Recognize and avoid clouding effects
Have you recently seen bright spots on the LED screen? Then it is the clouding effect. Pressure relief and cooling can help.
The clouding effect occurs when the device overheats
The clouding effect is a problem that occurs with LCD and LED TVs. The four corners of the device are brighter than other places. It looks as if the surfaces are being illuminated with a flashlight or as if there are bright "clouds" on the screen spread. So the screen is lit differently.
The lighting problem is related to the technology of the device. Between the surface and the backlight of the device there are liquid crystals which, depending on the electrical impulses, form a assume different formation and the backlight accordingly differently towards the front let through. Pressure and heat have an influence on the behavior of the crystals and create an uneven picture, as they trigger unwanted reactions of the crystals.
The effect of overheating or too much pressure occurs if the manufacturer installs too little ventilation. In addition, a room that is too warm, proximity to a heater or incorrect transport promote overheating.
Prevent the clouds and remove them
To prevent the effect, make sure that it is transported appropriately. The liquid crystals are only attached to the corners and bend when the television is lying down. On uneven roads, this leads to long-term deformation of the device. Put your TV in the car.
If you notice a clouding effect on your TV set, make sure that the TV is not in the immediate vicinity of the heater. A cooler room temperature also avoids the problem.
If you, too, are the proud owner of an LCD TV, maybe you too ...
With some devices, it is sufficient to open the screw connection of the panel, thus ensuring better ventilation and minimizing the pressure caused by any deformation of the frame. However, the screw connection must not be opened completely. This tip can also be used to prevent banding - stripes instead of spots on the surface of the image.
Rub lightly over the affected area with a lint-free cloth. This distributes the pressure better and the effect is less pronounced.
Provide additional cooling for the television set. For example, you can attach additional case fans to the ventilation slots on the TV. This allows additional cool air to enter the device. In most cases this eliminates the clouding effect. A fan directed towards the ventilation slots on the TV can also help.
If these measures do not help, it helps to illuminate the room, because the clouding effect is annoying in darkened rooms and with dark film sequences. The clouding effect is still there, but appears less intense.
Not every LCD TV has this problem. Many model series no longer have the problem as manufacturers adapt production. You can see how vulnerable the device is from user reviews on the Internet. If the problem occurs, coolness and pressure relief will help.
