requires skilled convergence calibration and adjustments for geographic location changes. [46] Glass display tube is evacuated and carries risk of implosion if improperly handled. May be risky and expensive to repair due to complexity of the display; [ 47 ] units with mercury CCFL backlight lamps are an environmental health hazard [ 48 ]
A thinner and lighter LCD or DLP projection TV in a home cinema. A projection television uses a projector to create a small image or video from a video signal and magnify this image onto a viewable screen. The projector uses a bright beam of light and a lens system to project the image to a much larger size.

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 aim of color calibration is to measure and/or adjust the color response of a device (input or output) to a known state. [1] In International Color Consortium (ICC) terms, this is the basis for an additional color characterization of the device and later profiling. [ 2 ]
Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.
Coretronic System Engineering was established to provide integrated imaging system products and services in 2010. Also, Coretronic Culture and Arts Foundation (CCAF) was founded, and Coretronics joint ventured with Japan's Gunze Limited to establish YLG Optotech Limited to manufacture capacitive touch panels. 2011 saw Coretronic Venture Capital ...
The YIQ system is intended to take advantage of human color-response characteristics. The eye is more sensitive to changes in the orange-blue (I) range than in the purple-green range (Q)—therefore less bandwidth is required for Q than for I. Broadcast NTSC limits I to 1.3 MHz and Q to 0.4 MHz. I and Q are frequency interleaved into the 4 MHz ...
