Title: Innovations of Lap Man Yam
Introduction
Lap Man Yam is a notable inventor based in Saratoga, CA (US). He holds 2 patents that showcase his contributions to display technology. His work focuses on improving the efficiency and functionality of flat screen displays.
Latest Patents
One of his latest patents is for a cold cathode field emitter flat screen display. This invention features strips of field emitters arranged in rows that overlap grid electrodes, defining pixel dots when viewed. Scanning electrical voltages are applied to the rows of field emitters to perform scanning, while data potentials control the brightness of the display. Additionally, potentials applied to the grid electrodes focus the electrons from the field emitters. The design incorporates a metal mesh with grid electrodes, simplifying the manufacturing process of the display.
Another significant patent is for a display device with an improved grid structure. In this invention, a rim made of glass or ceramic material is attached to an alloy sheet with through holes at elevated temperatures. Voltages applied to the sheet focus electrons onto a phosphor layer for image display. An optional insulating layer and grid electrodes can be formed on the sheet for addressing and focusing. The rim maintains the alloy sheet in tension, ensuring proper alignment of holes and electrodes despite temperature variations. This innovative design allows for a combined electrode structure as thin as 3 millimeters, making it suitable for ultrathin large screen displays.
