TFT Family Concept
A unique TFT family has been created through a collaboration between European industrial customers, GLYN and the Taiwanese display specialist EDT. With one million units in the field (as of the end of 2019), this family has become a standard.
- 3.5" to 7.0"
- TTL (RGB) interface
- Only one connector for display, backlight and touch
- Only one voltage
- Easy dimming of the LEDs
- Compatibility within the family
- Optional PCAP or analogue resistive touch
- Optional decorative screen with optical bonding
Only one voltage
Displays require various voltages. Starting with 3.3 V for the logic up to, for example, 20 V for the backlight. In addition, there are various negative voltages. An onboard voltage converter is the solution here. This way, PCAP, display logic and backlight can be operated with only one voltage and without a separate board.
Only one connector
This has various advantages. In purchasing and warehousing, only one item needs to be maintained. In production, it simplifies the process. Here, the decision was made to use the cost-effective 40-pole foil cable, which is identical for the entire TFT family.
Compatibility within the family
Thanks to the uniform interface, the 5.0" can be exchanged with the 7.0", for example, without making any hardware or software changes. This makes it possible to offer a low-end and high-end version of the same product without much effort. In addition, the option for future product updates is kept open.
Easy dimming of the LEDs
Thanks to high-quality LEDs, half-lives of four and a half years can be achieved in continuous operation. If the lighting is switched on for only four hours a day, a half-life of over 25 years is achieved. The dimming function is particularly important to protect the LEDs at high ambient temperatures. For this reason, the TFT family offers a separate pin via which the brightness can be controlled with a PWM or analogue.
