Three years - roughly the marketing incubation took to the idea of curved TVs to the latest news of technical publications was embodied in a standalone segment products. During this time, the sky-high prices for curved panels down to a reasonable (but still considerable) sums, and manufacturers began to promise full participation, unprecedented realism of the images and a flat stomach in exchange for the abandonment of flat-panel TVs.
The tendency to curvature of the screens can be called pure evolution, such as the parallel implementation of 4K. However, if the advantages of increasing the resolution are very clear without explanation, in the case of curved displays often have to be guided only by marketing texts. As part of this post will try to analyze how manufacturers are honest with customers, talking about the merits of the products of this segment.
Curved - means more
Technology curved panels originally presented inextricably with wide screen that automatically classifies this type of televisions and monitors in the entertainment niche. In fact, the idea of changing the radius of the web to the demonstrations was born long ago: first in the theatrical business, and then successfully migrated to the cinema to increase the panorama. Now curved screens are commonly used in theaters and IMAX in particular.
By the way, the example of the first IMAX in promoting models of curved TVs will be an excellent starting point to explain the advantages. Following kinship along a curved, concave display supposedly can achieve a similar immersion in what is happening is not worse than in detail thoughtful cinema. In fact, the bent sheet in IMAX almost the least responsible for the "presence effect", as this form allows you to solve a number of technical nuances associated with the propagation of light and the projector. This immersion is achieved by bending the screen, along with its enormous dimensions that do not allow to embrace the entire width of the eye.
Given all of the above, the immersion similar to the famous cinema system and really at home, but given the fact that the TV is literally from all sides "to embrace" the viewer. This can be achieved by devastation on such a model as a Samsung UE78JS9500
or more budget process - to sit down close to the TV at a diagonal.
However, no precise recommendations for determining the optimal distance from the TV to "dive" no. Furthermore, if while viewing spectacular film in high resolution this way, coupled with the curved TV model will be partially justified, the news broadcast in this format result in risks to the demonstration panoramic figures of politicians directly into the living room. So here it is better to think about ecology and ophthalmologic problem of perception through the eyes of a curved image, abandoning the idea of immersion.
In this respect, scientists for several centuries exploring mechanisms of vision. Thus, we introduced the concept "horopter" - a kind of a conventional surface in sight in the form of a circle comprising a plurality of points in space. These points are projected on identical terms retinas different eyes (corresponding points) and give a complete image. If the conditions are violated correspondence with the perception of different points (horopter is), then it may cause double images. In general, the theme is very interesting, easy to understand and to be somewhere at the intersection of the field of psychology of perception and ophthalmology. However, these theories refers to manufacturers when it comes to what your eyes are more receptive to the curved image. TV at the same time must be set to such a distance that the angle allowed to "capture" the image from the screen completely. Only in this case the side points located to the left and right edges of the screen, as well as the central point between the two, will be equal to the distance from the viewer's eye. Thus the only correct position for the viewer of a science - exactly in the middle of the TV. But more on that later.
With regard to recommendations for a final example, the on this subject, there are many theories and methods of determining the optimal distance from the TV. Instructions on THX
have long been respected and, importantly, very suitable for our case. Online there are many different калькуляторов
to calculate the distance, which are based on these recommendations. According to them, for comfortable TV viewing should take 36-40 degree angle. At the same time, which is quite logical, the distance varies depending on the resolution of the model. For example, a 55-inch screen (as an option - LG Ultra HD 55UC970V a >) will have to leave about 3 meters.
At the same time, there are prerequisites for the emergence of market monitors is much less curved dimensional diagonals. Thus, according to исследованию
, various kinds of information on the curved screen perceived better than on the flat.
First developed a prototype model of the monitor, radius of curvature which can be changed with uncomplicated structure. Instead, today's displays, however, were restricted to a sheet of paper with interchangeable images.
This results in a 23-inch "monitor" with a ratio of 16: 9 on which the subjects first chose the optimal radius of curvature of the blade, and then one by one with a flat screen configuration attempted to take a variety of information. The conclusions of the experience is available with a small sign, which shows the results of measurements of time reading the same text on the flat and curved display. According to them, the curved shape makes it easier to learn the material that is quite possibly due to the above theory horopter line.
Returning to the theme of the promised right side. Studying the promotional materials to various curved TVs, you will notice that depicted spectators sit exactly in the middle of the TV. It is this attitude combined with a properly chosen distance will provide all the advantages of a curved display. If you want to arrange such a television family watching a movie, many remain deprived of technological buns. However, this has its advantages: According to an illustration from LG, curved panels bring together.
Finally, the curved shape of the display, according to a marketing legend, able to visually enlarge the area of the screen. And in fact, this is the truth. Since the actual width of the panel is reduced due to the radius of curvature along the whole panel, we can see all exactly as much as the display is folded at the corners. Moreover, the visual indicator will vary depending on the distance of the viewer. But change is in an ideal position to monitor how the magic becomes irrelevant.
Approximately the same situation with the view that the curved shape allows to increase the contrast on the sides. Universal answer to this question will not work simply because the manufacturers use different matritsy.Odnako even if the form of dimming and compensates for, then for one viewer, who will sit in the center front of the screen. The rest of the audience, by contrast, can watch the image distortion.
Instead of outputting
The curved panel - a relatively new phenomenon and it is difficult to say with certainty whether there is for them the future or not. For family viewing is perhaps not the best option, since curvature means a certain zone for comfortable viewing. But the curved display (eg such as Samsung S34E790C
, about which told Boomburum
), before which will sit in the center of one person - it is quite another matter. In any case, from this trend, we will not hold your hand, so to find the answers, we'll tell you about the curved monitors and TVs from different manufacturers - stay tuned
