Description
本發明涉及一種背光模組之組裝方法、背光模組及液晶顯示裝置。 The invention relates to a method for assembling a backlight module, a backlight module and a liquid crystal display device.
液晶顯示裝置因具有低輻射性、體積輕薄短小及耗電低等特點，已廣泛應用於手機、個人數位助理、筆記型電腦、個人電腦及電視等領域。由於液晶顯示裝置的液晶面板本身不具有發光特性，因此，為達到顯示效果，需要給液晶面板提供一背光模組以向液晶面板提供亮度充分且分佈均勻的平面光，從而實現液晶顯示裝置的顯示功能。 Liquid crystal display devices have been widely used in mobile phones, personal digital assistants, notebook computers, personal computers and televisions due to their low radiation, small size, short power consumption and low power consumption. Since the liquid crystal panel of the liquid crystal display device does not have the light-emitting property itself, in order to achieve the display effect, it is necessary to provide a backlight module to the liquid crystal panel to provide planar light with sufficient brightness and uniform distribution to the liquid crystal panel, thereby realizing display of the liquid crystal display device. Features.
通常背光模組主要包括導光板、光源、反射片以及一至多個光學膜片。光源通常為點光源或者線光源，在背光模組中用於提供光線。導光板則用於引導光線的方向，並達到亮度均勻的效果，從而為液晶面板提供分佈均勻的平面光。點光源如發光二極體(LED)因其節能、環保的優點越來越多地被應用於背光模組中用於提供光線，中大尺寸的液晶面板常採用多顆點光源排列成線狀的光源帶(Light bar)來取代傳統的線光源，如冷陰極燈管(CCFL)。 Generally, the backlight module mainly includes a light guide plate, a light source, a reflective sheet, and one or more optical films. The light source is usually a point source or a line source for providing light in the backlight module. The light guide plate is used to guide the direction of the light and achieve a uniform brightness, thereby providing a uniform distribution of planar light to the liquid crystal panel. Point light sources such as light-emitting diodes (LEDs) are increasingly used in backlight modules for providing light due to their advantages of energy saving and environmental protection. Medium and large-sized liquid crystal panels are often arranged in a line by using multiple point sources. Light bar replaces traditional line sources such as cold cathode lamps (CCFLs).

When assembled, the flexible circuit board is folded at the boundary between the two first light source setting regions 423 and the second light source setting region 425 of the first surface, respectively, such that the first light source setting region 423 is disposed adjacent to the bottom surface of the light guide plate. The second light source setting area 425 is disposed adjacent to the light emitting surface of the light guide plate, and the light emitting diodes disposed in the first and second light source setting areas 423 and 425 are opposite to the light guide surface of the light guide plate. The second and third sides 4161, 4162, 4163 are set and Light is supplied to the first, second, and third sides 4161, 4162, and 4163.
請參閱圖9，是本發明背光模組第四實施方式的立體示意圖。本發明第四實施方式的背光模組與第一實施方式的背光模組的區別主要在於：該導光板的依次首尾相連的四個側面為入光面，分別為第一側面5161、第二側面5162、第三側面5163、第四側面5164。該軟性電路板的第一表面包括二第一光源設置區523和二第二光源設置區525，該第一光源設置區523和第二光源設置區525交替設置。組裝時，分別在第一光源設置區523和第二光源設置區525的交界處翻折該軟性電路板，以使得該第一光源設置區523鄰近該導光板的底面設置，而該第二光源設置區525鄰近該導光板的出光面設置，且設置在第一、第二光源設置區523、525的發光二極體正對導光板的作為入光面的第一、第二、第三、第四側面5161、5162、5163、5164設置並向第一、第二、第三、第四側面5161、5162、5163、5164提供光線。 Please refer to FIG. 9 , which is a perspective view of a fourth embodiment of a backlight module of the present invention. The backlight module of the fourth embodiment of the present invention is different from the backlight module of the first embodiment in that the four sides of the light guide plate that are connected end to end are the light incident surfaces, respectively being the first side 5161 and the second side. 5162, a third side 5163, and a fourth side 5164. The first surface of the flexible circuit board includes two first light source setting areas 523 and two second light source setting areas 525, and the first light source setting area 523 and the second light source setting area 525 are alternately disposed. When assembled, the flexible circuit board is folded at the boundary between the first light source setting area 523 and the second light source setting area 525, respectively, such that the first light source setting area 523 is disposed adjacent to the bottom surface of the light guide plate, and the second light source is disposed. The setting area 525 is disposed adjacent to the light emitting surface of the light guide plate, and the light emitting diodes disposed in the first and second light source setting areas 523 and 525 are opposite to the first, second, and third light receiving surfaces of the light guiding plate. The fourth side 5161, 5162, 5163, 5164 is disposed and provides light to the first, second, third, and fourth sides 5161, 5162, 5163, 5164.
請參閱圖10，是本發明液晶顯示裝置的示意圖。該液晶顯示裝置2包括液晶面板29及相對該液晶面板29設置的背光模組，該背光模組可採用上述實施例中的任意一背光模組。 Please refer to FIG. 10, which is a schematic diagram of a liquid crystal display device of the present invention. The liquid crystal display device 2 includes a liquid crystal panel 29 and a backlight module disposed opposite to the liquid crystal panel 29. The backlight module can adopt any one of the above embodiments.
然而，本案的背光模組不限於上述實施方式所述，例如，組裝時光源組時，可使得第一表面第一光源設置區鄰近該導光板的出光面設置，翻折後第一表面的第二光源設置區鄰近該導光板的底面設置，而設置在第一、第二光源設置區的發光二極體對應導光板的入光面設置。 However, the backlight module of the present invention is not limited to the above embodiment. For example, when assembling the light source group, the first surface first light source setting region may be disposed adjacent to the light emitting surface of the light guide plate, and the first surface of the first surface may be folded. The two light source setting areas are disposed adjacent to the bottom surface of the light guide plate, and the light emitting diodes disposed in the first and second light source setting areas are disposed corresponding to the light incident surface of the light guide plate.
