Abstract

The invention discloses a method of controlling dynamic backlight, particularly a more reasonable method of controlling the brightness of 0D (zero-dimensional) dynamic backlight according to the humanvision. The method of controlling dynamic backlight comprises the steps of receiving the input first image signal, receiving the input ambient light detection signal, processing the received input signal, processing the first image signal and the ambient light detection signal and calculating the generated backlight signal. The invention also discloses a device of controlling the dynamic backlight.

Description

technical field [0001] The invention relates to a dynamic backlight control method, in particular to a dynamic backlight control method based on ambient light and image content; the invention also relates to a dynamic backlight control device. Background technique [0002] Dynamic backlight technology is a method, which is a kind of intelligent control. These controls can fully display its bright and vivid colors when the product is displayed in the store. Consumers will also be comfortable and not easy to feel tired when watching at home. It can also save energy. Because in the process of dynamically adjusting the backlight, the power consumption will drop, if the backlight is always on. The light source is constant, and its power consumption is very large. [0003] Whether it is natural light or dynamic backlight, the goal is to make consumers watch TV healthier and more environmentally friendly. The technology of natural light mainly restores polarized light to circula...
