General Information
Can I use 4D-UPA/gen4-PA to connect another device to a display module?
Yes. The display breaks out the available pins from the display module.
However, keep in mind that these products are primarily meant to program the displays and breaking out the extra pins is an additional feature.
On that note, the 5-way interface included in both programming adaptors which is labeled:
- 5-Way Interface (gen4-PA)
- uLCD/uOLED (4D-UPA)
is meant to program uLCD and uOLED products, not to breakout the display's 5-way interface.
Therefore, if you need to breakout the Serial UART pins that are also used for programming, it is recommended to use a gen4-Breakout board or integrate the display directly to your application board.
Do you have 3D Models of your products?
You can usually find 3D Models in the downloads section of each product page. If you cannot find any, please contact our support team to check if it is available.
Can I power Goldelox display modules with 3.3-volts?
All of our Goldelox-based display modules have on board protection diodes and 3.3V regulators, they have forward voltage drops. Therefore you 'need' to provide 5 volts to the display modules.
That being said, it is possible to power Goldelox modules down around 4V, sometimes a little lower. By powering the 5V pin as normal there is a diode in series for protection, but by powering the 5V_OUT pin, this is after the diode, so a slightly lower input voltage can be tolerated. Refer to the Schematic in the module Datasheet to see what is actually happening. It will get to a point where the 3.3V regulator will no longer be regulating, and will simply pass the input voltage, however the module may still run correctly. You may have success at 3.3V using the 5V_OUT pin as the input, however you will need to test this yourself. This is not endorsed by 4D Systems, but you are welcome to try at your own risk.
Do you offer displays with tempered glass?
Yes. Our capacitive touch displays and non-touch with cover lens bezel displays feature tempered glass rated 6H. These come in different sizes. The capacitive displays also comes in two mounting options, screw holes (CT) or cover lens bezel (CT-CLB). We can offer tempered glass customization with the possibility of changing the 6H tempered glass into Gorilla glass, upon consultation. The displays with cover lens bezel (CLB) can also be customized with logos and branding in various colours. please contact our sales team.
Do you offer branding customizations?
We can offer branding customizations with our displays with cover lens bezel (CLB) which may include logos and text in various colours. Our CLB customization may also include upgrading to a higher rated tempered glass or Gorilla glass options. please contact our sales team.
Can you provide some details regarding the lifespan of the resistive touch panel?
The Display Endurance specification is listed on the product datasheet and shown in the table below.
Table
| Display Endurance | Hours of operation measured when the display is 50% original brightness | 3000 hour |
| Touch Screen Endurance | Number of touches/hits with a 12.5mm tip at a rate of 2x per second with 250gf force | 1M touches |
| Slide Stylus on screen, 100 gf force 60 mm/s speed with a 0.8mm polyacetal tip stylus pen | 100K slides |
Although we currently do not have figures on the MTBF of the resistive panel or anything similar, our products have been extensively used as HMI's for various types of machinery which operate 24/7 for years on end.
Do you have any waterproofing recommendations for gen4 display modules?
It can easily be achieved by utilizing display modules that have a capacitive touch with Cover Lens Bezel (CLB) which can provide sufficient protection given that the perimeter is sealed.
For applications that use resistive or non-touch display module, the best practice is to add a thin transparent membrane that can be effectively fused to the enclosure and then place the display in front of it.
The membrane must be clear and flexible enough for use with the display. Likewise, just using sealants around the edges is not a good way as it can affect touch capability.
Do you have any waterproofing recommendations for uLCD/uOLED/pixxiLCD display modules?
The best practice is to add a thin transparent membrane that can be effectively fused to the enclosure and then place the display in front of it.
The membrane must be clear and flexible enough for use with the display. Likewise, just using sealants around the edges is not a good way as it can affect touch capability.
What is the storage life of your display modules with respect to the storage condition?
The display modules can be kept for years as long as they are not stored in a damp environment or outside the recommended storage temperature. Please refer to the product datasheet for more information.
