Embodiment Construction

[0020] refer to figure 1 , a kind of TV energy efficiency control method that the present invention improves image quality effect, at first, set a plurality of backlight cut-off values, and each backlight cut-off value is associated with a brightness range; Then, when playing moving pictures, according to the average Adjust the brightness of the TV backlight according to the cut-off value of the backlight corresponding to the brightness.

[0021] In this way, in this embodiment, when the TV is playing a moving picture, the backlight brightness can be automatically adjusted according to the preset correspondence between the average brightness of the picture and the backlight brightness, so that the backlight is more bright when the TV is playing a high-brightness picture. Bright; when playing a dark picture, the backlight is darker, which increases the contrast and reduces the damage of the energy efficiency index to the image quality.

[0022] Moreover, in this embodiment, th...

Abstract

The invention proposes a television energy efficiency control method for improving the image quality effect. The method comprises the steps: setting a plurality of backlight boundary values, wherein each backlight boundary value is associated with a brightness interval; during the playing of an active picture, adjusting the backlight brightness of the television according to the backlight boundaryvalue corresponding to the average brightness of the television picture. According to the television energy efficiency control method for improving the image quality effect provided by the invention,when the television plays the active picture, the backlight brightness can be automatically adjusted according to the preset corresponding relationship between the average brightness of the picture and the backlight brightness, so that the backlight is brighter when the television plays a high-brightness picture; when a dark picture is played, the backlight is darker, so the contrast ratio is increased, and the damage of the energy efficiency index to the picture quality is reduced. According to the invention, the purposes of reducing the dynamic power and improving the energy efficiency index are achieved.

Description

technical field [0001] The invention relates to the technical field of energy-saving televisions, in particular to a television energy efficiency control method for improving image quality effects. Background technique [0002] The existing energy efficiency improvement technology method is: when the TV is playing a static picture, the brightness of the TV’s backlight remains unchanged; when the TV is playing a dynamic picture, the TV can recognize this playback state and automatically reduce the backlight brightness through a software algorithm, thereby reducing Dynamic power consumption, improve the energy efficiency index of the TV. [0003] At present, the brightness adjustment of the backlight of the TV adopts pulse width modulation, that is, PWM dimming. The specific method is to give a PWM control signal to the backlight control chip of the TV: when the duty cycle of the PWM is 100%, the brightness of the backlight of the TV is the highest; when the duty cycle of the...
