LCD-H401C71TR

LCD-H401C71TR is a type of display module, which is mainly classified as LCD, OLED Character and Numeric. It has wide applications and the working principle is an interesting topic to understand. This article will brief on some common application fields and the internal working principle of LCD-H401C71TR.

The display module LCD-H401C71TR belongs to the segment LCD family. It has a size of 4x20 characters, working temperature-20°C to +70°C and bottom and yellow surface with white characters. LCD-H401C71TR is manufactured by TOPRO Technology Co. Ltd, and the model number is H401C71TR-CN. This display module is designed to be used in different application fields such as electronic message board, street name signboard, running time graph, moving speed dashboard, etc.

In terms of working principle, this LCD display module uses three thin film transistor substrate layers. The topmost layer is the substrate layer, the middle layer is the thin film transistor and the bottom layer is the polarizer. When powered on, the electrical current flows through the thin film transistors and along the polarizers forming the required characters. The polarizers also help in refining contrast and brightness of the characters.

The thin film transistor has four main parts, namely the source, drain, gate and the channel. These components work together to limit the flow of electric current, hence controlling the amount of electrical charge passed through the LCD. This process of controlling the electrical charge helps in forming characters on the LCD. Additionally, the transparent conductive sections of thin film transistor also help in forming columns and rows of display.

There are several advantages of using LCD-H401C71TR display module such as its versatility, low power consumption, wide temperature range, low cost and high performance design. These features make it an ideal choice for applications such as automotive, medical and industrial. It can also be used for gaming, advertising and signboard purpose.

In conclusion, LCD-H401C71TR is a display module mainly classified as LCD, OLED Character and Numeric. It has wide applications and the working principle involves thin film transistor, polarizers, and controlling the electrical charge. The advantages of using LCD-H401C71TR display module are its versatility, low power consumption, wide temperature range and high performance design, which make it suitable for applications such as automotive, medical, industrial and gaming.
