Liquid crystal display (LCD) industrial chain structure analysis

Liquid crystal display (LCD) industrial chain structure analysis

  One.Upstream industry:Raw material supply &Display materials and equipment

  Raw material supply:The manufacture of liquid crystal display requires a variety of raw materials,such as glass substrate. ITO conductive film,polarizer,color filter,liquid crystal material,driver IC,etc.The quality and performance of these raw materials directly affect the quality and performance of the Lcd screen.

  Display materials and equipment:including a variety of chemical materials,photoresist,developer, etc.,for the manufacture of liquid crystal displays,as well as a variety of equipment used in the manufacturing process,such as lithography machine,coating machine, etching machine,etc.

  Two.Midstream industry:Panel manufacturing and module assembly

  Panel manufacturing:The LCD panel is the core component of the LCD display screen,and its manufacturing process includes the front segment array process,the middle segment box process and the rear segment module process.Panel manufacturing requires highly sophisticated technology and equipment,as well as strict quality control.

  Module assembly:The LCD panel and backlight module,driver circuit and other components are assembled to form a complete LCD display.Module assembly requires a certain level of technology and automated production lines.

  Three.Downstream industry:end-product applications

  Terminal product application: LCD screen is widely used in various electronic products,such as TV,computer monitor,mobile phone, tablet computer,car display and so on,The market demand and.eplacement speed of these terminal products will directly affect the development of the LCD display industry,

  Liquid Crystal Display,the full name of liquid crystal display,is a display made of liquid crystal materials.Its working principle is to use a matrix display driven by thin film transistors to stimulate liquid crystal molecules with current,thus producing points,lines,and surfaces with LED backlight to form a display screen.Liquid crystal display is widely used in various electronic devices,such as TV,computer monitor,mobile phone,tablet computer and so on.

  The LCD industry has experienced a development process from laboratory research in the 1960s, to in-depth exploration in the 1970s, and then to commercialization in the 1980s. After entering the 21st century, with the popularity of electronic products and the rapid development of the Internet, the LCD display industry ushered in a period of rapid development. With the advancement of technology, the picture quality of LCD displays has been significantly improved, and the size is also getting larger and larger, meeting the consumer's demand for higher quality and larger screens.

  At present,the LCD industry has formed a complete industrial chain,including upstream raw material suppliers,midstream LCD panel manufacturers and downstream terminal product manufacturers.Among them,LCD panel manufacturers are the core of the industry,and their technical level and production capacity directly affect the development of the entire industrial chain.

  In terms of technological innovation,the LCD display industry continues to introduce new technologies and new products,such as the application of high refresh rate,high resolution,wide color gamut and other technologies,as well as the emergence of new products such as curved screens and folding screens,which have greatly promoted the development of the industry.
