Description

直下式背光模块Direct Type Backlight Module

(1)技术领域(1) Technical field

本发明有关一种直下式背光模块，且特别是有关一种具大视角与均匀光源的直下式背光模块。The present invention relates to a direct-type backlight module, and in particular to a direct-type backlight module with a large viewing angle and a uniform light source.

(2)背景技术(2) Background technology

近年来，液晶显示器(Liquid Crystal Display，LCD)因具体积薄、重量轻以及低电磁辐射等优点，逐渐被广泛地使用。而随着科技的日新月异，为了适应瞬息万变的市场需求，液晶显示器的功用及效能一直在创新与增进。其中，广视角的液晶显示器为众多改革发展方向之一，而平面光源的使用，更使得液晶显示器具有色彩多、亮度高、发光面均匀、色彩柔和与容易操控等特点。In recent years, liquid crystal displays (Liquid Crystal Displays, LCDs) are gradually being widely used due to the advantages of thin size, light weight, and low electromagnetic radiation. With the rapid development of science and technology, in order to adapt to the ever-changing market demand, the functions and performance of liquid crystal displays have been innovating and improving. Among them, the liquid crystal display with wide viewing angle is one of many reform and development directions, and the use of flat light source makes the liquid crystal display have the characteristics of multi-color, high brightness, uniform light-emitting surface, soft color and easy control.

一般的液晶显示器主要包括一显示面板及一背光模块，以一具有多个平面光源的直下式背光模块为例，请同时参照图1A与图1B。图1A是传统的直下式背光模块的俯视图，而图1B是图1A的直下式背光模块的剖面图。对于传统配置有平面光源的直下式背光模块(direct backlight module)100而言，直下式背光模块100包括有一灯座110、一光学组件150以及多个光源160。多个光源160是冷阴极平面荧光灯(Cold Cathode Flat Fluorescent Lamp，CCFFL)，用以提供液晶显示器所需的平面光源。灯座110具有一容置槽，而多个光源160是配置于容置槽120中，且每一冷阴极平面荧光灯彼此相邻排列。光学组件150是配置于灯座110上，其中，光学组件150包含有使光线均匀扩散的扩散板(diffuser)以及使光线聚集的集光组件等。集光组件例如是一增光膜(Brightness Enhancement Film，BEF)或一双增光膜(Dual Brightness Enhancement Film，DBEF)。A general liquid crystal display mainly includes a display panel and a backlight module. Taking a direct-lit backlight module with multiple planar light sources as an example, please refer to FIG. 1A and FIG. 1B at the same time. FIG. 1A is a top view of a conventional direct-type backlight module, and FIG. 1B is a cross-sectional view of the direct-type backlight module of FIG. 1A . For a conventional direct backlight module 100 configured with a planar light source, the direct backlight module 100 includes a lamp holder 110 , an optical component 150 and a plurality of light sources 160 . The plurality of light sources 160 are cold cathode flat fluorescent lamps (Cold Cathode Flat Fluorescent Lamp, CCFFL), which are used to provide planar light sources required by the liquid crystal display. The lamp holder 110 has an accommodating groove, and a plurality of light sources 160 are disposed in the accommodating groove 120 , and each cold cathode flat fluorescent lamp is arranged adjacent to each other. The optical component 150 is disposed on the lamp holder 110 , wherein the optical component 150 includes a diffuser for uniformly diffusing light, a light collecting component for concentrating the light, and the like. The light collecting component is, for example, a Brightness Enhancement Film (BEF) or a dual Brightness Enhancement Film (DBEF).

由于冷阴极平面荧光灯的发光原理是利用平面式微碳电极发射出电子，促使气体分子游离成为等离子体(plasma)状态产生紫外线，进而激发荧光粉发出可见光。当光线自光源160发散至光学组件150时，光线皆以一垂直于容置槽120底面的角度发散，如图1B所示。这样位于光学组件150的两端区域140便无法有均匀且充足的的光线入射，故于光学组件150的两端区域140中也无均匀且充足的的光线能被均匀地扩散并导引至显示面板，使得显示面板的光度不均，故对于大视角的显示器而言，边缘亮度的不足影响到显示面板整体画素的亮度及视角表现，造成显像品质不佳。The light-emitting principle of the cold-cathode flat fluorescent lamp is to use the planar micro-carbon electrode to emit electrons, which promotes the dissociation of gas molecules into a plasma (plasma) state to generate ultraviolet rays, and then excites the phosphor to emit visible light. When the light diverges from the light source 160 to the optical component 150 , the light diverges at an angle perpendicular to the bottom surface of the receiving groove 120 , as shown in FIG. 1B . In this way, the two end regions 140 of the optical component 150 cannot have uniform and sufficient light incidence, so there is no uniform and sufficient light in the two end regions 140 of the optical component 150 that can be evenly diffused and guided to the display. Therefore, for a display with a large viewing angle, insufficient edge brightness affects the overall pixel brightness and viewing angle performance of the display panel, resulting in poor image quality.

Two embodiments are given here, which will be described in detail below in conjunction with the accompanying drawings.

第一实施例first embodiment

请参照图2，其是依照本发明第一实施例的直下式背光模块的示意图。直下式背光模块200，可设置于液晶显示器中，且直下式背光模块200至少包括：灯座210、间隔材230a与230b、光学组件250及光源260a与260b。Please refer to FIG. 2 , which is a schematic diagram of a direct-lit backlight module according to a first embodiment of the present invention. The direct-type backlight module 200 can be disposed in a liquid crystal display, and the direct-type backlight module 200 at least includes: a lamp holder 210, spacers 230a and 230b, an optical component 250, and light sources 260a and 260b.

灯座210形成有一容置槽220，且于容置槽220上设置有间隔材230a与230b。间隔材230a与230b较佳地被设置于容置槽220的两侧，用以分别承载光源260a与260b。光学组件250则配置于灯座210上方，并位于光源260a与260b的上方。The lamp holder 210 is formed with an accommodating groove 220 , and spacers 230 a and 230 b are disposed on the accommodating groove 220 . The spacers 230a and 230b are preferably disposed on both sides of the accommodating groove 220 for carrying the light sources 260a and 260b respectively. The optical component 250 is disposed above the lamp holder 210 and above the light sources 260a and 260b.

由于间隔材230a与230b具有一斜面表面，使得当光源260a与260b分别置放于间隔材230a与230b上时，光源260a与260b得以成一固定角度A的方式，配置于灯座210上。光源260a与260b可分别依据间隔材230a与230b的斜面的倾斜角度来作调整，较佳地将光源260a与260b所发射的光线分别投射至光学组件250的两端区域240中。Since the spacers 230a and 230b have an inclined surface, when the light sources 260a and 260b are placed on the spacers 230a and 230b respectively, the light sources 260a and 260b can be disposed on the lamp holder 210 at a fixed angle A. The light sources 260a and 260b can be adjusted according to the inclination angles of the slopes of the spacers 230a and 230b respectively, preferably projecting the light emitted by the light sources 260a and 260b to the two end regions 240 of the optical component 250 respectively.

In this way, a larger viewing angle and a more uniform surface light source can be obtained. Furthermore, by virtue of the diffusion and light collection functions of the optical component 250, the light can be evenly dispersed and guided to the display panel of the liquid crystal display, which can overcome the problem of insufficient edge brightness when the existing large-viewing-view display is used, and further enable the The brightness and viewing angle of the display panel tend to be consistent, and the image quality can be improved. Here, the display panel is, for example, a liquid crystal display panel (Liquid Crystal Display, LCD).

In this way, a larger viewing angle and a more uniform surface light source can be obtained. Furthermore, by virtue of the diffusion and light collection functions of the optical component 350, the light can be evenly dispersed and guided to the display panel of the liquid crystal display, which can overcome the problem of insufficient edge brightness when the existing large-viewing-view display is used, and further enable the The brightness and viewing angle of the display panel tend to be consistent, and the image quality can be improved. Here, the display panel is, for example, a liquid crystal display panel (LCD).
