商品描述
3M光學(xué)增亮膜片:
n此光學(xué)膜是在聚酯表面形成精密的丙烯樹脂棱鏡結(jié)構(gòu)。
n它把背光系統(tǒng)的光反射、折射，集光到使用者正面。
n用兩片棱鏡方向正交的BEF，可使亮度提高100%以上。
nBEF跟DBEF一起使用時，可以進一步增加亮度。
nDBEF是一種反射偏光片，通過選擇性反射背光系統(tǒng)的光，使其不被LCD的下偏光片所吸收，使LCD全視角的部分光得以重新利用。由此，使軸向亮度增加約60%n如果跟BEF組和起來，亮度增加將有更好的表現(xiàn)。
3M? Dual Brightness Enhancement Film
(DBEF) – QV2 w/ Optically Clear Adhesive
Description 3M DBEF-QV2 with adhesive film is a thin, multi-layer reflective polarizer designed to be
laminated to the rear polarizer of an LCD panel to maximize brightness while reducing the risk of warping at
higher temperatures. LCD panel efficiency is improved by reducing the amount of light normally absorbed by the
panel polarizer. 3M DBEF QV2 with adhesive allows one polarization of light to pass and reflects the other
reflected light is recycled in the backlight to boost display performance, increase end user viewing experience
by improving front of the screen performance, and reducing the energy required to drive the backlight.
Applications： 3M DBEF QV2 with adhesive is a multi-layer reflective polarizer optical film used to
maximize brightness of many different size liquid crystal displays (LCDs). When used in an LCD backlight,
DBEF improves brightness, contrast, and off axis color shift. Once laminated to the back of the LCD, it is o
of the brightest reflective polarizer film solutions and can be used for higher temperature display
applications. 3M DBEF film can be used alone or combined with other 3M? Display Enhancement Films for
even greater performance improvemen
