“…Recently, there were reports that LTPS-TFT backplane could be applied for the AM driving micro-LED displays [10,11]. In order to solve color shift of LEDs by the LTPS-TFT backplane, pulse-width-modulation (PWM) driving must be designed by using a plurality of TFTs in a pixel.…”

12.1‐inch 169‐ppi full‐color micro‐LED display using LTPS‐TFT backplane has been successfully developed. Blue micro‐LED, whose size is less than 30 mm, was applied with red and green conversion materials to produce full‐color images. Contrast ratio of >1,000,000: 1 with brightness of 700 nits was realized by the full‐color micro‐LED display for high‐dynamic‐range display applications.

“…Here, the authors proposed a flexible micro‐LED array for in vivo optical recording of intrinsic signal (ORIS). The high spectral selectivity, brightness, and reliability of micro‐LEDs is making them an outstanding candidate for future high‐resolution active‐matrix displays, and this report successfully extended their applicability to the biomedical area. Especially, the direct spatiotemporal monitoring of brain requires individually addressable small pixels, and this can be well satisfied with micro‐LED devices.…”

Ever‐increasing demand for a healthy and sustainable life has been a traditional motivation behind state‐of‐the‐art medicines and precision diagnosis tools. Nowadays, the ultra‐connectivity and data‐centric initiatives that underpin the future Internet of Things is seen as another major driver of electronically enriched, highly customizable healthcare platforms. Especially, the information display technology, which already enjoys its position as an all‐round player in consumer electronics is poised to broaden its territory by envisioning a range of bio‐related features. In this review, the rising opportunities for next‐generation display‐based biotechnology and healthcare systems are critically assessed in light of recent literature. Clearly, smart combination of new materials, devices, and integration strategies has given rise to highly promising prototypes, and this article aims at highlighting some of these examples. Despite such progress, it is still unclear whether the resultant technologies will make a measurable impact in the near future, given both their own scientific limits and the lack of proper business model. In this regard, the final part of this contribution is dedicated to emergent challenges as well as development solutions that this potentially disruptive innovation may need to consider.

“…Recently, Kim et al developed remarkably bright active-matrix μLEDs using the LTPS TFT backplane. 17 A solder bump material was employed for bonding the LTPS backplane to the μLED array. However, this process may cause pressure damage and stress within the μLEDs, which results in a fracture.…”
