Introduction to New Standards
On October 16, two group standards led by Tianma—T/CVIA 145—2024 “Visual Testing Methods for Micro LED Display Quality” and T/CVIA 146—2024 “General Specifications for Light-emitting Chips for Micro LED Displays”—were officially released under the organization of the China Electronic Video Industry Association’s Mini/Micro LED Display Industry Branch (CMMA).
T/CVIA 145—2024 Overview
The T/CVIA 145—2024 standard outlines the testing conditions and methods for visually assessing the quality of Micro LED displays as perceived by the human eye. It is applicable to Micro LED displays used in smartphones, smartwatches, automotive applications, and televisions, covering viewing distances from 10 centimeters to 10 meters, facilitating the detection of visually discernible defects.
T/CVIA 146—2024 Overview
The T/CVIA 146—2024 standard specifies the performance requirements, testing methods, and inspection rules for Micro LED light-emitting chips used in displays. The release of these two standards fills a significant gap in the industry, enhancing the standard system for Micro LED technology. They are instrumental in regulating industry competition, improving product quality, and promoting high-quality development, thereby fostering a healthy industry cycle and providing robust support for the advancement of Micro LED technology.
Tianma’s Leadership and Innovation
As a leading company in the display industry, Tianma is committed to a market- and customer-driven approach, prioritizing innovation and continuously increasing R&D investments. The company has strengthened its forward-looking technology layout and product development. Tianma ventured into the Micro LED technology field as early as 2017 and has consistently made breakthroughs in technology, earning numerous domestic and international awards. In 2021, Tianma co-founded the first Micro LED ecosystem alliance with over 100 upstream and downstream manufacturers. In 2022, the company invested in the construction of a full-process Micro LED production line, transitioning from mass transfer to display modules, and held a lighting ceremony on June 26, 2024, marking the start of trial production. This initiative established a leading platform for Micro LED technological innovation, product application development, and an open platform for scientific research achievement conversion in the entire industry.
Commitment to Standardization
In addition to advancing technology, Tianma actively leads the formulation and revision of standards. Last year, it spearheaded the development of T/CVIA 126—2023 “Optical Performance Technical Specifications for Micro LED Displays—Automotive Conventional” and T/CVIA 127—2023 “Optical Performance Technical Specifications for Micro LED Displays—Automotive Transparent.” Tianma will continue to promote standardization efforts to drive industry development.
