Description
WF0340ATYAB7MNN0 is a 3.4-inch Circular Screen IPS TFT Display with a resolution of 800x800 dots. It uses IPS (In-plane Switching) technology to achieve fast and stable response time, higher frequency transmittance, and better color performance. The most significant advantage of IPS is the wider viewing angles of up: 85/ down: 85/ left: 85/ right: 85 degrees. This circular TFT display has the module dimensions of 94.9 x 96.95 mm and the active area of 87.6 x 87.6 mm. It boasts a built-in ILI9881C driver IC, supporting 4-wire MIPI interfaces. The contrast ratio of the module is 1200:1, the brightness is 300cd/m2 (typical value), the analog circuit voltage is 3.3V (typical value), and the logic circuit voltage is 1.8V.
The operating temperature range of this 3.4" LCD is from -20℃ to +70℃, and the storage temperature range covers from -30℃ to +80℃. The circular TFT LCD display is suitable for home appliances, electronic alarm clocks, cocktail machines, and other products requiring circular display screens.
