液晶显示器的光源模块 The liquid crystal display of the light source module

技术领域 FIELD

本实用新型涉及一种液晶显示器面板(LCD Panel)的光源模块,特别是指一种使用在液晶显示器面板并以发光二极管(LED)为光源的光源模块(lightmodule)中光源的改良结构,能够借由在光源模块中导光板(LGP)的入光面、出光面或导光棒(LGS)的入光面、出光面涂布混合荧光粉,再经由紫外光发光二极管激发该混合荧光粉后,产生三波长的白光,取代NICHIA的白光LED作为光源,以减少生产成本,并能增加液晶显示器的色彩表现。 The present invention relates to a liquid crystal display panel (LCD Panel) light source module, and particularly to a liquid crystal display panel and used in a light emitting diode (LED) as a light source of the improved structure of the light source module (lightmodule) light source, it is possible by in the light source module by a guide plate (LGP) into the surface, or the surface of the light guide rod (the LGS) of the light incident surface, a mixed phosphor coated surface, and then through the ultraviolet light emitting diode excited phosphor after mixing, three wavelengths to produce white light, substituted NICHIA white LED as a light source, in order to reduce production costs and increase performance color liquid crystal display.

背景技术 Background technique

传统的液晶显示器,由于显示的数字或图案等,不像发光二极管般刺眼,故视觉上显得极高雅。 Conventional liquid crystal display, since the display pattern of numbers or the like, unlike glare as light emitting diodes, it visually seems very elegant. 但是液晶显示器的缺点,是本身不发光,故需提供额外的光源模块,使在外界环境没有光线时仍能显像于屏幕上。 But the disadvantage of the liquid crystal display, does not emit light per se, it is required to provide an additional light source module, so that when there is no ambient light is still on the screen imaging.

在液晶显示器面板的前光源模块100中,以发光二极管(LED)102为光源的导光原理是先由LED102将光线导入导光棒(LGS)104,接着由导光棒104将光线导入导光板(LGP)106,最后再将光线导到液晶显示器面板108的表面,传统的前光源模块结构及光线在结构中进行的路径示意图如图1A及图1B的箭号所示,其中LED光源是采用日亚(Nichia)专利保护的双波长白光LED,如图2所示。 In the liquid crystal display panel before the light source module 100, the light guide principle light emitting diode (LED) 102 as a light source is introduced first by the light LED102 light guide rod (the LGS) 104, followed by a light guide bar 104 introduced into the light guide plate (LGP) 106, and then finally to a surface of the light guide of the liquid crystal display panel 108, as shown by arrows 1A and 1B of the front path conventional light source module for the structure and in the structure diagram shown, wherein the LED light source is dual wavelength patented Nichia (Nichia) white LED, as shown in FIG.

图3显示的是液晶显示器面板的背光源模块300,其以发光二极管(LED)302为光源的导光原理是由LED302将光线导入导光板(LGP)306,经由反射板(reflector sheet)305、扩散板(diffuser sheet)307、棱镜板(prismsheet)309,最后再将光线导到液晶显示器面板308的表面,传统的背光源模块中光线在结构中进行的路径示意图如图3的箭号所示,与前述相同,LED302光源是采用日亚(Nichia)专利保护的双波长白光LED,如图2所示。 Figure 3 shows a liquid crystal display panel, a backlight module 300, the light guide principle light emitting diode (LED) 302 as a light source is introduced into the light guide plate LED302 (LGP) 306, via a reflection plate (reflector sheet) 305, a diffusion plate (diffuser sheet) 307, a prism plate (prismsheet) 309, and then finally to a surface of the light guide of the liquid crystal display panel 308, arrow 3 conventional backlight module structure in the path of the light carried in a schematic view shown in FIG. with the same, LEDs 302 dual wavelength light source is a white LED patent Nichia (Nichia), as shown in FIG.

所谓白光是多种颜色混合而成的光,以人类眼睛所能见的白光形式至少需两种光混合,二波长光(蓝色光+黄色光)或三波长光(蓝色光+绿色光+红色光),目前已商品化的产品有二波长蓝光单芯片加上黄色(YAG)荧光粉,及在未来较被看好的三波长光,其是以紫外光芯片加上红蓝绿(RGB)三颜色荧光粉,除此之外有机单层三波长型白光LED也有成本低、制作容易的优点。 The so-called white light is obtained by mixing a plurality of colors of light to the human eye can see the white form of at least two kinds of light required mixing, two-wavelength light (yellow light + blue light) or a three-wavelength light (blue light + green light + red light), has commercialized products are single-chip two-wavelength blue plus yellow (YAG) phosphor, and a three-wavelength light in the future more promising, which is UV chip plus red, blue and green (RGB) three color phosphors, in addition to the organic monolayer three-wavelength type white LED has a low cost, manufacturing can be easy.

在技术方面,白光LED目前主要分为2种发光方式:目前主要的商品化作法是NICHIA以460nm波长的InGaN蓝光发光管402涂上一层YAG荧光物质404,利用蓝光LED照射此一荧光物质以产生与蓝光互补的555nm波长黄光,在利用透镜原理将互补的黄光、蓝光予以混合,便可得出肉眼所需的白光,如图4所示的白光LED结构图。 In the technology, the white LED is currently divided into two kinds of light emitting ways: main commercial practice NICHIA to 460nm wavelength InGaN blue light emitting tube 402 coated YAG fluorescent material 404, using a blue LED and irradiating the fluorescent substance generating complementary to blue 555nm wavelength yellow light by the lens to be in principle the complementary yellow, blue mixed, white light can be obtained the desired eye, white LED structure of FIG shown in FIG. 第二种是日本住友电工开发出以ZnSe为材料的白光LED。 The second is to develop Sumitomo Electric ZnSe as a material of white LED. 白光LED用在照明或是LCD面板光源模块的光源上,前景备受全球瞩目,欧、美及日本等先进国家也投注许多人力,并成立专门的机构推动白光LED研发工作。 White LED light source used in the LCD panel illumination or light source module, the prospects global attention, Europe, America and Japan and other advanced countries are also betting a lot of manpower, and set up a special agency to promote white LED research and development. 而目前白光LED的关键技术-蓝光技术专利权掌握在日亚Nichia等少数厂商手中,导致精于量产、降低成本的我国业者切入困难,故白光LED目前受制于价格的推广困境,对于制作LCD面板光源模块的业者而言,也将因白光LED的高单价,而致使生产成本无法降低。 The current white LED key technologies - Blu-ray technology patents in the hands of a small number of manufacturers such as Nichia Nichia, leading expertise in mass production, reduce the cost of our industry is difficult to cut, so the white LED currently subject to price promotion dilemma for LCD production panel industry in terms of the light source module, but also due to the high price of the white LED, which results in production cost can not be reduced.
