DISPLAY VISIONS EA TFT024-23ATNN 2.4-inch TFT colour display is suitable for mobile use due to its low energy consumption. Device requires 10mA power consumption at 3.3V and shows sharp contrasts even in sunlight. It is very easy to read both with and without backlight. Without backlight, the power consumption is 35mW. During an eight-hour working day, this burdens a LiPo battery with no more than 75mAh. The positive TFT panel with a white background can be operated both in colour and in black and white. As a transflective display, it also uses the incident light for a high-contrast display in addition to the integrated backlight. Even in bright sunlight, the display can therefore be clearly read from wide angles. The resolution of the 2.4 inch display is 240×320 RGB pixels. It is a total of about 43mm wide and 60mm high. It is connected to the driver electronics via a FPC cable. In addition to the standard RGB interface, a pin-saving 4-wire SPI interface and a parallel µC data bus with 8- or 16-bit width are available.
