Hi, Some days ago I posted some messages requesting info about the Sharp LM64P791 640x400 B/W LCD. After reading lots on posts, datasheets and executing searching on all internet search engines available , I decide to contact Sharp.... After telling a small lie , I got this: Code: That Sharp LCD is not a standard part number. It may be a custom product, sold originally in Japan to an OEM manufacturer. I do not have Specifications on custom display modules. Without the original custom specification, I cannot cross it to a standard part number. You will need to contact that OEM company for assistance and support. It may be a display that was sold in Europe or Japan or the Asia/Pacfic Regions. My product database is ONLY for those standard products marketed in the Americas . I have no documentation to support it. You will need to contact the Sharp support organization in your Region. Use the Sharp Global Locator - [url]http://www.sharp-world.com[/url] to locate your regional Sharp office. The only other suggestion would be to try companies that deal in outdated displays, backlighting, equipment, and accessories (this is not an endorsement by Sharp of these companies, but rather a direction you might explore to satisfy your requirements): Earth Computer Technology. 949-248-2333 [url]http://www.flat-panel.com[/url] [url]www.Laptopking.com[/url] for laptop repairs.

Rich French Applications Engineer - Technical Help Desk Sharp Microelectronics of the Americas Phone: (360) 834-8067 Fax: (360) 834-8984 email: [email]frenchr@sharpsec.com[/email] Also included a datasheet for the LM64P74 a 640x480 B/W LCD dated on 1992. In my investigation I got a datasheet for the LM64P70 lasted revision October 1990. Take it Here!! If you see the serial on the LM64P791, in my case, it's 91G1085Y, acording to Sharp that serial means: 91 <- Year of manufacturing G <- Month A=Jan, B=Feb,....,L=Dec. In my case G=July 1085 <- Serial Number Y <- Factory Also, Sharp made this LCD as a OEM for Sony when he builded the Mac PowerBook 100 for Apple in 1991 (BTW, the first portable Mac , and the first portable using a small SCSI hard drive .) After reading both datasheets, the right interface for this LCD, should be a Parallel. Aditionaly, I don't know if an existing app like LCDStudio shouldn't support it. Maybe I must develop my own app So, if you have time and one of this LCD, try as me.... Greetz Darius
