US Patent:

57710287, Jun 23, 1998
Filed:

Sep 7, 1995
Appl. No.:

8/525338
Inventors:

Scott W. Dalton - Cypress TX
Doyne L. Metz - Cypress TX
Assignee:

Compaq Computer Corporation - Houston TX
International Classification:

G09G 500
US Classification:

345 3
Abstract:

A method that identifies the type of LCD panel used in a portable computer system based on the frequency of the oscillator signal of the DC-to-AC inverter in the LCD panel. In this method, only one signal is routed from the LCD panel to the base unit of the portable computer system for the purpose of panel identification. The inverter oscillating signal is used to increment a counter during power on operations. A system counter, which is clocked by a system clock, is used to determine the number of system clocks needed for the panel identification counter to reach a predetermined count. That number is compared with the entries of a table, in which each entry corresponds to a type of LCD panel. In this manner, the type of LCD panel can be identified based on the frequency of the inverter signal. A corresponding entry in a second table is accessed to obtain a table entry for the identified LCD panel to a full table of LCD panel parameters.

Filed:

Jan 27, 1994
Appl. No.:

8/188373
Inventors:

David R. Evoy - Tempe AZ
Lawrence D. Gould - Mesa AZ
James R. Edwards - Tomball TX
Donald G. Scharnberg - Pasadena TX
Doyne L. Metz - Cypress TX
Assignee:

VLSI Technology, Inc. - San Jose CA
International Classification:

G06F 1300
G06F 1310
US Classification:

395652
Abstract:

A shared keyboard and system ROM uses a single ROM for both the keyboard and the system operating system information (BIOS). The shared ROM is never simultaneously used for both of these functions. At initial boot-up, the system processor executes from the shared ROM to copy the system BIOS information to the system Random Access Memory DRAM. Once this copying has been completed, the shared ROM then is used by the keyboard subsystem. Different address ranges are employed in the shared ROM for the keyboard information and for the system BIOS.
