What is TV LCD Health Screen Change?

Screen change is a term for Skyworth LCD TVs. Other brand TVs have the same function, but they are not the same.

Simply put:

1. Adjust the screen brightness according to the ambient brightness;

2. Adjust the overall screen brightness according to the overall brightness of the image;

Standard definition:

Screen change is divided into: light-sensitive screen change, scene change screen;

Light-sensitive screen change: Induction of ambient light, health is not dazzling;

Light-sensitive screen change refers to the use of the television's built-in optical sensor, through the monitoring of the brightness of the external environment to adjust the backlight lamp brightness level and power.

When an optical illuminometer is used to monitor the photoreceptor, the power used by the television changes significantly with the brightness of the external environment. When a flashlight is used to illuminate the photoreceptor, the amplitude of the change in the television screen is very large and it is automatically adjusted to Dazzling state.

Scene change: scene dynamic tracking, clear picture;

Scene change is a technology owned by Skyworth alone. It is another core of “screen change” technology. The change of TV scene is dynamic, and it is continuous. The scene screen change uses the compensation processing of the chip to automatically track the strength of the input signal and perform accurate management and control of the brightness of the backlight. When a large area of ​​bright field is encountered, the control chip will automatically adjust the brightness of the light source, reduce the brightness of the bright field, and the average brightness tends to be gentle with the increase of the bright field area, thereby improving the layering of the bright field, which can effectively alleviate Excessively dazzling; when encountering a large area of ​​dark field, the chip will reduce the brightness of the backlight, and at the same time enhance the bright field part of the picture through brightness correction, so that the black part of the picture is abnormally deep and pure, enhancing the contrast of the picture and Layering.
