AMOLED bias supplies

AMOLED bias supplies are designed to excel in contrast ratio and color gamut while maintaining efficiency. The devices cover screen sizes from 1-inch wearable solutions to notebook panels.

LCD bias supplies

LCD bias supply solutions provide essential rails such as AVDD, +/-AVDD, VGH and VGL to supply the gate and source drivers of the display panel. 

LCD level shifters

Level shifters support gate-in-panel (GIP) display technologies, which are typically more cost-efficient and enable narrower screen bezels than non-GIP displays.

LCD gamma & VCOM buffers

Programmable gamma buffers shape a display's color curve for more accurate color reproduction.
