Technical field
The utility model belongs to technical field of flat panel display, relates in particular to a kind of led array that is applied to LED in the LCDs (Light Emitting Diode, light emitting diode) module backlight.
Background technology
Nowadays, LCDs has been widely used in the electronic equipments such as television set, computer, mobile phone, owing to have high image quality, zero radiation, and advantage such as low power consuming and moulding are light and handy, LCDs is just received by increasing user and likes.LCDs is passive emitting components, itself can not self-luminous, so must provide light source for it in backlight or preceding smooth mode.Now, the module backlight that most of LCDs all adopt CCFL (Cold Cathode Fluorescernt Lamp, CCFL) to form, the then corresponding usefulness of LED-backlit module is less.The LED-backlit module is compared with CCFL module backlight, has the brightness height, contrast height, advantage such as color reducibility is good.
LED-backlit is divided into again that single-primary-color LED is backlight, dual base color LED-backlit and three-primary color LED are backlight.Wherein, three-primary color LED is backlight promptly to use the LED of red (R), green (G), blue (B) these three kinds of colors because use primitive colours LED, therefore can obtain better color saturation.Existing three-primary color LED implementation backlight generally adopts the bar shaped array, as shown in Figure 1, the LED of same color constitutes a bar shaped group, comprises bar shaped group R, bar shaped group G and bar shaped group B, and the bar shaped group of some different colours forms a bar-shaped LED array according to R, G, B order repeated arrangement.But existing bar-shaped LED array mixed light poor effect, it forms red, green, blue strip light belt easily, therefore can't obtain the saturated uniform white light of color.
In summary, the led array in described existing LED-backlit source obviously exists inconvenience and defective, so be necessary to be improved on reality is used.
The utility model content
At above-mentioned defective, the purpose of this utility model is to provide a kind of led array that is applied to LED-backlit module in the LCDs, and it has good mixed light effect, and then it is good to obtain color saturation, the even brightness white light.
To achieve these goals, the utility model provides a kind of led array of LED-backlit module, this led array is applied to LCDs, described led array comprises a substrate, described substrate is provided with a plurality of red LED, green LED and blue led, described red LED, green LED and blue led space are staggered, and each described LED does not have adjacent homochromy LED in the horizontal direction with on the vertical direction.
According to led array of the present utility model, the number ratio of described red LED, green LED and blue led is 1:2:1.
According to led array of the present utility model, described led array is arranged in the direct-light type LED backlight module.
According to led array of the present utility model, comprise several LED unit groups in the described led array, described LED unit group is by 2
nIndividual LED constitutes, and described n is the natural number more than or equal to 2.
According to led array of the present utility model, described LED unit group is made of 4 LED.
According to led array of the present utility model, described LED unit group is made of 9 LED.
According to led array of the present utility model, described LED unit group is made of 16 LED.
According to led array of the present utility model, described some LED unit group is evenly arranged into described led array.
According to led array of the present utility model, described led array is placed M*N LED unit group that is matrix type according to the size and the Aspect Ratio of LCDs, and described M and N are the natural number more than or equal to 1.
Red LED, green LED and blue led space are staggered in the utility model led array, and the LED of every kind of color does not have adjacent homochromy LED in the horizontal direction with on the vertical direction.Whereby, the utility model led array has good mixed light effect, and then it is good to obtain color saturation, the even brightness white light.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Basic thought of the present utility model is: a kind of led array that is applied to the LED-backlit module of LCDs is provided, described led array comprises a substrate, described substrate is provided with a plurality of red LED, green LED and blue led, the LED space of these three primary colours is staggered, and each LED does not have adjacent color LED of the same race in the horizontal direction with on the vertical direction, this led array has good mixed light effect, can obtain the saturated and uniform white light of color in the zone.
Fig. 2 shows first exemplary construction of the led array of the utility model LED-backlit module, and this led array preferably is arranged in the direct-light type LED backlight module.Described led array is arranged at (not shown) on the substrate, this substrate can be made by resin material, and led array is made up of 16 red LED (R), green LED (G) and blue led (B), in fact the LED number in the utility model led array is also unrestricted, and it can be decided fully as required.Crucial is, described red LED (R), green LED (G) and blue led (B) space are staggered, promptly be gridiron pattern and arrange shape, and each LED does not have adjacent homochromy LED in the horizontal direction with on the vertical direction, for example each green LED (G) is only understood adjacent red LED (R) or blue led (B) in the horizontal direction with on the vertical direction among Fig. 2, and will not adjacent homochromy green LED (G).
Because in Red Green Blue, the most responsive in the human vision is green, therefore the utility model preferably in the led array number ratio of red LED, green LED and blue led be set to 1:2:1, it can make the image analysis better effects if, color is more bright-coloured lively.Among 16 LED of led array as shown in Figure 2, have 8 to be green LED (G), and red LED (R) and blue led (B) respectively are 4.
Fig. 3 shows second exemplary construction of the utility model led array, comprises several LED unit groups 10 in the described led array, and each LED unit group 10 is made of 16 LED among Fig. 2, and described some LED unit group 10 is evenly arranged into led array.Be more preferably, described led array is placed the individual LED unit group 10 that is matrix type of M (OK) * N (row) according to the size and the Aspect Ratio of LCDs, and described M and N are the natural number more than or equal to 1.Every row is placed 4 LED unit groups 10 (being M=4) in the led array shown in Figure 3, and every row are placed 3 LED unit groups (being N=3).
In fact the LED unit group in the led array can be by 2
nIndividual LED constitutes, and described n is the natural number more than or equal to 2.Second kind of LED unit group 20 for example shown in Figure 4 comprises 2
3=9 LED, the third LED unit group 30 shown in Figure 5 then comprises 2
2=4 LED.
In sum, red LED, green LED and blue led space are staggered in the utility model led array, and the LED of every kind of color does not have adjacent homochromy LED in the horizontal direction with on the vertical direction.Whereby, the utility model led array has good mixed light effect, and then it is good to obtain color saturation, the even brightness white light.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
