Watching TV and health, seemingly unrelated topics, is actually very relevant. From a certain point of view, TV is more like a contradiction product of pros and cons in a modern society. On the positive side, it deeply affects and greatly enriches people's lives. The attendant health problems are also a headache. Lack of exercise before sitting on TV, fat accumulation, the body is getting worse. Watching TV for a long time causes eyestrain and vision loss. Various problems deserve attention.
The impact of TV on visual health mainly focuses on color, brightness, viewing distance and other aspects. From a health point of view, black and white TVs may be better for the eyes because of their relatively low brightness. Color TVs can cause eye fatigue after long viewing, which can cause myopia. However, now the colorful pictures are more in line with the viewing pleasure of the general public. Therefore, how to enjoy the visual impact brought by colorful colors is a problem that must be considered.
In fact, the color of the TV can be divided into many different levels according to different technologies. The traditional CRT passes the electron beam of the electron gun to the fluorescent display screen, thereby producing a color image. But it will cause stroboscopic problems when scanning. Although CRT can achieve a real and gorgeous display effect in terms of color, the fatal defects of large screen and light weight cannot be achieved, and it is already destined to be eliminated.
The LCD TV adopts the principle of backlight, uses the lamp tube as the backlight light source, and achieves a more ideal display effect by controlling the light through the auxiliary optical module and the liquid crystal layer. Liquid crystal is a regularly arranged organic compound, which is between solid and liquid. It cannot emit light by itself. The electric field is mainly generated by voltage changes to change the arrangement of liquid crystal molecules to display images. When comparing color with CRT and laser TV, the LCD TV does not take the advantage. The reason is that the spectral fullness of the color of the LCD TV is poor, and the shades of the same color are difficult to accurately represent, and often the phenomenon of color cast or distortion occurs. Perhaps to compensate for this deficiency, LCD TVs often improve the visual viewing effect by increasing brightness and increasing saturation. This is why the LCD TV screens displayed in the store are bright and beautiful, like a fairy tale world. This beautiful color at the cost of distortion actually has an adverse effect on the viewer's eyesight, because bright colors and high brightness are very likely to cause viewers' visual fatigue and affect visual health.
In comparison, the 100-inch laser TV dazzle screen just launched has undoubtedly achieved a good balance between color and visual health. This is a product that is said to be eye-friendly. The reason why I dare say this is because its principle is completely different from that of traditional LCD TVs, but it is different, so it avoids many defects of LCD TVs.
The dazzle screen laser TV adopts the most mature cold light solid color laser light source, excites the three primary colors through the rotating fluorescent wheel, and then controls the reflection through the prism to the special scaly Xuanwu cold screen, and finally reflects naturally into the human eye. After the solid color laser imaging, the picture quality is very pure, so the color reproduction is high. According to estimates, the color gamut of the dazzling screen laser TV reaches more than 90% of the human eye, far exceeding 62% of the LCD TV, which can basically achieve the effect of true color. For the human eye, after the laser imaging, the picture is reflected into the viewer's eyes through the screen, similar to the principle that when we look at the natural scenery, it is reflected by the sunlight and reflected on the human eye, so the long-term viewing of the eyes Not tired.
In addition to color, there are radiation factors that affect the health of viewers. The principle of an LCD TV is a self-luminous light source, so radiation and power consumption will increase as the screen increases. The dazzle screen laser TV is a reflective light source, there is no radiation and damage from the self-luminous light source, and the power is only about 200w, which is one tenth of the same size LCD TV.
As people pay more and more attention to environmental protection and energy saving, the health problems caused by TV will become more and more prominent. Not only must the colors be beautiful, but also the eyesight must be protected; not only the impact of the large screen but also the electronic radiation must be avoided. All of the above have raised new issues for TV manufacturers, and will also become an important reference index that more manufacturers cannot ignore during product design and development.
