Claim 8:
9. A computer-readable storage medium, wherein the computer-readable storage medium stores a television backlight adjusting program, and wherein a backlight comprises M rows and N columns of LED lamps, in each row of the LED lamps, a distance between two adjacent LED lamps is an arithmetic progression or a geometric progression from a center to an edge, and when the television backlight adjusting program is executed by a processor, to implement a television backlight dimming method comprising following steps:
acquiring a minimum horizontal distance between the LED lamps in a reference region and the LED lamps in non-reference regions; and
adjusting brightness of each of the LED lamps in the non-reference regions according to brightness of the LED lamps in the reference region, the minimum horizontal distance, and a preset distance rule,
wherein each of M and N is positive integer,
wherein the preset distance rule comprises one of a first distance rule corresponding to the arithmetic progression and a second distance rule corresponding to the geometric progression, and
wherein the step of adjusting the brightness of each of the LED lamps in the non-reference regions according to the brightness of the LED lamps in the reference region, the minimum horizontal distance and the preset distance rule comprises one of:
determining each of first horizontal LED lamps in a same row among the LED lamps in each of the non-reference regions according to the LED lamps in the reference region, adjusting brightness of each of the first horizontal LED lamps according to the brightness of the LED lamps in the reference region, the minimum horizontal distance, a preset horizontal common difference, and the first distance rule, and adjusting the brightness of each of the LED lamps in the non-reference regions according to the brightness of each of the first horizontal LED lamps; and
determining each of second horizontal LED lamps in a same row among the LED lamps in each of non-reference regions according to the LED lamps in the reference region, adjusting brightness of each of the second horizontal LED lamps according to the brightness of the LED lamps in the reference region, the minimum horizontal distance, a preset horizontal geometric difference value, and the second distance rule, and adjusting the brightness of each of the LED lamps in the non-reference regions according to the brightness of each of the second horizontal LED lamps.
