The key to reducing motion blur lies in decreasing the time the pixel stay illuminated. On liquid-crystal displays, this can be accomplished by strobing the backlight, whereas on OLEDs, this must be done by rapidly turning the pixels on and off, made possible by the fact that OLEDs have response times far shorter than those of LCDs.
Logo The Christie Mirage 5000, a 2001 DLP projector. Digital light processing (DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the ...
The mirrors can be individually rotated ±10-12°, to an on or off state. In the on state, light from the projector bulb is reflected into the lens making the pixel appear bright on the screen. In the off state, the light is directed elsewhere (usually onto a heatsink), making the pixel appear dark.
Digital Micromirror Devices (DMD) were invented by Texas Instruments in 1987 and are the core of the DLP technology used for video projection. The mirrors are arranged in a matrix and have two states, "on" or "off" (digital). In the on state, light from the projector bulb is reflected into the lens making the pixel appear bright on the screen.
UHP lamps used in projectors and RPTVs require periodic replacement, as they dim with use. The first wall-mountable RPTV was launched in 2003 by RCA. The first DLP 1080p RPTV was launched in 2005 by Mitsubishi. The first RPTV to use LEDs instead of an UHP lamp as its light source was released by Samsung in 2006.
Manufacturers of DLP-based cinema projectors can now also offer 4K upgrades to some of the more recent 2K models. [38] Early DLP Cinema projectors, which were deployed primarily in the United States, used limited 1280×1024 resolution or the equivalent of 1.3 MP (megapixels). Digital Projection Incorporated (DPI) designed and sold a few DLP ...
Some older LCD projectors have a more noticeable screen-door effect than first generation DLP projectors. [2] Newer DLP chip designs promise closer spacing of the mirror elements which would reduce this effect; [citation needed] however, some space is still required along one edge of the mirror to provide a control circuit pathway. Use of ...
The EDID PROM can often be read by the host PC even if the display itself is turned off. Many software packages can read and display the EDID information, such as read-edid [ 2 ] for Linux and DOS, PowerStrip [ 3 ] for Microsoft Windows and the X.Org Server for Linux and BSD unix .
