The differences between LED digital tubes and LCD displays are mainly reflected in the following three aspects:

1、 Price difference: Generally speaking, the price of digital tubes is lower than that of LCD display modules.

2、 Display function:

The digital tube is scanned with an electron gun to form an image, while the liquid crystal display module uses light to pass through the liquid crystal to form an image;

Digital display screens have a single content, while LCD screens are more diverse;

A digital tube is usually a seven segment eight character display, with an additional 16 segments and a one meter font in the middle. The LCD can display various contents;

Digital tubes are self luminous, while liquid crystals rely on backlighting (environment);

A digital tube is the effect of a light-emitting diode, while a liquid crystal is the shadow effect caused by molecular deflection.

3、 Development trend:

The future competition in the LED industry will depend on two aspects: one is technology, which improves luminous efficiency, reduces costs, and increases device power; The second is scale, which can expand the existing technological route; The third is the process technology to obtain high-quality products; The fourth is peripheral technology, such as lighting system design and driver chip design; Number five is scale, partly because it can reduce costs and has strong market bargaining power; The sixth is compound epitaxial wafers, which are significantly different from silicon wafers used in integrated circuit manufacturing. Even chips produced on the same epitaxial wafer can have significant differences in performance. For applications that require high consistency, such as LCD panel backlighting, only a portion of a single epitaxial wafer meets the requirements. However, for large enterprises, a single epitaxial wafer has a multi-level market structure and can transfer chip products that do not meet certain market requirements to another market, greatly increasing the overall production of the enterprise.

With the continuous innovation of technology, the decline in prices, and the huge potential market, the application of LED displays will become more widespread, not only in public and commercial settings, but also in various aspects of our lives. And under this driving force, the LED display industry will gain more development opportunities and maintain a good development momentum.
