Touchpanel resistive and capacitive (PCAP)
We do provide for many graphic displays touch panel solutions from 102x32 up to 1280x800 dots: either as an accessory with self adhesive at the rear side or as ready made unit incl. driver and serial interface.
Resistive touchpanel provide an analogue voltage which is direct proportional to the touch position of finger. It's possible to put the touch panel behind a thin foil and operated with a pen or finger. Even thick hand gloves may operate perfectly.
Our capacitive touchpanel are equipped with an onboard controller, which provides directly all positions via I²C bus interface. A thin window or a thin glove do not prevent operation.

RS-232 interface
Many dot-matrix and graphics LCDs have only one option for connecting to an 8-bit data bus. If the data is to be transmitted serially (lack of ports, considerable distance), it is advisable to use an RS-232 interface. This interface then also handles the initialization and line management of text displays. Using an interface also considerably reduces the programming effort required with graphics displays as well.
- RS-232 interface for dot-matrix displays
The EA 9707-V24S board is suitable for all dot-matrix LCDs with HD 44780 (1x8 to 4x40 characters). It is a mere 80x32x14mm in size. The RS-232 connection is provided by a 10-pin connector, and there are 3 different 1- and 2-row soldering-eyelet strips available for connecting the display. The transmission rate can be set to 300, 1200, 2400 or 9600 bps. There is a contrast potentiometer on board. The supply voltage is +5V or +9-35V. You can download the full data sheet in PDF format here immediately. The price if you order 25 is 44.37 euros*) per item. An RS-422 interface and an integrated fixed-text memory for 64 pages with 6 digital inputs are available as options.
*) Prices quoted are inclusive of 19% sales tax.
- RS-232 interface for graphics displays
We can provide a suitable RS-232 interface for practically any graphics LCD in our range. We also offer some displays as fully configured graphics units. The different displays have resolutions of between 120x32 and 640x480 pixels. Each interface has a variety of integrated fonts and graphics functions that considerably simplify graphics programming, which can otherwise be really quite complex.

What are the advantages of capacitive touch displays compared to resistive touch panels?
Capacitive touch displays offer the advantage of being equipped with their own controller, which transmits touch data via an I²C bus interface. This enables more precise and faster touch detection compared to resistive touch panels. In addition, capacitive touch displays are less susceptible to wear and tear since they do not require physical pressure detection. They also work through thin glass or gloves, which expands their range of applications. These characteristics make them ideal for applications that require high precision and reliability.
What features does the RS-232 interface offer for dot-matrix and graphic displays?
The RS-232 interface for dot-matrix and graphic displays enables serial data transmission, which is particularly advantageous when ports are unavailable or over long distances. It handles all initialization and line management for text displays, significantly reducing the programming effort. For dot-matrix LCDs with HD 44780, the interface offers various baud rate options and is equipped with a contrast potentiometer. The supply voltage can be flexibly selected between +5V and +9..35V. These features make the interface a versatile solution for integrating displays into complex systems.
