I've talked about this for a while now. Wolfspeed is screwed.
I assume this is just complaining from them after receiving CHIPS act funding.

Tianma launches group standard for rigid-flexible hybrid structure OLED display
Recently, the group standard T/CVIA 143-2024 T/DTIA 006-2024 "Technical Specifications for Rigid-Flexible Hybrid Structure OLED Displays" developed by Tianma was approved by the China Electronic Video Industry Association and the National New Display Technology Innovation Center and officially released. The release of this standard is an important milestone in the standardized development of the rigid-flexible hybrid structure OLED display industry.
The standard specifies in detail the classification, technical requirements, test methods, inspection rules, marking, labeling, accompanying documents, packaging, transportation, storage and application environment of rigid-flexible hybrid structure OLED displays, and includes core display performance requirements. As the first rigid-flexible hybrid structure OLED standard, the release of this specification fills the gap in the industry and further improves the standard system in the OLED field. The formulation and implementation of the standard provides a basis for the evaluation method of rigid-flexible hybrid structure OLED displays, which is conducive to improving product quality and promoting the healthy and rapid development of the rigid-flexible hybrid structure OLED display industry.
The rigid-flexible hybrid structure OLED display, also known as "Hybrid AMOLED technology", is a new technology that combines a glass substrate and a thin-film package. Compared with rigid OLED panels, it is thinner and lighter, and can be nearly as thin and light as a flexible OLED panel. Compared with flexible OLED panels, it has a lower cost. At the same time, it can also solve the problems of wrinkled and uneven edges, low strength and reliability when the screen becomes larger. It can make the product have lower power consumption, longer life and better picture quality, and can be widely used in display fields such as wearables, mobile phones, cars, and laptops.

Abstract
The maglev technology has been recently used for advanced semiconductor equipment. The stringent accuracy requirement of the semiconductor manufacturing processes has posed new challenges about modeling and control of maglev systems (MLSs). This paper presents a new sliding mode control (SMC) scheme, named as SMCLFF, to tackle the impacts of inherent non-linearities caused by leakage and fringing fluxes (LFF), and external disturbances caused by the gap measurement mismatch (GMM) and non-orthogonal force (NOF) on the control of the MLS. A dynamic separation model (DSM) is designed to model the LFF effects in both the current–flux density (I–B) relationship and the flux density–force (B–F) relationship. The system is linearized by the DSM firstly, and the residual LFF effects and the external disturbances are suppressed by adaptive RBF neural networks (NNs) in SMCLFF respectively. The stability of the closed-loop control system was analyzed. Experiments were performed on a one-dimensional MLS plant. Results show that the DSM can effectively compensate for the LFF effects, and SMCLFF can enable the MLS to obtain high performance in a closed-loop control system.
