Embodiment Construction

[0052] Hereinafter, some embodiments of the present invention will be described in detail with reference to schematic drawings. Where reference numerals are used to designate elements of the drawings, the same reference numerals will be used to designate the same elements even though the elements are shown in different drawings. Also, in the following description of the present invention, detailed descriptions of known functions and configurations incorporated herein will be omitted when they may make the subject matter of the present invention actually unclear.

[0053] In addition, terms such as first, second, A, B, (a), (b), etc. may be used herein in describing components of the present invention. Each of these terms is not used to define the nature, sequence or order of the corresponding component, but is only used to distinguish the corresponding component from other components. When it is described that a certain structural element is "connected to", "coupled to" or "c...

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2015-0083137 filed on Jun. 12, 2015, which is hereby incorporated by reference as if fully set forth herein for all purposes. technical field [0003] Embodiments of the present invention relate to a level shifter, a source driver integrated circuit and a gate driver integrated circuit. Background technique [0004] Electrical devices, such as display devices, may contain level shifters for changing the voltage levels of various voltage signals to desired voltage levels. [0005] The level shifter is configured as a circuit including a plurality of transistors to output a high voltage level output signal shifted by receiving a low voltage level input signal. Additionally, when a conventional level shifter intends to change the voltage level of an input signal to a voltage level of a desired level, the conventional level shifter does not quickly cha...
