Description
Technical field
The invention belongs to display screen manufacturing technology field, particularly relate to a kind of method increasing display color gamut of LED display screen.
Background technology
Existing LED television adopts the principle of three primary colours, and the principle of three primary colours is the basis of color TV technology.According to the visual characteristic of human eye, reproduced image in television equipment. do not require the spectral component of reappearing former scene reflections or transmitted light completely, only need imitate human eye three kinds of pyramidal cells. (three kinds of primary colours must be separate to select three kinds of primary colours, any one primary colours all can not be obtained by other two kinds of mix of basic colors). they are organized a performance by different proportion, the most color of occurring in nature can be obtained.There are three kinds of monochromatic light of these characteristics primary lights. three kinds of colors are three primary colours: namely red, green, blue.In color TV, represent red, green, blue with R, G, B respectively.The wavelength of the selected red primary of International Commission on Illumination (CIE) is 700nm, and the wavelength of green primary is 546.1nm, and the wavelength of blue primary is 435.88nm.The brightness of the colour that three primary colours light is mixed to get mutually equals three kinds of luminance primary sums. and this color mixture is called additive color mixture.Circular for equicohesive for three beams red, green, blue monochromatic light is projected in white screen simultaneously, there will be the some circle of three primary colours.
When the LED television that prior art provides adopts the principle of three primary colours to carry out image display, the constrained color gamut of display, display effect is not good.
Summary of the invention
The invention provides a kind of method increasing display color gamut of LED display screen, when the LED television that being intended to solve prior art provides adopts the principle of three primary colours to carry out image display, the constrained color gamut of display, the problem that display effect is not good.
The object of the present invention is to provide a kind of method increasing display color gamut of LED display screen, the method comprises the following steps:
Determine the scope of three look wavelength;
Each pixel adds the orange-yellow LED of wavelength an about 580nm;
DVI recalculates the data producing red greenish-yellow blue four looks;
Give red greenish-yellow indigo plant each one group of data-signal, and the data-signal of four looks is disperseed to show to yellowish green champac four colored lights.
Further, the LED display that the method provides is red, green, blue and yellow four-color LED display.
Further, the LED display not arrangement position of restrict colors and the LED number of single color that provide of the method.
Further, the color region that the LED display that the method provides can show is quadrilateral, comparatively adopts the LED display of the principle of three primary colours to increase the display colour gamut of 10%.
The method of increase display color gamut of LED display screen provided by the invention, on the basis of scope determining three look wavelength, the orange-yellow LED of wavelength an about 580nm is added at each pixel, then the data producing red greenish-yellow blue four looks are recalculated by DVI, finally give red greenish-yellow indigo plant each one group of data-signal, and the data-signal of four looks is disperseed to show to yellowish green champac four colored lights; The method adds the orange-yellow LED that a wavelength is about 580nm, the color region that LED display can be shown is quadrilateral, the LED display of the principle of three primary colours is comparatively adopted to increase the display colour gamut of 10%, drastically increase the display effect of LED display, produce and use cost lower, there is stronger propagation and employment and be worth.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of the method for the increase display color gamut of LED display screen that the embodiment of the present invention provides;
Fig. 2 is the color region coordinate diagram of the red greenish-yellow blue four look LED display that the embodiment of the present invention provides.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and be not used in restriction invention.
Fig. 1 shows the flow process of the method for the increase display color gamut of LED display screen that the embodiment of the present invention provides.
The method comprises the following steps:
In step S101, determine the scope of three look wavelength;
In step s 102, each pixel adds the orange-yellow LED of wavelength an about 580nm;
In step s 103, DVI recalculates the data producing red greenish-yellow blue four looks;
In step S104, give red greenish-yellow indigo plant each one group of data-signal, and the data-signal of four looks is disperseed to show to yellowish green champac four colored lights.
In embodiments of the present invention, the LED display that the method provides is red, green, blue and yellow four-color LED display.
In embodiments of the present invention, the LED display not arrangement position of restrict colors and the LED number of single color that provide of the method.
In embodiments of the present invention, the color region that the LED display that the method provides can show is quadrilateral, comparatively adopts the LED display of the principle of three primary colours to increase the display colour gamut of 10%.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
The red greenish-yellow blue four look LED display that the method provides, on the basis determining three look wavelength coverages, add the orange-yellow LED that a wavelength is about 580nm, the data producing red greenish-yellow blue four looks are recalculated by DVI, and then be supplied to each one group of data-signal of red greenish-yellow indigo plant, show the data scatter of four looks to yellowish green champac four colored lights.
As shown in Figure 2, three primary colours colour gamut (triangle ABC) is the gamut range of former three look technology, the colour gamut that the colour gamut (triangle ACD) increased increases for increasing the orange-yellow LED of 580nm, quadrilateral ABCD is the display colour gamut of four look display screens.
The method of the increase display color gamut of LED display screen that the embodiment of the present invention provides, on the basis of scope determining three look wavelength, the orange-yellow LED of wavelength an about 580nm is added at each pixel, then the data producing red greenish-yellow blue four looks are recalculated by DVI, finally give red greenish-yellow indigo plant each one group of data-signal, and the data-signal of four looks is disperseed to show to yellowish green champac four colored lights; The method adds the orange-yellow LED that a wavelength is about 580nm, the color region that LED display can be shown is quadrilateral, the LED display of the principle of three primary colours is comparatively adopted to increase the display colour gamut of 10%, drastically increase the display effect of LED display, produce and use cost lower, there is stronger propagation and employment and be worth.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
