21ic News Cypress Semiconductor Corporation has announced that China's high-end smartphone brand vivo uses TrueTouch® capacitive touch screen controllers in its next-generation vivo Y29 smartphone. Cypress's TMA545 controller provides an easy-to-awake alphabetic gesture that allows users to easily wake up the screen from sleep mode and open a common application by simply writing a letter on the screen with their fingers. For example, by writing the letter "C" on the screen, you can wake up the phone and turn on the camera.

The touchscreen powered by TrueTouch complements the world-class features of the vivo Y29 smartphone. The machine is equipped with a 13 megapixel camera, which is ideal for shooting in low light. The machine also has Hi-Fi sound for pure music playback. The TrueTouch controller brings the most accurate glove touch performance and the most powerful water resistance on the market, while also providing an ultra-thin design and long battery life.
Joe Montalbo, vice president of Cypress's TrueTouch business unit, said: "The vivo Y29 once again proves that TrueTouch can provide industry-leading features and reliability for the highest-end smartphones. China has the world's largest smartphone market, and vivo has become The recognized leading brand in the market. The design we have won is in line with our strategy to help our customers launch differentiated products to compete in the market."
Electronic noise generated by the screen and non-original chargers may interfere with the normal operation of the touch screen. Cypress's ChargerArmorTM feature delivers up to 40 in the range of 1 to 500 kHz in the most demanding conditions of 0.5 mm ultra-thin cladding (Cover Lens) and 22 mm fingers for all touchscreen controller performance The volt peak peak voltage (Vpp) is unprecedented in resistance to charger noise, while other controllers do not provide over 15 Vpp of noise immunity under the same conditions.
TrueTouch uses Cypress's patented DualSenseTM technology to perform self-capacitance and mutual-capacitance sensing on the same device, providing the industry's best water resistance and wet finger tracking capabilities in a variety of real-world environments (including The condition of rain, fog or sweat) works seamlessly. Combined with this powerful architecture and the industry's leading 32-bit ARM® Cortex® M-Core processor, known for its high efficiency MIPS/mW, the TrueTouch controller increases the refresh rate to 120Hz and maintains low power consumption. The controller can drive the touch screen with 10V, high-frequency narrow-band single-pass scanning and advanced hardware DSP filtering.
