Compared with the advantages of LCD and LCD, who is more cost-effective?

OLED is considered to be the next generation technology that can replace LCD, so it is in many respects that there is no small advantage. This is beyond doubt.

OLED advantages

First of all, the most worthwhile advantage, of course, is the black level of OLED TV. The so-called black level performance is simply how black the TV can be. At this point, it is strange that the OLED screen that can completely turn off each pixel is not the winner. Of course, some LCD TVs also have regional dimming technology, but this is still not as delicate as the black level of OLED, and it is not perfect black. Even the LCD TV of the first echelon, some "dizzy" phenomenon is still inevitable.

Then after saying the black level, you must definitely mention the contrast. The so-called contrast is the difference that a TV can do between the brightest and darkest extremes. OLED is the winner because it delivers absolute darkness and excellent performance in very bright scenes. For the general standard of picture quality, contrast is one of the most important attributes, it can make the picture look more realistic.

Just mentioned the backlight of the LCD TV, which also led to its poor performance in the uniformity of light, that is, the brightness of the screen is not even. At this point, the edge-lit backlight system is particularly noticeable, and there may even be edge leakage. OLEDs perform better at this point, but they are not perfect, especially in early OLED TVs where there was a problem with parts of the screen that looked slightly darker. In addition, the curved surface of the OLED screen also causes unevenness to some extent.

Next, one of the strengths of OLED is the viewing angle. In fact, this is one of the weaknesses of LCD TVs. OLED TVs do not degrade significantly in brightness and color, no matter how extreme they are, but LCD TVs cannot do this. Although some LCD TV panels have better off-axis display technology, the price is relatively low.

LCD advantages

We all know that one of the advantages of OLED screens is that they consume less power, because in the dark places in the picture, the pixels can be completely turned off, thus achieving the best power saving. Surprisingly, however, LCD TVs are often no worse than OLED TVs in terms of actual energy consumption, and even better. First of all, the power consumption of LCD TVs is almost only related to the brightness of the backlight, making its energy consumption performance very stable. OLED TVs need to be more power-efficient, unless the image content itself is a darker type, otherwise it can only reduce the brightness as much as possible, and the contrast performance of the OLED screen is very sensitive to brightness, making this compromise very uneconomical.

Of course, OLED phones and OLED TVs are different in positioning. The mobile phone has limited battery life, and the TV always has a power connection and is extremely heavy in quality. Therefore, it is said that energy consumption is the block, OLED TV is still really winning LCD TV.

If you like big screen TVs, then LCD may be a better choice. LCD TVs are very versatile in screen size selection, from less than 20 inches to over 100 inches. Perhaps because of higher production requirements and fewer suppliers, current OLED TVs are available in three sizes—55, 65, and 77. Among them, the 77-inch TV may have to go to the level of 100,000 yuan in the price. So as an ordinary consumer, if you want a TV that is smaller than 55 inches or larger than 65 inches, then at least for now, there is only one LCD option.

Of course, as a new product, the price of LCD TVs is certainly cheaper than OLED TVs. If you can, you can buy a high-end LCD TV from the past, and you will find that it will not perform badly. In addition, LCD TVs also have considerable advantages in overall brightness, but since OLED TV itself is not too bad, this advantage is almost negligible.

Although we have compared the advantages of many OLED TVs and LCD TVs, they are actually flattened in many places.

For example, the resolution and HDR that everyone emphasizes today, in fact, OLED and LCD do not have any advantages or disadvantages in the implementation of these two technologies. Needless to say, the resolution can reach the most popular 4K level. As for HDR, both TVs also have models that support this technology. Although there are subtle differences between the two in HDR presentation, such as LCD can bring brighter performance, and OLED is better in overall contrast, but the overall difference is not great.

The other two are also tied in an important area, that is, their support for the wide color gamut. The so-called wide color gamut, in simple terms, is in a set of colors that have been developed, and the product can cover most of the scope. In other words, such a TV will be more diverse in color rendering. In theory, whether it is LCD TV or OLED TV, they all support the wide color gamut standard. Hard to distinguish between a winner and a loser, can only say that the vast majority of OLED TVs support the wide color gamut, and only part of the LCD TV (mainly Samsung's QLED products) to achieve such standards.

So when we talk about it, how do we choose? If you think that there is only one basic requirement for image quality, and you still want to pursue low prices, then LCD is worth considering. Of course, what I said here is to buy the new LCD products of the year. It is also good to be able to find the middle and high-end LCD TVs in the past.

However, as long as there is a certain demand for image quality, it is better to buy OLED TV. Because OLEDs are more technologically advanced, you can get a much better picture quality at the same price point of view. Even if the price of OLED TV is relatively high now, as the demand increases, the cost will definitely drop. Moreover, now we have seen a lot of well-received mid-range OLED TVs (such as LG's OLED full lineup is almost the same in picture quality), to pursue a better experience, or consider OLED.
