    • An inkjet printhead having a cantilever actuator, the inkjet printhead including a plurality of ink chambers containing ink to be ejected; a manifold containing ink to be supplied to the plurality of ink chambers; a plurality of restrictors supplying ink to the plurality of ink chambers from the manifold; a plurality of nozzles ejecting ink from the plurality of ink chambers; and a plurality of cantilever actuators each installed in each of the plurality of ink chambers and having one fixed end and the other deflectable end, such that pressure for ejection of ink is applied due to the deflection of the other end of the cantilever actuator to the ink inside the ink chamber. The cantilever actuator may be made of a bimorph element, eject ink through the nozzle from the ink chamber, and also prevent backflow of ink from the ink chamber to the restrictor by virtue of the deflection of the other end thereof. Since the cantilever actuator can have a greater displacement and can prevent backflow of ink, the size of the ink chamber needed to eject ink droplets of uniform volume can be reduced, and thus the number of channels per inch (CPI) of the inkjet printhead can be increased.
    • 一种具有悬臂致动器的喷墨打印头,所述喷墨打印头包括多个墨室,所述多个墨室容纳要喷射的墨; 含有供给多个墨水室的墨水的歧管; 多个限制器,从多个歧管向多个墨水室供墨; 多个喷嘴从所述多个墨室喷射墨; 以及多个悬臂致动器,每个安装在所述多个墨室中的每一个中并且具有一个固定端和另一个可偏转端,使得由于所述悬臂致动器的另一端的偏转而施加用于喷射墨的压力 油墨室内的墨水。 悬臂致动器可以由双压电晶片元件制成,通过喷嘴从墨室喷射墨水,并且还防止墨水由于其另一端的偏转而从墨水室回流到限制器。 由于悬臂致动器可以具有更大的位移并且可以防止墨的回流,所以可以减少喷射具有均匀体积的墨滴所需的墨室的尺寸,因此喷墨打印头的每英寸通道数(CPI)可以 增加。

    • An inspection apparatus for a TFT substrate formed with a plurality of pixels, includes a reference substrate being opposite to and spaced from the TFT substrate and formed with a plurality of reference patterns corresponding to the pixels, a power supply to supply power to both a predetermined number of the pixels and the corresponding reference pattern to form an electric field in a space between the TFT substrate and the reference substrate, an electron beam emitter to emit an electron beam to travel from a first side to a second side of the space, an electron beam detector to detect the electron beam emitted from the electron beam emitter and passed through the space, and a controller to determine whether the TFT substrate includes a defective pixel based on a location of the electron beam detected by the electron beam detector. Thus, the inspection apparatus can correctly and quickly inspect the TFT substrate for defects in a low vacuum state regardless a size of the TFT substrate.
    • 一种用于形成有多个像素的TFT基板的检查装置,包括与TFT基板相对并且与TFT基板隔开的基准基板,并且形成有与像素对应的多个基准图案,供给两个预定的 像素数和相应的参考图案,以在TFT基板和参考基板之间的空间中形成电场,发射电子束从空间的第一侧移动到第二侧的电子束发射器, 电子束检测器,用于检测从电子束发射器发射并通过空间的电子束,以及控制器,用于基于由电子束检测器检测到的电子束的位置来确定TFT基板是否包括缺陷像素。 因此,与TFT基板的尺寸无关地,检查装置可以正确且快速地检查TFT基板中的低真空状态的缺陷。
