Abstract
The utility model discloses an LED backlight source device. An LED array is divided into two rows which are staggered, so that the LED array is arranged on side surfaces of a light guide plate; a light reflection plate is arranged beside and under the LED array and the light guide plate; a brightness enhancing plate and an atomization plate are arranged on the light guide plate respectively; and the LED backlight source device is formed. The LED backlight source device can adopt lower-power LEDs arranged in two rows, so that a large-size, high-brightness and side-light type LED backlight liquid crystal device can be realized.
Description
Technical field
The utility model relates to a kind of backlight display device, particularly a kind of LED-backlit source apparatus.
Background technology
Present stage, liquid crystal indicator has been widely used in the individual consumer's goods such as notebook computer, computer monitor, TV because in light weight, advantages such as volume is little, little power consumption, radiation is low, quality is good are arranged.Because LCD panel itself does not have the characteristics of luminescence, therefore must on the LCD panel, add a light emitting source, can reach display effect, backlight source module promptly provides the optical module of LCD display back light.
The LCD backlight source module can use light emitting diode (LED), cold-cathode fluorescence lamp (CCFL), external electrode fluorescent lamp (EFFL) etc. as light source.
The backlight of giant-screen LCD main flow remains CCFL on the market, but along with development of semiconductor, the particularly appearance of high-power LED chip, LED brightness and efficient have had significant raising, make the LED-backlit source more and more be applied to LCD backlight in.Utilizing led light source is that panel backlight has a lot of advantages as LCD panel backlight than with common CCFL.Wherein the most tangible improvement is the expansion of colour gamut.Use LED-backlit to have broader colour gamut, realize more gorgeous color.But also can realize dynamically controlling the RGB mixed light, and between 9600K and 6500K, adjust white balance, and can sacrificing luminance and contrast.
General side light type LED back light liquid-crystal apparatus all is to adopt a row LED to be placed on the side of LGP basically at present, by LGP photoconduction is gone out.If the size of liquid-crystal apparatus is bigger, the requirement of brightness than higher, is just needed to strengthen the electric current on the LED, perhaps change more high-power LED and solve problem.This patent provides a kind of new solution, can use the LED of smaller power, realizes large scale, high brightness side light type LED back light liquid-crystal apparatus.
Summary of the invention
The purpose of this utility model is to use low-power LED, realizes large scale, high brightness side light type LED back light source liquid-crystal apparatus.
The utility model is achieved through the following technical solutions:
Led array divides two rows to be staggeredly placed into the side that led array is arranged in LGP, reflector the side of led array and LGP and below, blast plate and pulverizer plate be placed on respectively LGP above, form the LED-backlit source apparatus.
The lamp bar divides two dischargings to put parallel placement or be staggeredly placed.
The thickness of its LGP is the height of two row LED.
The utility model can use the LED of smaller power by above scheme, and double placement can realize large scale, high brightness side light type LED back light liquid-crystal apparatus.
Description of drawings
Fig. 1 back light source system structure chart.
The original LED layout of Fig. 2 LED-backlit module.
Fig. 3 LED-backlit module improves back LED layout.
Fig. 4 light guide plate changes.
The specific embodiment
Come the utility model is done further detailed explanation below in conjunction with accompanying drawing:
Shown in accompanying drawing, led array divides two rows to be staggeredly placed into the side that led array 1 is arranged in LGP 2, reflector 3 the side of led array and LGP and below, blast plate 5 and pulverizer plate 4 be placed on respectively LGP 2 above, form the LED-backlit source apparatus.
The lamp bar divides two dischargings to put parallel placement or be staggeredly placed.The thickness of its LGP is the height of two row LED.
The unitary construction of whole device is identical with traditional side-light type structure, mainly comprises LED lamp bar/fluorescent tube, reflector, LGP, diffuser plate and prism plate.In traditional side-light type structure, the thickness h 2 of the LGP among Fig. 4 basically with Fig. 1 in the height h1 of LED basic identical.In this patent, with LED according to the mode among Fig. 3 carry out double side by side/be staggered, the height of its LED is H1 as shown in Figure 3, then the thickness of LGP should adapt to the height of LED.Be that H2 and the H1 among Fig. 3 among Fig. 4 is basic identical.
By above scheme, can use the LED of smaller power, double placement can realize large scale, high brightness side light type LED back light liquid-crystal apparatus.
Claims (3)
1. LED-backlit source apparatus, it is characterized in that: led array divides two rows to be staggeredly placed into the side that led array (1) is arranged in LGP (2), reflector (3) the side of led array and LGP and below, blast plate (5) and pulverizer plate (4) be placed on respectively LGP (2) above, form the LED-backlit source apparatus.
