The difference between LCDs and OLEDs are how the images are produced. LCDs utilize liquid crystals that produce an image when light is passed through the display. OLED displays generate images by applying electricity to organic materials inside the display.
Black level: OLED wins
The black level refers to how "black" the screen can be when displaying the darkest color. Since technologies such as LCD, DLP or projection rely on filtering or shielding of white light, it is very difficult to display true black. In fact, it can be said that the LCD screen cannot bring true black at all. After all, no matter how good the shielding effect is, there will still be some light leakage. On the other hand, due to the self-luminous principle of OLED, as long as the light-emitting mechanism is turned off, it can bring true black.
Contrast ratio: OLED wins
Contrast refers to the difference between the brightest whites and the deepest blacks, and while LCDs have an advantage in brightness (especially in HDR mode), OLEDs have the deepest blacks. OLED displays generally have higher contrast ratios in general, because the difference is magnified by the advantage in black level.
Viewing angle: OLED wins
Perhaps the best IPS screens can match the viewing angles of OLED displays, but most LCD displays don't perform as well as IPS (especially TVs and smartphones), so except for the top IPS displays, Compared with OLED panels, LCD panels have slightly worse viewing angle performance. In front of an OLED TV, no matter which angle the viewer sits at, they can see the content on the screen with a high-quality feeling.
Brightness: LCD wins
Since LCD TVs usually use a separate backlight, this generally results in better brightness. In reality, there is about a 400NIT difference in brightness between the best LCDs and OLEDs, and LCDs are generally better at brightness levels. You know, higher brightness will make the screen have better visual effects outdoors or indoors during the day.
Power consumption: LCD wins
At the same brightness level, LCD consumes less energy than OLED. This is a problem we have to face. For mobile devices, higher brightness means better visibility outdoors, while products such as TVs only need to have enough brightness during the day.
On the other hand, the power consumption of OLED panels depends on how many pixels there are, so OLED screens with higher resolution consume more power.
Cost efficiency: LCD wins
Currently, LCD is the lowest-cost display method, but OLED technology is constantly being optimized with the continuous progress and passage of time. The specific cost rate is not yet clear, but OLED technology will continue to improve in the future, and the cost will eventually be continuously optimized and reduced, and will eventually be comparable to LCD.
Summary: OLED is the best, but still needs development
Generally speaking, OLED wins the comparison of image quality parameters, so the future can be said to be a development trend of future display technology. However, OLED is still limited by the production cost, and the size has also encountered a bottleneck. Unless you have special requirements for a specific parameter such as brightness, OLED is stronger than LCD in most display parameters.
