Abstract:
1. A method for mounting a light bar that enhances central point brightness of a backlight module, comprising the following steps: (1) providing a PCB and a plurality of LED lamps of various specifications, wherein the LED lamps of various specifications are of different luminous intensities, difference of luminous intensity among the plurality of LED lamps being less than 20%; (2) positioning the plurality of LED lamps on the PCB in a spaced manner and electrically connected to the PCB, wherein LED lamps having high luminous intensities are positioned at locations close to a central location of the PCB; (3) providing a backlight module main body, wherein the backlight module main body is addible with a backlight source to form a backlight module; (4) positioning the PCB on which the LED lamps are positioned on the backlight module main body to serve as a backlight source thereby forming the backlight module; (5) measuring central point brightness and illumination homogeneity of the backlight module; (6) adjusting the spacing distance between the LED lamps of the PCB according to predetermined central point brightness and illumination homogeneity so as to have the central point brightness and illumination homogeneity of the LED lamps satisfying requirements; and (7) mounting the LED lamps to the PCB so as to form an LED light bar.
