Title: MANUFACTURING METHOD FOR LED LIGHT BAR, LED LIGHT BAR AND BACKLIGHT MODULE
Abstract:
A manufacturing method for an LED light bar (10) comprises the steps of: 1. providing light-emitting chips (142) of different sizes; 2. measuring the light-emitting intensity of the light-emitting chips (142); 3. selecting light-emitting chips (142) of which the light-emitting intensity difference is smaller than 5%; 4. respectively packaging the selected light-emitting chips (142) into LED lamps (14), the LED lamps (14) all having the same package size; and 5. installing the LED lamps (14) on and electrically connecting same to a PCB (12) to form an LED light bar (10). Also disclosed are an LED light bar (10) and a backlight module. Using the light-emitting chips (142) of different sizes, the manufacturing method for an LED light bar (10) increases the wafer utilization rate, and effectively reduces the cost.
