Abstract
In order to satisfy the special demand of AR products for ultra‐high luminescence and high resolution full‐color silicon‐based OLED micro displays, a silicon‐based OLED micro display with resolution of more than 4000 ppi (0.36 inch with 1280×720) and a luminescence of more than 5000 nit is investigated. First, the design scheme of high‐resolution silicon‐based OLED driver is introduced. Based on the scheme of strong microcavity effect OLED device, the structure of red, green and blue monochrome luminescence enhancement is verified, and the current efficiency reaches 60 cd A‐1, 95 cd A‐1 and 6 cd A‐1, respectively. Finally, the development of HD036 chip is finished, and the high luminescence full‐color silicon‐based OLED micro display device with ppi more than 4000, luminescence more than 5000 nit, and color gamut more than 85% is achieved. The effect of virtual reality overlay display is achieved by the verification of AR machine.
