The enhanced Reduced Voltage Differential Signaling (eRVDS) is a new intra-panel interface with clock embedded scheme forChip-On-Glass TFT-LCD panel. The source driver IC with eRVDS interface operates at higher data rate up to 720Mbps, lower power consumption, and lower EMI and reduces signal line to one third compared to conventional point-to-point COG interface.

A characteristic analysis of an ultrasonic motor (USM) at the design stage has thus far been impossible. Therefore, a characteristic analysis method is suggested on the basis of a proposed model describing the complex nonlinear contact condition between the rotor and stator. The proposed contact model and analysis method can guide theoretical research on the minimization of the main disadvantages of the USM, which mainly result from the contact mechanism. The validity and usefulness of the suggested analysis method is verified by experimental data from a prototyped USM.

Reduced Voltage Differential Signaling (RVDS) is a new interface for TFT‐LCD panel with Chip‐On‐Glass (COG) structure which has point‐to‐point topology and voltage mode differential signaling scheme. The display source driver IC with RVDS interface performs higher data rate up to 500Mbps, lower current consumption of 2.2mA, and lower EMI compared with conventional current mode interface.
