GLT24064-FGW-VPT Application Field and Working Principle

GLT24064-FGW-VPT (Graphic Liquid Crystal Dot Matrix Display), a type of display module, uses transistors and liquid crystals as its primary components to display characters and graphics. GLT24064-FGW-VPT modules consist of a display controller and a liquid crystal dot matrix with a total of 240×64 addressable dots. It is widely used in the field of industrial display, automotive display, and home appliance display.

Application Fields

GLT24064-FGW-VPT is most often used in industrial displays, automotive displays, and home appliance displays, among other applications. This type of dot matrix display is often preferred because of its advantages such as low power consumption, wide viewing angle, and no need for backlighting. In industrial applications, a GLT24064-FGW-VPT module can be used to display information such as temperature, pressure, or flow rate in an industrial system. In automotive applications, it can be used in navigation systems, entertainment systems, temperature gauges, and fuel gauges. In home appliances, it can be used to display text and graphics in phones, TVs, air conditioners, and other home appliances.

Working Principle

A GLT24064-FGW-VPT module consists of two main components: a display controller and a liquid crystal dot matrix that consists of 240×64 addressable dots. The display controller receives data from the host device and stores it in RAM (Random Access Memory). The controller then sends this data to the liquid crystal dot matrix, which is connected to the controller through an internal bus. The matrix, in turn, processes the data and displays the corresponding character or graphic in the appropriate pixel position, where each position is addressable by the controller.

A dynamic memory is used to store data in the GLT24064-FGW-VPT module. This memory is split into two sections, one for character data and one for display data. The character memory stores data that keeps track of what character should be displayed in its corresponding pixel position. Meanwhile, the display data section stores pattern data that determines how each pixel should be displayed. The controller uses this data to control the transistors in the matrix, which in turn control which pixel positions are illuminated, thus creating the desired character or graphic.

Conclusion

The GLT24064-FGW-VPT module is a type of digital display module that uses transistors and liquid crystals as its primary components. It can be used in industrial, automotive, and home appliance applications. The module consists of two main components: a display controller and a liquid crystal dot matrix. The display controller receives data from the host device and stores it in RAM. The controller then sends this data to the matrix, which processes it and displays the corresponding character or graphic in the appropriate pixel position. A dynamic memory is also used to store data within the module. With these components, the GLT24064-FGW-VPT module is well-suited for displaying text, graphics, and other information in an array of applications.
