  • OLED Touch Displays?

    The OLED product line doesn't seem to have any touch displays. I do see in 4D Workshop, profiles for two OLED touch displays, the uOLED-32024-P1T and uOLED-32028-P1T, but they are not in the website's product listing. Are OLED displays less suitable as touch displays than TFT displays?

    Not really, it's just that the current OLED displays are quite small, hence not that suited to touch.

      The uOLED-32028-P1T profiled in 4D workshop is sufficiently large at 2.8" but it's not listed in the products on the website. Is it out of production?

        We have had difficulty obtaining these displays for some time.

        Please contact sales at 4dsystems dot com dot au to see if there any currently available.

          We are in the planning stages of our product development and need a solution we can count on obtaining as needed. Any plans for upcoming OLED touch in your regular lineup?

          I see that OLED touch panels are starting to come around. Many are available in the 3.3" size range as replacement OLED touch panels for newer cameras.

            Can you point out some of these 3.3" displays and reliable suppliers?

            We have not been able to locate a reliable supplier of the larger OLEDs in recent times.

            We do have a fair quantity of the 2.8" AMOLEDS available, contact sales for more information

              I have no direct experience but these two manufacturers seem to be carried by a lot of suppliers and they list several large OLEDs..

                Um, where?

                I couldn't find color oleds of that size on either of those sites, most seem to be monochrome

                  Ah I see, you're correct.

                  We're having difficulty finding a touch display package that is good for night time viewing, back-lit LCD is not working for us. A large monochrome OLED would work for our application but we may just separate our display into two sections; a static back-lit screen-printed film for control buttons, and a 4d Systems 1.7" microOLED for dynamic display, both sharing a single 4-wire touch panel.

                  Also, our users don't want our product to become unusable if the display breaks and they become unavailable to replace in the future. We're hoping to find an OLED display that will be in production well into the future, or to go with a size OLED that future OLEDs will likely be available in.

                    I presume the backlight is becoming too obvious for night time viewing? Using PWM to dim the backlight is probably a good solution to that.

                    Nobody really wants their product to become unusable, but the unfortunate truth is that the availability of a particular model is driven by sales of, say, millions per month. As soon as sales drop below that manufacturers start looking to stop production and chase the 'next big thing'.

                    Some relief can be achieved by having large stock levels or paying a premium for a small production run, but do you really want to go there?

                    We try to make sure we can ensure a good supply of any display we bring to the market before we bring it to market, but even then we can be exposed to situations beyond our control.

                      Yes, it's a low light application and the backlight washes out vision in the dark. The lack of LCD contrast and viewing angle is also an issue here, so we really are looking to OLED.

                      It turns out now that we would be using a separate screen printed film for the buttons, we would need just a small OLED for feedback display. The 0.96" would do the job just fine. If we start with this size, and slightly enlarge our display space, maybe we could accommodate some size variance of future OLEDs. Is there any indication that you will continue to be able to offer your OLED solutions in the ~1" size range?

                        Our uOLED-96 has been going strong for over 5 years and there are no plans to discontinue this product.

                          Thank you. Sorry about all the questions, trying to iron out the details before we procees. Now we're looking to go with the uOLED-160-G2. Same question as before.. is there any indication that you will continue to be able to offer your OLED solutions in the 1.5-1.8" size range in the about same proportion (not square)?

                            Same answer for the 160-G2, it is currently available for the foreseeable future.
