A suitable application of round TFT displays is the combination with encoders. Marelcom AG has in its assortment 3 different sizes.

The unit is a closed solution that perfectly combines the display, the encoder, the button and the status LED in one rotary knob display. The unique innovative structure and exquisite manufacturing process of the module ensure excellent reliability and control experience. The unit is suitable as a rotary knob control in many industrial applications of electronic products.

Possible sizes:

1.3" IPS TFT with push switch, integrated encoder and LED indicator

2.1" IPS TFT with push switch, integrated encoder and LED indicator

2.5" IPS TFT with push-switch, integrated encoder and LED indicator

All 3 units are built the same way and have the same interface. The IPS TFT is controlled via a serial interface. For the status LED a RGB LED illumination was chosen. The color of the status LED illumination can be chosen freely. Encoder, push switch and LED illumination are controlled separately. The complete unit is connected via a 10 pin standard FPC connector with a pitch of 0.5 mm, no matter which unit you choose.

Optionally the unit can be equipped with a capacitive touch.

Disappearing Effect for TFT Displays

An elegant glass surface for TFT units whether the display is turned on or off!

The cover lens is usually fully connected to the capacitive touch sensor with a transparent OCA. Depending on the type of display and the polariser used, the TFT active area remains visible when it’s switched off. Dark bonding is used to eliminate this effect and achieve an elegant surface even when switched off, meaning the TFT active area is no longer visible.

There are countless applications where germ-free surfaces make everyday life easier. Be it in medicine, the food industry, retail, public buildings, and even in clothing. Glass benefits from the same antibacterial effect. Displays and capacitive touch panels can now be built with an antibacterial front glass that fulfill hygiene regulations. It’s a glass that has additional bacteriostatic and sterilizing functions, while preserving the original functions and properties of the glass. Marelcom offers the possibility of producing front glasses with an antibacterial coating.

Silver is proven to be effective against bacteria. Positively charged silver ions absorb negatively charged bacteria, thereby disturbing the bacterial charge balance. Silver ions easily enter the bacteria and stop the respiration and reproduction of bacteria. They inhibit the growth, quickly combining the proteases of bacteria to destroy them, making bacteria inactive.

The coating process of antibacterial glass is relatively simple. The coating can be applied to a wide variety of materials. When it comes to glass, type, thickness, length, and width don’t make a difference.

Antibacterial glass can be chemically or physically toughened, and the tempering performance is the same as the standard value of non-antibacterial glass. The subsequent application of AF allows the double function of antibacterial and anti-fingerprint on the glass surface, whereby the functions are not mutually disadvantageous.

A combination of anti-reflection glass or anti-glare glass is also possible.
