TFT-H030A14WQEST1N40-V0-0 | 3-inch transflective TFT LCD display 240x400 resolution sunlight-readable low-power display
Product Overview
This 3-inch transflective TFT LCD display is engineered for applications where readability in bright outdoor conditions and low power consumption are critical. Combining a 240x400 resolution with transflective technology, this 3-inch transflective TFT LCD display delivers clear, consistent images in direct sunlight while drawing minimal current — making it an ideal choice for outdoor equipment, industrial control systems, and portable devices that demand reliable performance in challenging environments.
Transflective Technology for Sunlight Readability
Unlike conventional transmissive LCDs that become washed out under strong ambient light, this 3-inch transflective TFT LCD display uses a reflective layer that harnesses natural light to enhance visibility. The result is a sunlight-readable screen with an omnidirectional viewing angle, ensuring that operators can read critical data from virtually any position — even in direct sunlight. With a backlight brightness of 120 cd/m², the display maintains excellent contrast and clarity both indoors and outdoors, reducing the need for high-power backlighting and extending battery life in portable applications.
Low Power Consumption
Power efficiency is a defining strength of this 3-inch transflective TFT LCD display. Operating at a 3.3V supply voltage and leveraging transflective optics that rely partially on ambient light, the module significantly reduces power draw compared to standard transmissive TFT panels. This low-power design makes the 3-inch transflective TFT LCD display particularly well suited to battery-operated handheld terminals, remote monitoring equipment, and field instruments where every milliamp matters.
Robust Specifications for Industrial Use
The display features a 240x400 pixel resolution across a 3-inch active area, driven by the ST7365P driver IC and connected via a 40-pin FPC with SPI/MCU interface for flexible integration. Built for demanding environments, it offers 8KV electrostatic discharge protection and operates reliably across a wide temperature range of -30℃ to 80℃. These specifications make this 3-inch transflective TFT LCD display a dependable solution for outdoor equipment, industrial control panels, and rugged handheld devices.
