Description

  The present invention relates to a light source assembly.

In the backlight module, a light bar fixing method is gradually improved in consideration of technology and cost. Early light bars are fixed to the backplate in a screw-fixed manner using a thermal pad, and are now usually fixed to the backplate in a viscous-bonded manner. As shown in light source assembly 100 of FIG. 1, light bar 104 is attached to a thermally conductive double-sided adhesive tape (thermal).
tape) 106 and bonded and fixed to the back plate 102. However, when the heat conductive double-sided adhesive tape 106 is used, the problem of peeling or dropping is likely to occur. When peeling occurs at one end of the thermally conductive double-sided adhesive tape 106 between the light bar 104 and the back plate 102, the positioning reliability between the light bar 104 and the backlight 102 may be reduced. If it further deteriorates, the light bar 104 may gradually fall off completely, and heat from the light source concentrates, making it difficult to dissipate, thereby reducing the optical efficiency and improving the overall effectiveness, reliability, and quality of the backlight module. Will deteriorate.

  Patent Document 1, Patent Document 2, Patent Document 3 and Patent Document 4 all disclose a light source fixing method in a backlight module.
