We have developed a transmissive and reflective LCD that integrates electromagnetic resonance (EMR) and capacitive touch sensors using existing in-cell process. This development has been achieved by utilizing our hybrid-in-cell technology with low resistance material for the RX, which is an improvement of over 80% compared with conventional indium thin oxide (ITO) material. For EMR detection, we have slightly modified the TX layer used for capacitive touch sensing, by making a coil loop that generates a magnetic field on the panel. The direction of current on the coil can be modulated by the lowtemperature polycrystalline silicon (LTPS) circuit. Our in-cell touch sensing has separately assigned timings for display and touch units. This timesharing method provides immunity from display noise and consequently better signal-to-noise ratio (SNR) than other out-cell types. In parallel, we have developed a new controller that can support both EMR and capacitive sensing as a one-chip solution, with the capability of maximizing signal levels lowering noise and detecting the frequency precisely when there is pressure on the pen tip. Our in-cell technologies contribute not only a good SNR for EMR pen but also the added benefits for thin design, lightweight panel, compared with conventional LCD techniques.

A newly developed large two-pad journal bearing with cooling ditches and viscous pump for turbines of electric utilities was analyzed theoretically. The turbulent thermohydrodynamic lubrication analysis was done in connection with the flow analysis of oil circulating system through the cooling ditches and the viscous pump. The complicated simultaneous equations concerned with the oil flow in the bearing were solved and used to design a bearing of 535 mm diameter which will make its appearance in a near future. Full size bearing tests were carried out to check the bearing performance and viscous pump performance and to confirm the accuracy of the calculation method. Good agreement was obtained between the theoretical and experimental results.
