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.

The present disclosure relates to a flexible substrate for a display device including a plastic layer containing a woven glass fiber, a metal film coated on either both side surfaces or one surface of the plastic layer, and an overcoating layer formed on one surface of the metal film wherein the overcoating layer is on the side of the metal film opposite from the plastic layer, and to a display device using the flexible substrate. The flexible substrate is thin, and has small thermal expansion coefficient, excellent flexibility, heat resistance, gas permeability resistance and moisture blocking property. The flexible substrate can be used in various display devices such as a TV, a notebook computer, a cellular phone, or an electronic paper.

An organic light emitting display and a manufacturing method thereof include an improved encapsulation layer. The encapsulation layer of the organic light emitting display includes an organic layer uniformly covering bank portions and light emitting areas on a substrate; and an inorganic layer formed thicker on the light emitting areas than on the bank portions. In the organic light emitting display, the inorganic layer is thick on the light emitting area in which a sealing ability is required and the bank portion is thin in order to provide flexibility. Therefore, the encapsulation layer can be formed more easily compared to an encapsulation layer on a device in which the organic layer and inorganic layer are alternately formed at least 10 times.
