Product Description
Customizable Windows And Keys For Enhanced Display And Functionality On High-Performance LCD Membrane Switches
High-performance LCD membrane switches can be enhanced with customizable windows and keys to improve display and functionality. Here's a breakdown of the features and considerations for these switches:
1. Customizable Windows
- Materials: Windows are commonly made with clear or transparent materials to view LCDs or displays [1]. They can also be made with tinted or colored dyes to produce filters [1].
- Finishes: Windows can have different gloss levels, including anti-glare finishes for outdoor use [1]. They can also have a matte finish [1].
- Integration: Windows are integrated into the graphic overlay of the membrane switch [2]. The other layers of the switch have cut-outs in the window's position [2].
- Optical Bonding: Windows can be optically bonded to add thickness and durability and to prevent damage [1].
2. Customizable Keys
- Tactile Feedback: Keys can be designed with tactile feedback using metal domes or embossing to provide a crisp effect when pressed [3][4].
- Programmable keys: LCD keys can be programmed to perform different functions [5].
- Backlighting: Keys can be backlit using LEDs, fiber optics, or electroluminescent panels for better visibility in low-light conditions [6][7].
3. Membrane Switch Technology
- Construction: Membrane switches are made of a printed polyester or polycarbonate overlay adhered to a printed circuit [4]. They are momentary action switches, meaning the circuit is closed only when the switch is pressed [4].
- Materials: Conductive inks made of silver or carbon are used to print the circuitry [4][8]. The circuit can also be etched copper on a Kapton flex [4].
- Durability: Membrane switches are known for their durability and resistance to moisture, chemicals, and extreme temperatures [9][10]. They can withstand actuation testing of millions of cycles [10].
4. Key Considerations for Design
- Application: Consider the environment where the switch will be used, such as whether it will be exposed to moisture, chemicals, or extreme temperatures [6][9].
- User Experience: Determine the desired user experience, including whether tactile feedback is needed and how the keys will be used [9][11].
- Visibility: Consider the need for backlighting or other features to improve visibility in low-light conditions [6][9].
- Customization: Membrane switches offer a wide range of customization options, including graphics, colors, textures, and embossing [9][11].
5. Additional Features
- Display Windows: Membrane switches can be designed with clear or transparent windows for viewing LCD or LED displays [1][2].
- EMI/RFI Shielding: Shielding can be added to protect sensitive electronics from interference [9].
- Waterproof Design: Membrane switches can be designed to be waterproof for use in harsh environments [7][10].
Membrane Switch specification:
| Overlay material ---For front or face overlay | ||||||||
| Polyester | Polycarbonate | |||||||
|
1 Highly versatile for embossing 2 Highly resistant for chemicals 3 Better durability 4 For internal and external use |
1 wide range of the surface finishes and thicknesses 2 More cost-effective 3 For internal and external use 4 many Lexan label choose |
|||||||
| Embossing --- Graphic overlay or up circuit can be embossed in order to insert metal stainless steel domes for good tactile when press .Leave space for mechanical keys and provide tactile indications | ||||||||
| Pedestal embossing | Rim embossing | Pillow embossing | Dim embossing | |||||
| Windows or LCD --- For display functions | ||||||||
| Printed colors windows such like red ,black and so on | Transparent finishes windows | |||||||
| Keys | ||||||||
| Tactile Keys :witch metal domes or Poly domes ,Metal dome with different diameter and pressure kinds | Non-tactile keys: printed silver spot on the circuit | |||||||
| LEDs ---Miniature LEDs ,LED colors :white ,Green ,Red ,Blue ,Yellow ,Orange and others | ||||||||
| EL and Sensors or inductors --- EL can be light any place where where you like ,and sensors can be used as LEDs | ||||||||
| Cables --- is extension of circuit and communication with your device | ||||||||
| Screen printing conductive silver cable | Copper plated cable /Polyimide or FPC | PCB cable | ||||||
| Types of connector --- 1 Zero insertion force(ZIF) with 0.5MM ,1.0MM,1.25MM pitch ;2 Female connector with 2.54MM pitch; 3 Male connector | ||||||||
| Shielding --- For protection function | ||||||||
| Gasket seal/Waterproof :protect the conductors against from the humidity and splashes | EMI/RFI/ESD Shielding: use an Aluminum foil shielding /clear ITO electrical conductive polyester to protect | |||||||
| Rear Adhesive --- Mostly use the 3M double-side mounting glue brand of USA. Also accepted others such like Lohmann and others | ||||||||
| Back plate --- Use in Aluminum ,Polycarbonate ,Acrylic Or PMMA | ||||||||
| Matching color --- PMS or RAL Is best ,CMYK or RGB also can be ok if you can supply PMS Or RAL | ||||||||
