Title: Optical correlation processor
Inventor: KASAHARA KUMIO
IPC: G02F1/133
Filed: 1981-12-21
Abstract: PURPOSE:To realize a compact and light-weight structure for an optical correlation processor, by using a reflective or transmissive liquid crystal display panel which has an electrode for each picture element to a picture input element and an optical picture element converting element. CONSTITUTION:When the voltage is applied to an optional electrode of the XY direction in a reflective liquid crystal display panel 20, an MOS transistor is switched to charge a capacitor for storage which is formed between a reflecting electrode 17 and a semiconductor chip 15. Thus the difference of potential increase between the electrode 17 and a glass plate 12 containing a transparent electrode. Under such conditions, the linear polarized laser light is made incident from the side of the glass plate 12 and then reflected at the electrode 17. This reflected light is turned into an oval polarized light in response to the difference of potentials which are applied to a liquid crystal 13. Thus the laser light to which the intensity is modulated is obtained by extracting oly the polarization component rectangular to the polarizing direction. Therefore a coherent picture to which the intensity is modulated is obtained by controlling the quantity of the electric charge which is charged to the storing capacitor of each matrix array 14 in proportion to the picture signal.

Title: Inputting device with display
Inventor: OBAYASHI HITOSHI
IPC: G09G3/00
Filed: 1991-07-25
Abstract: PURPOSE:To attain the high precise signal processing of input information by temporarily stopping the sampling of input data from an input panel at the time of the generation of a high voltage pulse to a back light or the like attached to a display. CONSTITUTION:This device is equipped with a pulse voltage detecting circuit 8 which monitors a back light driving pulse BD outputted from an inverter 6, and transmits the output to a sampling stopping signal generating circuit 13 of a CPU 1 when the output level from the inverter 6 is more than a fixed value in order to allow the sampling stopping signal generating circuit 13 to output a sampling stopping signal SS. A gate circuit 15 supplies a sampling signal generated from a sampling signal generating circuit 14 to a sampling circuit 11 as a clock CLK, and while the signal SS from the sampling stopping signal generating circuit 13 is supplied, the clock CLK is not transmitted. Therefore, even when a noise intrudes into an input panel 2 or an input coordinate detecting circuit 3 by the back light driving pulse, the sampling of a signal affected by the noise is not operated.
