Abstract
An LED backlight plate with good color mixing and light intensity balance comprises a PCB (10) and an LED light source array (20) regularly arranged on the PCB (10), wherein the LED light source array (20) includes a plurality of quadrangular units; and LED light sources with three colors are arranged on the four vertexes of each quadrangular unit in such a manner that the two LED sources with the same color are arranged diagonally. The quadrangular units of the LED light source array (20) can be selected from a rhombic structure, a quadrate structure or a square structure. The LED backlight plate facilitates white balance adjustment and light intensity comparison balance.
Description
Technical field
The utility model relates to display device, particularly is used for the LED-backlit source of LCD TV.
Background technology
LCD is passive light-emitting display device, needs module ability operate as normal backlight, and at present, most of LCD adopt cold-cathode fluorescents (CCFL) module backlight, are subjected to the restriction of the CCFL characteristics of luminescence, adopt the LCD TV of CCFL module backlight, and its color reducibility is relatively poor.
Comparatively speaking, LWD module backlight has that color reducibility is good, contrast is high, brightness is high and the fireballing advantage of light emitting control, and the LED-backlit technology that is applied to the large scale liquid crystal TV has in recent years obtained significant progress.But in the present module backlight, generally all be to adopt each one of red, green, blue LED to form a unit, this fit system, its white balance and luminous intensity balanced are relatively poor.
Summary of the invention
The utility model provides that a kind of colour mixture is good, the LED-backlit plate of luminous intensity balanced, adopts a redness to add a blueness and adds two green LED again and form a unit, white balance and the relatively poor technical problem of luminous intensity balanced in the solution prior art.
The scheme that the utility model solves the problems of the technologies described above is: design a kind of LED-backlit plate, comprise LED light emitting source array regularly arranged on pcb board and the pcb board; Described LED light emitting source array is that a plurality of quadrangles constitute, being positioned at the LED light emitting source that four LED light emitting sources on four summits of each quadrangle are three kinds of colors constitutes, wherein two homochromy LED light emitting sources are the diagonal angle layout, and a plurality of quadrangles in the described LED light emitting source array are rhombus, square or square.
The LED-backlit plate that adopts technical solutions of the utility model to make, it helps white balance adjusting and beam intensity ratio is balanced.
Description of drawings
Fig. 1 is the schematic diagram of the utility model LED-backlit plate.
The specific embodiment
In conjunction with above-mentioned description of drawings specific embodiment of the utility model.
By among Fig. 1 as can be known, this colour mixture is good, the LED-backlit plate of luminous intensity balanced, comprises LED light emitting source array 20 regularly arranged on pcb board 10 and the pcb board 10; Described LED light emitting source array 20 constitutes for a plurality of quadrangles, is positioned at the LED light emitting source that four LED light emitting sources on four summits of each quadrangle are three kinds of colors and constitutes, and wherein two homochromy LED light emitting sources are the diagonal angle and arrange.A plurality of quadrangles in the described LED light emitting source array 20 are rhombus, square or square.Principle of the present invention is: under the situation of the LED that does not consider the border, the neighbour of each LEDs has the LED of 4 other colors, 2 of every looks.With the frame of broken lines among Fig. 1 is example, there is a green LED light emitting source G at the center, 2 red LED light emitting source R and 2 blue led light emitting source B are arranged on every side, this being arranged with is beneficial to white balance adjusting and luminous intensity balanced, be described as follows: the ratio of supposing the luminosity of red, green and blue LED satisfies R:G:B=0.3:0.59:0.11, during design, distance between the LED is most important, the brightness that this distance just makes 2 R of G neighbour produce at center G place equals the luminosity of R, in like manner, the brightness that produces at center G place of the G neighbour's 2 B equals the luminosity of B.Like this,, can obtain white light at center G place according to brightness-formula Y=0.30R+0.59G+0.11B, same analysis, except that borderline LED, the LED of 4 other looks of each LEDs and vicinity produces white light in the center.The LED lamp plate of this arrangement through the mixed light effect of diffuser plate, will obtain the LED lamp plate of white balance and luminous intensity balanced.Be enough to co-relation if the luminosity ratio is discontented, luminous dutycycle or the drive current that can regulate LED satisfy with co-relation.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
