Electronic enthusiasts' news: Taking smart phones and tablet computers as always, the market trend of bare-handedness, shipments of touch screen modules have been rising all the way in recent years. According to the forecast of the market research institute, Tuoji Industry Research Institute, even if it does not include In-Cell integrated into TFT-LCD liquid crystal panels and On-Cell touch products of OLED panels, global shipments of touch screen modules in 2013 are more expected Up to 1.38 billion pieces, with an annual growth rate of about 15%.
In fact, under the current dual strong support of mobile phone wired / wireless charging complex environment, customers and the market have put forward higher requirements on the immunity of the touch screen module to noise immunity. Although On-cell and In-cell touch modules can meet the requirements for thin and light design of smart mobile devices such as high-end smart phones and tablet computers, they are easily interfered by external noise (especially mobile phone chargers), which affects the touch response speed and accuracy . Based on the urgent needs of the market, Cypress released a new generation of Gen5 TrueTouch controllers with the best high anti-noise immunity in the industry. This revolutionary touch IC helps enhance On-cell and The noise immunity of In-cell touch screen once again leads the global touch screen market.
Cypress TrueTouch product manager Jeff Erickson pointed out that it is not easy for manufacturers to meet the requirements of ultra-thin, low cost and anti-noise. And this question is very important for Gen5
Lectra wireless charging complex noise environment and invincible charger noise immunity
Low-cost, third-party manufactured, and non-original chargers will generate a lot of noise in the same mode, which will negatively affect the performance of the touch screen, resulting in inaccurate touch point reading or unreal touch. So, how to make the touch screens in mobile phones, cameras, GPS systems and other mobile systems work normally without interference from the charger connected to them? Cypress's TrueTouch product manager Jeff Erickson said that the touch screen of Cypress's Gen5 TrueTouch controller can work smoothly in extremely AC noise environments.
Charger noise is one of the most talked about noise sources in capacitive touch screen design. Cypress solves a common problem that mobile device manufacturers have been trying to solve. Low-cost chargers lack important noise suppression components and can generate tens of volts (peak-to-peak) noise in the range of 1Hz to 1MHz. When touching, these noise glitches can directly enter the touch screen and seriously affect the touch performance. In view of this, in order to improve the noise immunity of On-cell and In-cell touch module chargers, Cypress will mass-produce its latest Gen5 TrueTouch controller in the second quarter of this year to help smartphone manufacturers take into account the thin and light design. At the same time, it can also provide a touch experience with excellent performance, thereby winning the unique strong competitiveness in the market.
Compared with wired charging, wireless charging has higher noise, and it has higher requirements on the anti-noise ability of mobile phone capacitive screens.
As mobile phones have become thinner, noise from LCD screens has increased correspondingly. It is not easy for manufacturers to meet the requirements of ultra-thin, low cost and anti-noise at the same time. This issue is very important for Gen5.
In fact, only using Cypress's PureTouch technology can already suppress the noise level within the standard range, and Charger Armor can make Cypress exceed these standards, providing the market with a truly revolutionary charger noise suppression Ability, so that mobile devices can be used with the cheapest charger. Erickson emphasized that in addition to adopting a new analog front end (AFE), 32-bit Cortex-M series processor cores, the new solution strengthens the LCD screen scanning speed and noise protection capabilities; it also provides the industry's highest 40 volt peak voltage (Vpp), adaptive jump Frequency (AFH) function, can lock the charger noise frequency range of 1 ~ 500kHz, providing excellent charger noise immunity.
In fact, compared with wired charging, wireless charging has higher noise, and it has higher requirements on the anti-noise ability of mobile phone capacitive screens. Cypress's next-generation Gen5 TrueTouch controller has up to 40Vpp anti-noise capability, easily spike wireless charging noise! This is bound to promote the popularization of wireless charging market applications.
Unsurpassed waterproof experience, single chip includes self-inductance and mutual inductance capacitive sensing
TrueTouch is the only touch screen controller series that can provide self-inductance and mutual inductance capacitance sensing on the same chip, and these two methods in the application can realize dynamic switching. By combining self-inductance and mutual inductance capacitance measurement with differential signal analysis in the same device, various advanced functions and unparalleled performance can be provided in actual projects.
TrueTouch has an excellent unique waterproof ability, it also has the ability to recalibrate the instantaneous baseline, which means that there is water on the phone, then dry it and use it immediately, there will be no problem
Erickson said that TrueTouch has excellent and unique waterproof ability. The touch screen based on the TrueTouch solution is suitable for all kinds of "water" conditions, including rain, wet fingers (sweating, etc.), condensation and so on. It also has the ability to recalibrate the instantaneous baseline, which means that there is water on the phone, and then it is dried and used immediately, without problems. If instant calibration is not possible, the water on the mobile phone will be dried and then used immediately, it is likely to cause problems, and sometimes it may not even unlock or cause a crash.
What else should TrueTouch do next?
With the strong market coverage of Microsoft Windows 8 and Intel touch screen ultrabooks gradually spreading, and the follow-up of many personal PC equipment vendors, all kinds of touch screen booms will surely be launched in the future, and various large and medium-sized OGS and TOL touch technologies will also be launched. It is bound to rise. From the current point of view, Cypress's TrueTouch full range of solutions only includes 3.6 inches from Gen2 to 10.1 inches from Gen4_L. In the touch screen solution, how does Cypress consider planning to meet the future large touch screen solution Program? How to improve the oil resistance or weaken the influence of grease on the touch screen on the basis of extremely high water resistance? And so on, I think it should be the problem that Cypress should consider solving after Gen5 TrueTouch. As a result, we have reason to expect the next generation of Cypress Gen6.
