Description
本發明係關於一種顯示裝置及其背光模組，特別關於一種液晶顯示裝置及其側光式背光模組。The present invention relates to a display device and a backlight module thereof, and more particularly to a liquid crystal display device and an edge-lit backlight module thereof.
近年來由於顯示技術的發展，傳統的陰極射線顯像管顯示裝置已逐漸被液晶顯示裝置所取代。其中，由於液晶無法自發光的特性，於液晶顯示裝置中必須利用背光模組作為其背光源。In recent years, due to the development of display technology, conventional cathode ray tube display devices have been gradually replaced by liquid crystal display devices. Among them, due to the inability of the liquid crystal to self-illuminate, a backlight module must be used as a backlight in a liquid crystal display device.
請參照圖1所示，其係為一種習知之液晶顯示裝置1的部分剖面圖。液晶顯示裝置1包含一液晶顯示面板11、一側光式背光模組12以及一外框13。側光式背光模組12具有一框架121、一背板122、一冷陰極螢光燈管123、一導光板124、一燈罩125及一光學膜片組126。Referring to FIG. 1, it is a partial cross-sectional view of a conventional liquid crystal display device 1. The liquid crystal display device 1 includes a liquid crystal display panel 11 , a side light type backlight module 12 , and an outer frame 13 . The edge-lit backlight module 12 has a frame 121, a back plate 122, a cold cathode fluorescent lamp 123, a light guide plate 124, a lamp cover 125, and an optical film set 126.
框架121用來支撐承載液晶顯示面板11，並可固定導光板124及光學膜片組126的位置。再者，框架121可使液晶顯示面板11與側光式背光模組12間具有一距離G，以使由導光板124射出的光線能具有足夠的混光距離，而均勻地入射至液晶顯示面板11。The frame 121 is used to support the liquid crystal display panel 11 and to fix the position of the light guide plate 124 and the optical film group 126. Furthermore, the frame 121 can have a distance G between the liquid crystal display panel 11 and the edge-lit backlight module 12, so that the light emitted by the light guide plate 124 can have a sufficient light-mixing distance and be uniformly incident on the liquid crystal display panel. 11.
冷陰極螢光燈管123設置於燈罩125內，而冷陰極螢光燈管123及燈罩125則設置於導光板124的一側，導光板124則設置於背板122上。藉由燈罩125的反射面可將冷陰極螢光燈管123所發出的光反射進入導光板124，而光學膜片組126則設置於導光板124的出光面並藉由框架121固定，用來使側光式背光模組12的出光擴散均勻。The cold cathode fluorescent lamp tube 123 is disposed in the lamp cover 125, and the cold cathode fluorescent lamp tube 123 and the lamp cover 125 are disposed on one side of the light guide plate 124, and the light guide plate 124 is disposed on the back plate 122. The light emitted from the cold cathode fluorescent lamp 123 can be reflected into the light guide plate 124 by the reflecting surface of the lamp cover 125, and the optical film group 126 is disposed on the light emitting surface of the light guide plate 124 and fixed by the frame 121. The light emitted by the edge-lit backlight module 12 is uniformly diffused.
外框13係設置於液晶顯示面板11之上，以固定液晶顯示面板11與側光式背光模組12，例如外框13係與背板122鎖合固定。另外，外框13尚有保護液晶顯示面板11玻璃的功能。The outer frame 13 is disposed on the liquid crystal display panel 11 to fix the liquid crystal display panel 11 and the edge-lit backlight module 12, for example, the outer frame 13 and the back plate 122 are locked and fixed. In addition, the outer frame 13 has a function of protecting the glass of the liquid crystal display panel 11.
於側光式背光模組12中，燈罩125多利用金屬材質黏附反射材料，再藉由沖壓成型方式製成。然而，藉由沖壓成型的燈罩125由於模具尺寸的限制，僅能對應單一尺寸的側光式背光模組12來製作，對應不同尺寸的側光式背光模組12，則必須利用不同尺寸的模具來製作。且，沖壓成型的製程較為繁複(例如下料、折彎等製程)，而製作過程中的不良品回收再製，製程亦較為繁複(例如金屬熔解、澆鑄再製等製程)，這些都會造成側光式背光模組12的製程效率的降低及製作成本的提高。In the edge-lit backlight module 12, the lampshade 125 is made of a metal material and a reflective material, and is formed by stamping. However, the stamped and formed lampshade 125 can only be fabricated corresponding to a single-sized edge-lit backlight module 12 due to the limitation of the size of the mold. For the different-sized edge-lit backlight modules 12, different sizes of molds must be utilized. To make. Moreover, the process of stamping and forming is complicated (for example, cutting, bending, etc.), and the defective products are recycled and processed in the manufacturing process, and the process is complicated (for example, metal melting, casting and other processes), which will result in side-lighting. The process efficiency of the backlight module 12 is reduced and the manufacturing cost is improved.
另外，側光式背光模組12中的框架121多利用塑膠材質射出成型而製成，故需要再購置另一模具，而造成生產成本增加。再者，外框13與背板122必須利用工具(例如螺絲起子)來進行鎖合固定，如此不僅易造成液晶顯示裝置1的組裝效率差，且於組裝過程中也易產生人為的誤差，進而造成產品的良率降低。In addition, the frame 121 in the edge-lit backlight module 12 is mostly formed by injection molding of a plastic material, so that another mold needs to be purchased, resulting in an increase in production cost. Moreover, the outer frame 13 and the back plate 122 must be locked and fixed by using a tool (for example, a screwdriver), which not only causes the assembly efficiency of the liquid crystal display device 1 to be poor, but also causes human error in the assembly process, and further Result in reduced product yield.
因此，如何提供一種能降低成本及提高製作組裝效率的液晶顯示裝置及其側光式背光模組，已逐漸成為重要課題之一。Therefore, how to provide a liquid crystal display device and an edge-light type backlight module capable of reducing cost and improving assembly efficiency have gradually become one of important topics.

請參照圖2所示，其為本發明第一實施例之液晶顯示裝置2的部分剖面圖。液晶顯示裝置2例如可應用於液晶顯示器或者液晶電視，液晶顯示裝置2包含一液晶顯示面板3及一側光式背光模組4。Referring to FIG. 2, a partial cross-sectional view of a liquid crystal display device 2 according to a first embodiment of the present invention is shown. The liquid crystal display device 2 can be applied to, for example, a liquid crystal display or a liquid crystal television. The liquid crystal display device 2 includes a liquid crystal display panel 3 and a side optical backlight module 4.
液晶顯示面板3係包含一薄膜電晶體基板、一彩色濾光片基板及一液晶層等結構。於圖2中為能清楚表示液晶顯示裝置2整體結構，液晶顯示面板3的結構係省略表示，然而實際應用時，液晶顯示面板3應具有該等結構。The liquid crystal display panel 3 includes a thin film transistor substrate, a color filter substrate, and a liquid crystal layer. In FIG. 2, the overall structure of the liquid crystal display device 2 can be clearly shown, and the structure of the liquid crystal display panel 3 is omitted, but in actual use, the liquid crystal display panel 3 should have such a structure.
側光式背光模組4與液晶顯示面板3連接，具有一導光板41、至少一發光元件42及至少一擠型元件43。於此，側光式背光模組4係以一應用於液晶顯示裝置內之背光模組為例，當然，側光式背光模組4也可為一燈箱或一指示器(indicator)。The edge-lit backlight module 4 is connected to the liquid crystal display panel 3 and has a light guide plate 41, at least one light-emitting element 42 and at least one extruded element 43. For example, the edge-lit backlight module 4 is an example of a backlight module applied to a liquid crystal display device. Of course, the edge-lit backlight module 4 can also be a light box or an indicator.
導光板41之材質可為高分子聚合物(例如聚碳酸酯)並於其底面具有光學結構，以將發光元件42所發出的光線由水平方向轉為垂直方向並射至液晶顯示面板3。The material of the light guide plate 41 may be a high molecular polymer (for example, polycarbonate) and has an optical structure on the bottom surface thereof to convert the light emitted from the light emitting element 42 from the horizontal direction to the vertical direction and to the liquid crystal display panel 3.
發光元件42例如為一冷陰極螢光燈管(Cold Cathode Fluorescent Lamp,CCFL)或一發光二極體(Light Emitting Diode,LED)，於此，發光元件42係為一冷陰極螢光燈管，並設置於導光板41的一側邊。The light-emitting element 42 is, for example, a Cold Cathode Fluorescent Lamp (CCFL) or a Light Emitting Diode (LED). Here, the light-emitting element 42 is a cold cathode fluorescent lamp. And disposed on one side of the light guide plate 41.
擠型元件43例如可為金屬材質(例如鋁)、或熱塑性塑膠材質、或熱固性塑膠材質或複合性塑膠材質等，並具有一容置部431及一承載部432，而擠型元件43係設置於導光板41的至少一側邊，當然，也可以設置於導光板41的相鄰二側、相對二側或者是四邊均設置擠型元件43。發光元件42設置於容置部431內，承載部432的高度則定義出導光板41與液晶顯示面板3之間的距離G1，並支撐承載液晶顯示面板3。The extruded component 43 can be, for example, a metal material (for example, aluminum), or a thermoplastic plastic material, or a thermosetting plastic material or a composite plastic material, and has a receiving portion 431 and a carrying portion 432, and the extruded member 43 is provided. On at least one side of the light guide plate 41, of course, the extruded element 43 may be disposed on the adjacent two sides, the opposite sides, or the four sides of the light guide plate 41. The light-emitting element 42 is disposed in the accommodating portion 431. The height of the carrying portion 432 defines a distance G1 between the light guide plate 41 and the liquid crystal display panel 3, and supports the liquid crystal display panel 3.
再者，擠型元件43可利用擠型製程而為一體成型。而依實際產品需求可設計不同形狀的擠型模具，以改變承載部432的高度，如此一來，由導光板41射出的光線能具有足夠的混光距離，而均勻地入射至液晶顯示面板3。若擠型元件43為熱塑性塑膠材質、或熱固性塑膠材質或複合性塑膠材質，則容置部431例如可具有一反射層或一反射膜片，而反射層或反射膜片可為白色、銀色或金色等色系的不透明材料(例如可為塑膠材料)，並以貼附、噴塗、沉浸、表面鍍膜等方式形成。再者，擠型元件43為塑膠材質亦可直接使用高反射率之高分子材料進行擠製成型，如此也可直接賦予擠型元件43之容置部431反射光線之機能。Further, the extruded member 43 can be integrally formed by an extrusion process. According to the actual product requirements, different shapes of the extrusion die can be designed to change the height of the bearing portion 432. Thus, the light emitted by the light guide plate 41 can have a sufficient light mixing distance and uniformly incident on the liquid crystal display panel 3. . The accommodating portion 431 may have a reflective layer or a reflective film, for example, the reflective layer or the reflective film may be white, silver, or a thermoplastic material, or a thermosetting plastic material or a composite plastic material. Gold-colored opaque materials (for example, plastic materials) are formed by attaching, spraying, immersing, surface coating, and the like. Furthermore, the extruded component 43 is made of a plastic material and can be directly extruded using a high-reflectivity polymer material, so that the function of reflecting light by the receiving portion 431 of the extruded component 43 can be directly applied.
值得一提的是，若擠型元件43為金屬材質，容置部431亦可具有反射層或反射膜片。因此，發光元件42所發出的光線，可藉由擠型元件43之容置部431的反射層或反射膜片反射進入導光板41，以提升光線利用率。It is worth mentioning that if the extruded element 43 is made of a metal material, the receiving portion 431 may also have a reflective layer or a reflective film. Therefore, the light emitted by the light-emitting element 42 can be reflected into the light guide plate 41 by the reflective layer or the reflective film of the receiving portion 431 of the extruded element 43 to improve the light utilization efficiency.
另外，於本實施例中，側光式背光模組4更可包含一光學膜片組44及一反射膜片45。光學膜片組44例如可具有擴散膜片或增亮膜片等，並設置於擠型元件43之承載部432與導光板41之間。反射膜片45相對於光學膜片組44設置於導光板41的底面，用以將光線向上反射至液晶顯示面板3，以提高側光式背光模組4光線利用率。In addition, in the embodiment, the edge-lit backlight module 4 further includes an optical film set 44 and a reflective film 45. The optical film group 44 may have, for example, a diffusion film or a brightness enhancement film or the like, and is disposed between the carrier portion 432 of the extruded member 43 and the light guide plate 41. The reflective film 45 is disposed on the bottom surface of the light guide plate 41 relative to the optical film set 44 for reflecting the light upward to the liquid crystal display panel 3 to improve the light utilization efficiency of the edge-lit backlight module 4.
因此，對應不同尺寸的側光式背光模組4，可直接擠製成型不同長度的擠型元件43，而擠製成型的製程較沖壓成型的製程為簡易，且製作過程中不良品的擠型元件43可回收再製，因此本實施例之側光式背光模組4可有效地提高製程效率以及降低製作成本。另外，本實施例之擠型元件43可整合如圖1所示之習知液晶顯示裝置1之燈罩125的光反射及框架121的支撐承載功能，藉此，不僅可進行製程整合以提高側光式背光模組4製作效率，且減少組裝元件數量亦可提高液晶顯示裝置2組裝效率。Therefore, the edge-lit backlight modules 4 of different sizes can be directly extruded into the extruded elements 43 of different lengths, and the process of the extrusion molding process is simpler than that of the stamping process, and the defective products are produced during the manufacturing process. The squeezing element 43 can be recycled and reprocessed. Therefore, the edge-lit backlight module 4 of the embodiment can effectively improve the process efficiency and reduce the manufacturing cost. In addition, the extruded element 43 of the present embodiment can integrate the light reflection of the lamp cover 125 of the conventional liquid crystal display device 1 shown in FIG. 1 and the supporting and carrying function of the frame 121, thereby not only performing process integration to improve the side light. The backlight module 4 is efficient in production, and the number of assembled components can be reduced to improve the assembly efficiency of the liquid crystal display device 2.
