OLED gradient color

Quick answer：

OLED gradient color refers to the ability of Organic Light Emitting Diode (OLED) displays to produce smooth transitions of color intensity across their screens. This is achieved by using a matrix of red, green, and blue sub-pixels that can emit light at varying intensities, creating a gradient effect. OLED technology is known for its high contrast ratio and ability to display deep, vibrant colors, making gradient color displays particularly appealing for visual content.
