Provided is a liquid cell for an electron microscope according to an embodiment of the inventive concept, including a lower window layer, an upper window layer above the lower window layer, and a separation film disposed between the upper window layer and the lower window layer so as to separate the upper window layer and the lower window layer from each other. An upper space may be defined by the upper window layer and the separation film, and a lower space may be defined by the lower window layer and the separation film. The upper window layer, the lower window layer, and the separation film may include the same material.

Liquid cell for electron microscope and manufacturing method thereof

Disclosed in the present application is a mobile terminal having a flexible display. The present application may provide the mobile terminal comprising: a first frame; a second frame movably attached to the first frame and configured to move in a first direction or a second direction opposite to the first direction with respect to the first frame to form a predetermined stroke; a third frame movably combined with the second frame and configured to move in the first direction or the second direction with respect to the second frame; a flexible display arranged on the front surface of the mobile terminal; a driving unit configured to move the second frame in the first or second direction with respect to the first frame and move the third frame in the first or second direction with respect to the second frame; a detecting apparatus configured to detect the extent of movement of the second frame in the first direction or the second direction; and a control apparatus configured to control the operation of the mobile terminal on the basis of the extent of movement of the second frame measured by the detecting apparatus.

Mobile terminal

A mobile terminal comprises a first frame, a second frame capable of slidably moving from the first frame in a first direction or a second direction which is an opposite direction of the first direction, and a driving unit slidably moving the second frame, wherein the driving unit includes a motor coupled to the first frame, a pinion gear rotated by a rotational force transferred from the motor, a gear rack extended in the first direction and coupled to the second frame, moving in the first direction or the second direction when the pinion gear is rotated, a guide rail coupled with the gear rack, and a guide block coupled to the first frame, moving along the guide rail.

A quantum dot electronic device comprises a first encapsulation layer, a first electrode disposed on the first encapsulation layer, a quantum dot pattern disposed on the first electrode, a second electrode disposed on the quantum dot pattern and a second encapsulation layer disposed on the second electrode. The quantum dot pattern may be formed by an intaglio transfer printing method, where the method comprises forming a quantum dot layer on a donor substrate, picking up the quantum dot layer using a stamp, putting the quantum dot layer into contact with an intaglio substrate using the stamp and separating the stamp from the intaglio substrate. Using the quantum dot transfer printing method, a subminiature quantum dot pattern can be transferred at a high transfer rate. Accordingly, a highly integrated quantum dot electronic device exhibiting excellent performance and a high integrated quantum dot light emitting device with an ultrathin film can be realized.
