WF0128BTYAA4DNF10 – Winstar LCD-TFT display.

The WF0128BTYAA4DNF10 is a 1.28″ round IPS TFT-LCD module with a 240×240 pixel capacitive touch panel. This circular TFT display consists of an IPS TFT-LCD panel built from the GC9A01 driver IC, which can communicate via SPI interface and is equipped with a capacitive touch panel supporting I2C interface.

The WF0128BTYAA4DNF10 features an IPS panel, which has the advantage of higher contrast, a true black background when the display or pixels are off, and a wider viewing angle: left:80 / right:80 / up:80 / down:80 degrees (typical), a contrast ratio of 1000:1 (typical value), a brightness of 320 nits (typical value), and a panel with an anti-glare surface.

The supply voltage for analog (VCI) ranges from 2.65 to 3.3 V, typical value is 2.8 V. It can operate at temperatures from -20 ℃ to + 70 ℃ and storage temperatures from -30 ℃ to + 80 ℃. Round TFT display modules are suitable for compact devices such as wearables and smart home applications.

Full observation angles

Full observation angles

Using an IPS/MVA (or a variation thereof) matrix, the display is readable from all angles. There is no grayscale inversion effect that characterizes popular TN matrices. Also, the decrease in contrast when increasing the viewing angle is much lower.

High brightness (wide format)

High brightness

High brightness of the image (high brightness) is a feature that is extremely useful when the display is in bright sunlight. With this functionality, the content displayed is fully readable by the user. High Brightness displays can be successfully used, for example, in exhibitions, kiosks, on trains and buses, as digital signage, or as part of other outdoor solutions.
