![]() Overall it makes me wonder if adding a $15 Wiznet W5100 ethernet interface is the way to go, that way anything that supports TCPIP and a terminal emulator can be used to display information. Android tablets don't support any kind of serial interface. Chromebooks appear to have some degree of support for USB to serial adaptors and the "Beagle term" terminal plugin for the Chrome browser should in theory work, but I don't want to spend the money only to find out that it doesn't. Second hand terminals from yesteryear are available, but use CRT screens and are therefore bulky and power hungry. As far as I can tell VT100 style terminals with LCD screens don't exist. To go beyond 7" requires the use of a single board Linux computer running a terminal emulator, or a laptop running Windows/Linux. To summarise, 4dsystems and Nextion have 'smart' displays that go up to 7" in size, although setting these up seems like a major development in itself. you can buy them split in rows like these ones here: or as graphical where you can flip any pixel on the screen: Most of these work with 4 bit or 8 bit parallel and some have chip select so it's easy to work with them, some have i2c, spi etc Here's some examples, they're all 10-14mm tall digits : Lots of alphanumeric LCD displays that have big fonts, up to around 14.5mm per digit, and transmissive or transflective so you can choose if you want to make them with backlight or not. Smart home appliances: smart home, household water purifier, smart toilet, massage chair, microwave oven, coffee machine, towel dryer, range hood, Gas purifiers, water heaters, fascia guns, home energy storage equipment, etc.Like others said, you could use 14-16 segment digits to display your numbers, and you could add a small microcontroller in your design to act as a "driver" to do the multiplexing (if needed) for your 20 values, but it could get expensive. With the rapid development of the smart home industry, the serial screen industry has been recognized by the majority of electrical appliance manufacturers and users due to its advantages of low cost and high performance.įor example, the following common products are popual in UART solutions: ![]() This pin is the busy status output of the serial port screen, and the master control terminal can know whether the serial port screen is No is busy ![]() This is the data input port of the Uart serial communication interface, which is used to receive the TX sends command signal This is the data output port of the Uart serial communication interface, which is used to transmit command signals to the master RX of control terminal MCU It can be updated via USB interface MCU program and external SPI Flash data. This is the signal of USB data terminal DP. This is the signal of USB data terminal DM. , use the display screen to display relevant data,PassWrite parameters or enter operating instructions through input units such as touch screens, buttons, and mice, thereby enabling information interaction between the user and the machine.wideIt is widely used in various display fields such as industrial automation, smart home appliances, transportation rails, data computer rooms, charging piles, power medical, national defense and security, and shared equipment. Serial screen, a configurable secondary development of intelligent serial control display, refers to a TFT color LCD display control module with serial communication, which can be connected to external equipment such as PLC, frequency converter, temperature control instrument, and data acquisition module. And the working temperature is -20 ~ +70☌, storage temperature is -30 ~ +80☌. The backlight design for this 7 inch LCD is 30 LEDs, 200mA, typical voltage is 9.6V. TSD could also make the customized design basing on IPS solution. ProLCD-T070N01 is 7 inch 800x480 resolution TFT lcd display with serial UART interface panel, it's TN display with 12 'o'clock viewing angle.
