Abstract
The utility model relates to a backlight module and particularly relates to a downright LED (Light Emitting Diode) backlight module capable of preventing bright bands. The downright LED backlight module comprises an LED matrix formed by a plurality of LEDs arranged in an array manner, wherein at least two rows of LEDs are arranged at the upper and lower parts of the LED matrix, at least two rows of LEDs are arranged at the left and right parts of the LED matrix, and the LEDs in the adjacent rows are staggered from one another left and right. The downright LED backlight module has the beneficial effects of being capable of avoiding the bright bands, and being beneficial to the improvement of image quality of a television.
Description
Technical field
The utility model relates to backlight module, relates in particular to a kind of direct-light type LED backlight module that prevents bright band.
Background technology
Backlight module is one of key part and component of panel of LCD.Function is well-off brightness and the light source that is evenly distributed, and makes normally show image of liquid crystal display.
LED(Light Emitting Diode, light emitting diode) backlight can be divided into straight-down negative and side-light type, and pluses and minuses are respectively arranged, and cost variance, but on the end product price mutual height then; Because ultra-thin television receives an acclaim day by day, the sales volume of side-light type LED TV is grown up can be very fast, kinder and more approachable on the price.Straight-down negative LED TV needing then to be subject to the consumers welcomed of high-order audio-visual devices.
Direct-light type LED backlight LCD TV (Direct-lit, Direct Illumination-type LED Backlight) obtains the large factory of TV and generally adopts when just beginning to deliver; Straight-down negative be the LED uniform crystal particles be configured in liquid crystal panel the rear be used as light emitting source, make backlightly can evenly be communicated to whole screen, picture detail is finer and smoother true to nature.
As shown in Figure 1, be the array arrangement figure of the light emitting diode 1 of traditional direct-light type LED backlight module, this light emitting diode 1 takes the straight line matrix to be arranged on the reflecting element 2, bright band occurs easily, affects the picture effect of TV.
