Display Technology
IPS Panel Architecture In-Plane Switching technology sets this module apart from conventional TN displays. The liquid crystal alignment enables consistent color reproduction and contrast ratios across all viewing angles. Users experience the same visual quality whether viewing straight-on or from extreme angles—critical for handheld devices that constantly shift orientation.
Normally Black Mode The panel operates in normally black configuration. When voltage is removed, pixels default to black. This architecture delivers deeper blacks, higher contrast, and reduced light leakage compared to normally white alternatives. Power efficiency improves in dark interface designs.
Active Matrix TFT Thin-Film Transistor active matrix addressing ensures each pixel receives dedicated switching control. No shared electrode crosstalk. No ghosting. Sharp edges on fast-moving graphics.
