Description

顯示器 monitor

本發明涉及一種帶有散熱模組的顯示器。 The invention relates to a display with a heat dissipation module.

隨著科技的發展，顯示器的背光模組的發光二極體(Light-emitting diode,LED)越做越小，而亮度越來越高。從而使得其熱源越來越集中，並形成點狀熱源，不利於散熱。 With the development of science and technology, the light-emitting diode (LED) of the backlight module of the display is getting smaller and smaller, and the brightness is getting higher and higher. As a result, its heat source is more and more concentrated, and a point-shaped heat source is formed, which is not conducive to heat dissipation.

有鑑於此，有必要提供一種帶有散熱模組的顯示器。 In view of this, it is necessary to provide a display with a heat dissipation module.

一種顯示器，包括背光模組，所述顯示器還包括散熱模組，所述散熱模組包括散熱件及緩衝件，所述散熱件為片狀的散熱材料，所述散熱件設置於所述背光模組的下表面，所述緩衝件為自帶粘性與彈性的柔軟材料，所述緩衝件藉由自身粘性直接粘設於所述散熱件上，以將所述散熱件固定於所述背光模組上。 A display includes a backlight module. The display further includes a heat dissipation module. The heat dissipation module includes a heat dissipation element and a buffer element. The heat dissipation element is a sheet-shaped heat dissipation material. The heat dissipation element is disposed on the backlight module. The lower surface of the group, the buffer member is a soft material with self-adhesive and elasticity, and the buffer member is directly adhered to the heat sink by its own viscosity to fix the heat sink to the backlight module on.

上述顯示器中，所述緩衝件藉由自身粘性直接將所述散熱件粘設於所述背光模組上，無需再使用背膠，可有效減少所述顯示器的厚度，並降低其成本。同時，所述緩衝件為彈性的柔軟材料，相較於將一泡棉層藉由背膠貼合於所述背光模組上，其貼合更加平整，不會產生氣泡，避免了所述顯示器產生水波紋，且緩衝效果較好。 In the above display, the buffering member directly adheres the heat dissipating member to the backlight module by virtue of its own adhesiveness, without using adhesive, which can effectively reduce the thickness of the display and reduce its cost. At the same time, the cushioning member is an elastic and soft material. Compared with the application of a foam layer to the backlight module by adhesive, the bonding is smoother, no bubbles are generated, and the display is avoided. Water ripples are generated and the buffering effect is better.

下面結合附圖，對本發明的一些實施方式作詳細說明。在不衝突的情況下，下述的實施例及實施例中的特徵可以相互組合。 The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

請參閱圖1，本發明第一較佳實施例提供一種顯示器100。所述顯示器100可為行動電話、電腦、電視或遊戲機等電子裝置的顯示幕。所述顯示器100至少包括顯示面板11、背光模組10及散熱模組20。 Please refer to FIG. 1, a first preferred embodiment of the present invention provides a display 100. The display 100 may be a display screen of an electronic device such as a mobile phone, a computer, a TV or a game console. The display 100 at least includes a display panel 11, a backlight module 10 and a heat dissipation module 20.

所述顯示面板11可以為液晶顯示面板。所述背光模組10設置於所述顯示面板11下方。所述背光模組10包括導光板101、光源103及反射片105。所述光源103與導光板101相鄰設置。在本實施例中，所述光源103為點狀光源，例如發光二極體，從而所述光源103產生點狀熱源。所述反射片105直接設置於所述導光板101遠離所述顯示面板11的一表面。 The display panel 11 may be a liquid crystal display panel. The backlight module 10 is disposed below the display panel 11. The backlight module 10 includes a light guide plate 101, a light source 103, and a reflective sheet 105. The light source 103 is arranged adjacent to the light guide plate 101. In this embodiment, the light source 103 is a point light source, for example As a light emitting diode, the light source 103 generates a point-shaped heat source. The reflective sheet 105 is directly disposed on a surface of the light guide plate 101 away from the display panel 11.

請一併參閱圖2與圖3，圖2是所述散熱模組20的側視結構示意圖，圖3是所述散熱模組20的俯視結構示意圖。所述散熱模組20包括散熱件21及緩衝件23。所述散熱件21呈片狀，所述散熱件21直接設置於所述反射片105遠離所述導光板101的一表面，且對應所述光源103設置。也就是說，所述散熱件21設置於所述光源103遠離所述顯示面板11的一側。在本實施例中，所述散熱件21的尺寸小於所述反射片105的尺寸。當然，在其他實施例中，也可調整所述散熱件21的形狀及尺寸，只要滿足所述散熱件21的面積大於所述光源103的面積均可。 Please refer to FIG. 2 and FIG. 3 together. FIG. 2 is a schematic structural side view of the heat dissipation module 20, and FIG. 3 is a schematic structural top view of the heat dissipation module 20. The heat dissipation module 20 includes a heat dissipation component 21 and a buffer component 23. The heat dissipation member 21 is in the shape of a sheet. The heat dissipation member 21 is directly disposed on a surface of the reflective sheet 105 away from the light guide plate 101 and corresponding to the light source 103. In other words, the heat dissipation member 21 is disposed on the side of the light source 103 away from the display panel 11. In this embodiment, the size of the heat sink 21 is smaller than the size of the reflective sheet 105. Of course, in other embodiments, the shape and size of the heat sink 21 can also be adjusted, as long as the area of the heat sink 21 is larger than the area of the light source 103.

在本實施例中，所述散熱件21為片狀的散熱材料。如此，所述散熱件21可使得所述光源103產生的點狀熱源的熱量擴散開來，以實現降溫，從而解決點狀熱源的散熱問題。為了提高所述散熱件21的散熱性能，所述散熱件21可以由石墨片或銅箔等熱傳導性能較好的散熱材料製成。較佳的，所述散熱件21的厚度範圍為0.01mm~0.2mm。 In this embodiment, the heat sink 21 is a sheet-shaped heat sink material. In this way, the heat dissipation member 21 can diffuse the heat of the point heat source generated by the light source 103 to achieve temperature reduction, thereby solving the heat dissipation problem of the point heat source. In order to improve the heat dissipation performance of the heat dissipation member 21, the heat dissipation member 21 may be made of a heat dissipation material with better thermal conductivity such as graphite sheet or copper foil. Preferably, the thickness of the heat dissipation member 21 ranges from 0.01 mm to 0.2 mm.

所述緩衝件23大致呈片狀。所述緩衝件23直接設置於所述散熱件21與所述反射片105遠離所述導光板101的表面。在本實施例中，所述緩衝件23的形狀及尺寸與所述顯示面板11大致匹配。所述緩衝件23由自帶微粘性與彈性的柔軟材料製成。如此，所述緩衝件23藉由其粘性作用粘貼至所述散熱件21與所述反射片105遠離所述導光板101的表面。例如，當所述散熱件21的尺寸小於所述反射片105的尺寸時，所述緩衝件23對應所述散熱件21的部分直接與所述散熱件21的遠離所述導光板101的表面粘貼接觸，而其他部分則直接與所述反射片105的遠離所述導光板101的表面粘貼接觸。 The buffer member 23 is generally in the shape of a sheet. The buffer member 23 is directly disposed on the surface of the heat dissipating member 21 and the reflective sheet 105 away from the light guide plate 101. In this embodiment, the shape and size of the buffer 23 substantially match the display panel 11. The buffer member 23 is made of a soft material with slight viscosity and elasticity. In this way, the buffer member 23 is adhered to the surface of the heat dissipating member 21 and the reflective sheet 105 away from the light guide plate 101 by its adhesive effect. For example, when the size of the heat sink 21 is smaller than the size of the reflective sheet 105, the portion of the buffer member 23 corresponding to the heat sink 21 is directly pasted to the surface of the heat sink 21 away from the light guide plate 101 The other parts are directly in contact with the surface of the reflective sheet 105 away from the light guide plate 101.

在本實施例中，所述緩衝件23為自帶微粘性的泡棉，例如亞克力泡棉。在本實施例中，所述緩衝件23的粘度範圍為0.01N/25mm~3N/25mm，即將標準長度為25mm的所述緩衝件23撕下來時所需的力值。 In this embodiment, the buffer member 23 is a self-adhesive foam, such as acrylic foam. In this embodiment, the buffer 23 has a viscosity ranging from 0.01 N/25 mm to 3 N/25 mm, that is, the force value required when the buffer 23 having a standard length of 25 mm is torn off.

可以理解，在本實施例中，所述緩衝件23藉由自身粘性直接將所述散熱件21粘設於所述反射片105上，且對應所述光源103設置。如此，可使得所述光源103產生的點狀熱源被均勻散熱，且不需要額外背膠，可以有效減少所述顯示器100的厚度並降低其製作成本。另外，由於所述緩衝件23自帶的微粘性特性，使得所述緩衝件23很容易從所述背光模組10上撕下，因此重工容易。同時，所述緩衝件23為彈性的柔軟材料，相較於將泡棉層藉由背膠貼合於所述散熱件21及所述反射片105上，其貼合更加平整，不會產生氣泡，避免了所述顯示器100產生水波紋，且緩衝效果較好。其次，所述緩衝件23熱脹冷縮不明顯，因此不會限制所述反射片105的熱膨脹。 It can be understood that, in this embodiment, the buffer member 23 directly adheres the heat dissipating member 21 to the reflective sheet 105 by virtue of its own viscosity, and is disposed corresponding to the light source 103. In this way, the point-shaped heat source generated by the light source 103 can be uniformly dissipated, and no additional glue is needed, which can effectively reduce the thickness of the display 100 and reduce its manufacturing cost. In addition, due to the micro-adhesive characteristic of the buffer member 23, the buffer member 23 can be easily torn off from the backlight module 10, so the rework is easy. At the same time, the buffer member 23 is an elastic and soft material. Compared with the foam layer attached to the heat dissipating member 21 and the reflective sheet 105 by adhesive, the bonding is smoother and no bubbles are generated. , To avoid water ripples on the display 100, and the buffer effect is better. Secondly, the thermal expansion and contraction of the buffer member 23 is not obvious, so the thermal expansion of the reflective sheet 105 is not limited.

請參閱圖4，本發明的第二較佳實施例提供一種顯示器200。所述顯示器200包括顯示面板11、背光模組10及散熱模組20。可以理解，所述顯示器200與顯示器100的不同之處在於所述顯示器200還包括金屬框106。所述金屬框106包括底板107以及側框108。所述底板107直接設置於所述反射片105遠離所述導光板101的一表面。所述側框108設置於所述底板107的周緣，與所述底板107大致垂直，並由所述底板107的周緣延伸。如此，所述側框108與所述底板107共同圍成一收容部109，以***述導光板101、所述光源103及所述反射片105。 Please refer to FIG. 4, a second preferred embodiment of the present invention provides a display 200. The display 200 includes a display panel 11, a backlight module 10 and a heat dissipation module 20. It can be understood that the difference between the display 200 and the display 100 is that the display 200 further includes a metal frame 106. The metal frame 106 includes a bottom plate 107 and side frames 108. The bottom plate 107 is directly disposed on a surface of the reflective sheet 105 away from the light guide plate 101. The side frame 108 is provided on the peripheral edge of the bottom plate 107, is substantially perpendicular to the bottom plate 107, and extends from the peripheral edge of the bottom plate 107. In this way, the side frame 108 and the bottom plate 107 together define an accommodating portion 109 for accommodating the light guide plate 101, the light source 103 and the reflective sheet 105.

在本實施例中，所述散熱件21直接設置於所述底板107遠離所述反射片105的一表面。所述緩衝件23粘貼設置於所述散熱件21及所述底板107遠離所述反射片105的表面。例如，所述緩衝件23對應所述散熱件21的部分直接與所述散熱件21的遠離所述反射片105的表面粘貼接觸，其他部分則直接與所述底板107的遠離所述反射片105的表面粘貼接觸。 In this embodiment, the heat dissipation member 21 is directly disposed on a surface of the bottom plate 107 away from the reflective sheet 105. The buffer member 23 is pasted on the surface of the heat sink 21 and the bottom plate 107 away from the reflective sheet 105. For example, the portion of the buffer member 23 corresponding to the heat dissipation member 21 is directly in contact with the surface of the heat dissipation member 21 away from the reflection sheet 105, and the other portion is directly in contact with the bottom plate 107 away from the reflection sheet 105 Pasted on the surface.

顯然，本發明的顯示器100/200中，所述緩衝件23藉由自身粘性直接將所述散熱件21粘設於所述反射片105或者所述金屬框106遠離所述導光板101的一表面，無需再使用背膠，可有效減少所述顯示器100/200的厚度，並降低其成本。同時，所述緩衝件23為彈性的柔軟材料，相較於將一泡棉層藉由背膠貼合於所述背光模組10上，其貼合更加平整，不會產生氣泡，避免了所述顯示器100/200產生水波紋，且緩衝效果較好。 Obviously, in the display 100/200 of the present invention, the buffer member 23 directly adheres the heat dissipating member 21 to a surface of the reflective sheet 105 or the metal frame 106 away from the light guide plate 101 by its own adhesiveness No need to use adhesive, which can effectively reduce the thickness of the display 100/200 and reduce its cost. At the same time, the cushioning member 23 is an elastic and soft material. Compared with applying a foam layer to the backlight module 10 by adhesive, the bonding is smoother, and no bubbles are generated, which avoids all The display 100/200 produces water ripples, and the buffering effect is better.
