Plasma Tv Color Measurement Perspective The Latest Standards Issued

Plasma issued new standards to promote the development of the industry chain


2008 12 19, China Video Industry Association Professional Committee of the plasma in the "2008 Economic Operation of China Electronic Information Industry Bulletin & China TV Industry Annual Conference ", the release of" Plasma TV Receiver angle color measurement method, "the latest measurement standards, this is after following the standard dynamic definition, plasma Committee for" Color Perspective "released a new measurement method for research and industry experts as an indicator of plasma products, reference method for plasma TV To provide an objective reference standard clear.

This is the Joint Committee on Plasma professional authority Chinese Electronics Standardization Institute (formerly the Ministry of Information Industry 4), the original digital TV standard for TV color perspective on the degree of the standard is not complete, since the September 2007 start LCD and plasma testing in the color view in detail to form a more scientific, more comprehensive and realistic measurement method.

New measurement reference standards to provide clear and objective


"Plasma TV receiver color measurement perspective" provides a plasma TV receivers (including display) color angle measurement. "Perspective color" means, as the direction of the screen color display, the image of the color change with the viewing angle, when the color change led color = 0.015 when the angle of color perspective.

Order to facilitate consumer understanding of the practical significance of color perspective indicators, plasma Professional Committee of the Office Director Yang Xi Yang said: "We usually see moving bus LCD TV LCD advertising or elevator, do not feel gorgeous color screen fuzzy distortion, which is mainly due to the color LCD viewing angles are relatively poor result, consumers buy Flat Panel TV , It is necessary for the TV broadcast of the same store a picture from different angles the screen color changes color change is smaller, the higher performance of the color angle. "

Watching TV, viewing angle as the direction, images change color with the angle, causing a decline in overall image quality. And because of different imaging principle, LCD TV and plasma TV in color performance is a different perspective, through the measurement of contrast, plasma TV in the performance of the color angle than LCD TV.

Below shows plasma and LCD color view of the test, the general view that we determine the boundaries of color as u, v, 0.015, we can see, when the 0.015-based time, LCD TV viewing angle of 50 degrees so, when the viewing angle beyond 50 degrees, the LCD TV screen color will change the screen color obviously dim; while plasma TVs at 0.015 without intersection, the viewing angle beyond 85 degrees, plasma TV screen color is not changed The closer to the horizontal direction, this graph shows plasma levels of color television has a better perspective.

Plasma Experts believe that compared with LCD TV, plasma TV in color perspective on the advantages, its contrast, color reproduction than LCD TVs of all, its vision is more comfortable and more beneficial to eye health.

This measurement is that the "national standard digital TV" were added, the industry plays the role of standards and guidance is provided for consumers buying flat-panel TV reference. Therefore, China Video Industry Association, issued by the Committee of plasma color plate angle measurement methods designed to promote enterprise standard industry requirements, protect consumer interests and promote the healthy development of the plasma.
