What is fake curved TV
To identify what a TV is a fake surface, you must first know that the surface is true. True-surface TV is based on organic light-emitting diode technology, that is, OLED TV, which is connected to the positive electrode of electricity by a thin and transparent indium tin oxide (ITO) with semiconductor characteristics, and another metal cathode is packaged as a sandwich. structure. True curved TV has the advantages of thin screen, good color gamut, low energy consumption of active illumination, no viewing angle limitation, and high softness of the screen. However, due to the high cost, the selling price is generally higher. However, the market demand continues to grow, so some manufacturers began to use LED's idea to imitate the external form of OLED curved TV. The original flat LED was forcibly bent into a curved surface by external force, transformed into a new curved form and flowed to the market, and sold. High price. However, the high price of consumers is not a high-quality product. Because in the process of bending the LED by external force, the liquid crystal molecules are squeezed, which may cause problems such as screen leakage, TV life degradation, and uneven image quality.
Because the fake curved TV is a curved LED display screen that cannot be bent arbitrarily, the television is forcibly bent into a curved shape by physical external force. LEDs are made up of many components. When the screen becomes a curved surface, these components can't be curved. This is the main reason why the LED curved TV body is thicker and even the back is still flat. Due to the poor flexibility of the LED screen itself, there are major technical defects in physical bending.
The surface of the curved screen is more beautiful than the actual one. Whether it is the past plasma HD, today's 4K, or the fiery curved TV, it is essentially a TV, it should be the visual experience. Of course, in the living room aesthetics is more important today, the appearance of the TV has also received attention. The beauty of curved TV is its biggest selling point and product differentiation, it is easy to win the curiosity of consumers and enhance the brand's awareness. The industry observers believe that LED curved TV will sacrifice huge practical value while gaining aesthetic points. This sacrifice is reflected in the following aspects:
The requirements for the screen are even greater. The curved screen can only show the visual advantage under the big screen condition, forming a wraparound viewing experience. So, if a flat-panel TV is 55 inches in size, a curved TV needs at least 65 inches to achieve a similar effect.
It is not convenient to hang the wall. Its thickness is large, and there are certain hidden dangers in the curved and extended edges. The most prominent problem is that curved TVs have a "bow-like" shape, and the edges of the screen look larger than the middle, especially when displaying horizontal content across the screen. When you move the viewing angle, the screen becomes more distorted.
High requirements for light. The ordinary spotlight TV wall is not very suitable for curved TV, and the family needs to carry out some additional lighting design to meet the lighting requirements of curved TV.
A trick to the surface of the TV is true and false: whether the screen is an OLED screen
False surface TV: LED screen. LED screens are a technical step backwards. Because it does not bring any benefits to consumers, it has been increasing costs, it is only a change in shape, but it also makes consumers pay more. The LED screen itself is not designed for curved surfaces and consists of many components. When the screen becomes a curved surface, these components can not be curved, which is the main reason why the LED curved TV body is thicker and even the back is still flat.
The performance of these technical defects is as follows: First, the process is hard to bend and bend the screen, easy to leak large areas; Second, the thickness and weight of the fuselage are multiplied; Third, the viewing angle is less than 76 degrees, only suitable for single viewing.
Some consumers have reflected that a curved LED TV in actual use, when viewed at a non-central point position, the surface of the curved TV will be deformed, and this deformation phenomenon will become more serious as the TV screen shrinks.
True curved TV: OLED screen. The curved TV of the OLED screen is not fully mature. What is questioned is the service life problem. It is difficult to conclude how long the OLED screen curved TV can be used. This is a reasonable reason for the mobile phone. The key is to look at the personal use situation. The long life span is short, and the long life is long.
The display technology of OLED is more than 20 or 30 inches on the screen. After reaching the panel size of TV, the problem of OLED is many, and it has not been solved for many years. For example, the light source has fast decay speed, short life, technical defects, and the image display is too bright. It is not natural enough, so OLED is today, and there is really a promotion value, and it is a small-sized screen area of 10 inches or less, such as a smart phone and a small-sized display device.
