Thin-film transistor Lu liquid crystal display has gradually replaced CRT display and has become the trend of mainstream electronic products. L. Because f-film transistor liquid crystal display has lightness, power saving and no The advantages of ray, etc., have been applied to various electronic products, including personal digital assistants, mobile phones, digital cameras, and digital cameras, including small-sized panels, as well as displays and notebooks using large-sized panels. Telephone and TV. However, since the thin film transistor liquid crystal panel belongs to the self-luminous surface 7F device, the backlight of the backlight panel can be displayed regardless of the large and large size of the panel, and the information of the back surface of the liquid crystal panel can be displayed. Please refer to the first figure and the second figure, which are schematic diagrams of the prior art applied to the backlight module 1 , which includes a light guide plate U... frame 12 and a flexible circuit board l3 (Flexible Printed Ci rcui t , FPC) 'the light guide plate 1 1 is a light-transmissive acrylic plate, the upper surface of which is the light-emitting surface iii, the lower surface thereof is combined with the frame i 2 , and one side surface of the light guide plate 11 Then, it is a light incident surface ii 2, and a reflecting plate 14 is disposed between the frame 2 and the lower surface. One side surface of the flexible circuit board 13 is provided with two light-emitting diodes (LEDs) 15 as light sources, wherein the light-emitting diodes i 5 are semiconductor light-emitting elements such as gallium phosphide (GAP) and gallium arsenide ( A component such as G a A s ), by means of M307134: a soft circuit board 13 applies a current to the light-emitting diode 15 to convert electrical energy into light energy to achieve the effect of illuminating. The number of the light-emitting diodes 15 can be appropriately increased or decreased or the position is adjusted according to the size of the light guide plate 11 and the actual light source. After entering the light guide plate ii, the light emitted by the light-emitting diode 15 is outputted by the light-emitting surface 111 of the light guide plate 11 after being scattered by the light guide plate 11 and reflected by the reflection plate 14 to assist the liquid crystal panel (not shown) The flexible circuit board 13 and the non-light source exit surface of the light guide plate 丄i are provided with a bonding material 16 to connect the light guide plate 11 and the flexible circuit board 13 to the plurality of light emitting diodes 15 Positioning: However, the structure of the adhesive material i 4, as shown in the first figure, is in the form of a strip, disposed between the light guide plate 1 1 and the flexible circuit board i 3 , so when each light-emitting diode 1 5 After the emitted light passes through the adhesive material χ 6, the exit angle of the line is changed, or part of the light is received by the adhesive material, and the light output of the light source is also reduced, which also reduces the brightness of the backlight module. And will change the display effect of the LCD display.曰 In theory, the light-emitting surface of the light-emitting diode 15 must be close to the light guide plate 101 1 2, so that the light can directly enter the light guide plate 1 1 to improve the utilization rate of the light source. However, in practice, the backlight module i will have tolerances, and the purpose is mainly to avoid problems such as poor formation of each V. However, the backlight module 1 θ ^ of the prior art has a gap a between the light-emitting diode 15 and the light guide plate 1 1 , and the light source loss exceeds 1 〇% when the gap A is larger than 〇·5 mm. Above, and the larger the θ gap A, the more the loss of the light source. How to improve the shortcomings of the polar body technology to reduce the gap between the light-emitting diodes and the light-emitting plate, so that the light-emitting diodes 15 abut against the light-incident surface of the light guide plate to improve the light source of the backlight module The utilization rate is actually the current research and development of M307134: the task that the personnel want to solve. [New content] This creation is related to the edge-lit backlight module architecture, which is used to assemble and position the light guide plate and the light source. The purpose is to provide a plurality of light source positioning, and the light source can be placed close to the light guide plate. On the surface, the light source device for improving the light source utilization of the backlight module is further improved. The "light source fixing device" of the present invention has a plurality of light sources disposed on a side of the Φ light incident surface of the light guide plate; wherein the light guide plate and the light source are provided with fixing means, and the fixing device is formed by extending the light guide plate to The light guide plate and the light source are assembled and positioned with each other, so that not only the plurality of light sources can be positioned, but also the light sources can be closely abutted on the light incident surface of the light guide plate. [Embodiment] In order to enable the examiner to understand the structural composition of the creation, and The overall operation mode is as follows: The “Light Source Fixing Device” is mainly used to improve the light source device in the edge-lit backlight module structure. As shown in the third and fourth figures, the same is true. A plurality of light sources are disposed on one side of the light incident surface 21 1 of the light guide plate 2 1 , and the plurality of light sources 2 2 may be light emitting diodes, so that the light of the light source 22 is incident on the light guide plate 21 from the light incident surface 211 and The light exiting surface 212 of the light guide plate 21 is emitted to achieve the effect of the light source display.
