Abstract

The invention provides a system and a method for configuring an LED backlight module with high color saturation. The method comprises the following steps of: calculating a standard spectrum, wherein the standard spectrum is the spectrum of visible light transmitted by black-body radiation under a first color temperature; providing a transmission spectrum of an LED, a transmission spectrum of first fluorescent powder and a transmission spectrum of second fluorescent powder; according to the standard spectrum, adjusting the concentrations of the first fluorescent powder and the second fluorescent powder to obtain the first light mixed spectrum, and making the first light mixed spectrum closer to the standard spectrum; and making the first light mixed spectrum undergo color separation by a color filter to form a color coordinate of three primary colors, calculating an area formed by the color coordinate of three primary colors, and calculating a position of the color coordinate of the white light formed by the three primary colors. The method mainly uses the algorithms to calculate the concentrations of multiple fluorescent powder, so that after the light of the multiple fluorescent powder is mixed with the light of the LED, the backlight module with high color saturation is provided.

Description

technical field [0001] The invention relates to a light-emitting diode backlight module, in particular to a configuration system and method for a light-emitting diode backlight module with high color saturation. Background technique [0002] Light Emitting Diode (LED for short) is an electronic component that can convert electrical energy into light energy, and also has the characteristics of a diode. Generally, when DC power is supplied, the LEDs will emit light steadily, but if AC power is connected, the LEDs will flash, and the frequency of the flashing depends on the frequency of the input AC power. The light-emitting principle of light-emitting diodes is to apply an external voltage to make electrons and holes combine in the semiconductor to release energy in the form of light. [0003] At present, the composition of the light emitting diode chip mainly includes group III arsenide, group III phosphide, group III nitride or semiconductor compound of group II-VI. With t...
