技术领域 FIELD

[0001] 本发明涉及液晶终端技术,具体的说是涉及一种新型液晶模组导光板及其背光源。 [0001] The present invention relates to a liquid terminal technology, specifically relates to a novel liquid crystal module and the backlight guide plate.

背景技术 Background technique

[0002] 在常规的侧入式液晶模组中,都会使用到导光板,传统的导光板上有规律分布的油墨网点,用于将侧入光导向模组正向出光,光源一股使用发出白光的CCFL (冷阴极灯管) 或者LED (发光二极体)。 [0002] In a conventional side-type liquid crystal module, a light guide plate are used, an ink dot on a regular distribution of a conventional light guide plate, the light incident side for forward light guide module, the light source emits an white CCFL (cold cathode fluorescent lamp), or LED (light emitting diode). 导光板上的油墨网点呈圆形并均勻分布在导光板上,直接将光源发出的白光导向模组。 Ink dots on the light guide plate has a circular shape and uniformly distributed over the light guide plate, the guide white light emitted directly to the module. 而一股可发出白光的光源(如CCFL、LED)内部都涂有荧光粉,也增加了制造工序,导致该种光源市场价格较高,进而增加液晶模组制造成本。 And the light source (e.g., CCFL, LED) emit white light may be an internal coated with phosphor, also increased the manufacturing process, resulting in a higher market price of the seed light source, thereby increasing the manufacturing cost of the LCD module.

发明内容 SUMMARY

[0003] 本发明所要解决的技术问题是:提出一种新型液晶模组导光板及其背光源,简化光源制造工序,降低成本。 [0003] The present invention solves the technical problem: a novel liquid crystal module and the backlight guide plate, a light source to simplify the manufacturing process and reduce costs.

具体实施方式 Detailed ways

[0008] 下面结合实施例对本发明作进一步的描述。 [0008] The following embodiments in conjunction with embodiments of the present invention will be further described.

[0009] 本发明提出了一种新型液晶模组导光板,简化光源制造工序,降低成本,相对于传统技术,本发明的主要改进点在于:在传统的导光板上分布的油墨网点中掺杂荧光粉,荧光粉有红、绿、蓝三基色,厂商可以根据用户对色度的要求进行颜色配比,由于荧光粉具有吸收不可见光转化为可见光的特性,因此搭配的光源可使用非白光光源,例如发出紫外光的冷阴极灯管或发出蓝光的发光二极体。 [0009] The present invention provides a novel liquid crystal module guide plate, a light source to simplify the manufacturing process, reduce costs, compared to conventional techniques, the main points of the present invention is improved: the distribution of ink dots on a conventional light guide plate doped phosphors, fluorescent red, green, and blue color, the manufacturer may be color matching based on user requirements for chromaticity, due to the phosphor has a property of absorbing visible light is not converted to visible light, so the light source may be used with non-white light sources , for example, cold cathode fluorescent lamp emitting ultraviolet light or a light emitting diode emitting blue light. 这样就能简化光源制造工序,降低光源成本。 Such a light source can simplify the manufacturing process, reduce the cost of the light source.

[0010] 实施例: [0010] Example:

[0011] 本例中的新型液晶模组导光板,在导光板上分布着油墨网点,所述油墨网点中掺杂有荧光粉,荧光粉在所有油墨网点中均勻分布,与该导光板搭配的背光源为发出紫外光的冷阴极灯管或发出蓝光的发光二极体。 The [0011] Novel liquid crystal module according to the present embodiment the light guide plate, the light guide plate on the distribution of ink dots, the ink dot is doped with phosphor, the phosphor ink is uniformly distributed across all of the outlets, and with the light guide plate the backlight to emit ultraviolet light of the cold cathode fluorescent lamp or a light emitting diode emits blue light. 荧光粉具有红、绿、蓝三基色,如果需要液晶模组显示红色,则全部采用红色荧光粉;如果需要液晶模组显示绿色,则全部采用绿色荧光粉; 如果需要液晶模组显示蓝色,则全部采用蓝色荧光粉;而如果需要液晶模组显示黄色,则采用部分红色荧光粉与部分绿色荧光粉的组合,黄色的颜色深浅由红色荧光粉与绿色荧光粉之间的比例决定。 Phosphor has a red, green, blue color, red liquid crystal module if necessary, in all the phosphors of red; green liquid crystal module if necessary, is used in all the green phosphor; blue LCD module if necessary, in all the blue phosphor; and if desired LCD module display yellow, the red phosphor in combination with some portion of the green phosphor employed, the yellow color depth is determined by the ratio between the green phosphor and the red phosphor.
