Description
本發明係有關於一種背光模組顯示技術,特別是一種能改變分光角度的光源組件。The present invention relates to a backlight module display technology, particularly a light source assembly capable of changing the light splitting angle.
近年來,隨著顯示技術的發展,發光二極體(light emitting diodes,LED)於液晶顯示器(liquid crystal display,LCD)的背光模組(backlight module)上的應用也逐漸受到重視。In recent years, with the development of display technology, the application of light emitting diodes (LED) in the backlight module of a liquid crystal display (LCD) has gradually attracted attention.
目前常見的背光模組的類型包含直下式背光模組及側光式背光模組。常見的直下式背光模組係以發光二極體作為光源,並將其均勻地配置在反射板上,使光源可以透過上方擴散板等其他組件均勻地傳遞到整個顯示器面板上。Currently, common types of backlight modules include direct-lit backlight modules and edge-lit backlight modules. Common direct-lit backlight modules use light-emitting diodes as light sources and evenly arrange them on the reflector plate so that the light source can be evenly transmitted to the entire display panel through the upper diffuser plate and other components.
直下式背光模組相較於側光式背光模組應用在顯示器上,具有較佳的區域調光、透光均勻度、明暗細節佳,以及對比度等優勢,但其缺點為需要較高密度的光源組件(如發光二極體),因此相較於側光式背光模組,直下式背光模組需要較高的成本以及耗電量,其應用的顯示器體積較厚。Compared with the side-light backlight module used in the display, the direct-lit backlight module has the advantages of better area dimming, light transmission uniformity, better light and dark details, and contrast, but its disadvantage is that it requires higher density. Light source components (such as light-emitting diodes), therefore, compared with edge-lit backlight modules, direct-lit backlight modules require higher cost and power consumption, and the display volume used for their applications is thicker.
為了將低成本,可利用透鏡的外型改變發光二極體出光的張角達到均勻混光的效果,進而去拉開發光二極體之間的節距,以減少發光二極體所需的設置數量。In order to reduce the cost, the shape of the lens can be used to change the angle of light emitted by the light-emitting diode to achieve a uniform light mixing effect, and then to develop the pitch between the light-emitting diodes to reduce the setting required for the light-emitting diode Quantity.
但當發光二極體的數量過少時,會因為背光源分割不夠細緻,導致調光畫面的邊緣會有光暈現象(Halo effect),而背光模組的角落邊緣也會因為光源無法有效傳遞,造成暗角暗邊的現象。However, when the number of light-emitting diodes is too small, the backlight division is not detailed enough, resulting in a halo effect at the edge of the dimming screen, and the corner edge of the backlight module will not be effectively transmitted due to the light source. Causes the phenomenon of dark corners and dark edges.
在一實施例中,一種應用於直下式背光模組的光源組件,包含發光二極體以及透鏡。此透鏡係設置於該發光二極體上方。此透鏡包括本體及複數腳柱。本體具有上表面及下表面,其中,上表面為曲面,且下表面中央處向上凹設有凹槽。此凹槽係對應位於發光二極體位置的上方。複數腳柱設置於本體之下表面,這些腳柱使發光二極體之發光面與本體之下表面於垂直發光面的方向產生間距。In one embodiment, a light source assembly applied to a direct type backlight module includes a light emitting diode and a lens. The lens is arranged above the light-emitting diode. This lens includes a body and a plurality of legs. The main body has an upper surface and a lower surface, wherein the upper surface is a curved surface, and the center of the lower surface is concave upwardly with a groove. The groove is correspondingly located above the position of the light emitting diode. A plurality of legs are arranged on the lower surface of the main body, and these legs make the light emitting surface of the light emitting diode and the lower surface of the main body have a distance in a direction perpendicular to the light emitting surface.
在一實施例中,一種背光模組包含反射板、複數光源組件以及擴散板。複數光源組件設置於該反射板上。此些光源模組包含發光二極體以及透鏡,其中透鏡設置於發光二極體上方。此透鏡包括本體及複數腳柱。此本體具有上表面及下表面,其中,上表面為曲面,且下表面中央處向上凹設有凹槽。此凹槽係對應位於發光二極體位置的上方。腳柱設置於本體之下表面,這些腳柱使發光二極體之發光面與本體之下表面於垂直發光面的方向產生間距。擴散板設置於此些光源模組上方,其中,位於反射板之中心區的各光源組件的間距不同於與位於反射板之邊緣區的各光源組件的間距。In one embodiment, a backlight module includes a reflective plate, a plurality of light source components, and a diffuser plate. A plurality of light source components are arranged on the reflecting plate. These light source modules include a light emitting diode and a lens, wherein the lens is arranged above the light emitting diode. This lens includes a body and a plurality of legs. The body has an upper surface and a lower surface, wherein the upper surface is a curved surface, and the center of the lower surface is concavely upwardly provided with a groove. The groove is correspondingly located above the position of the light emitting diode. The leg posts are arranged on the lower surface of the main body, and the leg posts make a distance between the light emitting surface of the light emitting diode and the lower surface of the main body in a direction perpendicular to the light emitting surface. The diffusion plate is arranged above the light source modules, wherein the distance between the light source components in the central area of the reflector is different from the distance between the light source components in the edge area of the reflector.
有鑑於此,本發明提供一種光源組件和一種背光模組,依據發光二極體之發光面與透鏡本體的下表面垂直於發光面的方向產生的間距的不同能夠使發光二極體之光源射入透鏡凹槽後,折射出的出光角度有所差異,進而去降低減少光源組件數量後造成的光暈現象和背光模組的暗角暗邊問題。In view of this, the present invention provides a light source assembly and a backlight module. According to the difference in the distance between the light emitting surface of the light emitting diode and the lower surface of the lens body perpendicular to the light emitting surface, the light source of the light emitting diode can emit light. After entering the lens groove, the angle of the refracted light is different, thereby reducing the halo phenomenon and the dark corners and dark edges of the backlight module caused by reducing the number of light source components.
請參閱圖1以及圖2,在本實施例中,光源組件100包括透鏡110以及發光二極體150。透鏡110包括本體120和複數個腳柱130。本體120具有上表面121及下表面122。在本實施例中,本體120之上表面121為曲面,以使得發光二極體150射入透鏡110的光線,可以在穿過本體120後由上表面121射出時,可以因折射效果而得到較大的出光角度。但上表面121的曲面形式不特別限制,可如本實施例中所示的曲面,亦或是中心內凹的曲面等,因應光路需求而做改變。且如圖1所示,本體120的下表面122中央處向上凹設有凹槽140。當透鏡110對應組設於發光二極體150上方時,凹槽140將會對應位於發光二極體150的正上方。Please refer to FIG. 1 and FIG. 2. In this embodiment, the
複數個腳柱130分別耦接於下表面122。在本實施例中,腳柱130的數量雖以二為例示做說明,但並不以此為限。腳柱130至少為二個是為了保持透鏡110左右平衡,其數量可為2、3、4或5以上,以達平衡之目的。腳柱130將使得發光二極體150的發光面160與下表面122間於垂直發光面160的方向上產生間距H。The plurality of
在本實施例中,當腳柱130的高度較發光二極體150的高度來得高,則此時間距H即為正值。但在一些實施態樣中,間距H也可以小於零,即間距H為負值。當間距H小於零時,即表示腳柱130的高度較發光二極體150的高度來得矮,此時發光二極體150將會部份容設於凹槽140中。In this embodiment, when the height of the
藉此,可以利用例如調整光源組件100中的腳柱130的長度來改變光源組件100中透鏡110和發光二極體150之間的間距H大小,進而去影響發光二極體150光源透過透鏡110折射出的出光角度。因此,舉例來說,當為了可以降低光暈現象和角落邊緣的暗角暗邊問題,而要使用較大出光角度的光源組件100時,即可藉由調整腳柱130的高度來達成,而不需要製作或開發具有不同折射率的透鏡110。如此,也可以簡化製造工序或開發時程。In this way, for example, the length of the
再請參閱圖1,在本實施例中,透鏡110的腳柱高度為L,而發光二極體150的底面至發光面160的高度為P,則腳柱高度L、高度P以及間距H之間,需符合L=H+P,且 L > 0。並且,為了使得發光二極體150所發出的光能夠全部有效入射至凹槽140中,以經過透鏡110折射出去,因此,當發光面160為圓形且半徑為r,位於本體120下表面122處的凹槽140開口為圓形且半徑為R時,需滿足下列公式:
H < (R-r)/ tan 30° …(1)。1 again, in this embodiment, the height of the leg of the
由於發光二極體150的發光面160所發出之光源會射入凹槽140,且經透鏡110之本體120折射後由透鏡110之上表面121射出。因此,一旦間距H過大,則在發光面160左右二側所發出的光線將不會直接射入至凹槽140中,而是會射入到本體120的下表面122而造成部份反射。也就是說,上述腳柱130高度L將因間距H而有一定的限制,即 L < P +(R-r)/ tan 30°。當腳柱過高時,發光二極體150之光源發射路徑超出凹槽140半徑R,會造成光源從透鏡110下側漏光影響光源表現。如此,將造成發光二極體150所發出之光線的浪費。所以,間距H的高度若能滿足上述式(1)的限制為佳。當間距H較大時,光源從本體120射出的出光角度大於當間距H較小時的出光角度。The light source emitted from the light-emitting
請參閱圖3,圖3所示為使用本實施例上述之背光模組200的光源組件100的使用狀態示意圖。背光模組200包括複數個光源組件100、反射板210以及擴散板220。本實施例之光源組件100可以是直接排列設置於反射板210上,或是將複數個光源組件100先組成複數條光條的方式,再將光條一一排列設置於反射板210上。另外,反射板210亦並非一定要為板狀,也可以是在電路板上再鍍上白漆而形成具反射效果的反射層,進而形成反射板210。另外,圖3中為清楚說明,係簡化長度而直接示意中央區C的單一光源組件100與左右邊緣區E的單一光源組件100。Please refer to FIG. 3. FIG. 3 is a schematic diagram of the use state of the
光源組件100設置於反射板210上。擴散板220在光源組件100以及反射板210上方。發光二極體150將直接耦接於反射板210,而透鏡110的腳柱130則直接設置於反射板210上。整個反射板210上可以分為靠近中央部位的中央區C(Central area)以及靠近側邊或邊角的邊緣區E(Edge area)。而在本實施例中,位於中央區C的光源組件100,其間距H會不同於位於邊緣區E的光源組件100的間距H。The
為使得畫面的中央區C所呈現的影像更為清晰,在中央區C需要以較小的出光角度的光源折射至擴散板220,此時,需要將間距H調整為較小的值,以使得出光角度可以較小。除了前述可以透過直接改變腳柱130的高度L外,也可以如圖3所示,在反射板210上具有複數孔洞211,此些孔洞211的數量可以是對應上述腳柱130的數量,或是僅於需要的位置設置所需數量的孔洞211。而光源組件100的透鏡110的腳柱130則是設置於反射板210表面(如圖3設置於邊緣區E的光源組件100)或分別穿射於孔洞211中(如圖3設置於中央區C的光源組件100)。In order to make the image presented in the central area C of the screen clearer, the light source with a smaller light exit angle in the central area C needs to be refracted to the
藉由將位於中央區C的透鏡110的腳柱130穿設於孔洞211中,即可以使得本體120的下表面122更靠近發光面160,即縮小間距H。也就是說,當需要改變間距H時,只需要改變孔洞211的深度即可。如此,將可以使用統一規格的光源組件100組設於整個背光模組200的任意位置,而不需要依據光源組件100的設置位置而製作各種具有不同腳柱高度L的透鏡110,以減少元件製造的數量。By inserting the
另外,由於在邊緣區E需要以較大的出光角度折射至擴散板220,以將光源較有效地傳達給背光模組200角落,進而減少暗角暗邊的現象。因此,相較於中央區C,位於邊緣區E的光源組件100的透鏡110和發光二極體150之間的間距H需為較大值,進而放大光源的出光角度。在本實施例中,即是利用在反射板210的邊緣區E不設置孔洞211,而是直接以具有腳柱130設置於邊緣區E處的反射板210表面上,以使得間距H較位於中央區C的間距H來得大。In addition, since the edge area E needs to be refracted to the
另外,為了可以為滿足前述的式(1),也可以將腳柱130直接組設於反射板210上時符合上述式(1)的腳柱高度L作為預設的腳柱高度L。隨後再依據所需於反射板210上設置相同或不同深度的孔洞211,以滿足在中央區C或邊緣區E所需要的光源組件100設置模式。In addition, in order to satisfy the aforementioned formula (1), the height L of the foot post conforming to the aforementioned formula (1) when the
再者,在本實施例中,上述孔洞211除了可以用以調整間距H外,也可以幫助光源組件100定位,提高擺放位置的精準度,避免偏心問題。Furthermore, in this embodiment, in addition to adjusting the spacing H, the above-mentioned
為了降低光暈現象和角落邊緣的暗角暗邊問題,除了如上述調整腳柱130的高度或改變孔洞211的深度以調整上述間距H(請參閱圖1)的大小之外,在另一實施例中,腳柱130的形狀為階梯狀,此階梯狀腳柱130A可以包含複數個階梯。In order to reduce the halo phenomenon and the problem of vignetting and dark edges on the corner edges, in addition to adjusting the height of the
請參閱圖4,圖4所示為本發明另一實施例的腳柱立體圖。本實施例與前一實施例相同之結構及元件將不再重複贅述。不同之處在於腳柱之形狀。為清楚說明,圖4為階梯狀腳柱130A的示意圖,以最小數量二階梯呈現,但並不以此為限,亦可依需求使用三階、四階或更多。階梯狀腳柱130A包含第一階梯131、第二階梯132由上而下依序設置,其中第一階梯131寬度大於第二階梯寬度132。Please refer to FIG. 4, which is a perspective view of a foot post according to another embodiment of the present invention. The structure and elements of this embodiment that are the same as those of the previous embodiment will not be repeated. The difference lies in the shape of the feet. For clear description, FIG. 4 is a schematic diagram of the stepped
在另一實施例中,上述階梯狀腳柱130A除了可以設置在反射板210上,亦可對應反射板210之孔洞211,此些孔洞211可依據所需,將孔徑寬度設置為大於第二階梯132的寬度並小於第一階梯131的寬度,且孔徑的深度也可以依照階梯狀腳柱130A的對應的階梯高度設置,使階梯狀腳柱130A的不同階梯穿設在不同的孔徑的孔洞211中。In another embodiment, in addition to being provided on the
如此,透過上述階梯狀腳柱130A的各個階梯的寬度以及高度的設定,可以達到與前述腳柱130同樣的效果,且相較於柱狀腳柱(如圖2所示,但腳柱130不受限於圓柱狀),階梯狀腳柱130A有更廣泛的應用與優勢。例如,當使用具有更多階梯的腳柱時,可依所要設置的腳柱,調整對應的孔洞211的孔徑,當腳柱放入後,即會被擋止於所需要的階梯處,而不需要顧慮到孔洞211的深度是否過深,或因公差可能造成深度不一的問題。或者,當面對具有相同孔徑寬度的孔洞211,階梯狀腳柱130A具有利用不同階梯寬度調整光源組件100的高度。In this way, through the setting of the width and height of each step of the stepped
請參閱圖5,圖5為另一實施例之背光模組200的光源組件100的放置示意圖,其中光源組件100具有另一實施例所述之腳柱130A。背光模組200包括複數個光源組件100、反射板210以及擴散板220。其中光源組件100設置於反射板210上,而擴散板220在光源組件100以及反射板210上方。光源組件100可以如前述是直接排列設置於反射板210上,或是將複數個光源組件100先組成複數條光條,再將光條排列於反射板210上。反射板210、擴散板220以及光源組件100除腳柱為階梯狀腳柱130A外,皆具有前述特徵。另外,圖5中為清楚說明,亦係簡化長度而直接示意右邊為中央區C的二光源組件100與左邊為邊緣區E的二光源組件100間的節距(D1與D2)。Please refer to FIG. 5. FIG. 5 is a schematic diagram of the placement of the
在另一實施例中,位於中央區C的光源組件100藉由將階梯狀腳柱130A的第二階梯132穿設在反射板210上改變腳柱的高度以降低前述間距H,並射出較小出光角度的光源以集中光源至中央區C。而邊緣區E藉由不設置孔洞211使光源組件100具有較高的間距H,並射出較大出光角度的光源至邊緣以減少暗角暗邊的現象。In another embodiment, the
再參閱圖5,中央區C的光源組件100以較小的出光角度的光源折射至擴散板220上,因出光角度較小需要較多數量的光源組件100以達到均勻混光的效果,所以光源組件100間分布較密集,其中光源組件100彼此的節距為D2。而邊緣區E的光源組件100具有出光角度較大,所需的數量較少即可達到均勻混光的效果,因此光源組件100分布較稀疏,其中光源組件100彼此的節距為D1。當中央區C的光源組件100的分布密度大於邊緣區E的分布密度時,D2 < D1。Referring to FIG. 5 again, the
因此,不須製作具有不同高度的孔洞211的背光模組200,在製作時僅需要考量統一規格的光源組件100的不同階梯寬度的階梯狀腳柱130A,改變鑽孔孔徑,即可針對不同需求的背光模組200設置具有不同間距H的光源組件100,並降低製作成本。此外,另一實施例亦可如上述實施例一樣,利用鑽孔幫助光源組件100定位,提高擺放位置的精準度,避免偏心問題,同時降低鑽孔對於反射板210的影響。Therefore, it is not necessary to fabricate the
綜上所述,根據本發明實施例之所提供的光源組件100及背光模組200,可以利用光源組件100中的腳柱130的長度、形狀搭配背光模組200的反射板210上的孔洞211影響光源組件100中透鏡110和發光二極體150之間的間距H大小,進而影響發光二極體150光源透過透鏡110折射出的出光角度。也就是說,可根據背光模組不同位置的需求去調整透鏡的高低,進而去改變出光角度。因此,當邊緣區E使用較大出光角度的光源組件100時,可以降低光暈現象和角落邊緣的暗角暗邊問題。In summary, according to the
