The invention relates to a novel LCD (Liquid Crystal Display) double energy-saving control module, which comprises an LVDS (Low Voltage Differential Signaling) signal distribution circuit, a signal converting circuit, a signal processing circuit, a PWM (Pulse Width Modulation) pulse generation circuit and an ambient light self-adaptive circuit, wherein the LVDS (Low Voltage Differential Signaling) signal distribution circuit is connected with an LVDS signal output port; the signal converting circuit and the LVDS signal distribution circuit are connected for converting an LVDS signal into a simulation video signal; the signal processing circuit and the signal converting circuit are connected for converting the simulation video signal into direct current voltage change; the PWM (Pulse Width Modulation) pulse generation circuit and the signal processing circuit are connected for generating a PWM control signal according to the direct current voltage change; and the output of the ambient light self-adaptive circuit and the direct current voltage change are connected to the PWM (Pulse Width Modulation) pulse generation circuit through an adding circuit. The novel LCD double energy-saving control module is adaptive to LCDs with any signal source and any size, is applicable for LED (Light Emitting Diode) light sources or CCFL (Cold Cathode Fluorescent Light) light sources, and has the characteristics of good compatibility and universality, convenient organization and batch production as well as energy saving and reformation, simple structure and low cost.
Description
technical field [0001] The invention relates to a liquid crystal display, and more specifically relates to a novel LCD dual energy-saving control module. Background technique [0002] In LCD (Liquid Crystal Display) products, the backlight is displayed by CCFL (Cold Cathode Lamp) or LED (Light Emitting Diode) as the light source. In previous products, the brightness of the backlight is a constant value, that is, no matter how bright or dark the image or ambient light is, the backlight always works at the state of maximum power consumption. With the increasing market share and screen size of LCDs, the power consumption of LCDs is also increasing. Especially in the high-brightness products used in outdoor environments, the power consumption of high-brightness LCDs above 42 inches can be reduced. Up to 800W or more. Not only that, but the increase in power consumption will also lead to problems such as increasing the cost and difficulty of heat dissipation and shortening the ...
