Display device using semiconductor light emitting device and method for manufacturing the same

Abstract

A display device include a substrate including a wiring electrode; an adhesive layer disposed on the substrate; a plurality of semiconductor light emitting devices adhered to the adhesive layer, and electrically connected to the wiring electrode; and a phosphor layer disposed to cover the plurality of semiconductor light emitting devices. Further, the phosphor layer includes a plurality of phosphor portions for converting a wavelength of light, and a plurality of partition wall portions formed between the plurality of phosphor portions. The plurality of partition wall portions are sequentially disposed between the phosphor portions along a first direction and a second direction crossing each other, respectively, and at least one of the sequentially disposed partition wall portions overlaps with at least one of the plurality of semiconductor light emitting devices.

Description

technical field [0001] The present disclosure relates to a display device and a manufacturing method thereof, and more particularly, to a flexible display device using a semiconductor light emitting device. Background technique [0002] In recent years, display devices having excellent characteristics such as thinness, flexibility, etc. have been developed in the field of display technology. In contrast, representatives of the main displays commercialized today are liquid crystal displays (LCDs) and active matrix organic light emitting diodes (AMOLEDs). However, liquid crystal displays have problems such as slow response time and difficulty in achieving flexibility, while AMOLEDs have disadvantages such as short lifespan, low yield, and low flexibility. [0003] In addition, light-emitting diodes (LEDs) convert electric current into light, and have been used as light sources for displaying images in electronic equipment including information communication equipment since re...

Problems solved by technology

In this case, a partition wall structure for preventing color mixing can be provided on the phosphor layer, but research on this is insufficient

In particular, when realizing a high-definition display using a semiconductor light emitting device, the size of the semiconductor light emitting device should be reduced, but there is a limit

To solve this problem, a pentile-type display driving scheme can be used for displays using semiconductor light-emitting devices, but research on its related partition wall structure has not yet been carried out
