En cần nhờ dịch giúp 1 đoạn văn tiếng Anh này, cần gấp lắm mong mọi người giúp đỡ

Cái khó là đoạn văn này rất dài và có rất nhiều từ tiếng anh chuyên ngành điện tử rất khó mà em đã dùng các phần mềm từ điển chuyên ngành như prodict, evatran... tra cứu nhưng không được, dùng google dịch thì lại không thể sát nghĩa được. Bạn nào giỏi về tiếng anh chuyên ngành kỹ thuật điện tử thì giúp đỡ em nhé. Thanks.
A field emission display (FED) is a low power, flat cathode ray tube type display that uses a matrix-addressed cold cathode to produce light from a screen coated with phosphor materials. The principle of the field emission display is similar to that of the tra***ional cathode ray tube display. Field emission displays, like cathode ray tubes, display a color image by emitting light of a predetermined color through the bombardment of electrons onto a field emitter array (FEA) coated with phosphor. They both emit electrons to hit the fluorescent medium on a substrate in vacuum. Electron emission includes field electron emission, secondary electron emission, and photoelectric emission, as well as thermionic emission. A cold cathode is the cathode that performs electron emission by field electron emission, which occurs due to a tunnel effect when a strong electric field is applied to the vicinity of the surface of a substance to lower the potential barrier on the surface. The cathode ray tube display emits electron beams by a single electron gun and controls the direction of the electron beams by using a polarization plate. Instead, the field emission display is composed of hundreds of thousands of active cold emitters, each of which corresponds to a pixel independently, so no polarization plate is needed. Field emission displays (FEDs) apply a strong electric field from a gate to a field emitter disposed on a cathode layer at regular intervals, thereby emitting electrons from the field emitter, colliding the electrons with a phosphor material of an anode layer, and emitting light. The cold cathode electron source is broadly divided into a field emission electron source and a hot electron type electron source. The former includes a spindt type electron source, a surface conduction type electron source and a carbon nanotube type electron source. The latter includes an MIM (metal-insulator-metal) type electron source stacked with metal-insulator-metal and an MIS (metal-insulator-semiconductor) type electron source stacked with metal-insulator-semiconductor. When displaying an image in the field emission display, a driving method called a line sequential scanning scheme is used standardly. Display in each of the frames is performed for each scan line (horizontally). All the cold cathode electron sources corresponding to the number of data lines on the same scan line are operated at the same time.
A field emission display typically includes an electron emission tip configured for emitting a flux of electrons upon application of an electric field to the field emission device. An array of miniaturized field emission devices can be arranged on a plate and used for forming a visual display on a display panel. The emission tip is specifically shaped to facilitate effective emission of electrons, and may for example be conical, pyramidal, or ridge-shaped in surface profile, or alternatively the tip may comprise a flat emitter surface of low work function material. In the initial FEDs, the emitters were formed of what are referred to as Spindt-type metal tips (or microtips). A main material of the metal tips is molybdenum. In a field emission display, several hundreds to thousands of micro tips or carbon nanotubes (CNTs) per pixel are provided as an electron emission source on a back plate of FED, and a phosphor layer emitting a light by an electron from the electron emission source is formed on a front plate of FED. To generate the field needed for release of electrons, a matrix of switchable row and column electrodes is typically provided, in ad***ion to the anode, and in this way pixels can be individually addressed. In order for the electron to travel in a FED, most FEDs are evacuated to a low pressure in order to provide a log mean free path for the emitted electrons and to prevent contamination and deterioration of the microtips. The resolution of the display can be improved by using a focus grid to collimate electrons drawn from the microtips. Field emission displays include an array of pixels, each of which includes one or more substantially emitter tips. The array of pixels of a field emission display is typically referred to as a field emission array. Each of the emitter tips is electrically connected to a negative voltage source by means of a cathode conductor line, which is also typically referred to as a column line. Another set of electrically conductive lines, which are typically referred to as row lines or as gate lines, extends over the pixels of the field emission array. Row lines typically extend across a field emission display substantially perpendicularly to the direction in which the column lines extend. As electrons are emitted by emitter tips and accelerate past the row line that extends over the pixel, the electrons are directed toward a corresponding pixel of a positively charged electro-luminescent panel of the field emission display. As electrons impact a pixel of the electro-luminescent panel, the pixel is illuminated
