Description
WF0154ASAAA4DSN0 is a 1.54-inch square IPS TFT LCD with a resolution of 240x240 pixels and an IPS panel. This square IPS TFT has the advantages of higher contrast, a full black background when the display or pixel is off, wider viewing angles of Left:80 / Right:80 / Up:80 / Down:80 degrees (typical), a high brightness of 850 nits (typical value), 900:1 contrast ratio (typical value), an anti-glare glass surface.
This 1.54" display is built-in with ST7789T3-G4-1 driver IC that can communicate via SPI interfaces. The supply voltage of the analog is from 2.4V to 3.3V, with a typical value of 2.8V. It can operate at the temperature range from -10℃ to +60℃, and its storage temperature range is from -20℃ to +70℃. This WINSTAR high-brightness 1.54-inch LCD is suited for wireless microphone system, coffee scale, personal, and pulse oximeters.
