Industry Breakthrough! Our Company Has Made Significant Progress in Vertical Stacking of Micro-LED Pixels.
2023-09-12 10:17
Our company has recently successfully launched the VSP (vertically stacked pixels) process flow, realizing the single-chip integration of AlGaInP and GaN material systems. This technology adopts the WLVSP (wafer level vertically stacked pixels) technology solution. After completing the preparation of AlGaInP red micro-display chips, it continues to stack InGaN wafer materials, which can achieve vertical stacking of pixels on a single driving backplane.
This is another major milestone in VSP technology for our company after lighting up 0.39" and the world's smallest 0.12" RGB micro-display chips, fully verifying the feasibility of INNOVISION's VSP technology solution. It is a step further towards single-chip full-color Micro-LED display chips after completing the full waveband layout..
RGB Micro-display Chips
It is worth noting that VSP technology has the advantage of compatibility with large-size wafers. Earlier this year, our company completed the R&D and tape-out of 8-inch silicon-based Micro-LED micro-display chips, verifying the feasibility of large-scale wafer production using VSP technology and completing relevant technical reserves. According to calculations, this technical route can significantly reduce the cost issues that Micro LED urgently needs to address.
8" and 4" Micro-LED Display Wafers
Our company uses the VSP (Vertically Stacked Pixels) technology to break through the physical limitations of difficult pixel miniaturization in the micro display field, and create high-performance micro display chips. With the support of integrated circuit technology and large-sized compound semiconductors, our company adheres to the product concept of "integration of chip and screen" and "combination of display with lighting", achieving coverage of multiple application scenarios from XR to car lights, and contributing to the development of the Micro-LED display chip industry.
