LCD module

Graphical LCD and Touch user interfaces

Using graphical LCD displays - conveniantly and from arbitrary hardware

The modules of the LCM2 series are an optimized design for featuring an ergonomic user interfaces for existing devices or those to be developed. They can be interfaced from arbitrary devices using a serial interface. Even low-powered 8-bit microcontroller will be able to do this job nicely. The serial communication follows a master-slave scheme: The device of our customer controls the base application and communicates as a master with the LCM2 module. The module then executes the graphical instructions sent by the master.

Interaction with the module can be achieved appropriately to the conditions and the environment of the application: Frequently, an integrated touch glass is the solution of choice, because this allows the user to interact very intuitivly and flexibly with the application. If a touch glass cannot be used (e. g. in a dirty environment) the modules allow interfacing encoders or a key matrix.

For your project requirements we offer the following modules:

• LCM2 module of the "": For these modules properties important for industrial applications have been especially considered, e. g. a long-term availability of the displays chosen and the use of different power supply voltages. Monochrom-, Color-STN- and Color-TFT modules are available wiht 5,7-inch displays. Additional Color-TFT module in sizes of 3,5 inch, 4,0 inch and 5,0 inch are being developed.
• LCM2 modules of the "" are designed for the use in price sensitive projects. Color TFT displays of size 3,5 inch and 5,7 inch are available.

The LCM2 user interface modules come with a resolution of 320 x 240 Pixels in monochrome, color (passiv or TFT). Modules with a resolution of 640 x 480 pixels are under development.

Typical properties of LCM2 modules:

• Software functions for the design of an attractiv graphical user interface (GUI Interpreter).
• Good compatibility to the functions of the GUI library.
• Interface for optical or mechanical encodes (up to 2 channels, "Jog-Dial")
• Interface for key matrix (up to 3 x 4 keys)
• Piezo buzzer for signals and supporting touch input
• 2 MB Flash for storing binary objects (e. g. graphics)
• Serial interface with logical level, RS-232, RS-422 / RS-485 or USB
• Voltage range between 5 and 24 V.
• Temperature range: 0 to 55 Celsius or -20 to70 Celsius, depending on the display chosen.
• EMC optimized design, 4-layer PCB.
• Comprehensive support services.

For the LCM2 modules starterkits are available. These help to start developing quickly and also allow to do the complete application development.

Long term availability of the LCM modules

In our LCM2 modules of the "Industrial Line" we employ LCD displays, which are used primarily in the industrial sector. These displays thus do not suffer from the the typical short-term product cycle of consumer products and are available for a longer period. This helps to have the option of obtaining the modules (including "last buy" options) for some 5 years or longer.
Generally and also for users of the "Economy Line" modules the following applies: Even after a certain display has been discontinued our modules can be delivered with a suitable replacement display without the need for our customer to change his application program. This is because the software protocol at the serial interface can be maintained unchanged, even if the hardware needs to be changed. As all LCM2 modules use the same software protocol, this, in addition to providing more secure planning for the future of your product, also gives the flexibility to easily change between the LCM2 modules available as needed.

Custom specific LCM2 modules

The LCM2 display terminals are based on a hardware and software platform. If your project needs to have the modules modified (e. g. another display or another communications interface), we will be glad to offer a solution optimized for your purposes. Please let us know what your requirements are.

Support:

We offer qualified support directly from the manufacturer, which does not leave you alone after aquiring our LCD modules. A detailled documentation, programming examples, and support via email and phone is available to help you realise your application rapidly.
