NHD-2.7-12864UMY3 Mechanical Info
« on: August 21, 2015, 09:12:48 PM »
Greetings, I am using the NHD-2.7-12864UMY3 OLED display in my design. I am also in the process of creating my CAD symbols, schematic and PCB for the design. Now with the above mentioned part, it is not clear to me how this part is mechanically attached to the circuit board. In the data sheet I see what looks like 22 pin through holes. Now is this a connector or what? Do I need to use a molex or some such? Can you please advise. I am just unclear how this part attaches to my circuit. For my PCB CAD symbol should I just layout for something like a SIP 22, and what about any other mounting considerations like mounting holes, etc.
One more thing, I am having a hard time reading the verification images required to make a post and I am using a 25 inch monitor.

Thank you in advance for any assistance.

Hi,

The part is attached to the PCB through the bezel. To connect to the display you could use either the 22 pin through holes or use a Molex connector; which would be soldered to the pads beneath the 22 pin through holes. We do offer a service of attaching either connector to the display.

The PCB does have mounting holes on the corners; the mounting holes have a diameter of 2.5mm. You can see both the mounting holes and connections on a larger image of the display itself. Larger Image of NHD-2.7-12864UMY3

We will look into the issue you were having with the Capcha images.

Thanks, that image really clarifies things for me, and now I am not so sure that display will work out for me. Here is what I am doing and perhaps you might have a better idea what display would be more suitable. First, picture construction workers, and big burly guys using a handheld instrument. It can be used outdoors in sunlight or in a more darkened space. To be specific, I am working on a air gas monitor that will be used by both construction and general industry. The display has to be both easily readable, and very rugged (again think big burly guys). If a touchpad can meet the physical demands, then that would be great as it really simplifies the mechanical part, and size.

Can you make any suggestions?

Thanks a bunch

OLED displays are generally more rugged than traditional LCD's. But if you want something that sunlight readable, an OLED might not be the best way to go. If you are interested in this display we could supply a custom part where this display would come with a touch panel.  If you are interested in customizing this display please email us at nhtech@newhavendisplay.com

If you are looking at standard parts with a touch screen we do have our TFT displays that already come with a touch panel. We have a 2.4" Resistive Touch TFT, although the touchscreen does reduce the brightness considerably. We also have a new line of sunlight readable TFT displays that are coming out soon, if the physical size of the 3.5" Displays work for you; we will have a sunlight readable variant coming out with a touch panel as a standard part.

Thanks, I been doing others task lately so I got sidetracked on the display portion. I am once again looking into the display issue. The displays you mentioned above do not have the right form factor for me and I do not need color. One display that I thought might work is the NHD-12864WG-BTMI-V#N, or this one NHD-12864WG-BTFH-V#N-ND The image looks like a bright display and is about the size of a business card, which is good. Do any of these work well in sunlight? I do not have much experience using display technology, so I am slowly getting up to speed.

Also, I was wondering how well the resistive touch screens work with gloved hands?

Thank you

Hi mnauss,

NHD-12864WG-BTMI-V#N and NHD-12864WG-BTFH-V#N-ND are both transmissive displays meaning all of the light is provided from the backlight of the LCD Panel.

A transmissive LCD looks great in indoor environments, but can be quite dim when in direct sunlight.


I highly recommend you use NHD-12864WG-BTFH-V#N

http://www.newhavendisplay.com/nhd12864wgbtfhvn-p-1095.html

NHD-12864WG-BTFH-V#N is a transflective LCD, which is a combination of a transmissive and reflective LCD.

Feel free to contact me if you have any questions or concerns. :D

To answer your second question, yes resistive touch screens work with gloved hands  8)


The resistive touchscreen is the most common type of touchscreen. Except for modern smartphones, tablets and trackpads, most touchscreens we come in contact with are actually resistive touchscreens. As youíve probably guessed, the resistive touchscreen relies on resistance. In that respect, itís pretty intuitive to understand Ė the pressure you apply causes the screen to respond.

Hope this helps!
