Role of OLED Micro Displays in Next Generation VR Glasses

Virtual Reality or VR glasses are extremely popular in today’s high tech world. VR glasses are widely used in video gaming, military trainings, medical field etc. A major disadvantage concerning these glasses is that they are usually heavy and oversized. This is primarily because of the display, which is the core component in these glasses. Frequently, cheaply available displays designed for the smartphone market, are used in making these glasses. These displays have insufficient pixel density and limited resolution.

Lately, it has been found that highly efficient, comfortable in working environment and light in weight VR glasses can be produced by using large-area organic light-emitting diodes (OLED) micro-displays. These are made up of two components: a silicon chip to control the pixels, and an OLED which consists of several organic layers. The micro-displays are self illuminating, energy efficient and produce very high contrast ratios. The researchers at the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP in Dresden have collaborated with partners from industry to develop the advanced OLED micro-displays. These shall provide extraordinary picture quality and high resolution of about 1920 x 1200 pixels (WUXGA). All this shall contribute in the production of the new generation VR glasses.

Some of the challenges faced by the researchers, regarding the use of micro-displays in making VR glasses, include: high levels of luminance and efficiency; high yield for large (chip) area; curved surfaces for more compact optics etc.
