Embodiment Construction

[0052] The invention provides a backlight system, which adopts a plurality of miniature light emitting diodes (LEDs) as light sources to generate a plane light source. The backlight system is usually used as a backlight of a display device. The display device can be any kind of display device that requires the backlight to provide light required for display. In the following description, a liquid crystal display device will be used as an example for illustration. The backlight system includes a backlight module and a backlight driving unit for driving the backlight module to emit light. The backlight module includes a light-emitting source array, and the light-emitting source array includes a plurality of micro-LEDs arranged in the same layer, and the distribution density of the plurality of micro-LEDs on a unit area is not uniform. That is to say, the backlight module defines a plurality of equal-area-divided light-emitting areas, and micro-LEDs are randomly distributed in t...

Abstract

A backlight system includes a backlight module. The backlight module includes a first substrate and an array of light emitting sources arranged on the first substrate. The light emitting source array includes a plurality of micro LEDs arranged in the same layer. The backlight module defines a plurality of equal-area light-emitting areas. The luminous brightness of each luminous area is the same. The number of micro-LEDs corresponding to each light-emitting area is randomly set. Micro LEDs include forward micro LEDs and reverse micro LEDs. The invention also provides a manufacturing method of the backlight system.

Description

technical field [0001] The invention relates to a backlight system and a manufacturing method thereof. Background technique [0002] A micro light emitting diode (micro LED) used as a display device of a backlight module has the advantage of low power consumption. However, due to the small size of the micro LED, micro-transfer printing is usually used to package it with other components during the preparation process. In order to ensure the stability of the forward direction and uniformity of the light source, the micro LED needs to be placed in alignment during the manufacturing process, and the manufacturing process is relatively complicated. Contents of the invention [0003] In view of this, it is necessary to provide a backlight system that can simplify the manufacturing process. [0004] It is also necessary to provide a method for manufacturing a backlight system that can simplify the manufacturing process. [0005] A backlight system includes a backlight module....
