Abstract
The utility model discloses a LCD display system based on three primary colors time schedule control, it includes the array light source to and set up at anterior all smooth ware and the monochromatic LCD screen of array light source, the array light source leads to and monochromatic LCD screen is connected with a time sequence control circuit respectively, the array light source includes a plurality of LED banks of evenly arranging in proper order on the coplanar, the LED banks comprises blue light LED lamp cluster, ruddiness LED lamp cluster and green glow LED lamp cluster NULL. This display system has with low costs, hi -lite, the high characteristics of resolution.
Description
Technical field
The utility model is related to a kind of LCD display system based on three primary colours SECO.
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 pass through three
Other two kinds of primary colours are fully opaque by the one of which primary colours in primary colours, therefore can only pass through 1/3rd in theory
Light, if considering further that the purity of color, transmitance is just lower.And monochrome mono- pixel cell only one of which picture of LCD
Vegetarian refreshments, and all of light can pass through 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, three times of high resolution.So, there is great reality meaning with single color LCD screen display coloured image
Justice.
Utility model content
The purpose of this utility model is to provide a kind of LCD display system based on three primary colours SECO, and it has cost
Low, high brightness, differentiate high feature.
For solving above-mentioned technical problem, the utility model provides a kind of LCD display system based on three primary colours SECO,
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 leads to and single color LCD
Screen is connected with a sequential control circuit respectively；Array light source includes some LED light groups being evenly spaced in successively on same plane,
By blue LED lamp string, red LED lamp string and green light LED lamp string is alternately arranged forms for LED light group.
Further, all light device is condenser and is arranged on the Fresnel Lenses on front side of condenser.
Further, single color LCD screen is low temperature polycrystalline silicon liquid crystal panel or high temperature polysilicon liquid crystal panel.
The beneficial effects of the utility model are：The array light source of the application is made up of three-primary color LED lamp, by by three primary colours
The array light source of LED composition and monochromatic LCD composition imaging system, control the three primary colours of array light source by sequential control circuit
The closing of LED is superimposed as coloured image, obtains color video further, this display system improve display brightness and resolution
While rate, also reduce cost.And, with not needing light-combining prism, same array light source adopts all light to this display
Device directly light shines single color LCD screen.
Brief description
Fig. 1 is the structural representation of one embodiment of the utility model；
Fig. 2 is the structural representation of the array light source of one embodiment of the utility model.
Wherein：1st, sequential control circuit；2nd, array light source；3rd, condenser；4th, Fresnel Lenses；5th, single color LCD screen.
Specific embodiment
Below specific embodiment of the present utility model is described, understands in order to those skilled in the art
The utility model, the common skill it should be apparent that the utility model is not limited to the scope of specific embodiment, to the art
For art personnel, as long as various change is in the spirit and scope of the present utility model of appended claim restriction and determination,
These changes are it will be apparent that all utilize the innovation and creation of the utility model design all in the row of protection.
LCD display system based on three primary colours SECO as shown in Figure 1, including array light source 2, is arranged on array light
All light device of source 2 front portion, 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 light group on face, by blue LED lamp string, red LED lamp string and green light LED lamp string is alternately arranged forms for LED light group.
Wherein, above-mentioned all light device is condenser 3 and the Fresnel Lenses 4 being arranged on front side of condenser, and single color LCD screen 5 is
Low temperature polycrystalline silicon liquid crystal panel or high temperature polysilicon liquid crystal panel.
The operation principle of this display system is：Sequential control circuit 1 is first divided into red bluish-green three primary colours a width colour picture
Three width pictures, red pictorial information is sent to single color LCD screen 5, single color LCD screen 5 will appear from black white image, image
White clear part represent the RED sector of artwork piece, sequential control circuit 1 lights the red LED lamp in backlight simultaneously
Group, the ruddiness that red LED lamp set sends, through backlight, is irradiated to above single color LCD screen 5, presents picture RED sector.With
The green portion of picture and blue portion timesharing it is also possible to be presented on above single color LCD screen 5, the vision due to human eye is stopped by reason
Stay phenomenon, as long as the time is enough short, a width will be constituted by the three primary colours monochrome image that different time is presented on single color LCD screen 5 color
Chromatic graph piece, when the refreshing frequency of single color LCD screen 5 is more than 120Hz, display will present the video pictures of smoothness.
