LCD Key Technology

 

The industry leading LCD Key Technology from [E³] is based on four elements:

 

RGB Backlighting

[E³] leading innovation in LCD key technology includes full RGB backlighting in 64 or over 10,000 RGBcolors. [E³] not only allows you to select these color via software commands. We also use our proprietary calibration system to ensure that switches in a large panel array have uniform colors. This is achieved through our Advanced Technology™ electronics which control both the backlighting and LCD display in the switch.

Additional information on the RGB backlighting is available on the RGB Colors page.

LCD Display

LCD switches from [E³] use standard transmissive FSTN LCD displays for optimal contrast, viewing angle and readability. Inverse transmissive (SI Switches) and inverse transflective (SM Switches) LCDs are also available.

The Advanced Technology™ electronics control image refresh in the keyswitch so that no data communication is required until the image data changes. The electronics also maintain optimal contrast for best readability.

Advanced Technology™ Electronics

At the heart of the [E³] Key Technology is the Advanced Technology™ electronics designed and developed by [E³]. The electronics are integrated in each switch so that there is only minimal external hardware required to control the switches. A simple 2-wire SPI is the interface to the switches to download image data and set background colors.

The Advance Technology™ electronics also allow us to provide our customers with custom protocols.

Not only are the control electronics the most advanced in the industry, but [E³] has also incorporated a high degree of ESD protection that make the SA/SI/SM switches superior with regard to ESD/EMI.

Legacy Mode Compatibility

The SA3216 and SA3624 switches from [E³] offer a pin- and command-compatible replacement option for customers currently using LC16 and LC24 switches. The Legacy Mode™ allows for drop-in replacement without the need for any hardware changes. SA switches self-initialize and do not require a permanent clock.

In order for the SA switches to convert the legacy protocol for the SA switches only a timing and data word adjustment must be made.

For more information, please download this detailed description of the Legacy Mode here.

Mechanical Switch

The keyswitches from [E³] are not only intelligent, but tough. Mechanical design features such as over-travel protection, force distribution and long-life switch elements let the SA/SI/SM switches exceed already industry-leading durability ratings.
