You can rest assured to buy customized High Brightness Tft Lcd Display from us. High-brightness TFT displays are equipped with powerful LED backlights and can reach brightness of up to 4500cd/m².
In bright light environments, such as shop windows or outdoors in direct sunlight, TFT displays with normal brightness are often difficult to see and appear dim. Our high-brightness TFT displays use bright backlights and special polarizers to display content clearly under these conditions.
The WF40ESWAA6DNG0 is a high brightness 4-inch square IPS TFT LCD display module with a projected capacitive touch screen (PCAP) and a resolution of 480 x 480 pixels. The module supports a 24-bit RGB interface and uses an IPS panel with a typical wide viewing angle (left: 80 / right: 80 / top: 80 / bottom: 80 degrees), a contrast ratio of 800:1, a high brightness of 800 nits, and an anti-glare surface with an aspect ratio of 1:1.
The WF40ESWAA6DNG0 square TFT LCD display module integrates the ST7701S driver IC with a supply voltage range of 2.5V to 3.6V, with a typical value of 2.8V. The WF40E model can operate normally in an environment of -30℃ to +80℃, and the storage temperature range is also -30℃ to +80℃.
