UART and USRT are opposed ideas, much like single-lane and multi-lane roads. UART communication entails sending each byte of data bitwise to the other end of the data line, while USRT, as its name implies, transmits data in parallel to the receiving end without executing multiple UART port protocols at once. UART data transmission is a more logically sophisticated process than parallel data transmission. For digital circuits, if a segment of full-color 800*480 real-time image surpasses 30fps, parallel communication must be utilized for data transfer since the data payload of UART communication cannot be compared to that of parallel communication, such as when reversing images. In general, a monochrome UART screen will be designed using IIC or TTL, however, a color UART screen's interface may be more diverse and customized based on the circumstances.
Why not use USRT to replace all UARTs? One explanation is that USRT is more expensive, but that is not the primary reason. In digital circuits, there are only two logic voltage levels: 1 and 0, which can only be direct current. This complicates long-distance transmission because DC signals attenuate more quickly during transmission and require signal correction. If USRT were employed, signal correction would be significantly more costly. Click here for 4.3 Inch High Brightness Lcd Display.
A UART display cannot manage the amount of data from a parallel device, so the displayed graphics and programs are primarily pre-written and burned into the module's memory rather than being controlled by the MCU. The MCU then transmits instruction sets to the UART device to schedule operations like changing the contents of fixed text, showing hidden layers, repositioning a control element, and adjusting the backlight power.
The advantage of industrial UART displays is that the TFT module has a highly complex graphic working environment. All display content can be processed by the module alone by transmitting scheduling instructions, eliminating the need for the MCU to provide display content data frame by frame to the screen. This opens up more design options, as both low-power MCUs and great ARM-based MCUs are compatible. For simple MCUs, such as the 51 single-chip microcomputer, the procedure is simplified. It simply needs to respond to the external device's interrupt and send instructions to the TFT module; the MCU may then forget about the rest.
Many people believe that the slow data transmission of a UART display cannot handle repeated assignments of many variables, such as a master control panel in a factory with multiple devices. However, if the project's display needs are properly understood, shortcuts and optimized coding can be identified. Apply for as few global variables as feasible and provide more conclusive code snippets. If the same operation rules are utilized, they must be created in the same scene to avoid wasting code space. Although not everyone can attain the algorithm's conciseness, it is not difficult to build a well-thought-out and appropriate code snippet.
UART displays are widely used in a variety of applications, including monochrome and color, dot matrix, and segment code. These display gadgets can be found in both factories and households. Color screens are increasingly employed in medical equipment and consumer electronics, as well as some exploration equipment and mobile devices. Analog signal sources are no longer commonly analyzed using segment code LED or LCD readings. UART display modules will be employed in a wider range of applications, including industrial switches, detection and control devices, medical beauty items, public safety, and smart homes.
Beauty equipment is a broad term for a variety of beauty devices. People's need for their image has grown steadily as civilization has solved the food and clothes problems. Various beauty devices have evolved, and market demand for them is increasing. With the rapid growth of mobile Internet technology, its penetration into numerous industries, and the ongoing improvement of beauty technology, compact personal beauty equipment and self-service beauty equipment with UART displays have emerged. The composition systems of beauty equipment vary by their application domains.
As users' expectations for display effects grow, classic digital tube displays can no longer match them. Intelligent color screen display solutions have emerged, providing clients with a better user experience. Technology delivers intelligent color screen solutions with cost advantages and powerful functionalities to the beauty industry thanks to supplier support as well as the collaboration and invention ability of excellent R&D teams. UART displays are currently popular and well-established in the beauty sector.
Compared to classic digital tube display technologies, screens have significant advantages in all aspects:
A. The smart home screen Android offers a crisper display, higher screen brightness and viewing angle, and easier operation.
B. Enabled with audio and video functionalities (Internet of Things devices) to assist new customers with operations.
C. Equipment QR code charging, real-time QR code updates, and simple payment by scanning the code with a mobile phone.
D. Integration with a cloud platform, remote back-end management, and real-time tracking of beauty ingredients stored in the equipment.
A. Communication connection: Connected to the beauty equipment's motherboard via UART communication, and typically uses built-in resistive touch owing to the operating environment.
B. Installation positioning: The main board on the screen has a hole that fits the viewing area. The screw that secures the placement hole is fixed. (There is no market-wide standard, and conventional goods can typically match customer needs with or without sheet metal shells.)
C. Configuration development: Use software development and extensive configuration software to provide clients with enough space to play independently. The Internet of Things screen includes audio and video playback capabilities, allowing users to watch movies while beautifying themselves and reducing weariness.
Beauty equipment typically has a few interfaces, primarily utilizing the following controls:
A. Text control: Displays information such as water temperature while cleaning.
B. Button control: From the Android smart home interface, press the button to transmit instructions to the customer's motherboard and complete the necessary operations.
C. Audio and video playback: The Internet of Things allows for looping audio and video, guiding users to utilize UART machine equipment, and enhancing aesthetics.
