ULTRA-DENSE LED PROJECTOR |
| abstract |
The invention relates to a monolithic projector / display comprising a single chip having a network of mechanically isolated LED columns. Each column has a height greater than its width, and a pitch between columns is less than the column heights. The chip has an LED display portion bonded to a silicon substrate addressing portion, including a pixelized metal contact. The resolution of the display is preferably substantially the same as the resolution of the human retina when projected onto the human retina so that it is impossible to distinguish the image projected on the retina as not belonging to the human retina. real world. The display may be encapsulated in a contact lens with focusing optics incorporated in the contact lens. In order to make electrical contact with the N type semiconductor layer, the columns are surrounded by a reflective cathode metal mesh so that the cathode current is coupled through the vertical sides of the type layer. N. The wire mesh mechanically connects the insulated LED columns and optically isolates each column of LEDs. Active layers can emit blue light, and wavelength conversion layers can be used to generate red and green light. |
