WF28KTLAJDNT0 is a 2.8-inch portrait mode TFT-LCD module featuring a 4-line SPI interface and a built-in Resistive Touch Screen. It offers a resolution of 240x320 pixels and integrates the ST7789V driver IC. This module has a glare surface, 6 o'clock viewing direction, and 12 o'clock gray scale inversion with a contrast ratio of 500:1.
WF28KTLAJDNT0 delivers a typical brightness of 350 cd/m² and supports a wide operating temperature range from -20°C to +70°C (storage -30°C to +80°C). The 4-line SPI interface simplifies wiring and reduces pin count, making it suitable for compact system designs. With a long-life LED backlight (50,000 hours) and stable performance, this display ensures durability and reliability in continuous operation environments.
The compact and lightweight design allows for easy integration into space-limited devices. This 2.8-inch TFT display is well-suited for industrial control panels, handheld devices, security systems, and consumer electronics. Optional models without a touch panel or with higher brightness are also available upon request.
