MicroLED display is an emerging technology with high brightness, high contrast ratio, and wide color gamut. This technology can be used for all current display applications and new scenarios, such as transparent, seamless tiling, and AR glasses for metaverse. Based on our proprietary PixeLED display, PixeLED Matrix, µ‐PixeLED, and SMAR·Tech technologies, we could define the roadmap of MicroLED technology development.

The magnesium oxide is one of the promising candidate's materials that can act as solar blind photodetectors. However, the intrinsically low thermal conductivity of MgO, which is restrict the application in electric device. The magnesium oxide exhibits the poor conductivity which could improved by doing method. This paper fabricated magnesium indium oxide (MgInO) solar-blind photodetectors by doping indium oxide with magnesium oxide through co-sputtering deposition method. The photodetector comprises a bottom glass substrate, an MgInO thin film, and an interdigitated gold electrode to complete the metal-semiconductor-metal structure of the solar-blind photodetector. The experimental results indicate that the photo-to-dark-current ratio is 1.4 × 10 4 , and the responsivity is 1.47 A/W when a reverse bias voltage of 2 V is applied. Furthermore, the noise equivalent power and detectivity are 7.77×10 -11 W and 1.75×10 11 cm H 0.5 W -1 with a 2 V bias voltage, respectively.

A 4,000 PPI phase‐only NCTU PCU‐3‐01 LCoS‐SLM filled with UCF‐L1 NLC was assembled and evaluated. The resulting LCoS panel possessed 1.6 ms of linear‐full‐phase‐modulation response time under digital driving (V w = 4.5 V, V b = 0.3 V) at T = 45 °C. The 3D holographic images show that most diffracted light is transferred within 2 ms. Meanwhile, a low‐latency driver solution based on 1920 x 640 at 240 Hz (equivalent to 4000 PPI) input frame rate and 720 Hz data frame rate were presented.

Digital Electro‐optics Platform is the main concept of Jasper Display Corp. (JDC) to develop various applications. These applications are based on our X‐on‐Silicon technologies, for example, X‐on‐Silicon technologies could be used on Liquid Crystal on Silicon (LCoS), Micro Light‐Emitting Diode on Silicon (pLEDoS), Organic Light‐Emitting Diode on Silicon (OLEDoS), and Cell on Silicon (CELLoS), etc. In this paper, we provide novel concepts and real cases for near‐to‐eye applications based on phase‐only LCoS‐SLM and μLEDoS, such as holographic near‐to‐eye displays and focal surface displays.

In the past few decades, demand forecasting has become relatively difficult due to rapid changes in the global environment. This research illustrates the use of the make-to-stock (MTS) production strategy in order to explain how forecasting plays an essential role in business management. The linear mixed-effect (LME) model has been extensively developed and is widely applied in various fields. However, no study has used the LME model for business forecasting. We suggest that the LME model be used as a tool for prediction and to overcome environment complexity. The data analysis is based on real data in an international display company, where the company needs accurate demand forecasting before adopting a MTS strategy. The forecasting result from the LME model is compared to the commonly used approaches, including the regression model, autoregressive model, times series model, and exponential smoothing model, with the results revealing that prediction performance provided by the LME model is more stable than using the other methods. Furthermore, product types in the data are regarded as a random effect in the LME model, hence demands of all types can be predicted simultaneously using a single LME model. However, some approaches require splitting the data into different type categories, and then predicting the type demand by establishing a model for each type. This feature also demonstrates the practicability of the LME model in real business operations.
