Cypress Semiconductor announced that Fujitsu Limited has adopted Cypress's TrueTouch Gen4 touch screen solution to create a touch screen interface for the new Arrows V F-04E smartphone launched by NTT DOCOMO Telecom. The new mobile phone uses the Android operating system and supports 4G LTE network. Through the signal-to-noise ratio (SNR) of the Gen4 solution, the mobile phone can have extremely fast response speed and accurate multi-touch in any operating environment. efficacy.
Fujitsu Arrows V F-04E is equipped with a quad-core processor and 2GB RAM, which can process information on 4G LTE network at 100Mbps. Its mobile phone is equipped with a 4.7-inch HD screen and Gen4 controller, which can accurately track the touch position of 10 fingers. In addition, the TrueTouch solution also provides Charger Armor function, so that the mobile phone can operate normally beside the charger that releases a lot of interference noise. Gen4 series components also provide many TrueTouch-specific functions, such as built-in waterproof, so that the product does not need to use additional sealant or shield to meet the IP-67 waterproof standard.
The newly developed Gen4 series can provide better signal-to-noise ratio (SNR) in various real-world applications. The Gen4 touch controller provides 10 volt Tx transmission function, and Cypress's patented Tx-Boost multi-phase (mulTI-phase) Tx solution, bringing the highest in-applicaTIon signal-to-noise ratio. Coupled with TrueTouch's exclusive Charger Armor noise reduction technology and screen noise offset algorithm, Gen4 still provides high performance in a noisy environment.
In addition, Gen4 also provides many value-added functions, including built-in waterproof function, and supports a variety of integrated screen design, can accurately input touch commands and track finger position in the presence of raindrops, moisture condensation or sweat.
Cypress's TrueTouch solution provides the most comprehensive features, including support for true single-layer sensing, waterproof function, 1 mm passive stylus, floating touch, and when the phone is near a charger that emits a lot of noise, Charger Armor function can also work normally. In addition, TrueTouch devices provide Cypress's noise immunity and patented capacitor sensing technology to operate correctly in noisy RF and LCD environments.
