EDID data for the LG LP156WH3 15.6-inch laptop LCD panel, a raw 256-byte binary. EDID is stored in a small EEPROM on the panel and tells the system the supported resolution and timings; a corrupted copy can cause a blank screen or wrong resolution. Write it to the panel EEPROM with a programmer that supports I2C memories. Make sure your panel really is an LP156WH3, and save the existing contents first, since EDID can vary between panel sub-revisions.
