Problems solved by technology

The advantage of using the anisotropic conductive layer is that the semiconductor light-emitting element and the wiring electrodes can be electrically connected only by thermocompression bonding. However, there is a problem that when the area of ​​the wiring substrate becomes large, the semiconductor light-emitting element Poor contact will occur between wiring electrodes

Abstract

The present invention includes a substrate, a wiring electrode disposed on the substrate, a plurality of semiconductor light emitting devices electrically connected to the wiring electrode, and an anisotropic conduction comprising a mixture of conductive particles and an insulating material disposed between the semiconductor light emitting devices and a light transmitting layer formed between the semiconductor light emitting devices. The anisotropic conductive layer is also formed between the wiring electrodes, and the light transmitting layer is formed on the anisotropic conductive layer formed between the wiring electrodes.

Description

technical field [0001] The present invention relates to a display device and a control method thereof, in particular to a flexible display device using a semiconductor light emitting element. Background technique [0002] In recent years, in the technical field of displays, display devices that are thin and have excellent characteristics such as flexibility have been developed. On the contrary, currently commercialized displays are mainly represented by LCD (Liguid Crystal Display: Liquid Crystal Display) and AMOLED (Active Matrix Organic Light Emitting Diodes: Active Matrix Organic Light Emitting Diodes). [0003] On the other hand, light-emitting diodes (Light Emitting Diode: LED) are well-known semiconductor light-emitting elements for converting electric current into light. In 1962, red LEDs using GaAsP (gallium arsenide phosphorous) compound semiconductors became commercialized as an opportunity. Together with GaP:N-based green LEDs, it is used as a light source for di...
