Company News >> TV panel technology comparison: LCD, OLED and plasma who can win? 13th,July,2017
                                               The current TV panel technology is mainly divided into plasma, LED LCD, as well as new OLED. OLED is one of the manufacturers focus on publicity, LCD sales of the highest, and plasma is the majority of TV critics heart love.
So which of the three panels which is the best? For those who intend to buy TV, it should be waiting for OLED, or in the plasma before the death of a purchase, or in the countless LED LCD which choose? Technology website CNET recently on the author of this issue:
First come to the terminology.
LCD TV from the size of dozens to 90 inches range, each TV manufacturers have their own LCD products. And all the "LED TV" is actually LCD TV, but they use the LED as a backlight. So the text of the LCD can also be seen as LED.
OLED current price at $ 9,000, only 55 inches a screen size, the choice of brand only Samsung and LG.
Samsung and LG also produced plasma TV (unfortunately, Panasonic has been out), the size of these products in the screen between 42 inches to 65 inches.
In addition you may have heard of the "4K" super clear this concept, but this refers only to the resolution. At present, only LCD can achieve 4K resolution.
The following is a comparison of specific projects:
Light output (brightness)
Win: LCD, OLED (to some extent)
Failed: Plasma
OLED is brighter than LCD, and vice versa, depending on how you calculated it. Because the LCD uses a backlight, so their brightness is determined by the backlight. The pixels on the OLED panel are self-luminous, so there is a limit (plasma is the same, but not as bright as OLED). So in the white screen, LCD brighter; and if the black screen on the white rectangular pattern, the OLED "white window" is brighter than the LCD. The latter situation is closer to the regular TV content, that is, at home watching movies and television shows, OLED looks brighter.
It is worth mentioning that, although the plasma is not as bright as the other two panels, but the brightness is not everything. Anti-glare or anti-reflective coating will play a big role in watching TV during the day.
Black level
Win: OLED
Failure: LCD
Runner: Plasma
Because OLED TV can turn off its own pixels, so their black level is almost perfect (that is, almost no light will be emitted from the screen). Plasma can also control its own pixels, but can not achieve absolute black (always light). From a technical point of view, LCD TV can turn off the backlight to achieve absolute black, but this can not be achieved, because this way the audience can not see the image. Local dimming will help, but in actual use, OLED is the best. And this problem is also related to the contrast.
Contrast
Win: OLED
Failure: LCD
Runner: Plasma
Contrast is the contrast of the brightest and darkest areas of the image, and it is the most important factor affecting the overall picture quality. A very low contrast screen looks plump and flat; on the contrary, high contrast will make the picture look more real, "depth of field" larger.
Since the OLED can turn off the pixels, the contrast is infinite. After a lot of demo on the OLED TV, the author can say, OLED TV picture effect is absolutely better than any TV you have seen, whether it is plasma or LCD.
Partial dimming function of the LCD can also have a good contrast, although there are some differences between high-end plasma.
Panasonic's ZT60 plasma TV has excellent native contrast, it is also one of the best TV this year. OLED TV is better, but the best plasma TV looks great!
