<p>There are two types of LCD modules on the market, one is a pen-segment LCD module, and the other is a <a href="https://www.genyulcm.com/dot-matrix-lcd" rel="noopener noreferrer" target="_blank">dot matrix LCD</a>. What are the differences between these two modules? Let's compare them below.</p><p><br></p><p>The pen-segment liquid crystal module directly etches the pattern that you want to display on the ITO glass. In this case, the graphics displayed on the glass panel are fixed, and what graphics are displayed at which positions are fixed and unchangeable. But for the dot matrix liquid crystal module, it is not a fixed pattern engraved on the ITO glass, but a rectangular dot matrix in rows. If you want to display some patterns at this time, you must program through software. Each graphic is composed of a small rectangle. Therefore, there is still a big difference between the pen-segment LCD module and the dot matrix LCD module. The pen-segment liquid crystal module is limited when it is used. The content it displays is fixed. If you want to change to other patterns in the same position, it won't work. The dot matrix LCD module is different, the content displayed can be ever-changing, and customers can just debug the software according to their needs.</p><p><br></p><p>Of course, the pen-segment LCD module is relatively simple for development and design, and does not require complicated circuit design and software debugging. If the customer does not need to change the display content in the application, then choose the pen-segment LCD module. The dot matrix liquid crystal module is different. It is relatively more complicated to develop. Although it is complicated to develop, customers can use it flexibly to meet the needs of all aspects. So, which one is better, pen-segment LCD module or dot matrix LCD module? It depends on the needs of the client. It doesn't matter which one is good or not, just meet the development needs.</p><p><br></p><p>In summary, the pen-segment LCD module and the dot-matrix LCD module each have their own advantages, as long as we clearly recognize the differences between the pen-segment LCD module and the dot-matrix LCD module in various aspects, and then combine our practical applications, Make a reasonable and correct choice.</p>
