The devices have been fabricated on InGaN blue and green wafers, emitting light at the wavelengths of 468 and 508 nm, respectively. A simple circuit, which enables the display of an arrow pattern with ~60% of the pixels turned on, was used for device testing. At an injection current of 60 mA, the devices deliver 3.3 (blue) and 2.4 mW (green) of output power, corresponding to a luminance of more than 30 000 Cd\/m<sup>2<\/sup>. These high-brightness and highly versatile devices are certainly an attractive form of emissive micro-display.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DOI:<a href=\"https:\/\/doi.org\/10.1109\/LED.2004.826541\" data-type=\"URL\" data-id=\"https:\/\/doi.org\/10.1109\/LED.2004.826541\"> 10.1109\/LED.2004.826541<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8211; HW Choi, C Liu, E Gu, G McConnell, JM Girkin, IM Watson, and MD Dawson IEEE Electron Device Letters, vol. 25, 5, pp. 277-279&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[5,4,8],"class_list":["post-104","post","type-post","status-publish","format-standard","hentry","category-publications","tag-display","tag-microled","tag-monolithic"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/posts\/104","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/comments?post=104"}],"version-history":[{"count":3,"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/posts\/104\/revisions"}],"predecessor-version":[{"id":163,"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/posts\/104\/revisions\/163"}],"wp:attachment":[{"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/media?parent=104"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/categories?post=104"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.eee.hku.hk\/microLED\/wp-json\/wp\/v2\/tags?post=104"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
