Description

背光模組 Backlight module

本新型關於一種背光模組。 The present invention relates to a backlight module.

目前的背光模組的膠框通常採用不透光的材料，當光線傳遞至背光模組的周緣容易被部分膠框遮擋，使畫面四周的暗影區域面積較大，而導致一較寬的邊框設計。為解決此一問題，如圖1所示，於背光模組100中，一透明三角架102可黏貼於膠框104的側面以承載擴散板106，因此邊緣光線可通過透明三角架102到達顯示面板的邊緣而不被阻擋，獲得減小畫面暗影區域面積的效果。然而，此一設計需額外提供透明三角架而增加構件數，導致製造成本提高、組裝工序繁瑣等問題。 At present, the plastic frame of the backlight module is usually made of an opaque material. When the light is transmitted to the periphery of the backlight module, it is easily blocked by a part of the plastic frame, so that the area of the shadow around the screen is large, resulting in a wider frame design. . To solve this problem, as shown in FIG. 1 , in the backlight module 100 , a transparent tripod 102 can be adhered to the side of the plastic frame 104 to carry the diffusion plate 106 , so that the edge light can reach the display panel through the transparent tripod 102 . The edge is not blocked, and the effect of reducing the area of the shadow area of the picture is obtained. However, this design requires an additional transparent tripod to increase the number of components, resulting in problems such as increased manufacturing costs and cumbersome assembly processes.

Referring to FIG. 2 , the backlight module 10 includes a back plate 12 , at least one light source 14 , a diffusion plate 16 , at least one optical film 18 , and a plastic frame 22 . The backing plate 12 can be configured to form an accommodating space R. For example, the backing plate 12 can include a bottom plate 12a and a side wall 12b. The side wall 12b is connected to the bottom plate 12a and encloses an accommodating space R with the bottom plate 12a. The light source 14 can be disposed in the accommodating space R, and the diffusion plate 16 can be disposed above the accommodating space R. Light source 14 can be, for example, a light emitting diode light strip. Optical diaphragm 18 (for example A brightness enhancement sheet) may be provided on the diffusion plate 16. Light from the light source 14 can pass through the diffuser 16 and the optical film 18, for example, to a display panel (not shown). In this embodiment, the plastic frame 22 is disposed on the backing plate 12 and has a light-transmitting bearing portion 22a. The diffusing plate 16 can bear against the light-transmitting bearing portion 22a of the plastic frame 22 to be disposed above the accommodating space R. The optical film 18 can bear against the light-transmitting bearing portion 22a to be disposed on the diffusion plate 16. In this embodiment, the diffusing plate 16 can bear against a first position P of the transparent carrying portion 22a, and the optical film 18 can bear against a second position Q of the transparent carrying portion 22a, and the second position Q The light source 14 is away from the first position P, but the present invention is not limited thereto. Moreover, in an embodiment, the surface of the light transmissive bearing portion 22a may form a light diffusing microstructure 24 such as a V-shaped groove or an atomized structure to provide, for example, an effect of improving visual taste.

藉由上述實施例的設計，膠框22可同時具有一承載透光件(例如擴散板、光學膜片等)的透光區段(透光承載部22a)及避免光線由背光模組10的側邊露出的一非透光區段22b，故光源14向上發出的光線於抵達擴散板16周緣前，可直接通過可透光的承載部22a而不會被遮擋，獲得減小畫面四周的暗影區域面積的效果，進而使顯示裝置整體可具有較窄的邊框設計。和圖1的習知設計相較，上述實施例將膠框22承載透光件的部分直接由透光材質構成，因此不需使用額外的透明三角架，達到減少構件數、簡化組裝工序並降低製造成本的效果。 With the design of the above embodiment, the plastic frame 22 can simultaneously have a light-transmitting section (light-transmitting bearing portion 22a) carrying a light-transmitting member (for example, a diffusion plate, an optical film, etc.) and avoiding light from the backlight module 10. A non-transparent section 22b is exposed on the side, so that the upwardly emitted light of the light source 14 can pass through the permeable light-transmitting portion 22a without being blocked before reaching the periphery of the diffusion plate 16, thereby obtaining a shadow that reduces the circumference of the screen. The effect of the area of the area, in turn, allows the display device as a whole to have a narrow bezel design. Compared with the conventional design of FIG. 1 , in the above embodiment, the portion of the plastic frame 22 carrying the light transmissive member is directly composed of a light-transmitting material, so that an additional transparent tripod is not required, thereby reducing the number of components, simplifying the assembly process, and reducing The effect of manufacturing costs.

再者，如圖2所示，透光承載部22a可具有實質平行擴散板16的一承載面S，使擴散板16承靠於膠框22時的穩定性更佳，膠框22的透光區段(透光承載部22a)可較遠離光源14且非透光區段22b可較靠近光源14，非透光區段22b可具有一鉛直壁面，且透光承載部22a形成為朝遠離光源方向彎折的彎折部，但本新型並不限定於此，透光承載部22a的外型可視需求加以變化。於另一實施例中，例如圖3所示，膠框22的透光承載部22a可由鉛直的非透光區段22b水平延伸出的延伸部所構成，且擴散板16可承靠於透光承載部22a，同樣可獲得減小畫面四周的暗影區域面積的效果。 Moreover, as shown in FIG. 2, the light-transmitting bearing portion 22a may have a bearing surface S of the substantially parallel diffusing plate 16, so that the stability of the diffusing plate 16 against the plastic frame 22 is better, and the transparent frame 22 is transparent. The section (light-transmitting bearing portion 22a) may be farther away from the light source 14 and the non-light-transmitting section 22b may be closer to the light source 14, the non-light-transmitting section 22b may have a vertical wall surface, and the light-transmitting bearing portion 22a is formed to face away from the light source The bent portion is bent in the direction, but the present invention is not limited thereto, and the appearance of the light-transmitting bearing portion 22a may be changed as needed. In another embodiment, as shown in FIG. 3, the light-transmitting bearing portion 22a of the plastic frame 22 can be formed by an extending portion extending horizontally from the vertical non-transmissive portion 22b, and the diffusing plate 16 can bear the light. The carrying portion 22a can also obtain the effect of reducing the area of the shadow area around the screen.

再者，透光區段(透光承載部22a)的位置及佔整個膠框22的比例並不限定，而可視各種因素例如畫面暗影嚴重程度、側面漏光可能性、元件於容置空間中的配置方式等加以變化而不限定。於一實施例中，非透光區段22b可由白色、灰色或黑色塑膠的不透光或低透光塑膠所構成，以避免光線由膠框22的側邊露出，且透光區段(透光承載部22a)可由透明塑膠所構成。 Furthermore, the position of the light transmitting section (light transmitting bearing portion 22a) and the entire plastic frame 22 The ratio is not limited, and may vary depending on various factors such as the severity of the shadow of the screen, the possibility of side light leakage, the arrangement of the components in the accommodating space, and the like. In an embodiment, the non-transparent section 22b may be made of opaque or low-transmission plastic of white, gray or black plastic to prevent light from being exposed from the side of the frame 22, and the light-transmissive section is transparent. The light carrying portion 22a) may be composed of a transparent plastic.

圖4為本新型另一實施例的背光模組的示意圖。如圖4所示，背光模組30的膠框32限位於背板12且具有一傾斜部32a，擴散板36承靠於膠框32的傾斜部32a上，擴散板36具有一實質平行傾斜部32a的一傾斜端面36a，且於擴散板36承靠於膠框32時，傾斜端面36a可貼附於傾斜部32a。再者，一雙面膠38可另設於傾斜端面36a與傾斜部32a之間且黏結傾斜端面36a與傾斜部32a。 4 is a schematic diagram of a backlight module according to another embodiment of the present invention. As shown in FIG. 4, the plastic frame 32 of the backlight module 30 is limited to the back plate 12 and has an inclined portion 32a. The diffusion plate 36 bears against the inclined portion 32a of the plastic frame 32. The diffusion plate 36 has a substantially parallel inclined portion. An inclined end surface 36a of the 32a, and when the diffusion plate 36 bears against the plastic frame 32, the inclined end surface 36a can be attached to the inclined portion 32a. Further, a double-sided tape 38 may be additionally provided between the inclined end surface 36a and the inclined portion 32a and the inclined end surface 36a and the inclined portion 32a are bonded.

藉由上述實施例的設計，因擴散板36的傾斜端面36a可與膠框傾斜部32a具有實質相同的斜率，使擴散板36承靠於膠框32時其側邊可平貼於膠框32，因此可減少或避免不透光的膠框32遮擋到欲進入擴散板36的光線的可能性，如此同樣可獲得減小畫面四周的暗影區域面積的效果。 With the design of the above embodiment, the inclined end surface 36a of the diffusion plate 36 can have substantially the same slope as the plastic frame inclined portion 32a, so that the side of the diffusion plate 36 can be flat against the plastic frame 32 when the diffusion plate 36 is supported by the plastic frame 32. Therefore, the possibility that the opaque plastic frame 32 blocks the light to enter the diffusion plate 36 can be reduced or avoided, and thus the effect of reducing the area of the shadow area around the picture can be obtained.
