Automotive

The number of displays on the vehicle is increasing, and enlargement and curvature are also drawing attention.
LX Semicon’ latest display-driven technology enables a display design optimized for complex and diverse vehicle environments.

Chipset

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.

TMLS (Touch Modulation Level Shifter): TMLS is an IC that combines the Touch Modulation IC, which maximizes Touch per-
formance by synchronizing the Gate and VCOM voltages with the Touch signal while
Touching, and the Lvel Shift function, which converts the TFT Turn-on/off voltage to
Gate Clock for Gate in Panel(GIP).

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.

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.

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.

TDDI (Touch and Display Driver Integration): Touch and Display Driver Integration(TDDI) is an integrated IC that combines a
Display Driver IC(DDI) that displays on-screen video signals from the AP and
Touch Controller IC that detects changes when touching the screen with a
finger or pen and sense position/angle/sensitivity.
