<PROJECTORS> editorial staff (050609) -------------------------------------------------------------------------------- ●● Epson/announcement ●● Epson announced new liquid crystal panel “C2 FINE” that on the 24th, high contrast conversion developed liquid crystal panel “crystal clear fine of possible new type (C2 FINE)”. Completely it is development of the transmitted type liquid crystal panel of new system, with the notion that where, epoch-making idea ones it is related to high picture quality conversion. 　But the former TN type transmitted type liquid crystal panel so with organic membrane ones, the contrast aspect, color unevenness (especially rubbing noise) with you did not look at the solution easily, but the new panel banishing those high picture quality drags from basis by the fact that the “inorganic membrane” is used is major feature. The hot polysilicon TFT liquid crystal panel itself does not change, but orientation unevenness did not occur in principle by changing the orientation membrane into inorganic type, that succeeded in also high contrast conversion and exile etc of the black floating making the picture quality of actualization and the liquid crystal projector the base raise substantially.

　The liquid crystal panel structure by the inorganic orientation membrane is shown in the figure. This way liquid crystal layer is put, to the fact that the orientation membrane of the function which arranges the direction of the liquid crystal is formed with inorganic type points. Until recently, with organic type calling the rubbing roll, it forms the membrane surface with the mechanical pushing type roll, but as for the latest inorganic type semiconductor process in the same way, forming a membrane at molecular level is an important point. Because of this, the mechanical roll becoming unnecessary, uniformity of the membrane surface increases rapidly, can cancel the thickness unevenness of liquid crystal layer. For example that even in the picture quality aspect it is connected to [yunihuomitei] becoming good. In a word when color unevenness and the brightness unevenness etc speaking so far awfully are gone at a stroke, upper quality it means to be able to obtain the picture. Just, it probably is epoch-making picture quality improvement step.

　 　Also direction of liquid crystal layer made vertical orientation type next. In other words no marry black conversion. Because this is the LCOS panel, but utilization it is already completed, it is the system where the black floating is settled and is useful to contrast improvement greatly. As for the contrast improvement effect of trial manufacture level former ratio 4~5 time and being substantial, at the time of the PTV set installation contrast 10000: Being able to achieve 1 it is when. This and it is epoch-making thing. By the way, liquid crystal drive including the image signal becomes VA type.

　Efficiency of the new panel of the trial manufacture stage the place where you answer with question and answer will be introduced. As for panel size wide 0.9 type, as for full HD type and numerical aperture 52% (former ratio it does not change that much), as for pixel pitch of that time 10 millimicrons. As for panel price being equal to the D5 series, as for the schedule which it makes high it is unless. Furthermore in panel generation expression you call to the “D5 series” schedule of inclusion. Because as for reply vis-a-vis the question whether it coexists with the conventional type panel, the panel is easier to take brightness until recently, [purezenmoderu] and the like uses there, as for latest C2 FINE, calls the schedule which is thrown to the foam/home theater model mainly.

In other words sale it does for a while. Time of use set commercialization, it plans 2006, PTV, it develops so is consecutively to the front projector. 　Well, at the announcement meeting place the panel item (the left) with doing the picture quality comparison of the new panel “C2 FINE” item until recently, you showed. As the right with the new panel item understood even with the photograph, it understands that black expression power and the contrast which are made clearly the brightness which is done secure are different largely. 　In any case, because of this it is certain for the future of the liquid crystal projector to have become bright. Furthermore high picture quality conversion can expect PTV and the front projector at a stroke. When that may expect also the appearance of the full hi-vision panel model greatly, sale becomes long in coming. <PROJECTORS> editorial staff (050526)
