Local dimming is a technology that darkens the black areas on the screen to improve contrast. The difference between the "local dimming" version and the "non-local dimming" version is reflected not only in the hardware but also in the software. The purpose of introducing Crystal Light is to meet the needs of users who want high resolution but are on a limited budget.

The implementation of local dimming requires not only software algorithm support but also Mini LED backlight technology, so the "no local dimming" version does not have the original backlight configuration.

Bottom line : the version with local dimming offers deeper black levels and improved contrast, making a difference in visual display quality.
