Abstract: A battery cell extraction device includes an adsorption part provided to be movable toward a battery cell stored in a tray, and provided to adsorb a first surface of the battery cell, and a guide part provided to be movable so that in a state where the first surface of the battery cell is adsorbed by the adsorption part, a second surface in a direction opposite to the first surface of the battery cell is supported, and including a plurality of elastic members disposed to contact the second surface of the battery cell.

Abstract: The present invention has been made in an effort to provide a circuit for generating driving voltages, a liquid crystal display, and a method of generating driving voltages having advantages that a plurality of driving voltages are not reduced so that desired grays are displayed and the contrast ratio is not deteriorated. For this purpose, driving voltages are generated using a battery voltage outputted from a battery of a mobile device according to an embodiment of the present invention. In this manner, by generating a source voltage VS and a common voltage Vcom using a battery voltage V_BAT, the reduced amounts of the source voltage VS and the common voltage Vcom are lessened, and therefore, voltages required by the specifications can be maintained. As a result, black is displayed more darkly or white is displayed more brightly, so that the contrast ratio C/R of a display device can be increased.
