System for displaying images and method for fabricating the same
View Patent ↗Systems for displaying images and fabrication method thereof are provided. A representative system incorporates an electroluminescent device including light emitting units emitting lights with different luminescent intensities along light emitting paths thereof, formed overlying a substrate. And a compensation layer is disposed along the light emitting paths to adjust the different luminescent intensities for outputting substantially uniform light.
1. A system for displaying images, comprising: an electroluminescent device comprising: a substrate; light emitting units emitting lights with different luminescent intensities along different light emitting paths thereof, formed overlying the substrate; and a compensation layer disposed along the light emitting paths to adjust the different luminescent intensities of the light emitting units to output substantially uniform light intensity between the different light emitting paths, wherein the compensation layer is an irradiated photosensitive layer with different transmittance in different regions formed by irradiating a photosensitive layer.
2. The system as claimed in claim 1 , wherein the light emitting units serve as pixels or subpixels.
3. The system as claimed in claim 1 , wherein the compensation layer comprises a first region with a lower transmittance and a second region with a higher transmittance, wherein the light passing through the first region has a higher luminescent intensity and the light passing through the second region has a lower luminescent intensity, thereby outputting the substantially uniform light.
4. The system as claimed in claim 1 , wherein the irradiated photosensitive layer is made of a negative film, a conjugated polymer or a silver-containing compound.
5. The system as claimed in claim 1 , wherein the compensation layer is disposed overlying the light emitting units or underlying the substrate.
6. The system as claimed in claim 5 , further comprising a covering layer formed over the compensation layer overlying the light emitting units or formed between the light emitting units and the compensation layer overlying the light emitting units.
7. The system as claimed in claim 1 , wherein the irradiated photosensitive layer comprises a fixed property with different transmittances in different regions.
8. The system as claimed in claim 1 , wherein the light emitting units comprise a light emitting layer sandwiched between a lower electrode layer and an upper electrode layer.
9. The system as claimed in claim 8 , further comprising a dielectric layer formed on the upper electrode layer.
10. The system as claimed in claim 8 , wherein the electroluminescent device is a top emission type organic electroluminescent display device and the upper electrode layer is transparent.
11. The system as claimed in claim 8 , wherein the electroluminescent device is a bottom emission type organic electroluminescent display device and the lower electrode layer and the substrate are transparent.
12. The system as claimed in claim 1 , further comprising a display panel, wherein the electroluminescent device forms a portion of the display panel.
13. The system as claimed in claim 12 , further comprising an electronic device, wherein the electronic device comprises:
the display panel; and
an input unit coupled to the display panel, operative to provide input to the display panel such that the display panel displays images.
14. The system as claimed in claim 13 , wherein the electronic device is a mobile phone, digital camera, PDA (personal digital assistant), notebook computer, desktop computer, television, car display, or portable DVD player.
15. The system as claimed claim 1 , wherein the electroluminescent device is an organic electroluminescent device.
16. A system for displaying images, comprising: an electroluminescent device comprising: a substrate; a plurality of light emitting units comprising at least first and second light emitting units formed overlying the substrate, wherein the first light emitting unit emits light having a first luminescent intensity along a first light emitting path thereof, and the second light emitting unit emits light having a second luminescent intensity along a second light emitting path thereof, wherein the second luminescent intensity is different from the first luminescent intensity; and a compensation layer disposed along the first and second light emitting paths to adjust the respective first and second luminescent intensities of the first and second light emitting units to output substantially uniform light intensity between the first and second light emitting paths beyond the compensation layer, wherein the compensation layer is an irradiated photosensitive layer with different transmittance in different regions formed by irradiating a photosensitive layer.
