South Korea based semiconductor company Dongbu HiTek developed Capacitive Touch Controller IC for smart phones, where smart phone apps can be accessed and controlled via simple touch gestures while the smart phone is in the standby (screen-off) mode, thus streamlining apps access, control and extending battery life.
Dongbu HiTek’s new semiconductor chip design allows users to rapidly access/control frequently used apps during standby with a simple touch gesture – such as drawing a circle, letter, line or other figure on the darkened screen.
Apps such as music player can be accessed via a touch gesture during standby without activating the screen. Moreover, other touch gestures on the darkened screen can be used to control various audio-only functions such as volume control or selecting the next track.
Dongbu HiTek’s new chip design also includes a “Double Tap Wake Up” function that activates the screen by tapping it two times as well as a “Glove Touch” function that recognizes touch gestures while wearing gloves – even wet kitchen gloves worn while washing dishes. In implementing the “Glove Touch” function, Dongbu HiTek technologists optimized touch sensitivity so that deliberate touch gestures could be consistently distinguished from random drops of water.
