Abstract

This article describes a software-driven hardware device capable of reading a computer screen (monochrome or color) and converting this information into hexadecimal values which can then be checked for accuracy against known values contained in the software. This device will plug into an IBM Personal Computer (PC) I/O slot and have the capabilities of testing up to seven display drivers at once. Presently a method of "burning in" a PC system board using a burn- in chamber has shown that the burn-in process greatly reduces any defects which would otherwise show up in the field. This burn-in process requires a method of testing the display cards inside the chamber. The display cards are tested dynamically in a sealed environment in which the temperature is ramped up and down.
