Touch Controller IC
Touch Controller IC is an IC that sense changes when touching the screen
with a finger or pen, senses position/angle/sensitivity,
and forwards it to the Application Processor(AP).
OLED DDI (OLED Display Driver IC)
The OLED DDI consists of a Timing Block that transmits video signals
from the AP to the drive block, a Drive Block that operates the TFT, and a
Compensation and Quality Improvement Block. LX Semicon’ OLED DDI
resolves staining phenomena caused by TFT process and OLED depo-
sition deviation and deterioration caused by organic material characteris-
tics through its own compensation/definition improvement algorithm
and implements a clearer screen.
