TFT-H078A1ZAIST7N40 | 7.8 Inch TFT LCD Display | 400x1280 Resolution MIPI DSI Sunlight Readable
This 7.8 inch TFT Displays (model: TFT-H078A1ZAIST7N40) uses the MIPI 4L interface and the ST7703 driver chip, supports 400x1280 resolution.The module uses a transmissive normally black panel, supports full viewing angle (horizontal ±80°, vertical ±80°) display, color gamut coverage of 70% (CIE1931 standard), typical contrast of 900:1, brightness of 750cd/m², and can present 16.7M colors. Its operating voltage is VCI=2.8V (typical value), IOVCC=1.8V (typical value), the backlight consists of 15 white LEDs, adopts a 3-series 5-parallel structure, the operating voltage range is 16.8~20.4V (typical value 18V), and the maximum drive current is 100mA.
The 7.8 inch TFT Displays has wide temperature adaptability, the operating temperature range is -30℃ to 85℃, and the storage temperature range is also -30℃ to 85℃. It has passed multiple reliability tests such as high-temperature storage, low-temperature operation, high temperature and high humidity to ensure stable operation in harsh environments. Its design adopts a full glass structure, equipped with a gold finger interface and FPC flexible circuit board, and supports MIPI high-speed signal transmission. The pin definition covers power supply, ground, differential data signal and backlight control, among which the LED anode (LEDA) and cathode (LEDK) need to be controlled by a constant current drive circuit.
The 7.8 inch TFT Displays provides standard initialization code, covering timing configuration, gamma correction and power management functions, and supports 540×1280 virtual resolution to meet actual display needs. Users need to center the image data with black edges on the platform to ensure complete output of the picture. This 7.8 inch TFT Displays is suitable for industrial control, medical equipment, automotive display and other fields that have strict requirements for high brightness, wide temperature performance and reliability.
