Da li "Car" i "NSViper" mogu da okace neku sliku navedenih monitora sa duhovima ali da se vidi i neka nasa novina sa datumom.
Hvala...
Evo ti da se 'usrecis' :d

What Causes Image Sticking in TFT LCD Displays?
Image sticking is an intrinsic behavior of TFT LCD panels. It is the result of their susceptibility to polarization of the liquid crystals inside the display panel when a static image remains displayed on the screen for too long.
This results in a parasitic charge build-up, or polarization, within individual pixels and sub-pixels. This polarization takes place at the liquid crystal level in the LCD panel; it affects the crystals' optical properties as it prevents the liquid crystals to return fully to their normal 'relaxed' state upon deactivation.
More specifically, the result is a 'retained pixel charge'. This can affect the crystal alignment at the bottom or top of a liquid crystal cell, or even migration to the edges of a cell, depending on the resultant polarity of the parasitic charge buildup. These conditions may cause image sticking over an entire area of the screen, and in particular over those boundaries where there are distinct color changes. The severity of the resultant image sticking would - as pointed out above - vary among different brands, and depends on several factors including operating temperature, time the static image remained on, and the image pattern, contrast and brightness levels.

Title:
Image sticking measurement method for liquid crystal display device
Document Type and Number:
United States Patent 6590411

Abstract:
A method for measuring an image sticking defect in a liquid crystal display device includes the steps of grounding a liquid crystal cell, the liquid crystal cell includes an alignment layer, applying a first alternating current voltage to the liquid crystal cell, measuring a first capacitance of the liquid crystal cell, applying an electrical stress to the liquid crystal cell, measuring a second capacitance of the liquid crystal cell, and calculating a capacitance difference between the first capacitance and the second capacitance.
