What is OLED? What is ULED? Is it a family with LED?
LED is an abbreviation for LCD (liquid crystal TV) using LED light as backlight. It is an upgraded version of CCFL cold cathode backlight LCD.
ULED is still relying on LED backlight to illuminate the pixel image of the TV. It is also a category of LED TV or LCD TV. At the same time, ULED TV also added quantum dot technology and multi-partition independent backlight control technology, which is superior to traditional LED TV in color performance.
Although OLED also has the LED word, it has nothing to do with LED. OLED is the abbreviation of Organic Light-Emitting Diode. It is a pixel-based self-illuminating TV technology that does not rely on backlight. Therefore, it is not in the category of LCD TV. Is a completely different TV type. Due to the self-luminous properties, its color is generally considered to be superior to LCD TVs.
Dark field contrast: OLED black performs better
OLED is a pixel-spotted self-illuminating TV, so when the black color is displayed, the relevant pixels can be turned off, so the black performance is very good.
Regardless of how the technology upgrades the LCD TV, its imaging principle cannot be changed. Even with the partition backlight control technology, it is impossible to control the illumination of each pixel. Therefore, the performance of black is weaker than that of OLED TV. Let's take a look at the actual experience. .
