Q: What are the benefits of a TFT display?
A: A TFT display delivers crisp text, vibrant color and an improved response time for visual applications at the best resolution of all the flat-panel techniques, but it is also the most expensive.

Q: What sets the TFT apart for other LCDs?
A: TFT displays use a separate tiny transistor for each pixel on the display. Because each transistor is so small, the amount of charge needed to control it is also small. This allows for very fast re-drawing of the display, as the image is re-painted or refreshed several times per second.

Q: What are the differences between TFT and Color STN?
A: TFT displays utilize active matrix technology and feature transistors on every pixel. Color STN (CSTN) is a passive matrix graphic LCD with a color filter. It only has one transistor per each pixel row and column and features a lower refresh rate than TFTs.

Q: What size TFTs does Microtips currently offer?
A: We currently offer a 2.4”, 2.8”, 3.5”, 4.3”, 5.7” and 7.0” TFT.

Q: How do I interface with a TFT?
A: 1st Pick a microprocessor with a built-in TFT controller (this will tell you which interface type to use)
2nd Determine which TFT size and interface type required
3rd Determine how the pins on the TFT should best connect to the corresponding pins on the your microprocessor
4th Connect the FFC from the TFT to a mating connector mounted on your board which is assigned to the TFT interface of the microprocessor
5th Write initialization code and software through your microprocessor to the TFT

Q: How does Microtips handle a fluctuating TFT supply chain?
A: Microtips utilizes strategic partnerships with our supply chain and focuses on standard TFT sizes (3.5”, 5.7”, and 7.0”).

Q: Who drives the TFT market?
A: The small TFT displays below 3.5” are typically driven by the large volume cell phone manufacturers in Asia. That being said the supply chain for TFT displays below 3.5” can be more volatile than the 3.5” and above sizes. The digital photo frame industry has also begun to affect the availability of the 7.0” and 5.7” sizes.
