The most successful display family – Part 2:
5 good reasons why the industry uses this standard...

The GLYN TFT family concept was launched onto the market almost 10 years ago. It is the most successful display family with over half a million devices in use.

What is the secret of its success?

This family offers a solution for challenges faced by developers on a daily basis. Five of these solutions are listed below.

  1. Only one voltage
  2. Only one connector
  3. Compatibility within the family
  4. LEDs easy to dim
  5. Good availability

Only one voltage:

Displays require various voltages. Starting with 3.3 V for the logic to 20 V for the backlight, for example, as well as different negative voltages. An on-board voltage converter is the solution here. It enables the PCAP, display logic and background lighting to operate with a single voltage – without requiring a separate PCB. 

Only one connector:

This solution has various advantages. In purchasing and warehousing, only one article has to be managed. In production, it simplifies the process. The cost-effective 40-pin foil cable, which is identical throughout the entire TFT family, was selected for this solution. 

Compatibility within the family:

A standardised interface allows the 5.0” to be replaced with the 7.0”, for example, without the hardware or software needing to be modified. 

As a result, a low-end and high-end variant of the same product can be offered without significant cost. This compatibility allows for future product updates

LEDs easy to dim:

The quality LEDs can achieve a half-life of four and a half years when used nonstop. If the lighting is switched on for only 4 hours every day, the half-life is more than 25 years. The dimming function is particularly important for preserving the LEDs at high ambient temperatures. The TFT family therefore offers a separate pin for controlling the brightness using a PWM or analogue signals.

Availability and product life cycle: 

When the TFT family was developed, very low minimum order quantities was one major focus. Another objective was to reduce the standard lead time of 16-20 weeks to a few weeks or days. Customers and distributors have a say in the matter. After almost 10 years, all sizes are still available.


The advantages of this kind of family concept are obvious. Reliable products make it easier for Developing and Purchasing to plan projects, market launches and calculations more accurately. The development time decreases because documentation, demo kits, samples and accessories are immediately available.

The most successful display family – Part 1:
Over half a million devices in use

Displays with different interfaces and short product life cycles are a challenge for developers and buyers.

The solution – The GLYN TFT family concept.
With over half a million displays in use, it has progressed to a standard.

Nearly 10 years ago a success story began in Europe, which for the first time offered a solution to the above-mentioned challenges.

Thanks to the cooperation between manufacturers, distributors and industrial companies, there is a standardised TFT family with diagonal sizes from 3.5” to 7.0”. 

The most successful display family – Part 3:
Durable yet innovative – this is how it can be achieved!

Durability and reliability are esteemed virtues in the display business.

They make the life of buyers and developers much easier. Nobody wants to continually deal with the issue of discontinuations.

On the other hand, innovation is important. The market is changing and products are continuously improved. Developers want to ensure that their application is not overtaken by those of their competitors and market shares are lost.

How does the GLYN display family come off here?
