The invention relates to a
flat panel display with hat-shaped bottom grid-controlled
cathode structure and its manufacturing process, which includes a sealed
vacuum chamber composed of an
anode glass panel, a
cathode glass panel and surrounding glass frames; layer and the
phosphor layer prepared on top of the
anode conductive layer; the
supporting wall structure and
getter accessory components between the
anode glass panel and the
cathode glass panel, and the grid lead layer, carbon nanotubes and cap type on the cathode glass panel Bottom-gate-controlled cathode structure; it can reduce the working
voltage of the grid, improve the display brightness of the overall device, and reduce the working current of the grid. It has the advantages of stable and reliable manufacturing process, simple manufacturing process, low manufacturing cost and simple structure.
