DDI (Display Driver IC)
The Display Driver IC is a chip for driving the
screen and converts the digital signal received
from the Timing Controller into analog voltage
and transmits it to the panel. LX Semicon
provides Source Driver IC and Gate Driver IC for
display driver.
T-Con (Timing Controller)
The Timing Controller separates the
data delivered by the system into digital
image data and control signals and
forwards it to the Driver IC.
PMIC (Power Management IC)
The PMIC changes the power applied by
the System to the various voltages
required to operate the OLED panel and
provides stable control.
HV Level Shifter
It converts and transmits the TFT
Turn-on/off voltage (VGH, VGL) from the
PMIC to the Gclk suitable for Gate in

RealTouch (LCD In-Cell Touch)

SRIC (Source Driver+Touch Readout)
SR(Source Driver+Touch Readout)IC
combines the function of the Source Driver IC,
which drives the TFT, and the Readout IC,
which detects touch signals and transmits
them to the Touch IC.
T-MCU (Touch MCU)
Touch MCU is a Micro Controller Unit(MCU) that
converts and processes Touch Data from Readout
IC or SRIC into digital signals.
TMIC (Touch Modulation IC)
TMIC maximizes Touch performance by
synchronizing and modulating Gate and VCOM
voltage with the Touch signal during Touch
