Liquid-crystal display having the capability of a tablet
Hiroshi Murakami,Masafumi Itokazu,Kenichi Nakabayashi,Kazuhiro Takahara,Michiya Oura,Masami Oda +5 more
TL;DR: In this paper, an active matrix type liquid-crystal display composed of a device substrate having a plurality of scan electrodes, an opposed substrate holding a liquid crystal in cooperation with the device substrate, and a voltage detector that detects pulses, which are applied consecutively to the scan electrodes and data electrodes, through electrostatic coupling between the detector and the scans or between the detectors and the data electrodes.

Active-matrix liquid crystal display and method of driving same
Hiroshi Murakami,Koji Yoshioka,Keizo Morita,Masafumi Itokazu,Kenichi Nakabayashi,Akira Yamamoto,Haraguchi Munehiro +6 more
TL;DR: In this article, an active-matrix LCD (AML) was proposed, which has data lines arranged in parallel with one another, scan lines arranged orthogonally to the data lines, and liquid crystal cells arranged at the intersections of the data and scan lines.

Bitline GND sensing technique for low-voltage operation FeRAM
S. Kawashima,Endo Toru,Akira Yamamoto,Kenichi Nakabayashi,Mitsuharu Nakazawa,Keizo Morita,M. Aoki +6 more
TL;DR: In this article, pMOS charge transfer maintains the bitline level near the GND when the plate line goes high, which gives 0.5-V higher readout voltages across the cell capacitors.
Patent
Driving circuit for liquid-crystal display device
TL;DR: In this paper, a shift register for outputting n control signals driving n signal lines coupled to display elements of the liquid-crystal display device where n is an integer, is cascaded.
Patent
Drive circuit for liquid-crystal displays and liquid-crystal display including drive circuits
TL;DR: In this article, a liquid-crystal drive circuit with an auxiliary capacitor is described, which is a simple configuration and being not susceptible to the characteristic of a device, and applies a first voltage to a driving buffer, temporarily accumulates an output voltage of the driving buffer in the auxiliary capacitor, and then applies a voltage produced by subtracting the potential at the auxiliary capacitance from a second voltage to the buffer.
