IC market into the touch-screen battleground

In Electronic Infomation Category: R | on May   2, 2011

Touch screen technology is already developed for some time, but they have been attractive to Apple introduced the iPhone touch screen features before re-energized; Apple iPhone also developed a proprietary touch screen ASIC. IC market prospects are optimistic about the touch screen, a number of chip suppliers fought attempts to cut or expand the territory of this technology, but I am afraid that this new market will be more competitive, and ATMEGA128L-8AI datasheet and very sensitive.

According to market researcher Gartner, capacitive touch screen and ATMEGA128L-8AI price and touch keypad controller market will reach 1.3 billion by 2012 shipments of the scale, the annual compound growth rate of 44%. "Give thanks to the iPhone wave, capacitive touch screen mobile phones fast becoming a common feature;" Gartner analyst AmyLeong predicted: "touch screen technology will be the next big opportunity in the PC applications."

The market is not perfect touch technology

"In the past, capacitive touch technology has been widely used in notebook computer touch pad, and ATMEGA128L-8AI suppliers and now the main area of the technology to manufacturers of touch screen, touch-sensitive buttons close / slide bar ( sliders), and the multi-touch mouse board (multi-touchmousepads) and other forms, the introduction of PC and PC peripherals. "Leong said. PC applications that touch the field in the key driving force for that? She believes that one of the key driving force is the upcoming operating system, Microsoft Windows7, because it is the first multi-touch function to do the best of the operating system.

In addition there are a variety of touch screen technology, including the resistance (resistive), capacitive (capacitive), surface acoustic wave (surfaceacousticwave), infrared, etc. ... ... Leong said there was no touch technique which is perfect, currently used in the PC market, a variety of touch technology, but also has no obvious winners; but capacitive touch technology for early adopters is clearly the more mature one.

Capacitive touch screen, but the cost has increased with increasing screen size trends; to mainstream 15-inch notebook screen around, the capacitive touch screen is the cost of the existing standard screen more than 3 times. Capacitive touch screen, the noble worth, given other competing technology opportunities, such as multi-resistive touch technology, and optical technologies.

Supplier of touch screen technology energetic

To manufacturers, the existing chip suppliers, including touch screen, Atmel, Broadcom, Cypress, Microchip, Renesas, Synaptics, and so, the atmosphere is very warm ─ ─ Last year, Atmel announced the acquisition of capacitive sensing technology, IP cum User interface solutions supplier QuantumResearch; next Microchip also announced the acquisition of common software and hardware solutions touch screen control gas supplier Hampshire.

March this year, Renesas announced the joint development with the Omron capacitive touch sensor technology, Renesas and the Omron touch sensor technology into industrial and consumer applications in the R8C series of 16-bit micro-controller. In May this year, Atmel released integrated capacitive touch screen technology maXTouch, the technology combines with its AVR family of microcontrollers, known to provide rapid response, high accuracy touch screen performance.

June, Synaptics also published touchpad called ClickPad solutions for consumers and business users in smaller notebook computers (especially Netbook), providing a broader range of multi-finger control function. In addition, IDT also announced that through the acquisition of Leadis touch sensor technology sector, is rammed into the market.
