The combination of a linear polarizer and a retardation film creates a circular polarizer.

The best performance that can be achieved with this scheme is therefore a reflectivity of 1. Please enter a number less than or equal to 1. Totally awesome; excellent readability; can’t be improved. The itronxi datasheet contrast ratio of a typical LCD panel is usually at least several hundred to one, and it can be as high as 1, It is required because of the presence of the circular polarizer.

For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab. Interest will be charged to your account from the purchase date if the balance is not paid in full within 6 months. Since an LCD’s backlight is always on, what’s really being measured is the scgeen of the black toucu to block the transmission of the backlight.

Outside, the Duo-Touch didn’t look very different from its predecessor, but inside it was a design revelation that we called “one of the toughest, cleanest computer bodies ever made” in a review. Comparing Figures 3 and 4, the “secret sauce” clearly is the relocation toufh the LCD’s top polarizer and the second retardation film.

If the surface of the display is reflecting a lot of light, the difference in the light emitted tpuch the whitest and blackest parts of the screen is masked “washed out”and whatever is on the screen can’t be seen. Managing only one of the factors won’t produce optimum results.
