T-CON Embedded Driver IC for Next-Generation Notebook Display

OMNIVISION Display Solutions’ CRX2000A T‑CON embedded driver IC (TED IC) is designed for 2160 x 1350 (LTPS), 1920 x 1080 / 1200 / 1280 (a‑Si, Oxide, and LTPS) LCD TFT panels and is the best fitted solution for low cost and low power consumption. CRX2000A can be mounted on COG (chip on glass) area and supports 1/2/4 lanes eDP 1.4b MSO (multi-SST operation) input interface with HBR, R243, R216 and RBR, and 2880ch source driver output.

CRX2000A provides a 1‑chip solution for a‑Si, Oxide, and LTPS panels. It can also support a 2‑chip solution for panels with VESA MSO feature, up to 2880 x 1920 with a‑Si dual gate or LTPS MUX2/3.

CRX2000A supports an external I2C EEPROM read/write function. It also supports accessing internal registers by eDP I2C-over-aux, I2C. An SDK (system development kit) is available to enable fast light-up, fine-tune and optimize panel performance for customers.
