Introduction
Description:
HW-034P0W002-01 is a circular TFT LCD (liquid crystal display) with a 3.4-inch overall dimension. Boasting IPS (In-Plane Switching) technology, this display ensures exceptional visual performance with a resolution of 800x800 pixels and an impressive screen color depth of 16.7 million.
Powered by the JD9365 driver IC, this display provides reliable and advanced control. All O'clock viewing direction enhances visibility from any angle, making it versatile for various applications. The interface is established through MIPI, ensuring high-speed and efficient communication with compatible devices.
The backlight system comprises 8 LEDs, individually rated at 20mA, totaling 160mA, resulting in a remarkable LCM brightness range from a minimum of 800 cd/m² to a typical 1000 cd/m². This ensures vivid and clear visuals even in challenging lighting conditions. The display maintains a minimum LCM uniformity of 80%, guaranteeing consistent brightness across the entire circular screen.
