What Is Display industry
Leave a message
The display industry covers from traditional liquid crystal display technology (LCD) to modern LED display technology, involving multiple aspects and areas of knowledge. Here are some key industry learnings:
Technology development history :
The development of display technology has experienced from the simple and intuitive display in ancient times, such as fire and light, to the modern display technology combining light and electricity. Modern display technology pursues clear, accurate, real-time, intuitive, convenient, energy-saving, carrying large amount of information, color and three-dimensional goals.
Liquid Crystal Display (LCD) :
Liquid crystal display (LCD) is an important part of modern display technology, and occupies an important position in the global display market with its advantages of low voltage and micro power consumption. China has a significant advantage in the LCD field, with a global display market share of 42.5% in 2022.
LED display technology :
LED display is divided into asynchronous screen and synchronous screen, asynchronous screen can be connected with the computer through the serial line to display text changes, and then you can take off the computer work. The synchronous screen requires an online computer to work, and displays the image text on the computer on the LED large screen.
The pixel of the LED display is its smallest imaging unit, and the display module composed of several display pixels is the basic constituent unit of the LED display. Indoor and outdoor screens are different in structure and application, the indoor screen is usually composed of 64x32 or 64x16 display modules, while the outdoor screen uses a single lamp bead or composed of 1-3 light beads of the same or different colors.
gamut and depth :
For a display, color gamut and color depth are important indicators to evaluate its performance. The ideal gamut coverage should be at least 98% for sRGB and 90% for DCI-P3 gamut. It is important to note that more than 100% of color gamut labeling is usually volume rather than coverage, and the true color gamut coverage parameter is critical. In addition, NTSC color gamut is mainly applicable to the TV industry, for the display, more attention should be paid to sRGB color gamut coverage.
Industry standards and specifications :
Industry standards are essential to ensure product quality and performance. For example, when choosing a display, avoid products with a labeled color gamut of more than 100% but insufficient actual color gamut coverage, which is often considered "industrial waste." Similarly, the evaluation of the LED display also includes many aspects of its box, professional terminology, site investigation content and other considerations.
In summary, the development of the display industry is not only reflected in the continuous progress of technology, but also includes the continuous optimization of industry standards and product quality control. With the rapid development of industries such as "artificial intelligence", "5G technology" and "Internet of Things", display technology will continue to evolve to meet the diversified needs of the market and consumers
