D-ILA method D-ILA multimedia projector? D-ILA Method Present Condition and Subject The “D-ILA method” is a method of picture projection that uses JVC’s original “D-ILA device”. Based on JVC‘s ILA ® projector which has more than a 40% share of D-ILA eliminates the trade-off between the high brightness the professional large-screen projector market, the “D-ILA device”... -

● For installation, consult your dealer. JVC is not responsible for any damages or injuries that may result from improper or faulty • The throw distance is from the end of the lens to the screen’s lower edge. -
Page 10: Throw Distance
Rough throw distance = screen width lens value Since the DLA-G20 incorporates a zoom lens, throw distance and projection screen size can be adjusted. Indications marked on the projection lens (such as 3:1) represent the “projection ratio”, that is, “throw distance: screen width”. When the screen width is “1”, the throw distance is ”3”. -

(Nevertheless, even with the D-ILA Horizontal side-by-side placement of two DLA-M4000s is a screen. - Page 15 However, the absolute value for the gain at all angles is Recurrence means that the light reflects in the polarized light (JVC Fine Screen Pro) Is the fine beads screen the same as the beads type? higher in many cases. Therefore, it is risky to select a same direction as the angle of incidence.

(Refer to the table on page 10.) screen, most of the light is reflected because the light from projector or the DLA-G20/15 is used with another brand of screen, be sure to check the polarized light screen effect. the DLA-G20 consists mainly of vertical components. - Page 17 Projection type (rear projection) Range of adequate view Basic facts about reflecting mirrors The range of adequate view generally depends on the “viewing angle”. The rear screen for the JVC DB-70S10 data box is Mirror maximum available size is relatively small. Nevertheless, shown as an example.
