The development of society has created the third gender that human beings apart from men and women. It is pseudo-mother, not to mention discrimination, but the physical body of a man's daughter, after all, is that the functions of both sides cannot be realized normally. Nowadays, such a tragedy has also appeared in the color TV field. Originally, it was a "straight" man, but it was hard-earned "bending". It was a curved LED TV.
Here we have to explain that there are still some surface-mounted TVs such as ULEDs on the market. Although letters are added in front of LEDs, they are still LED TVs in the end, but they only have some performance improvements. Therefore, I also classify this kind of surface TV as a curved LED TV, which will not be described later.
Let's take a look at how curved LED TVs are born. In simple terms, the LED panel itself is flat. By physically bending the planar LCD substrate, it becomes a curved LED. Of course, this is just The first step. As we all know, the liquid crystal panel in addition to the glass substrate, there are backlight originals, glass substrates, "bending" is easy, but the backlight module is obviously not bent, so, from the physical form, the curved LCD panel is thicker than the flat LCD panel This is also why we usually reduce the thickness of curved LED TVs.
So, did the curved LED TV after the curve really evolved? Live more happily than flat LED TVs? The answer is of course negative.
Compared to flat-panel TVs, curved LED televisions have very high requirements for light. Under ordinary lighted TV walls, TVs produce some strange reflections of light. This is the commonality of non-planar glass, and curved TVs will increase. Reflecting the size of the object, in the non-dark environment, users will see distortion of the TV reflection object.
Curved LED TVs are said to have a wider viewing angle, but in fact this is relative. The only place where users can enjoy this wide viewing angle is the center of the sofa facing the TV center point, if the viewing distance is elongated or When the person on both sides of the sofa watches, they will receive the influence of the viewing angle of the screen and thus the deviation of color. Perhaps the color of the screen you see is completely different from the person in the middle of the screen. In addition to color, viewing at an angle of more than 35 degrees on the side will also feel a serious distortion of the picture.
In addition, related calculations show that the curved LED TV can reach the 55-inch flat-panel TV with 65 inches. We all know that the TV has an optimal viewing distance. Theoretically, the larger the size, the farther the best viewing distance, the curved TV. The best viewing distance in the industry is calculated by the curvature, which is the radius of the screen body. The curvature of mainstream mainstream curved LED TVs on the market is now 4200R, which means that the best viewing distance is 4.2 meters. For ordinary consumers, the living room can't satisfy this condition at all. If the distance is too close, it will cause the eye to watch. fatigue.
In most Chinese homes, TVs are hung on the wall to save space. However, the overall thickness of curved LED TVs is too thick to be as thin as flat-screen TVs. There is a certain risk of bending and protruding edges. Therefore, it is not suitable for hanging on the wall, which also greatly limits its target consumer groups.
Not only did the pride of LED originally belong to, but after curved LED TVs were bent, they still couldn't compare with natural OLED TVs.
OLED TVs have unique technical advantages for curved screens. OLEDs are self-illuminating, so the screen can be very thin and flexible, and theoretically it can be flexed or even folded without affecting the display.
The LED display screen is complicated because of its own components. It requires backlight modules, and the thickness is difficult to control, and the flexibility is also poor. It is not easy to make an excellent surface, and many problems will arise. Moreover, the LED curved television is not as good as the OLED surface in brightness uniformity, color uniformity, and viewing angle.
Therefore, from a technical perspective, OLED is the future of curved TV.
