- Top 10 questions about surface TV consumers -
1. What are the advantages of curved TVs compared to flat TVs?
First, when you look at a curved TV, the viewer will experience a sense of immersion as if watching IMAX.
Second, based on the structure of human eyeballs, a “flat-lined planar image†has been developed to further enhance the viewing effect.
Third, regardless of which angle, you can always get the best viewing results.
Fourth, it is worth mentioning that curved TV can also increase attention and present another visual surprise to the audience.
People in the city will really play, right?
2. Does curved TV simply bend the screen of the flat TV?
Seeing this problem, my heart is almost collapsed.
Curved TVs are much more than just bending the screen. From an external point of view, although the screen is only a thin plate, in order to “imageâ€, the substrate contains a very complicated circuit, such as a filter for coloration, a TFT substrate that adjusts the color by current, and is located between the two. It is a liquid crystal cell that controls the brightness and direction of light. In addition, it is also equipped with a "back light", a polarizing plate, and the like. Because even if the screen is bent, each part must maximize its normal function to ensure perfect imaging. Therefore, curved TVs require specialized spare parts and special circuit designs. If the screen is simply bent, light leakage and color mixing will certainly occur.
3. The greater the curvature, the better?
The answer to this question is: not.
The curvature of a curved television screen is called curvature. For example, "curvature 4000R" refers to the degree to which a circle with a radius of 4m is bent. In theory, the best curvature of a curved TV is the distance between the viewer and the TV screen, that is, starting from the center of the screen to the screen boundary, and the viewing distance is the same.
However, the problem is that the TV size of each TV is different from the size of the living room in which the TV is placed. The curved TV maker has done all the possible variables (living environment, watching TV habits, living habits, etc.) in order to find the best audio-visual distance. Research and analysis, finally calculated the best curvature, which is what we call - "golden curvature."
4. What is the reason why a curved TV can present cinematic audiovisual effects?
Curved TVs and the huge screens of IMAX theaters are similar. When watching IMAX movies, the reason to experience the grand feeling of liveliness and extreme immersion is that IMAX is a curved screen. The curved surface is more open than the flat surface. When watching a program on a curved surface television, the line of sight can be covered, so even at home, you can feel the feeling of watching a movie theater.
The important thing to say three times: At home watching curved TV has the feeling of a movie theater, movie theater, movie theater, movie theater!
The University of Ulsan, South Korea, conducted a study on the "curvature of curved surfaces and viewing experience". The survey results showed that subjects watched 55-inch curved TVs, compared to flat-screen TVs of the same size, a sense of space (feeling to integrate into movie space when watching movies), and a sense of participation (when watching a movie, integrating into a movie and participating in The feeling of performance was increased by 1.25 times and 1.11 times, respectively.
5. Why is the quality of curved TVs better than that of flat TVs in the same specifications?
Image quality is determined by factors such as screen resolution, color reproduction, and contrast. Among them, the color reproduction power and the contrast change with the viewing angle of the audience. The change in the viewing angle from the center of the picture to the edge of the line of sight will result in different levels of color reproduction and contrast. When viewers watch on a curved TV, they can achieve the best viewing angle regardless of their viewing angle (the line of sight is 90 degrees to the screen). Therefore, viewers can enjoy the perfect picture quality from the “central region†or “edge zone†when watching the program on the curved surface television.
According to the China Electronics Industry Standardization Institute (CESI) of the Ministry of Industry and Information Technology, the external contrast of a well-known display company's 65-inch curved screen (4000R) is up to 48% higher than that of a flat screen. Duang~! The superiority of surface television in picture quality has been further verified.
6. Only the "Emperor" viewing effect is the best, other locations are generally effective?
How can a family have "differential treatment" when they watch TV together? We are tired of logging!
When you watch TV programs on curved TV, you can experience excellent viewing results even if you are not in the central area (best viewing area).
Remember "golden curvature"? Ensure that you can get the same viewing distance from any location, vertical viewing angle, quality without deviation. In order to find the "golden curvature," curved TV makers have studied the data collected and measured on things such as the length of sofa armrests and the length of the living room. The ingenuity of the manufacturers is that they can enjoy the perfect high-definition picture quality through curved televisions, regardless of the number of people or the number of people watching. According to the test report of China Electronics Industry Standardization Institute (CESI) of the Chinese Ministry of Industry and Information Technology, the brightness consistency of a 65-inch curved TV (4000 curvature) produced by a well-known display manufacturer is 14% higher than that of a flat-screen TV. The clear picture quality of curved TVs has been objectively verified. Of course, it can also be called "golden curvature."
7. Why is curved TV called "Health TV" or "Ergonomic TV"?
Watching TV can cause retinal damage? Scared to death baby! However, now can rest assured that the starting point of the "curved TV" is the study of the human eye.
Human eyes are spheroids, so the retina attached to the surface of the eye to recognize things is also curved. When planar objects are imaged on curved retinas, problems such as “inconformity with the ontology of things, distortion, and so on†must occur. The eyeballs will automatically correct the image, so it will also produce a certain degree of fatigue.
However, when watching a program on a curved surface television, the image will be accurately displayed on the surface of the retina, which of course effectively solves the problem. The Beijing Eye Hospital Association conducted an experiment called “Complete Curved TV vs. Flat TV, Comparing the Degree of Human Eyes Watching Fatigueâ€. The experimental test results showed that when the subjects were watching curved TVs, the eyeball activity was significantly smaller than watching flat-screen TVs. The degree of retinal damage (as judged by the degree of dryness of the eye) also decreased. Curved TVs will become a new audiovisual model because of their "comfort degree of health" when they watch.
8. Will concentration efforts be improved through curved TV lessons?
No one wants to lose the child at the starting line.
The Korean Institute of Science and Technology (KAIST) conducted an interesting experiment. The experiment content is a video course for watching the same content through curved television and flat TV. When the volunteers watch through different televisions, the sight lines are concentrated on where. The eye tracker (eye-tracker) was used to measure the part of the line of sight that the students focused on during the video course. The focus of the line of sight measured by the eye tracker is marked with a red mark. When watching a video on a flat-screen TV, the student’s line of sight is not fixed at one point, but is scattered. When watching on a curved TV, students’ eyes are mainly concentrated on the teacher and the notes on the blackboard. Curved TV's screen structure is conducive to the students focus on the attention and attention to the teacher and the course content, so watching the video course through curved TV, the learning effect will of course increase step by step.
9. Can curved TV really not hang on the wall?
But as the saying goes, it's better to see it. As can be seen in the picture, the flat TV can be elegantly and conveniently hung on the wall. Curved TVs change the inherent style of home improvement style through its inherent “elegant curves†and maximize the effect.
10. How to pick the right curved TV?
Starting this year, TV manufacturers such as TCL, Hisense, Konka, Changhong, Haier and Samsung Electronics have all launched curved televisions. Curved TV allows consumers to experience an unprecedented audio-visual experience through its "extremely immersive, superior appearance, ergonomic design." Curved TV will become the mainstream voice of the TV market has gradually sounded.
Because the curved TV models on the market are various and their designs are different, it is very difficult for consumers to pick the best products when they buy curved TVs. The creation of a special website that includes all the related issues of curved television has brought about the above problems.
