In order to make 3C electronic products less limited by strong light and lighter, thinner, and more realistic, display panel manufacturers are currently actively developing the next generation display technology Micro LED (Micro Light Emitting Diode) to meet this demand. Compared with traditional LEDs, Micro LED can achieve higher brightness, lower power consumption, and wider color gamut to meet future smart display applications, such as the watches, AR glasses, mobile phones, and computers we wear. However, There are various technical challenges in the mass production and measurement verification of micro LED processes with extremely small dimensions, which are challenges that the industry is trying to solve.
The Taiwan Institute of Industry and Technology has successfully developed a high-precision two in one "Micro LED Display Module Quick Detection Technology" that focuses on color correction and optical detection, which can simultaneously detect colors and light source angles.
Lin Zengyao, Executive Director of the Measurement Technology Development Center of the Taiwan Institute of Industry and Technology, stated that Micro LED technology is too forward-looking and does not have a certain specification in the market. It must be customized to meet the unique needs of brand factories, and therefore there is no precedent in testing or repairing. The research and development team of the Taiwan Institute of Industry and Technology first starts with color uniformity testing, which the industry urgently needs to solve.
Due to the small size of Micro LEDs, the camera pixels of traditional display measurement equipment lenses cannot meet the detection requirements. The research and development team of the Taiwan Institute of Industry and Technology utilized the "repeated exposure color correction technology" to achieve color balance on Micro LED panels through repeated exposure, and analyzed color uniformity through optical correction technology to achieve accurate measurement purposes.
Furthermore, due to the inherent characteristics of the material, Micro LEDs have a wide color gamut range and self luminescent properties, thereby achieving high contrast and wide viewing angle. Traditional measurement requires rotating instruments to collect light sources from different angles for testing. The research and development team of the Taiwan Institute of Industry and Technology has installed multi angle receiving lenses on existing optical measurement machines, assembling light sources from different angles at once, and utilizing innovative software analysis technology, By presenting the light source on the same interface at the same time, it achieves fixed point measurement, significantly reducing detection time by 50%, and successfully breaking through the traditional 100 degree light source angle detection, expanding to about 120 degrees.
Micro LED has the characteristics of miniature, low power consumption and high brightness, which can integrate sensors into the same module. For the interior of future cars, it can provide interactive smart cockpit features to drive the intelligent experience of high immersion.
The Taiwan Institute of Industry and Technology has successfully developed a high-precision two in one "Micro LED Display Module Quick Detection Technology" with the support of the technical department. It provides customers with customized testing of various new products through a two-stop rapid analysis of the color uniformity and angle optical rotation characteristics of micro light sources, and improves the measurement efficiency by 50% compared to traditional equipment. We hope to assist the industry in breaking through mass production difficulties through advanced technical testing, Entering the next generation to display a new world.
