Patent number: 7309152Abstract: A light source structure of a backlight module comprises: a bar-shaped light source; and a group of complementary color light emitting diodes mounted at both ends of the bar-shaped light source. The bar-shaped light source is composed of several light emitting diodes having complementary light colors. The luminous intensity of outermost light emitting diodes of the bar-shaped light source is 30 to 70% of average luminous intensity of the other equal color light emitting diodes. The complementary color light emitting diodes have light colors complementary to that of the outermost light emitting diodes of the bar-shaped light source. The luminous intensity of the complementary color light emitting diodes is 10 to 50% of average luminous intensity of the other equal color light emitting diodes of the bar-shaped light source. Consequently, the non-uniform mixing of lights on edges of the backlight module and the producing of bright point can be avoided.Type: GrantFiled: November 23, 2005Date of Patent: December 18, 2007Assignee: Unity Opto Technology Co., Ltd.Inventor: Tai-Ho Huang
