subject: Dynamic Images Of Plasma Technology Leader In Power Need To Solve The Problem [print this page] With the 2008 Beijing Olympics The success of the host, Beijing, digital terrestrial
TV High-definition broadcast signals, "Dynamic image definition plasma measurement," Association of the standard release and
Changhong plasma Screen production line smoothly, in 2008, plasma digital television industry a comprehensive pick up signs of welcome. Due to technical differences in principle, PDP (plasma) display technology than LCD (liquid crystal) display moving images with better clarity. And as technology advances, LCD and PDP are using newer technology to improve the dynamic image effect, has made great progress.
Plasma with a better dynamic resolution
In the cathode ray tube ( CRT ) Television, due to the CRT phosphor response time is usually less than 1ms for CRT TV, its response time is usually no problem. CRT TV with a viewing audience can enjoy the moving images and still images obtained results similar definition, which is still basically the same clarity and dynamic clarity.
Flat-panel TV Moving images in the display image quality when down, was first discovered in the research PDP TV, because the PDP into the video field earlier than the LCD, PDP and LCD TVs, but this phenomenon exists. Moving image blur caused by three main reasons: first, a short response time is not enough; second, the human eye's own vision to stay; third, video optimization technology.
2008 1 started at the end, the state of digital audio and video and multimedia product Quality Supervision and Inspection Centre (Ministry of Industry and Information Technology digital TV standards compliance testing center) to more than 20 types of samples were thoroughly tested, tested, and we have first-hand experimental data to verify the feasibility of the measurement method can be operational.
We found that the performance of different products is not the same dynamic clarity, not all plasma products has a good dynamic performance effects clarity. In general, PDP products generally better than the LCD product dynamic image clarity, but as technology advances, LCD products, dynamic image clarity has made great progress.
Test results show that with the acceleration of image motion, LCD dynamic clarity down with motion compensation technology products, significantly improve the dynamic definition. But at PDP dynamic definition of volatility, no significant decrease. As a result of some products of new technology to enhance the dynamic image display, has a good dynamic performance effects clarity.
Also be noted that the dynamic definition of the laboratory test results good or bad, does not fully reflect the actual image when watching the actual effect of product performance, the actual viewing experience, and many factors, such as environmental illumination, brightness, contrast , color reproduction and so on.
Average power 15% larger than the LCD
Now the problem of energy consumption caused widespread concern around the world, television as a mass consumer product, the power consumption is very important. But for the power of television, the standard is given rated power, standby power consumption of the test, but the rated power of the test for the flat panel TV product is not appropriate, especially for PDP TVs and LCD with automatic brightness control products, the measured power will be greater than the actual average power. In fact, television viewing during the average power consumption of the test is truly meaningful.
According to the statistics of IEC, the majority of television programs APL (average picture level) value of about 34%, can be seen, rated power consumption of the test does not mean that watching television during the actual power consumption.
Our bodies as IEC/TC100 the centralized management, has been tracking and participated in the research IEC/TC100 in the formulation of relevant standards and test verification work carried out to test methods specified by IEC 10-minute dynamic test image
