Generally, according to the manner in which the backlights are combined with respect to the relative positions of the backlight modules, the backlight module can be generally used as a side person to pull the light and a direct reading module. The light source of the side-lit backlight module is located on the side of the backlight module, and since the light source of the direct-lit greedy module is located on the lower side of the backlight module, the side-input type is under the same size condition. The thickness of the backlight module is often thinner than the thickness of the direct type backlight module.习 The conventional edge-lit backlight module utilizes a light-emitting element such as a cold cathode fluorescent lamp (CCFL) or a light-emitting diode (Light Emitting Di) located on the side of the backlight module. 〇de, LED) produces a visible light source.

The following component codes are described in the application No. 50 of the survey period. This fixing method achieves the purpose of fixing the reflective sheet and the light guide plate by the circuit substrate of the light-emitting diode. Double-sided tape - end _ table off _ split-light two-pole _ circuit substrate and light guide plate adhesion 'the other end of the two-side off the female reflective sheet and the frame that accommodates the backlight module components. The area of the adhesive material on the double-sided tape is the same. However, the thickness of the gap between the thickness of the circuit substrate of the light-emitting diode and the thickness of the double-sided tape may be caused by the thickness of the gap. In this way, part of the light emitted by the light source is more likely to pass through the gap between the reflective sheet and the light guide plate, thereby causing a decrease in the light. Further, since the combination is complicated, the second G〇743 is requested.

However, the contact area of the double-sided metal thin side and the anti-riding side of the double-sided adhesive metal film depends on the thickness of the double-sided adhesive metal film. In the above-mentioned voids, without any matter in the position where the gap and the reflective layer are present, the arrangement of the double-sided adhesive metal film and the reflective layer tends to be unstable. In the prior art, the method of reflecting the plate and guiding the profile has the advantages of lowering the light source, lowering the fixing method, and fixing the hybrid material, so that the manufacturing cost is still special. ® [Summary of the Invention] 3 In view of the above problems, the object of the present invention is to provide a backlight module and an optical device including the backlight module, and to improve the assembly efficiency of the optical module by using the light-reflecting plate of the reflector.
