I want to understand where oled technology has reached and what i can do with it as a large computer display, rather than as a mere fixture for lighting purposes.
My client is a major subway system located in brazil.
My dream would be to hear from experts that the oled technology is at a point that all of the subway's backlit or frontlit poster frames (analog) including in-train pannels (curved surfaces) can be replaced by digital counterparts -- oled films -- that would turn that space into a sizzling streaming video showcase for advertising clients.
What would it take to do this?
Specifically, can oled panels be hardwired to a computer that in turn is connected via wi-fi or 3g mini-modem to our ad-serving network so we have realtime control of what is showing?
If i am dreaming too high application-wise, then what would be the next best alternative?
I look forward to hearing from you.+8 Other Responses
We need a led street light design specialist who can use existing drivers, optics, engines and leds to design street lights which can be certified to ul and other standards. Also should be able to do design lights for architectural use, bulbs, area lights+4 Other Responses
Display Screen Technology
Regarding a major university project involving the preliminary testing of a new display screen technology:
one of the requirements for that display involves the use of non-standard primary rgb wavelengths different than those used in typical displays. However, before they spec and build a new tft assembly, they need a testbed assembly where they can test (among other things) the effects of a number of slightly different wavelength combinations that create the phenomenon that is central to the project.
For example, that testbed for allowing them to test the use of various primary display wavelengths in the larger assembly could be:
1. An ordinary edge-lit lcd display whose light source is replaced by a filtered or otherwise discrete light source emitting only (within a reasonable fwhm) those desired non-standard wavelengths. It’s a lab testbench so form factor is not a limitation. Also, and fortunately, the non-standard wavelengths have adequate magnitudes in the wavelength/irradiance curves of factory cie-typical screen color filters. Thus, the existing screen filters, without modification, will allow transmission of the non-standard wavelengths (although project programmers will have to adjust image pixel brightness to attain a normal magnitude). However, the new light source’s wavelengths need to be somewhat adjustable (e.G., by filter selection, color source replacement or frequency shifting such as is possible with diffraction based and wheel-based color sources). Or that testbed could be…
2) a modified dlp projector whose original color wheel filters can be replaced with notch filters for the desired non-standard wavelengths. Or…
3) the contractor may propose a better means for testing the results of a screen that uses non-standard primary wavelengths. Preferably equipment used will be made up of, as much as is possible, existing, albeit modified, components.+10 Other Responses
