OLED lifespan

Leading manufacturers of OLED displays mass-produce displays, OLED displays are made from organic LEDs, such panels are called OLED displays. OLED screens began to be massively installed in phones, their merits were widely and widely advertised, and then LG began to make large screens that were installed in high-quality televisions and monitors.

But few of us know that a self-emitting LED gradually loses its properties, and a pixel loses its brightness. This was noticed by a lot of people, especially those who bought top-end phones with OLED screens. After some time, the screen faded and usually turned slightly pink.

Since the LED is supplied with voltage, which causes it to gradually glow due to chemical processes that occur in the material, it loses its properties, which leads to a deterioration of the display settings. The service life of materials in different most durable green pixels, red has an average service life, but for blue pixels, due to difficulties in manufacturing, most have a short service life. So, the brightness of blue pixels is lost in the OLED display and the screen turns red.

OLED life also depends on the brightness, the user sets a higher brightness, the more likely the display settings will deteriorate. Since OLED screens are fairly new, they have not passed the test of time, so we will not consider phone screens, as they seek to peacefully replace the phone in 2-3 years.

Thus, the life of OLED displays is about 30,000 hours, plus or minus 20%, that is, 1250 days or 3.5 years of continuous operation, of course, provided that on the working screen, the service life of 12 hours is 7 years. This term does not mean that the TV stops working, just the brightness of the blue color is significantly reduced.

red pixel 50000
blue pixel 15000

If the life of a blue pixel is 15,000 hours, then why is the life of your display 30,000 hours? The answer is that when displaying the image and displaying, the blue pixels are not always on. The average numbers are taken to calculate the life of the OLED display. And also, to reduce the load on the display, OLED displays are made with 4 types of pixels. To the traditional red, green, blue, white is added. Using a white pixel significantly reduces the load on other pixels.

QDLED lifespan

Displays on quantum dots are the same familiar LED displays, only new materials of increased purity are used as pixels for the material.
Thanks to this, the image quality is greatly improved.

However, the life of your quantum dot display is between 30,000 and 50,000 hours, according to the manufacturer. But in real conditions, they work much longer. It’s just that the manufacturer claims the average value from the calculation of the service life of the TV 7 years. After 7 years, service support for products ceases. Because of this, it is necessary to equalize all parts of the TV to a single product life.
