Embedded High Voltage

UMC offers the foundry industry’s broadest portfolio of eHV solutions to accommodate various LCD driver sizes and also for other displays or non-display-related applications.

Our mobile display driver IC (DDI) solutions comprise of single-chip devices for CSTN, TFT, and OLED displays widely used in the mobile segment. UMC’s eHV solutions offer leading-edge technology, devices, and the necessary IP at the lowest power consumption levels. With current mobile communication devices moving towards narrow bezel or no bezel displays, UMC pushes the SRAM cell size limitation with its eHV process to help customers strengthen their SDDI competitiveness and capitalize on this trend. For example, the ultra-small SRAM bit cell for our 55nm eHV process has been improved to help facilitate SDDI designs for smartphone panel resolutions exceeding that of Full-HD or WQXGA. To date, we have shipped hundreds of thousands of wafers using our eHV process.

For the large panel DDI solutions, UMC provides high performance logic devices and aggressive metal rules for higher channel counts, color depth, and fast clock rate applications. For these ICs, UMC offers both the technology and design support solutions to meet modern display requirements.

UMC can also provide a wide span of process nodes for e-Paper display drivers, touch control line drivers, 3D applications, etc. UMC's comprehensive eHV technologies meet the demanding requirements for a broad range of today's display applications to deliver high performance, superior display characteristecs, the lowest power consumption, and in the shortest time-to-market.
