Abstract

The invention is applicable to the field of televisions and provides a method and a device for dynamically adjusting backlight of a television screen, and a television. The method comprises the following steps of: acquiring a luminance parameter of current image content, and calculating a luminance value of the current image content according to the luminance parameter of the current image content; acquiring a backlight parameter value of the television screen; and comparing the backlight parameter value of the television screen with the luminance value of the current image content, and dynamically adjusting the backlight parameter value of the television screen according to a comparison result. By the method and the device, the backlight parameter value of the television screen is dynamically adjusted according to the luminance value of the transmitted image content, the function of dynamically adjusting the backlight is realized, the dynamic contrast is improved, the picture qualityof the image content is effectively improved, and the aims of energy conservation and environmental friendliness are fulfilled at the same time.

Description

technical field [0001] The invention belongs to the field of televisions, and in particular relates to a method and device for dynamically adjusting the backlight of a television screen and the television. Background technique [0002] With the rapid development of the entire TV industry, the continuous deepening of the national economy and consumption upgrades, the concepts of energy saving, power saving, and green environmental protection have become more and more popular among the people, and consumers' consumption demands and consumption quality are also constantly improving. The image screen and the backlight dynamic adjustment requirements of the TV screen are also getting higher and higher. [0003] The existing backlight dynamic adjustment method is mainly to dynamically adjust the LCD or LED backlight according to the collected ambient light. This method adjusts the backlight of the screen by collecting ambient light, which cannot effectively improve the image qual...
