In 2016, the color TV industry was known as the "large size" year. Because this year's over 60+ inches of ultra-large products will almost double the sales growth. At the same time, VR display devices have brought another "big" view of the enjoyment. However, do you truly understand the "big" changes when you embrace the larger television era?
Because the price is also because the demand is "big" is the future
Recalling the size of the best-selling flat-panel TVs, it is not the current super-sized products that dominate the overlord. In 2004-2005, 32-inch LCD TVs even accounted for more than 40% of the domestic flat TVs. why? Because at that time, the cheapest basic tablet is the 32-inch product: about 13,000 yuan. The same price can now buy high-end 65-inch LCD, or low-cost 70-inch LCD TV. - Therefore, the first precondition for the advent of the big TV era is "to be cheap." The average price of a 50-inch LCD TV is now between RMB 2,000 and RMB 3,500, and it is fully accessible to ordinary families.
The second reason for the popularity of big TVs comes from "content." If you don't have BD, HD, 2K, and now 4K, then a bigger TV can be a problem. If you only look at the content of the DVD, the size of the TV is large, but the screen will be "mosaiced", and the resolution is not as good as that of the small TV. This is the 2006-2008 year, the HD LCD TV popular "mid-term" phase of the consumer's most annoying thing. Now, the content market has formed two high-definition program sources, “Internet + Broadcasting,†and consumers have more high-definition programming content, which also requires a larger LCD TV.
The above two factors are strong and necessary. However, the real core reason for promoting the popularity of big TV lies in the "desires" of consumers.
The fact is that the development of the United States' big TV is earlier than that of China. At present, the proportion of big TVs in the Chinese market is higher than in Africa and Southeast Asia. That is, the more economically developed regions, the better the large-size TVs are sold. This law shows that consumers will try to buy products with a larger display area if the spending power allows. In fact, the history of human TVs is the "growth" history of 10-inch to 100-inch laser TVs. Among them, the development of flat panel display technology that now dominates the mainstream is based on the goal and pride of being able to build larger TV sets: For example, the 11th generation semiconductor display panel line of TCL's largest glass substrate size is about to start construction. The last largest record is The 10.5 generation line of BOE.
From 2006, the world’s first 60-inch LCD has a price of 188,888 thousand yuan, and the current 60-inch LCD has a popular price of 3000+. In the past 10 years, the color TV market has undergone extraordinary changes. This has also created the product and technology foundation that consumers “pursueâ€.
Big TV also has a bottleneck to watch distance relationship health
The television is getting bigger and bigger. Then, the question that comes along is how to balance the "viewing distance" and the "purchase size".
Before 2015, the 30-50 inch color TV has long played the leading role. The size of such a television, the viewing distance is often less than 3 meters. The space of 3 meters is safe for most families. That is to say, before the super TV becomes a trend, consumers only need to buy bigger products according to their economic ability. As far as the safe viewing distance is concerned, it is basically guaranteed.
However, since 2015, especially since September 2015, sales of TV products with 55 inches or more have increased significantly in the downward trend of prices. At present, the market size of 55-inch products has almost doubled in 2014. This makes the 50+ product the largest TV-sized market share. At the same time, the high-end color TV market, is the 65 + size as the next universal goal. That is, the color TV industry has entered the "super-large" era.
From the perspective of the health of viewing distance, 55-inch LCD TV is best to watch at a distance of 3.5 meters, 65 inches requires a distance of 4 meters, 80-inch products are expanded to a viewing distance of 6 meters. This kind of viewing space will constitute a "new health challenge" for ordinary families and houses under 120 square meters. Or, when the mainstream of color TV enters the era of super-large, consumers must first determine the viewing distance in order to purchase color TV products with different display sizes.
The reason for this change of purchase rules is very simple. Excessive viewing distances and excessive screens can cause the eye to receive more intense optical energy, resulting in faster fatigue. Even, it is not ruled out that close proximity causes the eye to adjust nerves, muscles, and photochemical cells to be highly stressed, exacerbating the occurrence of myopia, macular, and other lesions. Therefore, "big TV" cannot be bought casually, and it should become a new common sense of consumption.
Different display technologies have different viewing distances
How close to the viewing distance causes eye discomfort? The answer lies in the spatial distribution of the brightness emitted by the television. As the viewing distance increases, the geometric progression diminishes. Therefore, viewing at a reasonable distance will reduce the discomfort caused by brightness.
Since brightness is the core of TV viewing distance, what kind of brightness TVs do we normally need? The answer is that if it is an all-black environment, the basic display effect can be guaranteed with a TV screen brightness of 50cd/m2. However, during the day, the ambient light in the room is obvious. In order to counter the interference of the ambient light to the display contrast and the dilated state of the pupil of the human eye, the brightness of the television is preferably maintained at an energy value of 200-300 CD/M2.
However, the ideal theoretical value is also affected by many other factors. In particular, it will be affected by the specific display technology categories. For example, liquid crystal display technology, due to the use of the backlight light-emitting imaging, the screen is difficult to obtain absolute black, so to maintain the entire screen's contrast perception, you need a higher brightness level. This is why 50-inch LCD TVs are recommended for viewing distances of 3 meters, and plasma TVs and OLED TVs are more than 2.5 meters.
Currently, most LCD TVs on the market provide a brightness level of 500 CD/M2 or more. If the brightness is adjusted to the highest value, a viewing distance of 5 meters or more is basically required. So, using the recommended LCD TV, adjust the brightness menu to between 50% and 75%. According to different ambient light effects, different brightness viewing modes are needed. ——These tasks seem to be a bit tedious and are often overlooked by consumers when they use televisions, but they are related to health.
From the perspective of the development of future television and home display applications, the trend of “big†continues. Then, how can consumers get the effect of eye protection while “big� Can you just adjust the brightness level? the answer is negative. Because large-screen televisions destined for higher brightness energy output - 65 inches will exceed 4 32-inch energy output values, and the brightness will be adjusted too low, visual effects, contrast and sharpness will be lost.
The display industry’s solution to this is the introduction of new display technologies. This is OLED and laser television. In contrast to LCDs, 55 to 75-inch OLED TVs require 20% less viewing distance than LCDs. Because, OLED is a direct light-emitting technology, has a better "contrast" reduction capability, can guarantee excellent picture quality at lower brightness.
For viewing distances, the advantage of laser television is even more obvious. The laser television with a reflective optical path has a softer picture quality. Its minimum viewing distance can be further reduced by a quarter compared to OLED TVs. That is, the equivalent viewing size of a laser television allows a healthy viewing distance of only about 50% of the LCD TV. 100-inch laser TVs generally require a viewing distance of 3.5 meters. If it is reduced to 80 inches, laser television can meet the needs of the vast majority of home health watching (the LCD needs a viewing distance of 6 meters in this size).
Therefore, a reasonable viewing distance of a television needs to distinguish the types of display technologies and also need to adjust the specific brightness parameters of the products. The so-called relationship between viewing distance and TV size actually means that "large-size TV always outputs more energy."
The type of application is also important. The TV size is also based on the application
Understand the need for healthy viewing distances for different display technologies, learn to adjust the brightness of the best products under different conditions, and select the size of the TV in accordance with the size of the room. Do these three things make TV look healthy? The answer is still negative. Because there is another core factor "watching time."
As an example. In the movie theater, the screen is large, but the brightness is generally not high (this is in line with the consumer's pursuit of the immersive, immersive consumer experience, but also meet the health standards of brightness, screen size and total energy output), but the time spent watching the movie Long still feels "tired." The reason for this problem is that the immersive sensation brought about by the oversized picture also brings the “full input of the whole body sensesâ€, especially the nervous system of the eyes, ears and brain. - That is, it can be concluded that "immersiveness" is proportional to the size of the picture, and also proportional to the degree of exertion; a larger viewing screen means "the effective control of the viewing time."
In a movie theater, the normal viewing time is a movie. The length of time is not a big problem. However, watching TV at home is inevitably "funny." This determines the choice of TV size, but also need to consider two typical application requirements: 1. Long-term watching TV dramas, variety shows, 2. Just watch the movie on time and use it as a 2-hour private theater.
For the second application scenario, immersion is the primary purpose of consumption. In the case of meeting the “brightness health†and “distance health†standards, the screen size is a simple “bigger is better†principle. Since 2016, VR near-eye display products have become popular. Due to the near-eye approach, it can present visual effects that cover almost the entire field of view with the best immersion. This kind of product is a good choice for a movie home. However, its drawbacks are dizziness, spatial illusions and other physiological reactions, and products should not be worn for a long time.
For the first application case, the general standard is "not to cause fatigue because of the presence or sense of immersion." That is, the size standard selected by the television is: in the ideal viewing distance of the room, the size of the screen when the two eyes are directly looking, covering the width of the main field of view does not exceed one third to one half. According to this standard, if the viewing distance is 3 meters, then the corresponding screen size is almost 60 inches or less. Taking into account the higher display brightness of the LCD, if there is an economic basis, it is recommended to use OLED display technology products.
After the above analysis, the core meaning of TV shopping and viewing time can be summarized as: Larger screens are often more likely to cause fatigue, so larger screens mean “shorter†viewing times. This rule also determines that, from a health point of view, home TV 55-65 inches will basically become the final "mainstream TV size." After this, further increase in screen size does not meet the traditional "applying habits" of televisions for long hours of viewing. For families with a small size (100 square meters), it is not recommended to choose a model larger than 50 inches.
Good products have to be "good". Health TV must be used like this.
Admittedly, display technology has advanced by leaps and bounds in recent years. LCD TVs are getting bigger and bigger, and prices are getting lower and lower; OLED TVs are about to mature and gradually enter the market. Laser TV brings the era of private cinema and changes the viewing consumption pattern. VR products allow one to be able to Place to follow the "appreciation of the big screen."
While admiring the revolution in consumer experience brought about by these technological innovations, consumers should not forget that any technological achievement is a double-edged sword. For example, the epidemic of smart phones has led to a reduction in head ancestry, cervical spondylosis, vision problems and direct interpersonal communication. The large-scale and immersive TV sets will also bring about a series of health problems. In this regard, it is important to choose a scientific and rational TV size. It is fundamental to have a healthy habit of self-control.
The principle of watching TV for health can be summarized as follows: 1. The bigger and brighter the picture, the better. 2. Super large screen and VR must be used in a timely manner to rest, control the length of use time; 3. Don't watch televisions at close range, especially large-size TVs (you can't go too far to watch small-size products) 4. Keep correct sitting position, rest and adjust position in time, make simple exercise every 15-30 minutes; 5. Watching TV for no more than 4-6 hours a day, with a break in the middle; 6. It is best not to watch TV during dining.
Technology changes lives: This change should be good and beautiful, not damage our health. 2016 is even more popular for super-sized TVs. It should bring about the growth of people's viewing experience and more considerations for healthy viewing. It should not be a “pretentious†and blind application that harms health. This is the "basic common sense" consumers should face in the "Great TV era."
