Vehicle‐mounted displays are subject to some unique use‐cases and integration constraints that must be thoroughly considered during development to make the project successful, and the customer and end‐user pleased. This paper will touch upon some of the areas of automotive display engineering that deserves special attention. The automotive industry follows the development of MicroLED with excitement, as it holds promise of increased robustness and brightness, as well as new display types. This paper will examine some of the features that make MicroLED unique, the current state of research and its possible impact on the automotive industry. [ABSTRACT FROM AUTHOR]

In this comprehensive study, we rigorously evaluated the applicability of amorphous indium gallium zinc oxide (a‐IGZO) thin films synthesized using atomic layer deposition (ALD) technology in the field of large‐area organic light‐emitting diode (OLED) TVs. The key term to display production is the distribution of device characteristics, and maintaining uniformity can improve productivity yield and product quality. The purpose of this paper is to present guidelines for early application in industry through the process variable exploration results of ALD deposition equipment. The process parameters studied are process pressure and oxygen partial pressure (PO2). We have secured a method to secure device characteristics suitable for display technology through the correlation between a‐IGZO thin film characteristics and device characteristics through corresponding parameters. Our empirical data strongly demonstrate that the threshold voltage (Vth) stabilizes near 0.0 V and consistently achieves device mobility exceeding 15 cm2/Vs. In particular, this study shows that the variability of the Vth characteristic, which is limited to a narrow range of less than ±0.1V, is greatly reduced, and the mobility dispersion is also greatly reduced to less than ±1cm2/Vs. A deeper analytical exploration revealed that the pivotal factors affecting device performance are closely related to oxygen vacancies (Vo) and their dynamic interactions with oxygen molecules. These results will improve the uniformity of device characteristics, and it is believed that the introduction of ALD technology into future display technology will demonstrate improvements in the performance and quality of display products.

To provide clear see‐through image quality is one of the most important performances of a transparent display, because of its see‐through capability. Purity is one of the quantitative measure can evaluate the see‐through image quality in terms of perceived blurriness. In this paper, the characteristics of purity are investigated. Experimental results indicate that the purity values have highly correlated with perceptual blurriness of see‐through images. Furthermore, the perceptual limit of purity value is also derived.

This paper reported on the development of a Mura‐free and high precise printing to realize high resolution QLED and OLED display panels with a G8.5 glass substrate. To realize Mura‐ free printing we developed the single‐path print line head and the new pixel volume adjustment system with a pixel volume variation of ±0.8%. And also, to realize high precise printing we developed the G8.5 table system that compensated for the drop position by changing the ejecting time of each nozzle. And verified a drop position accuracy of ±2.1μm. By combining these technologies, we achieved Mura‐free 220ppi printing on the G8.5 table. [ABSTRACT FROM AUTHOR]

As a self‐emissive technology, microLED displays retain all benefits of OLEDs and should be able to improve on many aspects, but will it be enough to guaranty success? In February 2024, leading proponent Apple canceled its microLED smartwatch project. More generally, as microLED keeps getting delayed and OLED keeps improving, the value proposition of microLED is shrinking. This paper looks at how the technology could deliver stronger differentiation. [ABSTRACT FROM AUTHOR]

Due to their very high resolution and high level of technological maturity, OLED microdisplays are an ideal image generator for VR, AR and MR applications in near‐to‐eye optics. However, due to the silicon‐based backplane, these microdisplays have always been non‐transparent, requiring a complex optical system for integration into an optic. This has a significant impact on the weight, size and overall optical efficiency of the system. In this paper, a novel technology for the realization of semi‐transparent OLED‐on‐silicon microdisplays is presented, which enables completely new optical concepts for near‐to‐eye optics.
