How does Oled Pixel Refresher Work 📺 2022

Would you like to learn about “how does OLED 'pixel refresher' work”? Yes? Good, let’s get started!

In general, the 'OLED pixel refresher' works by gradually changing pixels and colors ('Pixel refreshing'). 

It automatically detects pixel deterioration through periodic scanning and may fix it, if necessary.

The detection works by sensing any TFT ('Thin Film Transistor') voltage changes during power off.

The definition of 'pixel refresher'

'Pixel Refresher' is a feature that helps to prevent temporary image retention.

On Sony TVs the feature is called 'Panel Refresh' and LG calls it 'Pixel Refresher'.

It may be manually or automatically activated.

When should I run the 'pixel refresher'

2000 hours or more

According to LG:

When the accumulated television viewing time reaches 2000 hours or more (this is equivalent to watching TV for five hours a day over the course of a year), 'Pixel Refresher' will be automatically
activated once your TV is turned off.

When turning off your TV, a notice will appear on the screen informing the activation of Pixel Refresher. This feature will run for an hour while your TV is turned off. A horizontal line may appear at the top or bottom of the screen when the process is almost finished.

It may take up to an hour.

Four cumulative hours of viewing time

According to LG:

Whenever you watch your TV for more than four cumulative hours, 'Pixel Refresher' will be automatically activated for a few minutes once your TV is turned off. (Note: 'Pixel Refresher' will not be
activated if the power cord of your TV is not plugged in or the main power is off.)

It should take up to 10 minutes.

How to activate the 'pixel refresher'

You may also manually activate 'Pixel Refresher' via the TV menu:

Picture, OLED Screen Saver, 'Pixel Refresher'.

Is 'pixel refresher' bad?

You shouldn't use the pixel refresher more than the manufacturer advises you to.

It is a proactive approach to prevent image retention but may also artificially age your TV. So be careful.
