FAQs about 3.5″ capacitive touch screen
Q1: What interfaces does the ST7365P support?
A: It supports 8080-series 8-bit, 9-bit, 16-bit, and 18-bit parallel MCU interfaces. The FPC-40 pins are pre-configured for direct connection with mainstream MCUs.
Q2: Will video playback lag with an MCU interface?
A: The ST7365P has 345.6KB of built-in GRAM, which can store one full frame of image. With a 16-bit parallel interface and a high-performance MCU, it can achieve 15-20fps, sufficient for simple animations. For higher frame rates, an RGB interface screen is recommended.
Q3: Is 500cd/m² brightness sufficient for outdoor use? How to adjust the backlight?
A: It is clear enough under scattered outdoor light. The capacitive touch screen’s backlight can be adjusted using a PWM signal, with a frequency recommended above 1kHz to avoid flickering. Reducing brightness can extend battery life.
Q4:What viewing experience does IPS TFT technology bring to this 3.5 inch TFT display?
A: A major highlight of This 3.5 inch TFT display is its IPS (In-Plane Switching) technology, which provides a 178-degree viewing angle. This means that regardless of the viewer’s position relative to the screen, colors and contrast remain consistent and vibrant, without noticeable color inversion or washout. Therefore, it is ideal for applications where multiple people are viewing the screen simultaneously or where viewing from different angles is required.
