As an important tool for information output and interaction, the screen is constantly updated and upgraded. There are two main types of common screens: dot matrix screens and LCD screens. So, what is the difference between dot matrix screen and LCD screen?

1. Different display principles

Bitmap screens use multiple small dots to represent information. Each DOT can emit light and dark signals from text, pictures, animations and other different information by controlling the corresponding light-emitting diodes or light-emitting tubes.boe screen manufacturer LCD screens, on the other hand, use the rotation of liquid crystal molecules to adjust their transparency to display different images and text.

2. Different display methods

The dot matrix screen uses a progressive scan method, that is, the content on the display screen is line by line, so the refresh speed develops slowly, which is not suitable for displaying images of economical and high-speed moving targets, and can easily lead to the phenomenon of shadowing. This kind of learning situation will not occur with LCD screens.lcd supplier The information technology on the entire screen is displayed by us at the same time, and the refresh rate is much faster than that of dot matrix screens, and it will not affect the shadow phenomenon.

3. Different resolutions

Because a dot matrix screen is more compact than an LCD screen, its resolution is relatively high and more information can be displayed on the same size screen.oled supplier LCD screens, on the other hand, have relatively low resolution and require a larger screen size to display more information.

4. Different energy consumption

Since the dot matrix screen needs to control each dot matrix one by one, its power consumption will be greater and it will be more likely to generate heat during operation, so it generally needs to be equipped with heat sinks and other heat dissipation measures. The LCD screen can achieve high-brightness display effects in low-power consumption mode, and the modular design can also maintain low heat generation.

Generally speaking, they each have advantages and disadvantages, and there are many different application scenarios. For zero-average users, the LCD display and usage experience are better, and for some very demanding occasions, a grid screen is required.
