This 4.3-inch low-power UART smart display, featuring 480*272 resolution and IPS precise capacitive touchscreen, centers on "long battery life + accurate touch interaction", suitable for portable industrial detectors, handheld medical monitors, outdoor smart terminals and other scenarios requiring high power efficiency and operation precision. Low-power design runs through hardware and software: it adopts a low-power IPS panel with an operating power consumption of only 65mW and a standby power consumption as low as 5mW; equipped with a 1000mAh lithium battery, it can work continuously for more than 120 hours, solving the problem of frequent charging for portable devices. It also supports intelligent sleep mode, which automatically reduces brightness to 50nits when there is no operation and wakes up quickly within 0.1 seconds after touch is triggered, balancing energy saving and user convenience.
480*272 resolution and IPS technology ensure display quality: the resolution presents clear detection data curves and medical parameter tables on the 4.3-inch screen with no blurry details; IPS technology achieves 178° full-angle color consistency, allowing clear data viewing from the side when used outdoors, avoiding visual deviation under strong light. Precise capacitive touch is the core highlight of operation: it supports single-point accurate touch with a positioning error of ≤0.5mm, enabling light touches to adjust detector parameters and confirm medical monitoring data, even with thin gloves; the touch response delay is ≤0.06 seconds for smooth operation without lag, and it is equipped with an anti-misoperation algorithm to avoid false operations caused by outdoor jolts.
UART interface and compatibility are optimized: it supports baud rate adjustment from 9600-57600bps, which can be flexibly connected to the main control chips of portable devices (such as STM32L4, Nordic nRF52840) for real-time two-way data transmission; the interface has basic anti-interference ability and can communicate stably in complex outdoor electromagnetic environments; the display also supports custom touch shortcuts, allowing common functions (such as data saving and parameter reset) to be set as one-touch commands to improve operation efficiency.
In summary, with low-power long battery life, IPS HD display and precise capacitive touch, this 4.3-inch low-power UART smart display adapts to portable and outdoor scenarios, providing an efficient and intelligent display solution for devices requiring energy efficiency and operation precision.
