Cypress Semiconductor has announced that its TrueTouch® Gen4 series touch screen controllers now have a variety of advanced features, including the world's best gloved finger tracking on capacitive touch screens. Even wearing very thick gloves, Gen4 can achieve precise touch screen navigation, which greatly facilitates users who use smart phones and other portable electronic products.
The Gen4 series can also provide some new functions, such as passive stylus support that can accurately recognize handwriting and signatures; and the proximity detection function that can turn off the screen to avoid accidental touch when an object approaches the touch screen. This capacitive proximity sensing function can eliminate the infrared sensor, thereby significantly reducing costs. These advanced features complement the Gen4 with the best waterproof capability in the industry and can work smoothly in noisy environments.
The Gen4 TMA467 can track up to ten fingers wearing thin gloves and two fingers wearing thick gloves (such as those worn by skiers). For gloves of different materials and thicknesses, Gen4 can provide the industry's best accuracy and linearity. Without any intervention, it can automatically switch between wearing and not wearing gloves. You can watch a video about this feature at the following URL:.
John Carey, senior marketing director of Cypress TrueTouch, said: "These advanced features provide customers with a better user experience for their end products. For a long time, customers have been plagued by various complaints. For example, skiers on mountain slopes hope not to pick You can use the phone without gloves. With Gen4's unique technology, the problem is solved. "
The Gen4 TMA468 controller can support a passive stylus with a tip of only 2 mm, allowing the touch screen to recognize 7 mm-sized handwritten fonts. This is an important feature, especially for text that requires enhanced recognition technology to achieve reliable handwriting input, such as Chinese and Japanese. The controller can provide very high accuracy and linearity, while having the extremely fast refresh rate required for handwriting and signature recognition.
The Gen4 TMA466 controller has a proximity sensing function, which can detect objects such as the user's face within a maximum distance of 25 mm, thereby suspending the touch detection function to prevent the user from making a false action when the face touches the touch screen when making a call. At the same time, it also informs the main processor to turn off the display screen in order to save power and extend battery life. With this feature, there is no need to use a separate infrared proximity sensor, thereby reducing system cost.
Gen4 has a series of unmatched technologies for competitive solutions. It uses Cypress's patented technology to realize self-capacitance and mutual capacitance sensing on the same device, and can dynamically switch the two during use. Because of this ability, Gen4 can support glove tracking, stylus support, face detection, and TrueTouch's unmatched waterproof function.
Gen4 is the only touch chip series in the world that uses a built-in 10V transceiver to drive a touch screen. Since the signal-to-noise ratio (SNR) is directly proportional to the drive voltage of the touch screen, this technology can help Gen4 detect smaller signals than competitors in a high-noise environment, thereby maintaining stable performance. Gen4 can support a touch screen up to 6 inches, can be used in smart phones, super phones, digital cameras and media players, can also support e-readers and tablets up to 10.1 inches.
