Problems solved by technology

As the size of the light-emitting unit decreases or the number of light-emitting units increases, the difficulty of making the reflective sheet increases, the structural strength of the reflective sheet decreases, and the difficulty of assembling the reflective sheet and the light-emitting unit (such as difficulty in alignment) increases, all of which lead to the production of light-emitting devices. difficulty

Abstract

The invention provides a manufacturing method of a light emitting device. The manufacturing method comprises the following steps: providing a driving substrate; disposing a plurality of light emittingunits on the driving substrate; forming a reflective layer on the driving substrate, wherein forming the reflective layer on the driving substrate includes coating the reflective layer on the drivingsubstrate.

Description

technical field [0001] The disclosure relates to an electronic device and a manufacturing method thereof, in particular to a light emitting device and a manufacturing method thereof. Background technique [0002] Traditional light emitting devices use reflective sheets to improve light utilization efficiency, or use reflective sheets to reflect light to illuminate areas where no light emitting units (such as light emitting diodes) are provided. Taking the direct type light-emitting device as an example, openings should be formed in the reflective sheet according to the position, size, or quantity of the light-emitting units, so as to prevent the reflective sheet from covering the light emitting device on the drive substrate after being attached to the drive substrate. unit. As the size of the light-emitting unit decreases or the number of light-emitting units increases, the difficulty of making the reflective sheet increases, the structural strength of the reflective sheet ...
