Optoelectronics – backlights and displays

We offer a selection of optoelectronic components such as LC displays, TFT displays and backlights. Some of the components can be adapted to customer-specific requirements.
Displays in IPS technology (In Plane Switch) are also new. IPS displays provide a wide viewing angle of up to 160° and optimal color and contrast representation without reducing image quality.

multi-touch displays

We offer a wide range of standard TFT displays with and without touch functions for indoor and outdoor use.

  • Sizes between 0,96″ and 10,4″
  • The displays impress with their brightness, high contrast and short switching times.
  • Working temperature range -20° to +70° / storage temperature -30° to +80°
  • Backlights in different brightness levels from 250 - 1500 cd/m2 are available upon request.
  • We will be happy to send you the technical data sheets on request.
  • Please note the MOQ from 500 pieces (depending on the display).
  • We are happy to deliver your assembly solution with an individual membrane keyboard or the complete HMI solution

We can offer you any display!
If your desired display cannot be found in our product selection, simply send us an inquiry with the desired size and the required specifications. We will be happy to offer you the right display individually.

HMI assembly

If more complex menu navigation is required, the membrane keyboard can be supplemented with a touch display. The membrane keyboard as a keypad allows quick access to recurring input commands or preset parameters, the touch display with its graphic visualization options enables interactive communication. For a closed surface, the connection between the film and the display is realized through an integrated viewing window with a highly transparent adhesive layer. Depending on the requirements, these windows can be individually specified with a glossy, matt, anti-reflective, scratch-resistant, UV-resistant and colored finish. Even when the black display is switched off, the membrane keyboard takes on significant design aspects. For easy assembly, the input unit can be combined with a carrier plate.

We advise you in detail on the subject of HMI input solutions.

Membrane keyboard with display on front panel
Membrane keyboard with display on aluminum carrier plate

We offer a wide range of customer-specific LC displays in the standard technologies DSTN, FSTN and STN. Other technologies are possible on request.
Graphics can be both alphanumeric and graphical, using analog, digital, serial and synchronous 8-bit parallel interfaces.
We offer the following technologies for control: COB, COG, (on request also COF, TAB/TCP)

If your desired display cannot be found in our product selection, simply send us an inquiry with the desired size and the required specifications. We will be happy to offer you the right display individually.

Custom backlights
Custom backlights

For the backlighting of LC displays, we offer backlights or background lighting, which can be completely customized in size, shape and color according to customer specifications.


  • Sizes from 1″ – 100″
  • Luminous intensities from 1.500 - 15.000 cd/m² (depending on size)
  • Technologies: LED, EL CCFL
  • Dimmable versions

Advantages of backlights:

  • low power consumption
  • flat design of the devices
  • high contrast
  • long lifetime
  • Adjustment of the display brightness to the ambient light using dimmable variants

Resistive vs. Capacitive


Resistive touchscreen Capacitive touch screen
Functionality Resistive touchscreen Capacitive touch screen
  • Comparatively cheap
  • Resistant to dirt, dust and moisture
  • Can be operated with fingers, gloves and other objects
  • very high transparency and visibility, better readability in sunlight
  • Multi-touch effect: the screen can be operated with up to ten fingers at the same time
  • more resistant to liquids, chemicals and dirt and easy to clean
  • Vandal-proof versions are also possible thanks to various cover glasses
  • Softer surface is required for pressure release
  • lower light transmission and lower contrast
  • less resistant to chemicals
  • no multi-touch function possible
  • Can only be operated with fingers and specially conductive pins
  • A little more expensive
Application Especially in industry, where input must be possible with protective gloves. Point of sales terminals, building automation, medical technology Smartphones, tablet computers, organizers

Reflective displays

Reflective displays are used in environments with high levels of ambient light or in applications where there is not enough power to power the backlight.

Transflective displays

Transflective displays have the ability to work both reflectively and transmissively and have good viewing characteristics. Transflective displays can be viewed in direct sunlight and in low light when paired with a backlight.

Transmissive displays

Transmissive displays require backlighting and have the highest contrast in comparison. They are suitable for indoor applications where direct sunlight is not normally a problem.

IPS technology (In-Plane Switching)

IPS technology (in-plane switching) is similar in structure and function to TN technology and is based on a liquid crystal layer between two polarization filters.

In contrast to the TN technique, where the electrodes are rotated 90 degrees (TN= twisted nematic), the electrodes in the IPS technique are parallel to each other and aligned horizontally to the surface. When voltage is applied, they arrange themselves parallel to the field lines of the electrical field and are thus parallel to the substrate surfaces (in-plane). The distance to the eye does not change, the liquid crystals always remain in the same position, resulting in a viewing angle of almost 180°.

However, IPS panels require a stronger backlight, as the electrode for generating the voltage and rotating the liquid crystals has to be placed on the back, which reduces light transmission. The result is a slightly higher power consumption compared to TN technology. The IPS technology impresses with a very high color fastness and a very good contrast ratio. For example, black is much darker with IPS technology than with TN technology. In addition, they are very well suited for touch applications, since no bright spots or traces appear when touched.
