It is possible with care. But it is important to be aware that the LCDs contain linear polarizers and the polarising element of the circular polarizer must be correctly aligned with the polarizer of the LCD to avoid colour distortion.

If you use a standard linear polarizer with cameras that use auto-focus and/or auto-exposure, you may have problems. This filter may also cause trouble with manual cameras, if you're using TTL light measurement. A little dependent on the camera, your meter might go crazy. (It is not said you will get problems, only that you might get them. See similar questions...

It depends on the camera you're using if you need a circular polarizer or not. Most autofocus cameras have a semi-silvered mirror, and this can cause a significant difference in the amount of light reaching the photocell when using a linear or circular polarizer. Most of the manual- only cameras have their photocell in the prism, and they will not see the difference between linear and circular polarizers. See similar questions...

Circular polarizers are efficient contrast enhancement filters and improve the sunlight readability. Ambient light passing through a circular polarizer is transformed to a polarised circular motion which when reflected from the surface of the display is rotated through 90?and can no longer pass back through the filter as the polarisation of the reflected light is out of phase with the polarising filter. The effect of this is that the background to the display appears dark blue or black . See similar questions...

LCD is short for liquid crystal display, and while LCD technology has been around for quite some time, it has been only in the last decade or so that the technology became suitable for the high quality flat panel television and computer monitor displays we see today. The most notable feature of displays using LCD technology, of course, is the thinness of the unit, but the power behind that thin design is actually quite extensive. See similar questions...

A Circular Polarizer is for all cameras, especially still cameras with autofocus or cameras with "Beam Splitting " metering systems. The circular works just like a linear, except it doesn't adversely affect the function of these systems. Which filter should I use if I want to take available light pictures in a room that is lighted only by household tungsten light bulbs. If you have daylight balanced film in your camera, you want to use the 80A filter. See similar questions...

If you are projecting a presentation, such as Powerpoint, that incorporates large fonts and bright colours, LCD may look better. If you are showing small fonts, more detailed or higher contrast images (or you are looking for an ultra lightweight projector), DLP may be preferable. If video is your application, look carefully at both; you will find a range of video quality in both DLP and LCD projectors. See similar questions...

Yes, but please try to keep the cable length <20cm as the signal terminations are susceptable to reflections. Above this distance, you will need to insert some extra circuitry to reduce the signal reflections (Many thanks to Tino). See similar questions...

Light which reflects off any surface is polarised to some extent. The degree of polarisation is related to the angle of incidence of light and the refractive indices of the two materials. At a certain angle known as Brewsters angle, light is 100% polarised. At other angles of incidence the light is partly polarised. n' is the refractive index of the material giving off the reflection (eg glass, water). n is the refractive index of the material through which the light is incident (eg air).

If the display from your laptop does not come up on the LCD projector there are a few things to check: middot; Check to be sure the projector is turned on & you have the correct input selected on the projector. (usually computer 1 or data1) middot; Does your screen resolution match the capabilities of the LCD projector? If not, you will need to reduce your screen resolution to the capabilities of the projector. 800x600 for SVGA, 1024x768 for XGA. See similar questions...

Yes you can. Netpresenter is the only program that allows digital signage playback on TV/Plasma/LCD screens, with the TV Player, as well as on Desktops PC's using Screensaver and (Pop-up) Player. See similar questions...

Yes. The navigation concept is designed so that the driver is not forced to look at the display. Instructions via the loudspeakers inform the driver in detail about the current route, without unnecessary distraction. See similar questions...

The player will support all PARALLEL 122x32 graphical LCD modules which use a Epson-compatible SED1520 controller, and a 20-way single-in-line connector. It is recommended to also use a module with a LED backlight. Please contact me if you are unsure if a particular module will work. See similar questions...

Just send it serially at the appropriate baud rate. If you send the string "Hello" to the Backpack, "Hello" appears on the LCD. See similar questions...

Ensure that the temperature probe is connected. NB If the temperature probe is not connected to the terminal block connector (J2) the temperature reading should be 0.0. Until the dedicated phone has been detected as on-line and the configuration has been acquired, the polarity of the float switch triggered state is unknown. See similar questions...

Moisten the LCD by breathing lightly on it. Wipe the LCD gently with a soft, lint-free cloth or an untreated lens tissue. If further cleaning is needed, dampen a soft, lint-free cloth with a small amount of a cleaner such as KODAK Lens Cleaner, available from retailers of KODAK Products. Apply light pressure to the surface of the LCD display to remove dirt and skin oils. See similar questions...
