    • An improved FED driving method, which uses a voltage control different from the prior FED, to turn an electron beam on/off and increase the resolution. The improved FED driving method is characterized in increasing a positive voltage applied to the FED's anode, grounding the FED's emitter and applying a negative voltage to the FED's gate. When driving the FED, the anode can pull electron beam out of the cathode with high accelerate voltage and the applied negative voltage on the gate can turn the electron beam on/off. As such, this allows a higher resolution because the electron beam is not influenced by the gate's lateral attraction and high lighting efficiency with high anode accelerate voltage.
    • 使用与先前的FED不同的电压控制的改进的FED驱动方法来打开/关闭电子束并提高分辨率。 改进的FED驱动方法的特征在于增加施加到FED阳极的正电压,将FED的发射极接地并向FED的门施加负电压。 当驱动FED时,阳极可以以高加速电压将电子束拉出阴极,并且栅极上施加的负电压可以打开/关闭电子束。 因此,这允许更高的分辨率,因为电子束不受栅极的横向吸引和高阳极加速电压的高照明效率的影响。

    • A method of CNT field emission current density improvement performed by a taping process is disclosed. The method comprises following steps. First of all, a conductive pattern coated on a substrate by screen-printing a conductive slurry containing silver through a patterned screen is carried out. Thereafter, a CNT layer is attached thereon by screen-printing a CNT paste through a mesh pattern screen to form CNT image pixel array layer. The CNT paste consists of organic bonding agent, resin, silver powder, and carbon nano-tubes. After that the substrate is soft baked by an oven using a temperature of about 50-200° C. to remove volatile organic solvent. A higher temperature sintering process, for example 350-550° C. is then carried out to solidify the CNT on and electric coupled with the conductive pattern. Finally, an adhesive film is closely attached on the cathode substrate and then remove the adhesive film away so as to remove those badly bonding CNT portions and to vertically pull up a portion of CNT which originally laid down on the surface of CNT layer after sintering. Consequently, the current density, brightness, and uniformity of the emitter sources are significantly improved.
    • 公开了一种通过胶带加工进行CNT场发射电流密度改进的方法。 该方法包括以下步骤。 首先,通过丝网印刷通过图案化屏幕的含银的导电浆料,涂覆在基材上的导电图案。 此后,通过网状图案丝网印刷CNT浆料将CNT层附着在其上,形成CNT图像像素阵列层。 CNT浆料由有机粘合剂,树脂,银粉和碳纳米管组成。 之后,使用约50-200℃的温度通过烘箱软化基底。 去除挥发性有机溶剂。 较高温度的烧结工艺,例如350-550℃。 然后进行CNT的固化并与导电图形电耦合。 最后,将粘合膜紧贴在阴极基板上,然后将粘合膜去除,以便去除这些不良接合的CNT部分,并且在烧结之后垂直拉起原来放置在CNT层表面上的一部分CNT。 因此,发射源的电流密度,亮度和均匀性显着提高。
