When it comes to liquid crystal display modules, outsiders may not be familiar with it, but when it comes to LCM, I believe many people will feel familiar with it. Yes, it is a kind of liquid crystal display device, connector, integrated circuit, backlight, etc. that can be matched together. Without it, the connection function of LCD will not be completed. In recent years, with the maturity of LCD technology, its price is getting lower and lower, so how can we choose a suitable LCD module? Let’s take a look together:
1. Data to be considered in model selection
To choose a suitable LCD module, you first need to consider the following three key indicators, display resolution: the number of pixels must be greater than the number of pixels required by the product display content; external dimensions: the size must adapt to the structural size of the product chassis; circuit coordination: the circuit The selection will be directly related to the circuit design of the MPU system. The circuit combination needs to compare the MPU system resources and the module circuit characteristics, so as to make a comprehensive consideration.
2. Content Priority
The content priority method is to select standard products by first meeting the requirements of the display screen, and use the structure to balance. This method is used when the chassis structure of the product leaves a large selection space for the module, or the chassis can be laid out with reference to the size of the module. This method will satisfy the display.
3. Structural priority method
The structure priority method is to select standard module products with external structure dimensions. This method is used when the size of the chassis structure of the product has been fixed, and there is little choice for the size of the module. This method will satisfy the structural dimensions.
4. Customized modules
If there are special requirements on the display and structure of the liquid crystal display module, and the cost of mold opening is affordable in terms of the cost of the whole machine, a customized module can be used. The advantages of customized modules are specificity, protection from manufacturers and protection from product competition in the market, and optimization of product structure. Customized modules are specially designed according to product characteristics and come in many forms.
How to choose the right LCD module? On the whole, customized liquid crystal display modules are better, and mass production is more convenient, and can obtain better application effects and high performance-price ratio of products.
