Description
Technical field
The present invention relates to a kind of LCD display system based on three primary colours sequencing contro and the display side of this display system
Method.
Background technology
At present, in order to realize colored display, each pixel cell of single color LCD screen is by red bluish-green three independences
Pixel forms, and structure is complex, is difficult to improve further picture element density, and meanwhile, each pixel can only be by three
Other two kinds of primary colours are fully opaque by the one of which primary colours in primary colours, the most in theory can only be through 1/3rd
Light, if considering further that the purity of color, transmitance is the lowest.And monochrome mono-pixel cell only one of which picture of LCD
Vegetarian refreshments, and all of light can be by this pixel, the light transmittance ratio of the single color LCD screen of thus like technical standard
Colored single color LCD screen is high four times, and resolution is three times higher.So, there is great reality meaning with single color LCD screen display coloured image
Justice.
Summary of the invention
It is an object of the invention to provide a kind of LCD display system based on three primary colours sequencing contro and this display system

For solving above-mentioned technical problem, the present invention provides a kind of LCD display system based on three primary colours sequencing contro, including
Array light source, and it is arranged on the anterior all light device of array light source and single color LCD screen；Array light source is logical and single color LCD screen divides
It is not connected with a sequential control circuit；Array light source includes some LED groups being evenly spaced in successively on same plane, described
LED group is by blue LED lamp string, red LED lamp string and green light LED lamp string is alternately arranged forms.
Further, all light device is condenser lens and is arranged on the Fresnel Lenses on front side of condenser lens.
Further, single color LCD screen is low temperature polycrystalline silicon liquid crystal panel or high temperature polysilicon liquid crystal panel.
Present invention also offers the display packing of a kind of LCD display system based on three primary colours sequencing contro, the method has
Body includes: utilizes sequence circuit that the colour picture received is divided into three width primary colours pictures, will be located in the different face of same an array
The light of the LED string of color is irradiated to on a piece of single color LCD screen by same all light device chronologically, simultaneously at single color LCD screen
The color that upper input picture is corresponding；Recycling human eye vision short stay phenomenon synthesizes the image that a width is complete, obtains color and regards
Frequently.
Further, the sequence of light of the LED string of different colours and the tristimulus image timing synchronization of single color LCD screen.
Further, the time interval that the light of the LED string of different colours shows is less than or equal to 10 microseconds.
The invention have the benefit that the array light source of this LCD display system is made up of three-primary color LED lamp, by by three
The array light source of primary-color LED lamp composition forms imaging system with monochromatic LCD, is controlled the three of array light source by sequential control circuit
The closedown of primary-color LED lamp is superimposed as coloured image, obtains color video further, this display system improve display brightness and
While resolution, also reduce cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention；
Fig. 2 is the structural representation of the array light source of one embodiment of the invention.
Wherein: 1, sequential control circuit；2, array light source；3, condenser lens；4, Fresnel Lenses；5, single color LCD screen.
Detailed description of the invention
Below the detailed description of the invention of the present invention is described, in order to those skilled in the art understand this
Bright, it should be apparent that the invention is not restricted to the scope of detailed description of the invention, from the point of view of those skilled in the art,
As long as various changes limit and in the spirit and scope of the present invention that determine, these changes are aobvious and easy in appended claim
Seeing, all utilize the innovation and creation of present inventive concept all at the row of protection.
LCD display system based on three primary colours sequencing contro as shown in Figure 1, including array light source 2, is arranged on array light
All light device of front portion, source 2, and it is disposed side by side on all light device and the single color LCD screen 5 of array light source 2 front portion.Array light source 2 leads to
It is connected with a sequential control circuit 1 respectively with single color LCD screen 5；Array light source 2 include some be evenly spaced in successively same flat
LED group on face, LED group is by blue LED lamp string, red LED lamp string and green light LED lamp string is alternately arranged forms.
Wherein, above-mentioned all light device is condenser lens 3 and is arranged on the Fresnel Lenses 4 on front side of condenser lens, and single color LCD screen 5 is
Low temperature polycrystalline silicon liquid crystal panel or high temperature polysilicon liquid crystal panel.
Further, the area of the array of source 2 in the application does not has strict restriction, does not has the area page of single color LCD screen 5
There is strict restriction, throwing can be improved by increasing the area of array of source 2 and single color LCD screen 5 in actual production process
The brightness of shadow machine and resolution.
Additionally, present invention also provides the display packing of a kind of LCD display system based on three primary colours sequencing contro, the party
Method specifically includes: utilizes 1 colour picture received of sequence circuit to be divided into three width primary colours pictures, will be located in same an array not
