Research reveals: Watch the 3D TV not obviously influencing the health appropriately
The near future, China electronic the intersection of association of dealers and consumption electronic product investigate office unite the intersection of Peking University and the intersection of mental hygiene and research institute from psychology of human body, the physiology launches testing with experiencing several respects subjectively that studies to the characteristic of the 3D TV, so preliminary as to appear through the scientific experimentation of testing the sample to 30: Watch certain time 3D TV will aggravate brain sports, but not seen symptoms such as the obviously uncomfortable, anxious state of mind,etc.. Give up, buy doubt health problem difficult to block the intersection of 3D and the intersection of TV set and market popularize The 3D TV is listed on Chinese market and sold for nearly two years, the penetrance of product market is close to 20%, become the standard configuration in China high side dull and stereotyped TV model China 3D function especially. The present stage, consumer more and more high too in concern about 3D TV, China electronic the intersection of association of dealers and consumption electronic product investigate the office surveys and studies the data to reveal newly: Consumer's concern about 3D TV has already been up to 72.5%. The data reveal, the degree of attention to health factor is only ranked after the price when consumers choose the 3D TV at the same time. And see the 3D TV and really have direct influence on that the health is, which influence to have, most consumers are not totally clear. Extreme symptom of it is dizzy to appear, having dim eyesight, vomiting after it is reported that watches the 3D TVing etc. is an specific phenomenon, generally exist? Investigated the office unites what the research institute of the mental hygiene of Peking University launches together by the consumption electronic product of electronic association of dealers of China " 3D TV and health subject research " Lasts three months, having tested 30 samples altogether, the age range of the person tried is in 18-45 years old. The content of the test is mainly monitored and compared with the person tried while watching 2D TV and 3D TV separately, whether physical sign of life such as heart rate, blood pressure, brain wave of the person tried have change differences, it is anxious to be filled in separately by the person tried at different stages when test at the same time and experience commenting scale and the human body subjectively commenting scales, depressed, with oppose than analyze psychological condition change with human vision experience. Through synthesize psychological or physiological, brain activity, experience, discover by three test of subjectively: Compared with watching the 2D TV, the person tried watches certain time 3D TV, basically there is not difference between psychological activity and physiological state. Experience the respect subjectively, experimenters appraise 2D TV definition better, watch 2D and 3D TV at the same time, other eye experience subjectively and luminance experience have obvious difference. Compare with and watch 2D and 3D TV, experimenter's brain activity demonstrates the prominent difference. The mental hygiene Sun Li, researcher of research institute in Peking University analyzes that is thought, this may be with watching in 3D video course, the cognitive load tried improves and has something to do; Also may be the side effect that visual fatigue, discomfort that the structure of the glasses causes produce. Subject research compares different kinds of shutter type 3D TVs at the same time, the result reveals, direct against plasma and liquid crystal two kinds of different kinds of TVs, the person tried is too psychological or physiological to see the obvious difference while testing; While testing subjectively, the person tried appraises to the definition of two kinds of different displays unanimously better, meanwhile, the plasma TV experiences the respect to display at stereoscopic result and eye symptom better than the liquid crystal TV, and the liquid crystal TV mainly perceives the respect in the luminance better than plasma. Grandson's neat sharp point engineer says in a digital television standard according with detection of engineering letter, the difference of principles because of giving out light, it is an objective reality that plasma and liquid crystal 3D TV perceive the respect and display and go on business in the definition, luminance, stereoscopic result of picture differently. The Deputy Secretary-general of electronic association of dealers of China, famous electrical home appliances expert's land edge unexpected turn of are pointed out, have reflected mankind's development and demand from level movie TV to stereoscopic movie TV in the visual respect, external vision irritate psychological or physiological to have clear influence to people. Under this background, it seems particularly essential to study the 3D movie TV and difference of impact on human psychology of 2D movie TV employed extensively at present, employ and consult function importantly in guiding the science, health of the 3D TV. Look at present, the attention degree that major color TV enterprises such as Panasonic, Samsung, Konka, LG, Changhong,etc. are healthy to color TV products and human eye is very high. Relevant " 3D TVs and health subject research " It is one that work for a long time, will hope to have more Chinese and foreign 3D TV technology research and development, manufacturing company and 3D content to make enterprises and participate in too.
