The new standard GB 21520-2023 "Display Energy Efficiency Limits and Energy Efficiency Ratings" was formally implemented on June 1, 2024. The energy efficiency requirements for organic light-emitting diode (OLED) monitors and light-emitting diode (LED) integrated display terminals have been added, which has become the latest national standard basis for energy-saving certification of LED all-in-one machines. The release and implementation of the new standard will strongly promote technological progress and energy efficiency improvement in the display industry, and promote energy conservation, emission reduction and sustainable development.
The new standard specifies the standard test status of the led all-in-one machine and the test methods related to energy efficiency. For high-performance led all-in-one machines, the new standard covers horizontal viewing angle, contrast ratio, pixel spacing, color gamutThere are five aspects of rate and refresh rate to divide high-performance products. The high-performance led all-in-one machine must meet at least three conditions, and the energy efficiency must be at least 2.7 cd/W to be certified as the energy efficiency of the high-performance led all-in-one machine.
Lehmann intelligent all-in-one computer uses a number of independent patented core technologies, with display, audio, multi-device screen transmission, Android and Windows dual-system architecture, touch writing applications, a large number of self-developed function programs and apps, etc. All in one intelligent functions, can create a "full immersion, strong interaction, high real-time" meeting and teaching experience for users.
Lehman Optoelectronics actively responds to the national dual-carbon strategic goals and continuously improves the energy efficiency level and market competitiveness of its products through technological research and development and product innovation. This product has successfully obtained the highest level of energy efficiency certification, proving that the technical advantages of the LED all-in-one machine developed and designed by Lehman Optoelectronics using its own core key technology cob ultra-high-definition integrated packaging panel in terms of performance, energy saving, safety and efficiency have been recognized by the industry, which is in line with the realization of the national dual-carbon strategic goals and the development needs of new quality productivity.
