Can I order any LCD with a touch panel?
Yes, it is possible to integrate a touch panel into any LCD technology. Resistive (RTP) and Capacitive(CTP) touch panels are standard for any TFT and kept in stock in AZ.
Touch panels are not standard on all other technologies such as: Character, Mono-graphic, Segment and UWVD, but can be added for a small tooling fee.
RTPs are the most popular touch panel for LCDs, TFTs notwithstanding, since they have a lower unit cost, lower tooling fee and are easier to integrate.
What is the difference between RTP and CTP?
Resistive Touch Panel:
- Single touch only, no pinch or scroll.
- Do not require a separate controller.
- Are pressure sensitive, that is, activated by any item/material such as a finger, pencil eraser or glove.
- Reduces the brightness of the display by an estimated 5%.
Capacitive Touch Panel:
- Allows multi touch to pinch and scroll.
- Only activated by something with an inductive load such as a finger or stylus.
- More expensive.
- Requires a separate controller.
- Does not reduce display brightness.
But what does the future of LCD touch panels hold? One new touch panel technology makes use of a capacitive sensor system with the ability to differentiate between users. It is possible to design and build a custom LCD integrated with a custom touch panel. Possible options would include size of touch screen, type of controller and anti-glare finishes. Meanwhile, it is estimated that touchscreen revenue will reach $16 billion in 2012, and nearly double in six years, reaching $31.9 billion by 2018. This figure is for touch panels used in all equipment,
Just say ‘no’ to long lead times: All our TFT and Character LCDs are in stock and can ship the same day.
