Abstract
The utility model discloses an LED array structure of an LED backlight module, which aims to achieve better color mixing effect, higher color saturation and uniform white light of the LED array. According to the technical scheme, the LED array structure of the LED backlight module comprises LED array groups arranged in an LCD screen, and is characterized in that the LED array structure consists of a plurality of LED array groups, and each LED array group includes LEDs arranged in oblique lines. Compared with the prior art, the LED array structure having LEDs arranged in oblique lines has better light mixing effect, and can generate white light with better uniformity through a diffusion plate, a diffusion film and a brightness enhancement film.
Description
Technical field
The utility model relates to a kind of LED-backlit module, especially a kind of array of source structure that is used for the LED-backlit module of LCD.
Background technology
Present LCDs all is to provide light source by passive emitting components for LCDs, and LCDs itself can not self-luminous, the module backlight that present most LCDs all adopts cold cathode fluorescent tube to form, the application of LED-backlit module is less, the LED-backlit module brightness height of having compared with cold cathode fluorescent tube module backlight, the contrast height, advantages such as color reducibility is good, it is backlight that LED-backlit is divided into single-primary-color LED again, the dual base color LED-backlit, three-primary color LED is backlight, wherein three-primary color LED is backlight because use primary colors red, green, the reason of blue LED lamp, can obtain better color saturation, but be to adopt bar shaped to arrange (as shown in Figure 1) generally by the implementation of cognition, but bar shaped is arranged led array and is existed mixed light inhomogeneous, form RGB strip light belt easily, and then have influence on the brightness of display screen already.
Summary of the invention
The utility model purpose provides a kind of led array structure of LED-backlit module, and the problem that solve is to make led array reach mixed light effect preferably, the saturated and uniform white light of color.
The utility model is by the following technical solutions: a kind of led array structure of LED-backlit module, comprise the led array group, described led array group is used in the LCDs, it is characterized in that: described led array structure is made of a plurality of led array groups, and described single led array group is made of the array structure that LED arranges with oblique line.
Led array structure of the present utility model is made up of a plurality of led array groups on a plurality of in the plane row and columns.
Led array group of the present utility model is made up of the red, green, blue three-primary color LED.
Led array group of the present utility model is rearranged with oblique line by the LED of red, green, blue three primary colours respectively.
The utility model compared with prior art, the array format that adopts the LED oblique line to arrange makes the mixed light better effects if, through diffuser plate, diffusion sheet and blast sheet can obtain the better white light of uniformity later.
Description of drawings
Fig. 1 is the LED bar shaped structure arranged schematic diagram of prior art.
Fig. 2 is the structural representation of the single led array of the utility model.
Fig. 3 is the structural representation of led array structure of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, structural representation for the single led array of the utility model, described led array is made of R (red), G (green), B (indigo plant) three primary colours, described R, G, the B three primary colours constitute with the oblique line arrangement mode respectively, and formation is horizontal, vertical and 45 degree oblique angles all constitute R, G, the B three primary colours are arranged, according to putting in order of RGB, constitute the led array structure that constitutes with many groups led array group.
As shown in Figure 3, be the structural representation of led array structure of the present utility model, the led array of arranging by oblique line is divided into some groups, can be according to screen size, Aspect Ratio is divided into level plural number a and organizes vertical b group, suppose a=4, b=3, then as shown in Figure 3, described each led array group has a kind of oblique line aligning method, level or vertical adjacent two groups different, described per 4 groups of adjacent led array group intersections must have the RGB three primary colours, have a kind of color to repeat simultaneously.
Led array structure of the present utility model can reach the LED-backlit module better mixed light effect, obtains the saturated and uniform white light of color in the zone.
Claims (4)
