LED Backlight Screen Printing Rubber Membrane Keyboard With
Transparent Window Display
Features
- Construction: Composed of a thin, flexible membrane layer made of rubber or
silicone, which acts as the key switch.
- Key Press: When a key is pressed, the rubber dome collapses and makes
contact with a circuit board beneath, registering the keystroke.
- Sealed Design: Often designed to be spill-resistant and dust-proof, making them
suitable for various environments.
Advantages
- Cost-Effective: Generally cheaper to produce, making them affordable options for
basic keyboards.
- Quiet Operation: Rubber dome switches are typically quieter than mechanical
switches, which can be beneficial in shared spaces.
- Durability: Although they may not last as long as mechanical keyboards,
rubber membrane keyboards can withstand moderate use.
Disadvantages
- Typing Feel: Many users find the typing experience less satisfying compared to
mechanical keyboards, as the feedback can feel mushy.
- Key Response: The actuation may not be as precise, which can affect typing
accuracy for some users.
- Limited Lifespan: Rubber domes can wear out over time, leading to reduced
responsiveness.
Use Cases
Rubber membrane keyboards are commonly found in:
- Laptops: Many laptops use this technology due to space constraints and
cost considerations.
- Office Keyboards: Ideal for environments where noise and cost are concerns.
- Remote Controls and Other Devices: Frequently used in devices that require simple input without
complex features.
Specification:
1)Material (for front or face overlay)
Polyester:
1.Highly versatile for embossing
2.Highly resistant to chemicals
3.Better durability
4.For internal and external use, UV resistance
Polycarbonate:
1.Different surface(Glossy, Matt) and thickness(From 0.12mm~2mm)
2. cost-effective in price
3.For internal and external use
2) Embossing
Rim embossing/pillow embossing/dimple embossing
Graphic overlays can be embossed in order to insert domes/LED,
leave space for mechanical keys/LED and provide tactile indications
and better tactile feeling.
3)Windows(for display function)
1. print different colors windows, As transparent grey/Red/green
window for display
2. Clear/Transparent window for LCD display
2. Matt/semi-transparent window for LED
4)Keys/buttons
Tactile keys---with metal dome or poly dome
Non-tactile--silver printing dots with flat key
5) Embeded LEDs
Small, brilliant lights only about 0.02’’ in height. Avaliable in
several vibrant colors.
LED colors: white, yellow, orange, green, red, or double colors
LED.
6)Cable
It is an extension of the printed circuit and is used to
communicate with your device.
7)Types of connector
1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male
connector
8) EMI / RFI / ESD Shielding
use an aluminum foil shielding / a clear ITO electrical conductive
polyester
9)Adhesive
mostly used are 3M-double-side glue
10)Backplate-
in aluminum, polycarbonate, acrylic, PCB
