light color filtering conversion device 30 can be provided with the lower electrode 41 of at least one OLED device 40, and is provided with an organic light-emitting units 43 and a subtend electrode 45 in regular turn in the part upper surface of this lower electrode 41.Wherein, this organic light-emitting units 43 includes at least one first organic light-emitting units 431 and at least one second organic light-emitting units 433, and this first organic light-emitting units 431 is arranged at the vertical extent position of first chromatic photoresist 351, and second organic light-emitting units 433 then is arranged at the vertical extent position of this first chromatic photoresist 351, second chromatic photoresist 353 and color converting layer 361.By this, will have this first organic light-emitting units 431 on the vertical extent position of this first chromatic photoresist 351 and second the folded of organic light-emitting units 433 established.
When supply between bottom electrode 41 and the counter electrode 45 has an operating current, this second organic light-emitting units 433 will produce a secondary light source S2, and first organic light-emitting units 431 and second organic light-emitting units 433 that should folded establish then produce one the 3rd light source S3.Wherein, this secondary light source S2 will filter after penetrating second chromatic photoresist 353 and produce one second coloured light L2; This secondary light source S2 will be converted to one the 3rd coloured light L3 after penetrating this color converting layer 361; And the 3rd light source S3 will filter formation one first coloured light L1 after penetrating this first chromatic photoresist 351.Wherein, by the first coloured light L1, the second coloured light L2 of proper proportion and the mixing of the 3rd coloured light L3, can obtain the full-color display effect of this OLED display unit 400.
