Title: Innovations by Guillermo L Toro-Lira

Introduction

Guillermo L Toro-Lira is a notable inventor based in Sunnyvale, CA (US). He has made significant contributions to the field of technology, particularly in the development of systems for testing flat panel displays. With a total of 8 patents to his name, his work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is a high-speed electron beam-based system for testing large area flat panels. This innovative system utilizes a CRT gun to inspect substrates within a vacuum chamber. The CRT gun directs a beam of electrons at the substrate, which is partially disposed in the vacuum chamber. The vacuum chamber is equipped with an electron detector to sense secondary electron emissions caused by the electron stream's impact on the substrate. In an alternative embodiment, multiple CRT guns can be used in conjunction with a common vacuum chamber, either sharing a common electron detector or having individual electrostatically isolated detectors. This system is particularly useful for detecting flat panel displays (FPDs) during their manufacturing process.

Another significant patent involves a system for testing field emission flat panel displays (FEFPDs). This system places the FEFPD in a vacuum and measures electron stream emissions from selectively activated pixels. Selective activation is achieved through a linear stage mechanism associated with each contact pad of the FEFPD. Each mechanism consists of an electrically conducting ball bearing that rolls over the contact pad, completing an electrical circuit between an activation signal source and the electrodes of the pixel under test.
