Image Sticking

What is Image Sticking? What Causes Image Sticking?

Image persistence, image burn-in, and image sticking are terms used to describe LCD image retention. LCD image retention occurs when a fixed pattern is displayed over a prolonged

period of time. The fixed pattern causes a parasitic capacitance to build up within the LCD component, which prevents the liquid crystal molecules from returning to their normal relaxed

state.

All LCDs/CRTs and color plasma displays are susceptible to image retention, at varying degrees. Phosphor based display devices, such as CRTs and color plasma displays are most

susceptible, and image retention on phosphor-based devices is often irreversible. Transmissive devices, such as LCDs are less susceptible, and in most cases LCD image retention

can be reversed.

The rate of image sticking depends on the image pattern, duration of fixed image, the temperature, and production variations. Likewise, the rate of diffusion of the image sticking

(recovery time) also depends on these factors.

What Can Be Done About It?

The best way to avoid image burn-in is to limit the amount of static content on the display. Image sticking may be avoided by turning the monitor off periodically for a period of time

between 2 to 4 hours.

To reduce the possibility of image retention, we recommend:

Displaying alternating black/white images for 2 to 4 hours

Using a screen saver when the touchscreen is not in use

Image retention caused by static (non-moving) images displayed for lengthy periods (image burn-in) is not covered under Elo warranty.
