Description

technical field [0001] The invention belongs to the field of flat panel display technology, the field of vacuum science and technology, and the field of nano science and technology. Production, in particular to a flat panel display with a right-angle three-dimensional double-straight gate-controlled oblique arc cathode structure and a production process thereof. Background technique [0002] Flat-panel displays generally refer specifically to devices whose display screens are completely flat. But so far I can't give you a strict definition. The field emission display is a new type of flat panel display device, which is named after its cathode material emits a large number of electrons in the form of "field emission". After the electrons emitted from the cathode are accelerated, they bombard the phosphor layer of the anode. It emits visible light to generate images, and its working principle is basically the same as that of a CRT display. The emergence of carbon nanotube m...

Problems solved by technology

For the field emission flat panel display with a three-pole structure, its advantages and disadvantages coexist. The advantage is that the addition of the grid structure can further reduce the operating voltage of the device; the disadvantage is that due to the grid structure Addition, resulting in non-simplified device manufacturing structure, complicated manufacturing process, and put forward higher requirements for the manufacturing materials of the gate structure.

The three-electrode structure field emission display currently developed generally has defects such as too high gate operating voltage and too large gate operating current, and it still needs to invest a lot of time and materials for research and development.
