本发明涉及电子产品领域，具体而言，涉及一种侧光式液晶模组、一种直下式液晶模组及具有该侧光式液晶模组或直下式液晶模组的电视机。The present invention relates to the field of electronic products, in particular to a side-light liquid crystal module, a direct-type liquid crystal module and a television set having the side-light liquid crystal module or the direct-type liquid crystal module.
背景技术Background technique
现今在液晶模组的背光部分中多采用将LED灯焊接在长条形状的电路基板及一长条状的铝型材上以构成LED灯条，灯条背面与铝材散热板结合，形成发光二极管散热构造。然而，随着液晶电视尺寸的增大，LED灯数量的增加以及大功率、高亮度的集成LED芯片等陆续被开发出来，LED灯工作时所产生的热量正逐步上升，如不及时将这部分热量散出，不仅LED的发光度和寿命将会急剧下降，其周围的导光板等也会发生软化变形，因此，LED灯条的散热问题需有效解决，不可忽视。Nowadays, in the backlight part of the liquid crystal module, LED lamps are mostly welded to a long strip-shaped circuit board and a long strip of aluminum profile to form an LED light strip. The back of the light strip is combined with an aluminum heat sink to form a light-emitting diode. Thermal structure. However, with the increase in the size of LCD TVs, the increase in the number of LED lamps and the development of high-power, high-brightness integrated LED chips, etc., the heat generated by LED lamps is gradually increasing. When the heat is dissipated, not only the luminosity and life of the LED will drop sharply, but also the surrounding light guide plate will soften and deform. Therefore, the heat dissipation problem of the LED light bar must be effectively solved and cannot be ignored.
发明人在实现本发明的过程中发现：在现有技术中，LED的散热方式均为从LED一个方向通过散热结构传导出去，而且在液晶模组中，LED灯条的散热通常只是从背板一侧的方向散发，这种散热方式，使得LED灯条的热量散发较慢，不仅限制了LED灯的使用功率，降低LED灯的寿命，且可能会导致其周围的导光板等发生软化变形，使液晶模组所显示的画面受影响。In the process of realizing the present invention, the inventor found that: in the prior art, the heat dissipation of LED is conducted from one direction of the LED through the heat dissipation structure, and in the liquid crystal module, the heat dissipation of the LED light bar is usually only from the back plate Dissipate in the direction of one side. This heat dissipation method makes the heat dissipation of the LED light bar slower, which not only limits the power of the LED light, reduces the life of the LED light, but also may cause the surrounding light guide plate to soften and deform. The picture displayed by the liquid crystal module is affected.

灯条安装在散热板上，且灯条和散热板均与胶框相接触，通过在胶框与灯条、散热板和/或背板的连接处设置第一导热片，使灯条产生的一部分热量通过第一导热片传递至胶框上，经由胶框和面框散出，而灯条产生的另一部分热量通过散热板传递至背板上，经由背板散出，这样，通过第一导热片及散热板使灯条产生的全部热量分别由背板及背板相对侧两个方向传导出去，增强了散热效果，进而保证了灯条的发光度和使用寿命，并在使用大功率的灯条时，避免了灯条周围的导光板等出现受热软化变形的现象。The light bar is installed on the heat sink, and both the light bar and the heat sink are in contact with the plastic frame. By setting the first heat conduction sheet at the connection between the plastic frame and the light bar, the heat sink and/or the back plate, the light generated by the light bar A part of the heat is transferred to the plastic frame through the first heat conduction sheet, and dissipated through the plastic frame and the surface frame, while the other part of the heat generated by the light bar is transferred to the back plate through the heat sink plate, and then dissipated through the back plate.

进一步，第一导热片与第二导热片一体制成。Further, the first heat conduction sheet and the second heat conduction sheet are made integrally.
因胶框通常采用塑料材料制成，且在本实施例中面框采用金属材料制成，胶框的导热系数低于面框，为了进一步加强散热效果，在胶框与面框之间设置第二导热片，并使第一导热片和第二导热片相连接，使灯条产生的一部分热量由第一导热片、第二导热片依次传递至面框上，经由面框散出，而灯条产生的另一部分热量则通过散热板传递至背板上，这样，灯条产生的全部热量分别由背板及面框传导出去，增强了散热效果，进而保证了灯条的发光度和使用寿命，并在使用大功率的灯条时，避免了灯条周围的导光板等出现受热软化变形的现象，同时保证了液晶模组所显示的画面的质量。Since the plastic frame is usually made of plastic material, and the surface frame is made of metal material in this embodiment, the thermal conductivity of the plastic frame is lower than that of the surface frame. In order to further enhance the heat dissipation effect, a second Two heat conduction sheets, and connect the first heat conduction sheet and the second heat conduction sheet, so that a part of the heat generated by the light strip is transferred to the surface frame by the first heat conduction sheet and the second heat conduction sheet in turn, and dissipated through the surface frame, while the lamp The other part of the heat generated by the light bar is transferred to the back plate through the heat sink, so that all the heat generated by the light bar is conducted through the back plate and the front frame respectively, which enhances the heat dissipation effect and ensures the luminosity and service life of the light bar , and when using a high-power light bar, it avoids the phenomenon of softening and deformation of the light guide plate around the light bar, etc., and at the same time ensures the quality of the picture displayed by the liquid crystal module.

The direct contact between the graphite heat conduction sheet and the side of the LED light bar can effectively reduce the heat generated by the LED light bar. On this basis, since the thermal conductivity of the plastic plastic frame is lower than that of the metal surface frame, in order to conduct the heat emitted by the LED lamp through the graphite heat conduction sheet as soon as possible, the graphite heat conduction sheet is extended and attached to the plastic frame On the contact side with the metal surface frame, at the contact interface between the metal surface frame and the plastic frame, the graphite heat conduction sheet can be freely pasted on the plastic frame side or the metal surface frame side of the contact interface. In this way, the LED light bar is produced Part of the heat is exported through the graphite heat-conducting sheet and the metal surface frame, and the other part of the heat generated by the LED light bar is exported through the back plate through the heat sink, so that all the heat generated by the LED light bar is exported through the back plate and the opposite side of the back plate. , enhance the heat dissipation effect, thereby ensuring the luminosity and service life of the light bar, and avoiding the phenomenon of softening and deformation of the light guide plate around the light bar when using a high-power light bar.

A heat conduction sheet is arranged on the groove. In order not to affect the practicability of the plastic frame, the heat conduction sheet needs to be processed according to the shape of the through groove on the plastic frame.

对于直下式结构，LED灯在反射片之下直接贴附在背板上，背板为金属材质，其导热性能较好，如图6所示，在与胶框接触的背板的外侧以及胶框的外侧，贴附整条石墨导热片，使得灯条产生的部分热量经由背板、石墨导热片传导到面框，由面框散出，因在本实施例中面框与背板同样为金属材质，可进一步提高直下式液晶模组的散热效果。For the direct-type structure, the LED lamp is directly attached to the backboard under the reflector. The backboard is made of metal and has good thermal conductivity. On the outside of the frame, a whole piece of graphite heat conduction sheet is attached, so that part of the heat generated by the light strip is conducted to the front frame through the back plate and the graphite heat conduction sheet, and then dissipated from the front frame, because in this embodiment, the front frame and the back plate are also The metal material can further improve the heat dissipation effect of the direct-lit liquid crystal module.
实施例三：Embodiment three:
本实施例提供了一种电视机，包括上述任一实施例提供的侧光式液晶模组或者直下式液晶模组。This embodiment provides a TV, including the edge-lit liquid crystal module or the direct-lit liquid crystal module provided in any one of the above embodiments.
本实施例提供的电视机结构在附图中均未示出，其具有良好的散热性能，在侧光式液晶模组内设置导热片，并将该导热片与现今背板上应用的铝材散热板相结合使用，有效地将LED灯条产生的全部热量通过背板、胶框和面框传导出去，增强了散热效果，进而保证了灯条的发光度和使用寿命，避免了灯条周围的导光板等出现受热软化变形的现象，延长了电视机的使用寿命，并在不增加电视机厚度的同时，保证了电视机的画面质量，进而保证了观看效果，为用户提供了更好的视觉画面，提高了市场竞争力。The structure of the TV set provided by this embodiment is not shown in the accompanying drawings, and it has good heat dissipation performance. A heat conduction sheet is arranged in the side-light liquid crystal module, and the heat conduction sheet is combined with the aluminum material used on the current back plate. The combined use of the heat sink can effectively conduct all the heat generated by the LED light bar through the back plate, plastic frame and surface frame, which enhances the heat dissipation effect, thereby ensuring the luminosity and service life of the light bar, and avoiding the surrounding area of the light bar. The phenomenon of heat softening and deformation of the light guide plate, etc. prolongs the service life of the TV, and ensures the picture quality of the TV without increasing the thickness of the TV, thereby ensuring the viewing effect and providing users with better The visual picture improves the market competitiveness.
为了迎合市场需求，提高市场竞争力，多数厂家会不使用前壳，直接采用面框代替前壳，或者不使用面框，直接采用前壳代替面框。In order to meet market demand and improve market competitiveness, most manufacturers will directly replace the front shell with a face frame without using the front shell, or directly replace the front shell with a front shell without using the face frame.
因此，在本实施例提供的电视机中，所述前壳与面框可作为同一构件，即所述面框即为所述前壳。例如：当电视机中包括侧光式液晶模组时，则不使用前壳，直接使用面框作为前壳；当电视机中包括直下式液晶模组时，则不使用面框，直接使用前壳等，在此不再赘述，但其应用均应在本发明的保护范围之内。Therefore, in the television set provided in this embodiment, the front case and the front frame can be used as the same component, that is, the front case is the front case. For example: when the TV includes an edge-lit LCD module, the front cover is not used, and the front frame is directly used as the front cover; when the TV includes a direct-lit LCD module, the front frame is not used, and the front Shells, etc., will not be repeated here, but their applications should be within the protection scope of the present invention.
当然，面框及前壳也可以是两个不同构件，使用时将面框与前壳固定连接即可，对于面框及前壳的使用可根据不同情况和需求进行选择，在此不再赘述。Of course, the front frame and the front shell can also be two different components, and the front frame and the front shell can be fixedly connected during use. The use of the front frame and the front shell can be selected according to different situations and needs, so I won’t go into details here .
需要说明的是，因热传递是由于系统内或物体内温度不同而引起的，而且热量的自发传递总是由高温区传递到低温区，灯条发出的热量可以围绕以灯条为轴的圆柱向不同方向发散，而胶框在液晶模组中有两种设置方式，一种是设置于各种光学膜片之上，另一种是设置于各种光学膜片之下，起到固定背光系统的作用，在上述任一实施例中均采用的是胶框设置于光学膜片之上的方式，但采用无论哪种设置方式，都可以采用上述任一实施例提供的技术方案，将灯条产生的全部热量从背板及背板相对侧两个方向传导出去，解决灯条的散热问题，在此不再赘述，但其应用均应在本发明的保护范围之内。It should be noted that since the heat transfer is caused by the temperature difference in the system or in the object, and the spontaneous transfer of heat is always transferred from the high temperature area to the low temperature area, the heat emitted by the light bar can surround the cylinder with the light bar as the axis Diverge in different directions, and there are two ways to set the plastic frame in the liquid crystal module, one is set on various optical films, and the other is set under various optical films to fix the backlight For the function of the system, in any of the above-mentioned embodiments, the plastic frame is set on the optical film, but no matter which setting method is used, the technical solution provided by any of the above-mentioned embodiments can be used to place the lamp All the heat generated by the light bar is conducted from the back plate and the opposite side of the back plate to solve the heat dissipation problem of the light bar, which will not be repeated here, but its application should be within the protection scope of the present invention.
