Filed: 1986-04-28
Abstract: PURPOSE:To eliminate a flicker on a screen, to prevent crosstalk from occurring, and to facilitate interlacing by driving a projection type color display device while matrix type display panels for even and odd fields are inverted in phase. CONSTITUTION:A video signal VIDEO is so modulated to alternate in constant cycles which each correspond to one frame of the NTSC system of television, and a signal GS for even fields and signals KS for odd fields which are applied to light valves are converted in opposite phase relation. A sample holding signal SA samples video data in a sample holding time DELTAt while one field which is a half one frame is set to a constant period and holds the data with the time constant of liquid crystal. The held signal becomes a voltage VGS applied to the liquid crystal of an even light valve and a voltage VKS applied to the liquid crystal of an add light valve and they are in opposite phase relation between those valves. Consequently, a flicker is eliminated and the picture quality is improved.

Abstract: PURPOSE: To recover errors without affecting the other part of a system even when the error is generated by stopping a unit to be affected by the operation of a certain unit by conditional clocks corresponding to the detection of the erroneous operation of the unit. CONSTITUTION: When the plural modules 32 of a card 30 are connected to a card error checking and gathering(CECL) element 33, the CECL element 33 performs transmission to a card level detection/recording(CLDR) circuit 35 and the CLDR circuit 35 classifies the error as a level 1(L1), the level 2(L2) or the level 3(L3). A level classification signal L1 is sent in a forward direction through a card error communication gathering circuit (CCOM, COLL) 36, however, a signal L2 is returned to a gate clock generation circuit (CKGEN) 37 and the CKGEN circuit 37 stops the supply of clock signals to the modules. Thus, even when the error is generated, the error is recovered without affecting the other part of the system.
