ABSTRACTLiquid crystal light valve(LCLV) using an a-Si:H/μc-Si:H heterostructure as the photosensor and the nematic liquid crystal as the modulator has been firstly presented for large screen projection display. The a-Si:H photoconductor and μc-Si:H light blocking layer were prepared by a modified glow discharge CVD method. The optoelectric and structure properties of the μc-Si:H films deposited at different deposition conditions have been studied. The a-Si:H film and the continuously deposited pc-Si:H film possibly form an a-Si:H/μc-Si:H heterojunction. The electrical and optoelectric properties of the heterojunction has been studied.LCLV using a-Si:H/μc-Si:H heterostructure has shown that the most aspects of the device performance can be improved.

Large Screen Projection

Does form discrimination rely on feature analysis, as the indirect theory of perception supposes, or on affordances (behavioural meanings specified by invariant patterns), as direct theory states. Subjects were to indicate the position of a target in a perspective rendering of a plane, displayed for 100 msec. in a large screen projection. In one of the conditions the target disrupted the plane, in the other it did not. Although targets of the two conditions shared the same features, the disruptive targets were discriminated more often than the nondisruptive targets. This result supports the direct approach to perception which states that a perceiver discriminates behaviourally relevant patterns rather than geometrical properties.
