Abstract
The invention relates to a LCD backlight source, including a lateral framework, a bottom framework, a light source array arranged on the bottom framework, an optical model arranged on the top and a bottom plate arranged on the internal side surface of the lateral framework and the bottom framework. The included angle between the internal side surface of the lateral framework and the internal side surface of the bottom framework is an acute angle; the external shape pf the internal side surface of the lateral framework is a fold line or an arc line; the bottom plate arranged on the lateral framework is corresponding to the shaped of the internal side surface; the bottom plate arranged on the bottom framework is provided with an opening in the corresponding position to the light source array so as to make the light source array out of the bottom plate. The invention changes the internal side surface of the lateral framework in the prior technology into a non-inclined plane structure, thus forming an acute angle with the internal side surface of the bottom framework, so that the invention can reduce or eliminate color spot and light shadow produced on surrounding frames of the liquid crystal panel backlight source due to the optical reflection superimposed effect and further increase the display quality.
Description
Technical field
The present invention relates to a kind of backlight, relate in particular to a kind of framed structure that is used for the backlight of liquid crystal panel, belong to the structure designing technique of liquid crystal panel backlight.
Background technology
Available liquid crystal panel backlight as shown in Figure 1, comprising: body side frame 1, bottom framework 5, array of source 2, the anti-plate 3 in the end and optical mode material 4.Wherein, anti-plate 3 is laid on the inner surface of body side frame 1 and bottom framework 5 at the end, is used to reflect the light that is sent by array of source 2, to form required illuminating effect.
The defective of prior art is: the inner surface of body side frame 1 is the plane inclination structure with respect to bottom framework 5, the light that makes the anti-plate 3 in the end on the inner surface be laid in body side frame 1 array of source 2 can be sent reflex to optical mode material 4 around form color spot and lamp shadow, influence display effect.Especially when the light source in the array of source 2 is monochromatic source, Dan Se light emitting diode (LED) light source for example, after the mutual arrangement of the light that the different colours monochromatic source is sent is applied reflection, thus because mixed light tangible color spot of inhomogeneous easier formation and shadow.
Summary of the invention
The problem to be solved in the present invention is: the clinoplane shape body side frame structure of available liquid crystal panel backlight causes the optical reflection synergistic effect easily, thereby is easy to generate color spot and shade.
In order to address the above problem, one embodiment of the present of invention have provided a kind of liquid crystal panel backlight, comprise body side frame, bottom framework, be arranged at array of source on the bottom framework, be arranged at the optical mode material at top and be laid in body side frame and the anti-plate in the end of the inner surface of bottom framework, it is characterized in that: the angle of the inner surface of described body side frame and the inner surface of described bottom framework is an acute angle; The outer of the inner surface of described body side frame is shaped as broken line or camber line; The anti-plate in the end that is laid in described body side frame inner surface is corresponding with the shape of this inner surface; The anti-plate in the end that is laid in described bottom framework inner surface is offering opening with the corresponding position of described array of source, makes described array of source expose the anti-plate in the described end.
By the present invention, because body side frame inner surface of the prior art is become non-clinoplane formula structure, and be acute angle with the bottom framework inner surface, therefore can reduce or eliminate because optical reflection synergistic effect and the color spot and the lamp shadow that on the frame all around of liquid crystal panel backlight, produce, thereby can improve display effect.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Embodiment
Embodiment 1
Present embodiment provides a kind of liquid crystal panel backlight, shown in Fig. 2 A, comprise body side frame 1, bottom framework 5, be arranged at array of source 3 on the bottom framework 5, be arranged at the optical mode material 4 at top and be laid in body side frame 1 and the anti-plate 3 in the end of the inner surface of bottom framework 5.
Wherein, the angle of the inner surface of the inner surface of body side frame 1 and bottom framework 5 is an acute angle; The outer of the inner surface of body side frame 1 is shaped as triangle; The anti-plate 3 in the end of inner surface that is laid in body side frame 1 is corresponding with the shape of this inner surface, also is triangle; The anti-plate 3 in the end of inner surface that is laid in bottom framework 5 makes array of source 2 expose the anti-plate 3 in the end offering opening with array of source 2 corresponding positions.Wherein, each light source in the array of source 2 can (be called for short: CCFL) or also can (be called for short: LED) for light emitting diode for cold cathode fluorescent tube.With respect to traditional CCFL, there are not ultraviolet ray and infrared ray in the LED spectrum, radiationless, and discarded object is recyclable, does not pollute, and does not contain mercury element, can safe touch, and have advantages such as power consumption is low, direct drive, the life-span is long, the color rendition scope is big.
Wherein, optical film material 4 can comprise diffuser plate, diffusion barrier, prism film, polaroid etc.The effect of optical film material 4 is in order to make the backlight even light mixing, with purposes such as raising back light source brightness.
In addition, shown in Fig. 2 B, at body side frame 1 and be laid in to run through on the anti-plate 3 in the end on its inner surface and be provided with through hole 6, make the inside and the external communications of liquid crystal panel backlight, to play the effect of heat radiation.And through hole 6 can have a plurality of, is arranged at desired location as the case may be, does not all mark among the figure.
Present embodiment provides another kind of liquid crystal panel backlight, and as shown in Figure 3, with the difference of embodiment 1 be: the outer of the inner surface of body side frame 1 is shaped as serrate.The anti-plate 3 in the end of inner surface that is laid in body side frame 1 is corresponding with the shape of this inner surface, also is serrate.And one or more through holes 6 also can be set in desired location.
