Abstract
Description
本發明係關於一種顯示器模組，尤其是具有簡化結構以承靠顯示面板之顯示器模組。The present invention relates to a display module, and more particularly to a display module having a simplified structure for bearing a display panel.
就相同螢幕尺寸而言，平面顯示面板使用非常少的電力，體積相對較小，且影像品質非常好，因此已逐漸取代體積龐大的陰極線管顯示器。尤其是在攜帶式電子產品的應用中(例如筆記型電腦)，輕、薄的平面顯示面板已成為不可或缺的重要元件之一。In terms of the same screen size, the flat display panel uses very little power, is relatively small in size, and has excellent image quality, so it has gradually replaced the bulky cathode line display. Especially in the application of portable electronic products (such as notebook computers), light and thin flat display panels have become an indispensable and important component.
然而，平面顯示面板的散熱問題，已進一步成為攜帶式電子產品整合的重要考量因素。舉例而言，圖1及圖2係習知顯示器模組之部份截面示意圖。如圖1所示，習知顯示器模組(如筆記型電腦)係利用軟性印刷電路12板係作為光源14的承載基板，進而利用金屬背框16達成光源的散熱機制。而平面顯示面板18則利用維持背光模組光學膜26容置空間(d)之塑料框19所提供的承靠面20，置於導光板22的上方。然而因軟性印刷電路板12的散熱效果不佳，使得如此配置的裝置具有散熱問題。為改善圖1之散熱問題，圖2之習知技術中，進一步提供導熱膠24於軟性印刷電路板12及金屬背框16之間。然而，因導熱膠24的使用，將使得金屬背框16厚度突出而增加了整合的模組厚度，不利於電子產品縮小化的趨勢。However, the heat dissipation problem of flat display panels has become an important consideration for the integration of portable electronic products. For example, FIG. 1 and FIG. 2 are partial cross-sectional views of a conventional display module. As shown in FIG. 1 , a conventional display module (such as a notebook computer) uses a flexible printed circuit board 12 as a carrier substrate of the light source 14 , and further utilizes a metal back frame 16 to achieve a heat dissipation mechanism of the light source. The flat display panel 18 is placed above the light guide plate 22 by the bearing surface 20 provided by the plastic frame 19 that maintains the space (d) of the backlight module optical film 26 . However, the device thus configured has a heat dissipation problem due to the poor heat dissipation effect of the flexible printed circuit board 12. In order to improve the heat dissipation problem of FIG. 1, in the prior art of FIG. 2, a thermal conductive adhesive 24 is further provided between the flexible printed circuit board 12 and the metal back frame 16. However, due to the use of the thermal conductive adhesive 24, the thickness of the metal back frame 16 will be increased to increase the thickness of the integrated module, which is not conducive to the trend of miniaturization of electronic products.
此外，由於技術不斷的進步，背光模組的光學膜26也隨之簡化，使得顯示面板18及導光板22間的間隙(d)也隨之縮小。然而，因塑料框19的射出成型製程有其極限，使得利用塑料框厚度所界定的光學膜空間無法配合先進光學膜的技術縮減，故必須提供其他的設計以作為顯示面板的承靠。In addition, due to continuous advancement in technology, the optical film 26 of the backlight module is also simplified, so that the gap (d) between the display panel 18 and the light guide plate 22 is also reduced. However, since the injection molding process of the plastic frame 19 has its limit, the optical film space defined by the thickness of the plastic frame cannot be reduced with the technology of the advanced optical film, so other designs must be provided as the bearing of the display panel.
因此，有必要提供一種可有效提供散熱機制又具有簡化結構之顯示器模組。Therefore, it is necessary to provide a display module which can effectively provide a heat dissipation mechanism and has a simplified structure.
鑑於上述先前技術的不足，本發明一方面在於提供一種顯示器模組，其利用承載光源之基板同時用以承靠顯示面板，以簡化整體結構減少製造成本。In view of the above-mentioned deficiencies of the prior art, an aspect of the present invention is to provide a display module that utilizes a substrate carrying a light source to simultaneously bear against a display panel to simplify the overall structure and reduce manufacturing costs.
本發明又一方面在於提供一種顯示器模組，其整合光源之散熱基板與金屬框之配置，以有效增進散熱效果並增加承靠顯示面板之功效。Another aspect of the present invention provides a display module that integrates the arrangement of a heat dissipation substrate and a metal frame of a light source to effectively enhance the heat dissipation effect and increase the efficiency of bearing the display panel.
於一實施例，本發明提供一種顯示器模組，其包含一導光板；一光源配置於導光板之一端；以及一基板供設置光源，且基板部分延伸於導光板上方以供承靠一顯示面板。In one embodiment, the present invention provides a display module including a light guide plate, a light source disposed at one end of the light guide plate, and a substrate for providing a light source, and the substrate portion extending over the light guide plate for receiving a display panel .
本發明之顯示器模組更包含一金屬框，供容設導光板、光源、及基板。於一實施例，金屬框包含一主體及一反折上緣自 主體直立延伸反折，其中主體係供容設導光板，且反折上緣係部份包覆基板。於一例示實施例，基板包含一金屬材質，以作為光源之散熱基板。The display module of the present invention further comprises a metal frame for accommodating the light guide plate, the light source, and the substrate. In one embodiment, the metal frame includes a body and a reverse upper edge The main body extends vertically and reflexes, wherein the main system is provided with a light guide plate, and the upper edge of the reverse fold partially covers the substrate. In an exemplary embodiment, the substrate comprises a metal material to serve as a heat sink substrate for the light source.
於另一實施例，顯示器模組更包含一導熱膠，係置於金屬框及基板之間，以提供光源散熱機制。此外，顯示器模組更包含一反射板，係置於金屬框及導光板之間。顯示器模組更包含一反射膜，係置於基板及導光板之間。In another embodiment, the display module further includes a thermal conductive adhesive disposed between the metal frame and the substrate to provide a heat dissipation mechanism for the light source. In addition, the display module further includes a reflector disposed between the metal frame and the light guide plate. The display module further includes a reflective film disposed between the substrate and the light guide plate.
於又一實施例，顯示器模組更包含一墊材，係相對於光源置於導光板之另一端上，以輔助承靠顯示面板。In still another embodiment, the display module further includes a mat disposed on the other end of the light guide plate with respect to the light source to assist the display panel.
本發明揭露一種顯示器模組，係能利用承載光源之基板並配合金屬框之應用，而達到承靠顯示面板並增進散熱效果，以簡化結構降低製造成本。為了使本發明之敘述更加詳盡與完備，本發明之上述及其他面向、特徵及優勢將在以下各種更特定之範例實施例的詳述及伴隨圖式下更易明瞭，其中相同的參考編號通常表示本發明之範例實施例中的相同構件。另外並需瞭解的是，本發明並不限於特定實施例的細節描述，且為清楚說明各元件並未依比例繪示。The invention discloses a display module which can utilize the substrate carrying the light source and cooperate with the application of the metal frame to achieve the bearing panel and improve the heat dissipation effect, so as to simplify the structure and reduce the manufacturing cost. The above and other aspects, features, and advantages of the present invention will become more apparent from The same components in the exemplary embodiments of the present invention. It is further to be understood that the invention is not limited to the details
圖3係根據本發明一實施例繪示之顯示器模組100之部份截面示意圖。於此實施例中，顯示器模組100係可用於筆記型 電腦之顯示面板與背光模組的整合或任何適當之電子產品的整合。如圖3所示，顯示器模組100包含導光板102、光源104、基板106、及金屬框108。於此實施例中，光源104係配置於導光板102之一端，而構成側向式之背光模組。光源104可為由單一發光單元或多個發光單元所組成之光源，其中發光單元如發光二極體、冷陰極燈管等，但不以此為限。導光板102係用以導引光源104所提供的光束。基板106係供設置光源104，且基板106部分延伸於導光板102上方，以供承靠一顯示面板120。舉例而言，基板106可為導熱性佳的硬式基板，例如包含金屬材質之基板，以作為光源(如發光二極體)的散熱基板。光源104係置於基板106之第一部份106a上，而後將基板106倒置於導光板102上，使得基板106載有光源104之第一部份106a突出於導光板102之一端，而基板106之第二部份106b係延伸於導光板102上方。如此一來，顯示面板120即可承靠於基板106之第二部份106b置於導光板102上方，而無需習知塑料框所提供的額外承靠面。因此，本發明藉由承載光源104之基板106同時用以承靠顯示面板120，可具有簡化整體結構減少製造成本之功效，同時解決習知使用塑料框的設計極限問題，亦可免除習知塑料框變形所衍生的干涉問題。此外，利用包含金屬材質之基板106之熱傳導及延展的特性，有助於配合光學膜118所需的容置空間(d)設計適當的基板厚度，而可達到薄化的功效。FIG. 3 is a partial cross-sectional view of a display module 100 according to an embodiment of the invention. In this embodiment, the display module 100 can be used for a notebook type. Integration of the display panel of the computer with the backlight module or integration of any suitable electronic product. As shown in FIG. 3 , the display module 100 includes a light guide plate 102 , a light source 104 , a substrate 106 , and a metal frame 108 . In this embodiment, the light source 104 is disposed at one end of the light guide plate 102 to form a lateral backlight module. The light source 104 may be a light source composed of a single light-emitting unit or a plurality of light-emitting units, such as a light-emitting diode, a cold cathode light tube, or the like, but not limited thereto. The light guide plate 102 is used to guide the light beam provided by the light source 104. The substrate 106 is provided with a light source 104, and the substrate 106 extends partially above the light guide plate 102 for bearing against a display panel 120. For example, the substrate 106 may be a hard substrate with good thermal conductivity, such as a substrate including a metal material, as a heat dissipation substrate of a light source such as a light emitting diode. The light source 104 is disposed on the first portion 106a of the substrate 106, and then the substrate 106 is placed on the light guide plate 102 such that the first portion 106a of the substrate 106 carrying the light source 104 protrudes from one end of the light guide plate 102, and the substrate 106 The second portion 106b extends above the light guide plate 102. In this way, the display panel 120 can be placed on the second portion 106b of the substrate 106 above the light guide plate 102 without the need for an additional bearing surface provided by the conventional plastic frame. Therefore, the present invention can reduce the manufacturing cost by simplifying the overall structure and reducing the manufacturing cost by using the substrate 106 carrying the light source 104 at the same time to support the display panel 120, and at the same time solving the design limitation problem of the conventional plastic frame, and also eliminating the conventional plastic. The interference problem derived from the deformation of the frame. In addition, by utilizing the characteristics of heat conduction and extension of the substrate 106 including the metal material, it is helpful to match the accommodating space (d) required for the optical film 118 to design an appropriate substrate thickness, thereby achieving the effect of thinning.
再者，金屬框108供容設導光板102、光源104、及基板 106。如圖3所示，金屬框108包含一主體108a及一反折上緣108b，其中主體108a供容設導光板102，而反折上緣108b係由主體108a直立延伸反折以部份包覆基板106。亦即，基板106未被金屬框108之反折上緣108b包圍的部份(即第二部份106b)係供承靠顯示面板120。如此一來，光源104藉由基板106與金屬框108接觸，而可進一步增進散熱的功效。Furthermore, the metal frame 108 is provided with a light guide plate 102, a light source 104, and a substrate. 106. As shown in FIG. 3, the metal frame 108 includes a main body 108a and a reverse upper edge 108b. The main body 108a is for receiving the light guide plate 102, and the reverse upper edge 108b is partially extended by the main body 108a. Substrate 106. That is, the portion of the substrate 106 that is not surrounded by the folded upper edge 108b of the metal frame 108 (ie, the second portion 106b) is intended to bear against the display panel 120. In this way, the light source 104 is in contact with the metal frame 108 by the substrate 106, and the heat dissipation effect can be further enhanced.
此外，本發明之顯示器模組100更可包含一導熱膠110，係置於金屬框108及基板106之間，以提供光源104更佳的散熱機制。舉例而言，如圖3所示，導熱膠110可貼附於基板106相應於金屬框反折上緣108b之部份的背面，使得光源104所產生的熱能經由基板106及導熱膠110傳遞至金屬框108之反折上緣108b，而提高散熱效率。相較於習知額外加入導電膠於基板下方而需增加金屬背框的厚度而言，本發明之配置方式係因基板106置於導光板102之上方，即使基板厚度或導熱膠厚度些許增加，亦不影響模組總厚度而可符合電子裝置整合薄化的需求。In addition, the display module 100 of the present invention further includes a thermal adhesive 110 disposed between the metal frame 108 and the substrate 106 to provide a better heat dissipation mechanism for the light source 104. For example, as shown in FIG. 3, the thermal conductive adhesive 110 can be attached to the back surface of the portion of the substrate 106 corresponding to the upper edge 108b of the metal frame, so that the thermal energy generated by the light source 104 is transmitted to the substrate 106 and the thermal conductive adhesive 110. The metal frame 108 is folded back to the upper edge 108b to improve heat dissipation efficiency. The arrangement of the present invention is such that the substrate 106 is placed above the light guide plate 102 even if the thickness of the metal back frame is increased by adding the conductive paste to the underside of the substrate. Even if the thickness of the substrate or the thickness of the thermal conductive paste is slightly increased, It also does not affect the total thickness of the module and can meet the needs of the integration and thinning of electronic devices.
於另一實施例，本發明之顯示器模組100更可選擇性地包含一反射板112，以反射光源104所提供的光束。舉例而言，如圖3所示，反射板112係置於金屬框108及導光板102之間。詳言之，反射板112係置於金屬框108之主體108a與導光板102之間，如此一來，光源104所提供的光束可藉由導光板102導引至顯示面板120，同時更可藉由反射板112將朝向金屬框 主體108a的光束反射回顯示面板120而增進光束的利用率。In another embodiment, the display module 100 of the present invention further optionally includes a reflector 112 to reflect the light beam provided by the light source 104. For example, as shown in FIG. 3, the reflector 112 is disposed between the metal frame 108 and the light guide plate 102. In detail, the reflector 112 is disposed between the main body 108a of the metal frame 108 and the light guide plate 102. Thus, the light beam provided by the light source 104 can be guided to the display panel 120 by the light guide plate 102, and at the same time, The reflector 112 will face the metal frame The light beam of the body 108a is reflected back to the display panel 120 to enhance the utilization of the light beam.
於另一實施例，本發明之顯示器模組100更可選擇地包含一反射膜114，以反射光源104所提供的光束。舉例而言，如圖3所示，反射膜114係置於基板106及導光板102之間。詳言之，反射膜114係置於基板106之第二部份106b與導光板102之間，如此一來，光源104所提供的光束可藉由導光板102導引至顯示面板120，同時更可藉由反射膜114將朝向基板106的光束反射回導光板102進而再導向顯示面板120，而增進光束的利用率。In another embodiment, the display module 100 of the present invention further optionally includes a reflective film 114 to reflect the light beam provided by the light source 104. For example, as shown in FIG. 3, the reflective film 114 is disposed between the substrate 106 and the light guide plate 102. In detail, the reflective film 114 is disposed between the second portion 106b of the substrate 106 and the light guide plate 102. Thus, the light beam provided by the light source 104 can be guided to the display panel 120 by the light guide plate 102, and at the same time The light beam toward the substrate 106 can be reflected back to the light guide plate 102 by the reflective film 114 to be redirected to the display panel 120, thereby improving the utilization of the light beam.
參考圖4A及4B，係根據本發明一實施例繪示之顯示器模組100之其他部份截面示意圖。舉例而言，圖4A及4B係顯示本發明之顯示器模組100中未包含基板106之其餘部份。亦即，以側向式背光模組為例，承載有光源104之基板106(如圖3之部份截面所示)係置於導光板102之一端，而導光板相對於光源104之另一端通常並無光源設置。如此將使得顯示面板120於該端缺乏承靠。有鑑於此，本發明之顯示器模組100更可包含一墊材116，係相對於光源104置於導光板104之另一端上，以輔助承靠顯示面板120，如圖4A所示。在此需注意，墊材116係相對於光源104，可設置於導光板102上任何需要提供顯示面板120進一步承靠的位置。舉例而言，墊材116可為一片或多個橡膠元件，且可設置於對應顯示面板之導光板周緣上，以提供顯示面板的進一步承靠。再者，如圖4A 所示，當墊材116設置於導光板102上用以承靠顯示面板120時，金屬框108對應之位置並不一定需要設計有反折上緣，而可有多樣化的設計，例如直立式包圍導光板102、墊材116及顯示面板120之側邊。此外，墊材116的設置方式不以圖4A所示為限。舉例而言，藉由變化金屬框108的設計，墊材116可設計成置於導光板102及金屬框108之相應反折上緣之間，且墊材116具有突出於金屬框108反折上緣的延伸部份可進一步供顯示面板120承靠，如圖4B所示。4A and 4B are cross-sectional views showing other parts of the display module 100 according to an embodiment of the invention. For example, FIGS. 4A and 4B show the remaining portion of the display module 100 of the present invention that does not include the substrate 106. That is, in the case of the lateral backlight module, the substrate 106 carrying the light source 104 (shown in part in cross section of FIG. 3) is placed at one end of the light guide plate 102, and the other end of the light guide plate is opposite to the light source 104. There is usually no light source setting. This will cause the display panel 120 to lack bearing at this end. In view of this, the display module 100 of the present invention may further include a mat 116 disposed on the other end of the light guide plate 104 with respect to the light source 104 to assist the display panel 120, as shown in FIG. 4A. It should be noted that the mat 116 is opposite to the light source 104 and can be disposed on the light guide plate 102 at any position where the display panel 120 needs to be further supported. For example, the mat 116 may be one or more rubber elements and may be disposed on the periphery of the light guide plate of the corresponding display panel to provide further bearing of the display panel. Again, as shown in Figure 4A As shown, when the mat 116 is disposed on the light guide plate 102 for bearing against the display panel 120, the corresponding position of the metal frame 108 does not necessarily need to be designed with a reverse upper edge, but may have various designs, such as an upright type. The side of the light guide plate 102, the mat 116 and the display panel 120 are surrounded. Further, the manner in which the mat 116 is disposed is not limited to that shown in FIG. 4A. For example, by changing the design of the metal frame 108, the mat 116 can be designed to be placed between the respective upper edges of the light guide plate 102 and the metal frame 108, and the mat 116 has a protrusion that protrudes from the metal frame 108. The extended portion of the rim can be further supported by the display panel 120, as shown in Figure 4B.
以上所述僅為本發明之較佳實施例而已，並非用以限定本發明之申請專利範圍；凡其它未脫離本發明所揭示之精神下所完成之等效改變或修飾，均應包含在下述之申請專利範圍內。The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention; all other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the following.
