VueReal of Waterloo, Ontario Canada, announced that its Continuous PixelationTM technology has led to the development of a 4K micro-LED array display. The emissive display prototype boasts the record highest pixel-per-inch 6000 ppi. VueReal says that its Continuous PixelationTM technology offers unique features that can enable true super-high-ppi displays of greater than 4000 ppi at a very high yield and an affordable price.VueReal VueReal microLED display of tiger–only a few mms wide
According to VueReal, the Continuous Pixelation™ technology uses a very simple micro-LED structure with minimal processing steps. The company contends that this technology surpasses the performance of DLP displays with its combination of high contrast, low power consumption, much more affordable price, and smaller footprint of 4K resolution in a few millimeters. Furthermore, the microLED display does not require a single light engine which liquid crystal on silicon (LCOS) and digital light processing (DLP) displays require.
So far, the company has only unveiled a dual color version and has yet to show how it would look with a full color range.
“At VueReal, we have always been interested in simple approaches to develop affordable display products. This is more crucial as we are dealing with millions of micrometer-size LEDs in a few-millimeter display. Any complexity in developing LEDs and transferring LEDs can result in catastrophic yield loss,” said Dr. Fathi, VP of Technology at VueReal. He continued, “This technology enables us to develop sub-micrometer pixel pitch for more compact displays. In addition to consumer application, with such a high resolution, these displays can be used in maskless photolithography offering immense flexibility in fabrication.”
Could Also Serve As High-Bit-Rate Communication Channel
Yaser, VP of Circuit and System noted that another potential application for the technology when combined with the company’s circuit design techniques, is serving as an extremely compact, high-bit-rate communication channel for inter- and intra-chip communication in electronic devices and data centers.
“This technology can miniaturize the augmented reality (AR) devices such as head mounted displays (HMD) and heads up displays (HUD). This is essential for HMD devices, as they should be comfortable, fashionable and small to benefit from mass adoption. Due to significant demand in such display products from our partners, we plan to produce displays based on this technology in 2018,” said Dr. Chaji, CEO of VueReal. He added, “These displays offer high reliability and low power consumption at higher brightness (10,000s nits) required to compete with ambient conditions for AR applications.”
