Description of the Invention: [Technical Field] The present invention relates to a drive module for a field emission display having a current detection.曰— 【Prior Art】 In recent years, with the advancement of display technology, various new exhibitions and popularizations, such as LCD monitors, qled, and field emission display (FED). The display of some new generations, due to the advantages of flat surface, thin volume, and other advantages, compared with the traditional cathode ray tube, the display benefits of these new generations have gradually replaced Conventional old cathode ray tube display (CRT): Among these new generation displays, the field emission display has a display principle similar to that of the lang, and all of them use the emission electrons to hit the screen to produce red (four) two primary colors to achieve display. The purpose of this is because of "ThinCRT,,. The difference is that the cathode ray tube _!,:=:= 2 light material of the high-speed electron beam makes it illuminate, and by adjusting it, it will be dark on the screen. _総轴# 宰宰文:单The field emission display uses the principle of tens of thousands of tips to generate a large-end discharge to emit an electron beam, through the ink to each:: Xin's electron beam directly forwards to the corresponding pixel to make the hormone The phosphor is illuminated by the fork. 201104654 In terms of construction, cathode ray tube displays require sufficient temperature-shifted electron beams for deflection. The field emission display does not need to be controlled by the magnetic field to control the deflection of the electron beam. The electron beam directly illuminates the electrons of the electrons to cause the phosphors of the respective elements to be excited to emit light, so that the distance from the anode to the anode can be A large inspection to K2 mm (_). (4) The interference of the electron beam emitted by the field in the field, the electric field of the pole and the anode plus the electric field, so that it does not need to be preheated as the hot cathode electron source needs to be preheated, 9 is broken because the electron beam directly excites the fluorescent light to emit light, so Also, the characteristics of rate consumption, high brightness and wide viewing angle. , 育低功 The first picture shows a single picture of the field material. The surface field emission display unit 1 has an upper substrate n and a lower substrate 12, a plurality of cathode electrodes 13 are disposed on the earth plate 12, an anode electrode 14 is disposed under the upper bell, and the cathode electrode 13 and the anode are electrically connected. A plurality of electron beam pairs are formed on the cathode electrode 13, and a plurality of cathodes 13 and a plurality of 徊@^ 兀8 are formed between the cathode electrodes 13 and the plurality of anodes θβ~ have a number of edges I 17 to isolate the dangerous electrode 13 'On the anode electrode 14 two negative 16 and a plurality of fluorescent layers 15 are placed; f black matrix placed on the upper substrate „ spot=2 plural spacers 19 her, ab & To the struts, the gap between the upper substrate and the lower substrate is maintained, and the gap between the two gates must be kept under the condition of high true working degree. Among them, the anode electrode u is composed of a plurality of non-connections (10). And n, layer or 疋 increase the transmittance; the phosphor layer 15 is produced by:: guiding two powder or self-lighting #光粉赖成; electronic a two-color fluorescent first-tip metal conductor or a plurality of m "== 201104654 For example: I mesh (Mo), carbonizer under different time of use, the conductors have low-tech materials, (TiC), tungsten (w), stone Xi (&) and the like. The second figure shows a schematic diagram of the relationship between current and voltage for a conventional field emission display. The electricity: when the display unit 10 is used at the initial time τι, there will be a better voltage characteristic: Ϊ之., the relationship 'such as the current corresponding to the initial time T1 - such as: to the Japanese p / το. After the field emission display unit 10 is used for a period of time, the material is combined, and the element of the electron beam emitting unit 18 on the cathode electrode 13 is used for the deterioration of the fading. Therefore, the field emission display shows that the voltage characteristic curve of the single 旌 即 will be The beginning of the recession is as determined by time T2: the characteristic curve of the ancient sore voltage, that is, the condition of the field emission display unit 10: =1. If it is continued for a period of time, it will eventually lead to the end of the field emission command unit 1G. The right 疋 is applied between the first electrode 13 and the anode electrode 14 at the initial time T1, and the electron beam emitting unit generates an electron beam toward the anode electrode 14, and the anode electrode 14 receives the sub-electrode. The beam intensity is the driving current of the current_voltage characteristic curve represented by the initial _T1 of the second w! Hey. #Series Using a period _ to time Η, the display quality of the field emission display unit 1G starts to deteriorate. For example, the current driving voltage representative curve of the time Τ2 provides only the lower driving current 12 by providing the same driving voltage %. This means that the same driving voltage V1 is applied to the initial time T1 and the time T2, and the cathode electrode 13 and the anode electrode η generate electrons, and the intensity is reduced from the driving current η to the driving current 12, and the field is emitted. . The brightness of the light will decrease. Therefore, the rate at which the material of the cathode electrode 13 of the field emission display unit 10 deteriorates is a major factor affecting the life of the field emission display. 201104654 SUMMARY OF THE INVENTION Embodiments of the present invention provide: a power supply that generates a power supply 显示器 display driver module, a source electrical connection, receives the power supply sharp and ^: a drive circuit, and the a transmitting display unit, which generates a driving signal supply path, electrically connected to the driving circuit, a sentence current; a current detecting electric-detecting signal; and - controlling electricity:,:: driving current, and According to the production number.
