What's the difference between digital tube and LCD?

Generally speaking, digital tubes are cheaper than liquid crystal display modules.

2. Display features:

The electron gun scans the digital tube, and the light passes through the liquid crystal imaging liquid crystal display module;

The display content of digital tube is single, but the liquid crystal is rich;

The digital tube is usually 7 segments and 8 characters. Of course, there are many meters in the middle of the 16 segment, and the liquid crystal can display various contents.

Digital tube self-luminous, liquid crystal by backlight (environment);

Digital tube is the luminous effect of LED, and liquid crystal is the shadowing effect caused by molecular deflection.

3. Development trend:

The future competition of LED industry will depend on two aspects. First, technology, including the technology of improving luminous efficiency and reducing cost, and the technology of improving device power, is an extension of the existing technical route, and new technical routes may also appear. It also includes the process technology of obtaining high-quality products, as well as peripheral technologies such as lighting system design and driver chip design; The second is scale. On the one hand, because of its large scale, it can reduce costs and has strong market bargaining power. On the other hand, compound epitaxial wafers are very different from silicon wafers used in integrated circuit manufacturing, because even wafers produced on the same epitaxial wafer may have very different properties. For applications with high consistency requirements (such as LCD panel backlighting), only some epitaxial wafers meet the requirements, but for large enterprises, with a multi-level market structure, chip products that do not meet the requirements in one market can be distributed to another market, and the overall output efficiency of the company has been fully improved.

Under the situation of continuous technological innovation, falling prices and huge market potential, the use of LED display screens will be more common, not only in public life and business activities, but also in all aspects of our lives. Driven by this, the LED display industry will gain more development opportunities and maintain a good momentum of vigorous development.
