The Differences Between UART LCD Screen and USRT LCD Screen

UART LCD screen and USRT LCD screen have differences. We’ve all heard of UART screens and USRT screens in our daily lives, but do you know what the differences are? below, as a LCD screen supplier, we will explain the differences between UART LCD screens and USRT LCD screens from four aspects, hoping to be useful to everyone.

1. Differences in writing speed between UART LCD screens and USRT LCD screens

The LCD screen is composed of pixels, and the structure above the UART LCD screen and USRT LCD screen determines the operation speed of these pixels. The writing speed of the USRT LCD screen is determined by the speed of the upper microcontroller. The faster the upper microcontroller is, the shorter the writing time is. The writing speed of the UART LCD screen is mainly related to the baud rate of the UART port, not to the speed of the upper microcontroller.

2. Differences in display colors between UART LCD screens and USRT LCD screens

The performance of the upper microcontroller determines the choice of the USRT LCD screen. It is suitable for displaying 256 colors with an 8-bit microcontroller. 16-bit and 32-bit microcontrollers can achieve 65K colors. The display color of the UART LCD screen is independent of the upper microcontroller and is generally 65K  colors. Choosing a wholesale TFT LCD display that offers the best display colors based on the application is crucial to enhance the user experience and overall product performance. A reputable wholesale supplier should provide options that cater to different color display preferences to ensure that each customer can provide the desired visual experience for their product.

3. Differences in application scenarios between UART LCD screens and USRT LCD screens

The UART LCD screen is suitable for products with colorful, complex interfaces, lots of displayed text, and low-performance upper computers. The USRT LCD screen is suitable for products with simple interfaces, real-time data acquisition and display, and high-speed drawing. Therefore, choosing the best wholesale TFT screen for a particular application scenario is crucial in ensuring that the end product meets the desired performance specifications. Wholesale suppliers must provide a variety of options to cater to the diversity of application scenarios and provide customized solutions for their customers.

4. Differences in system structure between UART LCD screens and USRT LCD screens

The UART LCD screen mainly includes a UART communication device, Flash controller, LCD display controller, SDRAM controller, bus controller, etc. It receives commands sent by the upper computer through the UART port, executes the corresponding display operations after translation, and the pictures and character libraries are saved in Flash and called directly. The USRT LCD screen is mainly composed of an LCD display controller, SDRAM controller, USRT controller, etc. Under clock control, it temporarily stores and displays the predetermined data sent by the USRT interface, showing what information is sent.

Through the above analysis, the price of the USRT LCD screen is cheaper than that of the UART LCD screen. The above is a simple explanation and analysis of the differences between UART LCD screens and USRT LCD screens from four aspects by the LCD screen supplier.
