The facial ministry of screen of consumer focusing smartphone identifies a function, also expect new generation ultrasonic the dactylogram below screen identifies a technology, but the expert says, show the dactylogram below level screen to identify a system to be done only in organic glow diode (OLED) face plate, the function just can be developed.
Company of international data information (Xu Meiwen of director of IDC) senior research is analysed, the dactylogram below current ultrasonic screen identifies a technology to be able to be done only in OLED face plate, cannot do however in liquid crystal face plate (LCD) advocate because OLED face plate is initiative smooth, do not need to be in a poor light modular group, but of LCD face plate be in a poor light modular group is potential however block breaks the dactylogram below ultrasonic screen to identify systematic function.
Xu Meiwen says, the big plant of brand of main mobile phone that rolls out the dactylogram below screen to identify a function of purpose, lock up calm OLED face plate, because value,do not need to be in a poor light namely modular group, can make sound wave successful penetrate. The dactylogram below ultrasonic screen identifies systematic initial stage to will be given priority to with area identifying, demarcate does dactylogram identifying in the fraction area of mobile phone screen, but the product that still is expected finally to roll out full screen to all can identify dactylogram.
She points out, taiwan basically shows thrust of face plate factory confuses your glow diode (MiniLED) face plate, long to be able to contend with OLED face plate, but still need to be in a poor light because of MiniLED face plate modular group, to ultrasonic penetrating is an obstacle, be afraid also is not the alternative of embarking face plate that the dactylogram below ultrasonic screen identifies a system to develop.
She thinks, the small glow diode after afterwards MiniLED (MicroLED) face plate does not need to be in a poor light modular group, will be one of face plate alternatives that the dactylogram below ultrasonic screen identifies a system to embark, but MiniLED technology is still immature, show level to only OLED face plate suits to carry this function.
