4DLCD-FT843 is an LCD display module which belongs to a new series of LCD display modules, that is, Display Modules - LCD, OLED, Graphic. This module is currently produced and marketed by 4D Systems, which specializes in the manufacture and supplies of industrial-grade LCD display modules.

4DLCD-FT843 is generally applicable in the areas where standard LCD display modules cannot provide the desired display effect. The features with 4DLCD-FT843 are where other types of LCD display modules are not able to fulfill the requirements, such as wider viewing angle, better transmission efficiency and lower power consumption.

In terms of the application field, 4DLCD-FT843 is widely used in many industrial applications, such as industrial equipments, access control systems, automotive applications and infrared imaging systems, etc. And this module also can provide satisfactory display performance in the following fields: laboratory instrumentation, medicine and health, household appliances and robots etc.

There are a few key areas in the working principle of 4DLCD-FT843 which need to be highlighted. Firstly, it has well-organized LCD pixels array which has connections to gate driver and source driver. The gate driver uses switching signals to control the voltage on the the gate control lines, while the source driver passes electric current to the pixels based on the switching signals.

Secondly, the backplane has two layers, a thin film transistor array layer and a liquid crystal layer in between them. Thin film transistors, TFTs, are responsible for switching the voltage to and from the pixels, whereas the liquid crystal layer is responsible for changing its polarizing angle when in contact with a voltage accordingly.

Thirdly, the electronic circuit is responsible for interpreting the images and commands into electronic signals, which send the electric current signals to the thin film transistor array. The thin film transistor array in turn will switch the appropriate voltage to the correct LCD pixel.

Finally, the power management circuit is the key for 4DLCD-FT843 to achieve ultra-low power consumption. It turns on and off the display at a very low power consumption level in order for the module to achieve its advertised consumption level, which is 1.6mW in standby mode.

In short, 4DLCD-FT843 is a practical, efficient and low-power consuming LCD display module, which can provide wide application area, good transmission efficiency and excellent display effect. All these features make it an ideal choice for industrial applications and many other fields.
