Problems solved by technology

The energy efficiency index mainly depends on the power consumption of the whole machine. The display screen in the LED TV is passively illuminated by lighting the LED backlight. Among them, the power consumption of the whole LED TV machine mainly depends on the LED display backlight. Currently, the LED TV on the market After the TV is turned on, the backlight is always at the highest brightness, which will inevitably increase the power consumption of the whole machine and reduce the energy efficiency index.
On the other hand, when the ambient light is very dark, the LED display with too high brightness will be dazzling, and when the image is very dark, the LED display with too high brightness will reduce the contrast and layering of the image
Therefore, if the LED display is always at the highest brightness, it will not only reduce the comfort of the user when using the TV, but also increase the power consumption of the LED TV and reduce the energy efficiency index.

Abstract

The invention relates to a method for improving an energy efficiency index of an LED (light-emitting diode) display screen. The method specifically comprises the following steps of: acquiring an environment luminance brightness value and / or an image brightness value and carrying out operation on the environment luminance brightness value and / or the image brightness value to obtain a target backlight value of the LED display screen; and regulating the brightness of backlight of the LED display screen according to the target backlight value. Due to the adoption of the method, the effect that the brightness of the backlight of the LED display screen is regulated according to the environment luminance brightness or the image brightness is realized and the power consumption of the LED display screen is reduced, so that the energy efficiency index of the LED display screen is improved.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method for improving the energy efficiency index of an LED display screen and the LED display screen. Background technique [0002] With the promotion of energy saving and environmental protection, high energy efficiency index has become the primary standard of LED TV performance. The energy efficiency index mainly depends on the power consumption of the whole machine. The display screen in the LED TV is passively illuminated by lighting the LED backlight. Among them, the power consumption of the whole LED TV machine mainly depends on the LED display backlight. Currently, the LED TV on the market After the TV is turned on, the backlight is always at the highest brightness, which will inevitably increase the power consumption of the whole machine and reduce the energy efficiency index. On the other hand, when the ambient light is very dark, the LED display with too high bri...
