Flat panel display technology standards and international synchronization

Ministry of information industry of flat panel display technology standard working group of the Secretary General

There are many types of flat panel display, usually by the media and the working principle of display, mainly in the following categories: liquid crystal display (LCD), plasma display (PDP), organic light emitting diode display (OLED), field emission display (FED), vacuum fluorescent display (VFD), electroluminescent display (ELD), a semiconductor light emitting diode display (LED) etc.. Flat panel display industry chain is usually composed of each link, the middle and lower reaches of the upstream raw materials, components, including the driver IC supplier; middle panels and modules including downstream suppliers; including the application of product assembly factory.

Flat panel display production process involves many fields of optical, mechanical and electrical, chemical, material, so the required technical level is extremely wide, few manufacturers can range from single materials to all areas of the finished product, so the industry chain downstream in different areas of clear division of labor. Downstream application of a wide range of products, from all kinds of household appliances to the consumer, information, communications and industrial products, as long as it is necessary to display equipment and devices, you can use the flat panel display products. However, the flat panel display which can be used as high definition TV only has several kinds of LCD, plasma, organic light-emitting diodes, field emission display and so on. In the current flat panel display industry chain, the LCD industry chain is the most complete:

Flat panel display technology industry standards

The standardization organizations related to the flat panel display industry in China are: the Ministry of information industry flat panel display technical standards working group, the National Technical Committee for standardization of audio, video and multimedia systems and equipment. The two standards organizations have different emphases: the audio, video and multimedia systems and Equipment Standardization Technical Committee is mainly involved in one of the flat panel display industry chain downstream products -- Application of flat-panel TV; the Ministry of information industry of flat panel display technology standard working group is mainly involved in the flat-panel display industry chain in the middle panels and modules, at the same time taking into account the coordination between upper and lower reaches.

The audio, video and multimedia systems and Equipment Standardization Technical Committee is engaged in audio, video and multimedia professional standardization, the international organization for standardization is: IEC/TC100 audio, video and multimedia systems and equipment technology committee. In 2006 the Ministry of Information Industry released 25 digital television standard, is the working group by the technical committee of the digital television receiving equipment functions and performance standards shall be formulated, which involves digital flat-panel TV standards: SJ/T 11339-2006 "digital TV plasma display general specification"; SJ/T 11343-2006 "general digital television LCD display specification" SJ/T 11348-2006; "digital flat-panel TV measurement method". These standards play a significant role in regulating the market of flat panel digital tv.

The Ministry of information industry of flat panel display technology standard working group was established in June 2003, currently has four professional groups: liquid crystal display technology (LCD) group, plasma display technology (PDP) group, organic light emitting diode display technology (OLED) and semiconductor light emitting diode display technology group (LED screen) group. There are 40 member units, involving the flat panel display technology industry chain, the upstream, downstream production, learning, research parties.

Standard setting. The completion of the 8 national standards and industry standards work: the national standard "plasma display devices - Part 2-1: Test methods for optical parameters of national standard"; "plasma display devices - Part 2-2: Test methods for optical parameters of" national standard "; plasma display devices part first: Terminology and symbols of national standards"; "liquid crystal and solid state display devices - Part 2-2: Blank detail specification" color matrix liquid crystal display module; the national standard "liquid crystal and solid-state display devices - Part 4-1: colour matrix liquid crystal display module essential ratings and characteristics of industry standard"; "plasma display devices - Part 3-1: mechanical interface" industry standard "plasma display; the fourth part:" device durability test environment and machinery industry standard "; LED display test Law. The development of these standards, the basic standards of the PDP system and the basic standards of LCD and LCD products in the upper standard.

Participate in international standardization work. IEC/TC110 flat panel display technology committee after 3 years of development, there are currently working group: WG2 - liquid crystal display devices, WG4 - plasma display devices, WG5 - organic light-emitting diode display devices. The main contents: the development of the field of flat panel display standards, such as LCD, PDP, OLED and other devices display text symbols, terminology, ratings and characteristics, test methods, general specification and the relevant environmental, mechanical and durability test method etc.. Now published a total of 14 standards, including LCD10, PDP4 items; ongoing standards of a total of 15 items, including LCD4, PDP4, OLED5, as well as a new proposal for the 2.

LCD aspects of the most relevant standards published, the main: General specification, sub standard and blank detail specification, the basic rating and characteristics, environmental / mechanical / durability test methods, etc.. There are a number of standards published in PDP, including: terms and definitions, optical and optoelectronic parameters testing methods, mechanical interface rules, etc.. OLED industry started late, the relevant standards are still in the drafting stage.

IEC published standards we have already developed or are being developed, CD
